PROBLEM TO BE SOLVED: To make correcting efficient by extracting a character whose calculated conviction degree does not reach a specified value and outputting its recognition result and character image, side by side. SOLUTION: The character image is cut out of a binary image and stored in an image area of a RAM 5, and the sheet number of the sheet where the character image is present, the page number of the character in the same sheet, an image area, a start point, an end point, and an item are stored in a ROM 5. Character recognition is performed by referring to a dictionary in a storage device 6 and the result is stored as a recognition result. The feature quantity of the character image is extracted and compared with a standard feature quantity to calculate the degree of conviction, which is stored as a degree of conviction. The calculated conviction degree is compared with a threshold and in the case of 'conviction degree < threshold', a flag is set to '1' (ON). The input image and recognition result for which the flag is set ON are taken out of the RAM 5 by characters or items, sorted in the sorting order of the characters, and outputted to a display 8 or printer 9.
