5.3 Camera Block Diagram
Figure 5.1 Camera Block Diagram
All controls and data processing of VA cameras are carried out in one FPGA chip. The FPGA generally consists
of a 32 bit RICS 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 signals 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.

8.1 Area of Interest (AOI)
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 the f igure bel o w. Start point and End
point mean the starting and end of the AOI.
According to characteristics of the sensor structure, readout of the image will be proceeded at the top and
bottom simultaneously. If the Channel mode is set to 4 Tap and Vertical AOI is applied, V End will be ignored
because V End is defined by V Start. The actual V End will be applied according to the following formula:
V End = (VSIZE – V Start) - 1
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.

8.2 Binning
Binning has the effects of increasing the level value and decreasing resolution by adding the values of the
adjacent pixels and sending them as one pixel. VA Series provides four binning factors ( x1, x2, x4, x8) that the
user can apply either vertically, horizontally or in both directions. 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 Binni ng is appl ied , but Binning in hor izo nta l
direction does not affect the frame speed. Binning Factor is set using “sbf” command.

Even if the binning is performed on the color camera, the resulting image will be
monochrome.

8.3 Trigger
8.3.1 T rigger Input
Trigger mode of the camera is divided into Trigger synchronous mode and Trigger asynchronous mode
(hereinafter “Free-Run mode”) depending on its synchronization with trigger input. Trigger synchronous mode is
divided into Standard mode, Double Exposure mode, Fast mode, Overlap mode, depending on concrete
operation type.
It is required to set the trigger first to operate the camera in Trigger synchronous mode. In concrete, it is required
to select which one of CC1 port and TRIGGER_IN port should be used as trigger input and to set whether
polarity of trigger should be Positive or Negative.
8.3.1.1 Free-Run Mode
Free-Run Mode repeats Readout depending on parameter value set in the camera currently, regardless of
trigger input.
As shown in the above figure, Readout section overlaps with exposure section of next image in Free-Run Mode.
At this time, the camera operation slightly differs depending on length of Exposure Time and Readout time. If
Exposure Time is shorter than Readout, Shutter signal occurs during readout, and when Readout finishes,
Readout of next image starts (
Figure 8.7). In this case, the frame speed is constant regardless of change in
Exposure Time. But if Exposure Time is set longer than Readout time, Shutter signal occurs together with start of
Readout and Readout of next image does not start until Exposure Time set elapses even if Readout finishes
(
Figure 8.8). In this case, the frame speed gets lower as the setting value of Exposure Time increases.

8.3.1.2 Standard Mode
In the Standard mode, the camera is in a waiting for trigger acquisition status until trigger signa l is applied.
When a trigger signal is received by the camera, Readout will start after performing Exposure process according
to the setting. After Readout is completed, the camera returns to the waiting for trigger acquisition status and will
remain in that status until a new trigger signal is applied.
In the Standard Trigger mode, if a new trigger signal is applied during the readout process, the new trigger signal
will be ignored.

8.3.1.3 Double Exposure
In the Double Exposure mode, two images are acquired with one trigger signal. When a trigger signal is applied,
the camera starts Readout after performing Exposure process according to the setting as in the Standard mode.
At this time, exposure for the second image starts with Readout for the first image. When Readout for the first
image is completed, the camera performs the second Readout. Since it does not generate shutter signal during
Readout for the first image, the interval between completion of first exposure and start of second exposure is as
short as a few microseconds or dozens of microseconds.

8.3.1.4 Fast Mode
The Fast mode is more useful than the Standard mode when interval of trigger input is relatively fast and
continuous. The difference with the Standard mode is that the Readout immediately starts after a trigger signal is
applied while the Readout starts after performing exposure according to the exposure time setting in the
Standard mode. And the interval between trigger signals is equal to the exposure time for the images since it
does not generate shutter signal during Readout.

8.3.1.5 Overlap Mode
In the Overlap mode, the camera remains waiting for trigger acquisition status until a trigger signal is applied as
in the Standard Mode. When a trigger signal is applied, the Readout starts after performing exposure process
according to the exposure time setting. When new trigger signal is applied to the camera during the Readout
process for the first image, the camera will continue to perform the Readout process while performing the
exposure process for the new trigger signal. However, if the exposure time is longer than the interval of trigger
input and the trigger signal is applied during the Exposure process, the trigger signal will be ignored. To acquire
the image with the maximum frame, the exposure time should not be longer than the readout time and the
interval of trigger input should not be shorter than the readout time.
The readout time for each model is as follows:
Channel Mode VA-1M VA-2M VA-2M (HD) VA-4M VA-8M VA-29M
1 channel 29.3 ms 53.5 ms 56.5 ms 112.8 ms 226.5 ms 763.1 ms
2 channel 15.5 ms 28.0 ms 29.0 ms 59.7 ms 121.9 ms 397.7 ms
4 channel 7.9 ms 14.2 ms 14.7 ms 30.1 ms 61.3 ms 199.6 ms
Table 8.2 Readout Time for each model
When an acquired image is being readout of the sensor with 4 T ap-I (Sensor Readout: 4 Tap, Data Output: 2 Tap
Interleaved), the entire im age will be stored in the buffer before transmitting the image to the frame grabber. This
leads latency (Trd: a half of Readout time).

