I saw this nifty invention last night on an ABC program called the New Inventors. I'm not too sure how it works but it seems to control light in part of the frame, to lower highlights, or raise shadow in oder to give a less contrasty image. It sort of sits between the prime lens and the camera, anyway, here are some links;

Anyway, sort of looks cool and might be able to solve problems of dynamic range, certainly in security cameras and maybe with further prototypes, in the profesional video world.

Ah... yep, OK, seems valid.

Ideally it'd have a lot more than 1M pixels for HD, but even right now you could view it as being rather akin to those LED-backlit LCD panels which use a sub-resolution backlight to increase total dynamic range, which seems to help quite a bit despite the fact that the LED matrix is much lower resolution than the TFT panel itself.

I wonder if it would work better than just making a two- or three-chip HDR prism block with variable exposure to more than one Bayer imager.

That's pretty cool. I can see it being worked into broadcast cameras for all the uncontrolled situations they see, but I don't see something that is essentially automatic being used much in higher end filmmaking.

The other problem I see is with movement. How fast does this thing react to the changing image? Any lag at all will be visible (like a really weird delayed polarized image) and unacceptable.
