perform FPN correction, you can partially remove FPN by
adjusting the digital offset.
Syntax:
sdo t i
Syntax Elements:
t
Tap selection. Allowable range is 1 to 2 depending on
camera model, or
0 for all taps.
i

•
When subtracting a digital value from the digital video
signal, the output can no longer reach its maximum unless
you apply digital gain using the
