Classification: CPC H | IPC H

Claim 7:
8. A image method performed by an encoding apparatus, the image method comprising:
determining that a merge with motion vector difference (MMVD) mode is applied to a current block which is a current picture referencing (CPR) coding block referring to a current picture;
determining whether a reference picture list for the current block includes only the current picture or includes one or more reference pictures other than the current picture;
deriving a base motion information candidate based on motion information of a neighboring candidate block which is the CPR coding block among neighboring candidate blocks;
generating prediction samples for the current block based on the base motion information candidate;
deriving residual samples based on the prediction samples; and
encoding image information including information on the residual samples,
wherein the base motion information candidate is derived based on the motion information of the neighboring candidate block which is the CPR coding block when the reference picture list includes only the current picture.
