Network adapter: the default value is broadcast, i.e. the driver searches for cameras
through each enabled network adapter. If a specific adapter is selected, the driver
searches for cameras only through it.
Network performance: it’s a delay added to the data exchange between the cameras
and the computer. If there is traffic on your local network, then move the slider to “More
reliable” to avoid loss of data during the communication
Network Connections: click this button to open the “Network Connections” control panel
applet and configure the network adapter’s IP address.
Ethernet Datagram size: see one of the topics below.
4.2. Configuring the Y camera IP address
Y cameras are delivered with a specific IP address. If the address is not compatible with
your network parameters, the camera is not able to establish a communication with the
computer through the network. To set the IP address for the first time, please follow the
instructions below.
•
Connect the Y camera to the computer through the USB 2.0 cable.
•
From the Motion Studio program group, select Tools and run the “Network
Configuration”.

utility.
•
Turn off the camera and turn it on. The new IP address is stored and will be used by
the camera in Giga Ethernet communication.
NOTE #1: the computer network adapter may not have a specific IP address because it’s
assigned by the DHCP. If there is any problem for the software to detect the camera, it’s
better to assign a specific IP address also to the computer adapter. To do that, open the
“Network Connections” window and select the Properties of the network adapter. Select
the “Internet Protocol (TCP/IP)” and click the “Properties…” button. Select the “Use the
following IP address” option and set the IP address and subnet mask values.
NOTE #2: if the camera IP address is not compatible with the adapter’s IP address, the
camera will be listed with a yellow exclamation mark. If you try to open a session the
software will not be able to grab images from the camera and an error message will
appear.

4.4. Forbidden IP addresses
The following IP addresses are not allowed to be configured on the camera.
•
Loopback addresses: from 127.0.0.0 to 127.255.255.255.
•
Multicast addresses: from 224.0.0.0 to 239.255.255.255.
The following combinations of IP address and subnet mask are not allowed as well:
•
Broadcast addresses: (IP_subnet_mask | IP_address) = 255.255.255.255.
•
Sub-network addresses: (~IP_subnet_mask & IP_address) = 0.0.0.0
The IP address 0.0.0.0 is allowed. In that case the camera is supposed to connect to a
DHCP server and receive a valid IP address.

4.5. Large datagram size (Jumbo packets)
Some Giga-Ethernet network adapters are able to send and receive large data packets.
The usual datagram size is 1500 bytes. Large datagram packets, called Jumbo packets,
are up to 9000 bytes.
If both the camera and the adapter can use jumbo packets, the transfer speed is
increased. To activate jumbo packets, do the following.

4.6. Configuring the Windows Firewall
All the cameras that support gigabit Ethernet communication may have issues if the
Windows Firewall is installed. They communicate through the UDP network protocol and
need to open listening ports to receive the images.
In most of the cases, the windows firewall shouldn’t be disabled, Motion Studio should be
added to the list of the allowed programs and some other parameters should be
configured in the firewall (especially with HG cameras).
4.6.1. How to add Motion Studio to the list of allowed programs.
When an Ethernet camera is operated for the first time, the Windows firewall detects the
attempt to communicate through the network and tries to block it. The message below
appears
The software will be allowed to communicate through the network if both the private and
public options are selected. Then click the “Allow access” button.
If the User Account Control (UAC) is disabled or you don’t check both the options, you
may still allow the communication through the firewall.
•
From the control panel, start the Windows Firewall and select “Allow a program or
feature through Windows Firewall”.
•
Scroll the list and make sure that “Motion Studio” is in and all the check boxes are
selected (see below).

4.6.2. How to allow incoming echo requests (HG cameras)
HG cameras support the ICMP (Internet Control message Protocol). The cameras send a
“ping” to the connected computer to check if the communication is still available. If the
firewall blocks such packets the communication between the camera and the computer
fails. For this reason, adding Motion Studio to the list of allowed programs is not enough.
In addition, ICMP echo requests should be allowed.
4.6.2.1. Windows XP
To detect if ICMP echo requests are allowed, open the Windows firewall and select the
“Advanced Tab”.
Click the ICMP settings and make sure that the “Allow incoming echo requests” option is
selected.

4.7. Configuring the X camera IP address
When a MotionPro X camera is powered up, it does not have an IP address. Without a
valid IP address the camera can be enumerated, but some parameters, such as camera
model, serial number, etc. cannot be read. The Configuration utility enumerates all the
IDT GE cameras and shows each camera’s IP address or “none”. A camera without a
valid IP address is listed with a red spot on the icon.
For each camera the user may click the “Edit IP Address…” button. If the camera has an
IP address, it may be edited, and otherwise the application “suggests” a value. The user

5.9. Lookup Table
The lookup table (LUT) transformations are basic image-processing functions that you
can use to improve the contrast and the brightness of an image by modifying the dynamic
intensity of region with poor contrast. LUT transformations can highlight details in areas
containing significant information, at the expense of other areas.
A LUT transformation converts input gray-level or color values (8, 10 or 12 bit) into other
gray-level or color values. The transfer function has an intended effect on the brightness
and contrast of the image. Each input value is transformed into a new value by a transfer
function
Output value = F (input value)
Where F is a linear or nonlinear, continuous or discontinuous transfer function defined
over the interval [0, max]. In case of an 8-bit image, a LUT is a table of 256 elements.
Each element of the array represents an input value. Its content indicates the output
value.

SSD Options
Os cameras are equipped with 8 GB RAM (DDR) and onboard solid state disk (256 or
512 GB). The images may be recorded into RAM and/or SSD in the modes listed below.
OFF: the SSD is not used and the camera acquires images in the DDR like any other IDT
camera without SSD.
Backup: the DDR is used as a temporary buffer. The images are acquired in the DDR
and, when recording is done, the images are transferred to the SSD asynchronously. The
camera can record at any frame rate but the maximum number of frames that can be
recorded in each acquisition is limited by the DDR size.
Streaming: In SSD streaming mode, the DDR is used as a temporary buffer. The images
are acquired in the DDR and synchronously transferred to the SSD. Since the write to
disk speed (in frames per second) is fixed and the write to DDR speed is configurable, the
maximum number of frames that can be recorded depends on the difference between
those two numbers. The “Streaming fps” is the frame rate that corresponds to the write to
disk speed.
If the frame rate is lower than streaming fps, the max number of frames that can be
acquired is limited by the SSD size.
If the frame rate is larger than the streaming fps, the max number of frames is variable
and it’s calculated assuming that the record mode is normal. If the record mode is circular
and you wait too long before triggering, you may receive a disk overrun error message.
Mission: in mission mode, the DDR is used as a temporary buffer. For more information,
see the topic below.

