Abstract

PURPOSE:To execute proper exposure by setting a proper guide number in a flash light emitting device and actuating it when the luminance of field is smaller than the lowest proper allowable luminance set by a set luminance arithmetic circuit. CONSTITUTION:When a set luminance signal 27 is larger than an object luminance signal 32 expressing the actual luminance of an object from a photometry device 31, an OR circuit 38 energizes the flash light emission circuit 34 so as to emit a flash light after outputting either a driving signal 20 from a control circuit 19 or an output signal 28 from a timer 26. A guide number arithmetic circuit 44 which works with the output 22 from a film sensitivity switching device 21 and the output 4 from a range finder 3 is provided in the titled camera, which is constituted so that the guide number to be set in the circuit 34 is computed to be given to the device 34, thereby always obtaining the proper exposure. When the set luminance signal 27 is smaller than the set lowest proper exposure allowable luminance, the guide number for the proper exposure is set in the circuit 34 so as to actuate the circuit 34.
