Default NASA's Mars probe: NO cmos, NO Bayer

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.

I doubt that. What about ambient light? and the shots shown on the box
go out to infinity at the top of the vertical pan. Some leds!

The article says the sensor is similar to consumer digital cameras.
That means a Bayer matrix.