SSD mission mode
The mission mode has been designed to acquire images when the camera is
disconnected from the computer. The SSD may be divided into segments, called steps;
each step may have different parameters such as exposure, frame rate, region of interest.
Each step is recorded in normal mode and the recording start may be automatic or
generated by the trigger.
The picture below shows the interface.
Steps in flash memory
Steps acquired in SSD
To configure the camera in mission mode:
•
Click “Reset Steps” to clear the upper list.
•
Click “Add step” as many times as the required number of steps.
•
Edit the parameters by clicking on the corresponding field in the list. If a step need to
be automatically executed after the previous one, select “Auto advance” in the “Action
at end” column of the previous step, otherwise, select “Stop”.
•
Select the “Execute at next camera power cycle” to enable the execution of the
mission when the camera is powered up.
•
Click “Write to camera”
•
Exit the program. The next time the camera will be power cycled the steps will be
automatically executed and the image stored in the SSD. Once the mission is
executed once, the camera may be power cycled more times, but the images will not
be overwritten.
To display images acquired during the mission:
•

Advanced Sync/Trigger Configuration
Trigger In
Y and N cameras can enforce a minimum time that the trigger input must remain
continuously at its active level before it recognizes a valid trigger. This parameter is called
“Debounce” and can be used to reject noise pulses on the trigger input, or to de-bounce
mechanical contacts used as trigger sources.
After it recognizes a valid trigger pulse, the camera can wait for a few microseconds
before issuing the trigger. This parameter is called “Delay”.
Sync In
The “Debounce” and “Delay” parameters can be applied to the sync in source as well
(see above). If an external sync source is connected to the camera, the software is able
to detect the rate and the pulse width of the signal. If the user sets the frame sync
parameter to external and no signal is active on the “Sync In”, the program displays a
warning message. The polarity of the “Sync In” signal may be inverted.
Sync Out
The sync out mode can be configured:
•
Default: the sync out signal follows the sync in (internal or external). The signal width
is the exposure time.
•
Inverted Default: the signal follows the sync in as in the default, but it’s inverted.
•
Configurable Width: the user can define the width of the sync out signal.
•
Inverted Configurable Width: like in the option above, but inverted.
•
Disabled: the sync out signal is disabled.
A “Delay” can also be added to the Sync Out signal.
Alignment: when the auto-exposure option is selected the exposure is done at the end of
the acquisition period. Then the period and exposure are not aligned. The alignment
option is used to decide whether the sync out will be aligned to the period or to the
exposure.
Marker
If this option is enabled, the user can send to the camera a pulse that gets recorded in
one frame. The recorded pulse is a marker in the frame and lets the user know that
something happened at that time. The marker is shown in the frame if the “Marker” Time
stamp option is selected.
The pulse can be sent through the “Sync In” connector or the “Trigger In” connector.

Test Session Name
This parameter is the name of the Test session folder and it is created before saving the
images. It will contain all the acquisition folders.
Assign the same name to the acquisition
If this option is selected, the acquisition folder name is the same of the session folder. If
more than one acquisition is saved, a number is added to the folder name in order to
avoid overwriting the images.
Acquisition Folder name
This parameter is the name of the prefix of the acquisition folder. Each folder name is
created by adding a number to this parameter (for example, if the name is “Acq” the
folders will be “Acq_000”, “Acq_001”…).
Overwrite folder
If this option is unchecked, the software creates a different folder each time the images
are saved (Acq_000, Acq_001 …).
If the parameter is checked, two options are available:
• The “Download images after acquisition and restart” option is not selected. In this
case the program saves the images in the same folder all the time. Example: the
folder name is A. then the program creates the folder A the first time and saves the
images. If subsequent acquisitions are done, the program saves the images in the
same A folder and overwrites them.
• The “Download images after acquisition and restart” option is selected. In this case
the program creates folder names from the acquisition name with 7 digits. Example:
the acquisition name is A, then the program creates A_0000000, then A_0000001,
then A_0000002 and so on.

Camera Calibration
To reduce the noise associated with CMOS sensors and improve the performance of the
default calibration file, Motion Studio offers a Calibration dialog box.
1. Select Camera from the main toolbar.
2. Select Advanced > Camera Calibration.
To reduce the noise associated to the CMOS sensor and improve the performance of the
default calibration file, select the following options:
•
Enable background removal (factory calibration): it removes the background
from any acquired images and reduces the noise.
•
Enable pixel sensitivity correction (factory calibration): it enables the
compensation of differences in pixels sensitivity.
•
Enable noise reduction with dark columns: the option enables or disables the
use of masked (dark) columns to reduce the time-dependent noise. In some
camera models the option is enabled and cannot be disabled.
•
Acquire the background images in the optimal conditions: the camera lens
cap must be on. The driver acquires the background images in the optimal
conditions for all the parameters (exposure, rate, sensor gain and pixel gain). The
background images are not saved into the calibration file. This option is disabled
on “new design” cameras.
•
Reload factory calibration file: the driver loads the default camera calibration
file. This option is useful if the user wants to reload the default background
images
To reduce the background noise in current conditions, select the following options.
98
•
Enable current condition background removal: if this option is selected the
driver uses the background images that have been acquired in current conditions
and corrects the images. The background calibration data is saved in a file and
reloaded when the program is launched. This option is disabled on “new design”
cameras.
•
Enable current condition pixel sensitivity correction: if this option is selected
the driver uses the coefficients that have been computed in current conditions
and corrects the acquisitions. The coefficients are saved in a file and reloaded
when the program is launched. This option is disabled on “new design” cameras.
•
Acquire the background images in current conditions: the camera lens cap
must be on. The driver computes the background images for the current
operating conditions. If the sensor gain or the region of interest change after the
calibration, the correction may be wrong. This option is disabled on “new design”
cameras.
•
Acquire the PSC images in current conditions: the lens must be removed and
a constant light should illuminate the sensor. The driver computes the pixel
sensitivity correction coefficients for the current operating conditions. If sensor
gain and region of interest change after the calibration, the correction may be
wrong. This option is disabled on “new design” cameras.
•
Reset current conditions file: if this option is selected, the current conditions
calibration file is deleted and the current images and coefficients are reset.

