Abstract
An image encoding/decoding method is disclosed. An image decoding method of the present invention may comprise deriving an intra-prediction mode of a current block by using an intra-prediction mode of a neighbor block adjacent to the current block, configuring a reference sample of the current block, and performing intra-prediction on the current block by using the intra-prediction mode and the reference sample, wherein when the intra-prediction mode of the neighbor block is unavailable, the intra-prediction mode of the neighbor block may be replaced with a planar mode.
