Abstract
An illumination compensation method, an encoder, and a decoder are provided in implementations of the disclosure. A bitstream is obtained, and the bitstream is parsed to obtain an illumination compensation enabled flag. An illumination compensation frame-level enabled flag in the bitstream is obtained, when the illumination compensation enabled flag is valid. An illumination compensation usage flag in the bitstream is obtained, when the illumination compensation frame-level enabled flag is valid. Index information of a target illumination compensation mode in the bitstream is obtained, when the illumination compensation usage flag is valid. Illumination compensation is performed on a current block based on the index information of the target illumination compensation mode.