Image parameters
Some advanced parameters may be changed.
TNK (Temporal Noise Killer): the slider controls the time-dependent noise reduction
filter. Each pixel value is compared with the same pixel value in images acquired before
and after and the result is used to eliminate the component of noise that is not a fixed
pattern.
Anti-Alias (Gaussian): the slider controls the strength of the smoothing effect on the
image. The effect is a reduction of image noise and a reduction of details due to the
blurring.
Sharpen Threshold. The parameter is used in the sharpening algorithm and controls the
minimum brightness change that is sharpened.
DNR (Dynamic Noise Reduction): reduce the effect of noise in the image (not all the
camera modesl suppor tit).
JPEG compression: some camera models support JPEG compression. Move the slider
to the right side to increase the compression ratio and reduce the image quality.
IDT recommends that those parameters are not changed. The values should be
always set to default (optimized image quality).

Master/Slave operation modes
In this operation mode, one of the cameras acts as the master and the others as slaves.
The master camera controls itself and some of the configuration parameters of the slaves,
such as record mode, acquisition rate, etc. To set one camera as master, check the
“Master Camera” check box on the “Camera Control” group in the camera control bar.
The check box is hidden when only one camera is connected.
The master camera drives the slaves’ acquisitions via the sync out signal. The picture
below shows how to configure a two cameras master/slave layout.
Slave Camera
Master Camera
Trigger
Master camera’s “Sync Out” signal must be connected to slave camera’s “Sync In”
connector. To provide simultaneous trigger to cameras (circular and BROC mode),
master camera and slave camera should receive the same trigger signal.
Two Master synchronization modes are available:
1. Sync Master/Slave: the master camera produces a synchronization signal whose
frequency is the same as the master cameras frame rate. The slave cameras are
automatically configured to operate with external frame sync and all the cameras
run at the same frame rate.
2. 1PPS Master/Slave: The master camera generates “1PPS” sync out signal (1 Hz)
and operates with the internal sync clock. The slave cameras are automatically
108
Users Manual

configured to operate with external 1PPS sync and they align their internal sync
signal to the external 1PPS reference. In this fashion, the slave cameras may
operate at any frequency that is a multiple of the master’s operating frequency.
The master sync signal is similar to a GPS reference signal that is used to align the
acquisition frame rates.
This mode is not supported by all the camera models.

Set Image intensity: when a new track-point is added the program computes the
intensity range on the current image. The current image will be considered as a reference
image for the computations. If the option is disabled, no intensity is computed.
Filter image: before each computation a set of sharpening filters is applied to the images.
The filters reduce the effect of the background on the computation. If the option is
disabled no filter is applied before the computations.
Validate position: after the regular calculation of a track point a least squares algorithm
is applied. The algorithm is performed with the point and other four points (two before and
two after). The result is used to correct (validate) the point position.
Mode: the tracking algorithm can be adapted to different tracking conditions (deformable
translation, rigid translation and rigid translation with rotation).
Displacement range: the displacement from one point to the next may have a limited
range. Enter the values to avoid errors.

Simplified calibration model
This method requires that the calibration target is vertically aligned with the camera, i.e.
vertical lines in the target correspond to vertical lines on the target image. The rectangular
grid has four handles that may be dragged over four reference points of the calibration
image.
To achieve more precision the zoom factor may be set to 300 or 400 and the handles
may be positioned upon the calibration target marks.
With the simplified calibration two options are available:
1. The camera plane is parallel to the target plane and there is no perspective: the
calibration is just a way to find a constant value that will be multiplied by the pixel
displacements to find the space displacements. Both horizontal and vertical lines of
the calibration target are perfectly parallel to the rectangle sides. In the Calibration
dialog box, the “Use Perspective” option is OFF, and the rectangle sides are parallel.
2. The camera plane is not parallel to the target plane and there is a perspective effect.
The effect is computed only on horizontal lines while vertical line must be parallel to
the rectangle vertical sides. In the Calibration dialog box, the “Use Perspective” option
is ON.
X/Y Dimensions: the user enters the dimensions in mm of the rectangle. The distance
between the points of the calibration target is known. The values are in mm.
Focal Length: the camera focal length in mm.
Diagonal: when the “Use perspective” option is off, the user may check the “Use
diagonal” check box and enter the rectangle diagonal length instead of Width and height.
Grid Color: the color of the calibration grid may be changed.
Pixel size: the user may edit the pixel size. Click “Find size…” to select the camera model
and find the correct size.

Generic calibration model
The generic calibration considers different kind of distortion due to optical and/or
perspective issues. The calibration grid is more complex than a rectangle, is a multi-point
grid (see below). The points of the grid will be positioned over the marks of the calibration
target. Then the program computes the parameters of a third grade polynomial which
maps the points of the image (pixels) into the points of the real space (mm).
The grid may be moved and resized. The way the grid is resized is controlled by the “Grid
Mode” in the calibration dialog:
•
Zoom: in this mode the handles are positioned over the four external corners of the
grid. The grid may be zoomed or moved.
•
Constrained: in this mode the handles are positioned over the four external corners
of the grid. The grid can be distorted.
•
Free: in this mode each point of the grid has its own handle and can be moved
independently.
Grid Size (X/Y): the user enters the dimensions in mm of the grid (distance between the
grid corners). The distance between the points of the calibration target is known. The
values are in mm (1 inch = 25.4 mm).
Grid Nodes (X/Y): the user enters the number of nodes in the grid. The minimum is 4,
while the maximum is 20. The number of nodes depends on the calibration target.

