storage requirement).
Digital gain and white balance (color separate gain for white balance).

•
Programmable CFA interpolation that operates on a 5x5 grid.
Conventional Bayer pattern RGB and complementary color sensors.
Support for an image that is downsampled by 2x in the horizontal direction (with and without phase
correction). In this case, the image is 2/3 populated instead of the conventional 1/3 colors.
•
Support for an image that is downsampled by 2x in both the horizontal and vertical direction. In this
case, the image is fully populated instead of the conventional 1/3 colors.

Programmable RGB-to-RGB blending matrix (9 coefficients for the 3x3 matrix).
Fully programmable gamma correction (1024 entries for each color held in an on-chip RAM).
Programmable color conversion (RGB to YUV) coefficients (9 coefficients for the 3x3 matrix).
Luminance enhancement (non-linear) and chrominance suppression & offset.
