1. A method comprising: capturing a primary image representation with a photo-detector array at a primary position; associating a primary set of discrete portions of the primary image representation with one or more defined virtual lenslets of a lens; moving the photo-detector array to another position; capturing another image representation with the photo-detector array at the other position; associating another set of discrete portions of the other image representation with the one or more defined virtual lenslets of the lens; and assembling a volumetric image from those virtual lenslet associated portions of the primary and the other image representation that have relatively sharper focuses.
