GENERAL DESCRIPTION
The BOBCAT cameras are advanced, intelligent, high-resolution, progressive scan, fully
programmable and field upgradeable CCD cameras. They are built around SONY’s and
KODAK’s line of interline transfer CCD imagers. BOBCAT cameras are feature rich with
built in image processing engine (based on a 2 million gates FPGA), have small size, very
low power consumption, low noise, and efficient and optimized internal thermal
distribution. The BOBCAT cameras feature programmable image resolution, frame rates,
gain, offset, asynchronous external triggering with programmable exposure, fast triggering,
double exposure and capture duration, electronic shutter, long time integration, strobe
output, transfer function correction, temperature monitoring and user programmable and
up-loadable LUT. A square pixel provides for a superior image in any orientation. The
interline transfer CCD permits full vertical and horizontal resolution of high-speed shutter
images. The combination of electronic shutter and long time integration enables the
cameras capturing speed to be from 1/500,000 second to more than 16 seconds. A built-in
Gamma correction and user LUT optimizes the CCD‘s dynamic range. The cameras have a
standard GEV or Camera Link™ interface that includes 8/10/12/14 bits data transmission
with one or two output taps as well as camera control and asynchronous RS232 serial
communication interface, all on a single cable. The cameras are fully programmable via the
serial interface using a GUI based configuration utility. The adaptability and flexibility of
the camera allows it to be used in a wide and diverse range of applications including
machine vision, metrology high-definition imaging and surveillance, medical and scientific
imaging, intelligent transportation systems, character recognition, document processing and
many more.

1.3.1 General Information
A CCD camera is an electronic device for converting light into an electrical signal.
The camera contains a light sensitive element CCD (Charge Coupled Device) where
an electronic representation of the image is formed. The CCD consists of a two
dimensional array of sensitive elements – silicon photodiodes, also known as pixels.
The photons falling on the CCD surface create photoelectrons within the pixels,
where the number of photoelectrons is linearly proportional to the light level.
Although the number of electrons collected in each pixel is linearly proportional to
the light level and exposure time, the amount of electrons varies with the
wavelength of the incident light. When the desired exposure is reached, the charges
from each pixel are shifted onto a vertical register, VCCD, and then one row
downwards in a vertical direction towards a horizontal register, HCCD. After that
the electrons contained in the HCCD are shifted in a horizontal direction, one pixel
at a time, onto a floating diffusion output node where the transformation from
charge to voltage takes place. The resultant voltage signal is buffered by a video
amplifier and sent to the corresponding video output. There are two floating
diffusions and two video amplifiers at each end of the HCCD, and the charges can
be transferred towards any of the outputs (depending on the mode of operation).
The time interval required for all the pixels, from the entire imager, to be clocked
out of the HCCD is called a frame. To generate a color image a set of color filters
(Red, Green, and Blue) arranged in a “Bayer” pattern, are placed over the pixels.
The starting color is typically Green for Kodak CCDs and Red for SONY CCDs,
but it varies from CCD to CCD. Figure 1.0 shows the CCD pixel structure. Table
1.1 shows the individual pixel structure for different BOBCAT cameras. Effective
pixels image consists of Active and Buffer pixels. Figures 1.1a, b, c and 1.2a,b
show the camera’s spectral response. Figure 1.3 shows the Bayer patter
arrangement.

Power Supply
The camera Link version of the camera is compatible with power over camera Link
– PoCL, with a maximum power of 4 W.
If PoCL is not available, a universal desktop power supply adapter, providing +12
VDC, +/- 10%, and up to 2.5A constant DC current, is available (for additional
price) from Imperx for the BOBCAT cameras. The operating input voltage ranges
from 90 to 240 VAC.
CAUTION NOTE
1. It is strongly recommended that you do not use an adapter other than the one
that is available from Imperx for the camera!
2. The PoCL current is limited to 333 mA. The cameras are PoCL compatible in
normal camera operation – free running with full image. In some modes such as
vertical binning x4 and x8 and in AOI (with keep frame rate disabled), when the
vertical height is less than 100 lines, the camera current can exceed 333 mA.

1.5.2 Optical
The smaller body BOBCAT cameras (45 x 45) mm cross-section come with an
adapter for C-mount lenses, which have a 17.52 mm back focal distance – Figure
1.9a and Figure 1.9b. An F-mount lens can be used with a C-mount camera via an
F-mount to C-mount adapter, which can be purchased separately – refer to the
Imperx web site for more information. The bigger body BOBCAT cameras (60 x
60) mm cross-section come with an adapter for F-mount lenses, which have a 46.50
mm back focal distance – Figure 1.9c. The camera performance and signal to noise
ratio depends on the illumination (amount of light) reaching the sensor and the
exposure time. Always try to balance these two factors. Unnecessarily long
exposure will increase the amount of noise and thus decrease the signal to noise
ratio.
The cameras are very sensitive in the IR spectral region. All color cameras have and
IR cut-off filter installed. The monochrome cameras are without IR filter. If
necessary, an IR filter (1 mm thickness or less) can be inserted under the front lens
bezel.
CAUTION NOTE
1. Avoid direct exposure to a high intensity light source (such as a laser beam).
This may damage the camera optical sensor!
2. Avoid foreign particles on the surface of the imager.
1.5.3 Environmental
The camera is designed to operate from -300 to 600 C in a dry environment. The
relative humidity should not exceed 80% non-condensing. Always keep the camera
as cool as possible. Always allow sufficient time for temperature equalization, if the
camera was kept below 00 C!
The camera should be stored in a dry environment with the temperature ranging
from -500 to + 700 C.
CAUTION NOTE
1. Avoid direct exposure to moisture and liquids. The camera housing is not
hermetically sealed and any exposure to liquids may damage the camera
electronics!
2. Avoid operating in an environment without any air circulation, in close
proximity to an intensive heat source, strong magnetic or electric fields.

2.1
IMAGE RESOLUTION
The image resolution is determined by the number of pixels per line and number of lines
per frame. The image is framed by two signals LVAL, enveloping the valid pixels in a line,
and FVAL – enveloping the valid lines in a frame. The camera offers two independently
selectable LVAL and FVAL sizes. The first LVAL value envelops all visible pixels in a
line (active pixels plus buffer pixels) and the second – only the active pixels. Respectively,
the first FVAL envelops all visible lines in a frame (active lines and buffer lines), and the
second – only the active lines. The camera speed (Frames per Second) is the same for both
image size selections. Typically, the pixels outside of LVAL and FVAL (primarily dark
pixels and lines) are masked with zeros, but in BOBCAT, the user has an option to mask or
not to mask these pixels or lines. Refer to section “BOBCAT Configuration” for more
information.
Camera models B0610, B1410and B1610 are available only with a single output. Models
B0620, B1620 and B1920 are available in single or dual, and B2520 is available only with
dual output. In some camera models a high readout mode is available as described below.
2.1.1
Normal Mode – Single Output
When operating in the single output mode, all pixels are shifted out of the HCCD
register towards the left video amplifier – Video L (Figure 2.1). The resulting image
has a normal orientation.

2.1.2
Normal Mode – Dual Output
When operating in a dual output mode, the image is split in two equal parts, each
side consisting of half of the horizontal pixels and the full vertical lines. The first
(left) half of the pixels are shifted out of the HCCD register towards the left video
amplifier – Video L, while the second (right) half of the pixels are shifted towards
the right video amplifier – Video R (Figure 2.2). In the horizontal direction the first
half of the image appears normal and the second half is left/right mirrored. The
camera reconstructs the image by flipping the mirrored portion and rearranging the
pixels. Dual output is the default factory mode of operation – refer to the
Configuration Memory section. The image resolutions for different cameras are
shown in Table 2.1, and a frame rates – in Table 2.2.

Center Mode
A.
B0610 and B0620 Models
The ‘center columns’ output mode is available in the B0610 and B0620 camera
models. In this mode the image field has only 228 horizontal pixels located in the
center of the imager – Figure 2.3. When operating in a single output mode, all 228
pixels are shifted out of the HCCD register towards the left video amplifier – Video
L (Figure 2.4). The resulting image has a normal orientation. When operating in a
dual output mode, the image is split in two equal parts, each having 114 pixels and

B1410, B1610 and B2520 Models
To achieve a higher frame rate B1410, B1610 and B2520 camera models can
provide a fast readout, where every the image is sub-sampled – 2 out of 8
lines/pixels are read out of the CCD – Figure 2.6. The image resolutions for
different cameras are shown in table 2.1a, and a frame rates – in Table 2.2.

FRAME TIME CONTROL
2.2.1 Internal Line and Frame Time Control
The camera speed (frame rate) depends on the CCD “read-out” time – the time
necessary to read all the pixels out of the CCD imager. The frame rate can be
calculated using the following Formula 1.1:
Frame rate [fps] = 1 / read-out time [sec]
(1.1)
The user can program the camera to run slower than the nominal speed preserving
the camera full resolution. The user can independently extend the camera line time
(the time required to read one line out of the CCD imager) and camera frame time
(the time required to read the entire frame out of the CCD imager). The camera line
time can be extended to ~ 200 us, with a precision ~ 25 ns. The camera frame time
can be extended to ~ 16 sec, with a precision of ~ 1.0us. Please refer to
“EXPOSURE CONTROL” section for more information.
CAUTION NOTE
It is not recommended to use the Programmable Line Time feature when Vertical
Binning higher than 2x is used!
2.2.2 Camera Speed Control
BOBCAT camera series provides a unique way to control and increase the camera
nominal (free-running) speed. The user can select (Slow) or (Fast) camera speed.
The “Slow” speed is the camera nominal frame rate as determined by the CCD
manufacturer. Since BOBCAT internal design is optimized for higher clock rates, it
is possible to over-clock the camera (use an internal clock higher than the
recommended one), which will result in higher (~ 20%) frame rate. Special
measures have been taken in order to preserve the camera performance when overclock mode is used. The possible frame rates are shown in Table 2.2, where the
camera speed is the shown in [FPS)]. The first number represents the “Slow” speed,
and the second – “Fast” speed.

