Encoding methods, decoding methods, and methods for sending bit streams

Abstract

In inter-prediction mode, the encoding device generates a first predicted image of the target block based on the derived motion vector, and applies an update process to the first predicted image to generate the final predicted image of the target block. Here, the update process candidates include a first process and a second process; the first process is a BDOF process, and the second process is a process that mixes the second predicted image generated by the intra-prediction of the target block with the first predicted image. Then, in the application of the update process, the first process and the second process are applied exclusively.
