  • Digital still camera system and complementary-color-filtered array interpolation method
    Patent number: 7330209
    Abstract: A complementary-color-filtered array interpolation by first interpolate each color subarray so each pixel has four colors and then adjust each color at a pixel with addition or subtraction of a color imbalance factor for the pixel. For yellow and cyan the adjustment is subtraction but for magenta and green the adjustment is addition.
