Calibrating Camera Gain
Pu rp ose:
The cam era can d eterm ine ap p rop riate gain valu es. This
com m and calcu lates the gain requ ired to reach the ou tp u t target
w ith a seam m atching algorithm .
Syntax:
ccg i
Syntax Elem ents:
i
i
Calcu lation target valu e in a range from
4096
to
16064
DN
(14 bit LSB).
N otes:
This fu nction requ ires constant light inp u t w hile execu ting.
To u se this com m and , the CCD shift d irection (
) shou ld
be set to forw ard (
0
) or reverse (
1
).
Perform gain algorithm s before p erform ing FPN and PRN U
calibration.

Updating the Gain Reference
To update the gain reference:
Pu rp ose:
Sets the cu rrent gain setting to be the 0d B p oint. This is u sefu l
after tap gain m atching to allow you to change the gain on all tap s
by the sam e am ou nt.
