The FaceTime camera on a MacBook Pro is famously not as good as one on an iPhone, but research shows Apple keeps working on it and may have decided that the answer involves mounting larger cameras on a rotating display. Maybe you don't give the camera notch on the MacBook Pro a second thought. But even if you do and you loathe it, and you believe it's taking up screen real estate, the one thing you can't say is that it is thick.

Rather than necessarily waiting for when it can make slimmer components, however, Apple has been investigating taking a different route. A newly-revealed patent application called "Camera integration for portable electronic devices," totally ignores trying to be slim, and instead focuses on providing the camera system the MacBook Pro needs.…
