Abstract:
1. An image processing system for calculation of the color values from raw image data with a mosaic color element array pattern, said image processing system comprising: a shift invariant point determining device for ascertaining shift invariant points within said mosaic color element array pattern; an illumination averager in communication with said shift invariant point determining device to receive said shift invariant points within said mosaic color element array pattern and then receives said raw image data to determine average illumination values of clusters of a plurality of color elements of said mosaic color element array pattern at said shift invariant points; a second order differentiator in communication with said shift invariant point determining device to receive said shift invariant points and with said illumination averager to receive the average illumination values for said clusters of said plurality of color elements at said shift invariant points to determine a second order derivative of said average illumination values of said clusters of said plurality of color elements at said shift invariant points; and a color data calculator that receives said image data and in communication with said second order differentiator to receive said second order derivative and from said image data and second order derivative determines color data for each of shift invariant points.
