Webcam Only Displays Black Screen

Hello I recently purchased a new laptop. I have a Dell Inspirion 5559, and recently as of yesterday have run into issues using the webcam. My webcam only seems to work if directly in front of a light. Even with all my lights on if I move it, it will show a black screen. For example all my lights are turned on, but unless it's facing the window where there's sunlight it will just display a black screen.  Here are a couple examples.
