ABSTRACT:
A television camera-recorder combination includes an imager which forms a signal representative of the image during an integration interval. The integration interval is followed by a pull-down interval during which the integrated signal is transferred out of the photoresponsive region. Streaking of an image displayed from the signal results from light falling on the photoresponsive region during the pull-down interval. A mechanical shutter periodically prevents light from falling upon the photoresponsive region of the imager. The shutter is synchronized with the pull-down interval. The synchronization and drive arrangement of the video recorder portion is mechanically coupled to the shutter to provide a common drive. In another embodiment, a color wheel associated with the viewfinder of the camera is mechanically coupled to the video recorder drive arrangement for common mechanical drive.
