Abstract
A method for determining lines of character images in a recognition area for use in an optical character reader. In the line determining method, the character images in the recognition area are read by an image scanner so as to obtain image data of the character images in the recognition area. A circumscribed rectangular frame for enclosing each character is then determined based on the obtained image data so as to obtain coordinates of the circumscribed rectangular frame. Thereafter, circumscribed rectangular frames adjacent in a direction of the lines to each circumscribed rectangular frame are determined so as to obtain a connection relationship between the circumscribed rectangular frames as seen from each circumscribed rectangular frame, and then, the lines are determined based on the obtained connection relationship between the circumscribed rectangular frames.
