ABSTRACT:
A color television camera including a selectively removable infrared (IR) rejection filter and controllable weighting luminance signal matrixing circuitry features increased low-light sensitity. During low-light conditions, the infrared rejection filter is removed from the optical path of the camera, permitting infrared light to pass to the camera's imaging means; the weighting of the controllable weighting luminance signal matrixing circuitry is altered to provide a more accurate visual representation; and the color subcarrier signal is disabled so that the camera produces only a black-and-white signal.
