Windows 8 built in camera randomly doesn't work for some reason, is a "hidden device" on device manager. Help?

So, I use Skype a lot with my friends and at random intervals, it tells me that I do not have a camera, even though it is literally built in into my computer. I open the camera app and it too tells me I am lacking a camera. I checked my device manager and there is no "imaging software" until i click the "view" button and check the "show hidden devices" option. Then it appears in my task manager and the properties option tells me that it is fully functional, is up-to-date, and has no problems whatsoever. In the past, I would uninstall the camera, and that would fix the problem for a little bit. And the other day I uninstalled it and it hasn't showed up.

My laptop is a Windows 8 Dell Inspiron 15-3521 and this problem is not only worrisome, it's extremely annoying and this problem only started to pop up about 2 months ago.
