発明の名称 (英語) PROGRAM, INFORMATION STORAGE MEDIUM, AND RECOGNITION DEVICE
発明の概要(英語) Provided is a recognition device or the like which is capable of recognizing mathematical formulae including character strings. This recognition device includes: a registration unit which determines whether inputted strokes or stroke strings correspond to a specific gesture for demarcating a character string and a mathematical formula, and, in cases when the inputted strokes or stroke strings are determined to correspond to the specific gesture, registers information related to the range specified by the specific gesture; a demarcation unit which sets, as strokes corresponding to the character string, the strokes included in the range specified by the specific gesture among the inputted strokes, and sets, as strokes corresponding to the mathematical formula, the strokes not included in the range specified by the specific gesture; and a recognition unit which uses a character-string-recognition engine to recognize the character string from the strokes set as the strokes corresponding to the character string, and uses a mathematical-formula-recognition engine to recognize the mathematical formula from the stokes set as the strokes corresponding to the mathematical formula.
特許請求の範囲(英語) [claim1]
1. Handwritten, being the program in order to recognize the numerical formula which includes the character string from the stroke line which is input,
The register section which registers the information regarding the range which is appointed to the case where it decides that it decides, corresponds to aforementioned specific [jiesuchiya] whether or not the stroke or stroke line which is input, corresponds to specific [jiesuchiya] in order to divide with the character string and numerical formula, with aforementioned specific [jiesuchiya] and,
The division section which sets the stroke which is not included in the range which among the strokes which are input, sets the stroke which is included in the range which is appointed with aforementioned specific [jiesuchiya] is appointed with aforementioned specific [jiesuchiya] as the character string and the stroke to which numerical formula corresponds on the one hand, as the character string and the stroke to which numerical formula corresponds on the other hand and,
As the recognition section which recognizes numerical formula as the stroke which recognizes the character string as the stroke which corresponds to the character string from the stroke which is set with the character string recognition engine, corresponds to numerical formula with the numerical formula recognition engine from the stroke which is set the program which features that functioning it can point the computer.
[claim2]
2. In claim 1,
As for the aforementioned division section,
It sets the stroke which is included in the range which is appointed to the case where it is decided that the stroke or stroke line which is input corresponds to aforementioned specific [jiesuchiya], with particular specific [jiesuchiya], as the character string and the stroke to which numerical formula corresponds on the one hand when it is included in the range which it decides, is appointed with aforementioned specific [jiesuchiya] whether or not when it is decided that the stroke which is input does not correspond to aforementioned specific [jiesuchiya], it is included in the range where the stroke which is input particularly is appointed with aforementioned specific [jiesuchiya], the program which features that it sets the stroke which is input particularly as the character string and the stroke to which numerical formula corresponds on the one hand.
[claim3]
3. Claim in 1 or 2,
As for the aforementioned division section,
Among the strokes which are input, it sets the stroke which is included in the range which is appointed with aforementioned specific [jiesuchiya] as the stroke which corresponds to the character string, it sets the stroke which is not included in the range which is appointed with aforementioned specific [jiesuchiya] as the stroke which corresponds to numerical formula,
As for the aforementioned recognition section,
As one symbol handling the stroke which is included in the range which is appointed with one aforementioned specific [jiesuchiya], numerical formula is recognized with the numerical formula recognition engine the program which features that.
[claim4]
4. Claim either 1 or 3 in 1 sections,
Furthermore functioning point to the computer as the indicatory control section which does the control which makes the stroke line which is input in the indicatory department indicate,
As for the aforementioned indicatory control section,
The program which features that the control which it makes indicate the stroke or stroke line which is decided that it corresponds to aforementioned specific [jiesuchiya], as the picture which displays the form which corresponds to aforementioned specific [jiesuchiya] is done.
[claim5]
5. In claim 4,
As for the aforementioned indicatory control section,
The stroke which is included in the range which is appointed with aforementioned specific [jiesuchiya], the stroke which is not included in the range which is appointed with aforementioned specific [jiesuchiya] the program which features that the control which with the color which differs is made to indicate is done.
[claim6]
6. Claim either 1 or 5 in 1 sections,
As for the aforementioned register section,
The program which features that it decides that when the stroke or stroke line which is input forms abbreviation rectangle, particular stroke or the stroke line corresponds to aforementioned specific [jiesuchiya].
[claim7]
7. Being computer reading possible information storage medium, claim either 1 or 6 the information storage medium which features that the program of 1 sections is remembered.
[claim8]
8. Handwritten, being the recognition device which recognizes the numerical formula which includes the character string from the stroke line which is input,
The register section which registers the information regarding the range which is appointed to the case where it decides that it decides, corresponds to aforementioned specific [jiesuchiya] whether or not the stroke or stroke line which is input, corresponds to specific [jiesuchiya] in order to divide with the character string and numerical formula, with aforementioned specific [jiesuchiya] and,
The division section which sets the stroke which is not included in the range which among the strokes which are input, sets the stroke which is included in the range which is appointed with aforementioned specific [jiesuchiya] is appointed with aforementioned specific [jiesuchiya] as the character string and the stroke to which numerical formula corresponds on the one hand, as the character string and the stroke to which numerical formula corresponds on the other hand and,
The recognition device which features that the recognition section which recognizes numerical formula as the stroke which recognizes the character string as the stroke which corresponds to the character string from the stroke which is set with the character string recognition engine, corresponds to numerical formula from the stroke which is set with the numerical formula recognition engine is included.
