There's been a lot of debate on our discussion forums about the use of the "x 3" notation after the pixel count when describing Foveon's X3 sensors. After a meeting with Foveon at PMA they made clear that they feel that they conform to published JCIA (Japan Camera Industry Association) guidelines which say "For DSCs that use a plurality of image sensors, the number of image sensors and the number of effective pixels corresponding to each image sensor shall be noted." Obviously this standard was published before Foveon announced their new technology but the use of "x 3" does seems logical enough.
