Abstract:
1. An image processing system for demosaicing an image represented by raw sensor values generated by pixels within an array of pixels having at least two color planes, each of said pixels within said array of pixels producing a respective one of said raw sensor values in one of the at least two color planes for said image, said image processing system comprising: a buffer for storing at least a group of said raw sensor values produced by said pixels within a region of said image, said region being less than said image; and a processor connected to receive said group of raw sensor values stored in said buffer, determine regression coefficients representing the linear relations between the color planes for said region using at least said group of raw sensor values and calculate missing color sensor values associated with said pixels in said region of said image using said regression coefficients, said processor configured to use correlation coefficients between different ones of the color planes in said region to determine said regression coefficients.
