When looking through a window, what you see changes slightly depending on your angle of view, when you are on the right you can see a little bit more of what's on the left and vice versa.
It would be interesting if we could devise cameras in which each pixel is replaced by a pixel cluster(7-16) behind a tiny (concave/convex) lense and have a screen tv which uses clusters of pixels behind a tiny (concave/convex) lense.
The idea would be to give the effect that would make the tv screen similat to a window, so that when looking from the right side of the screen you see an image formed from the image to the left of the camera micro-lense array.
I wonder if with high enough resolution per micro-cluster, the effect could be enough for poeple to experience the tv as if it were a window?
Actually, in the future given nanotechnology, with very high resolution of micro-lenses and very high resolution of pixels per micro-lense, wouldnt it be like a 3D television without the glasses?
