well, its continuous, right? so in theory I am sampling it with infinite precision, right? ok, lets say its limited by the amount of neurons in my retina. These still send out analogue signals (ok, no - they actually send digital signals, but the frequency of these digital impulses varies on a continuous spectrum).
I was under the impression, that this would accumulate to a very high data throughput.
If I am wrong, and you have some sources on the topic (or a simple explanation), please post some links. I would find this very interesting.
