The basic idea is that it's problematic to think of vision as being like a camera that projects content onto a screen in the brain, because that just prompts the question of how that internal projection is seen--and we have a regress.

Not really - it could form a straightforward pixelated representation in the cortex (an image, in my book) that's only then processed - but it's false anyway (e.g., the retina does edge detection).

However, an image certainly does form on the retina just as much as it does in a camera.
