Abstract

When an information processing apparatus detects an operation in which three different points on a displayed image are touched and, while fixing one of the three points, the remaining two points are moved, the information processing apparatus displays side by side the image enlarged or reduced in response to the movement of the two points and the image neither enlarged nor reduced.

Claims

1. An information processing apparatus comprising:

a display unit configured to display an image;

a touch panel configured to detect a touch of at least three points;

a detection unit configured to detect an operation in which three different points on the image displayed on the display unit are touched and, while fixing one of the three points, a pinch-out is performed with the remaining two points; and

a display control unit configured to, in response to the detection by the detection unit, display on the display unit a first display image which is a partial image of the image and is an enlarged partial image including at least the center of the pinch-out, and a second display image which is a partial image of the image and is an unenlarged partial image including at least the one fixed point,

wherein the display control unit displays side by side the first display image and the second display image.

2. The information processing apparatus according to claim 1, further comprising:

a division unit configured to, in response to the detection by the detection unit, divide a display screen of the display unit displaying the image into a first screen for displaying the first display image and a second screen for displaying the second display image,

wherein the display control unit displays the first and second display images respectively in the first and second screens divided by the division unit.

3. The information processing apparatus according to claim 2, wherein, after a screen is divided by the division unit, in response to a scroll operation with a touch on the first screen, the first display image is scrolled while the second display image is not.

4. The information processing apparatus according to claim 2, wherein, after a screen is divided by the division unit, in response to a pinch-out operation on the first screen, the first display image is enlarged while the second display image is not.

5. The information processing apparatus according to claim 2, further comprising:

a changing unit configured to, in response to an operation in which a dividing line indicating a boundary between the first and second screens divided by the division unit is touched and slid, change the sizes of the first screen and the second screen.

6. The information processing apparatus according to claim 2, wherein, in response to a pinch-in operation with two points touched over a dividing line indicating a boundary between the first and second screens divided by the division unit, the display control unit deletes at least either one of the first screen and the second screen to display one screen.

7. The information processing apparatus according to claim 2, wherein, upon execution of a pinch-in operation while fixing one point on the first screen out of the two points touched over a dividing line indicating a boundary between the first and second screens divided by the division unit, the display control unit deletes the first screen to display one screen based on the second screen.

8. The information processing apparatus according to claim 2, wherein, upon execution of a pinch-in operation while fixing one point on the second screen out of the two points touched over a dividing line indicating a boundary between the first and second screens divided by the division unit, the display control unit deletes the second screen to display one screen based on the first screen.

9. The information processing apparatus according to claim 1, wherein the first display image includes detailed information about the image.

10. An information processing apparatus comprising:

a display unit configured to display an image;

a touch panel configured to detect a touch;

a detection unit configured to detect an operation in which, while fixing one touched point on the image displayed on the display unit, a touch for enlarging the image is performed;

a division unit configured to, in response to the detection by the detection unit, divide a display screen of the display unit displaying the image into a first screen and a second screen; and

a display control unit configured to display in the first screen a first image enlarged in response to the touch for enlarging the image, and to display in the second screen a second image which is an unenlarged image including at least the one fixed point.

11. A method for controlling display of an image displayed on a display unit of an information processing apparatus, the method comprising:

detecting an operation in which three different points on the image displayed on the display unit are touched and, while fixing one of the three points, a pinch-out is performed with the remaining two points; and

displaying on the display unit a first display image which is a partial and enlarged image of the image including at least the center of the pinch-out, and a second display image which is a partial and unenlarged image of the image including at least the one fixed point,

wherein the control displays side by side the first display image and the second display image.

12. A non-transitory computer-executable program for controlling display of an image displayed on a display unit according to a method comprising:

detecting an operation in which three different points on the image displayed on the display unit are touched and, while fixing one of the three points, a pinch-out is performed with the remaining two points; and

performing control for displaying on the display unit a first display image which is a partial and enlarged image of the image including at least the center of the pinch-out, and a second display image which is a partial and unenlarged image of the image including at least the one fixed point,

wherein the control displays side by side the first display image and the second display image.
