BM-141GE / BB-141GE
1. General
This manual covers the digital monochrome progressive scan camera BM-141GE and color progressive scan camera BB-141GE
BM-141GE/BB-141GE is a GigE Vision compliant camera, belonging to the C3 Basic family. Both the monochrome version BM-141GE and the color version BB-141GE provide a frame rate of 30 frames/second at full resolution. Using vertical binning (BM-141GE only), draft mode (BB-
141GE only) or partial scan, the camera can achieve faster frame rates.
The 2/3" CCD with square pixels offers a superb image quality. The high-speed shutter function and asynchronous random trigger mode allows the camera to capture high quality images of fast moving objects.
The color version BB-141GE, based on CCD sensor with primary RGB Bayer mosaic filter, outputs raw Bayer images. The JAI Camera Control Tool included in JAI SDK provides color interpolation to display or save color images. The camera features a built-in white balance, eliminating the need for performing this function in the host-PC.
The BM-141GE/BB-141GE also complies with the GenICam standards, as it has an internal XML file that is used to describe the functions/features of the camera. For further information on
GenICam please go to www.emva.org
As an application programming interface, JAI provides an SDK (Software Development Kit).
This SDK includes GigE Vision Filter Driver, JAI Control tool, software documentation and code examples.
The JAI SDK can be downloaded from www.jai.com.
The latest version of this manual can be downloaded from www.jai.com

On the above block diagram, Trigger 0 is used for Exposure and Trigger 1 is used for Delayed
Readout. The Time Stamp Reset can reset the time stamp compliant with GigE Vision standard. This is used for ensuring the same time stamp if multiple cameras are used.
The blocks shown in the above diagram have the following functionalities:
GPIO Port 2
GPIO Port 3

BM-141GE / BB-141GE
6.1.1 LUT (Cross Point Switch)
The LUT works as a cross-point switch which allows connecting inputs and outputs freely. The signals LVAL_IN, DVAL_IN, FVAL_IN and EEN_IN all originate from the camera timing circuit.
On this diagram, Trigger 0 is used for exposure and Trigger 1 is used for Delayed Readout.
The Time Stamp Reset signal can reset the time stamp specified in GigE Vision Format. This signal can be used when time stamps from several cameras connected are coincident with each other.
Outputs from LUT described in the blue line block shows GPIO settings for LINE SELECTOR on
JAI Camera Control tool and inputs for LUT on the left side shows GPIO settings for LINE
SOURCE on JAI Camera Control tool right. Refer to Chapter 6.3 GPIO inputs/Outputs table.
6.1.2 12-bit Counter
The camera pixel clock can be used as a source. The counter has a “Divide by N”, where N has the range 1 through 4096, allowing a wide range of clock frequencies to be programmed.
Setting Value 0 is bypass, setting value 1 is 1/2 dividing and setting value 4095 is 1/4096 dividing. The pixel clock for BM-141GE/BB-141GE is 58 MHz.
6.1.3 Pulse Generators (0 to 1)
Each pulse generator consists of a 19-bit counter. The behavior of these signals is defined by their pulse width, start point and end point.
The pulse generator signals can be set in either triggered or periodic mode.
In triggered mode, the pulse is triggered by the rising edge/falling edge/high level or low level of the input signal. In periodic mode, the trigger continuously generates a signal that is based on the configured pulse width, starting point and end point.
Each pulse generator operates at the frequency created in the 12-bit counter. As the pixel clock (58 MHz) is used as the main frequency, the frequency of pulse generator is 58MHz to
31.693 KHz.
6.2 Opto-isolated Inputs/Outputs
The control interface of the C3 GigE Vision camera series has opto-isolated inputs and outputs, providing galvanic separation between the camera's inputs/outputs and peripheral equipment.
In addition to galvanic separation, the opto-isolated inputs and outputs can cope with a wide range of voltages; the voltage range for inputs is +3.3V to +24V DC whereas outputs will handle +5V to +24V DC.

