Abstract
A method for decoding a current block of a picture is disclosed. First, at least one illumination compensation parameter for the current block is decoded responsive to a comparison of a parameter of the current block with a value. Then, an accessed motion compensation reference block is compensated in illumination responsive to the at least one illumination compensation parameter. Finally, the current block is reconstructed from the illumination and motion compensated reference block.
