Important note:
•
Depending on the optics and/or illumination used together with the camera, it may not
be possible to fully compensate for shading.
Operating procedure for individual R, G and B channel shadings correction:
1. Before making adjustment,
it is required approximately 30 minutes warming up.
2. Make sure the output signal is not saturated (80% of full output is recommended)
3. Set command PGC=2 and SDC=2.
4. Set command SDR to 0 to initiate shading correction.
5. If desired, set command PGR to 0 to activate flat-field (pixel gain) correction to
correct for pixel response non-uniformity.
6. Again set SDR=0 after running the flat-field (pixel gain) correction
(B) Chromatic shading correction (SDR=1)
In this mode, shading correction of R and B signals is referenced to the G signal which is the
reference. When the Green channel detects “undulating” or “parabolic” type shading, R
and B channels are compensated to follow the same curve.
The calculation is based on the average value of 8 consecutive pixels
Important Note:

For this function, no reference value is stored in the camera.
