Abstract

A handwritten character recognition device comprises a feature point circuit for recognizing a character with using three feature points for a continuous stroke connecting a first stroke and second strokes. For recognition, both stroke information and stroke connection information between adjacent strokes are read-in per stroke. Therefore, the character can be recognized with a relative position correlation between the stroke number and the stroke shape. Even if the stroke number may be irregularly changed, the inputted character can be recognized without a necessity of storing information for the irregularly changed strokes.