CAUTION NOTE
1. Changing the camera speed involves changing the output data clock frequency. Not all
frame-grabbers can automatically adapt to the new data clock. To prevent any loss of
data or synchronization, it is recommended to stop or pause the data acquisition prior to
changing the camera speed.
2.2.3 External Line and Frame Time Control
The camera speed (frame rate) can be controlled using external sync pulses. The
camera line time can be slaved to an external H-Sync pulse, and the camera frame
time can be slaved to an external V-Sync pulse. The camera can be slaved to one or
both pulses. The H-Sync and V-Sync has to be mapped to corresponding camera
input. For more information, please refer to the I/O Control section.

AREA OF INTEREST
2.3.1 Horizontal and Vertical Window
For some applications the user may not need the entire image, but only a portion of
it. To accommodate this requirement BOBCAT provides total of 8 (eight)
Horizontal and Vertical Areas of Interest (AOI) – one Master, 6 Slave and one
Processing. The starting and ending point for each AOI can be set independently in
horizontal direction (Horizontal Window) and vertical direction (Vertical Window),
by setting the window (H & V) offset and (H & V) size – Figure 2.7. The minimum
window size is one pixel/line for single mode and two pixels/lines for dual mode.
The maximum horizontal window size (H) and the vertical window size (V) are
determined by image full resolution as shown in Table 2.1, and the selected size of
LVAL and FVAL.
Figure 2.7 – Horizontal and vertical window positioning.
A.
Master AOI (MAOI)
The MAOI can be set to preserve or to change the camera frame rate. When the user
wants to preserve the camera frame rate the MAOI settings will control only the
image H & V dimensions. When the user wants to take advantage of the reduced
vertical image size and increase the camera frame rate, the image maximum camera
speed will be determined by the V size of this MAOI. The image resolution will
reflect the MAOI H & V settings.

Slave AOIs
AOI1 to AOI6 are assigned as slave AOIs and they MUST be selected so they are
completely inside MAOI. All slave AOIs can be set independently with no
restrictions for overlapping and order – Figure 2.8. In addition, each AOI can be
included or excluded from the MAOI. In figure 2.8 AOI2 to AOI6 are included in
MAOI and AOI1 is excluded. The salve AOIs can be enabled in random order and
based on include/exclude selection can be inside each other.
Figure 2.8 – Slave AOIs.
C.
Processing AOI (PAOI)
All AOIs are functionally equal except PAOI. PAOI can be enabled as LUT or
image processing Region of Interest (ROI). When enabled as LUT ROI, the LUT
function will apply only to the selected ROI, all data outside of the region will not
be processed with the LUT function. When enabled as processing ROI, the selected
processing function will apply only to the selected ROI, all data outside of the
region will not be processed with the selected function – Figure 2.9.

(All data within the selected ROI are processed with “One Point
Correction”, all data outside of the ROI are not processed)
CAUTION NOTE
1. If the user needs to enable AOI1 to AOI6 MAOI MUST be enabled.
2. To qualify the selected pixels/lines MAOI uses DVAL, where DVAL is high
within the selected MAOI. The frame-grabber horizontal and vertical
resolutions must be adjusted for each window size
3. Horizontal and vertical windows can be enabled in all camera modes, including
H & V binning. Refer to binning section for more information.
4. The size of the horizontal window does not affect the camera frame rate, the
vertical window does, but only if “Keep Frame Rate” is not enabled.
5. For dual tap mode of operation the horizontal Offset and Width must be even
number.
6. For B1920 the minimum “Horizontal Offset” is 10 pixels when “Constant
Frame Rate” is disabled, and 0 pixels when “Constant Frame Rate” is enabled.
7. Positioning the horizontal and vertical window size outside the maximum image
window will result in an error.
8. Color version users – for proper color reconstruction ‘Offset X’ and ‘Offset Y’
must be an odd number.
2.3.2 Calculating the Frame Rate using Vertical Window
When camera frame rate changes with the size of the vertical window, the resulting
frame rate (FR) for each camera is shown on figure 2.10a – 2.10fg. The camera uses
an adaptive algorithm for the frame rate change, so it is difficult to put a simple

CAUTION NOTE
The CCD used in B1920 (KAI-2093) natively does not support increase frame rate with
reduced vertical frame size. Due to this, in some bright light scenes, blooming is possible.
If blooming occurs, please reduce the light by closing the lens or introduce an ND filter.

BINNING
Horizontal binning combines adjacent pixels in horizontal directions to effectively create
larger pixels and less resolution. BOBCAT supports 4 binning modes 2x, 3x, 4x and 8x. In
2:1 horizontal binning mode, two adjacent pixels in each line are summed together (in the
horizontal direction), for example, pixels 1+2, 3+4, 5+6, in each line are summed together.
Horizontal binning does not affect the frame rate. It does, however, reduce the horizontal
resolution by a factor of 2. This occurs because when binning two pixels together, only half
of the pixels per line remain. Horizontal binning 2:1 is equivalent to 2:1 sub-sampling in
the horizontal direction. The same rule applies for higher binning modes. In horizontal
binning mode, the entire image is captured and displayed, which is different than horizontal
windowing, where only a portion of the image is captured and displayed.
Vertical binning is a readout mode of progressive scan CCD image sensors where several
image lines are clocked simultaneously into the horizontal CCD register before being read
out. This results in summing the charges of adjacent pixels (in the vertical direction) from
two lines. BOBCAT supports 4 binning modes 2x, 3x, 4x, and 8x. In 2:1 binning for
example, the corresponding pixels in every two lines (1+2, 3+4, 5+6 …) are summed
together. Vertical binning reduces the vertical resolution by a factor of 2, and almost
doubles the frame rate. This occurs because when binning two lines together, only half of
the lines need to be read out. Vertical binning 2:1 is equivalent to 2:1 sub-sampling in the
vertical direction. The same rule applies for higher binning modes. In vertical binning the
entire image is captured and displayed, which is different than vertical windowing, where
only a portion of the image is captured and displayed.
Horizontal and Vertical binning can be used simultaneously – Figure 2.11. Horizontal and
vertical binning can work simultaneously with AOI. The corresponding image sizes and
frame rates for different binning modes are shown in Table 2.3a, Table 2.3b and Table
2.3c. “H size” shows the image size for different LVAL selections, “V size” shows the
image size for different FVAL selections, “Speed” shows the camera speed for slow and
fast speed modes. The speed difference is shown for the bigger LVAL/FVAL value.

Horizontal and vertical binning can work simultaneously with AOI. Although vertical and
horizontal binning are done in different domains, there are no differences in the way the
AOI with binning works.
Vertical Binning is done in the time domain, where the data from the binned lines is
added in the CCD. The vertical binning is performed first, and the vertical AOI is
second. The vertical AOI settings are referenced to the binned image. If the user wants to
set a vertical window of 200 lines, the user has to put 200 in the AOI height register
regardless off the selected vertical binning mode.
Horizontal Binning is done in the digital domain, where the data from the binned
pixels is added digitally. The horizontal binning is performed first, and the horizontal
AOI is second. The horizontal AOI settings are referenced to the binned image If the user
wants to set a horizontal window in the binned image with width 200 the user has to put
200 in the AOI width register regardless of off the selected horizontal binning mode.
Figure 2.11a illustrates the simultaneous usage of AOI and H & V binning. The original
image is 640 x 480. Then after 2 x 2 binning the resultant image is 320 x 240. Then a
master AOI is enabled with offset X = 80, offset Y = 120, width = 200 and height = 100.
Then a slave AOI is enabled with offset X = 50, offset Y = 30, width = 45 and height = 40.
In the left side the slave AOI is enabled in “Include” mode, and in the right side the same
AOI is enabled in “Exclude” mode. When enabled as “Include” only the selected slave AOI
region is displayed, the rest (of the master AOI) is black. When enabled as “Exclude” only
the selected slave AOI region is black, the rest is the selected master image
CAUTION NOTE
1. Vertical and horizontal binning cannot be performed when the Center mode is
used for B1410, B1610 and B1610.
2. Horizontal or vertical binning used alone changes the aspect ratio of the image
in the vertical or horizontal direction. To correct this, use identical horizontal
and vertical binning modes simultaneously.
3. The frame-grabber vertical and horizontal resolution should be changed to
reflect the actual number of active pixels and lines.
4. Vertical binning may cause blooming for saturated signal levels.
5. Color version users – horizontal or vertical binning used alone will create color
distortions. If used simultaneously, the resulting image will be monochrome.

