IMAGE DECODING EQUIPMENT AND IMAGE DECODING METHODS

Abstract

The proposed image decoder uses a selective flag to mask the fusion mode in the absence of MMVD mode, thus achieving high encoding performance. The image decoder includes a parameter decoder, and in the case where the normal fusion flag indicates the normal fusion mode, it checks whether the predicted MMVD flag signaled in the sequence parameter set or similar set is available, and if the predicted MMVD is not available, it decodes the motion vector information obtained from the fusion candidate.
