IMAGE PROCESSING APPARATUS AND METHOD THEREOF |
| 摘要 |
Pattern information of a color filter array and algorithm information of color interpolation processing used in photography of input image data are obtained. Comparative image data is generated from the input image data using the pattern information and algorithm information. The comparative image data and input image data are compared to detect alteration of the input image data. |
