Claim 6:
7. The image decoding method of claim 3, wherein the DMVR flag information related to applying the DMVR to the current block is derived based on at least one of a case where an inter bi-prediction based on the DMVR is enabled, a case where the bi-prediction being performed based on the L0 reference picture and the L1 reference picture is applied to the current block, a case where a difference from the L0 reference picture and a difference from the L1 reference picture are equal to each other based on a current picture, a case where a merge mode is applied to the current block, a case where a merge mode with motion vector difference (MMVD) mode is not applied to the current block, a case where a height of the current block is equal to or larger than 8, or a case where the height×width of the current block is larger than 8×8.
