发明名称 FLASH LIGHT CONTROL SYSTEM
摘要 PURPOSE:To provide a flash fight control system capable of obtaining an exposure suitable for a photographic scene under a camera by calculating an emitted light quantity, per a pulse and emitting light so as to consecutively output a high frequency pulse at the light quantity of the calculation, in the emission of flash light executed for a light exposure. CONSTITUTION:The emitted light quantity per a pulse is calculated from the total quantity of the flash light emitted during an exposing time, a control shutter speed in main light emission obtained based on output from a photometric circuit 3 and a light emission frequency previously set in the camera, the emitted light quantity per a pulse is monitored by a photodetector provided in a flashing device 9 and the start and completion of the emission of the light is controlled so that the emission of the light at a constant light quantity is executed.