EXPOSURE CONTROL
2.5.1 Internal Exposure Control - Electronic Shutter
During normal camera operation, the exposure time is fixed and determined by the
readout (frame) time. The electronic shutter can be used to precisely control the
image exposure time under bright light conditions. The electronic shutter does not
affect the frame rate; it only reduces the amount of electrons collected. Positioning
a short pulse “SHUTTER”, with respect to the vertical transfer pulse, VCCD –
Figure 2.12, sets the exposure time. The electronic shutter pulse can be positioned
within the entire frame period with a precision of 1.0us. The maximum exposure is
frame time dependent and the minimum exposure is ~ 2 microseconds (camera
dependent).
Frame Time
Exposure
VCCD
SHUTTER
Figure 2.12 – Electronic shutter position
2.5.2 External exposure control
The camera exposure can be controlled using an external pulse, supplied to the
camera. The pulse duration determines the exposure. For stable operation, this pulse
MUST be synchronized with the camera frame timing. Please refer to “I/O Control”
section for pulse mapping information.
2.5.3 Variable Frame Time – Programmable Line and Frame Time
Variable frame time mode provides the ability to run the camera in full resolution
and a frame rate slower than the nominal camera frame. This has two effects: 1) it
reduces the bandwidth requirements on the camera output and 2) it increases the
exposure time for the frame. During normal camera operation (no shutter), the
nominal frame rate determines the integration time. The desired frame rate, and thus
the new integration time, can be achieved by moving the vertical transfer pulse,

program the camera integration (frame time) from the nominal camera frame time

Frame rate [fps] = 1 / frame time [sec]

CAUTION NOTE
1. The maximum frame rate (and minimum frame time) is determined by the
camera mode of operation. If the user enters a higher frame rate than the
allowed one, the image will halt. Programmable Frame Time cannot be enabled
in Trigger mode.
2. When programmable line time and programmable frame time are to be enabled
simultaneously, enable line time first, set the appropriate line value, and then
enable the programmable frame time. If you change the line time value while
the frame time is enabled, please note that you might need to re-adjust the frame
time value.
3. If the frame time is greater than 500ms the camera has to be kept still otherwise
a motion smear will appear on the image.
2.5.4 Automatic Exposure Control (AEC)
The camera can be set to automatic exposure (and gain) control in order to keep the
same image brightness during changing light conditions. Both modes – automatic
exposure and automatic gain can be enabled simultaneously. In this mode the user
sets the image brightness (luminance) to be maintained, and the camera adjusts the
exposure accordingly. The user can select the average or peak brightness to be
maintained. The camera starts with changing the exposure within the preset by the
user min-max limits. If one of the exposure limits has been reached, the camera
indicates the limit has been reached and keeps the value until the light condition
change. The speed of convergence (how fast the camera stabilizes after change),
can be preset by the user (four possible options are available). The AEC algorithm

samples all pixels for the entire frame, but the user can select only a portion of the
image (AOI) to be used as a sample collecting region. The camera displays the
current luminance, current exposure and current gain. For auto gain control refer to
Automatic Gain Control (AGC) section.
CAUTION NOTE
1. In some bright light conditions a very small exposure values (~ microseconds)
must be used. In such cases the camera response is not linear, i.e. equal exposure
increments do not result in equal brightness increase. In some rare occasions during
such conditions, an image brightness oscillation (image flipping from bright to
dark) could occur. To prevent this, please change the AEC/AGC setting (exposure
speed, luminance level or AOI), or change the lens iris.
2.5.5 Automatic Iris Control (AIC)
The camera has a built in auto iris control feature, which is hardware compatible
with a "Video” auto iris lens. If enabled, the camera provides an analog video
signal (via 12 pin HIROSE connector), which is used by the lens to control the iris.

EXTERNAL TRIGGER
2.6.1
Triggering Inputs
In the normal mode of operation, the camera is free running. Using the trigger mode
allows the camera to be synchronized to an external timing pulse. There are three
input modes available for external triggering – software (CC), internal (pulse
generator), and external. Please note that the desired trigger input has to be mapped
to corresponding camera input. For more information, please refer to the I/O
Control section.
2.6.2
-
“External” – the camera receives the trigger signal coming from the connector
located on the back of the camera.
-
“Computer” – the camera receives the trigger signal command from the framegrabber.
-
“Internal” – the camera has a build in programmable pulse generator – refer to
“Pulse Generator” section. In Internal triggering mode the camera receives the
trigger signal from the internal pulse generator.
-
“Software” – the camera receives the trigger signal which is computer
generated. This input is available only for GigE Cameras. The camera expects a
one clock cycles pulse generated by the computer. The trigger exposure is
internal register controlled. Pulse duration exposure is not allowed.
Acquisition and Exposure Control
For each trigger input the user can set the trigger edge, the over-trigger conditions,
the de-bounce (de-glitch) time, the exposure time, the exposure delay, and the
number of frames captured.
1. “Triggering Edge” – the user can select the active triggering edge:
-
“Rising” – the rising edge will be used for triggering
-
“Falling” – the falling edge will be used for triggering
2. “De-bounce” – the trigger inputs are de-bounced to prevent multiple triggering
from ringing triggering pulses. The user has four choices of de-bounce interval:
-
“Off” – no de-bounce (default)
-
“0.1” ms de-bounce interval
-
“1.0” ms de-bounce interval
-
“10.0” ms de-bounce interval
3. “Trigger Overlap” – if the next trigger pulse arrives while the previous
triggering cycle is in process, the user has three options:

-
“Ignore” – the next rigger will be ignored, and the camera will continue its
present operation.
-
“Accept” – the next trigger will be used. The camera will stop the present
operation, will reset and the new trigger cycle will start.
-
“Accept after Exposure” – the next rigger will be ignored while the camera
is exposing the image. The next trigger will be used only after the image
exposure based on the previous trigger has been completed. The camera will
stop the present operation, will reset and the new trigger cycle will start.
4. “Exposure Time” – the exposure for all frames can be set in two ways:
-
“Pulse Width” – the trigger pulse width (duration) determines the exposure.
-
“Internal” – the camera internal exposure register determines the exposure.
A mid exposure pulse is generated in this mode.
5.
“Frames captured” – the number of frames captured after the trigger pulse
can be programmed from 1 to 65530 frames, or to be free-running.
CAUTION NOTE
1. The de-bounce interval MUST be bigger than the trigger pulse duration. Adjust
the interval accordingly.
2.6.3
Trigger Strobe Control
Along with the shutter pulse, the camera can send one strobe pulse for
synchronization with an external light source. The user can set the strobe pulse
duration and the delay with respect to the trigger pulse active edge. The maximum
pulse duration and the maximum delay can be set up to 16777215 us with 1.0us
precision. The strobe pulse can be assigned to “Strobe 1” or “Strobe 2. If the
number of frames captured is more than 1, and the user wants to enable the strobe
for the next frames, he/she has to using the camera strobe – please refer to “Strobe”
section for more information.
2.6.4
Triggering modes
A.
Standard Mode
When the standard triggering mode is enabled, the camera idles and waits for a
trigger signal. Upon receiving the external trigger signal, the camera clears the
horizontal and vertical registers, sends a shutter pulse to clear the pixels and starts
integration – Figure 2.14. Upon receiving the trigger signal the camera starts
integration for the frame, completes the integration, and transfers the information to
the vertical registers and then captures the image is being read out. There is no
delay between the trigger rising edge and the exposure start. The exposure is set by

the trigger pulse duration or by internal exposure register. The number of frames
captured after each trigger pulse can be programmed. This completes the current
trigger cycle and the camera idles until the next trigger pulse.
CAUTION NOTE
The time interval between the trigger pulses must be greater than the combined
exposure and frame time. If the time between the triggers is shorter, the frame readout cycle will be interrupted and part of the frame will be lost.

Fast Synchronized Triggering – Rapid Capture
Fast synchronized triggering (a.k.a. rapid capture) provides the ability to run the
camera in a slave mode, allowing several cameras to be synchronized with an
external master trigger signal. This mode also enables the camera to run close to its
original frame rate. If this mode is enabled, the camera idles and waits for a trigger
signal to come from the selected. Upon receiving the trigger signal, the camera
starts integration until the next trigger is received. Then the information is
transferred to the registers and read out. During this time the next frame is exposed
– Figure 2.15. In this mode the camera exposure can be controlled with the internal
shutter or with the trigger pulse width. If the shutter is not used, the camera
exposure time will be equal to the time between the trigger pulses (trigger period).
If the internal shutter is used the exposure control slider sets the exposure – Figure
2.15. The number of frames captured is set to 1 and cannot be changed.

