Abstract
PURPOSE: To reduce erroneous read and read reject, by starting discrimination when conditions for character recognition are satisfied and by stopping discrimination of the preceding signal to use a new signal for discrimination when the next signal has better discrimination conditions.
CONSTITUTION: The character read by scanner 21 is quantized by quantizing circuit 23 and has width 241 and height 242 detected by character detection cutting part 24, and discrimination is started by discriminating part 25 if fixed conditions are satisified. When the next scan signal is input, this signal is compared with the signal from memory 244 where the height and the width of the character are stored; and if better conditions such as the character width wider than the preceding that within the allowable range are obtained, the character which is being discriminated by discriminating part 25 is abandoned, and a new signal is sent to discriminating part 25. Thus, erroneous read and read eject can be reduced because of discrimination under better conditions.
