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 inputs and strobe outputs 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.

7 Camera Features
7.1 Area of Interest (AOI)
AOI is the area containing the data required by the user within the entire image. The user can obtain the image
faster than obtaining overall areas by designating the area as AOI while keeping the same high quality. AOI is
determined as the overlapping area of 2 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.
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 frame speed. For more information about AOI parameter settings, see “sha” and “sva” command on
Command List
.

The AOI values (H × V) may vary depending on the type of Camera Link frame grabber.

7.2 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 Binning is applied, but Binning in horizontal
direction does not affect 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.

(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.
7.3.1.1 Free-Run Mode
Free-Run Mode repeats Readout depending on parameter value set in the camera currently, regardless of
trigger input.
Figure 7.6 Free-Run Mode
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 7.7
). In this case, 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 7.8
). In this case, frame speed gets lower as the setting value of Exposure Time increases.

7.3.1.2 Standard Mode
In Standard Mode, the camera keeps standby status until trigger signal is entered, and when trigger input occurs,
Readout start after Exposure process set earlier. After Readout is completed, and returns to trigger standby
status again. In Standard Trigger mode, if a new trigger input occurs during readout, the new trigger input is
ignored.

7.3.1.3 Double Exposure
In Double Exposure mode, 2 images are obtained with 1 trigger input. When trigger input is entered in this mode,
the camera starts Readout after passing through exposure process according to exposure setting as in Standard
mode. At this time, exposure of second image starts with Readout. When Readout is completed, the camera
performs the second Readout. Since it does not generate shutter signal during Readout of the 1st image, the
interval between completion of 1st exposure and starting of 2nd exposure is as short as several ㎲ ~ several
decades ㎲.

7.3.1.4 Fast Mode
Fast Mode is used when interval of trigger input is faster and more continuous than in Standard Mode. Its
difference from Standard Mode is that while Readout starts in exposure time as set earlier when trigger input
occurs in Standard Mode, while Readout immediately starts after trigger input in Fast Mode. And Interval
between triggers becomes the exposure time of image since it does not generate shutter signal during Readout.

7.3.1.5 Overlap Mode
The camera keeps standby status until trigger signal is entered like in Standard Mode, and Readout starts after
exposure process set earlier if trigger input occurs. When new trigger input occurs during Readout of First image,
it keeps Readout and pass exposure process of new trigger input. Provided, however, that when trigger input
occurs during Exposure since Exposure Time is longer than trigger interval, that trigger signal is ignored. To
obtain the image as maximum frame for trigger input, Exposure Time should not be longer than Readout time,
trigger time should not be shorter than Readout time.

T able 7.2 Readout Time for each model
When an acquired image is being readout of the sensor with 4 Tap-I (Sensor Readout: 4 Tap, Data Output: 2 Tap
Interleaved), the entire image will be stored in the buffer before transmitting the image to the frame grabber. This
leads latency (Trd: a half of Readout time).

7.4 Channel Mode
Accumulated charges are read out of the sensor when exposure ends. Te 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
of 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 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 4 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 simultaneously,
is read out with 2 Tap top and bottom or 2 Tap interleaved (Figure 7.16
).
VA-29M supports only 2 Tap top and bottom readout when using the quadrant channel.

7.5 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 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:

LUT (Lookup Table) converts original image value to certain level value. 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
between 0~4095 and provides 2 non-volatile spaces for LUT data storage. User can select whether to apply LUT
or not and where to apply the LUT using “sls” command. See Appendix B

7.7 Defective Pixel Correction
The CCD may have Defective Pixels which cannot properly react to the light. Correction is required since it may
deteriorate the quality of output image. Defective Pixel information of CCD used for each camera is entered into
the camera at the factory. If the user wants to add Defective Pixel information, it is required to enter coordinate of
new Defective Pixel into the camera. See Appendix A
for details. “sdc” command is used to set whether to use
Defective Pixel Correction function.
7.7.1 Correction Method
Correction value Defective Pixel is calculated based on valid pixel value adjacent in the same line.
Figure 7.20 Location of Defective Pixel to be Corrected
If Current Pixel is a Defective Pixel as shown in the above figure, correction value of this pixel is obtained as
shown in the following table depending on whether surrounding pixel is Defective Pixel or not.

7.8 Flat Field Correction
Flat Field Correction is a function which corrects a non-uniform pixel response across a CCD and makes the
response as uniform as possible (flat), assuming the offsets are non-varying (fixed) patterns. The Flat Field
Correction function 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 : Offset 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 environment and activating the Flat Field Generator. The Flat Field Generator will
standardize a series of images, curtailing the image to a ratio of 1/64, 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 Figure 7.22
. When the Flat Field data is generated, use the “sfo”
command to set the M value, and use the “sfc” command to apply the Flat Field Correction. Here, 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. The activation of the Flat Field Generator will ignore the current camera configuration and
will temporarily change the camera configuration to operate under the following default
conditions. When the generation of the Flat Field data is complete, the original setting 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
differently.

7.11 Data Format
Data can be processed in the unit of 12 bit internally, but can be selectively output in the unit of 8, 10 or 12bit at
output. When it is output in 8bit or 10bit unit, the 4 or 2 least significant bits will be dropped from overall 12bits.
Figure 7.23 Data Format (1/2/4 Tap)
In 4 Tap-I (Sensor Readout: 4 Tap, Data Output: 2 Tap Interleaved) mode, image data will be transmitted in the
unit of 8 bit. So, if data format is set to 10 or 12 bit, the 2 or 4 least significant bits will be set to zero.

8.2 Parameter Storage Space
The camera has 3 non-volatile storage space used for parameter storage and 1 volatile work space that is
applied to actual camera operation. 3 storage space is divided into Factory Space that contain basic value at the
factory, and 2 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.
At camera booting, setting value in one of 3 storage spaces is copied to work space according to Config
Initialization value and value of the space is used for camera setting. Since values in work space is valid only
while the power is on, it should be copied to user space 1 or user space 2 using “sct” command.
