Abstract
An image decoding method for decoding a current block by using intra prediction includes: decoding information related to a chroma intra prediction mode of the current block from a bitstream; determining the chroma intra prediction mode by using a basic intra prediction mode set and an alternative mode according to a first luminance intra prediction mode corresponding to the current block and the related information; generating a prediction block of the current block by using the chroma intra prediction mode; reconstructing a residual block of the current block from the bitstream; and reconstructing the current block by adding the prediction block and the residual block. The alternative mode is adaptively determined.
