I have been tinkering around with my webcam with the IR filter removed to get a sort of night vision effect. I have this old massive vhs camcorder which I was also tinkering with, so I thought I would open it up and see what its IR filter looks like. When I finally got in there to it I discovered that it is some kind of powered filter. It has four little leds which glow faintly green when powered on. Anyone know what the purpose of this is?

These old cameras have an unbelievable amount of circuitry crammed inside of them.
