Attempt to use Windows Update to see if there's an updated driver for the camera device. To update the drivers using Windows Update, see the following article:

Automatically get recommended and updated hardware drivers

If there wasn't an updated driver on Windows Update, or the updated driver on Windows Update didn't fix the problem, try using the generic USB Video Device driver:

1. Right-click on the Start menu and then select Device Manager.

2. In the Device Manager window that opens, select the arrow next to Cameras to expand the category.

3. Under the expanded Cameras category, right-click on the camera having the issue and select Properties.

4. In the camera Properties window that opens, select the Driver tab.

5. In the Driver tab, select the Update driver button.

6. In the Update Drivers window that opens, select Browse my computer for drivers.

7. In the Browse for drivers on your computer window, select Let me pick from a list of available drivers on my computer.

8. In the Select the device driver you want to install for this hardware window, select USB Video Device, and then select theNext button to install the driver.

9. In the Windows has successfully updated your drivers window, select the Close button.

Another option to try to fix the problem is to download an updated camera driver directly from the camera manufacturer's website. The first step in this process is to try to determine the camera's manufacturer and model number:

1. Right-click on the Start menu and then select Device Manager.

2. In the Device Manager window that opens, select the arrow next to Cameras to expand the category.

3. Under the expanded Cameras category, right-click on the camera having the issue and select Properties.

4. In the camera Properties window that opens, under the General tab, determine the manufacturer's name next to Manufacturer. The window might also contain information about the specific camera model or name.

   Note: If the manufacturer is listed as Microsoft, the camera might be using a generic driver. Refer to the documentation that came with the camera for more information on the camera manufacturer. If the camera is built into a Windows device, refer to the Windows device's documentation or the Windows device manufacturer's website.

Once the camera manufacturer and model/name are determined, use the information to find the manufacturer's website and driver download page via a search engine. For more information, including how to install the driver downloaded from the manufacturer's website, see the Update driver manually section in the following article:
