Strange Effect On CCTV Video - What Is The Cause?
It seems where the picture gets overexposed instead of being white it goes black. Or is something else happening? Warning: Brutal karate kick inside!
It's over-exposure compensation. I've seen several cameras do that where a really bright area actually gets displayed as black pixels.
It seems that the cameras have HLC (High Light Compensation) on in the camera. That is why you see the really bright areas , especially the whites get blackend out.
Is that a generic term, HLC, or specific to a manufacturer? Is it designed really just as a 'clip indicator' (like the red of a audio VU meter) and so you should never see more than just a small amount of blackening, or is the way the video clip looks typical?
