Methods of reducing aberrations in a digital image

A method of reducing aberrations in a digital image comprises capturing input samples associated with a plurality of pixels arranged in a matrix, wherein each pixel is associated with a color defining the digital image; establishing vertical chrominance groups associated with columns of the matrix and horizontal chrominance groups associated with rows of the matrix; determining chrominance values for the chrominance groups; determining, for each chrominance group, a mean value and, a sum of absolute differences between the chrominance values and the mean value for the chrominance values of the chrominance group; calculating, by a signal processing device, a plurality of weights comprising vertical weights associated with the vertical chrominance groups and horizontal weights associated with the horizontal chrominance groups based upon the sums of absolute differences; and determining a missing color component for a predetermined pixel of the plurality of pixels using the plurality of weights.
