　The present disclosure pertains to an image processing device and method that enable the inhibition of an increase in the amount of coding for a scaling list. This image processing device sets the coefficient positioned at the head of a quantization matrix by adding, to the coefficient positioned at the head of the quantization matrix, a replacement difference coefficient which is the difference between the coefficient positioned at the head of the quantization matrix, and the replacement coefficient to be used when replacing the coefficient positioned at the head of the quantization matrix. The quantization matrix which has been set is upconverted, and an upconverted quantization matrix in which the coefficient positioned at the head of the upconverted quantization matrix has been replaced by the replacement coefficient is used for the inverse quantization of the quantized data. The present disclosure can be applied to image processing devices. |
