The collation processing part 2 consists of a collation start position determining part 2a and a dictionary collating part 2b, and a collation start position of attribute information of segments is searched, detected, and determined in the collation start position determining part 2a, and the collation of attribute information is started from this determined segment position in order. A category of the dictionary pattern whose coincidence is decided by this collation is outputted as the recognition result of the graphic pattern. |
