<P>Not at all. The engineering of the eye has the same constraints as any
|
|
<BR>
|

engineering humans do. The eye uses three sensor channels. If we do the same in
|
|
<BR>
|
|
imaging systems, we can fool the eye into thinking an image is a reasonably
|
|
<BR>
|
|
accurate representation of the original. There is no luck involved. To an
|
|
<BR>
|
|
animal with different colour sensing our TV pictures probably look very odd. I
|
|
<BR>
|
|
wonder what a dog thinks of a TV's colour fidelity?
