Claim One:
1. A method for correcting colored fringe artifacts in a region of a color digital image comprised of a two-dimensional array of image pixels, the colored fringe artifacts occurring round saturated image pixels captured by an electronic imager associated with a color filter array, comprising a processor for performing the following steps: (a) providing a threshold map of the image based on thresholding one or more color channels of the color digital image with a common or separate threshold value for each color channel; (b) providing a first edge map representing colored fringe pixels having colored fringe artifacts by dilating the threshold map as a function of the width of the colored fringe artifact, producing a first dilated threshold map and subtracting the threshold map from the first dilated threshold map; and (c) color-desaturating the colored fringe image pixels that correspond to the first edge map to provide a corrected color digital image having reduced colored fringe artifacts.
