The camera in the WIN10 system is just like the phone. Application access needs to be given access rights, if the application is not given permission to access the system's camera oh, let's open the camera.
1. We click "Start menu-Computer settings" in the computer
2. In the Open Computer Settings window, we find "privacy" entry to the next action. As shown in the following figure
3. Then find the system "camera" click on Open. As shown in the following figure
4. Click will allow the application to use my camera to open and close the Computer Settings window to complete the operation. As shown in the following figure
All right, so when you turn on the switch, you'll find that the problem with the camera can't be opened is gone, which is just like the permissions set up by the phone, without giving permission to other applications that can't access the camera.
