NASA's Mars probe: NO cmos, NO Bayer
RichA wrote:
from Amateur Photography magazine; The camera has a double Gauss lens system, a design commonly used in 35mm cameras,' explains the space agency. 'Images are recorded by a charge-coupled device (CCD) similar to those in consumer digital cameras. The instrument includes sets of red, green and blue light-emitting diodes (LEDs) for illuminating the target area.' Nasa claims that the camera can focus down to 11mm and record images at a resolution of '23 microns per pixel' at the closest focusing distance - allowing the camera to show details 'much finer than the width of a human hair'. This means tri-colour imaging through three different filters onto a monochrome CCD. Nice try, Captain Obvious, but that's not what it means. It means the light sources providethe three colors, and no filters are necessary. |
