Abstract

A non-transitory computer-readable medium storing a selected character specification program that causes a computer to execute a process including detecting a character region indicating a region, in which each character of the displayed character string is displayed on a screen, based on character string display information, specifying a stroke of a closed curved line designated on the screen based on input operation information, and specifying one or a plurality of successive characters, in which a ratio of an area of a selected region based on uppermost, lowermost, leftmost, and rightmost points of the stroke of the closed curved line in the character region to an area of the character region exceeds a threshold, as selected character among a respective character of the displayed character string overlapped with the stroke of the closed curved line.

Claims

1. A non-transitory computer-readable medium storing a selected character specification program that causes a computer to execute a process comprising:

detecting a character region indicating a region, in which each character of the displayed character string is displayed on a screen;

specifying a stroke of a closed curved line designated on the screen based on input operation information; and

specifying one or a plurality of successive characters, in which a ratio of an area of a selected region to an area of the character region exceeds a threshold, the selected region representing a polygonal region that includes, as apexes, uppermost, lowermost, leftmost, and rightmost points in the character region of the stroke of the closed curved line, as selected character among a respective character of the displayed character string overlapped with the stroke of the closed curved line.

2. The non-transitory computer-readable medium storing the selected character specification program according to claim 1, wherein the selected region further represents a region overlapped between the character region and an internal region inscribed in the uppermost, lowermost, leftmost, and rightmost points of the stroke.

3. The non-transitory computer-readable medium storing the selected character specification program according to claim 1, wherein the process further comprises segmenting the specified selected characters into words based on a morpheme analysis and removing one or a plurality of characters, each of which does not constitute a word, at a beginning or an end of the selected characters from the selected characters.

4. The non-transitory computer-readable medium storing the selected character specification program according to claim 1, wherein the detecting the character region based on character string display information includes a position of a first character of the displayed character string, a character size of each character of the displayed character string, and space between lines of displayed character strings.

5. The non-transitory computer-readable medium storing the selected character specification program according to claim 4, wherein

the displayed character string includes a decorated character,

the character string display information further includes a position of the decorated character, a character size of the decorated character, and space between lines of the decorated character, and

the character region is detected for each character of the displayed character string including the decorated character in the detecting the character region.

6. The non-transitory computer-readable medium storing the selected character specification program according to claim 5, wherein the decorated character represents one or both of a character to which character size is expanded or reduced and a character affixed with a ruby.

7. A non-transitory computer-readable medium storing a selected character specification program that causes a computer to execute a process comprising:

detecting a character region indicating a region, in which each character of the displayed character string is displayed on a screen;

specifying one or a plurality of strokes designated on the screen based on input operation information; and

specifying one or a plurality of successive characters, in which a ratio of an area of a selected region to an area of the character region exceeds a threshold, the selected region representing a polygonal region that includes, as apexes, apexes of the character region and uppermost, lowermost, leftmost, and rightmost points in the character region of the one or the plurality of strokes, as selected character among a respective character of the displayed character string overlapped with the one or the plurality of strokes.

8. The non-transitory computer-readable medium storing the selected character specification program according to claim 7, wherein

the stroke represents any of a curved line, a broken line, and a straight line, and

the selected region further represents an overlapped region between the character region and a circumscribed rectangle region of the uppermost, lowermost, leftmost, and rightmost points of the stroke.

9. A selected character specification device comprising:

a memory; and

a processor coupled to the memory and configured to execute a process including;

detecting a character region indicating a region, in which each character of the displayed character string is displayed on a screen;

specifying a stroke of a closed curved line designated on the screen based on input operation information; and

specifying one or a plurality of successive characters, in which a ratio of an area of a selected region to an area of the character region exceeds a threshold, the selected region representing a polygonal region that includes, as apexes, uppermost, lowermost, leftmost, and rightmost points in the character region of the stroke of the closed curved line, as selected character among a respective character of the displayed character string overlapped with the stroke of the closed curved line.

10. A non-transitory computer-readable medium storing a selected character specification program that causes a computer to execute a process comprising:

detecting a character region indicating a region, in which each character of the displayed character string is displayed on a screen;

specifying one or a plurality of strokes designated on the screen based on input operation information; and

specifying one or a plurality of successive characters, in which a ratio of an area of a selected region to an area of the character region exceeds a threshold, the selected region representing a polygonal region that includes, as apexes, apexes of the character region and apexes of a circumscribed rectangle region of uppermost, lowermost, leftmost, and rightmost points in the character region of the one or the plurality of strokes, as a selected character among a respective character of the displayed character string overlapped with the one or the plurality of strokes.
