Next Sony foveon alike patent!

 

Egami (translation here) spotted the next Sony sensor patent describing a Foveon alike sensor. With Foveon alike I mean a RGB 3-layer image sensor that in case of the Sony patent also includes tilted(!) pixels. As you know the advantage of such a 3 layer sensor is the color accuracy, sharpness and larger pixels (or possibility to have more pixels on the same sensor size). Now, it’s hard to understand from the google translation why these pixels have been titled. But if you saw some test of the latest generation Sigma Foveon sensor cameras than you will easily notice that at Low ISO the sensor really rocks! (while there are still massive noise problems on High ISO images).
Here are some test to check out:  DP2 ISO test at Focus Numerique. A full camera review has been posted at Photographyblog, Luminous Landscape and ePhotozine.

I hope Sony will be able to overcome some of the Sigma Foveon technology limits and release a camera with a 3 layer sensor. Would push the image quality to a new level!

P.S.: There are two 46 Megapixel Merrill compact cameras from Sigma:
DP1 with 28mm lens at Amazon, BHphoto and of course on eBay.
DP2 with 45mm lens at BHphoto and on eBay.
