Abstract
In this paper, we propose a novel performance-enhanced computational integral imaging reconstruction (CIIR) system by use of elemental image array (EIA) obtained by using a simultaneous pickup scheme of far three-dimensional (3-D) objects from the lenslet array in both real and virtual image fields. In the proposed system, an imaging lens between lenslet array and 3-D objects to overcome limitation of pickup range is introduced, the EIA through additional imaging lens is recorded with image sensor, and the pickuped EIA is reconstructed by use of CIIR technique. Additional imaging lens produces an image shift effect of 3-D objects located far away from the lenslet array. To show the usefulness of the proposed system, some experiments are carried out for real 3-D objects and its results are presented.
