   For those cases, you have (automatic) image registration, if the various   
   colour views are largely overlapping. One problem here seems to be the slow   
   readout speed - apparently, Cassini needs about one minute to acquire one   
   image.   
      
   The big other advantage of this approach is reduced aliasing - on a consumer   
   camera, only about 40% or so of the chip are is "active", and each colour   
   channel has about a third of that. Unless, of course, you are using a camera   
   with a Foveon chip in it.
