A document matching process section calculates feature points (e.g., the centroid) on the basis of an inputted document image, then selects a plurality of feature points from among the calculated feature points, and then calculates a hash value on the basis of the selected feature points. Then, on the basis of the calculated features, the document matching process section determines whether the document image is similar to a preliminary reference format (reference image). When it is determined as being similar, the document matching process section determines whether write-in is present in the document image, and then outputs a determination signal (a determination result indicating the presence or absence of write-in). In the determination of similarity of the document image, permission or non-permission for processing such as copying is determined more accurately than in the prior art.
An image processing apparatus for determining presence or absence of write-in in an obtained document image, comprising:
A non-transitory computer-readable memory product which stores a computer program for causing a computer to determine presence or absence of write-in in an obtained document image, wherein
