- Abstract
- An image encoding/decoding method and apparatus are provided. An image decoding method of the present invention comprises decoding first information indicating whether a maximum of N intra prediction modes are used or a maximum of M intra prediction modes are used for an intra prediction for a current block, in which the M is smaller than the N, deriving an intra prediction mode of the current block, inverse-mapping the derived intra prediction mode on a corresponding intra prediction mode among the maximum N intra prediction modes when the decoded first information indicates that the maximum M intra prediction modes are used for the intra prediction for the current block, and generating an intra prediction block by performing an intra prediction for the current block, based on the inverse-mapped intra prediction mode.
