Abstract

Provided is an operating method of a flexible display device including a display. The method includes: displaying, at a preview area of the display, a preview image corresponding to an object; expanding the display in an first direction according to detecting the display is expanded in the first direction; and capturing an image of the object when the display is expanded in the first direction.

First claim

What is claimed is:

1. A method of a flexible display device that includes a display, the method comprising:
displaying, at a preview area of the display, a preview image corresponding to an object;
expanding the display in a first direction according to detecting that the display is expanded in the first direction; and
automatically capturing the preview image of the object when a controller of the flexible display device detects that the display is expanded to a first predetermined distance in the first direction while the preview image is displayed on the display.

2. The method according to claim 1 , further comprising: if an expansion distance of the display is equal to or greater than a first predetermined distance, displaying the captured image of the object in an expansion area of the display, the expansion area of the display corresponds to the expansion distance.

3. The method according to claim 1 , further comprising: if an expansion distance of the display is less than a first predetermined distance, displaying the captured image of the object in the preview area of the display and simultaneously displaying image editing menus in an expansion area of the display corresponding to the expansion distance, and the image editing menus is for editing the captured image of the object.

4. The method according to claim 3 , further comprising: detecting that the display is additionally expanded in the first direction;
if the expansion distance is greater than the first predetermined distance according to detecting that the display is additionally expanded; and
displaying the captured image of the object in an expansion area of the display, the expansion area corresponds to an expansion distance that is greater than the first predetermined distance.

5. The method according to claim 2 , further comprising
receiving a request to select an image displayed in the expansion area;
detecting that the display is reduced in a second direction that is different than the first direction; and
storing the selected image according to detecting that the display is reduced in the second direction.

6. The method according to claim 5 , further comprising:
deleting an unselected image according to detecting that the display is reduced in the second direction.

7. The method according to claim 2 , wherein displaying the captured image of the object in the expansion area includes displaying a plurality of continuously captured images in a plurality of expansion areas.

8. The method according to claim 7 , wherein a total number of the displayed plurality of continuously captured images varies based on a size of the preview area of the display.

9. A flexible display device comprising: a camera configured to capture an image of an object while in a capturing mode;
a display configured to expand in size or to reduce in size; a sensor configured to detect that the display is expanded or reduced; and a controller configured to control the camera, the display and the sensor, and the controller is configured to:
display a preview image corresponding to the object in a preview area of the display while in the capturing mode,
expand the display in a first direction according to detecting that the display is expanded in the first direction, and
automatically capture the preview image of the object when the controller detects that the display is expanded to a first predetermined distance in the first direction while the preview image is displayed on the display.

10. The flexible display device according to claim 9 , wherein if an expansion distance of the display is equal to or greater than a first predetermined distance, the controller controls the display to display the captured image of the object in an expansion area of the display, the expansion area of the display corresponds to the expansion distance.

11. The flexible display device according to claim 9 , wherein if an expansion distance of the display is less than a first predetermined distance, the controller controls the display to display the captured image of the object in the preview area of the display and to simultaneously display image editing menus in an expansion area of the display, and the image editing menus is for editing the captured image of the object.

12. The flexible display device of claim 11 , wherein the controller detects that the display is additionally expanded in the first direction and controls the display to display the captured image of the object in an expansion area of the display, the expansion area corresponds to an expansion distance that is greater than the first predetermined distance.

13. The flexible display device of claim 10 , further comprising a storage for storing the image,
wherein the controller receives a request for selecting an image displayed in the expansion area, and the controller stores the selected image in the storage according to detecting that the display is reduced in the second direction.

14. The flexible display device according to claim 13 , wherein the controller controls the storage device to delete an unselected image according to detecting that the display is reduced in the second direction.

15. The flexible display device according to claim 10 , wherein the controller controls the display to display a plurality of continuously captured images in a plurality of expansion areas.

16. The flexible display device according to claim 15 , wherein a total number of the displayed plurality of continuously captured images varies based on a size of the preview area.
