Abstract

According to one embodiment, an electronic apparatus includes a display processor. The display processor is configured to display one or more first strokes on a screen. The display processor is configured to display a plurality of candidates each indicative of one or more handwritten characters in a handwritten document, the plurality of candidates retrieved from the handwritten document by using the one or more first strokes, and is configured to arrange the plurality of candidates in an order determined by using number of strokes of each of the plurality of candidates and to display the plurality of arranged candidates.

Claims

1. An electronic apparatus comprising a display processor configured to display one or more first strokes on a screen,

wherein the display processor is configured to display a plurality of candidates each indicative of one or more handwritten characters in a handwritten document, the plurality of candidates retrieved from the handwritten document by using the one or more first strokes, and

is configured to arrange the plurality of candidates in an order determined by using number of strokes of each of the plurality of candidates and to display the plurality of arranged candidates.

2. The electronic apparatus of claim 1, wherein each of the plurality of candidates comprises a handwritten character string comprising one or more handwritten characters corresponding to the one or more first strokes, and one or more handwritten characters not corresponding to the one or more first strokes, and

the plurality of candidates are arranged in an order determined by using number of the one or more handwritten characters not corresponding to the one or more first strokes and the plurality of arranged candidates are displayed.

3. The electronic apparatus of claim 1, wherein the display processor is configured to display, in response to a selection of a first candidate from the plurality of displayed candidates, one or more second strokes constituting the first candidate by replacing the one or more first strokes with the one or more second strokes, on the screen.

4. The electronic apparatus of claim 1, wherein the display processor is configured to display one or more candidates of the plurality of candidates on the screen based on a feature amount corresponding to strokes constituting each of the plurality of candidates, the one or more candidates each having the feature amount of which a degree of similarity to the feature amount corresponding to the one or more first strokes is greater than or equal to a threshold, and

is configured to arrange the one or more candidates in an order corresponding to the number of strokes of each of the one or more of candidates, and to display the one or more arranged candidates.

5. The electronic apparatus of claim 1, wherein the plurality of candidates are further arranged in an order corresponding to at least one of the number of strokes of each of the plurality of candidates, a sum of lengths of strokes of each of the plurality of candidates, number of coordinates expressing strokes constituting each of the plurality of candidates, and time required to handwrite strokes constituting each of the plurality of candidates, and the plurality of arranged candidates are displayed.

6. A method comprising:

displaying one or more first strokes on a screen,

wherein the displaying comprises displaying a plurality of candidates each indicative of one or more handwritten characters in a handwritten document, the plurality of candidates retrieved from the handwritten document by using the one or more first strokes,

arranging the plurality of candidates in an order determined by using number of strokes of each of the plurality of candidates, and

displaying the plurality of arranged candidates.

7. The method of claim 6, wherein each of the plurality of candidates comprises a handwritten character string comprising one or more handwritten characters corresponding to the one or more first strokes, and one or more handwritten characters not corresponding to the one or more first strokes, and

the plurality of candidates are arranged in an order determined by using number of the one or more handwritten characters not corresponding to the one or more first strokes and the plurality of arranged candidates are displayed.

8. The method of claim 6, further comprising displaying, in response to a selection of a first candidate from the plurality of displayed candidates, one or more second strokes constituting the first candidate by replacing the one or more first strokes with the one or more second strokes, on the screen.

9. The method of claim 6, wherein the displaying comprises displaying one or more candidates of the plurality of candidates on the screen based on a feature amount corresponding to strokes constituting each of the plurality of candidates, the one or more candidates each having the feature amount of which a degree of similarity to the feature amount corresponding to the one or more first strokes is greater than or equal to a threshold,

arranging the one or more candidates in an order corresponding to number of strokes of each of the one or more candidates, and displaying the one or more arranged candidates.

10. The method of claim 6, wherein the plurality of candidates are further arranged in an order corresponding to at least one of the number of strokes of each of the plurality of candidates, a sum of lengths of strokes of each of the plurality of candidates, number of coordinates expressing strokes of each of the plurality of candidates, and time required to handwrite strokes constituting each of the plurality of candidates, and the plurality of arranged candidates are displayed.

11. A computer-readable, non-transitory storage medium having stored thereon a program which is executable by a computer, the program controlling the computer to execute functions of

displaying one or more first strokes on a screen,

wherein the displaying comprises displaying a plurality of candidates each indicative of one or more handwritten characters in a handwritten document, the plurality of candidates retrieved from the handwritten document by using the one or more first strokes,

arranging the plurality of candidates in an order determined by using number of strokes of each of the plurality of candidates, and

displaying the plurality of arranged candidates.

12. The storage medium of claim 11, wherein each of the plurality of candidates comprises a handwritten character string comprising one or more handwritten characters corresponding to the one or more first strokes, and one or more handwritten characters not corresponding to the one or more first strokes, and

the plurality of candidates are arranged in an order determined by using number of the one or more handwritten characters not corresponding to the one or more first strokes and the plurality of arranged candidates are displayed.

13. The storage medium of claim 11, wherein the program controlling the computer to further execute functions of displaying, in response to a selection of a first candidate from the plurality of displayed candidates, one or more second strokes constituting the first candidate by replacing the one or more first strokes with the one or more second strokes, on the screen.

14. The storage medium of claim 11, wherein the displaying comprises displaying one or more candidates of the plurality of candidates based on a feature amount corresponding to strokes constituting each of the plurality of candidates, the one or more candidates each having the feature amount of which a degree of similarity to the feature amount corresponding to the one or more first strokes is greater than or equal to a threshold,

arranging the one or more candidates in an order corresponding to number of strokes of each of the one or more candidates, and displaying the one or more arranged candidates.

15. The storage medium of claim 11, wherein the plurality of candidates are further arranged in an order corresponding to at least one of the number of strokes of each of the plurality of candidates, a sum of lengths of strokes of each of the plurality of candidates, number of coordinates expressing strokes constituting each of the plurality of candidates, and time required to handwrite strokes constituting each of the plurality of candidates, and the plurality of arranged candidates are displayed.
