ABSTRACT:
In a power-saving stroboscopic device, a main capacitor is not completely discharged even in full light emission, so that a predetermined amount of charge can be left in a main capacitor, in order to save power in a stroboscopic circuit of the device. A light emission unit of the stroboscopic device can perform full light emission and flat emission based on a period of light emission time set by predetermined conditions. The stroboscopic device comprises a light emission control unit and a control unit for controlling a period of light emission time, so that a residual voltage in a main capacitor in the stroboscopic circuit is higher than a residual voltage after full light emission, in order to improve the charging efficiency after the full light emission.
