Abstract
Disclosed herein are a decoding method and apparatus and an encoding method and apparatus for deriving an intra prediction mode. An intra prediction mode may be derived using a method for deriving an intra prediction mode based on a neighbor block of the target block, a method for deriving an intra prediction mode using signaling of the intra prediction mode of the target block, or a method for deriving an adaptive intra prediction mode based on the type of a target slice. An MPM list may be used to derive the intra prediction mode, and a temporal neighbor block or the like may be used to configure the MPM list.
