Sensing apparatus for user terminal using camera, method for the same and controlling method for the same

A sensing device of a user terminal with a camera, the image analysis unit 110 to the camera analyzes the image parameters of the image sensing object; And a user with a camera which is characterized in that based on the image parameters analyzed by the image analysis unit 110 includes a touch determination unit 120 for determining a touch, and whether the intensity of the object to the user terminal the sensing device of the terminal is provided. According to the invention, it is possible to use a camera that is already installed in the user terminal without the addition or change of a separate hardware device to sense a touch pressure of the object for the user terminal, the rotation angle or the like. Accordingly, the function of the camera and not just as an imaging means of the external object, the operation of the various user terminals, close to control, it is possible to use, touch the camera is furthermore usually provided to the back of the touch screen by the user and any strength by the advantage that can be operated, the control terminal without occlusion problem of the touch screen.
