发明名称 Stroboscopic controller
摘要 A stroboscopic controller for illuminating a photographed object by discharging a charge stored to a main capacitor through a light emitting tube has a voltage measuring device for measuring a charging voltage of the main capacitor before light emission; a light quantity calculator for calculating a quantity of light required to illuminate the photographed object; a voltage calculator for calculating a voltage of the main capacitor at a stopping time of the light emission from the charging voltage measured by the voltage measuring device and the quantity of light calculated by the light quantity calculator; a time calculator for calculating a stroboscopic light emitting time for which the voltage of the main capacitor is changed by the stroboscopic light emission from the charging voltage before the light emission to the voltage at the stopping time of the light emission; and a light emission control device for controlling a light emitting operation and a stopping operation thereof with respect to the light emitting tube based on the stroboscopic light emitting time calculated by the time calculator.
