The recognition rate is improved and recognition errors are suppressed when recognizing magnetic ink characters. A character recognition unit calculates a total difference by calculating the total of the differences between the character waveform data and the reference waveform data for each magnetic ink character within the area of one character; calculates a partial difference by summing the differences between character waveform data and reference waveform data in a target area, which is the area corresponding to a stroke that is 2 mesh or more wide in the area of one character; executing a correction process that reduces the value of the partial difference; and recognizing the candidate character as the magnetic ink character that was read when the total difference after the correction process is less than or equal to a threshold value. |
