Description of the data path
After the lens has been focused again the image below will be seen, but now with
a considerably more uniform gradient. This is also made apparent in the graph
on the right.
Note
• The calculation of shading data is always carried out at
the current resolution setting. If the AOI is later larger
than the window in which correction data was calculated,
none of the pixels lying outside are corrected.
• For Format_7 mode, it is advisable to generate the shad-
ing image in the largest displayable frame format. This
ensures that any smaller AOIs are completely covered by
the shading correction.
• The automatic generation of shading data can also be
enabled when image capture is already running. The cam-
era then pauses the running image capture for the time
needed for generation and resumes after generation is
completed.
• CCD models only: Shading correction can be combined
with the Image mirror, binning and gamma functionality.
Changing binning modes involve the generation of new
shading reference images due to a change in the image
size.
• CMOS models only: Using shading correction in combi-
nation with the gamma feature on the CMOS models may
lead to improper results.
