Abstract
After an optical character reader scans a line and image data corresponding thereto are stored, vacant regions perpendicular to the direction of the line are identified. Thereafter, candidate character positions are identified firstly by starting from the beginning of the line and secondly by starting from the end thereof. If the results of the two analyses coincide, they are identified as character positions where neighboring characters are separated. If they do not, a pattern matching method is used with stored patterns at each candidate character position to determine whether it really represents a character position.
