LIGHT COMPENSATION METHODS, ENCODERS, DECODERS, AND METHODS FOR BIT STREAM TRANSMISSION

Abstract

The illumination compensation method refers to the encoder, decoder, and method for transmitting the bit stream. The bit stream is received and parsed to receive the illumination compensation enable flag, current movement information, and current forecast mode. The enable flag allows the illumination compensation frame level in the received bit stream when the enable flag is valid. The enable flag uses illumination compensation in the received bit stream when the enable flag is valid. The index information of the target illumination compensation mode is in the received bit stream when the enable flag is valid. Illumination compensation is performed on the current block based on the index information of the target illumination compensation mode.
