Abstract
PURPOSE:To make possible announcing of low luminance, correct luminance, uncharging and charging completion of main discharge capacitor and the ability drop of power source by controlling the operations of plural display circuits under the specified conditions. CONSTITUTION:When a normally open switch 5 is closed, a power source 2 is supplied to a voltage detecting circuit 4 and when the voltage value above the specified level is detected, it is supplied to a photo detecting circuit 6 through a control circuit 8 and power source switch 3. The circuit 6 performs detection of the subject luminance and supplies the corresponding signal output to the circuit 8. Controlling of display circuit 9, 10 is accomplished by the operation of the circuit 8. The circuit 9 is operated at the the luminance or at the uncharging of the main discharge capacitor of a strobe device 1 and the circuit 10 is operated at the correct luminance or at the charging completion of the main capacitor. When the ability of the power source 2 has dropped, the circuits 9, 10 are disabled.