Double Exposure Triggering
Double exposure allows two events (two images) to be captured in rapid succession
using a single trigger pulse. In this mode, the camera idles and waits for a trigger
signal to come from the selected source. Upon receiving the external trigger signal,
the camera clears the horizontal and vertical registers, and starts integration. There
is NO DELAY between the active trigger edge of the trigger pulse and the
beginning of the integration. Upon receiving the trigger signal the camera starts
integration for the first frame, completes the integration, transfers the information to
the vertical registers and then captures the second image. While capturing the
second image the first one is being read out. After exposing the second image, the
information is transferred to the vertical registers and read out – Figure 2.16. This
completes the current trigger cycle and the camera idles until the next trigger pulse.
In this mode the camera exposure can be controlled with the internal shutter or with
the trigger pulse width. The number of frames captured is set to 2 and cannot be
changed. There is NO DELAY between the frames captured.

time imposes some restrictions for minimum exposure duration in standard and
double triggering modes. The minimum exposure period is camera dependent as
shown below:
B0610 and B0620 – minimum exposure is 2 us,
B1410 and B1610 – minimum exposure is 4 us,

Frame Accumulation Triggering
When the Frame Accumulation triggering mode is enabled, the camera idles and
waits for a trigger signal. Upon receiving the external trigger signal, the camera
clears the horizontal and vertical registers, sends a shutter pulse to clear the pixels
and starts integration – Figure 2.17. Upon receiving the trigger signal the camera
starts integration for the first frame, completes the integration, transfers the
information to the vertical registers and then waits for the next trigger. Upon
receiving the next trigger signal the camera starts integration for the next frame,
completes the integration, transfers the information to the vertical registers and then
waits for the next trigger. The number of triggers used is set by the “Pulses per
Capture” register. After the last trigger has been received the information is being
read out. This completes the current trigger cycle and the camera idles until the next
trigger pulse. In this mode the camera exposure can be controlled with the internal
shutter or with the trigger pulse width.

Asynchronous Triggering
When the Asynchronous triggering mode is enabled, the camera is free running (no
horizontal and vertical flushing prior to trigger). Upon receiving the external trigger
signal, the current CCD timing stops, all camera lines are rapidly flushed, and a new
frame starts – Figure 2.18. This completes the current trigger cycle, the camera free
running and waits for the next trigger pulse. In this mode the camera exposure can
be controlled with the internal shutter or with the trigger pulse width. The time
required for rapid line flush (all charges stored in the vertical registers are cleared)
is camera dependent and if the camera is triggered via CC line, and the camera
exposure is determined by the duration of the CC pulse, the CC pulse duration must
be longer than the rapid flush time, as shown below.

STROBE OUTPUT
The strobe output is used to synchronize an external light source with the camera timing,
and thus to maximize the camera efficiency in low light level conditions. The optimal
strobe signal position is achieved by the positioning of the STROBE pulse, with respect to
the vertical transfer pulse VCCD (end of the frame) - Figure 2.19. BOBCAT supports two
independent strobe signals. Each strobe pulse can be positioned within the entire frame
timing period with a precision 1.0 us. The strobe duration can be seen from 1.0 us to 65535
us with a precision of 1.0us. The internal camera timing has a flag for odd and even frames.
Each strobe can be assigned to every frame, only odd frames, only even frames, or the
strobe can be disabled. The actual strobe signal can be mapped to the corresponding camera
outputs – please refer to the “I/O Control” section.
CAUTION NOTE
During Standard triggering mode the odd/even frame flag resets with each new trigger. In
this case, if the number of frames is set to 1 the strobe will be present only in “Every
Frame” and “Odd Frames”.

GAIN and OFFSET
2.8.1 Analog Domain – manual control
The camera has dual analog signal processors (or Analog Front End – AFE), one
per channel. It features one dual processor, each containing a differential input
sample-and-hold amplifier (SHA), digitally controlled variable gain amplifier
(VGA), black level clamp and a 14-bit ADC. The programmable internal AFE
registers include independent gain and black level adjustment. There are 1024
possible gain levels (gcode 0 to 1023) and 1024 offset (clamp) levels (ocode 0 to
1023). Figure 2.20 shows the relationship between the video signal output level and
gain/offset. Theoretically, the black level should reside at 0 volts and the gain
changes should only lead to increasing the amplitude of the video signal. Since the
camera has two separate video outputs coming out of the CCD, there is always
some offset misbalance between the video outputs. Thus, changing the AFE gain
leads to a change in the offset level and to a further misbalance between the two
video signals. To correct the balance between two signals for a particular gain, the
user should always adjust the offset for each output – refer to the Camera
Configuration section. The overall camera gain can be calculated using formula 2.3,
where Fixed Gain (FG) is user selectable (- 3dB, 0, 3 dB, or 6dB).
VGA Gain [dB] = FG [dB] + 0.0351 x gcode

2.8.2 Digital Domain – manual control
The camera has a built in digital gain and offset control. There are 20 possible
digital gain levels from 1.0x to 3.0x with step of 0.1x, and 1024 offset levels from
(–511, to + 511).
2.8.3 Automatic Gain Control (AGC)
The camera can be set to automatic gain (and exposure) control in order to keep the
same image brightness during changing light conditions. In this mode the user sets
the image brightness (luminance) to be maintained, and the camera adjusts the gain
accordingly. The user can select the average or peak brightness to be maintained.
The camera starts with changing the gain within the preset by the user min-max
limits. If one of the gain limits has been reached, the camera indicates the limit has
been reached and keeps the value until the light condition change. The speed of
convergence (how fast the camera stabilizes after change), can be preset by the user
(four possible options are available). If both modes, automatic exposure and
automatic gain are enabled simultaneously, the camera starts with changing the
exposure first within the preset by the user min-max limits. If one of the exposure
limits has been reached, the camera engages the analog gain, and changes it within
the preset by the user min-max limits. The AGC algorithm samples all pixels for the
entire frame, but the user can select only a portion of the image (AOI) to be used as
a sample collecting region. The camera displays the current luminance, current
exposure and current gain. For auto exposure control refer to Automatic Exposure
Control (AEC) section.

DATA OUTPUT FORMAT
2.9.1 Bit Depth
The internal camera processing of the CCD data is performed in 14 bits. The
camera can output the data in 14, 12, 10 or 8 bit format. During this standard bit
reduction process, the least significant bits are truncated – Figure 2.21.
-
“14-bit” – All original bits D0 (LSB) to D13 (MSB) are used. This mode is
available only for Single Output.
-
“12-bit” – If the 14 bit original camera data is D0 (LSB) to D13 (MSB), and
camera is set to output 12 bit data, the 12 output bits are mapped to D2 (LSB) to
D13 (MSB).
-
“10-bit” – If the 14 bit original camera data is D0 (LSB) to D13 (MSB), and
camera is set to output 10 bit data, the 10 output bits are mapped to D4 (LSB) to
D13 (MSB).
-
“8-bit” – If the 14 bit original camera data is D0 (LSB) to D13 (MSB), and
camera is set to output 8 bit data, the 8 output bits are mapped to D6 (LSB) to
D13 (MSB).

2.9.2 Digital Data Shift
The “Digital Shift” feature allows the user to change the group of bits sent to the
camera output and therefore manipulate the camera brightness. The user can
implement up to 7 bits left or right digital shift. The internal camera processing of
the data is 14 bits. If the camera is set to output 10 bits of data then the four least
significant bits are truncated. In some cases the user may need to convert from 14 to
10 bit by preserving the 4 least significant bits and truncating the 4 most significant
ones – Figure 2.22. Please note that the camera signal-to-noise ratio will be reduced
using the data shift option.

2.9.3 Output Format
BOBCAT camera series supports several out formats, which are based primarily on
the CCD imager used in the camera, and the number of outputs available. For more
information, please refer to Table 2.1.
A.
Single Output Cameras
For the single output cameras (B0610, B1410 and B1610) the user has several
options based on the CDD imager used. For the camera with monochrome imager
the user has only one option – 1 Tap Sequential. If the camera has a color imager
user can select the raw Bayer data output (1 Tap Sequential) or the interpolated
color – 3 Tap RGB.
-
“1 Tap Sequential” – In this mode all pixels (for every line) are sent to one
output (Tap 1) in a sequence, starting with the first and ending with the last (L)
pixel (1, 2, 3, … L-1, L) – Figure 2.23. Each pixel can be 8, 10, 12 or 14 bit
deep.

B.
Dual Output Cameras
For the dual output cameras (B0620, B1620, B1920 and B2520) there are several
options available, since the camera can work in a single or in a dual output mode
and can have a color or monochrome imager. In a single mode (not available in
B2520) operation for the camera with monochrome imager the user has only one
option – 1 Tap Sequential. If the camera has a color imager and is in a single mode,
user can select the raw Bayer data output (1 Tap Sequential) or the interpolated
color – 3 Tap RGB. For Dual mode of operation regardless of imager type (mono or
color) the user has two choices – 2 Tap Sequential or 2 Tap Interleaved. 3 Tap RGB
is not available because of bandwidth limitations for Base Camera Link
-
“2 Tap Sequential” – In this mode all pixels are sent to two outputs (Tap 1 and
Tap2) in the following sequence – Figure 2.24a. Each pixel can be 8, 10 or 12
deep (14 bit output is not available in this mode). This feature is optional, please
contact Imperx for more information.
Tap 1 – starting (for every line) with the pixel 1 and then all pixels in a
sequence (1, 2, 3 … M-1, M) until reaches the middle pixel (if the
CCD has 1000 pixels in one line, the middle pixel M is #500.
Tap 2 – starting (for every line) with the pixel M+1 and then all pixels in a
sequence (M+1, M+2, M+3 …L-1, L) until reaches the last pixel for
the line.

