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.
