Abstract
An image motion compensation method includes obtaining a first initial MV and a second initial MV of a current image block. The method further includes: if at least one of reference images pointed to by the first and second initial MVs is a long-term reference image, skipping scaling of the first and second initial MVs and performing motion compensation on the current image block based on the first and second initial MVs; and/or, if both the reference images pointed to by the first and second initial MVs are short-term reference images, determining scaling factors of the first and second initial MVs, scaling the first and second initial MVs based on the scaling factors, and performing motion compensation on the current image block based on the first and second initial MVs after being scaled.
