Single Lens Stereo with a Plenoptic Camera
Edward H. Adelson and John Y.A. Wang
Abstract--Ordinary cameras gather light across the area of their
lens aperture, and the light striking a given subregion of the
aperture is structured somewhat differently than the light striking an
adjacent subregion. By analyzing this optical structure, one can
infer the depths of objects in the scene, i.e., one can achieve
"single lens stereo." We describe a novel camera for performing this
analysis. It incorporates a single main lens along with a lenticular
array placed at the sensor plane. The resulting "plenoptic camera"
provides information about how the scene would look when viewed
from a continuum of possible viewpoints bounded by the main lens
aperture. Deriving depth information is simpler than in a binocular
stereo system because the correspondence problem is minimized.
The camera extracts information about both horizontal and vertical
parallax, which improves the reliability of the depth estimates.
