5.3 Camera Block Diagram
Figure 5.1 Camera Block Diagram
All controls and data processing of the cameras are carried out in one FPGA chip. The FPGA generally consists
of a 32 bit RISC Micro-Controller and Processing & Control Logic. The Micro-Controller receives commands from
the user through the Camera Link interface and then processes them. The FPGA controls the Timing Generators
(TGs) and the Analog Front End (AFE) chips where the TGs generate CCD control signals and AFE chips
convert analog CCD output to digital values to be accepted by the Processing & Control Logic. The Processing &
Control Logic processes the image data received from AFE and then transmits data through the Camera Link
interface. And also, the Processing & Control Logic controls the trigger input and output signal which are
sensitive to time. Furthermore, SDRAM and FLASH is installed outside FPGA. SDRAM is used for the frame
buffer to process images and FLASH contains the firmware that operates the Micro-Controller.

The Area of Interest (AOI) feature allows you to specify a portion of the sensor array. You can acquire only the
frame data from the specified portion of the sensor array while preserving the same quality as you acquire a
frame from the entire sensor array. AOI is determined as the overlapping area of two areas when designating
start point and end point in horizontal and vertical direction as shown in figure below. Start point and End point
mean the starting and end of the AOI.
The narrower Vertical AOI is designated, the faster the frame speed will be. However Horizontal AOI does not
affect the frame speed. For more information about AOI parameter settings, see “sha” and “sva” command on
Command List.
Figure 8.1 Area of Interest
The AOI values (H × V) may vary depending on the type of frame grabber. For technical assistance, contact to your local dealer or the manufacturer.

8.2 Binning
Binning has the effects of increasing the level value and decreasing resolution by summing the values of the
adjacent pixels and sending them as one pixel. The camera applies the same Binning Factor (2×, 3×, 4×, the
3× binning factor is only available in the VH-11MC camera.) to both directions in order to keep the imaging ratio.
The below figure shows application of 2 × 2 Binning and 4 × 4 Binning respectively. Since Binning in vertical
direction is processed at internal register of CCD, the frame speed increases as many as Binning Factor if
Binning is applied, but Binning in horizontal direction does not affect the frame speed. Binning Factor is set using
“sbf” command.
Figure 8.3 2 × 2 Binning
Figure 8.4 4 × 4 Binning
Even if the binning is performed on the color camera, the resulting image will be monochrome.

