Abstract: In one embodiment, a method includes accessing an image captured by an imaging system that includes an aperture and an optical sensor, wherein the imaging system blurs the image; and de-blurring the image by applying an Airy-disk correction that attributes at least part of the blurring in the image to a circular aperture rather than to a pinhole aperture.

Abstract: In one embodiment, a method includes generating, from an accessed image, one or more image patches, and for each image patch: (1) accessing a set of point-spread functions (PSFs), wherein each PSF in the set of PSFs corresponds to one of a plurality of points in the image patch; (2) generating a set of deconvolved image patches by deconvolving the image patch with each PSF from the set of PSFs for that patch; (3) determining, for each of one or more portions of the image patch, a set of weights, wherein each weight in the set of weights is associated with one of the deconvolved image patches; and (4) generating a restored image patch by interpolating the set of deconvolved image patches based on the set of weights.
