    Abstract: An intra prediction method according to the present invention comprises the steps of: acquiring information on a luma prediction mode of a current block and information on a chroma prediction mode of the current block from a bit stream; deriving a luma intra prediction mode of the current block on the basis of the information on the luma prediction mode; determining a chroma intra prediction mode of the current block on the basis of information on the luma intra prediction mode and the information on the chroma prediction mode; and generating a chroma prediction sample of the current block on the basis of the chroma intra prediction mode. According to the present invention, it is possible to reflect the difference between the ratio of the width to the height of a luma component and the ratio of the width to the height of a chroma component, and thus to more accurately perform intra prediction in units of samples and improve intra prediction performance.
