Abstract
Missing intensity values for color values for a color component array derived from a color filter array are predicted using the system and method of the present invention. The method uses predictor sets for each missing intensity value to select a best value for each missing intensity value. The predictor sets include a luminance predictor set, a first chrominance predictor set and a second chrominance predictor set. The member predictors of the luminance predictor set are selected in response to a comparison between a variance between neighboring luminance values and a predetermined threshold. The first chrominance set is used to predict chrominance values of a color type at locations where a chrominance value of another color type was originally stored. The second chrominance set is used to predict chrominance values of a color type at locations where a luminance value was originally stored. Preferably, the member elements of the predictor sets are ranked and the median values selected as the missing intensity value.
