Method and apparatus for determining a predetermined pattern on an original based on visible and invisible information on the original
First Claim
Patent Images
1. An image processing apparatus comprising:
- first reading means for obtaining a first signal corresponding to visible information on an original;
second reading means for obtaining a second signal corresponding to invisible information on the original; and
comparing means for performing a comparison by using the first and second signals in order to discriminate a predetermined pattern, wherein said comparing means judges whether said second signal is based on the information obtained from the face of the original or on the information obtained from the back of the original.

Abstract
An image processor includes a first reader which obtains a first signal corresponding to visible information read on an original, and a second reader which obtains a second signal corresponding to invisible information on the original. A comparator compares the first and second signals to discriminate a predetermined pattern on the original.
