摘要： PROBLEM TO BE SOLVED: To provide a strobe light emitting unit capable of completely achieving a function for diffusing emitted light while suppressing power consumption in use to be low. SOLUTION: When a synchronizing signal is input from a camera 1, a control circuit 35 outputs a drive turn-on signal to a driver 34. When the drive turn-on signal is input, the driver 34 applies voltage to a liquid crystal optical element 2. When predetermined time elapses, the control circuit 35 outputs a drive turn-off signal to the driver 34. When the drive turn-off signal is input, the driver 34 gets in such a state that it does not apply the voltage to the liquid crystal optical element 2. The predetermined time is equivalent to the time when a discharge tube 31 is lit. A liquid crystal/cured material complex whose response time is shorter than 5ms is used as the liquid crystal optical element 2. COPYRIGHT: (C)2010,JPO&INPIT
