What is it with the Foveon X3 technology?
Foveon developed a new type of image sensors that can capture full red, green, and blue light at each sensor. The sensors in conventional digital cameras have to use mosaic color filter array because they only detect one color per location. Foveon’s patented X3 technology should improve the sharpness and quality of pictures if it can be produced cheaply enough to be competitive with traditional CCD sensors. It is not yet used in any quality consumer-level cameras.
