Abstract:
An image processing device and method that enable suppression of an increase in the amount of coding of a scaling list. The image processing device sets a coefficient located at the beginning of a quantization matrix by adding a replacement difference coefficient that is a difference between a replacement coefficient used to replace a coefficient located at the beginning of the quantization matrix and the coefficient located at the beginning of the quantization matrix to the coefficient located at the beginning of the quantization matrix; up-converts the set quantization matrix; and dequantizes quantized data using an up-converted quantization matrix in which a coefficient located at the beginning of the up-converted quantization matrix has been replaced with the replacement coefficient. The device and method can be applied to an image processing device.

Claim (Index 10):
An image processing method, comprising:\n setting, using circuitry, a replacement coefficient which is used to replace a (0, 0) coefficient of a first quantization matrix according to a replacement difference coefficient that is a difference between the replacement coefficient and a (0, 0) coefficient of a second quantization matrix and the (0, 0) coefficient of the second quantization matrix according to the replacement difference coefficient; replacing the (0, 0) coefficient of the first quantization matrix set by the circuitry with the replacement coefficient; and dequantizing quantized data obtained by decoding encoded data, using the first quantization matrix in which the (0, 0) coefficient of the first quantization matrix has been replaced with the replacement coefficient by the circuitry.
