calcu late cam era gain
ccg
i t i
Calcu lates the cam era gain accord ing to
the selected algorithm .
i
= Calibration algorithm to u se.
1
= This algorithm ad ju sts analog
gain so that 8% to 13% of tap ROI
p ixels are above the sp ecified target
valu e.
2
= This algorithm ad ju sts analog
gain so that the average p ixel valu e
in tap’s ROI is equal to the
sp ecified target valu e.
3
= This algorith m ad ju sts d igital
gain so that the average p ixel valu e
in tap’s ROI is equal to the
sp ecified target.
4
= This algorithm ad ju sts the
analog gain so that the p eak tap
ROI p ixels are ad ju sted to the
sp ecified target.
t =
Tap valu e. Use
0
