发明名称 EMISSION CONTROL SYSTEM OF ELECTRONIC FLASHING DEVICE
摘要 PURPOSE:To prevent unevenness of exposure from being caused during full open exposure and slit exposure by an electronic flashing device which repeatedly emits light at high speed. CONSTITUTION:A camera 500 having a CPU 10 which controls both a first blind controlling circuit 12 and a second blind controlling circuit 13 is combined with at least an electronic flashing device 600 which repeatedly emits light at high speed and, in the case of full open exposure whereby the second blind of a shutter starts to run after the first blind of the shutter is full open as the camera 500 is released, the electronic flashing device 600 starts emitting light when the first shutter blind of the camera is full open, and stops emitting light when the second shutter blind of the camera starts to shut off the exposure of the camera, whereas in the case of slit exposure whereby the second shutter blind starts to run before the first shutter blind of the camera is full open, the electronic flashing device 600 starts to repeat emission of light at high speed when the first shutter blind of the camera starts exposure, and stops emitting light when the second shutter blind of the camera completes exposure of the camera.
