Abstract
A configuration is provided in which whether or not an article to be copied by a scanner is a copy-prohibited article such as a bill can be judged in a relatively short period of time. First, a copy object is prescanned by a scanner and read in rough pixel density, and with respect to the image, whether or not a copy object is a copy-prohibited article is checked. After completion of checking, main scanning is carried out to obtain a desired image of high density. As the result of the checking, the possibility that a copy object is a copy-prohibited article is examined, and when the possibility is low, said image of high density is output, and when the possibility is high, the image is checked again. As the result of checking, the possibility that a copy object is a copy-prohibited article is examined, and when the possibility is high, processing that the image is totally coated is carried out to output an unnormal image, and when the possibility is low, a normal image is output.
