Abstract

A floating-image display technique, which can project two-dimensional images into a real space through a convex lens or a concave mirror, has been studied as a new approach for implementation of the next-generation three-dimensional (3D) display system. However, the conventional floating-image display system was implemented just by using active display devices such as LCD panel and it could provide only a real plane image in space to an observer comparing with other 3D display systems having different perspectives. For practical application of a floating-image display system to 3D display systems, multi-layered display structure might be required to present multi-depth images in space. In this paper, a novel floating-image display system composed of two plane images with different depth by use of a half mirror is proposed. One plane image of an object is provided with the conventional floating-image display system to present and the other plane image of a background is provided with the integral imaging technique. Therefore, the proposed display system can provide high-resolution floating images with background images having different perspectives to observers. To show the usefulness of the proposed system, some experiments are carried out and the results are presented as well.
