1. A computing device controllable by a user'"'"'s gesture, the computing device comprising:
- a presence detector configured to detect a presence of the user within a predetermined area from a camera that is turned off;
a controller configured to;
control the presence detector,turn on the camera, when the presence of the user is detected,drive the camera in a low power mode to detect a first gesture of the user,drive the camera in a high power mode to detect a second gesture of the user, when the first gesture of the user is detected, andexecute a command corresponding to the second gesture of the user, when the second gesture of the user is detected,wherein the first gesture is an active gesture, the second gesture is one of all gestures, and the low power mode and the high power mode are selectively driven by controlling an illumination intensity of the camera; and
a display unit configured to display information indicating that the camera has entered into a mode for detecting the gesture of the user.

Abstract
Provided is a method which reduces the power consumption of a camera for detecting a user'"'"'s gesture, in a device that detects the user'"'"'s gesture and performs a command corresponding to the detected gesture. Moreover, provided is a method which turns off a camera or drives the camera in an ultra low power mode when there is no user input, and detects presence of a user to activate the camera.

1. A computing device controllable by a user'"'"'s gesture, the computing device comprising:
-
a presence detector configured to detect a presence of the user within a predetermined area from a camera that is turned off; a controller configured to; control the presence detector, turn on the camera, when the presence of the user is detected, drive the camera in a low power mode to detect a first gesture of the user, drive the camera in a high power mode to detect a second gesture of the user, when the first gesture of the user is detected, and execute a command corresponding to the second gesture of the user, when the second gesture of the user is detected, wherein the first gesture is an active gesture, the second gesture is one of all gestures, and the low power mode and the high power mode are selectively driven by controlling an illumination intensity of the camera; and a display unit configured to display information indicating that the camera has entered into a mode for detecting the gesture of the user. - View Dependent Claims (2, 3, 4, 5, 6, 7)

8. A computing device controllable by a user'"'"'s gesture, the computing device comprising:
-
a controller configured to control a camera so that the camera is turned on when a presence of the user is detected within a predetermined area, to drive the camera in a low power mode to detect a first gesture of the user, to switch the low power mode of the camera to a high power mode for detecting a second gesture of the user when the first gesture is detected, and to execute a command corresponding to the second gesture of the user when the second gesture of the user is detected, wherein the lower power mode and the high power mode are selectively driven by controlling an illumination intensity of the camera; and a display unit configured to display information indicating that the camera has entered into a mode for detecting the gesture of the user. - View Dependent Claims (9, 10, 11)

12. A method of controlling a computing device controllable by a user'"'"'s gesture, the method comprising:
-
detecting, by a presence detector of the computing device, a presence of the user within a predetermined area from a camera that is turned off; turning on the camera, when the presence of the user is detected; driving the camera in a low power mode to detect a first gesture of the user; driving the camera in a high power mode to detect a second gesture of the user, when the first gesture of the user is detected; and executing a command corresponding to the second gesture of the user, when the second gesture of the user is detected, wherein the first gesture is an active gesture, and the second gesture is one of all gestures, and wherein the low power mode and the high power mode are selectively driven by controlling an illumination intensity of the camera. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A method of controlling a computing device controllable by a user'"'"'s gesture, the method comprising:
-
turning on a camera when a presence of the user is detected within a predetermined area to operate the camera in a low power mode for detecting a first gesture of the user; switching the lower power mode of the camera to a high power mode for detecting a second gesture of the user, when the first gesture is detected; and executing a command corresponding to the second gesture of the user when the second gesture of the user is detected, wherein the low power mode and the high power mode are selectively driven by controlling an illumination intensity of the camera. - View Dependent Claims (20, 21, 22)
