Abstract
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 stored format (stored image) stored. When it is determined as being similar, the document matching process section determines whether the entry omission is present in a part in the document image corresponding to a part defined in the stored image, and then outputs the determination result.
