Abstract
An image encoding/decoding method and apparatus are provided. An image decoding method according to the present disclosure may include parsing, from a bitstream, first information specifying whether block difference pulse code modulation (BDPCM) applies to an intra-predicted current block, determining a prediction direction of BDPCM for the current block and generating a residual block of the current block based on the determined prediction direction of BDPCM, based on the first information specifying that BDPCM applies to the current block, generating a prediction block of the current block, by performing intra prediction based on an intra prediction mode of the current block, and reconstructing the current block based on the residual block and the prediction block.
