A CDE Definition
(1) (Phenom X3) A triple-core processor from AMD. See Phenom.
(2) A full-color image sensor for still and video cameras from Foveon, Inc., Santa Clara, CA (www.foveon.com). Introduced in 2002, the CMOS-based X3 chip is more analogous to film than the CCD and CMOS chips in common use because it stores all three colors (red, green and blue) in each pixel. In addition, traditional sensors capture only one third of the color per pixel, using a checkerboard-like mosaic of red, green and blue pixels that have to be interpolated by complex processing. The interpolation often causes unwanted effects such as "purple fringing," which is a line of color outlining dark areas such as brown or black hair. See Bayer pattern and purple fringing.
