With mosaic sensor cameras, one sensor usually maps to one output pixel. This means that two out of three channels for every output pixel are interpolated. Fuji is even worse with their double size images--only every other output pixel has a single color sensor. So 5/6ths of the information is interpolated. Only Foveon chip cameras currently have three sensors per output pixel. The Nikon D1X is just a normal Bayer pattern camera (with non-square pixels), so 2/3rds of the values are interpolated. It is NOT a three sensor per pixel camera. Some people in this thread are confused--they somehow think that multiple mosaic tiles are being combined into a single output pixel. This is NOT the case.
