摘要： Methods, apparatus, and computer-readable storage media for rendering focused plenoptic camera data. A rendering with blending technique is described that blends values from positions in multiple microimages and assigns the blended value to a given point in the output image. A rendering technique that combines depth-based rendering and rendering with blending is also described. Depth-based rendering estimates depth at each microimage and then applies that depth to determine a position in the input flat from which to read a value to be assigned to a given point in the output image. The techniques may be implemented according to parallel processing technology that renders multiple points of the output image in parallel. In at least some embodiments, the parallel processing technology is graphical processing unit (GPU) technology.

摘要： Methods and apparatus for reducing plenoptic camera artifacts. A first method is based on careful design of the optical system of the focused plenoptic camera to reduce artifacts that result in differences in depth in the microimages. A second method is computational; a focused plenoptic camera rendering algorithm is provided that corrects for artifacts resulting from differences in depth in the microimages. While both the artifact-reducing focused plenoptic camera design and the artifact-reducing rendering algorithm work by themselves to reduce artifacts, the two approaches may be combined.

摘要： 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.

摘要： Methods and apparatus for rich image capture using focused plenoptic camera technology. A radiance camera employs focused plenoptic camera technology and includes sets of modulating elements that may be used to modulate the sampling of different aspects of the range of plenoptic data. The radiance camera, via the modulating elements, may capture a particular property of light, such as luminance, color, polarization, etc., differently in different microimages or in different portions of microimages. With the focused plenoptic camera technology, the microimages are captured at the same time in a single image. Thus, multiple microimages of the same image of a scene may be captured at different exposures, different colors, different polarities, and so on, in a single image at the same time. Captured images may be used, for example, in High Dynamic Range (HDR) imaging, spectral imaging, polarization imaging, 3D imaging, and other imaging applications.

摘要： 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.
