Reading this made me appreciate again the specialness of the human eye.
One sensor for b&w and movement, and another for full spectrum color.
Wonder what it would cost to manufacture, and how big it would be if man made?

I was browsing a physiology book and it had the following numbers:
120 million rods (b/w low light)
6 million cones. (color)
Of course the foveal area only has cones and at the highest density and this
part is then scanned over the image for maximum resolution at the area of
interest, so the numbers don't give the full story. But this still makes
current state of the art digital sensors at about 16million pixels look
rather small. Unfortunately the book did not have the cost to manufacture but
you can figure on at least twenty years of parenthood.
