Device and process for the contemporary capture of standard images and plenoptic images via correlation plenoptic imaging

Abstract

A process and device for the plenoptic capture of photographic or cinematographic images are described, both based on the correlation measure or 'Correlation Plenoptic Imaging' (CPI), comprising the steps of splitting a primary light beam () coming from at least one light source in at least two distinct light beams (), directing said distinct light beams towards two image capturing sensors to capture images, so that the first light beam is directed towards at least one first capturing sensor to capture a spatial measure of a scene and the second light beam is directed towards a second capturing sensor to capture an angular measure of said scene, said angular measure being adapted to provide the propagation direction of the light beam coming from the scene, said spatial measure being adapted to provide the conventional two-dimensional capture of the image of the scene. The device further comprises a main focal lens (Lb) arranged along the optical path of the first light beam, said main focal lens (Lb) and second sensor () being arranged so that the length of the light's optical path between the light source () and the second sensor () is substantially equal to the length of the light's optical path between the light source () and said main focal lens (Lb).
