Claim One:
1. A system for recording an image on a sheet as digital data, comprising: a photosensor array comprising a plurality of photosensors, the photosensor array configured to receive light reflected from the sheet and to output image data as digital signals during a scanning operation; a plenoptic set, including a main lens and a lenticular grating, the plenoptic set being disposed to convey light from the sheet to the photosensor array, to enable the photosensor array to obtain the image data from the sheet during the scanning operation as plenoptic image data; and an image processing system configured to select, from a set of plenoptic image data associated with an image, a subset of the plenoptic image data based on an algorithm to obtain image data for a focused image, wherein the set of the plenoptic image data has different object distances, the selected subset of the plenoptic image data has a predetermined focus, and the image processing system is configured to select the subset of the plenoptic image data after the scanning operation is performed.
