Title PROGRAM, INFORMATION STORAGE MEDIUM, AND INFORMATION PROCESSING APPARATUS
Abstract This information processing apparatus includes: a line cutout unit that cuts out a line from a keystroke string on the basis of the length of an off-keystroke between keystrokes in the inputted keystroke string; and a line integration unit that calculates a distance in a vertical direction between the center of the circumscribed rectangle of the cut out n-th (n is a natural number) line and the center of the circumscribed rectangle of the n+1-th keystroke string, and integrates the n-th keystroke string and the n+1-th keystroke string into the same line when the calculated distance is less than a predetermined threshold.
Scope of claims [claim1]
1. Handwritten, being the program in order to do the processing which quarries out line from the stroke line of the numerical formula which covers the plural lines which are input,
The line detection section which does the processing which quarries out line from the aforementioned stroke line on the basis of the length in off stroke between the strokes in the aforementioned stroke line, and,
N which is quarried out (as for n natural number) circumscribed rectangle in the stroke line of the line eye or circumscribed rectangle in the stroke in the particular stroke line and, m (m n the natural number which differs) circumscribed rectangle in the stroke line of the line eye or, it judges whether or not the stroke line of the n line eye and the stroke line of m line eye are identical line circumscribed rectangle in the stroke in the particular stroke line on the basis of the relationship of position, when it judges that it is identical line, with the stroke line of the n line eye and the stroke line of m line eye the line integration processing which is integrated to identical lineAs the line integrated section which is done the program which features that functioning it can point the computer.
[claim2]
2. In claim 1,
As for the aforementioned line integrated section,
The distance which circumscribed rectangle in the stroke line of the n line eye which is quarried out and circumscribed rectangle in the stroke line of the n+1 line eye calculated the distance of vertical direction, calculated when it is smaller than specified threshold, the program which features that the line integration processing which integrates the stroke line of the n line eye and the stroke line of the n+1 line eye to identical line is done.
[claim3]
3. Claim 1 or in 2,
As for the aforementioned line integrated section,
It decides whether or not the stroke which corresponds to fraction rule in the stroke line of the n line eye which is quarried out exists, whether when it decides that particular stroke exists, calculates with the distance of vertical direction of the circumscribed rectangular top in particular stroke, and the circumscribed rectangular bottom in the stroke line of m line eye and the circumscribed rectangular bottom in particular stroke and of the circumscribed rectangular top in the stroke line of m line eye the distance of vertical direction would like to seek the distance the gap which of when it is smaller than specified threshold, the stroke line of the n line eye and the stroke line of m line eyeThe program which features that the line integration processing which is integrated to identical line is done.
[claim4]
4. Claim either 1 or 3 in 1 sections,
As for the aforementioned line detection section,
The off stroke which becomes the line detection candidacy point on the basis of the length in off stroke between the strokes in the aforementioned stroke line, is decided, plural line detection candidacy are formed making use of the aforementioned line detection candidacy point,
As for the aforementioned line integrated section,
Plural aforementioned line detection candidacy concerning respectively doing numerical formula recognition the aforementioned line integration processing after doing, plural aforementioned line detection candidacy concerning respectively, certain of numerical formula it seems, it seeks, certain of numerical formula seems the program which features that the aforementioned line detection candidacy whose value is largest is selected.
[claim5]
5. Being computer reading possible information storage medium, claim either 1 or 4 the information storage medium which features that the program of 1 sections is remembered.
[claim6]
6. Handwritten, being the information processing equipment which does the processing which quarries out line from the stroke line of the numerical formula which covers the plural lines which are input,
The line detection section which does the processing which quarries out line from the aforementioned stroke line on the basis of the length in off stroke between the strokes in the aforementioned stroke line, and,
N which is quarried out (as for n natural number) circumscribed rectangle in the stroke line of the line eye or circumscribed rectangle in the stroke in the particular stroke line and, m (m n the natural number which differs) circumscribed rectangle in the stroke line of the line eye or, it judges whether or not the stroke line of the n line eye and the stroke line of m line eye are identical line circumscribed rectangle in the stroke in the particular stroke line on the basis of the relationship of position, when it judges that it is identical line, with the stroke line of the n line eye and the stroke line of m line eye the integration processing which is integrated to identical lineThe information processing equipment which features that the line integrated section which it does is included.