8.3 Trigger Mode
When the Trigger Mode is set to Free-Run, the camera will generate all required trigger signals internally, and
you do not need to apply trigger signals to the camera.
When the Trigger Mode is set to Standard, Fast, Double or Overlap, you must apply a trigger signal to the
camera each time you want to begin a frame acquisition. The Source parameter specifies the source signal that
will act as the trigger signal. The available settings for the Source parameter are: CC1: You can apply a trigger signal to the camera via Camera Link CC1 channel.
For more information, refer to your Camera Link frame grabber user manual.
Ext.: You can apply a trigger signal to the camera by injecting an externally generated electrical
signal (commonly referred to as a hardware trigger signal) into the Control I/O receptacle on the camera.
If the Source parameter is set to CC1 or Ext., you must also set the Polarity parameter. The available settings for the Polarity parameter are:
Active Low: Specifies that a falling edge of the electrical signal will act as the trigger signal.  Active High: Specifies that a rising edge of the electrical signal will act as the trigger signal.
Page 35
VH Camera Link series
Page 35 of 84 RA14-132-001
8.3.1 Free-Run Mode
When the Trigger Mode is set to Free-Run, the camera will generate all required trigger signals internally. When
the camera is set this way, the exposure time for each frame acquisition is determined by the value of the
camera’s Exposure Time parameter. The camera will constantly acquire images (repeat exposure and readout)
without any need for triggering by the user.
Figure 8.5 Free-Run Mode
With the Trigger Mode set to Free-Run, the exposure for a new frame will overlap the readout for the previous
frame. The operation of the camera may differ depending on the length of the exposure time and readout time.
Page 36
VH Camera Link series
Page 36 of 84 RA14-132-001
If the exposure time is shorter than the readout time, a shutter signal will be generated while reading out the
sensor data for the previously acquired frame. Then, the camera will begin reading out the sensor data for a new
frame as soon as it finishes reading out the sensor data for the previous frame. In this case, the frame speed will
be constant regardless of changes in the exposure time.
Figure 8.6 Exposure Time is Shorter than Readout Time
If the exposure time is longer than the readout time, the camera will begin the process of reading out a frame
each time a shutter signal is generated. After completing the process of reading out the frame, the camera will
not begin the process of reading out a new frame until the camera completes the process of exposing a new
frame. In this case, the frame speed becomes slower as you increase the exposure time value.
Figure 8.7 Exposure Time is longer than Readout Time
Page 37
VH Camera Link series
Page 37 of 84 RA14-132-001
8.3.2 Standard Mode
When the Trigger Mode is set to Standard, you must trigger exposure start by applying trigger signals to the
camera. Applying a trigger signal to the camera will exit the camera from the waiting for trigger signal acquisition
status and will begin the process of exposing and reading out a frame. After the readout for the frame is
complete, the camera will be operated according to the Frame Number after triggered settings as shown
below. You can set the Frame Number after triggered settings by using the “sfn” command.
0: the camera will be operated in the Free-Run mode. 1: the camera will return to the waiting for trigger signal acquisition status. 2 ~ 255: the camera will return to the waiting for trigger signal acquisition status once the number of
image acquisitions is reached to the setting value minus one.
Figure 8.8 Standard Trigger Mode
Trigger signals applied to the camera when it is not in a waiting for trigger signal acquisition status will be
ignored.
Figure 8.9 Trigger Ignored
Page 38
VH Camera Link series
Page 38 of 84 RA14-132-001
8.3.3 Double Mode
When the Trigger Mode is set to Double, two frames can be acquired with a single trigger signal. When a
trigger signal is applied to the camera, the camera begins the process of exposing the first frame according to
the current exposure time settings. Once the exposure for the first frame is complete, the camera reads out the
sensor data. At this point, the process of exposing the second frame begins. Then, the camera reads out the
sensor data for the second frame after reading out the sensor data for the previous frame.
In the Double mode, the exposure time for the second frame equals to the readout time of the first frame. There
is a just few microseconds (or dozen of microseconds) between the point where the exposure process for the
first frame ends and the point where the exposure process for the second frame begins. This is because the
camera does not generate a shutter signal while reading out the sensor data for the first frame. At this point, the
camera outputs a strobe out signal reflecting the exposure time for the first frame.
Figure 8.10 Double Mode
Page 39
VH Camera Link series
Page 39 of 84 RA14-132-001
8.3.4 Fast Mode
The Fast mode is useful to apply trigger signals with shorter interval than those in the Standard mode. In the
Fast mode, the camera begins the process of reading out the previous frame as soon as a new trigger signal is
applied to the camera. The trigger signal interval determines the exposure time for a frame since the camera
does not generate a shutter signal during the process of reading out a frame.
Figure 8.11 Fast Mode
Page 40
VH Camera Link series
Page 40 of 84 RA14-132-001
8.3.5 Overlap Mode
When the Trigger Mode is set to Overlap, the camera operates in the ‘overlapped’ mode which allows the
exposure for a new frame to overlap the sensor readout for the previous frame. When a new trigger signal is
applied to the camera while reading out the previous frame, the camera begins the process of exposing a new
frame. If you will be operating the camera with the Overlap mode, there are important guidelines to keep in mind:
You must not begin the exposure for a new frame while the exposure for the previous frame is in progress. You must not end the exposure for the current frame until the readout for the previous frame is complete. To acquire images with the maximum frame rate, the exposure time must not be longer than the readout
time and the trigger signal interval must not be shorter than the readout time.
The readout time for each camera model is shown in the following table.

8.4 Channel Mode
The Channel mode determines how image data in the horizontal register of the CCD will be read out. The available settings are: 1 Tap (Single Channel) or 2 Tap (Dual Channel).
With the 1 Tap setting, all pixel values in the horizontal register will be read out from the left bottom Video
Amplifier (Video L). With the 2 Tap setting, pixel values from the left of the CCD will be read out from the Video L
and pixel values from the right of the CCD will be read out from the Video R. The advantage of the 2 Tap setting
is that it makes readout about two times faster than the 1 Tap setting. This is true because the two channels are
used simultaneously to read out the image sensor.

The image data read out from the CCD goes through image processing and it is reordered to be compliant with
the Camera Link standard. With the Single Channel (1 Tap), image data read out from the Video L will be
transmitted in a Camera Link 1 Tap fashion. With the Dual Channel (2 Tap), image data read out from the Video
L and R simultaneously will be transmitted in a Camera Link A, B 2 Tap Interleaved fashion.

8.5 Gain and Offset
The camera has one Analog Signal Processor (or Analog Front End, AFE) for each channel. This AFE consists
of Correlated Double Sampler (CDS), Variable Gain Amplifier (VGA), Black Level Clamp and 12-bit A/D
converter. The AFE has a register for Gain and Offset values. You can change the Gain and Offset values by
entering a proper value in the register. The Gain value can be set in a range from 0 to 899. If you know the
current setting value for the Gain, you can use the formula below to calculate the actual Gain (㏈).

