  • Patent number: 5329325
    Abstract: The present invention is directed to a multiple camera system which captures a photo image on film and captures and stores an electronic image on a magnetic recording media. The system has two operating states. In the "compose" or "view" state the electronic image channel is operated at a first gain setting, color temperature and F-stop to provide a real time moving image on a monitor. In the capture state the electronic gain, color temperature, and F-stop of the electronic camera are altered to collect or capture an electronic image during strobe illumination. The system utilizes a pair of dedicated zoom lenses, which are mechanically corrected for parallax error and the focal length of the two lenses are matched and linked together so that their focal lengths may be altered simultaneously by the operator.
