Presumably an organism could perceive a visual stimulus even
if it (the organism) comprised only a head (on a hypothetical
life-support system if you like)? The rest of the body is not
needed for perception to take place.

This is a rather odd statement, considering that we can and do get visual information from touching an object. Eg, shape, orientation.

So what is the minimum
hardware needed to allow visual perception? A brain and an eye
would be sufficient, I think. To demonstrate to other organisms
that perception had taken place, a fluttery eyelid might also
be necessary.

Your question makes no sense without a clear and well-defined notion of "perception." You imply that some sort of response that signals that "perception" has taken place is necessary. OK then, try this:

The minimum hardware is a light sensing diode connected to some activator (eg, s witch that turns on a light or closes bell ringing circuit, or whatever.)

But I don't think that's what you consider as "visual perception." I suspect that you have responses like "I see a tree" in mind when you refer to "visual perception."

This discussion is wandering all over the place and getting nowhere because the posters have differing notions of "perception", which is bad enough. But it gets worse: most change their notions every time they write another sentence.