8.6 LUT
LUT (Lookup Table) converts original image values to certain level values. Since it is mapped one to one for
each level value, 12-bit output can be connected to 12-bit input. LUT is in the form of table that has 4096 entries
from 0 to 4095 and the VH Camera Link cameras provide 2 non-volatile spaces for LUT data storage. You can
determine whether to apply LUT and which LUT to use using the “sls” command. For more information about
how to download LUT to the camera, refer to Appendix B.

8.7 Defective Pixel Correction
The CCD may have Defect Pixels which cannot properly respond to the light. The VH Camera Link cameras
provide a feature to correct the defect pixel to enhance the quality of output images. Defect Pixel information of
the CCD used for each camera is saved in the camera during the manufacturing process in the factory. If you
want to add Defect Pixel information, it is required to enter coordinate of new Defect Pixel into the camera.
You can determine whether to use the Defective Pixel Correction feature by using the “sdc” command. For more
information, refer to Appendix A.
8.7.1 Correction Method
A correction value for a defect pixel is calculated based on valid pixel values adjacent in the same line.

8.8 Flat Field Correction
The Flat Field Correction feature improves the image uniformity when you acquire a non-uniformity image due to
external conditions. The Flat Field Correction feature can be summarized by the following equation:
IC = {(IR – IB) × M} / (IF – IB)
Where,
IC: Level value of corrected image
IR: Level value of original image
IB: Black offset value
M: Target value of image after correction
IF: Level value of Flat Field data
8.8.1 Sequence of Flat Field Correction
Under actual use conditions, generate Flat Field data (IF) and enable the Flat Field Correction feature according
to the following procedures.
How to generate Flat Field Correction data using Serial Commands
1. Use the “sfi n” command to set the number of frames (2n) to be used for generating the Flat Field data.
2. Use the “sfo” command to set the target value M to be applied after correction.
3. Use the “gfd” command to execute the Flat Field Generator.
4. Acquire images as many as set in the step 1 by operating the camera in the Free-Run mode or by applying trigger signals to the camera.
5. Use the “sfc” command to enable the Flat Field Correction feature. The Flat Field data will be expanded and then applied as shown in the Figure 8.22.
6. Use the “sfd” command to save the generated Flat Field data in the non-volatile memory.

2. Under the FFC Offset Level category, set the target value M to be applied after correction.
3. Click the Generate button to execute the Flat Field Generator.
4. Acquire images as many as set in the step 1 by operating the camera in the Free-Run mode or by applying trigger signals to the camera.
5. In the VIEW tab, click the Flat Field Corr. check box in the Image Processing category to enable the FFC.
6. In the FFC tab, click the Save to Flash button in the Flash Memory category to save the generated Flat
Field Correction data in the non-volatile memory. The Flat Field data will be expanded and then applied as
shown in the Figure 8.22 when they are used for correction.
Figure 8.20 Flat Field Correction in Configurator
When you execute the Flat Field Generator, the camera will ignore the current settings and
will use the default settings as shown below. After generating the Flat Field data, the
original camera settings will be restored.
Readout Mode: Normal Trigger Mode: Free-Run Channel Mode: Single Defective Pixel Correction: ON
The target value M is based on the Normal Readout mode. The level values on the image
may vary depending on the AOI, Binning or Channel mode settings.

8.9 Temperature Monitor
The camera is equipped with a temperature sensor to monitor the internal temperature. You can check the
temperature of the camera by using the “gct” command.
8.10 Status LED
A green LED is installed on the back panel of the camera to inform the operation status of the camera. LED status and corresponding camera status are as follows:
Continuous ON: operates in the Free-Run mode. Repeat On for 0.5 seconds, Off for 0.5 seconds: operates in the Trigger mode. Repeat On for 1 second, Off for 1 second: outputs Test Image. Repeat On for 0.25 seconds, Off for 0.25 seconds: operates in the Trigger mode and outputs Test Image.
8.11 Data Format
The internal processing of image data is performed in 12 bits. Then, the camera can output the data in 8, 10 or
12 bits. When the camera outputs the image data in 8 bits or 10 bits, the 4 or 2 least significant bits will be
truncated accordingly.

8.12 Test Image
To check whether the camera operates normally or not, it can be set to output test images generated in the
camera, instead of the image data from the CCD. Three types of test images are available; image with different
value in horizontal direction (Test Image 1), image with different value in diagonal direction (Test Image 2), and
moving image with different value in diagonal direction (Test Image 3). The Test Image feature is available in all
operation modes of the camera. You can set the Test Image feature by using the “sti” command.

