20130128087 | Methods and Apparatus for Super-Resolution in Integral Photography - Methods and apparatus for super-resolution in integral photography are described. Several techniques are described that, alone or in combination, may improve the super-resolution process and/or the quality of super-resolved images that may be generated from flats captured with a focused plenoptic camera using a super-resolution algorithm. At least some of these techniques involve modifications to the focused plenoptic camera design. In addition, at least some of these techniques involve modifications to the super-resolution rendering algorithm. The techniques may include techniques for reducing the size of pixels, techniques for shifting pixels relative to each other so that super-resolution is achievable at more or all depths of focus, and techniques for sampling using an appropriate filter or kernel. These techniques may, for example, reduce or eliminate the need to perform deconvolution on a super-resolved image, and may improve super-resolution results and/or increase performance. | 05-23-2013 |
