Claim 11:
12. The encoder of claim 11, wherein the processor is configured to, when the coding mode is the second affine motion mode, traverse the second candidate list to acquire MVPs of at least two control points corresponding to each second reference block in the second candidate list, calculate MVs of control points at corresponding positions of the coding block based on the MVPs of the at least two control points corresponding to each second reference block, and acquire a second coding parameter corresponding to the coding block from the MVs, the second coding parameter representing a group of coding parameters that are obtained in the second affine motion mode for the coding block and have a minimum coding prediction cost; and
the processor is configured to perform predictive coding on the coding block based on the second coding parameter corresponding to the coding block.
