METHOD AND APPARATUS FOR COMPENSATING ILLUMINATION COMPENSATION AND METHOD AND APPARATUS FOR ENCODING MOVING PICTURE BASED ON ILLUMINATION COMPENSATION, AND METHOD AND APPARATUS FOR ENCODING MOVING PICTURE BASED ON ILLUMINATION COMPENSATION

摘要

An illumination compensation method, an apparatus therefor, a moving picture encoding method using the same, and an apparatus therefor are provided to increase coding efficiency because a parameter for illumination compensation is not transmitted. An illumination compensation parameter calculating unit(120) calculates an illumination compensation parameter of a reference block on the basis of correlation between pixel values of recovered peripheral pixels of a current block to be encoded in a current frame and pixel values of recovered peripheral pixels of the reference block. An illumination-compensated reference block generating unit(140) generates an illumination-compensated reference block on the basis of the calculated illumination compensation parameter.
