Classification: CPC H | IPC H

Claim 1:
2. An encoding method, comprising:
selecting an encoding mode from among candidates including a decoder-side motion vector refinement (DMVR) encoding mode and a partition encoding mode,
when the DMVR encoding mode is selected:
obtaining a first motion vector for a first image block;
deriving a second motion vector from the first motion vector using motion search; and
generating a prediction image for the first image block using the second motion vector; and

when the partition encoding mode is selected:
determining a plurality of partitions in a second image block;
obtaining a third motion vector for each partition;
generating a prediction image for the second image block using the third motion vector, without deriving a fourth motion vector from the third motion vector using motion search; and
storing, into a bitstream, a flag indicating the partition encoding mode.
