Abstract
An image decoding method may comprise determining a prediction mode of a current block as an affine intra prediction mode, determining a control point block vector of the current block, determining block vectors of sub-blocks of the current block based on the control point block vector of the current bloc, and predicting the current block using reference blocks of a current picture indicated by the block vectors of the sub-blocks.