2.12 TEST IMAGE PATTERNS
2.12.1 Test Image patterns
The camera can output several test images, which can be used to verify the
camera’s general performance and connectivity to the frame grabber. This ensures
that all the major modules in the hardware are working properly and that the
connection between the frame grabber and the camera is synchronized – i.e., the
image frameing, output mode, communication rate, etc. are properly configured.
Please note that the test image patterns do not exercise and verify the CCD’s
functionality.
The following test images are available:
- Black – displays black image (value x0000
- Gray – displays an uniform dark gray image (value x2000)
- White – displays an uniform white image (value 3FFF)
- H Ramp Still – displays a stationary horizontal ramp image
- V Ramp Still – displays a stationary vertical ramp image
- H Ramp Move – displays a moving horizontal ramp image
- V Ramp Move – displays a moving vertical ramp image
- Vertical Bars – displays a set of 8 vertical gray bars with different gray levels.
2.12.2 Image Superimposition
The user has the capabilities to superimpose over a live image the following test
patterns. The user can change the brightness of the superimposed image from black
(invisible) to white. Image superimposition is not available during H & V binning.
- “Crosshair” – Crosshair watermark (2 pixels/ 2 lines thickness) indicating the
absolute image center of the image.
- “H & V Lines” – A pair of Horizontal and Vertical lines can be positioned in
the image. The user can enable the lines in horizontal, vertical or both
directions, and to position them at any pixel/line in the image. Since the H & V
lines can be used as a measuring tool, the pixel and line positions are referenced
to the CCD pixels and lines, not to the image pixels and lines. The spacing
between the lines can be displayed in:
1. Pixels - Natively, the spacing between the lines is shown in pixels
2. Metrical units - In addition, the user can use these lines as a measuring
tool. The user can apply a scale coefficient and thus, to calculate the spacing
in linear measuring units (micrometers, millimeters or meters).

Black Level Correction
As was described in the Gain and Offset section, the reference black level on each CCD
output fluctuates around 0V. The AFE offset correction works on the entire image and if
there are noise fluctuations on a line level, the AFE is not capable of correcting them. The
camera has a built in dynamic signal-to-noise correction feature to compensate for this
effect. In the beginning of each line the CCD has several back (masked) columns. The dark
level for each tap is sampled over several of these masked pixels and the average per tap
black level floor is calculated for each frame. The average floor level for each tap is then
subtracted from each incoming pixel (from the corresponding tap) from the next frame.
Tap Balancing
Since the camera has two separate video outputs coming out of the CCD, there is always
some offset misbalance between the video outputs. Thus, changing the AFE gain leads to a
change in the offset level and to a further misbalance between the two video signals. To
correct the balance between two signals at any particular gain, BOBCAT series of cameras
have static and dynamic balancing algorithms implemented in the firmware. The
algorithms compares the black and bright levels of the adjacent pixels around the tap line,
and adjusts the gain and offset for each tap accordingly, until the balance has been reached.
The selection to use static or dynamic balancing depends on the application. Please note,
that if AGC is enabled, it is strongly recommended to use static balancing, because the
dynamic balancing can interfere with the AGC algorithm.
2.14 TRANSFER FUNCTION CORRECTION – USER LUT
The user defined LUT (Lookup Table) feature allows the user to modify and transform the
original video data into any arbitrary value – Figure 2.30. Any 12-bit value can be
transformed into any other 12-bit value. The camera supports two separate lookup tables,
each consisting of 4096 entries, with each entry being 12 bits wide. The LUT is applied to
the entire image unless AOI8 is enabled as “LUT ROI”. In this case the LUT function will
apply only to the selected ROI. The first LUT is factory programmed with a standard
Gamma 0.45. The second LUT is not pre-programmed in the factory. Both LUT’s are
available for modifications, and the user can generate and upload his own custom LUT
using the BOBCAT Configuration software – refer to Appendix B.

2.14.1 Standard Gamma Correction
The image generated by the camera is normally viewed on a CRT (or LCD) display,
which does not have a linear transfer function – i.e., the display brightness is not
linearly proportional to the scene brightness (as captured by the camera). As the
object brightness is lowered, the brightness of the display correspondingly lowers.
At a certain brightness level, the scene brightness decrease does not lead to a
corresponding display brightness decrease. The same is valid if the brightness is
increased. This is because the display has a nonlinear transfer function and a
brightness dynamic range much lower than the camera. The camera has a built-in
transfer function to compensate for this non-linearity, which is called gamma
correction. If enabled, the video signal is transformed by a non-linear function close
to the square root function (0.45 power) – formula 2.4. In the digital domain this is
a nonlinear conversion from 12-bit to 12-bit – Figure 2.31.
Output signal [V] = (input signal [V]) 0.45
(2.4)
Figure 2.31 – Gamma corrected video signal
2.14.2 User Defined LUT
The user can define any 12-bit to 12-bit transformation as a user LUT and can
upload it to the camera using the configuration utility software. The user can
specify a transfer function of their choice to match the camera’s dynamic range to
the scene’s dynamic range. There are no limitations to the profile of the function.
The LUT must include all possible input values (0 to 4095) – Figures 2.32.

2.15 DEFECTIVE PIXEL CORRECTION
A CCD imager is composed of a two-dimensional array of light sensitive pixels. In
general, the majority of the pixels have similar sensitivity. Unfortunately, there are some
pixels which sensitivity deviates from the average pixel sensitivity. A defective pixel is
defined as a pixel whose response deviates by more than 15% from the average response.
In extreme cases these pixels can be stuck ‘black’ or stuck ‘white’ and are non-responsive
to light. There are two major types of pixel defects – “Defective” and “Hot”.
1. ”Defective” – these are pixels which sensitivity deviates more than 15% due to
fluctuations in the CCD manufacturing process. Two type of defective pixels are
possible:
a. “DARK” is defined as a pixel, whose sensitivity is lower than the sensitivity of
the adjacent pixels. In some cases this pixel will have no response (completely
dark).
b. “BRIGHT” is defined as a pixel, whose sensitivity is higher than the sensitivity
of the adjacent pixels. In some cases this pixel will have full response (completely
bright).
2. “Hot” – these are pixel, which in normal camera operation behaves as normal pixel
(the sensitivity is equal to the one of the adjacent pixels), but during long time
integration behaves as a high intensity bright pixel. In some cases this pixel will have
full response (completely bright).
During factory final testing, our manufacturing engineers run a program specially
designed to identify these ‘defective’ and “hot” pixels. The program creates a file which
lists the coordinates (i.e. row and column) of every defective pixel. This file, called the
Defect Pixel Map, is then downloaded into the camera’s non-volatile memory. Users may
wish, however, to create and to upload their own DPM file because of the uniqueness of their
operating environment or camera use. When ‘Defective Pixel Correction’ is enabled, the
camera will compare each pixel’s coordinates with entries in the ‘defect’ map. If a match
is found, then the camera will ‘correct’ the defective pixel. When ‘Hot Pixel Correction’
is enabled, the camera will compare each pixel’s coordinates with entries in the ‘defect’
map. If a match is found, then the camera will ‘correct’ the hot pixel.
“Defective Pixel Correction” and “Hot Pixel Correction” can be independently enabled.
The "Defective/Hot Pixel Map" can be displayed upon user request.

2.16 FLAT FIELD CORRECTION
A CCD imager is composed of a two dimensional array of light sensitive pixels. Each
pixel within the array, however, has its own unique light sensitivity characteristics. Most
of the deviation is due to the difference in the angle of incidence and to charge transport
artifacts. This artifact is called ‘Shading’ and in normal camera operation should be
removed. The process by which a CCD camera is calibrated for shading is known as ‘Flat
Field Correction’. Refer to Figures 2.33a and 2.33b for images acquired before and after
Flat Field Correction. This feature is available as a standard feature only for cameras with
1.0” optical format or bigger.
The BOBCAT series of cameras incorporate a Flat Field Correction mechanism. The Flat
Field Correction mechanism measures the response of each pixel in the CCD array to
illumination and is used to correct for any variation in illumination over the field of the
array. The optical system most likely introduces some variation in the illumination
pattern over the field of the array. The flat field correction process compensates for
uneven illumination, if that illumination is a stable characteristic of each object exposure.
During factory final testing, our manufacturing engineers run a program specially
designed to identify the shading characteristics of the camera. The program creates a Flat
Field Correction file, which contains coefficients describing these shading characteristics.
This file is then downloaded into the camera’s non-volatile memory. When Flat Field
Correction is enabled, the camera will use the Flat Field Correction coefficients to
compensate for the shading effect.
Each Imperx camera is shipped with the Flat Field Correction file that was created for
that camera during factory final testing. Users may wish, however, to create their own
Flat Field Correction file because of the uniqueness of their operating environment (i.e.
lens, F-stop, lighting, etc.). Therefore, Imperx provides a Flat Field Correction utility that
allows users to generate a Flat Field Correction file. This file can then be downloaded
into the camera. While creating the Flat Field Correction file, it is necessary to illuminate
the CCD with a light pattern that is as representative of the background illumination as
possible. This illumination should be bright enough, or the exposure made long enough,
so that the CCD pixels signals are at least 25 percent of full scale (for 12 bit mode the
level should be at least 1000 ADUs).

2.17 NEGATIVE IMAGE
When operating in the negative image mode, the value of each pixel is inverted. The
resultant image appears negative – Figure 2.34. This feature could be useful if the camera
receives a negative image (i.e. image from microfilms, prints or slides). In this mode the
image has a normal vertical and horizontal orientation and full resolution. This feature is
available in both single and dual output modes.

