Shading Correction
Related Setting Items:
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).
This function can be used even when the effective image area is limited (an area with both Width and
Height set to more than 128 must be configured) by the ROI function. In such cases, the correction
area is included in the image area configured by the ROI.
See the table below for the block size information for a full image. The ineffective peripheral areas will
be deleted internally on the camera automatically.
