Abstract

An apparatus for recognizing characters read by a reading unit. A circumscribing rectangle of a read character is formed, and the degree of narrowness of that circumscribing rectangle is acquired. Characters having a degree of narrowness that is equal to or greater than a predetermined value are selected and blank areas are added to the circumscribing rectangle to yield a character area with a corrected degree of narrowness. The character is normalized by converting the character area to a specified size, and is recognized based on the normalized character. It is therefore possible to normalize even characters significantly elongated vertically or horizontally for easier recognition and to group their character patterns.
