5.3 Camera Block Diagram
Figure 5.1 VP Camera Block Diagram
All controls and data process ing of VP cameras are carr ied out in one FPGA chip. The FPGA generally consists
of 32 bit RICS Micro-Controller and Processing & Control logic . The Micro-Controller receives comm ands from
the user through the Camera Link inter face and then processes them . The F PGA controls the Timing Generat ors
(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. Furt hermore, SDRAM and FLASH i s installed outside FPGA. SDRAM is used for the f rame
buffer to process images and FLASH contains the firmware that operates the Micro-Controller. And, Peltier
Driver is applied to control Thermoelectric Peltier Cooling unit.

7 Camera Features
7.1 Area Of Interest (AOI)
AOI is th e area contai ning the data re quired by the user within the entire im age. The user can obt ain the image
faster than obtaining overall areas b y 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 igno red
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 fram e speed will be. Ho wever Horizontal AOI does not
affect frame speed. For more information about AOI parameter settings, see “sha” and “sva” command on
Command List.
Figure 7.1 AOI
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.

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. The camera applies same Binning Factor (2 or 4) to both
directions in order to keep the percentage of image. 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 m any as Binning Factor if Binni ng is applied, but Binning in horizonta l direction does not
affect frame speed. Binning Factor is set using “sbf” command.
Figure 7.3 2×2 Binning

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

7.3 Trigger
7.3.1 T rigger Input
Trigger mode of the camera is divided into Trigger synchronous mode and Trigger asynchronous mode
(hereinafter “Free-Run mode”) depending on i ts synchroni zation with tri gger input. Trigger s ynchronous m ode 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 operat e the camera in Trigger synchr on ous m ode. In concret e, it is req uir ed
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 para meter value set in cam era currently, regardless of trigger

As shown in the above f igu re, Readout s ectio n overl aps w ith expos ure sec tion of next image i n Free-Run Mode.
At this tim e, the camera operation sli ghtly differs depending on leng th 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 (
6TUFigure 7.6U6T). 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 Read out of next image does not s tart until Exposure Time set elapses e ven if Readout finishes
(
6TUFigure 7.7). In this case, frame speed gets lower as the setting value of Exposure Time increases.

mode. At this time, ex posure of second image starts with Readout. W hen Readout is completed, the cam era
performs the second Re adout. Since it does not gen erate shutter signal during Read out of the 1st image, the
interval between com pletion 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 whi le 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
Camera keeps standby status until trigger signal is entered like in Standard Mode, and Readout starts after
exposure process s et earlier if trigger input occurs. W hen ne w tr igg er i nput occ ur s dur i ng R ea dout of First image,
it keeps Readout and pass expos ure 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 m aximum frame for trigger inp ut, Exposure Time should not be longer than Readout time,
trigger time should not be shorter than Readout time. Readout time for each model is as follows:

7.4 Channel Mode
Accumulated charges are read out of the sensor when ex posure ends. The sensor can be read out in one tap
(single channel), t wo tap (d ual channel) or f our tap (qu adrant chan nel - VP-8MC and VP-29MC only). In case of
one tap output, all pixe l values of Hor izontal Register are shifted towards the left bottom Video Amplif ier (Video
A). In case of two t ap output, pixe l values from left to the cent er of Horizontal Register ar e shifted towards the
Video A, and pixel values from the right are shifted towards the Video B. In case of four tap output (V P-8MC and
VP-29MC), pixel values of the lower left area are shifted towards the Video A, pixels values of the lower right
area are shifted to wards the Video B, pixel values of the upper left area are shifted towards the Video C, and
pixel values of the up per right area are shif ted towards the Video D. T he advantage of f our 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 lin e-by-line from the upper left corner until the last pixel in the
lower right corner is read out. In dual channe l, image data is read out of Channel A and B simultaneously in
interleaved order. In quadrant channel , image data which is tr ans mitted from Video A, B, C and D simultaneously,
is read out with 2 Tap top and bottom or 2 Tap interleaved (

7.8 Flat Field Correction
Flat Field Correctio n 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 cam era to the env ironm ent and act iva ting the Flat Field Ge nerat or. The Flat Field Gener ator will
standardize a seri es of im ages , curta iling the im age to a rat io of 1/64, gen erate th e cur tailed F lat F ield data, and
store it in the external f rame buffer. When curtailed images are used for corrections, it is expand ed and applied
with a Bilinear Interpolation as shown in
6TUFigure 7.21U6T. When the Flat Field data is generated, use the “sfo”
command to set the M value, and use th e “sfc” command to a pply the Flat Field C orrection. Here, th e Flat Field
data is stored on th e RAM, a volatile memory. In order to reuse the store d 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.

The camera has 3 non-volatile storage space used for parameter storage and 1 volatile work space that is
applied to actual c amera operation. 3 s torage space is divi ded i nto Fac tory Space that co nta in bas ic v alu e a t the
factory, and 2 user space(User Spac e 1, User Space 2) that can save parameter value tem porarily 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 onl y
while the power is on, it should be copied to user space 1 or user space 2 using “sct” command.
