Abstract

The present invention relates to a mobile terminal and a control method thereof. The mobile terminal according to the present invention comprises: a camera; a wireless communication unit for communicating with an external mobile photographing device; a display unit for outputting a preview image captured by the camera and detecting a touch input for designating a photographing region to be photographed by the mobile photographing device; and a control unit for controlling the wireless communication unit such that photographing guide information calculated on the basis of the photographing region is transmitted to the mobile photographing device on the basis of applying the touch input for designating the photographing region to the preview image and a preview image captured by the mobile photographing device according to the photographing guide information is received, and controlling the display unit such that the preview image captured by the mobile photographing device is outputted.

Claims

1. A mobile terminal, comprising:

a camera;

a wireless communication unit configured to perform communication with an external mobile photographing device;

a display unit configured to output a preview image captured by the camera and detect a touch input for designating a capturing area to be captured by the mobile photographing device; and

a controller configured to control, in response to the touch input for designating the capturing area being applied to the preview image, the wireless communication unit such that capturing guide information calculated based on the capturing area is transmitted to the mobile photographing device and a preview image captured by the mobile photographing device according to the capturing guide information is received, and control the display unit to output the preview image captured by the mobile photographing device.

2. The terminal of claim 1, wherein the controller calculates the capturing guide information based on the capturing area, in response to a multi-touch input for designating the capturing area being applied to the preview image captured by the camera.

3. The terminal of claim 2, wherein the controller sets the capturing area in a preset manner based on a multi-touch point to which the multi-touch input has been applied.

4. The terminal of claim 1, wherein the controller calculates the capturing guide information based on the capturing area, in response to a pinch-in or pinch-out input for designating the capturing area being applied to the preview image captured by the camera.

5. The terminal of claim 4, wherein the controller sets the capturing area to include the preview image based on a degree of the pinch-in input applied the preview image.

6. The terminal of claim 4, wherein the controller sets the capturing area to be included in the preview image based on a degree of the pinch-out input applied to the preview image.

7. The terminal of claim 1, wherein the controller calculates the capturing guide information based on a capturing altitude of the mobile photographing device, in response to a user input for designating the capturing altitude being applied.

8. The terminal of claim 1, wherein the controller calculates the capturing guide information based on a capturing direction, in response to a user input for designating the capturing direction of the mobile photographing device being applied.

9. The terminal of claim 1, wherein the controller controls the display unit to output both of the preview image captured by the camera and the preview image captured by the mobile photographing device according to the capturing guide information.

10. The terminal of claim 9, wherein the controller changes a capturing setting value for at least one of the preview image captured by the camera and the preview image captured by the mobile photographing device, in response to a preset touch input being applied.

11. A method for controlling a mobile terminal, the method comprising:

outputting a preview image captured by a camera on a display unit;

transmitting capturing guide information calculated based on a capturing area, which is to be captured by an external mobile photographing device, to a mobile photographing device, in response to a touch input for designating the capturing area being applied to the preview image; and

receiving a preview image captured by the mobile photographing device according to the capturing guide information and outputting the preview image on the display unit.

12. The method of claim 11, further comprising calculating the capturing guide information based on the capturing area, in response to a multi-touch input for designating the capturing area being applied to the preview image captured by the camera.

13. The method of claim 12, further comprising setting the capturing area in a preset manner based on a multi-touch point to which the multi-touch input has been applied.

14. The method of claim 11, further comprising calculating the capturing guide information based on the capturing area, in response to a pinch-in or pinch-out input for designating the capturing area being applied to the preview image captured by the camera.

15. The method of claim 14, further comprising setting the capturing area to include the preview image based on a degree of the pinch-in input applied to the preview image.

16. The method of claim 14, further comprising setting the capturing area to be included in the preview image based on a degree of the pinch-out input applied to the preview image.

17. The method of claim 11, further comprising calculating the capturing guide information based on a capturing altitude of the mobile photographing device, in response to a user input for designating the capturing altitude being applied.

18. The method of claim 11, further comprising calculating the capturing guide information based on a capturing direction of the mobile photographing device, in response to a user input for designating the capturing direction being applied.

19. The method of claim 11, further comprising outputting both of the preview image captured by the camera and the preview image captured by the mobile photographing device according to the capturing guide information.

20. The method of claim 19, further comprising changing a capturing setting value for at least one of the preview image captured by the camera and the preview image captured by the mobile photographing device according to the capturing guide information, in response to a preset touch input being applied.
