Abstract

A mobile terminal includes a projector module configured to project an image onto an external surface to display the image on the external surface and a controller configured to adjust at least one of an area or a position of the displayed image.

Claims

1. A mobile terminal comprising:

a projector module configured to project an image onto an external surface to display the image on the external surface; and

a controller configured to adjust at least one of an area or a position of the displayed image.

2. The mobile terminal of claim 1, wherein the displayed image of which the at least one of the area or the position is adjusted is a default image used for display adjustment, and the controller is further configured to display a selected image on the external screen via the projector module according to the adjusted at least one of the area or the position.

3. The mobile terminal of claim 1, further comprising:

a touchscreen configured to receive a touch input,

wherein the controller is further configured to receive a control signal corresponding to the touch input and the control signal is for adjusting the at least one of the area or the position of the displayed image.

4. The mobile terminal of claim 1, further comprising:

an image capturing device configured to receive a motion input,

wherein the controller is further configured to receive a control signal corresponding to the motion input and the control signal is for adjusting the at least one of the area or the position of the displayed image.

5. The mobile terminal of claim 1, further comprising:

a sound input device configured to receive a voice input,

wherein the controller is further configured to receive a control signal corresponding to the voice input and which is used for adjusting the at least one of the area or the position of the displayed image.

6. The mobile terminal of claim 1, further comprising:

a sensing unit configured to recognize movement of the mobile terminal,

wherein the controller is further configured to receive a control signal corresponding to the movement and which is used for adjusting the at least one of the area or the position of the displayed image.

7. The mobile terminal of claim 1, further comprising:

a display configured to display the image,

wherein the controller is further configured to display an interface for adjusting the at least one of the area or the position of the displayed image on at least one of the display or the external surface.

8. The mobile terminal of claim 7, further comprising:

an input unit configured to receive an input for adjusting the area and a ratio of the image,

wherein the controller is further configured to display the image on the external surface according to a default setting value, the default setting value being adjustable to one of a plurality of setting values responsive to the input.

9. A mobile terminal comprising:

a wireless communication unit configured to transmit an image that is displayable on an external surface and a control signal to the external surface; and

a controller configured to adjust the at least one of the area or the position of the image displayed on the external surface responsive to the control signal.

10. A method for projecting an image on an external surface via a mobile terminal comprising a projector module, the method comprising:

projecting an image onto an external surface to display the image onto the external surface;

adjusting at least one of an area or a position of the displayed image; and

displaying the image according to the adjusted at least one of the area or position.

11. The method of claim 10, further comprising:

selecting an image to be displayed on the external surface; and

displaying the selected image on the external surface,

wherein the displayed image of which the at least one of the area or the position is adjusted is a default image used for display adjustment.

12. The method of claim 10, further comprising:

receiving a touch input on a touchscreen of the mobile terminal; and

receiving a control signal corresponding to the touch input,

wherein the at least one of the area or the position of the displayed image is adjusted responsive to the control signal.

13. The method of claim 10, further comprising:

receiving a motion input via an image capturing device of the mobile terminal; and

receiving a control signal corresponding to the motion input,

wherein the at least one of the area or the position of the displayed image is adjusted responsive to the control signal.

14. The method of claim 10, further comprising:

receiving a voice input via a sound input device of the mobile terminal; and

receiving a control signal corresponding to the voice input,

wherein the at least one of the area or the position of the displayed image is adjusted responsive to the control signal.

15. The method of claim 10, further comprising:

recognizing movement of the mobile terminal via a sensing unit of the mobile terminal; and

receiving a control signal corresponding to the movement,

wherein the at least one of the area or the position of the displayed image is adjusted responsive to the control signal.

16. The method of claim 10, further comprising:

displaying the image via a display of the mobile terminal; and

displaying an interface for adjusting the at least one of the area or the position of the displayed image on at least one of the display or the external surface.

17. The method of claim 16, further comprising:

displaying the image on the external surface according to a default setting value.

18. The method of claim 17, further comprising:

receiving an input via an input unit of the mobile terminal;

adjusting a setting value by switching from the default setting value to one of a plurality of predefined setting values responsive to the input; and

displaying the image on the external surface according to the adjusted setting value.

19. The method of claim 18, wherein the plurality of predefined setting values comprise a ratio of the image.

20. A method for displaying an image on an external screen via a mobile terminal comprising a projector module and a wireless communication unit, the method comprising:

communicating with the external screen via the wireless communication unit;

transmitting the image and a control signal to the external screen;

adjusting at least one of an area or a position of the displayed image responsive to the control signal; and

displaying the image on the external screen according to the adjusted at least one of the area or the position.
