Basic
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 and
then the color gains are u sed to
achieve the target.
Low Pass
Low Pass
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 the
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.
