Paper Abstract

This paper describes a hybrid technique of coupling a through-the-lens band-pass illumination sensor with a software segmentation and histogram algorithm to estimate the scene illuminant(s) in a digital still camera and color correct the resulting image. A fuzzy logic algorithm combines the result of the source illumination(s) with the chromaticity determination of near-neutral objects derived from the image pixel data to determine the amount chromatic correction required.
