INTER PREDICTION METHOD AND APPARATUS USING CPR-BASED MMVD

WIPO Patent Application WO/2020/141932

A1

An image decoding method performed by a decoding apparatus according to the present document comprises the steps of: determining that a merge with motion vector difference (MMVD) mode has been applied to a current block that is a current picture referencing (CPR) coding block referring to a current picture; deriving a base motion information candidate for the current block on the basis of candidate blocks neighboring the current block ; generating prediction samples for the current block on the basis of the base motion information candidate; and generating reconstruction samples for the current block on the basis of the prediction samples, wherein the base motion information candidate is derived depending on whether the neighboring candidate blocks are CPR coding blocks.
