Disclosed herein is a method of decoding an image. The method includes determining a prediction mode of a current block as a merge mode with motion vector difference (MMVD), deriving a merge candidate list of the current block, deriving a motion vector predictor of the current block using the merge candidate list, deriving a motion vector difference of the current block, and deriving a motion vector of the current block using the motion vector predictor and the motion vector difference. Only some of candidates in the merge candidate list are used to derive the motion vector predictor.

Image encoding/decoding method and apparatus, and recording medium for storing bitstream

An image encoding/decoding method is disclosed. An image decoding method of the present invention may comprise identifying a region by partitioning an image, and determining a prediction mode of the region on the basis of at least one of a size of the region, a partition shape, and a coding parameter of the region. The determined prediction mode of the region may be determined as a prediction mode of all coding blocks included in the region.
