Information display device and document data editing method
First Claim
1. An information display device comprising:
- a display screen for displaying a character string;
operation position detecting means adapted to detect an operation position on said display screen;
character string selecting means adapted to, when two operations are simultaneously performed on said display screen, and two different operation positions are detected, on a basis of said detected operation positions, select a character string including one or more characters, the character string being displayed on said display screen;
pinch operation detecting means adapted to, on a basis of a change in a distance between said operation positions, detect a pinch in operation that narrows the distance between said operation positions, and a pinch out operation that enlarges the distance; and
character string converting means adapted to, on a basis of a result of the detection by said pinch operation detecting means, performs a conversion process of said selected character string, said conversion process is opposite to each other when said pinch in operation is detected and when said pinch out operation is detected, respectively, whereinin a case where the pinch in operation is detected, the character string converting means converts an upper case character in the character string into a corresponding lower case character, andin a case where the pinch out operation is detected, the character string converting means converts a lower case character in the character string into a corresponding upper case character.

Abstract
Provided are an information display device and a character string converting method that improve operability at the time of changing a character string on a display screen.
The information display device is configured to have: a display screen 12 for displaying a character string; a touch panel controller 27 that detects an operation position; a character string selecting part 34 that, when two different operation positions are detected, on the basis of a result of the detection of the operation positions, selects a character string on the display screen 12; and a character string converting part 36 that, when a distance between the two operation positions is changed, converts the character string selected by the character string selecting part 34 depending on whether the change is a change that causes the distance between the operation positions to be narrowed or enlarged. For example, the character string converting part 36 converts a full-width character in the character string to a half-width character in the case where the change in distance between the two operation positions is the change that causes the distance between the operation positions to be narrowed, and converts a half-width character in the character string to a full-width character in the case where the change is the change that causes the distance between the operation positions to be enlarged.

3. An information display device comprising:
-
a display screen for displaying a character string; operation position detecting means adapted to detect an operation position on said display screen; character string selecting means adapted to, when two operations are simultaneously performed on said display screen, and two different operation positions are detected, on a basis of said detected operation positions, select a character string including one or more characters, the character string being displayed on said display screen; pinch operation detecting means adapted to, on a basis of a change in a distance between said operation positions, detect a pinch in operation that narrows the distance between said operation positions, and a pinch out operation that enlarges the distance; and character string converting means adapted to, on a basis of a result of the detection by said pinch operation detecting means, performs a conversion process of said selected character string, said conversion process is opposite to each other when said pinch in operation is detected and when said pinch out operation is detected, respectively, wherein; said display screen horizontally displays the character string; said character string selecting means selects a character string including one or more characters when two horizontally separated operation positions are detected, and when two vertically separated operation positions are detected, selects a character string including one character; and said character string converting means performs conversion processes different from each other when horizontal pinch operation is detected and when vertical pinch operation is detected, respectively. - View Dependent Claims (4)

5. An information display device comprising:
-
a display screen for displaying a character string; operation position detecting means adapted to detect an operation position on said display screen; character string selecting means adapted to, when two operations are simultaneously performed on said display screen, and two different operation positions are detected, on a basis of said detected operation positions, select a character string including one or more characters, the character string being displayed on said display screen; pinch operation detecting means adapted to, on a basis of a change in a distance between said operation positions, detect a pinch in operation that narrows the distance between said operation positions, and a pinch out operation that enlarges the distance; and character string converting means adapted to, on a basis of a result of the detection by said pinch operation detecting means, performs a conversion process of said selected character string, said conversion process is opposite to each other when said pinch in operation is detected and when said pinch out operation is detected, respectively, wherein said character string converting means converts a full-width character in the character string to a corresponding half-width character when said pinch in operation is detected, and when said pinch out operation is detected, converts a half-width character in the character string to a corresponding full-width character.
