Online, I found this pretty cool demo of sub-aperture images as a result of a plenoptic camera. Here, you can play around with optical and triangular parameters to get some interesting estimation results: http://www.plenoptic.info/pages/sub-aperture.html

By changing (u, v) coordinates and keeping (x, y) fixed, we can shift perspective - is this the correct understanding?

@hershg, yes! because the pixels are at slightly different locations on the lens, it's equivalent to moving 1 pinhole camera's lens slightly and getting a different picture.
