The signal capture module 13 can be further connected to the power conversion module 3, and The power conversion module 3 is connected to an AC power source 4.

An adjustment synchronization module 14 is connected to the signal acquisition module 13 to receive the vertical signal, and then synchronizes the operation timing of the illumination device 11 with the vertical signal, and uses this as an output signal.

The clock control module 15 is connected to the constant current control switch 12 and the adjustment synchronization module 14, and can receive the output signal of the adjustment synchronization module 14, and adjust the working time of the illumination device 11 to be between 0.05 milliseconds and 0.99 milliseconds, and The constant current control type switch 12 is controlled in accordance with the operating time (lighting time) of the light-emitting device 11, so that the light-emitting device 11 can emit the white light that assists the illumination of the electronic camera 2.
