Abstract
An image encoding/decoding method and device according to the present disclosure may configure a reference sample for a cross component prediction of a chroma component block, derive a cross component prediction parameter by using the reference sample, and make a cross component prediction of the chroma component block on the basis of the cross component prediction parameter and a luma component block corresponding to the chroma component block.
Claims9
A method of decoding an image, comprising:
- constructing a reference sample for cross component prediction of a chroma component block;
- deriving a cross component prediction parameter using the reference sample;
- and
- performing the cross component prediction of the chroma component block based on a luma component block corresponding to the chroma component block and the cross component prediction parameter.
