Abstract
Methods and apparatus for super-resolution in focused plenoptic cameras. By examining the geometry of data capture for super-resolution with the focused plenoptic camera, configurations for which super-resolution is realizable at different modes in the focused plenoptic camera are generated. A focused plenoptic camera is described in which infinity is super resolved directly, with registration provided by the camera geometry and the microlens pitch. In an algorithm that may be used to render super-resolved images from flats captured with a focused plenoptic camera, a high-resolution observed image is generated from a flat by interleaving pixels from adjacent microlens images. A deconvolution method may then be applied to the high-resolution observed image to deblur the image.
