LED Flicker
Another common cause of webcam flickering is LED flicker. Some webcams use LEDs to illuminate the scene, but these LEDs can flicker due to various reasons, including:
- AC Hum: The LED flicker can be caused by AC hum, which is a phenomenon where the LED’s brightness oscillates at a frequency of 60 Hz or 50 Hz, depending on the region’s power grid frequency.
- PWM (Pulse Width Modulation): Some LEDs use PWM to control their brightness. PWM can cause the LED to flicker, especially if the PWM frequency is low.
Power Supply Issues
Power supply issues can also cause webcam flickering. A faulty or unstable power supply can cause the webcam’s components to malfunction, leading to flickering.
Electrical Interference
Electrical interference from nearby devices or cables can also cause webcam flickering. This interference can disrupt the webcam’s signals, leading to an unstable video feed.
Troubleshooting Webcam Flickering
Now that we’ve discussed the causes of webcam flickering, let’s move on to troubleshooting tips to help you resolve the issue:
Adjust the Webcam Settings
Try adjusting the webcam settings to see if it resolves the flickering issue. Check the webcam’s settings for options like brightness, contrast, and exposure, and adjust them to optimal levels.
