Acer aspire 3 dark camera

I have acer aspire 3 a315-51 that has win10 x64.

I was speaking with my friend on skype perfectly but then the cameras became dark!

It’s not off, but I can only see my face only if I make it very close it (even though it’s not clear).

I uninstalled the camera driver from the device manager and restarted the laptop but nothing was rewarding.

Suggestions?
