Rear panel indicator
The rear panel mounted LED provides the following information:
Power Trig LED
Amber: Power connected – initiating OS( approx. 20sec.)
Red: Initiating the application (approx. 10sec.)
Steady green: Camera is operating in continuous mode
Flashing green: Camera is receiving an external trigger
LINK LED
Steady green: 1000 Base-T has been connected
No light: Not connected
ACT LED
Steady Amber:

Note: When the trigger is input in continuous mode, LED is not flashing. The flashing period
does not coincide with the trigger interval.
8.3.2
Test signal generator
The AM-1600GE and the AB-1600GE have the Moving Ramp Scale test pattern generators.
While the test pattern is selected, the video output is disabled. This function does not depend
on the gain and offset. This function can be set by register but the setting is not stored in the
memory.
8.4
Pre-processing functions (overview)
The AM-1600GE and the AB-1600GE have several pre-processing functions. The output from
the camera is selectable from 8, 10 or 12-bit but the internal processing uses 16 bits
quantization to digitize signals. Accordingly, the processing in the 16-bit domain results in a
more precise image. The pre-processing functions include blemish compensation, shading
compensation (including pixel non-uniformity), LUT(Look Up Table) and auto channel balance .
A brief description of each function is included on the following pages.
8.4.1
Blemish compensation (Register 0xA128) (AM-1600GE only)
The AM-1600CL has a blemish compensation circuit which may be set ON or OFF and a blemish
detection function. This function compensates for blemishes on the CCD sensor (typically
pixels with extremely high response or extremely low response). The detection process starts
with black blemishes and then identifies white blemishes. The order of detection cannot be
reversed. This applies to monochrome model only. Pixels that fulfill the blemish criteria can
be compensated by using the adjacent pixel on the left side column as shown in the following
figure.
There is no limit to the number of pixels that can be compensated. As L channel and R
channel images are composed as one image inside the camera, there is also no limitation on L
channel and R channel compensation. When the circuit is set at ON, the default data (factory
setting) can be used. This is OFF when shipped from the factory.

Note: After completing the detection, the camera will run normally.
