Control method, program, and display device for reproducing a moving image on foldable display

1. A moving image control method for controlling display of a moving image on a foldable display device, the foldable display device comprising an upper display, a lower display, and a fold portion between the upper display and the lower display, the moving image control method comprising:

acquiring moving image position information indicating a position in a display region at which the moving image is displayed; and

based on the moving image position information indicating that at least a portion of the moving image is displayed in the fold portion:

acquiring fold state information indicating a fold state including a fold angle of the foldable display device;

determining an apparent size of the moving image based on the fold angle included in the fold state information, the apparent size corresponding to a line segment that connects an upper end of the moving image and a lower end of the moving image and that is determined based on the fold angle included in the fold state information; and

controlling whether the moving image is stopped or reproduced in the display region based on the moving image position information and the apparent size of the moving image;

wherein the upper end of the moving image is in the upper display and the lower end of the moving image is in the lower display.

2. The moving image control method according to claim 1 , wherein the controlling is performed based on the apparent size of the moving image that varies as the foldable display device is folded.

3. The moving image control method according to claim 2 , wherein the moving image is stopped based on the apparent size of the moving image being less than or equal to a set size.

4. The moving image control method according to claim 2 , wherein the apparent size of the moving image varies based on the position in the display region at which the moving image is displayed.

5. The moving image control method according to claim 4 , wherein based on the display region being folded, the apparent size of the moving image changes based on the position in the display region at which the moving image is displayed.

6. The moving image control method according to claim 5 , further comprising performing control to stop the moving image based on the fold angle being less than or equal to a first angle.

7. The moving image control method according to claim 6 , further comprising performing control to reproduce the moving image based on the fold angle changing from less than or equal to the first angle to at least a second angle that is greater than the first angle.

8. The moving image control method according to claim 7 , further comprising ending display of the moving image based on the fold angle being less than or equal to a third angle that is smaller than the first angle.

9. The moving image control method according to claim 8 , wherein the controlling whether the moving image is stopped or reproduced is controlled based on a positional relationship between the position in the display region at which the moving image is displayed and a user of the foldable display device.

10. The moving image control method according to claim 1 , wherein the controlling whether the moving image is stopped or reproduced is based on a direction of a line of sight of a user of the foldable display device or a positional relationship between the foldable display device and the user.

11. The moving image control method according to claim 1 , wherein the controlling whether the moving image is stopped or reproduced is based on an orientation of the foldable display device.

12. The moving image control method according to claim 1 , further comprising displaying a user interface element that relates to the moving image at a position that is different from a folded position of the display region.

13. The moving image control method according to claim 1 , further comprising continuously displaying a frame image among a plurality of frame images that constitute the moving image while the moving image is stopped.

14. A non-transitory computer readable storage medium storing program instructions that are to be executed by a computer of a foldable display device to perform a moving image control method for controlling display of a moving image on the foldable display device, the foldable display device comprising an upper display, a lower display, and a fold portion between the upper display and the lower display, the moving image control method comprising:

acquiring moving image position information indicating a position in a display region at which the moving image is displayed; and

based on the moving image position information indicating that at least a portion of the moving image is displayed in the fold portion:

acquiring fold state information indicating a fold state including a fold angle of the foldable display device;

determining an apparent size of the moving image based on the fold angle included in the fold state information, the apparent size corresponding to a line segment that connects an upper end of the moving image and a lower end of the moving image and that is determined based on the fold angle included in the fold state information; and

controlling whether the moving image is stopped or reproduced in the display region based on the moving image position information and the apparent size of the moving image,

wherein the upper end of the moving image is in the upper display and the lower end of the moving image is in the lower display.

15. A display device comprising:

a foldable display panel comprising an upper display, a lower display, and a fold portion between the upper display and the lower display;

a memory configured to store computer-readable instructions; and

a processor configured to execute the computer-readable instructions to:

acquire moving image position information indicating a position in a display region at which the moving image is displayed on the foldable display panel; and

based on the moving image position information indicating that at least a portion of the moving image is displayed in the fold portion:

acquire fold state information indicating a fold state including a fold angle of the foldable display panel;

determine an apparent size of the moving image based on the fold angle included in the fold state information, the apparent size corresponding to a line segment that connects an upper end of the moving image and a lower end of the moving image and that is determined based on the fold angle included in the fold state information; and

control whether the moving image is stopped or reproduced in the display region based on the moving image position information and the apparent size of the moving image,

wherein the upper end of the moving image is in the upper display and the lower end of the moving image is in the lower display.
