Abstract
An image decoding method according to the present disclosure may comprise obtaining a first prediction block for the current block; obtaining a second prediction block for the current block; and obtaining a final prediction block for the current block on the basis of a weighted sum operation of the first prediction block and the second prediction block. In this instance, the first prediction block is obtained by performing motion compensation on each of first sub-blocks generated when a first partition type is applied to the current block, and the second prediction block is obtained by performing motion compensation on each of second sub-blocks generated when a second partition type is applied to the current block.