5.39.8.3. Internal Mode
Output waveforms are generated by the internal clock. The user may adjust the internal
frequency or period and the duty cycle. The channel may be inverted and gated by
another signal. The gate can be selected among the external inputs (0 or 1) or among
one of the other output channels.
The diagram below shows an example with the following configuration:
ƒ
Output channel 0: F = 100 Hz, duty cycle 50%, no gate.
ƒ
Output channel 1: F = 50 Hz, duty cycle 50%, no gate.
ƒ
Output channel 2: F = 100 Hz, duty cycle 50%, gate = output channel 0.
The output channel 0 frequency is 100 Hz. The output channel 1 frequency is 50 Hz. The
output channel 2 frequency is 100 Hz but the channel is gated by the output 0, so the
result is a signal which has 100 Hz frequency and a duty cycle of 25%.
Output Channel 0 (100 Hz – DC = 50%)
Output Channel 1 (50 Hz – DC = 50%)
Output Channel 2 (100 Hz – gate=chn 0)

Users Manual
Motion Studio
5.39.8.4. External Mode
Output waveforms are generated by an external signal. The user may adjust the output
channel divider and duty cycle. The output channel may be inverted and gated by another
signal. The gate can be selected among the external inputs (0 or 1) or among one of the
other output channels.
Let’s assume that the external frequency is 200 Hz. The diagram below shows an
example with the following configuration:
ƒ
Output channel 0: F = 100 Hz, duty cycle 50%, external input 0, no gate.
ƒ
Output channel 1: F = 50 Hz, duty cycle 50%, external input 0, no gate.
ƒ
Output channel 2: F = 100 Hz, duty cycle 50%, external input 0, gate = output
channel 0.
The output channel 0 frequency is half the external frequency. The output channel 1
frequency is one fourth the external frequency. The output channel 2 frequency is equal
to the external frequency but the channel is gated by the output 0, so the result is a signal
which has half the external frequency and a duty cycle of 25%.
External Input 0 clock signal (200 Hz)
Output Channel 0 (100 Hz – DC = 50%)
Output Channel 1 (50 Hz – DC = 50%)

5.39.8.5. Start/Stop Mode
The two external signals drive the output signals generation. The input 0 starts the output,
while input 1 stops it. The frequency and delay of the output are configured as in “internal”
mode. No gate is allowed. When the stop signal level is high, the output signal is
truncated.
The diagram below shows an example with the following configuration:

Frequency 2 value.
The diagram below shows an example with the following configuration:
ƒ
Output channel 0: mode = Rate Switch, F1 = 100 Hz, duty cycle1 = 50%, F2 = 50
Hz, duty cycle1 = 50%. When the input 0 level goes high, the output signal starts at
100 Hz. When the input 1 level goes high, the output 0 frequency switches to 50 Hz.

5.39.8.7. “Burst Single” Mode
In burst (single) mode, one of the external inputs or one of the output channels is used as
trigger to generate one or more pulses. The frequency and the Duty cycle controls are
used to determine the duration of the pulse. The generation of the pulses may be also
delayed. Both the output signal and the trigger may be also inverted.
The diagram below shows an example with the following configuration:
ƒ
Output channel 0: mode = Burst (single), Trigger = External Input 0, F = 100 Hz,
duty cycle = 50%, pulses = 3. The external Input 0 serves as a trigger. When the
trigger goes high, three pulses are generated by the output channel 0. The duration of
the pulses is about 5 ms (50 % of 100 Hz). The pulses are generated once.

5.39.8.8. “Burst retriggered” mode
The Burst retriggered mode is equivalent to the burst single mode. The pulses are

Output channel 0: mode = Burst (retriggered), Trigger = External Input 0, F = 100 Hz,
duty cycle = 50%, pulses = 2. The external Input 0 serves as a trigger. When the trigger
goes high, three pulses are generated by the output channel 0. The duration of the pulses
is about 5 ms (50 % of 100 Hz). The pulses are generated each time the trigger goes
high.

The Timing Hub may be used to synchronize a camera or other devices. The Signal
Generation options are:
•
User: the output signal synchronizes an external device. No internal control is done
by the program.
•
Camera (simple): the label edit box will be converted into a list of open cameras. In
the camera dialog bar the “Rate” control will be disabled, the “Rate Sync” control will
be set to “External” and the camera operation frequency will be configured directly
from the timing panel. If the “Sync Cfg” value is set to “Pulse High” or to “Pulse Low”,
the camera exposure is controlled by the duty cycle of the external square wave. In
this condition the exposure edit box is grayed out and the value is automatically
computed.
1. If the “Sync Cfg” value is set to Pulse High, the exposure is equal to the inverse of
the output channel frequency multiplied by the duty cycle.
2. If the “Sync Cfg” value is set to Pulse Low, the exposure is equal to the inverse of
the output channel frequency multiplied by (100 - duty cycle).

7. Frame Synchronization and Event Triggering
7.1. Overview
The camera and software enable external sync and triggering capabilities. The camera is
synchronized externally via a trigger source in the form of a TTL pulse. The
synchronization INPUT signals as well as a synchronization OUTPUT signal are handled
through BNC connectors. The synchronization signal is output for every frame that is
acquired and can supply the time reference for other pieces of hardware, for example a
strobe for illumination.
Two options are available:
1. Cameras with 2 BNC connectors: 1 input connector is used for synchronization and
event triggering. The output connector is used for sync out.
2. Cameras with 3 BNC connectors: a “Trig In” connector is used for event triggering,
a “Sync in” connector is used for external synchronization. The output connector is
used for sync out.

