Abstract

A mobile terminal including a wireless communication unit configured to provide wireless communication; a camera; a touchscreen; a memory; and a controller configured to receive a first user gesture indicating a readiness for capturing an image through the camera, receive a second user gesture after receiving the first user gesture for indicating the camera to capture the image, and capture the image after a predetermined time period from receiving the second user gesture.

Claims

1. A mobile terminal comprising:

a wireless communication unit configured to provide wireless communication;

a camera;

a touch screen;

a memory; and

a controller configured to;

receive a first user gesture indicating a readiness for capturing an image through the camera,

receive a second user gesture after receiving the first user gesture for indicating the camera to capture the image, and

capture the image after a predetermined time period from receiving the second user gesture.

2. The mobile terminal of claim 1, wherein the first user gesture is a still hand gesture and the second user gesture is a continuous hand gesture from the still hand gesture.

3. The mobile terminal of claim 2, wherein the still hand gesture is an open hand gesture and the continuous hand gesture is a closing hand gesture.

4. The mobile terminal of claim 1, wherein the controller is further configured to:

display a gesture indicator on the touch screen indicating the first user gesture is recognized by the controller.

5. The mobile terminal of claim 1, wherein the controller is further configured to:

display control buttons on the touch screen for controlling options of the camera,

receive a command to remove the displayed control buttons, and

stop displaying the control buttons when receiving the command.

6. The mobile terminal of claim 1, wherein the controller is further configured to:

display a countdown indicator on the touch screen counting down the predetermined time period until the image is captured.

7. The mobile terminal of claim 1, wherein the controller is further configured to:

sense a first position of the mobile terminal when receiving the first and second user gestures, and

display a preview image of the captured image when the mobile terminal is moved to a second position different than the first position.

8. The mobile terminal of claim 7, wherein the controller is further configured to:

capture another image when the mobile terminal is moved back to the first position from the second position without having to receive the first and second user gestures.

9. The mobile terminal of claim 1, wherein the controller is further configured to:

sense a first position of the mobile terminal when receiving the first and second user gestures, and

capture another image when the mobile terminal is maintained in the first position after capturing the image.

10. The mobile terminal of claim 1, wherein the controller is further configured to:

receive a third user gesture, and

perform an additional camera operation based on the received third user gesture.

11. The mobile terminal of claim 10, wherein the third user gesture includes a number of fingers being extended, and the additional camera operation includes capturing a number of images corresponding to the number of fingers extended in the third user gesture.

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

another camera on a back side of the mobile terminal opposite to the touch screen; and

a light emitting element mounted on the back side of the mobile terminal,

wherein the controller is further configured to;

control the light emitting element to emit a first light indicating the first user gesture is recognized, and

control the light emitting element to emit a second light indicating the first user gesture is not recognized.

13. The mobile terminal of claim 1, wherein the first user gesture is a still finger gesture and the second user gesture is a continuous finger gesture from the still finger gesture.

14. The mobile terminal of claim 13, wherein the still finger gesture is an open finger gesture and the continuous finger gesture is a closing finger gesture.

18. The method of claim 13, further comprising:

displaying a gesture indicator on a touch screen indicating the first user gesture is recognized by the controller.

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

receiving, via a controller of the mobile terminal, a first user gesture indicating a readiness for capturing an image through a camera of the mobile terminal;

receiving, via the controller, a second user gesture after receiving the first user gesture for indicating the camera to capture the image; and

capturing, via the camera, the image after a predetermined time period from receiving the second user gesture.

16. The method of claim 15, wherein the first user gesture is a still hand gesture and the second user gesture is a continuous hand gesture from the still hand gesture.

17. The method of claim 16, wherein the still hand gesture is an open hand gesture and the continuous hand gesture is a closing hand gesture.

19. The method of claim 15, further comprising:

displaying control buttons on a touch screen for controlling options of the camera;

receiving a command to remove the displayed control buttons; and

stopping display of the control buttons when receiving the command.

20. The method of claim 15, further comprising:

displaying a countdown indicator on the touch screen counting down the predetermined time period until the image is captured.
