An image decoding method performed by an image decoding apparatus may include identifying a prediction mode of a current block, 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 being an intra prediction mode, generating a candidate intra prediction mode list of the current block based on the candidate intra prediction mode, and determine an intra prediction mode of the current block based on the candidate intra prediction mode list. In this case, the candidate intra prediction mode may be determined to be a predetermined intra prediction mode, based on the prediction mode of the neighboring block being an MIP mode.
