Claim 0:
1. An image decoding method performed by an image decoding apparatus, the image decoding method comprising:
identifying a prediction mode of a current block;
identifying whether an intra prediction mode of the current block is an MIP (matrix-based intra prediction) mode, based on the prediction mode of the current block being the intra prediction mode;
determining a candidate intra prediction mode for the current block based on a prediction mode of a neighboring block located around the current block, based on the intra prediction mode of the current block not being the MIP mode;
generating a candidate intra prediction mode list of the current block based on the candidate intra prediction mode; and
determining the intra prediction mode of the current block based on the candidate intra prediction mode list,
wherein the candidate intra prediction mode is determined to be a predetermined intra prediction mode, based on the prediction mode of the neighboring block being an MIP mode,
wherein the candidate intra prediction mode is determined to be the predetermined intra prediction mode, based on the neighboring block not being available.
