| 20110134251 | POWER CONTROL METHOD OF GESTURE RECOGNITION DEVICE BY DETECTING PRESENCE OF USER - 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. | 06-09-2011 |
| 20110157009 | DISPLAY DEVICE AND CONTROL METHOD THEREOF - A display device and a control method thereof are provided. The display device comprises a camera obtaining an image including a gesture of a user and a controller extracting the image of the gesture from the obtained image and executing a function mapped to the extracted gesture when the range of the gesture exceeds a threshold corresponding to the user. The method of controlling the display device executes functions respectively corresponding to specific gestures of users when the gestures exceed thresholds respectively corresponding to the users to operate the display device in a manner most suitable for the range of the gesture of each user. | 06-30-2011 |
| 20110163954 | DISPLAY DEVICE AND CONTROL METHOD THEREOF - A display device and a control method thereof are provided. The display device includes a camera obtaining an image and a controller obtaining the direction of a user included in the obtained image and correcting the image such that the direction of the user is synchronized with the photographing direction of the camera. Even when the direction of the user does not correspond to the photographing direction of the camera, an image of the user can be corrected to correctly recognize a user's gesture. | 07-07-2011 |
