Description
FPN and flat field coefficients
enabled.
Reset all FPN to 0 and all flat field
coefficients to 1.
Different user set loaded
depending on direction.
When flatfieldCorrectionMode is
set to ScanDirectionControlled
this feature selects the UserSEt (1
to8) which will be used for the
reverse scan direction.
Selection between two different
flat field algorithms.
Direct calculation of coefficients
based on average line values and
target. First each color is flat
fielded to its peak value and then
the color gains are used to achieve
the target.
A low pass filter is first applied to
the average line values before
calculating the coefficients. Use
this algorithm if the calibration
target is not uniformly white or it
is not possible to defocus the
image. Because of the low pass
filter this algorithm is not able to
correct pixel-to-pixel variations
and so it is preferable to use the
"Basic" algorithm.
A target value between 0 and 255
used by the flat field algorithm.
Sets the number of lines to be
averaged during a flat field
calibration
Set the starting point of a region
of interest where a flat field
calibration will be performed
