The utility model relates to a makeup flashing control device of LED in synchronous action with the video camera, comprises a light source control processor, a synchronous timer, an LED flasher, a crystal oscillator clock and a video camera. The light source control processor is connected with the synchronous timer and the video camera and the synchronous timer is connected with the LED flasher. The crystal oscillator clock is connected with the synchronous timer. Compared with the prior art, the utility model provides a flashing source which is flicker free and synchronous with the shutter of the video camera. The utility model synchronizes the flashing pulse of the LED light source and the shutter and supplies light source with high-speed flashing, so can reduce the consumption of the electric energy and prolong the LED life by reducing the working temperature of the LED on the prime of ensuring the light. The utility model can also reduce the brightness of the light source while keeping the imaging quality, which avoids that the light glares the eyes, so has an advantage of taking picture unaffectedly.收起
