The quality of an image read from a degraded image of an original document can be improved. Hence, a specific pixel of an image is selected, and additional information to be added to the image is generated from the position information and color information of the selected pixel. The image of an original document is read, position information and color information added to the original document are extracted, and the color information of a pixel corresponding to the position information is acquired from the read image. The color of the read image is corrected based on the extracted color information and the acquired color information. |
