We propose a curved integral imaging system with large depth achieved by
the additional use of a large-aperture lens in a conventional large-depth integral imaging
system. The additional large-aperture lens provides a multidirectional curvature effect and
improves the viewing angle. The proposed system has a simple structure due to the use of
well-fabricated, unmodified flat devices. To calculate the proper elemental
images for the proposed system, we explain a modified computer-generated pickup
technique based on an ABCD matrix and analyze an effective viewing zone in the proposed
system. From experiments, we show that the proposed system has an improved viewing
angle of more than 7° compared with conventional integral imaging.
