Abstract

PURPOSE:To at all times photograph low tube voltage and to obtain a high contrast cinematographic picture, by controlling a make-and-break mechanism of a lens diaphragm of a cinematographic equipment on the basis of the output which a comparator generaters when the tube voltage exceeds its set value. CONSTITUTION:When a photographic subject is large in thickness, the luminance of light image on an output fluorescent screen 8 decreases and a luminance level automatic control circuit 17 operates so as to rise tube voltage. As the tube voltage rises and an output of a potentiometer (PM) 35 becomes higher than the output of PM36 which sets up the maximum level of the tube voltage, an output of a comparator 37 inverts to 1 level and a motor driving circuit 38 operating, a diaphragm driving motor 16 becomes operationable. At the same time, a relay contact 24b of a normal luminance level setting device 24 closes and a diaphragm of a cinematographic equipment 13 operates so as to increase its opening. PM24C's voltage increasing and the setting device 24's output voltage decreasing, the tube voltage drops.
