Abstract

Viewing angle enhanced integral imaging (II) system using multi-directional projections and elemental image (EI) resizing method is proposed. In this method, each elemental lens of micro lens array collects multi-directional illuminations of multiple EI sets and produces multiple point light sources (PLSs) at the different positions in the focal plane; and the positions of the PLSs can be controlled by the projection angles. The viewing zone is made consisting of multiple diverging ray bundles, wider than the conventional method, due to multi-directional projections of multiple EI sets; whereas a conventional system produces a viewing zone using only a single set of EI projection. Hence the viewing angle of the reconstructed image is enhanced.
