FPN correction

3.5.2 FPN correction

The column FPN (fixed pattern noise) correction can be activated or
deactivated. At the beginning of each frame, before visible lines are
read out, a fixed voltage is applied to the columns. If FPN correction
is enabled, this voltage value will be subtracted from each pixel. As a
result the picture will be more homogeneous but has a reduced
dynamic.

FPN correction offers a column correction only. A pixel correction of
the full frame has to be executed by the frame grabber or the imag

-

ing processing software.

NOTE

If the FPN correction of the frame grabber or image

processing software is used, switch off the camera’s

FPN correction. Afterwards, store an image of a

uniform area as a reference and subtract these values

for each pixel of the frame. The noise will disappear.
