Light is always important and the brights and shadows or range of light we
see in is real important too. As we age we need more light to make out the
letters of the written word, more light to see in the dark too, and our eyes
are much more high tech than any cmos or ccd sensor.
CCD, actually even with lower resolution rating, will give a clearer
picture than a cmos cam. Much sharper per size of imager Larger imagers are
important considerations too but it really depends.... |

Yep, I'd agree. My best two webcams are both ccd, and far outstrip the
cmos one I have (though, to be fair, the cmos *is* older, but not by
that much).
I'd definitely be looking for a ccd sensor in the next webcam I buy.
Mine are good enough to be able to make out shapes of things (but not,
obviously details) under streetlights or porch lights at night, which I
think is pretty good going, considering - and my cmos one was hopeless
for anything more than just dark noise in a room with dim lighting.
