Abstract

A method of processing image data produced by a solid state image sensor that is overlaid with a color filter array is based on range scaling, demosaicing, matrixing, range clipping and gamma correction being performed in two data collection passes. The demosaicing can be performed with pixels grouped in 2×2 blocks, or quads.
