• For maximum efficiency, perform a new DSNU correction
every time the shutter, gain or offset settings are
changed. Generate the image by closing the lens to
eliminate image information.
• DSNU correction feature is not available for the Marlin
F-131C. The FPN correction in former releases of the
Marlin F-131 worked different and is replaced by the
DSNU correction.
• The use of DSNU correction should be accompanied
with shading correction for both low level as well as
high level corrected pixels.
• DSNU and blemish correction are volatile.
