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 کاملSingle Lens Stereo with a Plenoptic Camera
Ordinary cameras gather light across the area of their lens aperture, and the light striking a given subregion of the aperture is structured somewhat differently than the light striking an adjacent subregion. By analyzing this optical structure, one can infer the depths of objects in the scene, i.e., one can achieve “single lens stereo.” We describe a novel camera for performing this analysis. ...
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 کاملSuperresolution with Plenoptic Camera 2 . 0
This work is based on the plenoptic 2.0 camera, which captures an array of real images focused on the object. We show that this very fact makes it possible to use the camera data with super-resolution techniques, which enables the focused plenoptic camera to achieve high spatial resolution. We derive the conditions under which the focused plenoptic camera can capture radiance data suitable for ...
متن کاملSuperresolution with the focused plenoptic camera
Digital images from a CCD or CMOS sensor with a color filter array must undergo a demosaicing process to combine the separate color samples into a single color image. This interpolation process can interfere with the subsequent superresolution process. Plenoptic superresolution, which relies on precise sub-pixel sampling across captured microimages, is particularly sensitive to such resampling ...
