A method of authenticating whether a capture image is a real face of a driver in a vehicle includes first capturing an image of a driver's face with a light being turned on in a first image and with a light being turned off in a second image, respectively. Subsequent, a difference image is extracted between the first image data captured with the light being turned on and a second image data captured with the light being turned off. Then a boundary line is extracted from the difference image and a determination is made whether the boundary line is a curve or not. If the boundary line is determined to be a curve, the captured image is determined by a control unit to be the real face of the driver. |
