How do the light gun video games work?

I was especially wondering how the hardware detects where the point on the screen is when only the TV is connected to the console via an RF cable? Is there a camera in the gun or does the point of light that hits the screen transmitted back through the TV RF cable to the hardware?

Originally it was a photocell in the gun. (The barrel had to be long enough to block out all but the desired trigger light.) Modern games may well have a camera and recognition software.
