PURPOSE:To accurately separate characters with high precision when the plural characters are combined, by detecting a difference analogical signal level through using a multiplied character pattern and by forcibly separating the characters at valley parts of the signal. CONSTITUTION:A photoelectric conversion signal of character information is outputted from a photoelectric conversion part 11 and then supplied to a quantitizing circuit 13 and an A/D converter 16 via an amplifier 12. This circuit 13 converts the conversion signal into a doubled character pattern, which is stored in a doubled pattern memory 14; and a converter 16 converts it into a multiplied character pattern, which is stored in a multiplied pattern memory 17. The output of the memory 14 is applied to a character detecting and segmenting circuit 15 and the horizontal and vertical projections of characters are formed to separate the characters, thereby discriminating whether the plural characters are combined or not. According to this discrimination output, a corresponding part in the memory 17 is addressed, and the multiplied character pattern addressed by a character separating circuit 18 is scanned successively to separate and output the characters accurately with high precision. |
