Abstract
A system (10) for recognizing numerical characters which appear as both numerical characters and words on a document includes an image capture device (12) for capturing the image of a document. A recognition circuit (14) performs recognition of the numerical characters. A recognition circuit (16) performs recognition of the words corresponding to the numerical characters. A comparator circuit (20) compares the recognition signals generated by the recognition circuit (16) to the recognition signals generated by the recognition circuit (14) to determine if the numerical characters recognized by the recognition circuit (14) is correct.
