Most digital use a single sensor and capture color information using a color filter array (CFA). Interpolation of the color samples obtained through a CFA is a very critical task in a digital camera pipeline. We have developed algorithms that exploit inter-channel and intra-channel correlations to perform color interpolation accurately.
