Information processing device, information processing method, and information processing program

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.

• 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.
