Claim:
1. A method comprising: providing a multi-layer image sensor having a plurality of pixels arranged in a pixel array and further having at least one layer of Color Filer Array (CFA) overlaid on the pixel array such that at least one location-specific color filter is associated with each pixel location in the pixel array; collecting one or more color signals from each pixel location in the pixel array during a single imaging operation, wherein each color signal associated with a given pixel location represents a different color of light; for each pixel location, selectively combining only those color signals which are collected from the pixel location so as to obtain a pixel location-specific color content that is independent of color signals collected from neighboring pixel locations in the pixel array; and using each pixel location-specific color content to construct the following two color patterns, each color pattern having colors arranged in one-to-one correspondence with each pixel location in the pixel array:
