EL-2800M-CXP / EL-2800C-CXP

- 58 -

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.

Fig. 47 Flat shading correction concept drawing

Color shading correction (For EL-2800C only):

In this case, R channel and B channel are adjusted to match with G channel characteristics.
The block grid for compensation is 15(H) x 12(V) blocks and the complementary process is
applied to produce the compensation data with less error.

Before adjustment After adjustment

Fig.48 Color shading correction concept drawing

Note: Under the following conditions, the shading correction circuit may not work properly.



If there is some area in the image with a video level less than 70%



If part of the image or the entire image is saturated



If the highest video level in the image is less than 300LSB (at 10-bit output)

Adjustable range

Less 30%
