Multi-layer CCD
From Wikipedia, the free encyclopedia
The term Multi-layer CCD has been used to describe a CCD image sensor that captures true RGB using stacked CCD sensor layers. This concept was originally part of an April Fools joke press release from dpreview.com. When the joke was released in 2000, a remarkably similar device was under development at Foveon—the Foveon X3 image sensor, which is multi-layered but is not a CCD. The Foveon sensor was announced on dpreview.com in 2002, with sample images.
