“…Since Lippmann first reported 34 a static integral photography display, many light field video displays have been proposed. [34][35][36][37][38][39] In these displays, numerous elemental images are arranged vertically and horizontally, and a microlens array (MLA) is used to control the directions of light rays and other applications of the HOE have been reported. However, in the previous research, the HOEs were fabricated by copying a phase distribution generated by real existing optics, such as MLAs, objective lenses, or optical diffusers.…”

Abstract. Several wavefront printers have been recently proposed. Since the printers can record an arbitrary computer-generated wavefront, they are expected to be useful for fabricating complex mirror arrays used in front projection 3-D screens without using real existing optics. We prototyped two transparent reflective screens using our hologram printer in experiments. These screens could compensate for a spherically distorted reference wave caused by a short projection distance to obtain an ideal reference wave. Owing to the use of the wavefrontprinted screen, the 3-D display was simply composed of a normal 2-D projector and a screen without using extra optics. In our binocular system, reflected light rays converged to the left and right eyes of the observer and the crosstalk was less than 8%. In the light field system, the reflected light rays formed a spatially sampled light field and focused a virtual object in a depth range of AE30 mm with a AE13.5-deg viewing angle. By developing wavefront printing technology, a complex optics array may easily be printed by nonprofessionals for optics manufacturing.

“…They realized an integral 3-D image consisting of ∼100;000 pixels using the projector. 11 However, it is currently difficult to fabricate a single display element that significantly exceeds 8K, and it is difficult to improve the performance of an integral 3-D image further using a single display device.…”

Abstract. We propose a method for arranging multiple projectors in parallel using an image-processing technique and for enlarging the viewing zone in an integral three-dimensional image display. We have developed a method to correct the projection distortion precisely using an image-processing technique combining projective and affine transformations. To combine the multiple viewing zones formed by each projector continuously and smoothly, we also devised a technique that provides accurate adjustment by generating the elemental images of a computer graphics model at high speed. We constructed a prototype device using four projectors equivalent to 4K resolution and realized a viewing zone with measured viewing angles of 49.2 deg horizontally and 45.2 deg vertically. Compared with the use of only one projector, the prototype device expanded the viewing angles by approximately two times in both the horizontal and vertical directions.

“…We have been developing a 3D capture system by means of an 8K Super Hi-vision (8K) camera 7 and pixel-offset technique to improve the quality of the 3D image. 8 However, it is difficult to develop a 3D capture system by means of a single camera because cameras with much more than 8K pixels are not available at present.…”

A three-dimensional (3D) capture system based on integral imaging with an enhanced viewing zone by using a camera array was developed. The viewing angle of the 3D image can be enlarged depending on the number of cameras consisting of the camera array. The 3D image was captured by using seven high-definition cameras, and converted to be displayed by using a 3D display system with a 4K LCD panel. It was confirmed that the viewing angle of the 3D image can be enlarged by a factor of 2.5 in horizontal and vertical directions compared with that of a single camera.
