    Abstract: An image decoding method includes: configuring a MPM list including candidate intra prediction modes for a current block; deriving an intra prediction mode of the current block from the MPM list on the basis of MPM index information indicating an intra prediction mode, among the candidate intra prediction modes included in the MPM list, for the current block; generating prediction samples for the current block on the basis of the intra prediction mode; and generating a reconstructed picture for the current block on the basis of the prediction samples, wherein the step for configuring the MPM list comprises, on the basis of the case where the value of reference line index information, representing a reference line used for the intra prediction of the current block, is not zero, deriving a DC mode as one mode among the candidate intra prediction modes, and including same in the MPM list.

    Abstract: A picture decoding method which is performed by a decoding apparatus according to an example of the present disclosure includes constructing a Most Probable Modes (MPM) list including intra prediction mode candidates for a current block based on neighboring blocks of the current block, decoding remaining mode information indicating one of remaining intra prediction modes other than the intra prediction mode candidates included in the MPM list from a bitstream, determining an intra prediction mode of the current block based on the decoded remaining mode information, generating prediction samples for the current block based on the determined intra prediction mode, and generating reconstructed samples for the current block based on the prediction samples for the current block, wherein the remaining mode information is decoded based on a truncated binary code.
