Why are the LED lights on the camera flickering and how to fix it?

have you ever seen led light twinkling on you camera As if it’s quickly turning on and off at regular intervals, but everything looks normal when viewed naked eyes, If you are, then there is no need to worry as it is quite normal for this to happen. And this becomes quite obvious because the frames per second and power frequency of the recording do not match, and this is why the LED lights flicker when you record. This phenomenon is known as the ‘strobe effect’.

But why don’t LED lights twinkle when we see with our own eyes? This is because the flickering happens very quickly, which means that the power frequency changes in very short intervals, leaving the flicker unnoticeable. human eyes.

Let us go a little deeper to understand this phenomenon better. So, let’s work on the LEDs alternating current AC, and one cycle, i.e. 1 Hz, occurs when one electron moves in and out, and the bulb is turned off twice. Therefore, alternating current typically operates at 50Hz across the globe (60Hz in the US), meaning an LED bulb is turning off and on at about 100 to 120 times. And it is so fast that humans cannot see it with their naked eyes. However, the camera clicks a picture of the light turning on and off during the cycle, thus causing the light to flicker on the camera.
How to stop the LED’s flickering on the camera
Flicker is annoying, and most of us want to get rid of it while recording videos. First, you can try adjusting the shutter speed in multiples of 50 or 60, i.e., 1/60, 1/120, etc. You can also try turning down the brightness of the light source or moving away from the source until the flickering time. stops. There is no permanent solution to this, but you can try playing with your camera or light source to reduce the flicker as much as possible.

Here’s How You Can Change the FPS on a Webcam


Open Settings, then click System.

To check if the flicker is reduced, open the Camera app.


If not, open Display Settings.
