Abstract
An electronic image capture device for capturing a color image, comprising an image sensor comprised of discrete light sensitive picture elements overlaid with a color filter array (CFA) pattern to produce sensor color image data corresponding to the CFA pattern; an A/D converter for producing uninterpolated digital CFA image data from the sensor color image data; a processor for processing the uninterpolated digital CFA image data to produce interpolated image data and for forming a TIFF image file containing both the uninterpolated CFA image data and the interpolated image data; and a memory for storing the TIFF image file.
