Abstract: PURPOSE:To set the photometric circuit of a camera to a stable condition at the time of transient abnormal output, by sending out a discriminated output when the output of the photometric circuit exceeds an output range corresponding to a previously set photometric range and making a bias current to flow to a photoelectric transducing element. CONSTITUTION:When a voltage exceeding a prescribed output range is produced in the photometric output Vo of a photometric circuit 10 due to an abnormal voltage component at the time of making power supply or the trigger noise component of an electric flash, in other words, when the residual electrostatic capacity of a photoelectric transducing element is charged with the abnormal voltage component or trigger noise component, the photometric output Vo of the moment is detected at a comparator circuit 20 and a decision output So is produced. Then a bias circuit 30 is actuated and the charged electric charge of the photoelectric transducing element of the photometric circuit 10 is discharged by a bias current sent from the bias circuit 30. As the electric charge is discharged, the photometric output Vo falls to the prescribed output range and the decision output So is not produced. Therefore, supply of the bias current to the photometric circuit 10 is cut off and the photometric output Vo becomes one which accurately corresponds to the light of an object received by the photoelectric transducing element.