6.4.3 Pulse generators (19 bit x 2)
There are 2 pulse generators (designated 0 through 1) that can be used to create various timing scenarios by programming start point, endpoint, length and repeats.
The following drawing is an example of settings.
FVAL is used for the input of a pulse generator 0 and the clock after the rising edge of FVAL counts 100 clocks for the high period of the pulse and 102 clocks for the pulse length.
As 2400 is for Clock Pre-scaler, the output of 12 bit counter is 25 KHz, which is 40µs.
The pulse generator o creates a 4 ms pulse.

BM-141GE / BB-141GE
8. Functions and Operations
8.1. GigE Vision Standard Interface
The BM-141GE and BB-141GE are designed in accordance with the GigE Vision standard.
Digital images are transmitted over Cat5e or Cat6 Ethernet cables. All camera functions are also controlled via the GigE Vision interface.
The camera can operate in continuous mode, providing an endless stream of images. For capturing individual images related to a specific event, the camera can also be triggered. For precise triggering, it is recommended to use a hardware trigger applied to the Hirose 12-pin connector. It is also possible to initiate a software trigger through the GigE Vision interface.
However, when using software trigger, certain latency inherent to the GigE interface must be expected. This latency, which manifests itself as jitter, greatly depends on the general conditions and traffic on the GigE connection. The frame rate described in this manual is for the ideal case and may deteriorate depending on conditions.
When using multiple cameras (going through a switch and/or a single path) or when operating in a system with limited transmission bandwidth the Delayed Readout Mode and Inter-Packet
Delay functions can be useful.
8.2. Recommended Network Configurations
Although the BM-141GE and BB-141GE conform to Gigabit Ethernet (IEEE 802.3) not all combinations of network interface cards (NICs) and Switches/Routers are suitable for use with the GigE Vision compliant camera.
JAI will endeavor to continuously verify these combinations, in order to give users the widest choice of GigE components for their system design.

Minimum PC requirements are as follows in order to fulfill the above conditions:
♦ Intel Core 2 Duo , 2.4 GHz or better
♦ At least 2 GB memory
♦ Video Card with PCI Express Bus x 16, VRAM better than DDR2 with 256 MB or more, and display capability of 2560 x 1600
♦ Windows XP, SP2 (32bit)
♦ Functions such as Screen saver and Power save should not be used. Unnecessary applications such as Word, Excel or others should not be used.
Note: Pentium 4 type PC is not recommended due to dependency on chip set bus performance.

♦ In the case of using Jumbo Frames, the packet data will be improved by 2 %.
♦ For BM-141GE and BB-141GE, the jumbo frame size can be a maximum 16384 Bytes (factory setting is 1428 Bytes). The NIC must also be set to support Jumbo Frames(see chapter 8.2.4).
♦ Based on the Pixel Type, the packet size may be automatically adjusted inside the camera to its most suitable value .
To ensure the integrity of packets transmitted from the camera is recommended to follow these simple guidelines:
1. Whenever possible use a peer-to-peer network.
2. When connecting several cameras, going through a network switch, make sure it is capable of handling jumbo packets and that it has sufficient memory capacity.
3. Configure inter-packet delay to avoid congestion in networks switches.
4. Disable screen saver and power save functions on computers.
5. Use high performance computers with multi-CPU, hyper-thread and 64-bit CPU, etc.
6. Only use Gigabit Ethernet equipment and components together with the camera.
7. Use at least Cat5e and preferably Cat6 Ethernet cables.
8. Whenever possible, limit the camera output to 8-bit.
25
BM-141GE / BB-141GE
Note for setting packet size
The packet size is set to 1428 as the factory default. Packet size can be modified in the
GigE Vision Transport Layer Control section of the camera control tool (see below). For
BM-141GE and BB-141GE, users may enter any value for the packet size and the value will be internally adjusted to an appropriate, legal value that complies with the GenICam standard. Thus, the actual packet size may be different than the value entered by the user.
Caution: do not set the packet size larger than the maximum setting available in the NIC or switch to which the camera is connected (see section 8.2.4). Doing so will cause output to be blocked.
Regarding data transfer rate, a larger packet size produces a slightly lower data transfer rate. BM-141GE and BB-141GE can support a maximum of 16384 byte packets provided the
NIC being used has a Jumbo Frames function with a setting of a 16384 bytes or larger.

