Why do LED lights flicker on the camera?

Stopping the stroboscopic effect itself is very unhelpful, however, the irritating stroboscopic effect is what we are trying to eliminate, and while eliminating the stroboscopic effect is an incredibly precise task, it is easily reduced by adjusting the frame rate and shutter speed.

Outside of the United States, alternating current is supplied at 50 hertz, which means that the current changes between on and off 50 times in 1 second. By adjusting camera parameters, namely shutter speed and frame rate in multiples or fractions of 50, the strobe effect can be significantly reduced.

Some LED lights are adjusted by the driver, and the flicker frequency is controlled by adjusting their on-off period. If the flicker rate is adjusted to exceed the camera frame rate, the stroboscopic effect can be effectively eliminated.
