  • Patent number: 4257063
    Abstract: A television system and method are disclosed for monitoring and indicating changes in a scene from which electromagnetic radiation, such as visible light, emanates. A television system including a television camera scans the scene in known raster fashion in a series of image frames, producing an amplitude modulated video signal describing the energy intensity distribution of the scene. Clocking and gating circuitry triggered in synchronism with television camera synchronization signals defines a set of predetermined discrete spaced locations of the raster during each image frame and samples video signal amplitude at each of the defined locations. The same discrete locations are sampled during each frame. Video selection circuitry, during a succession of sampling periods, inputs in real time a representation of each video amplitude sample to one of several storage channels of a multi-channel memory system including a multi-channel counter.
