摘要 PURPOSE:To simplify a control method and to control exposure at the time of daylight synchro photographing to be at an appropriate level by providing a stop value information output means which changes in accordance with the brightness of an object. CONSTITUTION:1st stop value information corresponding to the maximum aperture diameter of a shutter in accordance with object brightness information is read out from a ROM and stored in a data RAM inside a CPU 1. Continuously, 2nd stop value information corresponding to the light emitting timing of an electronic flash device 5 in accordance with object distance information is read out from the ROM and stored in the data RAM inside the CPU 1. By comparing and arithmetically operating two pieces of stop value information stored in the RAM in the CPU 1, data corresponding to the information on the smaller stop value is stored in the RAM as controlled stop value data. Therefore, the electronic flash device 5 is triggered in timing corresponding to the smaller stop value information.
