摘要

The present disclosure provides control point motion vectors determined using motion vectors of neighboring blocks included in a block group of neighboring blocks representing each corner of a current block when inter prediction of a current block is performed in an affine merge mode. The affine motion vector of the current block is generated in the afine merge candidate list including the afine merge candidate based on the control point corresponding to, and control point motion vectors corresponding to the merge candidate selected from the afine merge candidate list are used. Determining and acquiring prediction samples of the current block using a motion vector that is an affine of the current block, and when a right block of the current block is available, a representative neighboring block adjacent to the lower right corner of the current block Is a block from which available motion information is obtained from among neighboring blocks adjacent to the lower right corner of the current block and the right outline of the current block, and neighboring blocks diagonally adjacent to the lower right corner of the current block. Provides a way.
