Abstract

When the exposure is over, the focused plane and depth of field(DOF) is definite. It is necessary for us to properly adjust the aperture size, exposure time and focus before we take photos. The paper deduces a patch-to-patch reconstruction algorithm from the structure of focused plenoptic camera proposed by Georgiev and Lumsdaine. It can not only build a high resolution refocus image, but supply us with the capability of DOF control after the exposure, just like we take photos under different aperture sizes. With the algorithm, we can always shoot picture under the maximum aperture size to maintain the best SNR result, and render the image taken at desired focused plane and DOF from the light field data of the scene on computer. And the simulation result indicates that the proposed algorithm is feasible and effective.
