1. A gesture device comprising:

  • an infrared light source configured to irradiate infrared light;

    a camera configured to capture an image in a locked state mode for receiving an activation gesture and in an idle state mode for receiving a plurality of driving gestures;

    a gesture processing unit configured to extract a gesture from the image captured via the camera while in the locked state mode and the idle state mode; and

    a control unit configured to;

    capture a first image, via the camera, while in the locked state mode, and extract brightness information from the first image, and drive the infrared light source to irradiate the infrared light when the brightness information is less than a threshold value,capture a second image, via the camera, while in the locked state mode in which the infrared light is irradiated by the infrared light source,obtain a first gesture extracted from the second image while in the locked state mode,determine whether the first gesture is the activation gesture while in the locked state mode,in response to the first gesture being different than the activation gesture while in the locked state mode, ignore the first gesture,in response to the first gesture being the activation gesture while in the locked state mode, change the locked state mode to the idle state mode,capture a third image, via the camera, while in the idle state mode after the changing the locked state mode to the idle state mode,obtain a second gesture extracted from the third image while in the idle state mode,determine whether the second gesture is a driving gesture,in response to the second gesture being a first driving gesture among the plurality of driving gestures while in the idle state mode, execute a first function corresponding to the first driving gesture, andin response to the second gesture, which represents the activation gesture in the locked state mode, representing a second driving gesture among the plurality of driving gestures while in the idle state mode, execute a second function corresponding to the second driving gesture,wherein the second function is different than a function of changing the locked state mode to the idle state mode, andwherein the activation gesture and the second driving gesture are a same gesture that corresponds to different functions in the locked state mode and the idle state mode.
