Abstract
An image decoding/encoding method and apparatus are discussed. An image decoding method can include deriving a sub-block based temporal merge candidate of a current block based on a collocated block in a collocated picture, generating a sub-block based merge candidate list based on the sub-block based temporal merge candidate of the current block, deriving a motion vector for each of a plurality of sub-blocks of the current block based on the sub-block based merge candidate list, and deriving prediction samples of the plurality of sub-blocks of the current block based on the motion vector for each of a plurality of sub-blocks.
