| 摘要 |
The present disclosure relates to an image processing device and method according to which it is possible to prevent an increase in the amount of code in a quantization matrix. This image processing device is provided with an up-converter for up-converting a quantization matrix, which is limited to a size equal to or smaller than the transmission size which is the largest size allowable during transmission, from the transmission size to a size equal to the block size which is the processing unit for quantization or reverse quantization. The present disclosure can be applied, e.g., to an image processing device for processing image data. |
