Abstract
An image encoding/decoding method and apparatus include features of generating a prediction block by performing intra prediction on a current block, determining whether to apply position dependent intra prediction combination (PDPC) to the prediction block, and generating a final prediction block of the current block, by applying PDPC to the prediction block based on the determination. The determining whether to apply PDPC to the prediction block may include determining whether a size of the current block satisfies a predetermined condition. Based on the size of the current block satisfying the predetermined condition, it may be determined to apply PDPC to the prediction block. Based on the size of the current block not satisfying the predetermined condition, a determination of a color component of the current block may be skipped and it may be determined not to apply PDPC to the prediction block.
