Abstract
PURPOSE: To make it possible to set only the exposure time proper for stroboscopic photography by making a manual setting of the exposure time possible in addition to an automatic exposure time control, and detecting when a stroboscopic device is allowed to emit light.
CONSTITUTION: Manual set exposure time signal is inputted into exposure time signal producing circuit 6 to make it possible to provide manual setting for the exposure time, and concurrently, detecting signal for the state of light emission ability of stroboscopic circuit 14 fixed on the camera together with output signal of exposure time signal producing circuit are inputted. Thus, it has control circuit connected so that the output signal which can set only the exposure time suitalbe for stroboscopic photography when the stroboscopic circuit becomes the point when it is possible to emit light may output into the comparator. And in the state where the stroboscopic device is fixed, even when the shutter is depressed, but the light emission state does not reach. Thus, when the output of inverter 24 is at H lelvel, either automatic control or manual set exposure time can be selectively set. In addition, when the stroboscopic device is in the light emission state, AND circuit 25aW25e are all inoperative, and OR circuit 25 s t only is operated to be able to photograph with the proper exposure time.
