Patent
An image encoding/decoding method and apparatus are provided. An image decoding method performed by an image decoding apparatus includes determining an MPM (most probable mode) candidate of a current block based on a prediction mode of a neighboring block located around the current block, generating an MPM list of the current block based on the MPM candidate, and determining an MPM candidate identified by an intra prediction mode indicator among a plurality of MPM candidates included in the MPM list to be a prediction mode of the current block. The MPM candidate determined based on the prediction mode of the neighboring block may be determined to be a predetermined intra prediction mode, based on the prediction mode of any one of the current block and the neighboring block being a matrix based intra prediction mode.
