Analog Signal Processing: Setting Analog Gain and Offset
All analog signal processing chain commands should be performed prior to FPN and
PRNU calibration and prior to digital signal processing commands. All digital processing
(digital offset, pixel coefficients, background subtract and digital gain) should be disabled
prior to performing analog processing. To disable digital processing, send the following
commands:
sdo 0 0
,
epc 0 0
,
ssb 0 0
,
ssg 0 4096
.
Setting Analog Gain
Purpose: Sets the camera’s analog gain value. Analog gain is multiplied by
the analog signal to increase the signal strength before the A/D
conversion. It is used to take advantage of the full dynamic range
of the A/D converter.
