Abstract

A mobile terminal including a touchscreen display unit configured to display at least a first image and to receive touch inputs, a projector module configured to project the first image displayed on the touchscreen display unit as a second image on an external surface, and a controller configured to detect a touch input on the touchscreen display unit, and to control the projector module to alter the displayed second image based on the detected touch input.

Claims

1. A mobile terminal comprising:

a touchscreen display unit configured to display at least a first image and to receive touch inputs;

a projector module configured to project the first image displayed on the touchscreen display unit as a second image on an external surface; and

a controller configured to detect a touch input on the touchscreen display unit, and to control the projector module to alter the displayed second image based on the detected touch input.

2. The mobile terminal of claim 1, wherein the controller is further configured to alter the second image by displaying an indicator on the second image corresponding to a same position touched on the first image displayed on the touchscreen display unit.

3. The mobile terminal of claim 1, wherein the controller is further configured to turn off the touchscreen display unit and only display the second image on the external surface based on a predetermined input operation performed on the mobile terminal.

4. The mobile terminal of claim 2, wherein the controller is further configured to shift the indicator displayed on the second image in correspondence with the detected touch input on the first image.

5. The mobile terminal of claim 1, wherein the controller is further configured to display an editing menu for editing the displayed second image on at least on the second image based on a predetermined input operation performed on the mobile terminal.

6. The mobile terminal of claim 1, wherein the controller is further configured to zoom in or zoom out the second image based on the detected touch input on the first image displayed on the touchscreen display unit.

7. The mobile terminal of claim 1, wherein the controller is further configured to highlight a portion of the second image based on the detected touch input on the first image displayed on the touchscreen display unit.

8. The mobile terminal of claim 7, wherein the controller is further configured to highlight the portion of the second image by drawing a shape around the portion of the second area based the detected touch input on the first image, and

wherein the detected touch input includes at least one of a touching and dragging operation from one point on the first image to a second point on the first image, and a multiple touching operation corresponding to a touching of the first and second points.

9. The mobile terminal of claim 7, wherein the controller is further configured to zoom in or zoom out the portion of the second image based on the detected touch input on the first image.

10. The mobile terminal of claim 1, wherein the controller is further configured to draw a line on the second image based the detected touch input on the first image displayed on the touchscreen display unit.

11. The mobile terminal of claim 1, wherein the controller is further configured to shift the second image based on the detected touch input on the first image displayed on the touchscreen display unit.

12. The mobile terminal of claim 1, wherein the controller is further configured to perform a predetermined operation on the second image based on the detected touch input on the first image displayed on the touchscreen display unit.

13. The mobile terminal of claim 1, wherein the detected touch input comprises at least one of a long touching operation, a multiple touching operation, a touch-and-drag operation, a touch-flicking operation and proximity touching operation.

14. A method of controlling a mobile terminal, the method comprising:

displaying at least a first image on a touchscreen display unit of the mobile terminal;

projecting the first image displayed on the touchscreen display as a second image on an external surface;

detecting a touch input on the touchscreen display unit; and

altering the displayed second image based on the detected touch input.

15. The method of claim 14, wherein the altering step alters the second image by displaying an indicator on the second image corresponding to a same position touched on the first image displayed on the touchscreen display unit.

16. The method of claim 14, further comprising:

turning off the touchscreen display unit and only displaying the second image on the external surface based on a predetermined input operation performed on the mobile terminal.

17. The method of claim 15, wherein the altering step shifts the indicator displayed on the second image in correspondence with the detected touch input on the first image.

18. The method of claim 14, further comprising:

displaying an editing menu for editing the displayed second image on at least on the second image based on a predetermined input operation performed on the mobile terminal.

19. The method of claim 14, wherein the altering step zooms in or zooms out the second image based on the detected touch input on the first image displayed on the touchscreen display unit.

20. The method of claim 14, wherein the altering step highlights a portion of the second image based on the detected touch input on the first image displayed on the touchscreen display unit.

21. The method of claim 20, wherein the altering step highlights the portion of the second image by drawing a shape around the portion of the second area based the detected touch input on the first image, and

wherein the detected touch input includes at least one of a touching and dragging operation from one point on the first image to a second point on the first image, and a multiple touching operation corresponding to a touching of the first and second points.

22. The method of claim 20, wherein the altering step zooms in or zooms out the portion of the second image based on the detected touch input on the first image.

23. The method of claim 14, wherein the altering step draws a line on the second image based the detected touch input on the first image displayed on the touchscreen display unit.

24. The method of claim 14, wherein the altering step shifts the second image based on the detected touch input on the first image displayed on the touchscreen display unit.

25. The method of claim 14, wherein the altering step performs a predetermined operation on the second image based on the detected touch input on the first image displayed on the touchscreen display unit.

26. The method of claim 14, wherein the detected touch input comprises at least one of a long touching operation, a multiple touching operation, a touch-and-drag operation, a touch-flicking operation and proximity touching operation.
