ABSTRACT:
A color filter array for use with an electronic image sensor is disclosed, wherein the red and blue filter elements of the color filter array are arranged to correspond with an interleaved chrominance channel pattern. Thus, actual red and blue values are utilized to generate interleaved chrominance channel information instead of interpolated values as required by conventional CFA patterns.
