PURPOSE:To obtain an optimum brightness similar to an ordinary photographing by calculating a diaphragm value from the quantity of light data of a stroboscopic light emission stored in the quantity of light storing means and distance data measured by a distance measuring means. CONSTITUTION:A switch 17 for switching a diaphragm voltage for a general exposure and a diaphragm voltage for a stroboscopic exposure and outputting to a motor 3 for the diaphragm is changed over to a terminal (b) side. A test light emission from a stroboscope 12 is received in a light receiving part 13, the quantity of light data is stored in a microprocessor 15 and the distance data from an encoder for calculating the distance is fetched to the microprocessor 15 before a next stroboscopic light emission. The microprocessor 15 calculates the optimum diaphragm value based thereon, drives the motor 3 for the diaphragm through an amplifier 16 and the change over switch 17 to set the diaphragm 2 to an optimum state. Thereby, the stroboscope is light emitted to photograph an object, thereby, the video of the optimum brightness similar to the ordinary photographing can be obtained. |
