Abstract
The invention discloses an image decoding method and an image encoding method. The image decoding method includes decoding the information about a quantization matrix; reconstructing a quantization matrix based on the information about the quantization matrix; generating a residual block for the current block based on the quantization matrix; and reconstructing the current block based on the residual block and the prediction block for the current block. The information on the quantization matrix includes the information indicating a prediction method of the quantization matrix. The informationon the quantization matrix further includes at least one of the information indicating a prediction method of the quantization matrix, the information on a reference quantization matrix identifier ofthe quantization matrix, the information indicating a DC value of the quantization matrix, and the information indicating a difference between the quantization matrix coefficients. The step of reconstructing the quantization matrix based on the information about the quantization matrix includes deriving the quantization matrix coefficient; arranging the quantization matrix coefficients in the quantization matrix by performing the right upper diagonal scanning on the quantization matrix coefficients.