7.4. Triggering the camera and synchronizing with strobe light
The camera cab is used together with a strobe for illumination. In this case it is necessary
to synchronize the illumination pulse event with the camera exposure. Examples of
methods that can be employed are presented in the following. The schematics of various
timing diagrams are included. This diagram assumes the use of an externally pulse(s)
(TTL) to synchronize both the camera and the strobe.
7.4.1. Synchronizing via the leading edge of a pulse event (Single
exposure)
The figure shows the timing signals in a single exposure configuration. In the Record Tab
the frame sync is set to “External Edge-High” and the exposure mode is set to “single”.
The camera exposure is started by the leading edge of the pulse signal and the exposure
duration is set in the “Exposure” control of the camera software panel.
Definitions:
•
Input sync pulse is TTL level.
•
Illumination pulse duration: typical 7-10 ns for flash lamp and 100-150 ns for diode
pumped lasers respectively).
•
Camera exposure > Illumination latency + Illumination pulse duration.

7.4.4. Synchronizing in double exposure mode
The figure below shows the timing signal in a typical double exposure PIV configuration.
In the camera panel the sync mode is set to “External Edge-High” and the exposure mode
is set to “double”. The time between the two laser pulses must be larger than the sum of
the first laser pulse duration and the camera frame transfer time. The second exposure
duration cannot be set and depends from the camera frame readout, so the second laser
pulse duration must be configured to the desired exposure time.

9.1. Formats Overview
9.1.1. TIFF Format
TIFF pictures store a single raster image at any color depth. TIFF is arguably the most
widely supported graphic file format in the printing industry. It supports optional
compression, and is not suitable for viewing in Web browsers.
The TIFF format is an extensible format, which means that a programmer can modify the
original specification to add functionality or meet specific needs. This can lead to
incompatibilities between different types of TIFF pictures.
9.1.2. Bitmap Format
Windows bitmap files are stored in a device-independent bitmap (DIB) format that allows
Windows to display the bitmap on any type of display device. The term "device
independent" means that the bitmap specifies pixel color in a form independent of the
method used by a display to represent color. The default filename extension of a
Windows DIB file is .BMP.
For further information, refer to the Microsoft™ documentation.

Motion Studio
9.1.3. JPEG Format
The name "JPEG" stands for Joint Photographic Experts Group, the name of the
committee that created the standard. The JPEG standard specifies both the codec, which
defines how an image is compressed into a stream of bytes and decompressed back into
an image, and the file format used to contain that stream. The compression method is
usually lossy, meaning that some visual quality is lost in the process and cannot be
restored. However there are variations on the standard baseline JPEG that are lossless.
9.1.4. PNG Format
PNG is an extensible file format for the lossless, portable, well-compressed storage of
raster images. PNG provides a patent-free replacement for GIF and can also replace
many common uses of TIFF. Indexed-color, grayscale, and true-color images are
supported, plus an optional alpha channel. Sample depths range from 1 to 16 bits.
PNG is designed to work well in online viewing applications, such as the World Wide
Web, so it is fully stream-able with a progressive display option. PNG is robust, providing
both full file integrity checking and simple detection of common transmission errors. Also,
PNG can store gamma and chromaticity data for improved color matching on
heterogeneous platforms.
PNG is a platform-independent format that supports a high level of lossless compression,
alpha channel transparency, gamma correction, and interlacing. It is supported by more
recent Web browsers.
9.1.5. TP2 format
Type-2 format is the Redlake raw data format. It’s the format used to save raw image
data.
9.1.6. FBA format
The FBA format is the Falcon eXtra raw data format. It’s the format used by Falcon eXtra
software to save raw image data. For further information, please refer to falcon
documentation.
9.1.7. AVI Format
The Microsoft AVI file format is a Resource Interchange File Format (RIFF) file
specification used with applications that capture, edit, and play back audio-video
sequences. In general, AVI files contain multiple streams of different types of data. Most
AVI sequences use both audio and video streams. A simple variation for an AVI
sequence uses video data and does not require an audio stream. The program supports
uncompressed (raw) and compressed AVI. The INDEO 5.11 codec is installed on 32-bit
Windows.
9.1.8. MOV Format
The Apple Quick Time MOV file format is used with applications that capture, edit, and
play back audio-video sequences. In general, MOV files contain multiple streams of
different types of data. The codec supported in Motion Studio are RAW, TIF and H264.
Apple QuickTime™ is required.

9.1.9. BLD Format
The BLD format corresponds to the file format RAW, which is known from several
applications. Each BLD file needs a corresponding descriptor file in the DSC format. In a
BLD file all single frames of an image sequence are stored successively uncompressed in
the block format. The data is in binary raw data format (e.g. for grayscale pictures 1 Byte
per Pixel). The descriptor file (DSC) belonging to the BLD file is a line-orientated ASCII
file, in which values like e.g. resolution, frames or date are stored. The DSC file can be
created with any text editor.
9.1.10.
MPEG Format
MPEG, which stands for “Moving Picture Experts Group”, is a name of family standards
used for coding audio-visual in a digital compressed format. MPEG is a generic means of
compactly representing digital video and audio signals for consumer distribution. The
basic idea is to transform a stream of discrete samples into a bit-stream of tokens which
takes less space, but is just as filling to the eye. The graphic library implements the
MPEG-1 format, the standard on which such products as video CD and MP3 are based.
The compression/decompression technique implemented in MPEG is “lossy”, e.g. some
amount of data information is lost.
9.1.11.
MPEG H.264 (Advanced Video Coding)
It is also known as MPEG-4 Part 10 or MPEG-4 AVC (Advanced Video Coding). The
intent of the H.264 project was to create a standard capable of providing good video
quality at substantially lower bit rates than previous standards without increasing the
complexity of design so much that it would be impractical or excessively expensive to
implement. An additional goal was to provide enough flexibility to allow the standard to be
applied to a wide variety of applications on a wide variety of networks and systems,
including low and high bit rates, low and high resolution video and broadcast. The MPEG
H.264 format is supported only on a 32 bit Windows OS with installed QuickTime™.
9.1.12.
Multi-page Bayer Format (MRF)
Multi-page Bayer Format (MRF) is an uncompressed IDT proprietary file format. Multiple
raster images are stored in a single file. The format is described below.
Each MRF file contains a file header, an image header and an array of bytes that defines
the image data bits. The image raster data is not compressed and stored in the file “as it
is”. Mono images pixel depth may be 8, 9 or 10; color images are stored in Bayer format
(8, 9, 10 bit) or in BGR format (24, 27, 30 bit). The file structures are the following:
9.1.12.1. File header
A MRF file begins with a file header structure containing the IDT signature.
typedef struct _MRFFILE_HEADER
{
char szSign[8];
// IDT signature
unsigned int nReserved;
// reserved
} MRFFILE_HEADER, *PMRFFILE_HEADER;

szSign[8]: a 8 char buffer which contains the signature “IDT-MRF”. It indicates that the
file contains a valid Multiple Raw File.
nReserved: this field is reserved for future use.
9.1.12.2. Image header
The file header is followed by the image header which contains general information about
the images.
typedef struct _MRFIMG_HEADER
{
unsigned int nSize;
unsigned int nPages;
unsigned int nWidth;
unsigned int nHeight;
unsigned int nBPP;

