Abstract:
The present disclosure relates to an image processing device and method that enable suppression of an increase in the amount of coding of a quantization matrix. An image processing device of the present disclosure includes an up-conversion unit configured to up-convert a quantization matrix limited to a size less than or equal to a transmission size that is a maximum size allowed for transmission, from the transmission size to a size that is identical to a block size that is a processing unit of quantization or dequantization. The present disclosure is applicable to, for example, an image processing device for processing image data.

Claim (Index 8):
An image processing device, comprising:\n a setting unit configured to set a second quantization matrix of second size corresponding to a transform unit of second size by performing a nearest neighbor interpolation process onto each element of a first quantization matrix of first size; a quantization unit configured to quantize transform coefficient data generated by orthogonal transforming image data in transformation units of second size by using the second quantization matrix of second size set by the setting unit as to generate quantized data; and an encoding unit configured to encode the quantized data generated by said quantization unit to generate a bit stream including the first quantization matrix of first size resulted from thinning out the repeated elements from each element of the second quantization matrix of second size set by said setting unit.
