[filmscanners] Re: Foveon patent

["Jack Jansen" <jackjansen@bwn.net>]

Just as a point in space can be defined in terms of coordinates that aren't
orthogonal, I would think that a color can be defined in terms of components
that aren't as orthogonal as RGB or CMY.  I would guess that Faveon takes
what they get with the silicon, and then performs a transformation to get
the conventional components.
