Experience with a broadcast-type four vidicon color film chain has indicated that to maintain good performance, frequent and skilled maintenance is required. A simplified color slide TV camera system has been developed using the flying-spot scanner principle. A recently-developed phosphor for color flying-spot tubes contributed substantially to the picture quality and signal-to-noise ratio improvement over previous color flying-spot cameras. A minimum number of operating adjustments is needed because of the inherent simplicity of a flying-spot camera and because the camera, encoder/matrix and sync generator incorporate circuits which inherently require minimum adjustment. Animation can be provided with polarized slides, if desired. The polarization system, which provides animation, has been designed to minimize unwanted color modulation. Automatic cuing of the slide projector advance mechanism, and an audio channel, can be incorporated.
