METHOD AND APPARATUS FOR CANCELING AN CHROMATIC ABERRATION

摘要

PURPOSE: A chromatic aberration removal method and a device thereof are provided to remove chromatic aberration regardless of lens characteristic by filtering only a chromatic signal in a luminance/chrominance coordinate system through an asymmetry mask according to property of chromatic aberration generation. CONSTITUTION: A YUV converter(110) converts an RGB signal into a YUV signal. In order to create a chromatic signal for chromatic aberration compensation, a chromatic signal generator(130) filters the chromatic signal through an asymmetry mask according to an area. A chromatic signal combiner(150) combines information about chromatic aberration generation, the chromatic signal for the chromatic aberration compensation and an input chromatic signal. An RGB converter(160) proceeds signal conversion through a final chromatic signal and a brightness signal of the YUV converter.
