How does an eye reconstruct an image?

[QUOTE="Salmone, post: 6832806, member: 698014"] I would like to understand the relationship between the image formed on the retina and the image reconstructed by the human eye. Let's consider this images: [ATTACH type="full" alt="CNX_UPhysics_35_07_AngleMag (1).jpg"]318968[/ATTACH] The object B forms the real image OB' while the object A forms the real image OA' on the retina. Second image: [ATTACH type="full" alt="gfggd.PNG"]318969[/ATTACH] here, the object forms a virtual image ##h_i##. My question is: what is the correlation between the image defined in geometrical optics as the the point where the emerging rays converge and the image recreated by our brain? For example, in the second image, there is an image formed on the retina and a virtual image ##h_i##, where do we see the object? I think it is ##h_i##, if so, where do our brain reconstruct the images of the first picture? The point where cones and rodes are hitted by light on retina, what kind of informations gives us about where to reconstruct the image? Like: rays of light start from the arrowhead A and travel to the eye, here there is a lens which focuses all the rays into a certain point on the retina depending on where the rays started from; what happens then? I don't want an answer related to medicine of course, I just can't understand correlation between image on the retina and image our brain let us see. [/QUOTE]
