摘要： An image encoding/decoding method and apparatus are provided. An image encoding method performed by an image encoding apparatus may comprise determining an intra-prediction mode of a current block, configuring a reference sample of intra prediction by using at least one of a neighbor pixel of the current block in a current picture and a pixel of a reference picture, and performing intra prediction for the current block based on the intra-prediction mode and the reference sample.
