Abstract
Disclosed are a method and an apparatus for intra prediction mode encoding that may increase compression efficiency of intra prediction mode encoding. The intra prediction mode encoding method may include detecting a similarity of a prediction direction of a neighbor block with respect to a current block based on a position of the neighbor block and an intra prediction direction of the neighbor block with respect to the current block, and determining a candidate prediction mode of the current block based on the similarity and the number of candidate intra prediction modes (N). Accordingly, intra encoding performance of an image may be improved by more accurately and efficiently compressing information about an intra prediction mode of a current block by considering local statistics, which is different from a related art in which only global statistics are considered.
