If it was like imagination then the vision program would be able to
change what it was trying to see. Since the images come from outside
the program (perhaps they were generated years ago by another computer
and are merely stored on disk), they are an objective feature of the
program's world. It is not at all like imagination.

If it looks like it is walking (it moves around its world) and thinks
it is walking, then what is the difference? I suppose you could define
"walking" narrowly enough to exclude what the simulated cockroach is
doing, but that is like saying computers don't do math until the results
are printed on paper.
