Abstract: An image decoding method according to the present invention comprises the steps of: referring to a first flag for indicating whether intra block-based delta pulse code modulation (BDPCM) signaled through a sequence parameter set is permitted, so as to determine whether a second flag for indicating whether the intra BDPCM is applied to a current block is parsed; determining whether the intra BDPCM is applied to the current block on the basis of the second flag; determining an intra BDPCM mode of the current block when it is determined that the intra BDPCM is applied to the current block; and acquiring a residual sample of the current block on the basis of the intra BDPCM mode.