8.2.7 Calculating and setting Inter-Packet Delay
When connecting several cameras to one network interface card via a switching hub, it is important to optimize the Inter-Packet Delay of the cameras to avoid congestion in the switch.
A sure sign of congestion is the loss of packets.
Since increasing the inter-packet delay also adds overhead to the data transfer it is important to calculate the optimal setting in order to make best use of the video bandwidth.

♦ If it is not shown, confirm the setting as click “Settings Tub“.
8.2.9 Others
♦ IF “Receive Descriptor” is set at its maximum value, picture disturbance may occur due to “Hyper Threading“ mode. If it happens, check that “Hyper Threading“ is set at
OFF. This is set in BIOS.
♦ When the image is being captured, if the frame rate is decreased, change the packet size. Each packet contains the header data and when the packet size is small, the total data including header information will increase. Depending on the performance of the computer used, the frame rate may be decreased. Confirm the packet size is increased. It can be set on Camera Control Tool provided in JAI SDK.
8.2.10 Note for 100BASE-TX connection
♦ In order to use 100Mbps network, 100BASE-TX and Full Duplex are available. Half
Duplex cannot be used.
♦ In the case of connecting on 100BASE-TX, the maximum packet size should be 1500 byte.
♦ In the case the of connecting on 100BASE-TX, the specifications such as frame rate, trigger interval and so on described in this manual cannot be satisfied.

8.3. Basic functions
The BM-141GE and BB-141GE cameras are progressive scan cameras with 12, 10 or 8-bit video output in Gigabit Ethernet. The camera has 1/2, 1/4 or 1/8 partial scanning for faster frame rates. Vertical binning and Draft mode are also available.
The camera can operate in continuous mode as well as in 6 triggered modes:
- Edge Pre-select Trigger
- Pulse Width Control Trigger
- Reset Continuous Trigger
- Smearless EPS Trigger
- Sequential EPS Trigger
- Delayed readout EPS Trigger
- Delayed readout PWC Trigger
(EPS)
(PWC)
(RCT)

Depending on the timing of the trigger input in relationship to FVAL (camera internal Frame valid clock), the start of exposure can be immediate (no-delay, LVAL asynchronous) or delayed until next LVAL (LVAL synchronous).
In the following section the functions are described in detail.
8.3.1 Vertical Binning (BM-141GE only)
The binning functions can be used to achieve higher frame rate or higher sensitivity. The drawback is lower resolution.
Vertical binning is done by adding the charge from pixels in adjacent lines in the horizontal
CCD register. Fig.12 shows the vertical binning principle.

FVAL Timing
Line # from FVAL triming
BB-141GE is a color camera based on a CCD sensor with a Bayer RGB color mosaic.
The color image reconstruction is done in the host PC.
The Color sequence in the video signal is the same for all scanning formats.
The line readout follows LVAL.
The first valid pixel is the same timing as DVAL.
The Bayer color sequence starts with:
• RGR for odd line numbers.
• GBG for even line numbers.
Figure 13 shows the timing sequence for the Bayer mosaic read-out for the available partial scan modes.

8.3.3 Partial Scanning (Fixed rate and variable)
The partial scanning function uses the middle of the image vertically to achieve faster frame rate. This is very useful when capturing and inspecting the image which does not require the height. BM-141GE/BB-141GE has 4 types of partial scan modes such as 2/3, 1/2, 1/4 an 1/8.

In addition to the mentioned fixed rate partial scan modes, BM/BB-141GE has variable partial scan mode. The start line can be set from 1st line to 1025 line and the scanned lines can be set from 8 lines to 1032 lines. Please note that if the odd line is selected as the start line, the Bayer color sequence is RGR and if the even line is selected, it is GBG.