8.15 Strobe
The camera provides a Strobe output signal. The signal goes high when the exposure time for each frame
acquisition begins and goes low when the exposure time ends. This signal can be used as a flash trigger and is
also useful when you are operating a system where either the camera or the object being imaged is movable.
Typically, you do not want the camera to move during exposure. You can monitor the Strobe output signal to
know when exposure is taking place and thus know when to avoid moving the camera.
8.15.1 Strobe Offset
The Strobe Offset value specifies a delay that will be applied between the point where the shutter signal rises
and the point where the Strobe output signal rises. The width of Strobe output signal will be the same as the
width of exposure but only the point where the Strobe output signal rises is adjusted. You can set the Strobe
Offset in microseconds by using the “sso” command.

8.15.2 Strobe Polarity
The Strobe Polarity is used to select Active High or Active Low triggering. You can set the polarity of the strobe
output signal by using the “ssp” command.
8.16 Field Upgrade
The camera provides a feature to upgrade the firmware and FPGA logic through the Camera Link interface
rather than disassemble the camera in the field. Refer to Appendix C for more details about how to upgrade.

9 Camera Configuration
9.1 Setup Command
You can configure all camera settings via RS-644 serial interface of the Camera Link. When you want to control
the camera using a terminal or to directly access the camera at your application, you need to set your network as
follows:
Baud Rate: 19200 bps Data Bit: 8 bit Parity Bit: No Parity Stop Bit: 1 stop bit Flow Control: None
All camera setting commands are transmitted in the ASCII command type except a command for transmitting a
large file such as firmware download. All camera setting commands are transmitted from the user application
and then the camera returns a response (“OK”, “Error” or information) for a command. When you execute a write
command, the camera returns a response to inform whether the command has been successfully executed.
When you execute a read command, the camera returns an error or information.
Command format:
<command> <parameter1> <parameter2> <cr>
0~2 parameters follow the command.
Response:
- If a write command is successfully executed
OK <cr> <lf>
Ex) Write command
In response to a “set 100” command the camera will return (in hex value)
Command : 73 65 74 20 31 30 30 0D
set 100<cr>
Response : 73 65 74 20 31 30 30 0D 0A 4F 4B 0D 0A 3E

9.2 Actual Time Applied for Commands
When you execute a command, the actual runtime of the command varies depending on the type of the
command and the operating status of the camera.
All commands except Set Exposure Time (‘set’) command are applied to change the settings as illustrated
below, on the rising edge of a VCCD signal before starting the readout process. When you execute the ‘set’
command, the exposure time setting will be changed and applied at the starting of the exposure.
If you operate the camera with CC1 or external trigger signals, you must execute commands before applying the
trigger signals in order to synchronize image outputs with the commands.
If you execute a command in the Free-Run mode, you may acquire up to two images that are not affected by the
command execution. This is true because it is hard to verify the current operating status of the camera in the
Free-Run mode.
Figure 9.1 Actual Time Applied for Commands

VH Camera Link series
Page 59 of 84 RA14-132-001
9.3 Parameter Storage Space
The camera provides three non-volatile spaces for storing parameter settings and one volatile work space. The
work space contains the camera’s current parameter settings. Non-volatile spaces are divided into Factory
Space that contains default values entered during the manufacturing, and two user spaces (User1 Space and
User2 Space) that are available for saving parameter settings by users. Read and write operations are allowed
in the user spaces, but only the read operations are allowed in the factory space.
When the camera is powered on or reset, parameter settings stored in one of the storage spaces are loaded into
the work space according to the Config Initialization value. These parameter settings will then determine the
camera’s performance.
The parameter settings in the work space are lost when the camera is powered off or reset. The camera can
save parameter settings from the work space to a user space in the camera’s non-volatile spaces.
The parameter settings stored in the non-volatile spaces are not lost when the camera is powered off or reset.

10 Configurator GUI
Configurator, a sample application, is provided to control VH Camera Link series cameras. Configurator provides
easy-to-use Graphic User Interface (GUI) that allows users to view and change the camera’s parameter settings
mentioned in the previous chapters.
10.1 Camera Scan
When you execute the Configurator.exe file while the camera is powered on, the Camera Scan window appears
as shown in the figure below. At this time, the Configurator checks serial port of your computer and DLL provided
by the Camera Link to scan whether a camera is connected. If the Configurator finds a connected camera, it
displays the model name of the camera on the Camera Scan window. If the camera is not displayed on the
window, check the cable connections and power of the camera, and then press the refresh button.
Double-clicking the model name of the camera displayed on the window will launch the Configurator and display
the current parameter settings of the camera connected.
