11.10. Shading Correction

This function compensates for shading caused by the lens or the light source used.
There are two methods of correction.
Flat shading correction:
The method to compensate the shading is to measure the highest luminance level in
the image and use that data as the reference. Luminance levels of other areas are
then adjusted so that the level of the entire area is equal. The block for
compensation is 128pixels(H) x 128 pixels(V) and the complementary process is
applied to produce the compensation data with less error.
