METHOD AND DEVICE FOR ENCODING/DECODING IMAGE, AND RECORDING MEDIUM STORING BIT STREAM

Abstract: an image decoding/encoding method and apparatus are discussed. the image decoding method can include deriving an intra prediction mode of a current chroma block, wherein an inter-color component intra prediction is applied to the current chroma block, deriving luma reference samples of a luma block related to the current chroma block, deriving downsampled luma reference samples based on the luma reference samples, and deriving chroma reference samples for the current chroma block.
