Abstract

A mobile terminal which includes a touch-screen display method thereof are provided. The mobile terminal includes a touch-screen display; a camera configured to capture image data; a sensing unit located in a corresponding area of the camera; and a controller configured to: receive a first touch gesture in the corresponding area of the camera, turn on the camera in response to the received first touch gesture and display a preview image on the touch-screen display, receive a second touch gestures in the corresponding area of the camera, said first touch gesture being different than the second touch gesture, and capture the image data in response to the second touch gesture, wherein the camera and the sensing unit are mounted on an area of the mobile terminal that excludes the touch-screen display.

Claims

1. A mobile terminal, comprising:

a touch-screen display;

a camera configured to capture image data;

a sensing unit located in a corresponding area of the camera; and

a controller configured to;

receive a first touch gesture in the corresponding area of the camera,

turn on the camera in response to the received first touch gesture and display a preview image on the touch-screen display,

receive a second touch gestures in the corresponding area of the camera, said first touch gesture being different than the second touch gesture, and

capture the image data in response to the second touch gesture,

wherein the camera and the sensing unit are mounted on an area of the mobile terminal that excludes the touch-screen display.

2. The mobile terminal of claim 1, wherein the first touch gestures includes at least one of a contact touch and a proximity touch.

3. The mobile terminal of claim 1, wherein the second touch gestures includes at least one of a contact touch and drag gesture and a proximity touch and drag gesture.

4. The mobile terminal of claim 1, wherein the controller is further configured to perform a zooming function of the camera in response to a third touch gesture.

5. The mobile terminal of claim 4, wherein the second touch gestures includes at least one of a vertical contact touch and drag gesture and a vertical proximity touch and drag gesture and the third touch gesture includes at least one of a horizontal contact touch and drag gesture and a horizontal proximity touch and drag gesture.

6. The mobile terminal of claim 4, wherein the controller is further configured to perform a zoom-in function in response to the third touch gesture including at least one of a contact touch and drag gesture and a proximity touch and drag gesture from left to right and to perform a zoom-out function in response to the third touch gesture including at least one of a contact touch and drag gesture and a proximity touch and drag gesture from right to left.

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

a light emitting element surrounding the camera,

wherein the controller is further configured to control the light emitting element to emit light to indicate an amount of the zooming function being performed.

8. The mobile terminal of claim 7, wherein the controller is further configured to control the light emitting element to increase an amount of light emitted as the zooming function increases and to decrease the amount of light as the zooming function decreases.

9. The mobile terminal of claim 8, wherein the light emitting elements has a ring shape surrounding the camera.

10. The mobile terminal of claim 1, wherein the camera is located on a back surface of the mobile terminal.

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

receiving, via a sensing unit located in a corresponding area of a camera of the mobile terminal, a first touch gesture in the corresponding;

turning on the camera, via a controller of the mobile terminal, in response to the received first touch gesture and displaying a preview image on the touch-screen display;

receiving, via the controller, a second touch gestures in the corresponding area of the camera, said first touch gesture being different than the second touch gesture; and

capturing, via the controller, image data included in the preview image in response to the second touch gesture,

wherein the camera and the sensing unit are mounted on an area of the mobile terminal that excludes the touch-screen display.

12. The method of claim 11, wherein the first touch gestures includes at least one of a contact touch and a proximity touch.

13. The method of claim 11, wherein the second touch gestures includes at least one of a contact touch and drag gesture and a proximity touch and drag gesture.

14. The method of claim 11, further comprising:

performing a zooming function of the camera in response to a third touch gesture.

15. The method of claim 14, wherein the second touch gestures includes at least one of a vertical contact touch and drag gesture and a vertical proximity touch and drag gesture and the third touch gesture includes at least one of a horizontal contact touch and drag gesture and a horizontal proximity touch and drag gesture.

16. The method of claim 14, further comprising:

performing a zoom-in function in response to the third touch gesture including at least one of a contact touch and drag gesture and a proximity touch and drag gesture from left to right; and

performing a zoom-out function in response to the third touch gesture including at least one of a contact touch and drag gesture and a proximity touch and drag gesture from right to left.

17. The method of claim 14, further comprising:

controlling a light emitting element surrounding the camera to emit light to indicate an amount of the zooming function being performed.

18. The method of claim 17, further comprising:

controlling the light emitting element to increase an amount of light emitted as the zooming function increases and to decrease the amount of light as the zooming function decreases.

19. The method of claim 18, wherein the light emitting elements has a ring shape surrounding the camera.

20. The method of claim 11, wherein the camera is located on a back surface of the mobile terminal.
