Abstract
A method for correcting a color video signal for white balance comprising the steps of: providing a digital color image signal having a sequence of monocolor pixels, wherein each of the pixels represents one color of first, second, and third different colors, which are repeated in a preset pattern; coarse white balance processing each monocolor pixel for a coarse white balance; spatial processing the sequence of monocolor pixels to produce a sequence of tricolor pixels, wherein each of the tricolor pixels represents the first, second, and third different colors; and color correction and fine white balance processing each of the tricolor pixels by means of a matrix multiplier for color correction and fine white balance.
