Kodak has announced a new sensor which promises to improve the efficiency of CMOS designs with extremely small photosites. The new technology is to be offered initially in 1/4" format suitable for mobile phone cameras but should be scalable to larger formats should the concept prove successful. Conventional designs count electrons which are generated when light hits the silicon from which they are constructed but this new chip works in roughly the opposite fashion, reversing the 'polarity' of the silicon in order to measure an absence of light. The Kodak KAC-05020 also incorporates Kodak's TRUESENSE Color Filter Pattern which adds panchromatic (transparent) filters to the usual Red Green and Blue, further improving luminance sensitivity.
