ABSTRACT:
A camera includes producing means for detecting the state of the luminance of the object field and producing a luminance information signal conforming to the detected state of the luminance of the object field, control means for calculating the exposure value for exposure of a film on the basis of the luminance information signal and performing the exposing operation of the film, setting means for setting a comparative level on the basis of the luminance information signal, flash emitting means for emitting flash toward the object field in response to the start of the exposing operation by the control means, means for calculating the integrated value of at least a part of the light from the object field at any time in response to the start of the exposing operation by the control means, and stop means for detecting that the integrated value and the comparative level have assumed a predetermined relation and stopping the flash emitting operation of the flash emitting means.
