ンカメラのセツトアツプ付加回路。 A mixing amplifier that loads a setup signal onto a video signal has a current conversion circuit that converts the setup signal into a current, and the value of the input resistance to the mixing amplifier connected to the current conversion circuit changes the input video signal voltage to the mixing amplifier. A setup additional circuit for a television camera, characterized in that the current value is equal to the value divided by the output current value of the current conversion circuit.
