Abstract
Abstract Disclosed is a method and an apparatus for recognizing and displaying handwritten characters and figures in which input stroke information on a handwritten input character or figure is read out by an electromagnetic tablet (3), recognition means (7) performs character/figure recognition on the basis of the feature of the input stroke information, display means (2) displays the input stroke information and the result of recognition, and when the result of recognition is displayed on a display screen of the display means, stroke information having been used for recognition is erased from the display screen, and stroke information which is not yet used for recognition, is left on the display screen.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
109 words
An apparatus for recognizing and displaying handwritten characters and figures which includes input means (3) for reading input stroke information as to a character and a figure each inputted by handwriting, recognition means (7) for carrying out character/figure recognition on the basis of the feature of the input stroke information, and display means (2) for displaying the input stroke information and the result of recognition, wherein when the result of recognition is displayed on a display screen of said display means, stroke information having been used for recognition is erased from said display screen, and stroke information which does not contribute to recognition is left on said display screen.
Claim 2
Independent Claim
109 words
An apparatus for recognizing and displaying handwritten characters and figures which includes input means (3) for reading input stroke information as to a character and a figure each inputted by handwriting, recognition means (7) for carrying out character/figure recognition on the basis of the feature of the input stroke information, and display means (2) for displaying the input stroke information and the result of recognition, wherein when the result of recognition is displayed on a display screen of said display means, stroke information having been used for recognition is erased from said display screen, and stroke information which does not contribute to recognition is left on said display screen.
Claim 3
Dependent Claim
35 words
An apparatus for recognizing and displaying handwritten characters and figures according to Claim 1, wherein the result of recognition is displayed after stroke information having been used for recognition is erased from said display screen.
Claim 4
Dependent Claim
78 words
An apparatus for recognizing and displaying handwritten characters and figures according to Claim 1, wherein information corresponding to stroke information having been used for recognition is sent from said recognition means to said display means when the result of recognition is sent from said recognition means to said display means, and said display means determines that part of the input stroke information which is to be erased from said display screen, on the basis of said corresponding information.
Claim 5
Dependent Claim
30 words
An apparatus for recognizing and displaying handwritten characters and figures according to Claim 3, wherein the number of strokes having been used for recognition is used as said corresponding information.
Claim 6
Dependent Claim
34 words
An apparatus for recognizing and displaying handwritten characters and figures according to Claim 3, wherein the number of position coordinates included in strokes having been used for recognition is used as said corresponding information.
Claim 7
Dependent Claim
69 words
An apparatus for recognizing and displaying handwritten characters and figures according to Claim 1, wherein the input stroke information is stored in and displayed on said display means in input order, and each time the result of recognition is sent from said recognition means to said display means, that part of said input stroke information stored in said display means which corresponds to said result of recognition is erased.
Claim 8
Dependent Claim
40 words
An apparatus for recognizing and displaying handwritten characters and figures according to Claim 3, wherein the number of strokes having been used for recognition and the number of position coordinates included in said strokes are used as said corresponding information.
Claim 9
Dependent Claim
45 words
An apparatus for recognizing and displaying handwritten characters and figures according to Claim 1, wherein said input means and said display means overlap each other to form a united body, and the input stroke information is displayed at the same place as inputted by handwriting.
Claim 10
Dependent Claim
60 words
An apparatus for recognizing and displaying handwritten characters and figures according to Claim 1, wherein each time stroke information is inputted, character/ figure recognition is carried out, and wherein each time character/figure recognition is completed, stroke information having been used for recognition is erased from said display screen, and then the result of recognition is displayed on said display screen.
Claim 11
Dependent Claim
179 words
A display method in an apparatus for recognizing and displaying handwritten characters and figures, said apparatus including input means (3) for reading input stroke information as to a character and a figure each inputted by handwriting, recognition means (7) for carrying out character/figure recognition on the basis of the feature of the input stroke information, and display means (2) for displaying the input stroke information and the result of recognition, said display method comprising the steps of: performing recognition processing in said recognition means each time said recognition means receives input stroke information from said input means; sending the result of recognition processing and one of the number of strokes having been used for the recognition processing and the number of position coordinates included in said strokes, to said display means, when said recognition processing is completed; and erasing stroke information having been used for said recognition processing, from a display screen of said display means, and displaying the result of recognition processing and stroke information which is being used for the next recognition processing, on said display screen.
Claim 12
Dependent Claim
179 words
A display method in an apparatus for recognizing and displaying handwritten characters and figures, said apparatus including input means (3) for reading input stroke information as to a character and a figure each inputted by handwriting, recognition means (7) for carrying out character/figure recognition on the basis of the feature of the input stroke information, and display means (2) for displaying the input stroke information and the result of recognition, said display method comprising the steps of: performing recognition processing in said recognition means each time said recognition means receives input stroke information from said input means; sending the result of recognition processing and one of the number of strokes having been used for the recognition processing and the number of position coordinates included in said strokes, to said display means, when said recognition processing is completed; and erasing stroke information having been used for said recognition processing, from a display screen of said display means, and displaying the result of recognition processing and stroke information which is being used for the next recognition processing, on said display screen.
