Abstract

Provided herein is a control method of an electronic device. A gesture is detecting and a plurality of images of a user are photographed, if the gesture substantially corresponds to a predetermined gesture. A predetermined function is performed, if the change detected in the images is less than a predetermined threshold during a predetermined time period.

Claims

1. A control method of an electronic device, comprising:

detecting a gesture;

photographing a plurality of images of a user, when the gesture substantially corresponds to a predetermined gesture;

detecting whether a change has occurred in the images of the user during a predetermined time period; and

performing a predetermined function, when the change detected in the images is less than a predetermined threshold during the predetermined time period.

2. The control method of claim 1, wherein performing the predetermined function comprises turning on a screen of the electronic device.

3. The control method of claim 1, wherein performing the predetermined function comprises:

determining whether an application is being executed in a second electronic device; and

when the application is being executed in the second electronic device, displaying information corresponding to the application being executed in the second electronic device.

4. The control method of claim 1, wherein performing the predetermined function comprises changing from an off mode to a call mode.

5. The control method of claim 1, wherein performing the predetermined function comprises changing from an off mode to a message reception mode.

6. The control method of claim 1, wherein performing the predetermined function comprises changing from an off mode to a music play mode.

7. The control method of claim 1, wherein performing the predetermined function comprises changing from an off mode to an exercise mode.

8. An electronic device comprising:

a camera unit;

a sensor unit to detect a gesture; and

a controller to;

detect whether the gesture substantially corresponds to a predetermined gesture;

photograph a plurality of images of a user with the camera unit, when the gesture substantially corresponds to the predetermined gesture;

detect whether a change occurs in the images during a predetermined time period; and

perform a predetermined function, when the change detected in the images is less than a predetermined threshold during the predetermined time period.

9. The electronic device of claim 8, wherein the predetermined function comprises turning on a screen of the electronic device.

10. The electronic device of claim 8, further comprising:

a communication unit to communicate with a second electronic device; and

a display unit to;

determine whether an application is being executed in the second electronic device; and

display information corresponding to the application being executed in the second electronic device, when the application is being executed in the second electronic device and the change detected in the images is less than the predetermined threshold during the predetermined time period.

11. The electronic device of claim 8, wherein the controller to change from an off mode to a call mode.

12. The electronic device of claim 8, wherein the controller to change from an off mode to a message reception mode.

13. The electronic device of claim 8, wherein the controller to change from an off mode to a music play mode.

14. The electronic device of claim 8, wherein the controller to change from an off mode to an exercise mode.

15. A non-transitory computer-readable medium having instructions therein which upon execution instructs at least one processor to:

detecting a gesture;

photographing a plurality of images of a user, when the gesture substantially corresponds to a predetermined gesture;

detecting whether a change has occurred in the images of the user during a predetermined time period; and

performing a predetermined function, when the change detected in the images is less than a predetermined threshold during the predetermined time period.
