Description
calcu late PRN U algorithm
cpa
i i
Perform s PRN U calibration accord ing to the selected
algorithm .
The first p aram eter is the algorithm w here
i
is:
1
= This algorithm first ad ju sts each tap ’s analog gain so
that 8-13% of p ixels w ithin a tap are above the valu e
sp ecified in the target valu e p aram eter. PRN U
calibration then occu rs u sing the p eak p ixel in the region
of interest. (Id entical to
ccp
)
2
= Calcu lates the PRN U coefficients u sing the entered
target valu e as show n below :
PRNU Coefficient =
Target
(AVG Pixel Value) - (FPN+
value)
sdo
The calcu lation is p erform ed for all sensor p ixels bu t
w arnings are only ap p lied to pixels in the region of
interest. This algorithm is u sefu l for achieving u niform
ou tp u t across m u ltip le cam eras.
3
= This algorithm inclu d es an analog gain ad ju stm ent
p rior to PRN U calibration. Analog gain is first ad ju sted
so that the peak pixel value in tap’s ROI is w ithin 97 to
99% of the sp ecified target valu e. It then calcu lates the
PRN U coefficients u sing the target valu e as show n
below :