2.18.1 Status LED
The camera has a dual red-green LED, located on the back panel. The LED color
and light patter indicate the camera status and mode of operation:
•
GREEN is steady ON – Normal operation. The user is expected to see a normal
image coming out of the camera.
•
GREEN blinks with frequency ~ 0.5 Hz – indicates triggering mode.
•
GREEN blinks with frequency ~ 2.0 Hz – indicates programmable integration
(line, frame or both) mode.
•
YELLOW is steady ON – Test mode. The user is expected to see one of the test
patterns.
•
YELLOW blinks with frequency ~ 0.5 Hz – the camera is in AGC/AEC mode.
In this mode changing the shutter slider will not affect the image luminance.
•
YELLOW blinks with frequency ~ 2.0 Hz – the camera is in external H or V
sync mode. The camera timing will be slaved to the external pulses. Changing
programmable integration sliders will not affect the image luminance
•
RED is steady ON – RS232 communication error or firmware load error. Repower the camera and load the factory settings. If the condition is still present,
please contact the factory for RMA.
•
LED is OFF – Power not present error. The camera has no power or indicates a
camera power supply failure. A faulty external AC adapter could also cause this.
To restore the camera operation, re-power the camera and load the factory
settings. If the LED is still “OFF”, please contact the factory for RMA.

3.1
OVERVIEW
The camera has built-in several basic image processing functions. More functions will be
added later. Please contact Imperx for more information.
3.2
IMAGE ENHANCEMENT
In many imaging applications the user will have a dark object on a bright background,
many dark and bright spots or shadows, or the light will not be sufficient, so the resulting
image will have a low contrast, and/or a vary low dynamic range. To improve the image
quality in such conditions, BOBCAT offers a set of image enhancing features –
thresholding and multi-point image correction. The processing function is applied to the
entire image unless AOI8 is enabled as “Processing ROI”. In this case the processing
function will apply only to the selected ROI.
3.2.1 Threshold Operation
In many applications the binary images are much simpler to analyze that the
original gray scale one. The process, which converts the regular gray scale image
to binary, is called “Thresholding”. Thresholding is a special case of intensity
quantization (binarisation) where the image can be segmented into foreground and
background regions, having only two gray scale levels “white” and “black”.
Selecting the threshold value is very critical for the binary image quality, and it is
to a great extend scene dependent. If a threshold level is chosen correctly, this will
produce a well-defined boundary of the object, which is essential. In some cases it
is desirable if part of the image is binary and some is grayscale image. The
camera has built in four thresholding modes:
3.2.1.1 Single Threshold Binary
If the image is a high contrast scene and has well defined bright and dark
regions a simple binarisation technique can be used for thresholding –
Formula 3.1. The binary image output is converted to “white” for all gray
level values higher or equal to the selected threshold point X1, and to
“black” for all gray levels lower than X1. The user can set the optimal
threshold value. Figure 3.1 shows the original and the processed image
with single threshold.

3.2.1.2 Dual Threshold Binary
If the image has a low contrast and does not have well defined dark and
bright regions, the simple threshold operation does not yield good results.
In such cases a dual (known also as interval or window) thresholding
technique has to be implemented – Formula 3.2. The binary image output
is converted to “white” for all gray level values between the selected
threshold interval X1 and X2, and to “black” for all gray levels outside
(X1, X2) interval. The user can set the optimum X1 (Low) and X2 (High)
threshold values, please note that X2 > X1. Figure 3.2 shows the original a
processed image after a dual threshold operation.

3.2.1.3 Dual Threshold with Gray Scale
In some low contrast imaging applications, the simple threshold operation
along with a superimposed gray scale image might yield a good result. In
such cases a dual thresholding technique with a gray scale has to be
implemented – Formula 3.3. The image output is a gray scale image for all
gray level values between the selected threshold interval X1 and X2,
“black” for all gray levels lower than X1, and “white” for any gray levels
higher than X2. The user can set the optimum X1 (Low) and X2 (High)
threshold values, please note that X2 > X1. The image gray scale range is
only from values X1 to X2.

if (input signal ≤ X1)

3.2.1.4 Dual Threshold with Gray Scale Stretch
In some low contrast applications, the threshold operation along with a
gray scale stretch might yield a good result – Figure 3.3. This is similar to
dual threshold with a gray scale, but the image gray scale is digitally
stretched to full 12 bit gray scale – Formula 3.4. The user can set the
optimum X1 (Low) and X2 (High) threshold values, note that X2 > X1.
Output signal => “BLACK”
if (input signal ≤ X1)
“Full Gray Scale” if (X1 < input signal < X2)

function (TF), which results in the suppression or enhancement of certain image

regions. The original camera transfer function is linear and maps the data 1:1. The
new (corrected) transfer function has one or two sets of variable (X, Y) and based
on the relation between the variables a correction of certain image regions can be
achieved. The camera has two built in correction modes.
3.2.2.1 Single Point Correction
Output signal
The simplest image enhancement can be achieved by a linear modification
of the original transfer function. If the image brightness is weighted
towards a particular region (dark or bright), this region needs to be
suppressed, and the less present (the flat) region needs to be enhanced.
The range of the correction is determined by the location of the break
point (X1, Y1) – Figure 3.4. This point (X1, Y1) divides the camera
transfer function into two regions (two lines). The slope of these lines (the
angle between the X axis and the line) determines the power of the
correction. If the angle is less than 45O degrees, the grayscale range will be
suppressed. If the angle is more than 45O degrees, the grayscale range will
be enhanced. The user can set the optimum (X1, Y1) values.

If the image brightness is weighted towards two particular region – dark

multi point correction will produce much better results compare to the
single point correction. The range of the correction is determined by the
location of a pair of the break point (X1, Y1) and (X2, Y2) – Figure 3.5a.
The camera transfer function is divided into three regions (three lines),
which allows multiple grayscale regions to be corrected independent of
each other. If the angle is less than 45O degrees, the grayscale range will be

range will be reversed. Curve TF 1 enhances the dark image regions and

4.1
OVERVIEW
The Bobcat series of cameras are highly programmable and flexible. All of the
cameras resources (internal registers, video amplifiers and parameter FLASH) can
be controlled by the user. The user communicates with the camera using a simple,
register-based, command protocol via the Camera Link’s serial interface. The
interface is bi-directional with the user issuing ‘commands’ to the camera and the
camera issuing ‘responses’ (either status or info) to the user. The entire camera
registers and resources can be configured and monitored by the user. The
camera’s parameters can be programmed using the Bobcat Configurator graphical
user interface.
4.2
CAMERA CONFIGURATION
4.2.1 Configuration Memory – parameter FLASH
The camera has a built-in configuration memory divided into 4 segments: ‘workspace’, ‘factory-space’, ‘user-space #1’ and ‘user-space #2’. The ‘work-space’
segment contains the current camera settings while the camera is powered-up and
operational. All camera registers are located in this space. These registers can be
programmed and retrieved via commands issued by the user. The workspace is
RAM based and upon power down all camera registers are cleared. The ‘factoryspace’ segment is ROM based, write protected and contains the default camera
settings. This space is available for read operations only. The ‘user-space #1’ and
‘user-space #2’ are non-volatile, FLASH based and used to store two user defined
configurations. Upon power up, the camera firmware loads the work-space
registers from the factory-space, user-space #1 or user-space #2 as determined by
a ‘boot control’ register located in the configuration memory. The ‘boot control’
register can be programmed by the user (refer to Camera Configuration Section).
The user can, at any time, instruct the camera to loads its workspace with the
contents of either the ‘factory-space’, ‘user-space #1’ or ‘user-space #2’.
Similarly, the user can instruct the camera to save the current workspace settings
into either the ‘user-space #1’ or ‘user-space #2’.
The non-volatile parameter FLASH memory also contains Defective Pixel Map,
Hot Pixel Map, Flat Field Correction Coefficients, LUT 1 and LUT 2, which can
be loaded to the camera internal memory upon enabling the corresponding camera
feature. The user can create its own DPM, HPM, FFCC, and LUT tables and
upload them to the parameter FLASH using the Bobcat Configurator graphical
user interface.

