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 controlling a chromatic signal based on a block matching result through receiving an RGB signal and a luminance/chromaticity signal. CONSTITUTION: A YUV converter(120) converts an RGB signal into a YUV signal. A block matching unit(130) proceeds block matching with an inputted G signal and B signal of an area dividing unit(110) according to an area. Based on a matching result, the block matching unit controls an inputted U signal of the YUV converter. An RGB converter(140) proceeds RGB signal conversion through a YUV signal and a controlled U0 signal of the YUV converter.
