ABSTRACT:
Apparatus is disclosed for processing a digitized image obtained from an image sensor having color photosites aligned in rows and columns that generate at least four separate color values but only one color value for each photosite location, adjacent rows of values for each photosite being combined so that for each pair of photosites there is a single color value which is a combination of at least two different color values. In this apparatus, the combined single color values are used to produce Laplacian values for each pair of photosites. Also, the color signal values corresponding to adjacent pairs of photosites and the Laplacian values are used to produce a luminance value corresponding to each pair of photosites. Thereafter, color signal values corresponding to adjacent pairs of photosites and the Laplacian values are used to produce a chrominance value corresponding to each pair of photosites, and the luminance and chrominance values corresponding to each pair of photosites are used to produce a full color digitized image.
