I just ran across this news release, that is no longer news. It seems to propose the equivalent of a global shutter for CMOS sensors. They say all pixels would be exposed simultaneously, then the response would be stored in the silicone at the base of the pixels, until the next scan swept by. It doesn't seem to have been implemented in any camera with which I'm familiar. Anyone else know anything about it?

That would be great to see happen.

This is 2 years ago, the problem is mass producing these sensors and making it affordable for implementation. Omnivision also promised a Global Shutter sensor for phones a while back, but we haven't heard of anything from them since.

German company Viimagic apparently is the only company doing 2/3'' CMOS sensors with global shutters. No word of their pricing, and apparently China is interested in the sensors.

Still, what is key is high speed, low noise, and high dynamic range. We don't have affordability with all those factors so consumer and prosumer cameras can't implement them yet.
