6. Input and output circuits
This chapter introduces the basic diagram and bit allocation of digital output.
6.1. Iris video output
+5V
0.1μ
This signal can be used for lens iris control In Continuous and RCT modes. The signal is NUM luminance signal and passes through the gain circuit. However, due to reversed compensation applied, the gain settings do not influence this signal. The iris video output is 0.7 V p-p from 75 and without sync. This signal is always output except EPS and PWC modes.

6.2. Trigger input
When TI=1, the trigger input is on pin #10 on the 12-pin connector. The input is AC coupled. To allow a long pulse width, the input circuit is a flip-flop, which is toggled by the negative or positive differentiated spikes caused by the falling or rising trigger edges.
The trigger polarity can be changed by TP=1.

7. Functions and Operations
7.1. Basic construction
A 32-bit micro processor controls all functions in the AT-200CL camera. The CCD sensor output is normalized in CDS and preamplifiers. The signals are then digitized to 14 bits.
Digital gain control, color matrix, look-up tables and setup can do signal processing in 14 bits before the signal is converted to a 12-, 10- or 8-bit Camera Link signal.

7.2. Main functions
7.2.1 Partial scan (SC)
The partial scanning function uses the middle of the image vertically to achieve faster frame rates. This is very useful when capturing and inspecting an image which does not require the full height. The AT-200CL has 4 types of pre-set partial scan modes: 2/3, 1/2, 1/4 and 1/8.

Fig.13 Partial scan (pre-set)
In addition to pre-set partial scan modes, the AT-200CL has a variable partial scan mode. The start line can be set from the 1st line to 1236th line and the end line can also be set from the
1st line to the 1236th line. In actual use, the start line should always be set smaller than the end line and the end line should be larger than the start line. For instance, if the end line is set at 1236, the start line should be 1235 or smaller. If the start line is set at 1, the end line should be set at 2 or larger.

Fig.14. Variable Partial scan
How to calculate total line number and frame rate in variable partial scan mode
Frame rate (fps) = Horizontal frequency(25.432KHz) / Total lines
Total lines = OB period + Fast Dump period in the upper part of the frame (L) +
Effective image period (L) + Fast dump period in the lower part of frame(L)
+ Blank period (L)
Where,
OB period = 4L (Fixed)
Blank period = 5L (Fixed)
Fast dump period for the upper part = Round up (
5+Start line−1
Fast dump period for the lower part = Round up (
7
1236−End line+2
7
Calculation example
Read out: 1/2 partial at the center (621L), Start line (308), End line (928)
OB period = 4L
) + 1
)
Blank period = 5L
Fast dump period for the upper part = (5+308-1) ÷7 +1= 44.57 + 1 = 45.57 46
Fast dump period for the lower part = (1236-928+2) ÷ 7 =44.2 45
Total lines = 4+5+46+621+45=721
Frame rate = 25,432/ 721 =35.27 fps

AT-200CL
7.2.2 Vertical Binning (VB)
Vertical Binning mode is a function where the signal charges from 2 adjacent (vertical) pixels are added together and read out as one pixel. Binning results in half vertical resolution but higher frame rate and sensitivity. The charge accumulated in 2 adjacent lines is added together in the horizontal CCD register. This is done by providing two pulses to the vertical
CCD register for each line read out. Vertical binning cannot be used together with partial scanning.

7.2.3 Electronic shutter (SM)
The AT-200CL has the following shutter modes.
Pre-set shutter(SH)
The setting command is from SH=0(OFF) to SH=11(1/51,000)
OFF(1/20),1/60,1/100,1/120,1/250,1/500,1/1000,1/2,000,1/4,000,1/7,000,1/17,000 and
1/51,000s
Note: The actual exposure uses the programmable exposure (PE) method. When the camera receives a pre-set shutter value, it is converted to a programmable value inside the camera. So, the actual exposure might be slightly different from the pre-set value.
Programmable Exposure (PE)
The setting command is PE and the exposure time can be controlled from 0L to 1252L in 1
LVAL units (39.32µs). Calculating actual shutter speed requires adding 0.5L to the setting value. This is because there is 0.5L overhead.
The resulting range is from 0.5LVAL to 1252LVAL. Setting 1252L is Shutter OFF.
The programmable exposure can be set for R, G and B together (SM=1) or individually (SM=2) in EPS mode.

Auto shutter
AT-200CL has an automatic shutter function which sets the video at an appropriate level depending on illumination.
Auto shutter range: 1/20 sec to 1/2400 sec
7.2.4 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 relation 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 during FVAL low, the camera works in LVAL-asynchronous mode (no delay) mode.
This applies to both Edge Pre-select (EPS) trigger mode and Pulse Width Control (PWC) trigger mode.
External Trigger

+/- 1 LVAL
(3)
FVAL
(1) In this period camera executes trigger at next LVAL (prevents feed-through noise)
(2) Avoid trigger at FVAL transition (+/- LVAL period), as the function may randomly
switch between “ next LVAL ” and “ immediate ”.
(3) In this period, camera executes trigger immediately ( no delay).