8.3.4 Decimation Readout (Draft) mode in vertical direction(BB-141GE only)
BB-141GE is equipped with the draft mode in vertical direction instead of vertical binning function. 2 lines (RG line and GB line) out of every 8 lines in BB-141GE are thinned out to be read out. The angle of the view is not changed but the height of the image is reduced to 1/4.
The frame rate is 101.17 frames per a second.

8.3.5 Electronic Shutter
BM-141GE / BB-141GE have conventional shutter functions as well as the GenICam standard
“Exposure Time Abs” function.
Preset Shutter
9 steps preset shutter are available: OFF (1/30);
1/60,1/100,1/250,1/500,1/1,000,1/2,000, 1/4,000,1/8,000,1/10,000 sec. (See the register map included in the SDK documentation for details how to configure this register - 0xA004)
Programmable Shutter
It is possible to set the shutter speed in the range of 2L to 1052L by 1L unit, in case of Full
Frame operation. When1052L is set, it is the equivalent of “OFF (1/30)“ or33.19ms. (See the register map included in the SDK documentation for details how to configure this register -
0xA008)

Pulse Width Control
When this mode is selected, the exposure time is controlled by the width of the trigger pulse.
The minimum trigger pulse width is equal to 2L (63µs) and the maximum is 2 seconds.
37
BM-141GE / BB-141GE
Exposure Auto Continuous (Auto Shutter)
In this mode, the shutter continuously functions in the range of OFF to 1/500 s.
Exposure Time Abs (GenICam Standard)
This is a function specified in the GenICam standard.
The shutter speed can be entered as an absolute exposure time in microseconds (μs) in register address 0xA018. The entered absolute time (Time Abs) is then converted to programmable exposure (PE) value inside the camera.
The below calculating formula shows the relationship between the PE value used by the camera for the different readout modes and the value entered in register 0xA018.
Due to round down figure, some errors may occur.
The relation between PE value and Time Abs
Normal readout PE= 2 + INT (Exposure time -63) µs / (1830/58000000)
V Binning readout PE= 2 + INT (Exposure time -75) µs / (2193/58000000)
DRFAT PE= 2 + INT (Exposure time -73) µs / (2139/58000000)
INT means round down.

8.3.6 Auto-Iris Lens video output (12-pin Hirose connector)
This analogue signal is not routed through the GPIO. This signal is available at pin 4 of 12-pin
Hirose connector. It can be used for lens iris control in Continuous mode only.
The signal is taken after the CCD sensor output passes through the gain circuit. The video output is without sync. The signal is 0.7 Vp-p.
To get this signal, the internal DIP switch (SW 601) must be set. Refer to chapter 5.4.

Fig. 16. Iris Video
8.3.7 Full Auto Exposure function
The Full Auto Exposure function combines three automatic functions; Lens Auto Iris, Auto
Gain Control(AGC) and Auto Shutter. When dealing with widely varying lighting conditions, these automatic functions can be made to work in a coordinated fashion to control exposure for a constant video level output. This function makes the BM-141GE and BB-141GE wellsuited for Intelligent Traffic Systems (ITS) and high-end security or surveillance applications.
Full Auto Exposure requires the use of a video controlled auto-iris lens system. The lens should be connected while the power to the camera is OFF.
This Full Auto Exposure function operates as described below.

8.3.8 Auto-detect LVAL-sync / a-sync. accumulation
This function replaces the manual setting found in older JAI cameras. Whether accumulation is synchronous or asynchronous in relationship to LVAL depends on the timing of the trigger input.
When a trigger is received while FVAL is high (during readout), the camera works in LVALsynchronous mode, preventing reset feed-through in the video signal. There is a maximum jitter of one LVAL period from issuing a trigger and accumulation start.
When a trigger is received while FVAL is low, the camera works in LVAL-asynchronous mode,
(no delay) mode.
This applies to both Edge pre-select (EPS) trigger mode and Pulse width trigger (PWC) mode.