11. Appendix C - Spatial filtering
Spatial filters alter pixel values with respect to variations in light intensity in their
neighborhood. The neighborhood of a pixel is defined by the size of a matrix, or mask,
centered in the pixel itself. These filters can be sensitive to the presence or the absence
of light intensity variations. Spatial filters can serve a variety of purposes, such as
detecting edges along a specific direction, contouring patterns, reducing noise and detail
outlining and smoothing.
Spatial filters fall in two categories:
High-pass filters emphasize significant variations of the light intensity usually found at
the boundary of object. They are also called sharpening filters.
Low-pass filters attenuate variations of the light intensity. They have the tendency to
smooth images by eliminating details and blurring edges. They are also called
smoothing filters.
In the case of a 3x3 matrix, the value of the central pixel derives from the values of its
eight surrounding neighbors. A 5x5 matrix specifies 24 neighbors; a 7x7 matrix specifies
48 neighbors and so forth.
If P(i,j) specifies the intensity of the pixel P with the coordinates (i,j), the pixels surrounding
P(i,j) can be indexed as follows (in the case of a 3x3 matrix):
P(i-1,j-1)
P(i,j-1)
P(i+1,j-1)
P(i-1,j)
P(i,j)
P(i+1,j)
P(i-1,j+1)
P(i,j+1)
P(i+1,j+1)
A linear filter assigns to P(i,j) a value which is a linear combination of its surrounding
values. For example:
P(i,j) = P(i-1,j-1) + P(i,j-1) + P(i+1, j-1) - P(i-1,j+1) - P(i,j+1) - P(i+1,j+1)
A nonlinear filter assigns to P(i,j) a value that is not a linear combination of the
surrounding values. For example:
P(i,j) = max( P(i-1,j-1), P(i+1, j-1), P(i-1,j+1), P(i+1,j+1) )
11.1. Linear filters (Convolution filters)
A convolution is a mathematical function that replaces each pixel by a weighted sum of its
neighbors. The matrix defining the neighborhood of the pixel also specifies the weight
assigned to each neighbor. This matrix is called the convolution kernel.
For each pixel P(i,j) in an image, the convolution kernel is centered on P(i,j). Each pixel
masked by the kernel is multiplied by the coefficient placed on top of it. P(i,j) becomes the
sum of these products.
200
Users Manual
Motion Studio
In the case of 3x3 neighborhood, the coefficients of the kernel matrix can be indexed as
follows.
K(i-1,j-1)
K(i,j-1)
K(i+1,j-1)
K(i-1,j)
K(i,j)
K(i+1,j)
K(i-1,j+1)
K(i,j+1)
K(i+1,j+1)
The grater the absolute value of a coefficient K(a,b), the more the pixel P(a,b) contributes to
the new value of P(i,j). If a coefficient K(a,b) is 0, the neighbor P(a,b) does not contribute to
the new value of P(i,j).

If the kernel contains both negative and positive coefficients, the transfer function is
equivalent to a weighted differentiation and produces a sharpening or high-pass filter (like
Laplacian, Prewitt and Sobel filters).
If all coefficients in the kernel are positive, the transfer function is equivalent to a weighted
summation and produces a smoothing o low-pass filer (like Average and Gaussian
filters).
11.2. Linear sharpening filters
Typical smoothing filters are:
Gradient filters
A gradient filter highlights the variation of light intensity along a specific direction, which
has the effect of outlining edges and revealing texture.
A gradient convolution filter is a first-order derivative. Its kernel uses the following matrix:
a
-b
c
b
x
-d
c
d
-a
Where a, b, c and d are integer coefficients and x=0 or x=1.
This kernel has an axis of symmetry that runs between the positive and negative
coefficients of the kernel and through the central element. This axis of symmetry gives the
orientation of the edges to outline.

There are two sets of pre-defined gradient filters used in Motion Studio. They are listed
below.
The Prewitt filters have the following kernels. The notations N (north) NE(north-east) E
(east) SE (south-east) S (south) SW (south-west) W (west) NW (north-west) indicate
which edges of bright regions they outline.
The Sobel filters are very similar to the Prewitt filters except that they highlight light
intensity variations along a particular axis that is assigned a stronger weight. They have
the following kernels.
Laplacian filters
A Laplacian filter highlights the variation of the light intensity surrounding a pixel. The filter
extracts the contour of objects and outline details. Unlike the gradient filter, it is omni
directional.
The Laplacian filter is a second-order derivative. Its kernel uses the following matrix:
a
d
c
b
x
b
c
d
A
where a, b, c and d are integers.
The Laplacian filter has two different effects, depending on whether the central coefficient
x is equal or greater than the sum of the absolute values of the outer coefficients.
If x is equal to that sum, the filter extracts the pixels where significant variations of light
intensity are found. The presence of sharp edges, boundaries between objects,
modification in the texture of a background, noise, and other effects can cause these
variations. The transformed image contains white contours on a black background.
If x is greater than that sum, the filter detects the same variations as mentioned above,
but superimposes them over the source image. The transformed image looks like the
source image, with all significant variations of the light intensity highlighted.
11.3. Linear Smoothing filters
A smoothing filter attenuates the variations of light intensity in the neighborhood of a
pixel. It smoothes the overall shape of objects, blurs edges, and removes details.
It is an averaging filters and its kernel uses the following matrix:
a
202
d
c
Users Manual
Motion Studio
b
x
b
c
d
a
where a, b, c and d are positive integers, and x=0 or x=1.
Because all the coefficients are positive, each central pixel becomes a weighted average
of its neighbors. The stronger the weight of a neighbor is. The more influence it has on
the new value of the central pixel.
A list of average smoothing kernels is shown below
A Gaussian filter attenuates the variations of light intensity in the neighborhood of a
pixel. It smoothes the overall shape of objects and attenuates details. It is similar to a
smoothing filter, but its blurring effect is more subdued.
Its kernel uses the following matrix.
a
d
c
b
x
b
c
d
a
where a, b, c and d are positive integers, and x=0 or x=1.
Because all the coefficients are positive, each central pixel becomes a weighted average
of its neighbors. The stronger the weight of a neighbor is. The more influence it has on
the new value of the central pixel.
Unlike a smoothing kernel, the central coefficient of a Gaussian filter is greater than 1.
Therefore the original value of a pixel is multiplied by a value greater than the weight of
any of its neighbors. As a result, a greater central coefficient corresponds to a more
subtle smoothing effect. A larger kernel size corresponds to a stronger smoothing effect.

