  • Patent number: 5898459
    Abstract: A multi-camera programmable pan-and-tilt apparatus comprising a base and a camera mechanism having a first camera and a second camera, with the second camera including a zoom mechanism for varying the zoom magnification of the second camera. The apparatus further has a pan-and-tilt mechanism for moving the cameras with respect to the base, and a video switch receiving the video outputs of the cameras and selecting one for view. The first camera is viewed while the camera mechanism is moved from one scene to another and the second camera is viewed while the camera mechanism is not moving and is paused for observation of a scene. A programmable controller controls the camera mechanism and the pan-and-tilt mechanism, and, while the camera mechanism is moving from one scene to another and the output of the first camera is being viewed, causes the zoom magnification and focus of the second camera to become set to the desired zoom magnification and focus for the next scene position.
