New Imaging System Promises 12-Times More Color Sensitivity than a Traditional Sensor

What's the use of an image sensor that's 12 times more color sensitive than the human eye? We're not entirely sure, but thanks to a team of researchers at Universities of Granada, Spain and Polytechnic University of Milan, Italy you may someday get to try it out and find out for yourself.

Researchers at those two universities are using "Transverse Field Detector" technology to distinguish 36 individual color channels without any need for a filter, making it 12-times more color sensitive than standard Red/Green/Blue sensors and the human eye both.

Sigma Tests Show the Foveon Sensor Can Out-Resolve Conventional 36MP Shooters

Sigma took a unique approach when it worked together with its sensor subsidiary, Foveon Inc., to build the newest version of Foveon sensor found in the DP Quattro camera.

Using technology that captures light simultaneously across three separate layers of sensors -- one each for blue, red, and green -- Sigma claims that, while smaller, the sensor is actually capable of out-resolving a 36-megapixel full frame sensor similar to those found in the Nikon D800E and Sony A7r.
