Abstract

A method for decoding an image according to a decoding device of the document comprises the following steps: acquiring image information; and generating a reconstructed picture based on the image information.

Description

technical field [0001] This document relates to image coding technology, and more specifically, to an image decoding method for coding CU-level chroma quantization parameter offset-related information in an image coding system, and an apparatus for the image decoding method. 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 hi...
