Abstract

A method, apparatus and system for performing a demosaic operation are described. In one embodiment, the apparatus comprises: a plurality of interpolation modules to perform a plurality of interpolation operations to generate color pixel values of a first color for a plurality of pixel locations in an image region that do not have color pixel values of the first color; a first module to generate a set of color pixel values of the first color for the image region, one or more color pixel values in the set of pixel values being generated based on color pixel values of the first color from one of the plurality of interpolation modules; and a second module to select the one interpolation module based on an interpolation direction determined by color intensity gradient calculations that involve pixel values of the first color and at least one other color.
