  • Patent number: 5959717
    Abstract: A combination film projector and video projector for showing a single composite motion picture, and a motion picture audience monitoring system. The video projector is used to provide image content for a video display subarea on the projected film image. Thus, all of the light output of the video projector is focused on a substantially smaller subarea of the screen. Uses of the combination of both a film projector and video projector include theft deterrence and special effects. Another aspect includes a motion picture audience monitoring system including a camera and/or microphone directed at the audience and coupled to an analysis system. The audience monitoring system can be used to obtain demographic information about the attending audience. The system can be used in conjunction with a pattern recognition system to determine such information.
