PURPOSE:To make it possible to simply determine a state capable of obtaining proper exposure with good accuracy even when a shutter speed and a lens opening value were determined, by measuring light the containing a flash light component in a state separated into the quantity of steady light and that of flash light. CONSTITUTION:Photometric means C1, C2 measure light containing a flash light component in a state separated into the quantity of steady light and flash light. Shutter speed setting means SW3, SW4, SW13 set shutter speeds and a lens opening value setting means SW3, SW4, SW13 set lens opening values. Quantity of exposure for obtaining proper exposure is calculated from the each set shutter speed and each set lens opening value by an exposure quantity calculation means CPU. The quantity of deviation of the calculated quantity of exposure with the photometric quantity means by each of the photometric means C1, C2 is calculated by a deviation calculating means CPU. Then the ratio of the calculated quantity of exposure and the quantity of flash light measured by the means C1, C2 is calculated by a ratio calculating means CPU to be displayed on a display means LCD. By this method, the excess and deficiency of the quantity of flash light to proper exposure is displayed in terms of a ratio.