4.2.3 Camera Serial Protocol
In order to access the camera registers and resources a sequence of bytes needs to
be transmitted to the camera via the Camera Link serial interface. This is an
RS232, asynchronous, full-duplex, serial protocol, with 8 data bits, 1 stop bit, and
no parity – Figure 3.1. The default baud rate is configurable (9600, 19200, 38400,
57600 and 115200 – default).
Figure 3.1 – Serial protocol format
Each camera control register can be updated independently. In terms of the serial
protocol, all registers are defined as 16-bit address (hex format), and 32-bit data
(hex format). Camera registers using less than 32-bits in width must be padded
with ‘0’s on writes, and unused bites are ignored on reads. Register data is always
“packed low” within 32-bit data words for registers defined less than 32-bits.
There is a latency delay for each command due to command execution and data
transmission over the serial port. This latency varies from command to command
because of resource location and command response length.
4.2.3.1 Write Operation
In order to write to any given camera register, a sequence of 7 bytes should be
sent to the camera. If there is no error the camera returns one byte
acknowledge for the write command <Ack> - Figure 3.2. If there is an error
the camera returns two bytes not-acknowledge for the write command – the
first byte is <Nac> <Err>, the second is the error code – Figure 3.3a,b:

CAMERA CONFIGURATION REGISTER DESCRIPTION
4.3.1 Startup Procedure
Upon power on or receipt of an ‘SW_Reset’ command, the camera performs the
following steps:
1. Boot loader checks Program FLASH memory for a valid Firmware image and
loads it into the FPGA.
2. The camera reads the ‘Boot From’ register from the parameter FLASH and
loads its workspace from one of the configuration spaces as determined by the
‘Boot From’ data. The available configuration spaces are: ‘Factory…’,
‘User #1…’, ‘User #2…’
3. The camera is initialized and ready to accept user commands.
4.3.2 Saving and Restoring Settings
Operational settings for the camera may be stored for later retrieval in its nonvolatile memory. Three separate configuration spaces exist for storing these
settings: ‘factory’ space, ‘user #1’ space and ‘user #2’ space. The factory space is
pre-programmed by factory personnel during the manufacturing process. This
space is write protected and cannot be altered by the user. Two user spaces are
also provided allowing the user to store his/her own preferences. The camera can
be commanded to load its internal workspace, from either of the three
configuration spaces, at any time. The user can also define from which space the
camera should automatically load itself following a power cycle or receipt of a
reset (‘SW_Reset’) command.
4.3.2.1 Boot From
This register determines which configuration space (factory, user#1 or user
#2) should be loaded into the camera following a power cycle or reset
(‘SW_Reset’) command. Upon a power cycle or reset, the camera reads the
‘boot from’ value from non-volatile memory and loads the appropriate
configuration space.

OVERVIEW
Camera configuration utility software and Bobcat Camera Configurator (CamConfig) are
provided with each camera. After installing the program, the user can program the
camera, change its settings and save the settings in a file or in the camera. The
configuration utility includes an interactive help file, which will guide you through the
camera setup.
5.2
DISCOVERY PROCEDURE
Often times, multiple frame grabbers and cameras may be installed into a computer at the
same time. The CamConfig utility provides an intelligent, automated method of
‘discovering’ and ‘searching’ all available UART components in your PC and allowing
the user to select the one that is connected to Bobcat camera. Bobcat search engine is not
only finding the CamLink DLL port but also looking for any available COM port
installed on the PC as well. It will then communicate with each port (.DLL and COM)
and attempt to query the attached camera. If it finds an attached Imperx Bobcat camera, it
will read the ‘camera type’ information from the camera. Bobcat camera name will be
displayed in the list box, which includes all DLLs, ports and cameras that it discovered.
The user can then select the DLL/port/camera, of interest, by highlighting the entry and
clicking on the ‘OK’ button. Clicking on the ‘Rescan Ports’ button causes the above
discovery procedure to be repeated. Please note the frame grabber has to be Camera Link
v1.0 (or later) compliant.

GRAPHICAL USER INTERFACE
After having selected the desired camera, the main Bobcat CamConfig dialog will appear –
Figure 5.2. The Graphical User Interface (GUI) is very intuitive and self-explanatory. The
basic features are:
1. Compact Design – small 140x400 (pixels) save space when user display image and
control at the same time
2. Real Time Data – updates camera inform in real time while camera is working. Gives
quick and general information about camera configuration status.
3. Dockable Windows – all configuration windows (Gain, AOI, Trigger…) can be
separated and “docked” in the main GUI with just one click.
4. Configurable – user can customize the main menu by selecting the sub windows and
also memorize the last setting.
Figure 5.2 – CamConfig GUI
The configuration utility includes an interactive help file, which will guide you through the
GUI controls and camera settings. On the main window the user can see useful camera

information – Current Image Size (Size), Number of Frame per second (FPS), the Frame
Time (FTM), Exposure Time (EXP) and Temperature of the CCD sensor (TMP).
Additional information can be obtained by clicking on the buttons shown in the CamConfig
window, such as Video Amp, I/O Control, Trigger, etc. The bottom of the main utility
window is camera name and status of Cam-link connection. If the connection between the
camera and the computer is lost a red cross will appear above the connection icon.
5.4
MAIN GUI MENU
All panels in the Bobcat CamConfig share the same general control options and menus for
“File”, “View” and “Help” – Figure 5.3.
Figure 5.3 – Main Menu
Run Application:
Select and starts other executable file (Frame-Grabber application,
etc.…) that user normally uses. CamConfig will remember the path
of last executable file that you used, so the next time when you start
the application without type-in location.
Load From:
Loads the camera registers from a saved configuration space: File,
Workspace, Factory Space, User Space #1 or User Space #2.
1. File – loads the camera registers from a saved configuration file
2. Workspace – updates the GUI with the current camera
workspace settings
3. Factory – loads the camera registers with the original (factory)
settings.
4. User Space #1 – loads the camera registers with a saved camera
settings in the user space 1.
5. User Space #2 – loads the camera registers with a saved camera
settings in the user space 2.

Save To:
Saves the camera registers to File, User Space #1 or User Space #2.
Factory Space is disabled for regular users and it is available only for
manufacturing technicians.
1. File – saves the current camera settings to a configuration file
2. Factory Space – saves the current camera settings to the camera
Factory space. This is restricted command and is disabled for
regular users.
3. User Space #1 – saves the current camera settings to the camera
User space 1.
4. User Space #2 – saves the current camera settings to the camera
User space 2.
Boot:
This menu selects the ‘Boot From’ source. Upon power up, the
camera will load its registers from the selected ‘Boot From’ source:
Factory, User #1 or User #2. Bobcat camera will be release with
‘Factory” Setting and user can save and boot camera with their own
configurable features.
DPM:
Defect Pixel Map – When selected, the DPM window will show
defected pixels location. The defective pixel map is stored in the
camera’s non-volatile memory and read out when running bad pixel
correction – Figure 5.4. Defected pixels are categorized as:
Figure 5.4 – Defective pixel map
1. Dead Pixels – pixels with sensitivity that deviates more than
15% due to fluctuations in the CCD manufacturing process.

2. Hot Pixels – pixels that during normal camera operation are
normal, but in long integration modes (programmable frame
time) behave as high-intensity bright pixels.
Terminal:
The user can display two submenus: Command Terminal and
Download Terminal.
1. Command Terminal – shows information about all the
commands sent to or received from the camera. User can type in
Bobcat command directly in the text box provided (refer to
chapter 4 for command structure syntax) – Figure 5.5. The
“Disable Polling” check box will turn on/off the polling
commands (such as Frame Time, Exposure time, Frame Rate and
Sensor Temperature) in the dialog windows. The user can change
the polling time by entering the desired number in the window. If
for some reason the camera returns an error, when command was
sent to the camera, the GUI will respond with a pop-up window
displaying an error message. The user has option to disable the
error checking by enabling the “Disable Error Checking” box.
Figure 5.5 – Command terminal

PARAMETER WINDOWS
Bobcat Cameras have many features that can easily be programmed using the Bobcat
graphical user interface (GUI) or via simple register commands using the Command
Terminal. The main parameter windows are described below.
5.7.1 Video Amp
Video Amp window allows the user to adjust the Analog or Digital gain and offset.
Manual entry and sliders are available for adjusting the individual parameters –
Figure 5.10.
Figure 5.10 – Video Amp parameter window
Analog:
The user can set the desired analog gain (0 to 36 dB, 1024
discrete values) and offset (0 to 1023, 1 step increment) for each
channel via the sliders or by entering the desired values. “Link
Gain” and “Link Offset” links the corresponding channels
together (dual tap camera only), and the gain or offset difference
between them will be preserved.
Pre Amp Gain: The user can select the preamplifier gain for the camera (the
same for both channels). 4 options are possible -3 dB, 0, +3 dB,
and +6 dB. The default Pre Amp Gain value is camera dependent
and it is set for the best camera performance.

Boca Raton, FL 33487
+1 (561) 989-0006
The user can map each of the camera inputs CC1, CC2, IN1 or
IN2 to all available internal input signals. 5 signals are available
for mapping. For each input the user can set the signal level to
active “High” or active “Low”.
1. Computer trigger – maps CC1 or CC2 to the internal (CC)
computer trigger input.
2. External Trigger – maps IN1 or IN2 to the external computer
trigger input.
3. Exposure control – provides an external exposure control
signal. For proper operation set the “Exposure Control
Register” to “External”.
4. H-Sync – synchronizes the camera line timing to the external
pulse. A continuous trail of pulses (one for every line) must
be provided. The camera uses only the pulse edge, but the
duration should be as short as possible. Min. duration - 50 ns.
5. V-Sync – synchronizes the camera frame timing to the
external pulse. A continuous trail of pulses (one for each
frame) must be provided. The camera uses only the pulse
edge, but the duration should be as short as possible. Min.

