Exactly! And that's why it IS enough.

Unlike a Bayer or Foveon chip, the eye has two types of sensors (rods &
cones). Rods are the low light, blue sensitive sensors. There are
120,000,000 rods, but only about 6,000,000 cones which are the colour
sensors. Cones are also the high light sensors. The brain combines these to
from an image. So doesn't work really like a Bayer sensor.

No? Then what is going to be LOOKING at the picture? Certainly if the
ability of the eye to produce an image is matched by the camera, there
is no benefit to be had by improving the camera unless you know some
extraterrestrials who want to look at your photos....

It works EXACTLY like a Bayer sensor because that is why the sensor was
designed as it was, it matches the human visual apparatus.

But the effect is similar in that Bayer provides 4 times as much luminance
(and resolution) information as colour information.

Foveon blindly records colour and luminance at the same resolution and
this has the effect of reducing the efficiency of the sensor as information
that is not needed is provided.

Why would the extraterrestrials necessarily have better vision than a
human? Fact that they evolved on a different planet doesn't
automatically mean they can't be almost blind... Perhaps they have
CCD's cybernetically implanted to enhance their vision...

But I digress...

What now?

Are you trying to communicate with your poor typing skills that the eye
and human brain INTERPOLATE color?

Tell that too the photos hanging on my wall.

Well, that wasn't my point. The point was the eye/brain uses three
types of cones to interpolate color - much as a Bayer sensor does.
