    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?

    It seems like you are describing autostereoscopic 3-d tv.

    THanks, these are quite interesting links, indeed its similar. It appears that at this stage of R&D the displays are mostly limited to 2 angles (one for each eye) to emulate a 3D effect, each angle displaying the input of 2 flat camera sensors where all pixels in the array record a single angle, as opposed to a sensor array that is itself composed of lenticular lenses or concave micro-panels(with many pixel recorders) that record light from many angles. Perhaps further down the road it will be possible to improve the lenticular lense displays with a lot more resolution and viewing angles so that viewers perceive a continous image that coincides with their viewing angle.


    the way I imagine it is a convex or concave version of fly-eyes (multi-facet dome or multi-facet dome depression) for both the camera sensor and the screen panel. Each of these tiny bug eye would be the size of a current tech pixel but with miniaturization would actually contain a hundred or so pixels recording and emitting at a specific angle:


    Unlike the 3D displays, instead of having many people seeing the exact same image in what appears to be 3D, many people would see a very slightly different image (in what might appear to be 3D) depending on where they are viewing the image from (like a window), the scene from multiple angles would be recorded and displayed and people on the right of the panel would see a little bit more of what can be seen to the left of the camera/screen, idealy like a window.
