ShadingCorrection
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.
SP-12401M-USB
For a full image, the number of correction blocks is 17 (H) × 12 (V) blocks and calculation
errors in the correction data are minimized due to the small interpolation areas. Each block is
256 × 256 pixels. The total size of the blocks is 4352 (H)× 3072 (V), but the actual number of
effective pixels for the camera is 4112 (H) ×3008 (V) .The ineffective peripheral areas will be
deleted internally on the camera automatically.
SP-12401C-USB
For a full image, the number of correction blocks is 16 (H) × 12 (V) blocks.
The total size of the blocks is 4096 (H) × 3072 (V).
The actual number of effective pixels for the camera is 4088 (H) x 3000 (V).
When using ROI, the number of blocks and the number of pixels that comprise each block
differ from a full image.
