The invention discloses a high-speed shooting flashlight enhancement device. The device comprises a flashlight lamp holder assembly, a casing, a function control panel, a synchronous triggering device, a time controller and a large-power capacitor charging and discharging controller, the function control panel is fixed at the outer side of the casing, the synchronous triggering device, the time controller and the large-power capacitor charging and discharging controller are connected successively and fixed at the inner side of the casing, and the flashlight lamp holder assembly is connected to the casing directly or via a middle cable. The flashlight enhancement device can reduce the exposure time of a single-frame picture of high-speed shooting to 0.1 microsecond and lower, a super-high speed camera can shoot 10 million of pictures per second, the pictures are clear enough to see by the human eyes, an object whose movement speed is greater than 5000m/s can be shot without virtual shadows, the total shooting time length can reach 0.1s, synchronization time between the high-speed movement object and illumination can be controlled within 100ns, the device is adapted to severe test environments as explosion and impact lamps, and the difficulty that shooting during super-high speed movement lacks light is overcome.
