Shading Correction

The shading correction is a function that 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).
The size of the correction block is 20 (H) × 17 (V) blocks and calculation errors in the correction data
are minimized due to the small interpolation block. Each block is 128 × 128 pixels.
The total size of the blocks is 2560 (H) × 2176 (V), but the actual number of effective pixels for the
camera is 2464 (H) × 2056 (V). The ineffective peripheral areas will be deleted internally on the camera
automatically.

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.
