Classification: CPC H | IPC H

Claim 0:
1. An image motion compensation method comprising:
obtaining initial motion vectors (MVs) of a current image block, the initial MVs including a first initial MV and a second initial MV; and
performing:
in response to determining that at least one of a reference image pointed to by the first initial MV or a reference image pointed to by the second initial MV is a long-term reference image:
skipping scaling of the first initial MV and the second initial MV; and
performing motion compensation on the current image block based on the first initial MV and the second initial MV; and/or

in response to determining that the reference image pointed to by the first initial MV and the reference image pointed to by the second initial MV are short-term reference images:
determining a scaling factor of the first initial MV and a scaling factor of the second initial MV;
scaling the first initial MV based on the scaling factor of the first initial MV;
scaling the second initial MV based on the scaling factor of the second initial MV; and
performing motion compensation on the current image block based on the first initial MV after being scaled and the second initial MV after being scaled.
