    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. Mode...

    2:1 V Binning 618 / 628 22.563 KHz 35.93 frames /sec. 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.

  • Page 20: Shading Compensation (Sdm)

    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.

  • Page 21: White Balance (Wb)

    The pre-set white balance can be set to 4000K, 4600K or 5600K. The white balance of AT-200CL is set under 7800K lighting in factory. If the camera is started up at the first time, it is 7800K white balance and R and B gain settings are 0.

    AT-200CL 9.2. Edge Pre-select Trigger Mode An external trigger pulse initiates the capture, and the exposure time (accumulation time) is the fixed shutter speed set by SH or PE. The accumulation can be automatically set either LVAL synchronous or LVAL asynchronous in relation to FVAL and trigger timing.

    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.
