ABSTRACT:
A diaphragm control apparatus for a lens of a CCTV camera having a diaphragm driver for opening or closing a diaphragm in accordance with a diaphragm control signal, includes a remote diaphragm controller which outputs a remote diaphragm control signal to set an optional diaphragm position, a diaphragm control signal setting device which sets a diaphragm control signal in accordance with the remote diaphragm control signal and which outputs the diaphragm control signal to the diaphragm driver to move the diaphragm to a diaphragm position corresponding to the diaphragm control signal, and a power source which supplies power to the diaphragm control signal setting device. The diaphragm control signal setting device is provided with a memory for storing the diaphragm control signal when the power supply is interrupted, so that the diaphragm control signal which has been set at the interruption of the power supply can be output when the power supply is carried out again.
