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 2):
An image processing device, comprising:\n a decoding unit configured to decode a bit stream including a second quantization matrix of second size extracted from elements of a first quantization matrix of first size as to generate quantized data; a setting unit configured to set the first quantization matrix of first size by performing a nearest neighbor interpolation process onto each element of the second quantization matrix of the second size during performing an inverse orthogonal transform, in transformation units of the first size, onto transform coefficient data dequantized from the quantized data generated by the decoding unit; and a dequantization unit configured to dequantize the quantized data generated by the decoding unit using the first quantization matrix of first size set by the setting unit.
