Abstract

There is disclosed an apparatus for image reading or processing, that can precisely identify the pattern of a particularly pattern, such as of banknotes or securities of which faithful copying is to be pro-hibited. The apparatus is provided with a detecting unit for detecting the positional information of the original image, and a discriminating unit for extracting the pattern data of a certain part of the original image and discriminating whether the original image is the predetermined image, based on the similarly between the pattern data and a predetermined pattern.
