Abstract
A method of modifying a CFA image or full-color image having a plurality of color channels and a panchromatic channel, includes capturing the panchromatic channel at a different exposure time than at least one of the color image channels with the CFA sensor within one image; producing a panchromatic edge map and a color edge map from the CFA image; using the panchromatic edge map and the color edge map to provide motion estimates; and using the motion estimates to modify at least one of the channels of the CFA image or full-color image.
