ENCODER, DECODER, ENCODING METHOD, AND DECODING METHOD

Abstract: an encoder includes circuitry and memory connected to the circuitry. in operation, the circuitry: stores mv information and correction processing information into a fifo buffer for an hmvp mode in association, the mv information being derived for a processed block and correction processing information being related to correction processing of a prediction image of the processed block; registers, in a prediction candidate list for a merge mode, one or more prediction candidates each being a combination of mv information and correction processing information, the prediction candidates including a prediction candidate which is a combination of the motion vector information and the correction processing information stored in the fifo buffer; and selects a prediction candidate from the prediction candidate list when a current block is to be processed in the merge mode, and performs correction processing of a prediction image of the current block, based on the correction processing information.
