Abstract
A hand-written character recognition apparatus includes a CIS, and image data of each character of addressing information hand-written on a transmission original, which is read by the CIS, is stored in a bit-mapped line buffer. A histogram of one direction, e.g. an X direction (main scanning direction) is produced on the basis of the image data, and the histogram is stored in the histogram buffer. A rough position of each of the characters is evaluated on the basis of the histogram, and a character width of each of the characters, preferably an average character width is evaluated with referring to the line buffer. Then, a blank portion having a size of 1.5 times or less the average character width is detected as a space between characters.
