Abstract: An image encoding and decoding method comprises the steps of: determining an inter-component prediction mode of a chrominance component block on the basis of an inter-component prediction mode list and predetermined index information; determining a reference sample for inter-component prediction of the chrominance component block on the basis of the determined inter-component prediction mode; deriving the parameters of a linear prediction model by using the reference sample; and performing inter-component prediction for the chrominance component block by using the parameters of the linear prediction model.

Abstract: An encoding/decoding method and device according to the present disclosure may: determine at least one among a plurality of inter prediction modes as the inter prediction mode of the current block; form an inter prediction candidate list on the basis of the determined inter prediction mode; perform motion compensation on the basis of one prediction candidate in the inter prediction candidate list, and generate a first prediction block of the current block; and correct the first prediction block by using a prescribed intra prediction mode.