11.4. Nonlinear filters
A nonlinear filter replaces each pixel with a nonlinear function of its surrounding pixels.
Like the convolution filters the nonlinear filters operate on a neighborhood.
A Median filter is a nonlinear low pass filter that assigns to each pixel the median value
of its neighborhood, effectively reducing isolated pixels and reducing details. However,
the median filter does not blur the contour of objects.
A Maximum Filter is a nonlinear filter that assigns to each pixel the maximum value of
pixels in its neighborhood. This has the effect to increase the contrast of the image.
A Dilation of an image is a particular case of max filter. The output pixel is set to the
maximum of the corresponding input pixel and its 8 neighbors. The effect of dilation is to
fill up holes and to thicken boundaries of objects on a dark background (that is, objects
whose pixel values are greater than those of the background).
A Minimum Filter is a nonlinear filter that assigns to each pixel the minimum value of
pixels in its neighborhood. This has the effect to decrease the contrast of the image.
An Erosion of an image is a particular case of min filter. The output pixel is set to the
minimum of the corresponding input pixel and its 8 neighbors. The effect of erosion is to
remove spurious pixels (such as noise) and to thin boundaries of objects on a dark
background (that is, objects whose pixel values are greater than those of the
background).
Opening an image is a sequence of erosions followed by dilations. The process of
opening has the effect of eliminating small and thin objects, breaking objects at thin
points, and generally smoothing the boundaries of larger objects without significantly
changing their area.
Closing an image is a sequence of dilations followed by erosions. The process of closing
has the effect of filling small and thin holes in objects, connecting nearby objects, and
generally smoothing the boundaries of objects without significantly changing their area.

12. Appendix D - Color Filter Arrays (CFA)
The Color camera uses a single image sensor. Color imaging with a single sensor
requires the use of a Color Filter Array (CFA) which covers the sensor array. In this
fashion each pixel in the detector samples the intensity of just one of the three color
components, i.e. red, green or blue. The recovery of full-color images from a CFA-based
sensor requires a method of calculating values of the other color separations at each
pixel. These methods are commonly referred as color interpolation or color “demosaicing”
algorithms.
In a single-sensor camera, varying intensities of light are measured at a rectangular grid
of image sensors. To construct a color image, a CFA must be placed between the lens
and the sensors. A CFA typically has one color filter element for each sensor. Obviously,
the color interpolation algorithms depend on the CFA configuration. Many different CFA
configurations have been proposed. The one used in IDT cameras is the Bayer pattern.
A Bayer pattern consists of pixels on your sensor tinted green, red or blue and set in a
mosaic pattern. Consider the figure below: moving from left to right and then down, you
see that you have a GR-BG pattern. This is your Bayer pattern, and is then placed all
over the sensor to form the Bayer Mosaic Pattern. This means that you have half of your
pixels tinted with a Green sensitive element, a quarter tinted with a Red sensitive
element, and a quarter tinted with a Blue sensitive element.
The MotionPro/MotionScope camera models have different Bayer patterns:
•
X3, Y3-C, Y3-HD, N3-S1, N3-S2 and M3 have BG-GR pattern.
•
X4, X5, Y5, Y5 HD, M5, and N5 have GR-BG pattern.
•
Y4, N4, Y3-S1, Y3-S2, N3-S3, N3-S4, Y6, Y7, NX7, Y8, NX8 have GB-RG pattern.
The camera driver may perform six different interpolation algorithms (demosaicing):
ƒ
Advanced: a new advanced method for high quality reconstruction.
ƒ
Nearest: the algorithm is based on nearest neighbor reconstruction.
Users Manual
205
Motion Studio
ƒ
Bilinear: for each missing pixel, a weighted value of the surrounding four pixels is
computed. It’s the simplest method and is non-adaptive. The indiscriminate averaging
of neighboring pixel causes a blur effect (“Zipper”).
ƒ
Gradient A: the interpolation is done using chrominance gradients in two steps. First
the luminance channel is interpolated (green). Then the color differences (red minus
green and blue minus green) are interpolated.
ƒ
Gradient B: the interpolation is done using luminance gradients in a more adaptive
way than algorithm B.
ƒ
Gradient C: the interpolation is done using a threshold based variable number of
gradients.
ƒ
Hue Transition A: the algorithm is based on the assumption that the hue of the
image cannot change abruptly and in an unnatural manner. The term hue refers to
the relation between luminance (green) and chrominance (red, blue).
ƒ
Hue Transition B: based on the same principles of “A” method, but more precise
ƒ
Pixel Grouping: the algorithm is based on the observation that natural scene images
are usually composed of numerous groups of pixels, and have approximately the
same brightness and color.