Figure 5.12. Four control panels are associated with this feature: “Settings”,
“Acquisition Control”, “Exposure control” and “Strobe Control”.
Figure 5.12 – Trigger parameter window
Settings:
Trigger in – selects the active triggering input signal. The
selected trigger signal must be mapped to the corresponding
camera input.
1. Off – the camera is in free-running mode.
2. External – the camera expects a trigger signal coming from
IN1 or IN2 inputs.
3. Pulse Gen – the camera expects a trigger signal coming from
the internal pulse generator.
4. CC – the camera expects a signal coming from CC1 or CC2
inputs.
Mode – selects the desired triggering mode:
1. Standard – in this mode the camera exposes, reads-out the
selected number of frames and waits for the next trigger
signal. In this mode the maximum camera frame rate is LESS
than the free-running one.
2. Fast – in this mode the camera exposes then next frame while
reading the previous. This mode provides the ability to
trigger the camera with its original (free-running) frame rate.
3. Double – this mode is designed for capture fast processes
with short exposure times, and is commonly used in particle

velocity measurement. It is identical to the Standard mode
but, the camera will capture only 2 frames after each trigger
signal. There is no delay between the frames
4. Frame Accumulation – in this mode, after each trigger signal
the camera starts integration then transfers the information to
the vertical registers and then waits for the next trigger. After
the last trigger has been received the information is being
read out.
5. Asynchronous – in this mode the camera is free running prior
to the trigger. When the trigger is applied, it resets the CCD
timing, flushes the remaining lines and starts the integration.
Trigger Edge – the user can select the active triggering edge:
1. Rising – the rising edge is used for triggering.
2. Falling – the falling edge is used for triggering.
Trigger Overlap – the user can select how to handle the next
trigger pulse if arrives while the previous triggering cycle is in
process:
1. Ignore – the next rigger will be ignored, and the camera will
continue its present operation.
2. Accept – the next trigger will be used.
3. Accept after Exposure – the next rigger will be ignored while
the camera is exposing the image.
De-bounce – the trigger inputs are de-bounced to prevent
multiple triggering from ringing triggering pulses. The user has
four choices of de-bounce interval:
1. Off – No De-bounce.
2. 0.1 ms – 100 us de-bounce interval (by default).
3. 1.0 ms – 1 ms de-bounce interval.
4. 10.0 ms – 10 ms de-bounce interval.

INTRODUCTION
The BobCat series of GigE Vision cameras are fully compliant with the Gen<i>Cam
standard. The cameras include an embedded camera description file ( XML ) that contains
all of the information required to automatically map a camera’s features to its internal
registers. The Gen<i>Cam standard defines the syntax and semantics of the camera
description file. It also defines a mechanism for the user to configure the camera by
reading/writing the camera registers associated with the features.
The camera description file ( XML ) contains a set of nodes where each node represents a
feature of the camera. Each node has a set of attributes that define the feature including a
description, type ( ie. integer, boolean, etc. ), register address, minimum value, maximum
value, increment, etc. All of this information is contained in the XML file. The XML file is
transferred from the camera to the host application when a connection is first established.
The host application then parses the XML file and presents the user with a “node tree’
representation.
The BobCat series of cameras include a full-featured host application, called PureGEV,
which allows the user to connect to a camera, view/save images from the camera and
control its features via a “node tree” user interface representation.. Please refer to the
PureGEV Quick Start Guide for details on how to install and use the PureGEV application.
A “node tree” is a tabular list of all of the camera features ( that were described in the XML
file ). The user can control a feature by simply clicking on it with the mouse and editing the
field. Some features provide drop down menu lists, while others support direct data entry.
Features that are read-only ( ie. status indicators ) are de-highlighted and un-editable. Some
features depend on the state of other features. For example, the GainAutoBalance is only
active if the SensorDigitizationTaps is equal to Two. Some features are locked while image
streaming is active. For example, the PixelFormat feature can only be changed while
images are not be streamed.
The following tables illustrate the node tree as it is displayed by the PureGEV application.
For a detailed description of the features, please refer to Chapter 2.

B.1
OVERVIEW
The Lookup Table file can be created using any standard ASCII text editor or by
using Microsoft Excel. Additionally, any spreadsheet or mathematical program
capable of generating a comma delimited (.csv) file can be used.
B.2
USING AN ASCII TEXT EDITOR
A custom LUT (lookup table) can be prepared using any ASCII text editor, such as
“Notepad” or similar. Alternatively, any spreadsheet program (i.e. Microsoft Excel)
can be used by converting the spreadsheet into a comma delimited (.csv) file. In
either case, the file must be renamed to include the .lut extension. The .lut file has
two main sections: a header and a table. The ‘header’ section is a free text area of
up to 256 ASCII characters. Each line of the header section must be terminated in a
comma. The ‘table’ section of the file contains an array of 4096 lines with each line
containing an input value followed by a comma and an output value. The input
values represent incoming pixels and the output values represent what each
incoming pixel should be converted into as an output pixel.
The format of the .LUT file is as follows:
-- Look Up Table input file example,
-- lines beginning with two dashes are comments,
-- and are ignored by parser,
:Header,
-- this is the text that will get displayed with a 'glh' command,
Function is 'Negative Image',

USING MICROSOFT EXCEL
The .LUT file can be created in Excel as follows:
1 - create the spreadsheet as shown below (note that 4096 rows are required in the
table).
2 - add the necessary equations into the output cells to generate the transfer function
required.
3 - save the file as a .csv (comma delimited format).
4 - rename the .csv file to an extension of .lut.

C.1
OVERVIEW
The Defective Pixel Map (DPM) and Hot Pixel Map (HPM) are provided with each
camera. If the user wants to create its own DPM or HPM file, he/she can use any standard
ASCII text editor or Microsoft Excel. Additionally, any spreadsheet or mathematical
program capable of generating a comma delimited (.csv) file can be used.
C.2
USING AN ASCII TEXT EDITOR
A custom Defective Pixel Map (DPM) and Hot Pixel Map (HPM) can be prepared using
any ASCII text editor, such as “Notepad” or similar. The file must have a .dpm extension
for DPM map and .hpm extension for HPM. The .dpm (or .hpm) file has two main sections:
a header and a table. The ‘header’ section is a free text area of up to 256 ASCII characters.
Each line of the header section must be terminated in a comma. The ‘table’ section of the
file contains an array of lines with each line containing an X (pixel number) value followed
by a comma and a Y (line number) value. All pixels are listed in the DPM (or HPM) in
order of increasing Y location. If the Y location is identical, the listing is in order of
increasing X location. After editing save each file with the appropriate file extension. The
maximum number of pixels in the DMP list is 128, and in HPM list is 1024.
Here is a simple example how to create a DPM. Create the DPM file with extension .dpm
using “Notepad” or any other editing software. Locate the defective pixels in the camera
and enter them in order starting with the smallest pixel number of the line number first. The
file looks like this:
-- Defective Pixel Map,
-- Date: 7/21/2009,
-- Model#: ICL-B0610M,
-- Serial#: 060380,
: Table,
-- Column(X),Row(Y)
4,1
588,1
78,5
82,27
405,300
Note.
In this example the first table entry is pixel 4 from line 1, the next entry is pixel 588 from
line 1, and the next entry is pixel 78 from line 5 and so on.

E.1
OVERVIEW
Bobcat Camera series supports user FirmWare (FW) and Workspace registers upgrade,
along with a custom DPC, HPC, FFC and LUT tables upload. The upload utility software is
provided as a part of CamConfig GUI, shipped with each camera. After installing the
program, the user has access to a ‘download’ utility window, which allows the user to
download newly released firmware or other files into the camera’s non-volatile memory.
To receive the latest FW and RGS files, please contact Imperx. The user Application
Firmware file normally is called “ICL_XXXXX_RU_ABC.rpd” where “XXXXX”
represents the camera type and “ABC” represents the version number. The Factory Space
upgrade file is normally called “ICL_ YYYYY _RU_RA.rgs” where “YYYYY” represents
the camera type and “A” represents the version number.
E.2
BOBCAT UPGRADE
The user can select to upload either new Camera Firmware, Camera Factory Register
Space, a Lookup Table, a Defect Pixels Correction table, a Hot Pixels Correction table or a
Flat Field Correction file by selecting the appropriate path/filename of the file can be
entered manually into the edit box or browsed to by clicking on the ‘…’ button. Clicking
on the ‘Load File…’ button begins the download process. The user must be familiar with
the entire procedure and must follow it precisely. To start a Bobcat upgrade, follow the
described steps:
1. Start Application Bobcat CamConfig go to Main Menu and from submenu “Load
From…” select “Factory Space”. Wait until camera is initialized.
2. Go to Main Menu and from submenu “Terminal”, select Download Terminal.
3. When “Download Terminal” is opened, from File Type, you have to select what file
you want to upload to the Camera: Application Firmware Image (rpd), Factory Space
(rgs) file), DPC, HPC, FFC or LUT – Figure E.1.
4. DPC, HPC, FFC and LUT Upgrade: When you select the appropriate file for this
particular camera you have to press button “Load File” and wait to finish the process of

CAUTION NOTE
1.
It is strongly recommended that you DO NOT USE any other communication
software to upgrade the camera FW, RGS, DPC, HPC, FFC and LUT files.
2.
If the user selects to upgrade camera firmware and camera factory register
space, the camera firmware must be upgraded first.
3.
During camera RGS or FW upgrade the camera power must be on all the time,
and the process must not be interrupted. If the camera is disconnected or the
process canceled, this will result in a user application firmware corruption. If
such event occurs start the upload process again until completion. If the upgrade
process cannot be completed, the camera will power with the default Factory
Firmware so you can start the upgrade process again. If you need more

During DPC, HPC, FFC or LUT upgrade the camera power must be on all the
time, and the process must not be interrupted. If the camera is disconnected or
the process canceled, start the upload process again until completion. If the
upgrade process cannot be completed, the corresponding camera function will
not work. This will not affect the overall camera performance, so you can start
the upgrade process again. If you need more information, please contact Imperx.
