Finally, a Foveon based Digital Video camera

This single chip camera should give excellent 3 CCD like results...

http://www.alt-vision.com/HVDUO-5M.html

640x480 30 FPS
1420 x 1064 7 FPS

It doesn't have the frame rate for HD, but SD results would give great uncompressed video output. Pity it's not USB2 or FW800 interface.

No idea on cost yet.

The resolution can barely pass for SD and the thing is using a
rolling shutter which is another thing you basically don't want
(especially without motion blur).

Anyone know what the price of this thing would be?

I think when this sensor technology was first announced last fall they were tossing around $800 US for just the sensor in production amounts. They hoped they could integrate more frame storage buffering and DV compression on-chip later, but... that's one heck of a large chip already! 2/3 inch active area is a huge amount of silicon, so unless they can shrink to smaller geometry, the price won't fall much or fast.


Edit - Erk. I lost a year. It was about two years ago I first read about this tech. Sorry. I see from google there's some still Foveon cameras going for about $1,100 US.

depending on what range and pixel sizes you could use with this thing you should be able to get 720 x 540 at 24 fps. The total number of pixels to calculate per second falls between the 640 x 480 x 30 and the 1420 x 1064 x 7.

With this you could get an SD video by scaling the 720 x 540 down to 720 x 480.
