Abstract

An image decoding method performed by a decoding device according to this document comprises the steps of: determining whether the width and the height of a current block are smaller than or equal to the size of a maximum transform block; when the width and the height are smaller than or equal to the size of the maximum transform block, obtaining a BDPCM flag representing whether or not to apply BDPCM for the current block; deriving prediction samples for first and second samples of the current block on the basis of the BDPCM flag; deriving residual samples on the basis of received residual information; and deriving reconstructed samples for the first and second samples on the basis of the prediction samples and the residual samples.

Description

technical field [0001] The present disclosure relates to image coding technology, and more particularly, to an image decoding method and device for executing BDPCM in an image coding system to code a current block. Background technique [0002] Recently, in various fields, demands for high-resolution, high-quality images such as HD (High Definition) images and UHD (Ultra High Definition) images are increasing. Because image data has high resolution and high quality, the amount of information or bits to be transmitted increases relative to conventional image data. Therefore, when image data is transmitted using a medium such as a conventional wired / wireless broadband line or stored using an existing storage medium, its transmission cost and storage cost increase. [0003] Therefore, a high-efficiency image compression technique for efficiently transmitting, storing, and reproducing information of high-resolution high-quality images is required.
