An LED stroboscope device synchronized with a camera, which comprises: a power supply unit; a stroboscope unit which receives power from the power supply unit so as to charge the power for generating a flashing light, and then, outputs a flashing light generation signal for electric discharge of the charged power; a continuous light unit which receives the power from the power supply unit so as to output a continuous light generation signal for generating continuous light; a light emitting unit which individually receives the flashing light generation signal and the continuous light generation signal so as to generate the flashing light and the continuous light; and a control unit which receives the power from the power supply unit so as to individually control the stroboscope unit and the continuous light unit, thereby outputting the flashing light generation signal and the continuous light generation signal.
