METHOD AND DEVICE FOR ENCODING/DECODING IMAGE

摘要

A method and a device for encoding/decoding an image are disclosed. The method for decoding an image comprises the steps of: decoding information on a quantization matrix; and restoring the quantization matrix on the basis of the information on the quantization matrix, wherein the information on the quantization matrix includes information indicating a DC value of the quantization matrix and/or information indicating differential values of quantization matrix coefficients.
