<p>A portion of invisible light (136), as shown in Figure 1, may be reflected by the reflector (120), which is attached to the object (110), to reach a camera (140). The camera (140) is sensitive to both visible light and invisible light (134), which enters the camera through lens (144). Invisible light is emitted (130) onto the object (110), and an object (110) is tracked by processes performed by the camera (140) by moving the field of view of the camera, so that the object is centered within the field of view (160). The camera may also zoom the field of view to a desired magnification level.</p> |
