Integral imaging system using an array of planar mirrors

摘要

A lens array consisting of microlenses is normally used when shooting or displaying three-dimensional (3-D) images of a subject with use of the integral photography (IP) method. Elemental images that are produced through many microlenses (elemental lenses) are acquired during shooting, and spatial images using elemental images and lens array are produced during display. In this case, geometric distortions and chromatic aberrations of elemental lenses cause reconstructed images to deteriorate. Shooting and displaying have been done with use of a planar mirror instead of elemental lens in order to avoid these causes of deterioration. A pseudoscopic image where depth is reversed is produced in the structuring where a planar mirror is used. In this paper, an orthoscopic image that is produced by the use of a planar mirror array and gradient-index lens array has been confirmed. In addition, a method of avoiding pseudoscopic images by using differing mirror arrays in the shooting equipment and display setup has been proposed, and the confirmation of the effects through the experiment has been confirmed.
