A handwritten character of each writer may have two or more characteristics and the characteristics are not always identical to those of a character in a correction history registered in the past. Thus, handwritten characters may not be recognized only by conventional character recognition. In the present invention, correction history data in which an identifier of a handwriting input device (device ID) used by a writer, image data on a handwritten character, and a character recognition code are associated with one another is managed in chronological order. Handwritten character images of the same writer and the same character code are extracted from the correction history data in chronological order starting from the latest image and the characteristics of the character images are detected, so that the characteristics of handwriting of a person are extracted.
