Shading Correction
The ShadingCorrection function corrects non-uniformity (i.e., shading) in the amount of light
generated by the lens and lighting equipment. Using this function allows correction even if top,
bottom, left, and right shading is not symmetrical in relation to the center of the screen (H, V).
Block size is 256 x 256 pixels.
The following shading correction modes are available on the camera.
FlatShading (Monochrome Model, Color Model)
Correction is performed using the area of the screen with the highest brightness level as the
reference, and adjusting the brightness levels of the other areas to match this level.
ColorShading (Color Model Only)
R-channel and B-channel properties are adjusted to using the G-channel shading properties as a
reference.
Caution •
This camera does not support shading correction after an ROI has been
specified. If the ROI function is to be used, you should first perform shading
correction on the full image, then configure the ROI settings.
•
For FlatShading and ColorShading, the maximum amount of correction gain
for all pixels is limited to 8 times the amount of gain before correction. (The
amount of gain cannot be increased to more than 8 times the amount of
gain from before correction.)
•
If the area in the screen with the highest brightness level is 175 LSB or less
(during 10-bit video output), proper correction is not possible.
