Abstract

A method for switching wallpaper in screen lock state, a mobile electronic device thereof, and a storage medium thereof are provided. In the present method, an input signal is received by a touch screen when a mobile electronic device enters a screen lock state. Then, whether the input signal is located in a specific area of the touch screen is determined. A moving track of the input signal is detected if the input signal is located in the specific area. Finally, wallpaper of the screen lock state is switched according to the moving track. As a result, a user can switch wallpaper arbitrarily even if the mobile electronic device is in the screen lock state, so as to increase convenience of switching wallpaper.

Claims

1. A method for switching wallpaper in a screen lock state, for a mobile electronic device having a touch screen, comprising:

receiving an input signal via the touch screen;

judging whether or not the input signal is located in a specific area of the touch screen;

detecting a moving track of the input signal if the input signal is located in the specific area; and

switching and displaying a wallpaper of the screen lock state according to the moving track.

2. The method for switching wallpaper in a screen lock state as claimed in claim 1, further comprising:

providing at least one candidate wallpaper; and

arranging the at least one candidate wallpaper in a sequence according to a picture information.

3. The method for switching wallpaper in a screen lock state as claimed in claim 2, wherein the picture information at least includes one of picture size, filing time of the picture and picture name.

4. The method for switching wallpaper in a screen lock state as claimed in claim 2, wherein the step of switching and displaying the wallpaper of the screen lock state according to the moving track comprise:

obtaining a moving direction of the moving track; and

sequentially switching and displaying the candidate wallpapers on the touch screen according to the moving direction, so as to display the wallpaper of the screen lock state.

5. The method for switching wallpaper in a screen lock state as claimed in claim 4, wherein the step of sequentially switching and displaying the candidate wallpapers on the touch screen comprise:

displaying a first plane of a 3D motion user interface on the touch screen, wherein the first plane displays one of the candidate wallpapers;

displaying the next candidate wallpaper on a second plane of the 3D motion user interface according to the sequence of the candidate wallpapers arranged based on the picture information, wherein the first plan and the second plane are two adjacent planes of the 3D motion user interface; and

processing an axial rotation on the 3D motion user interface according to the moving direction, so as to switch the first plane to the second plane.

6. The method for switching wallpaper in a screen lock state as claimed in claim 5, wherein the 3D motion user interface comprises a polyhedron.

7. The method for switching wallpaper in a screen lock state as claimed in claim 5, wherein the 3D motion user interface comprises a cube.

8. The method for switching wallpaper in a screen lock state as claimed in claim 5, wherein the axial rotation at least comprises one of a rotation along an X axis, a rotation along a Y axis and a rotation along a slanted axis.

9. The method for switching wallpaper in a screen lock state as claimed in claim 1, wherein the specific area comprises a wallpaper displaying area of the touch screen.

10. The method for switching wallpaper in a screen lock state as claimed in claim 9, wherein after step of switching and displaying the wallpaper, the method further comprises:

displaying a present time on a time displaying area of the touch screen, wherein the time displaying area partially covers the wallpaper displaying area.

11. A mobile electronic device, comprising:

a screen lock state switching module, for switching the mobile electronic device to a screen lock state;

a touch screen, coupled to the screen lock state switching module, for receiving an input signal under the screen lock state; and

a processing module, coupled to the touch screen, for judging whether or not the input signal is located in a specific area of the touch screen, detecting a moving track of the input signal if the input signal is located in the specific area, and switching and displaying a wallpaper of the screen lock state according to the moving track.

12. The mobile electronic device as claimed in claim 11, further comprising:

a storage unit, coupled to the processing module, for storing at least one candidate wallpaper, wherein the candidate wallpapers are arranged in a sequence according to a picture information.

13. The mobile electronic device as claimed in claim 12, wherein the picture information at least includes one of picture size, filing time of the picture and picture name.

14. The mobile electronic device as claimed in claim 12, wherein the processing module is used for obtaining a moving direction of the moving track, and sequentially switching and displaying the candidate wallpapers on the touch screen according to the moving direction, so as to display the wallpaper of the screen lock state.

15. The mobile electronic device as claimed in claim 14, wherein the processing module is used for displaying a first plane of a 3D motion user interface on the touch screen, wherein the first plane displays one of the candidate wallpapers, and used for displaying the next candidate wallpaper on a second plane of the 3D motion user interface according to the sequence of the candidate wallpapers arranged based on the picture information, wherein the first plan and the second plane are two adjacent planes of the 3D motion user interface, and further used for processing an axial rotation on the 3D motion user interface according to the moving direction, so as to switch the first plane to the second plane.

16. The mobile electronic device as claimed in claim 15, wherein the 3D motion user interface comprises a polyhedron.

17. The mobile electronic device as claimed in claim 15, wherein the 3D motion user interface comprises a cube.

18. The mobile electronic device as claimed in claim 15, wherein the axial rotation at least comprises one of a rotation along an X axis, a rotation along a Y axis and a rotation along a slanted axis.

19. The mobile electronic device as claimed in claim 11, wherein the specific area comprises a wallpaper displaying area of the touch screen.

20. The mobile electronic device as claimed in claim 19, wherein the processing module is used for displaying a present time on a time displaying area of the touch screen, wherein the time displaying area partially covers the wallpaper displaying area.

21. A storage medium, for storing a computer program including a plurality of program codes, the computer program being loaded to a mobile electronic device, so that the mobile electronic device executes a method for switching wallpaper in a screen lock state, the method comprising:

entering the screen lock state;

receiving an input signal via a touch screen of the mobile electronic device;

judging whether or not the input signal is located in a specific area of the touch screen;

detecting a moving track of the input signal if the input signal is located in the specific area; and

switching and displaying a wallpaper of the screen lock state according to the moving track.
