IMAGE PROCESSING APPARATUS AND METHOD CAPABLE OF FINELY ADJUSTING DATA COMPRESSION RATE |
| 摘要 |
<p>An image processing apparatus includes a coding part that performs coding on image data based on the result of decomposing the image data into bit planes block by block, and a quantization part that reduces the values of the image data of a predetermined block to be compressed at an increased rate. The quantization part is provided at an earlier stage than the coding part.</p> |
