Abstract
An IR image input section inputs an IR image of printed matter P , using IR light having a near-infrared wavelength. An edge emphasizing section executes edge emphasizing processing on the IR image. A fold/wrinkle extracting section extracts pixels corresponding to a fold or a wrinkle from the edge-emphasized image, counts the number of the extracted pixels, measures the average density of the extracted pixels obtained when the IR image is input thereto, and outputs the number and the average density of the extracted pixels as feature quantity data. A determining section determines the soil degree of the printed matter P due to a fold or a wrinkle on the basis of the feature quantity data.
