An increase in home work and video conferencing means that more people now regularly use webcams.A flashing webcam can't possibly ruin your life, but it can be incredibly frustrating.
Here's how to diagnose why your webcam is flickering and how to stop it from happening.
What is causing the webcam to flicker?
There can be several potential causes for the constant flickering of the webcam.One of the most likely reasons is a conflict between shutter speed and the lighting in the room.
While it may not look like it, lighting elements that use alternating current pulse extremely fast, producing what appears to be a constant brightness.If the frequency of these pulses, called oscillations per second, is synchronized with the shutter speed of the camera, image flickering occurs.This is a very simple explanation, but hopefully you get the point.
You can test this by turning off the lights.If the blinking stops at this point, you've found the cause.
Other potential causes include outdated drivers and incorrect settings in applications accessing the webcam.Using a low speed USB port can even cause it.
1. Change the frequency or shutter speed
Turning off the lights may not be practical, or even impossible, when using a webcam.Fortunately, there is usually another way to solve this problem.
1. If using the built-in webcam, open the Windows Camera application and tap the Settings icon.
2. Select Video Settings and change Flicker Reduction from 60Hz to 50Hz.
Some video chat/conferencing software will override this change with their own preset frequency settings.Most allow you to adjust the shutter speed or adjust the power frequency.For example, on Skype:
1. Open Skype Main Settings and tap Audio & Video.
2. Click Webcam Settings to open a new Properties window.
3. On the Video Proc Amp tab, change the PowerLine frequency from 60Hz to 50Hz.
4. Click Apply and check if the flickering problem has been fixed.
This method will also be necessary if using an external webcam, as the Windows Camera app's settings will not apply.The software that came with the webcam may also include frequency settings.
2. Update your system and webcam software
If you've eliminated shutter speed and lighting conflicts as potential causes of flickering, making sure all software is up to date is the next step.
Check for any pending Windows system updates.There may be a revised version of the camera app in a cumulative or quality update that will fix this.You should also check the optional updates section, as webcam software updates can sometimes be hidden there.
Install all available updates and restart your computer.You can then test the webcam to see if the flickering problem improves in any way.
3. Update the webcam driver
Next, check to see if the webcam's driver has been updated.Drivers are only tied to a specific device or component, making them less likely to be updated during a previous fix.
1. Open "Device Manager" and look for "Imaging Devices", "Cameras" or similar in the device list.
2. Right-click the webcam and click Update Driver in the Actions menu.If more than one webcam is listed, make sure you're updating the correct one.
3. Follow the on-screen instructions to scan for and install any available driver updates.
If you're using external webcam software, check for updates for this as well.It's unlikely that the webcam software is causing the flickering, but the update may include a way to stop it.
4. Test the USB connection (external webcam only)
If using an external USB webcam instead of the one built into your laptop or screen, the USB port could be the problem.The USB port you are using may be faulty or too slow.
Some webcams require a USB 3.0 connection, so make sure your webcam is connected to the correct USB port on your computer. The inside of a USB 3.0 port is usually blue.If you have more than one suitable USB port available, try placing your webcam in different ports.
5. Disable Low Light Compensation
Your webcam properties may include an option to enable low light compensation.This will automatically increase the brightness of the image if the ambient lighting is poor.Disabling this optional feature can prevent webcam flickering.
If this option is available, you'll find it in the settings or properties menu of the webcam software you installed when you set up the camera.
Your internal webcam may also have this feature, but availability varies by model of laptop.Most internal webcams, the type built into the top of a laptop screen, default to the Windows Camera app.
If there is no low light compensation option in the webcam software, please check it in the settings of the video chat application you are using.
6. ChangeWindows 11's power settings
In some cases, especially when using a battery-powered laptop, your power settings can cause the webcam to flicker.For example, battery saver mode may reduce the amount of power used by certain features.This can include webcams.Try disabling power saving features.
1. Open Settings > System > Power & Battery and scroll down to the Battery section.
2. The battery saver is only active and editable when the laptop is not plugged in.
3. Disable the battery saver, close the settings, and check if the webcam is blinking.
4. You can also try changing the power mode.If the Windows power plan is set to high performance, you will not be able to change the power mode in settings.
