They will each have a slightly different view of the thing that you are taking a picture of. There are some mathematical models you can use to sort of "reverse ...

In a traditional digital camera the incoming light is focused onto a plane, the sensor, which measures brightness at each photosensitive cell, pixel. This produces a final image in the sense that the resulting raster of values can be plotted as a coherent image. A light-field ...

I'm not sure about reference code; this is relatively new, and mostly what I can find are papers, not implementations with open code. A key paper is Fourier Slice Photography, by Ren Ng at Stanford University — now, not surprisingly, at Lytro. There's an abstract of the paper here, with a few nice pictures. This doesn't give you something that you can take ...
