Focused Plenoptic Camera and Rendering Focused Plenoptic Camera and Rendering
Plenoptic cameras, constructed with internal microlens arrays, capture both spatial and angular information, i.e., the full four-dimensional radiance, of a scene. The design of traditional plenoptic cameras assumes that each microlens image is completely defocused with respect to the image created by the main camera lens. As a result, only a single pixel in the final image is rendered from each...
متن کاملPlenoptic Camera Resolution
To resolve the low resolution problem of Plenoptic cameras we analyze optical signal sampling at frequencies above Nyquist. The resultant aliased signal is superresolved interleaving the array of microimages, thus cancelling the aliasing components. The rendered image can reach full sensor resolution. OCIS codes: (100.6640) Superresolution; (110.1758) Computational imaging; (110.5200) Photograp...
متن کاملEvaluation of multispectral plenoptic camera
Plenoptic cameras enable capture of a 4D lightfield, allowing digital refocusing and depth estimation from data captured with a compact portable camera. Whereas most of the work on plenoptic camera design has been based a simplistic geometric-optics-based characterization of the optical path only, little work has been done of optimizing end-to-end system performance for a specific application. ...

bstract. Plenoptic cameras, constructed with internal microlens rrays, capture both spatial and angular information, i.e., the full 4-D adiance, of a scene. The design of traditional plenoptic cameras ssumes that each microlens image is completely defocused with espect to the image created by the main camera lens.

متن کاملLight field panorama by a plenoptic camera
Consumer-grade plenoptic camera Lytro draws a lot of interest from both academic and industrial world. However its low resolution in both spatial and angular domain prevents it from being used for fine and detailed light field acquisition. This paper proposes to use a plenoptic camera as an image scanner and perform light field stitching to increase the size of the acquired light field data. We...
