Calibration algorithm to u se.
1
= This algorithm ad ju sts analog gain so
that 8% to 13% of tap region of interest
(ROI) p ixels are above the sp ecified target
valu e.
2
= This algorithm ad ju sts analog gain so
that the average pixel value in tap’s ROI is
equ al to the sp ecified target valu e.
3
= This algorithm ad ju sts d igital gain so
that the average pixel value in tap’s ROI is
equ al 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.

Tap valu e. Use
0

1

i
Calcu lation target valu e in a range from
1024
to
4055
DN (12 bit LSB).
This fu nction requ ires constant light inp u t w hile
execu ting.
If very few tap p ixels are w ithin the ROI, gain
calcu lation m ay not be op tim al.
When all tap s are selected , tap s ou tsid e of the
ROI are set to the average gain of the tap s that
are w ithin the ROI.
Perform analog gain algorithm s before
p erform ing FPN and PRN U calibration.
All d igital settings affect the analog gain
calibration. If you d o not w ant the d igital
p rocessing to have any effect on the cam era gain
calibration, th en tu rn off all d igital settings by
send ing the com m and s:
sdo 0 0
,
epc 0 0
,
ssb 0 0
, and
ssg 0 4096

Setting Analog Offset
Sets the analog offset. The analog offset shou ld be set so that it is at least 3 tim es the rm s noise valu e at
the cu rrent gain. Teled yne DALSA configu res the analog offset for the noise at the m axim u m sp ecified
gain and as a resu lt you shou ld not need to a d ju st the analog offset.
