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.

First claim

The invention claimed is:

1. An information processing apparatus comprising:
at least one processor coupled to at least one memory, the at least one processor being programmed to perform division and enlargement processing, and
display an image;
detect a touch of at least three points;
detect an operation in which three different points on the displayed image are touched and, while fixing one of the three points, a pinch-out is performed with the remaining two points; and
in response to detection, perform control to display 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 control displays side by side the first display image and the second display image.

2. The information processing apparatus according to claim 1 , wherein the at least one processor is further programmed to, in response to the detection, divide a display screen displaying the image into a first screen for displaying the first display image and a second screen for displaying the second display image, and
wherein the first and second display images are displayed respectively in the divided first and second screens.

3. The information processing apparatus according to claim 2 , wherein, after a screen is divided, 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, 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 , wherein the at least one processor is further programmed to, in response to an operation in which a dividing line indicating a boundary between the divided first and second screens 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 the at least one processor is further programmed to, in response to a pinch-in operation with two points touched over a dividing line indicating a boundary between the divided first and second screens, delete 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 the at least one processor is further programmed to, 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 divided first and second screens, delete the first screen to display one screen based on the second screen.

8. The information processing apparatus according to claim 2 , wherein the at least one processor is further programmed to, 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 divided first and second screens, delete 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 to perform division and enlargement processing, the information processing apparatus comprising:
at least one processor coupled to at least one memory, the at least one processor being programmed to
display an image;
detect a touch;
detect an operation in which, while fixing one touched point on the displayed image, a touch for enlarging the image is performed;
in response to detection, divide a display screen displaying the image into a first screen and a second screen; and
display in the first screen a first image enlarged in response to the touch for enlarging the image, and 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 that performs division and enlargement processing, 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
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.

12. A non-transitory computer-executable program for controlling display of an image displayed on a display unit of an information processing apparatus that performs division and enlargement processing 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.