8.4 Channel Mode
Accumulated charges are read out of the sensor when exposure ends. The sensor can be read out in one tap
(single channel), two tap (dual channel) or four tap (quadrant channel). In case of one tap output, all pixel values
in the Horizontal Register are shifted towards the left bottom Video Amplifier (Video A). In case of two tap output,
pixel values from left to the center of the Horizontal Register are shifted towards the Video A, and pixel values
from the right are shifted towards the Video B. In case of four tap output, pixel values of the lower left area are
shifted towards the Video A, pixels values of the lower right area are shifted towards the Video B, pixel values of
the upper left area are shifted towards the Video C, and pixel values of the upper right area are shifted towards
the Video D. The advantage of four tap output is that it makes readout about four times faster than one tap
output.

The camera processes and rearranges the image data in order to be compliant with the base Camera Link
Standard. In single channel, image data is read out line-by-line from the upper left corner until the last pixel in
the lower right corner is read out. In dual channel, image data is read out of Channel A and B simultaneously in
interleaved order. In quadrant channel, image data which is transmitted from Video A, B, C and D s imultaneously,
is read out with 2 T ap top and bottom or 2 T ap interleaved (
VA-29M supports only 2 Tap top and bottom readout when using the quadrant channel.

8.5 Gain and Offset
The camera has one Analog Signal Processor (or Analog Front End, abbreviated to 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. AFE has a register for Gain and Offset application inside, and can change Gain and Offset value
by entering proper value in the register. Gain can be set between 0 ~ 899. The relationship between setting
value and actual Gain (㏈) is as follows:
Gain(㏈) = (Setting value × 0.035 ㏈)
The available range of offset values is 0 ~ 255 (LSB).

between 0~4095 and VA Camera Link camera provides 2 non-volatile spaces for LUT data storage. You can
determine whether to apply LUT and which LUT to use using “sls” command. For more information about how to
download LUT to the camera, refer to

8.7 Defective Pixel Correction
The CCD may have Defect Pixels which cannot properly react to the light. Correction is required since it may
deteriorate the quality of output image. Defect Pixel information of CCD used for each camera is entered into the
camera during the manufacturing process. If you want to add Defect Pixel information, it is required to enter
coordinate of new Defect Pixel into the camera.
For more information, refer to
Appendix A. “sdc” command is used to set whether to use Defective Pixel
Correction feature.
8.7.1 Correction Method
Correction value for a defect pixel is calculated based on valid pixel value adjacent in the same line.
Figure 8.20 Location of Defect Pixel to be corrected
If current pixel is a defect pixel as shown in the above figure, correction value for this pixel is obtained as shown
in the following table depending on whether surrounding pixel is defect pixel or not .

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 : Average value of image after correction;
IF : Level value of Flat Field data.
In order to use the Flat Field Correction function, one must first generate IF , the Flat Field data. This can be done
by adjusting the camera to the actual environment and activating the Flat Field Generator. The Flat Field
Generator will standardize a series of images, curtailing the image to 1/16 pixel, generate the curtailed Flat Field
data, and store it in the external frame buffer. When curtailed images are used for corrections, it is expanded and
applied with a Bilinear Interpolation as shown in
command to set the M value, and use the “sfc” command to apply the Flat Field Correction. At this time, the Flat
Field data is stored on the RAM, a volatile memory. In order to reuse the stored data, the “sdf” command must
be used to store them on the FLASH, a non-volatile memory.
1. Activating the Flat Field Generator will ignore the current camera settings a nd wil l
temporarily change the camera settings to operate under the following default conditions.
When the generation of the Flat Field data is completed, the original settings of the camera
will be restored.
Readout Mode: Normal
Trigger Mode: Free-Run
Channel Mode: Single
Defective Pixel Correction: ON
2. The offset value M is based on the Normal Readout mode. According to the AOI mode,
Binning mode, or Dual Channel mode, the offset value of an actual image is expressed
Figure 8.22. When the Flat Field data is generated, use the “sfo”
differently.

9.2 Actual Time Applied for Commands
When you execute a command, the actual or real time applied for the command varies depending on the type of
the command and operating status of the camera.
All commands exc ept Se t E x posur e Time (‘set’) com m and are applied to change the settings as i llus tr ated be lo w,
on the rising edge of a VCCD signal before starting readout process.
When you execute a ‘set’ command, the exposure time setting will be changed at the starting of the exposure.
In the Trigger mode, you must execute commands before applying trigger signals in order to synchronize image
outputs with the commands.
In the Free-Run mode, even if you execute a command, you may acquire up to two images without applying the
command. This is true because it is hard to verify the current operating status of the camera in the Free-Run
mode.

9.3 Parameter Storage Space
The camera has three non-volatile storage spaces used for parameter storage and one volatile work space that
is applied to actual camera operation. Three storage spaces are divided into Factory Space that contain basic
value at the factory, and two user space (User Space 1, User Space 2) that can save parameter value
temporarily set by the user. User space can be read and written, but Factory space can be read only.
When the camera is powered on or reset, setting values stored in one of the storage spaces are loaded into the
work space according to the Config Initialization setting and these values will be used for the camera settings.
Since values in the work space are valid only while the power is on, they should be copied to user space 1 or
user space 2 using “sct” command.

10 Configurato r GUI
Configurator, a sample application, is provided to control VA Camera Link series camera. Configurator provides
easy-to-use Graphic User Interface (GUI) for the user while using the commands mentioned in the previous
chapters.
10.1 Camera Scan
When you execute the program while the camera is turned on, the Camera Scan window appears as shown in
the figure below. At this time, the program checks serial port of your computer and DLL provided by the camera
link to scan whether the camera is connected. If there is a camera connected, it displays model name on the
screen. If the camera is not properly displayed on the screen, check the connection of cables and power of the
camera, and press the refresh button. When you double-click a model name displayed on the screen,
Configurator is executed and displays current setting value of the camera connected.
