Image encoding/decoding methods and apparatuses and image processing equipment

Abstract

Embodiments of this disclosure provide an image encoding/decoding methods and apparatuses and an image processing equipment. The image encoding method includes: determining a search sub-region of a current encoding unit from a plurality of sub-regions of a search region according to one or more motion vectors of one or more encoded units; obtaining one or more motion vectors of the current encoding unit based on the search sub-region; calculating residual information on the current encoding unit according to the motion vectors; and encoding the residual information on the current encoding unit into a bit stream. Hence, the search region may be reduced, and the number of search points may be lowered, thereby shortening PMMVD encoding/decoding time.
