Abstract:
An image processing device and method that enable suppression of a reduction in coding efficiency. The image processing device dequantizes quantized data generated through decoding, using a default quantization matrix having a same size as a block size that is a unit of processing in which dequantization is performed, when in a copy mode in which a quantization matrix is copied, quantization matrix reference data identifying a reference destination of the quantization matrix matches quantization matrix identification data identifying the quantization matrix. The device and method can be applied to an image processing device.

Claim (Index 12):
An image processing method comprising:\n decoding encoded data that includes a replacement difference coefficient which is a difference between a replacement coefficient used to replace a (0, 0) coefficient of a 32\u00d732 quantization matrix and a (0, 0) coefficient of an 8\u00d78 quantization matrix, to generate quantized data; setting a 32\u00d732 default quantization matrix as the current quantization matrix, when a current quantization matrix is copied and as a condition that a difference value between a value of identification information identifying a reference quantization matrix and a value of identification information identifying the current quantization matrix is equal to 0; setting the 32\u00d732 quantization matrix as the current quantization matrix by using a nearest neighboring interpolation process against the 8\u00d78 quantization matrix including the sum of the replacement difference coefficient and the replacement coefficient as the (0, 0) coefficient of the 8\u00d78 quantization matrix and by replacing the (0, 0) coefficient with the replacement coefficient, when the current quantization matrix is not copied; and dequantizing the quantized data generated in the decoding, using the current quantization matrix, thereby improving coding efficiency.