13. Appendix E – EDR/XDR
The Extended Dynamic Range (EDR/XDR) is an IDT-proprietary implementation that
enhances the camera dynamic range. Cameras with 8 bit pixel depth (X-series) may
increase the dynamic range to 11 bits. Cameras with 10 bit dynamic range (Y-series and
N-series) may increase the dynamic range to 13 bit.
Let’s imagine a picture of a high contrast scene. In the picture we may have a very bright
portion (almost saturated) and a very dark portion that is almost black.
How can we change our exposure to have a good image? If we try to increase the
exposure to improve the dark details, we saturate the bright area. On the other side, if we
decrease to improve the bright area, we reduce the light to the dark area and we loose
information.
The solution is EDR/XDR.
EDR is implemented in Y4/N4 cameras. The sensor is capable of acquiring even and odd
rows with different exposures. The two “half images” are then interpolated to produce two
different images with two different intensities.
XDR is implemented in all the camera models that support double exposure.
Then the pictures are linearly combined to obtain a third picture with increased sensitivity.
The ratio between higher exposure and lower exposure gives the new pixel depth, which
can be 9, 10 or 11 bits for 8 bit images or 11, 12 and 13 bits for 10 bit images.
The resulting image may be converted back to 8 bits (or 10 bits) with a look up table.
The example below shows the result of EDR/XDR. The first image shows a dark area at
the top left side.
If we increase the exposure, the top left side becomes visible but the image saturates at
the right side (see below).

With XDR the two images are combined and the result is a uniform image without dark or
saturated zones.

Ambient Light
It’s the available natural light completely surrounding a subject. It’s tight already existing

light source.
Aperture
It’s the lens opening. The hole or opening formed by the metal leaf diaphragm inside the
lens or the opening in a camera lens through which light passes to expose the sensor.
The size of aperture is either fixed or adjustable. Aperture size is usually calibrated in fnumbers-the larger the number, the smaller the lens opening. Aperture affects depth of
field, the smaller the aperture, the greater is the zone of sharpness, the bigger the
aperture, the zone of sharpness is reduced. The size of the aperture is indicated by its fnumber.

Bandwidth
It’s the capacity of a networked connection and determines how much data can be sent
along the networked wires. The bandwidth is particularly important for Internet
connections, since greater bandwidth also means faster downloads.
Bayer pattern
A Bayer pattern consists of pixels on the sensor tinted green, red or blue and set in a
mosaic pattern. Moving from left to right and then down, the pattern may be GR-BG. This
is the sensor’s Bayer pattern, and is then placed all over the sensor to form the Bayer
Mosaic Pattern. This means that half of the pixels are tinted with a Green sensitive
element, a quarter tinted with a Red sensitive element, and a quarter tinted with a Blue
sensitive element.
Binning
Binning is a method of increasing camera speed and sensitivity to boost low signals.
Binning causes the acquired image to be brighter and smaller, but the resolution will be
lower as a result. Because the image is smaller, the image transfer time is reduced
significantly. When you select a binning setting in your imaging software, the camera
combines data from several pixels in the camera’s CCD into a single super pixel. For
example, a 2x2 bin means that 2 pixels in the horizontal direction and 2 pixels in the
vertical direction are combined to form one super pixel.
Bit Depth
It’s the color or gray scale of an individual pixel. A pixel with 8 bits per color gives a 24 bit
image. (8 Bits x 3 colors are 24 bits.) 24 bit color resolution is 16.7 million colors.
BMP (Bitmap)
It’s a file format used to store images. For further information, refer to the Microsoft™
documentation.
BNC
BNC is the acronym for Bayonet Neill-Concelman (for the inventors Paul Neill and Carl
Concelman). It’s a twist-and-lock connector for coaxial cables, used for electronic
equipment and for wiring LANs.
Brightness

to white. It’s usually defined as brightness levels ranging in value from 0 (black) to 255
(white).

CCD (Charge Coupled Device)
It’s the light sensitive silicon chip near the optical interface of the camera that converts
light intensities into electrical signals. Every pixel's charge is transferred through a very
limited number of output nodes (often just one) to be converted to voltage, buffered, and
sent off-chip as an analog signal. All of the pixel can be devoted to light capture, and the
output's uniformity (a key factor in image quality) is high.
Circular Mode
It’s one of the operating modes of a camera with on board memory. The camera acquires
and restarts when the memory is filled. The camera waits for an event trigger to complete
the acquisition.
CFA (Color Filter Array)
The filter dyes placed directly over each pixel on the chip surface.
CMOS (Complementary Metal-Oxide Semiconductor)
It’s the light sensitive silicon chip near the optical interface of the camera that converts
light intensities into electrical signals. Each pixel has its own charge-to-voltage
conversion, and the sensor often also includes amplifiers, noise-correction, and
digitization circuits, so that the chip outputs digital bits. These other functions increase the
design complexity and reduce the area available for light capture. With each pixel doing
its own conversion, uniformity is lower. But the chip can be built to require less off-chip
circuitry for basic operation.
Contrast
It’s a measure of rate of change of brightness in an image.

when needed by a larger program that is running in the computer. The small program that
lets the larger program communicate with a specific device such as a printer or scanner is
often packaged as a DLL program (usually referred to as a DLL file). The advantage of
DLL files is that, because they don't get loaded into RAM together with the main program,
space is saved in RAM.
Dynamic Range
It’s the ratio of the saturation level of the CCD to the readout noise of the CCD camera
system. Dynamic range is a measure of the ability of the camera to capture both bright
and dark features in a single image. In general, the higher the camera’s dynamic range,
the more information per pixel it can capture. It’s usually expressed in dB.

USB (Universal Serial Bus)
It’s a serial bus standard for connecting devices. It was designed for computers such as
PCs and the Apple Macintosh, but its popularity has prompted it to also become
commonplace on video game consoles, PDA, cell phones. It has a slow version (USB 1.1
– 12 Mbps) and a high speed version (USB 2.0 – 480 Mbps).
USB 2.0
Finalized in 2001, Universal Serial Bus (USB) 2.0 is a complete overhaul of the Universal
Serial Bus input/output bus protocol which allows much higher speeds than the older USB
1.1 standard did. The goal of the new serial bus is to broaden the range of external
peripherals that can be used on a computer. A hard drive can easily hit the USB 1.1
bottleneck whereas it now becomes more 'usable' under USB 2.0 conditions. USB 2.0
maximum speed is 480 Mbps.
