PURPOSE:To improve a recognition ratio by attaching a direction code to the outline part of an input pattern, taking the histogram of the direction code at every divided block of the input pattern, counting the number of times when a difference between the histogram and that of a previously prepared dictionary comes to '0' or below a prescribed value, and deciding a candidate by means of the discrete value. CONSTITUTION:In character recognition in an optical character reader and the like, the direction code is attached to the outline part of the input pattern, the histogram of the direction code is taken at every divided block of the input pattern, and the number of times when the difference of the histogram and that of the previously prepared dictionary comes to '0' or below the prescribed value is counted, whereby the candidate is decided by the discrete value. Thus, the characters which generate erroneous recognition in a distance operation can accurately be recognized.