AT-200CL
7.2.5 Shading compensation (SDM)
The AT-200CL implements a digital shading compensation circuit for the white shading which could be caused in the prism or optical system. The whole image is divided horizontally and vertically and uses the center level as the reference. The circuit will compensate the difference between the center and each divided area. The range for compensation is a maximum of
30%.
Shading correction mode: SDM
0:OFF, 1:Factory shading, 2:User 1, 3:User2
These are used to load the stored data.
Fig.17 Shading compensation
In order to calibrate the shading, use RS command, Recalibrate Shading correction.
Param. 1 is used to store the calibration data in 0 for User 1 and 1 for User 2. User 1 and User
2 can store only one data set for either color shading or flat shading. Param. 2 can be set to
0 for Flat or 1 for Color and executes the shading correction and the storing of data.
Note: Conditions for lens used with AT-200CL
In order to get an appropriate picture, it is recommended to use 1/2 inch, 3CCD lenses.
Shading is dependent on F value and focal length. Using a wide angle lens or using the lens fully open, will cause the shading characteristics to deteriorate.
AT-200CL has two shading compensation circuits.
1. Color shading compensation
In this mode, the shading is compensated using the G channel as the reference.
Adjust R and B channels to match the characteristics of the G channel. Use white balance to match R, G and B levels.
Fig.18 Conceptual drawing for color shading compensation
2. Flat shading compensation
In this mode, each channel can be adjusted to achieve flat characteristics.
Fig.19 Conceptual drawing for flat shading compensation

AT-200CL
7.2.6 White balance (WB)
The AT-200CL has 4 white balance modes: manual balance, one push auto white balance, continuous auto white balance and pre-set white balance.
The pre-set white balance can be set to 3200K, 4600K or 5600K.
The white balance of AT-200CL is set under 7500K lighting in factory. If the camera is started up at the first time, it is 7500K white balance and R and B gain settings are 0.
For executing the white balance, the entire image is divided into 64 areas, 8 for horizontal and 8 for vertical. The following drawing is an example of using a 2 x 2 area in the image center.

Note: In continuous mode, if the white part is not enough to make an adjustment, the white balance may not achieve a proper white color.
Note: The completion of one push auto white requires a maximum of 5 seconds to complete.
7.2.7 Linear matrix (CMTX)
The AT-200CL incorporates a linear color matrix circuit to improve color reproduction.
As this circuit processes signals in the linear stage which is before the gamma correction circuit, the gamma circuit does not affect color reproduction.
This circuit has:
1. Linear OFF
2. sRGB Standard which HP and Microsoft specify for printer and monitor. This preset is based on this standard.
3. Adobe RGB Standard which Adobe systems specify. This preset is based on this standard.
4. User User can manipulate R, G and B color relationships based on applications. Set
the gain for R-R, R-G, R-B, G-R, G-G, G-B, B-R, B-G, B-B to adjust.
Important Note:
If sRGB or Adobe RGB is used, please note the following procedure.
1) Achieve the white balance under the condition of D65 (6500K) illumination.
2) Gamma should be set at 0.45 and set the linear matrix at either sRGB or Adobe RGB.
3) Monitor should comply with sRGB or Adobe RGB color reproduction capability.

7.2.9 Knee compensation (KN)
If the relation of input and output is linear (1:1), the output signal is saturated at a certain level of the input signal and details cannot be reproduced in the saturated area. The knee compensation circuit maintains linear output up to a knee point and compresses the level after the knee point. This is set by a knee slope function. AT-200CL supports up to
200% signal compression by knee slope. Factory default is OFF.

9.4. Reset Continuous Trigger (RCT)
The RCT mode operates like EPS (Edge Pre-select) 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 AT-200CL, this period is 7.08ms which is
180L. 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.
RCT mode is available only in LVAL asynchronous.

9.5. Smearless mode
This function can be used to reduce the smear coming from bright parts of the object. This is effective for both EPS and PWC trigger modes. Before the accumulation starts, charge that is stored in the pixel is dumped by a high-speed transfer. This can reduce the smear at the upper part of the object but the lower part is unaffected.
At the falling edge of the trigger pulse the high speed transfer starts. This period is 7.08ms which is 180L. Thereafter the residual charge in the horizontal CCD register is read out in 1L and the new exposure starts. This function is available for both full scan and partial scan.

AT-200CL has a trigger mask function. When this is ON, triggers which are input in shorter intervals than the minimum interval, are disabled. Refer to each trigger mode for information about minimum intervals.

14. Appendix
14.1. 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.
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.
Power off the camera during any modification such as changes of jumper and switch setting.
14.2. 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 CCD 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 flight in order to limit the influence of cosmic rays on the camera.
Pixel defects/blemishes also may 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 on the video monitor screen.
14.3. Caution when mounting a lens on the camera
When mounting a lens on the camera dust 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.
