    Patent number: 5243432
    Abstract: An automatic shutter speed control circuit for a video camera that includes a pulse generating circuit, a pulse processing circuit and a signal outputting circuit. The pulse generating circuit includes a signal detecting circuit, a first switch, a shaping circuit, a switching control circuit, a second switch, a pulse generating circuit and a combining circuit. The pulse processing circuit includes a signal processing circuit, an error correcting circuit and a third switch. The signal outputting circuit includes a fourth switch and a control signal generating circuit. The pulse generating circuit generates a single pulse train per field representative of the object's speed. The output circuit generates a control signal based on the pulse train to control shutter speed.
