Abstract

PURPOSE: To prevent hand blur and make possible correct flash photography by setting shutter second time to the flash photography mode after the flash emittable state.
CONSTITUTION: A trigger circuit L is put in a trigger preparation state when a flash emittable state is reached upon completion of charging of the main capacitor Cm of a flashing device F and the shutter second changeover signal is transmitted to the camera C when the triggerable state is reached upon completion of trigger preparation by the trigger circuit L, so that the shutter second time is changed over to the second time for flash photography. As a resulot, the shutter second time is prevented from becoming hand blur second time by being affected by luminance, etc. at the time of flash photography and correct flash photography may be performed.
