摘要：
Provided are an illumination compensation method and apparatus and video encoding/decoding methods and apparatuses using the illumination compensation method. The illumination compensation method for a reference block used for motion estimation includes receiving pixel values of reconstructed neighboring pixels around a current block to be encoded and pixel values of reconstructed neighboring pixels around the reference block, and performing illumination compensation with respect to the reference block based on the input pixel values of reconstructed neighboring pixels around the current block and the input pixel values of reconstructed neighboring pixels around the reference block.
