Abstract

PURPOSE:To control light emission of each stroboscope in accordance with a prescribed light quantity value set in advance, by making the other stroboscope emit a light beam when one stroboscope has stopped its light emission. CONSTITUTION:The ratio of the quantity of light emission of stroboscopes A, B is set suitably by operating a light quantity ratio variable changeover switch 15. In this state, when the shutter is fully opened, a light emission signal FA is outputted from a terminal 48, and the stroboscope A emits a light beam. When the quantity of light emission of this stroboscope A reaches the quantity of light of the set ratio, a light emission stop signal TA is outputted from a terminal 22, and the stroboscope A stops its light emission. At the same time, a light emission signal FB is outputted from a terminal 31, and the stroboscope B emits a light beam. In this way, since plural stroboscopes emit a light beam individually in order, light emission of each stroboscope can be controlled in accordance with a prescribed light quantity value set in advance.
