Instead of manually setting the digital gain to a specific value, the camera can
determine appropriate gain values. This command calculates and sets the digital gain.
ccg i
i
Calculation target value in a range from 4096 to 16064 DN (14 bit LSB).
The algorithm calculates the gain of the 8
•
target. For adjacent tap 7, the mean of the last 16 pixels are gained to match the
mean of the first 16 pixels of tap 8. This seam matching continues to tap 1. For
adjacent tap 9, the mean of the first 16 pixels are gained to match the mean of the
last 16 pixels of tap 8. This seam matching continues to tap 16.
• To use this command, the CCD shift direction (scd) should be set to forward (0)
or reverse (1).
ccg 12800
This command sets the digital gain.
sg f
f
Gain applied to all taps: -20 dB to +20 dB.
To use this command, the CCD shift direction (scd) should be set to forward (0) or
reverse (1).
sg 10
Sets the current analog gain setting to be the 0 dB point. This is useful after tap gain
matching allowing you to change the gain on all taps by the same amount.
