Abstract

In a paper sheet processing apparatus comprising a function for determining the state of a paper sheet, an optical sensor generates template data by optically reading the state of an input paper sheet. A template data unit stores template data of a paper sheet. An image processing unit corrects gradation data of the whole paper sheet based on the gradation data of a predetermined area of the paper sheet obtained by the optical sensor. Based on comparison of the corrected gradation data with the template data, the state of the paper sheet is determined.