8.4. Pre-process functions
BM-141GE/BB-141GE is provided with several pre-processing functions. The output from the camera is selectable to 8, 10 or 12-bit but video is digitized to 14 bits quantization.
The pre-processing functions make use of the 14 bit video. Featured functions are: Bayer color white balance, R/L channel balance, blemish compensation, gain control and LUT (Look
Up Table) for Gamma and Knee correction.
8.4.1 Bayer White Balance (BB-141GE only)
Normally, the raw Bayer color signals are sent to the host as they are. In the host, the signals are interpolated to generate an RGB image and perform white balance.
In order to offload the host, the BB-141GE can adjust Gr, R, Gb and B levels individually to get the white balance for the Bayer output signal. The gain is fixed to 1.0 for BM-141GE.
BB-141GE has Manual white balance, One-push Auto white balance, Continuous Auto white balance and Preset white balance of 3200K, 4600K and 5600K.
Note: Bayer white balance must be set at Normal mode.
8.4.2 Automatic Gain Control
This is the function to keep a constant output level in accordance with ambient brightness changes. The range of AGC as well as manual adjustment is -6dB to 24 dB.
This function set AGC ON or OFF.
Note: This is available only in Normal mode.
41
BM-141GE / BB-141GE
8.4.3 Programmable Look UP table (LUT)
BM-141GE/BB-141GE has a programmable look-up table (LUT) that can be used to adjust the transfer function of the video output. In other words, LUT can be used to create a user defined Knee of Gamma function. In order to get a desired set of characteristics, LUT Values should be set at each LUT Index (0 to 255). For instance, if the gamma is set to 0.45, LUT
Value in the dark portion should be high and it should be smaller as the signal level becomes high. Please refer to the following drawing.

The LUT consists of a data table of each gain which corresponds to all possible CCD outputs. T
In the Control Tool, each LUT Value is displayed as a coefficient (actual LUT value/4096).
Signals multiplied by these LUT coefficients create the desired output signal characteristics.
The look up table has 256 setting points of 14 bits covering the full range of input signals. On each point, the gain can be set to get desired output characteristics. Gr, R, Gb and B signals in BB-500GE have the same characteristics.
The Look Up Table is handled in a 14-bit Video Process circuit and a processed signal is output as a 8-,10- or 12-bit pixel format through GigE interface.

8.4.4 Blemish Compensation circuit
BM-141GE/BB-141GE has a blemish compensation circuit. This function compensates for blemishes on the CCD sensor (typically pixels with extremely high response or extremely low response). This applies to both Monochrome and Color versions. Pixels that fulfill the blemish criteria can be compensated by adjacent pixels on both columns and in case of BB-141GE, the defective pixels can be compensated by adjacent same Bayer color pixels on both columns.
The number of compensations is up to 8 pixels on both L and R channels.
The circuit built in BM-141GE/BB-141GE is ON/OFF function for the compensated data in the factory. The default setting is OFF.

8.6.4 Reset Continuous (RCT) trigger mode
The RCT mode operates like EPS(Edge Preselect)mode with Smearless function. An external trigger pulse will immediately stop the video read out, reset and restart the exposure, then operate as normal mode until the next trigger. After the trigger pulse is input, a fast dump read out is performed. In the BM-141GE and BB-141GE, this period is 6.77ms which is 215L.
The exposure time is determined by the pre-set shutter speed. If no further trigger pulses are applied, the camera will continue in normal mode and the video signal is not output.
The fast dump read out has the same effect as “smearless read out”. Smear over highlight areas is reduced for the trigger frame. The reset continuous trigger mode makes it possible to use triggering in conjunction with a lens with video controlled iris.
To use this mode:

