Abstract
A read image of an original is compared by using a dictionary in which sample-image information is associated with a score indicating the quality of an image and stored, and the quality score of the read image of the original is calculated; and control is made such that the calculated quality score is presented to the user. Therefore, the quality of an image is evaluated in a stable manner.
