摘要： PROBLEM TO BE SOLVED: To provide a high-accuracy recognition and also to provide an on-line character recognizing device capable of a high-speed recognition by providing a step, etc., for outputting a standard character selected in a character form recognition step corresponding to the degree of similarity calculated in a stroke order mutual correspondence recognition step. SOLUTION: Based on a stroke sequence sent from a control means 59, a character form recognizing means 52 outputs candidate characters from the distance between a standard pattern in a character form dictionary and an input pattern. The control means 59 sends the candidate characters to a stroke order mutual correspondence recognizing means 54 and at this means 54, the features of respective strokes are extracted from the input pattern. Next, the strokes are collated with the standard pattern in a stroke feature dictionary 53 for candidate characters. At a character form recognizing means 52, the number of strokes are collated and when they are coincident, they are made to correspond to each other using the standard pattern, etc., in the stroke feature dictionary 53. Next, the distance between the stroke features of both the input and standard patterns is calculated, the distance between the respective features is weighted, and the final distance to the standard pattern is found.

摘要： PROBLEM TO BE SOLVED: To update a standard dictionary suitably even if a similar character is present by updating the standard dictionary suitably on the basis of the information of a similar character information storage table. SOLUTION: When a control means 9 actuates a dictionary updating means, an opposite character selecting means 21 selects an opposite character from the recognition result obtained by a dictionary matching means 4. An update control means 30 actuates an opposite character distance decision means 22 to compares the distance value of the opposite character with a previously set threshold value. The update control means 30 actuates a table retrieval means 26 to retrieve information of a combination of a correct character and the opposite character from the similar character information storage table 7. This similar character information is used to update the standard dictionary only when a proper pattern is inputted. If the combination of the correct character and opposite character is not retrieved from the similar character information storage table 7, similar character information is newly registered in the storage table 7 and a storage buffer 20.
