Shading Correction
This function compensates for shading (non-uniformity) caused by the lens or the light source used.
This compensation can be performed even if shading issues are not symmetrical in horizontal and/or
vertical directions.
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 grid for compensation is 15
(H) x 12(V) blocks with 128 pixels x 128 pixels for each block .The complementary process
is applied to produce the compensation data with less error.
