NASA's Mars probe: NO cmos, NO Bayer

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. What bothers me is that there's no diffusion for a nice portrait should it run into something sentient... -- Blinky Killing all posts from Google Groups The Usenet Improvement Project -- http://improve-usenet.org Found 5/08: a free GG-blocking news *feed* -- http://usenet4all.se |
