in a case where the amount of rotation when the screen area is rotated in one direction exceeds the predetermined rotation amount, the processor disables the setting of the primary display area by the user input, and sets, as the primary display area, the other display area of the first display area and the second display area, which is not set as the primary display area.

2. The information processing device according to claim 1 , wherein

by executing the program stored in the memory, the processor further performs display mode switching processing to switch between a first display mode to control display by setting the screen area of the display as one display area, and the split display mode to control display by splitting the screen area of the display into the two display areas of the first display area and the second display area, and

in response to switching from the first display mode to the split display mode by the display mode switching processing, the processor displays, in the first display area, an active window in the first display mode by the display control processing.

3. The information processing device according to claim 2 , wherein

in response to switching from the first display mode to the split display mode by the display mode switching processing, the processor displays, in the second display area, thumbnail images corresponding to inactive windows other than the active window in the first display mode by the display control processing.

4. The information processing device according to claim 3 , wherein

when any of the thumbnail images displayed in the second display area in the split display mode is selected, the processor displays an inactive window corresponding to the selected thumbnail image as an active window in the second display area by the display control processing.

5. The information processing device according to claim 4 , wherein

when the active window is displayed in the second display area in the split display mode by the display control processing, the processor changes the display orientation of each of the first display area and the second display area according to a change in the orientation of the screen area without replacing pieces of display data to be displayed respectively in the first display area and the second display area, or

when the thumbnail images are displayed in the second display area in the split display mode, the processor replaces the pieces of display data to be displayed respectively in the first display area and the second display area, and changes the display orientation of each of the first display area and the second display area according to a change in up and down orientation of the screen area.

6. The information processing device according to claim 5 , wherein

the processor

displays operators as display mode choices inside the screen area by the display control processing to allow a user to instruct the first display mode or the split display mode, and replacement of the pieces of display data to be displayed respectively in the first display area and the second display area in the split display mode,

displays an operator corresponding to a current display mode in a display form distinguishable from the other operators, and

when the display mode is changed according to the change in the orientation of the screen area, displays an operator corresponding to a display mode after change in a display form distinguishable from the other operators.

7. A control method for an information processing device including: a foldable one display; a memory which stores at least a program; a processor which executes the program stored in the memory; and a sensor which detects orientation of the own information processing device, the control method comprising, by the processor executing the program stored in the memory:

detecting orientation of a screen area of the display based on the detection result of the sensor;

splitting the screen area into a plurality of display areas to display display-data in each of the display areas, respectively; and

changing display orientation of each of the plurality of display areas according to a change in the orientation of the screen area without replacing pieces of display data to be respectively output to the plurality of display areas, wherein

in a split display mode in which the screen area is split into two display areas of a first display area and a second display area to set, as a primary display area, either one of the first display area and the second display area, which is a display area set by user input,

in a case where the amount of rotation when the screen area is rotated in one direction according to a change in orientation of the screen area is less than a predetermined rotation amount, the processor sets either one of the first display area and the second display area, which is set as the primary display area by the user input, to be left as the primary display area, and

in a case where the amount of rotation when the screen area is rotated in one direction exceeds the predetermined rotation amount, the processor disables the setting of the primary display area by the user input, and sets, as the primary display area, the other display area of the first display area and the second display area, which is not set as the primary display area.

8. An information processing device comprising:

a foldable one display;

a memory which stores at least a program;

a processor which executes the program stored in the memory; and

a sensor which detects orientation of the own information processing device,

wherein,

by executing the program stored in the memory, the processor performs:

orientation detection processing to detect orientation of a screen area of the display based on the detection result of the sensor; and

display control processing in which the screen area is split into a plurality of display areas to display display-data in each of the plurality of display areas, respectively, and display orientation of each of the plurality of display areas is changed according to a change in the orientation of the screen area without replacing pieces of display data to be displayed respectively in the plurality of display areas,

by executing the program stored in the memory, the processor further performs display mode switching processing to switch between a first display mode to control display by setting the screen area of the display as one display area, and a second display mode to control display by splitting the screen area of the display into two display areas of a first display area and a second display area,
