The present invention pertains to an image processing device and method whereby it is possible to prevent a drop in image quality due to encoding and decoding. The present invention is provided with: a quantization unit which quantizes all the elements of a current block by using the weight coefficient of 1 when an orthogonal transformation process is skipped for the current block, and which quantizes each element of the current block by using a quantization matrix when the orthogonal transformation process is carried out on the current block; an encoding unit which encodes the coefficient of the current block which was quantized by means of the quantization unit; and a transfer unit for transferring the encoded data of the current block which was obtained by being encoded by means of the encoding unit. The present invention can be applied, for example, to an image processing device. |
