| 摘要 |
The present technology relates to an image processing device and method that enable an increase in encoding efficiency with respect to quantization parameters. The present invention is provided with: a predicted quantization parameter setting unit that sets predicted quantization parameters with respect to a current coding unit using a plurality of quantization parameters set in a plurality of peripheral coding units that are positioned in the periphery of the current coding unit that is the subject of encoding processing; and a differential quantization parameter setting unit that sets differential quantization parameters indicating the differential value between the quantization parameters set in the current coding unit and the predicted quantization parameters set by the predicted quantization parameter setting unit. The present disclosures, for example, can be applied to an image processing device. |
