Abstract

An information processing device including an operation unit in which an operation input is possible by a touch operation on an operating surface; and a control unit that executes processing corresponding to an operation input performed via the operation unit, wherein the control unit causes, if an area of a portion that is in contact with the operating surface accompanying a touch operation is obtained and a touch operation in which the area is equal to or greater than a predetermined value is performed, restoration information for later restoring the display contents of a screen that are currently being displayed on a display unit to be stored in a memory unit, and display contents of a screen are restored, according to an operation input performed via the operation unit, based on the restoration information recorded in the memory unit.

Claims

1. An information processing device comprising:

an operation unit that receives an operation input, the operation input comprising a touch operation on an operating surface; and

a control unit that executes processing corresponding to the operation input when an area of contact on the operating surface during the touch operation is equal to or greater than a predetermined area, the processing comprising;

storing restoration information related to a display content that is being displayed at a point in time on a display screen of a display unit, the restoration information including a scrolling amount of a range of the display content that is being displayed at the point in time; and

restoring the display content based on the stored restoration information,

wherein if the control unit determines that a length of a drag of the touch operation is equal to or greater than a predetermined length and a direction of the drag of the touch operation is performed in a predetermined direction the control unit stores the restoration information in a memory unit,

wherein the restoration information includes information for restoring the display content at the point in time to a state in which a second operation input is possible,

wherein the operation unit receives the second operation input, the second operation input comprising a second touch operation on the operating surface, and

wherein the second operation input is a same type of operation as the first operation input.

2. The information processing device according to claim 1,

wherein restoration information further includes a screen capture image obtained by capturing a screen that is being displayed on the display unit at the point in time.

3. The information processing device according to claim 2, wherein the control unit:

determines whether the touch operation was performed with one finger or two fingers;

stores the screen capture image as the restoration information if the control unit determines that the touch operation was performed with one finger; and

stores the screen capture image and operation information as the restoration information if the control unit determines that the touch operation was performed with two fingers, the operation information including information for restoring the display content such that a second operation input similar to the operation input can be performed to the restored display content.

4. An information processing device comprising:

an operation unit that receives an operation input, the operation input comprising a touch operation on an operating surface; and

a control unit that executes processing corresponding to the operation input when an area of contact on the operating surface during the touch operation is equal to or greater than a predetermined area, the processing comprising;

storing restoration information related to a display content that is being displayed at a point in time on a display screen of a display unit; and

restoring the display content based on the stored restoration information,

wherein the restoration information includes information for restoring the display content at the point in time to a state in which a second operation input is possible,

wherein the operation unit receives the second operation input, the second operation input comprising a second touch operation on the operating surface,

wherein the second operation input is a same type of operation as the first operation input, and

wherein in a case when the display content is a document display screen, the control unit obtains, as the restoration information, at least identification information of a document that is currently being displayed and display range information that indicates a range, out of a document, that is currently being displayed, to be stored as the restoration information.

5. The information processing device according to claim 4,

wherein in a case when the display content is a movie reproduction screen or a music reproduction screen, the control unit obtains, as the restoration information, at least identification information of a movie or identification information of sounds that are being reproduced at the point in time and reproduction position information of a movie or reproduction position information of music that is being reproduced at the point in time , to be stored as the restoration information.

6. The information processing device according to claim 4,

wherein in a case when the display content is a still image display screen, the control unit obtains, as the restoration information, at least identification information of a still image that is being displayed at the point in time and zoom information of a still image, to be stored as the restoration information.

7. The information processing device according to claim 4,

wherein in a case when the display content is a web browser screen, the control unit obtains, as restoration information, at least an address of a webpage that is being displayed at the point in time and display range information that indicates a range, out of a webpage, that is being displayed at the point in time, to be stored as the restoration information.

8. An information processing device comprising:

an operation unit that receives an operation input, the operation input comprising a touch operation on an operating surface; and

a control unit that executes processing corresponding to the operation input when an area of contact on the operating surface during the touch operation is equal to or greater than a predetermined area, the processing comprising;

storing restoration information related to a display content that is being displayed at a point in time on a display screen of a display unit; and

restoring the display content based on the stored restoration information,

wherein the restoration information includes information for restoring the display content at the point in time to a state in which a second operation input is possible,

wherein the operation unit receives the second operation input, the second operation input comprising a second touch operation on the operating surface,

wherein the second operation input is a same type of operation as the first operation input, and

wherein the control unit causes a screen capture image obtained by capturing a screen that is being displayed at the point in time to be displayed on a screen when the area of contact on the operating surface during the touch operation is equal to or greater than the predetermined area, and once a predetermined amount of time has passed, causes a thumbnail capture image obtained by making a thumbnail of the screen capture image to be pasted to a tray displayed on the screen, and a capture icon obtained by making the thumbnail capture image an icon is caused to be pasted, according to a thirdoperation input performed via the operation unit, to a predetermined screen and the restoration information is caused to correspond with the capture icon and be stored in a memory unit.

9. The information processing device according to claim 8,

wherein the control unit reads, when the capture icon is selected by an operation input performed via the operation unit, the restoration information made to correspond with the capture icon from the memory unit, and restores display contents of a screen based on the restoration information.
