CPC Class H04N

A video image processing method includes dividing a current image block into a plurality of sub-blocks, in response to a target neighboring block of the current image block satisfying a preset condition, determining related blocks of the sub-blocks in a collocated frame of the current image block according to a motion vector of the target neighboring block, encoding or decoding the current image block according to motion vectors of the related blocks of the sub-blocks, determining a group of control point motion vectors in an affine transformation mode using one or more neighboring blocks of the current image block, and adding the group of control point motion vectors to a motion vector candidate list of the current image block.
