The panoramic shots are made with the Surface Stereo Imager (SSI),
which is mounted on a mast extending above the spacecraft. This
imager has two sensors and two lens systems, to produce the stereo
images. Each sensor has a filter wheel containing twelve separate
filters, including a red filter and a blue filter (see
http://www.met.tamu.edu/mars/SSI_filter.html for details on the
filters). By combining images using two different filters, a false
color image can be produced, but the colors produced are not really
what the human eye would perceive.
Uh. Look closely: the right eye has filters at 447 or 450, 532, 603,
and 671 nm. This is perfectly adequate for full color inmagery.
The filters are a bit narrow band, but this is not terribly much a problem.
It is limited to two-color stereo.
