Abstract
PURPOSE: To facilitate the correction input operation to reduce errors of operations, by displaying candidate characters to be recognized which are referred to for an unreadable character pattern in the character recognition process on the display device, to determine a candidate character whether it is adopted as the recognition result or not by the key operation.
CONSTITUTION: The character pattern on read sheet 1 is read and scanned by photoelectric converting part 2 to output the picture signal, and this picture signal is preprocessed by preprocessing part 3 to obtain quantized image data. This data is supplied to character recognizing part 5, and recognition candidate characters from dictionary part 4 are referred to recognize the character. When the character pattern read by recognizing part 5 cannot be read, the character pattern is applied to read character recognizing part 7, and candidate character information approximating the correct read result in dictionary part 4 is input to candidate character storing part 6, and the input character pattern and candidate character information are displayed on display part 10 by the control of control part 9, and it is determined whether candidate characters should be adopted or not by the key operation of input part 8.
