FPN and flat field coefficients

Reset all FPN to 0 and all flat field
coefficients to 1.
Selection betw een tw o d ifferent
flat field algorithm s.
Direct calcu lation of coefficients
based on average line valu es and
target. First each color is flat
field ed to its p eak valu e an d then
the color gains are u sed to achieve
the target.
A low p ass filter is first ap p lied to
the average line valu es before
calcu lating the coefficients. Use
this algorithm if the calibration
target is not u niform ly w hite or it
is not p ossible to d efocu s th e
im age. Becau se of the low p ass
filter this algorithm is not able to
correct p ixel-to-p ixel variations
and so it is p referable to u se the
―Basic‖ algorithm .
