Abstract

PURPOSE: To perform exactly the setting of conditions without being affected by the luminous and phosphor characteristics of multiplying tube by the procedure in which the brightness of the output image of camera multiplying tube is detected, and then the detected output signal is integrated only for a period relating to the opening of shutter for displaying.
CONSTITUTION: The brightness of the output image of the image tube II is detected by the photoelectric multiplying tube pH and then put in the integrator I consisting of the amplifier A1, the condenser C1, the condenser C1, the resistance R0, and the amplifier A2. The shutter opening and closing signal of the cinecamera CA is put in the comparator A3 with non-inversion terminal, and the transistor Tr for controlling charge and discharge, connected through the resistor R1 to the condenser C1 of the integral circuit I in parallel, is controlled by the output of the comparator A3. The display circuit K which directs the output value of the integrator I consists of the diode D to hold the output peak value of the integrator I, the peak value- holding circuit H composed of the condenser C2, and the indicator M to direct the output value of the circuit H. Thus, the setting of conditions can be exactly performed.
