      From: jvorbrueggen-not@mediasec.de               > But if there is       > noticeable motion at the time of the exposures, then you can't get a clear       > picture with that approach, so they just go with a monochrome image.              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.               Jan              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