♦ The conditions for this table are that shutter speed should be set the same for all sequences. If the shutter speed is different, the difference of exposure time should be added.
♦ It is recommended to set the exposure time in the order from the shortest to the longer one.
♦ The above table shows the interval at PE=2 (minimum). In case of the longer exposure, the interval is (Value on the table – 2) + Exposure lines.
♦ Do not input the trigger just after the sequence is reset. It requires at least 500ms delay.
♦ ROI can be set by 8 pixels unit in horizontal way. In vertical way, 1 line for B<-500GE and
2lines for BB-141GE can be set for ROI.
8.6.7 Delayed Readout EPS and PWC Modes (EPS and PWC)
This mode can be used to delay the transmission of a captured image. When several cameras are triggered simultaneously and connected to the same GigE interface, it allows the cameras to be read out in sequence, preventing congestion.
The image data is not transmitted directly by the trigger 0 and is stored in the memory located at Ethernet Interface. By the falling edge of the soft trigger 1, the image data is output.
This mode can work in EPS mode and PWC mode.

8.8. Special note for settings
8.8.1 When the image size is changed
When the image size is changed while the image is being capturing, stop the image capturing by pressing “Stop Acquisition”. Then change the value. It is possible to set shutter value and gain settings while watching the picture on the screen.
8.8.2 When the image is captured
While capturing image, if the frame rate is decreased, please check packet size. Each packet has the information called Header. If a packet size is small, total data becomes larger due to increasing of number of headers added to packets. Accordingly, the frame rate is decreased. It is recommended to set the packet size at higher value.
Please note that the packet size is not stored, and it is necessary to set it on every start up. The current frame rate is shown on the bottom of the camera control tool.
8.8.3 Acquisition frame rate
Acquisition frame is a function to set the frame rate of image capturing. The frame rate can be set at full, 1/2, 1/4 and 1/8. This is only useful in “Continuous trigger mode”. If trigger mode is used, it is strongly recommended to use full frame rate. Otherwise, the trigger frequency will also be divided according to the frame rate setting.
Note: The above figure shows an example of BM/BB-500GE.

12.Appendix
12.1. Precautions
Personnel not trained in dealing with similar electronic devices should not service this camera.
The camera contains components sensitive to electrostatic discharge. The handling of these devices should follow the requirements of electrostatic sensitive components.
Do not attempt to disassemble this camera.
Do not expose this camera to rain or moisture.
Do not face this camera towards the sun, extreme bright light or light reflecting objects, including laser sources.
When this camera is not in use, put the supplied lens cap on the lens mount.
Handle this camera with the maximum care.
Operate this camera only from the type of power source indicated on the camera.
Remove power from the camera during any modification work, such as changes of jumper and switch settings.
12.2. Typical Sensor Characteristics
The following effects may be observed on the video monitor screen. They do not indicate any fault of the camera, but do associate with typical sensor characteristics.
V. Aliasing
When the camera captures stripes, straight lines or similar sharp patterns, jagged image on the monitor may appear.
Blemishes
All cameras are shipped without visible image sensor blemishes.
Over time some pixel defects can occur. This does not have a practical effect on the operation of the camera. These will show up as white spots (blemishes).
Exposure to cosmic rays can cause blemishes to appear on the image sensor. Please take care to avoid exposure to cosmic rays during transportation and storage. It is recommended using sea shipment instead of air transportation in order to limit the influence of cosmic rays on the camera.
Pixel defects/blemishes may also emerge due to prolonged operation at elevated ambient temperature, due to high gain setting or during long time exposure. It is therefore recommended to operate the camera within its specifications.
Patterned Noise
When the sensor captures a dark object at high temperature or is used for long time integration, fixed pattern noise may appear in the image.
12.3. Caution when mounting a lens on the camera
When mounting a lens on the camera dusts particles in the air may settle on the surface of the lens or the image sensor of the camera. It is therefore important to keep the protective caps on the lens and on the camera until the lens is mounted. Point the lens mount of the camera downward to prevent dust particles from landing on the optical surfaces of the camera. This work should be done in a dust free environment. Do not touch any of the optical surfaces of the camera or the lens.
