Three-dimensional projection integral imaging using micro-convex-mirror arrays.

Abstract: Three-dimensional projection integral imaging using micro-convex-mirror arrays is presented. In this scheme, a pseudoscopic to orthoscopic image conversion process is not required even if elemental images of direct camera pickup are used. In addition, a wide viewing angle without image flipping can be achieved even if optical barriers are not used. The feasibility of the proposed scheme was experimentally demonstrated, in which the viewing angle of more than 60 degrees was obtained. To the best of our knowledge, this is the largest viewing angle demonstrated by a single integral imaging system.

Vector representation of binary images containing halftone dots

Abstract: Vector representation of graphics has the advantage that the image can be displayed at any size. When the resolution of a bitmap image is changed, the lack of a line segment arises. In addition, moire occurs when the resolution of an image with halftone dots is changed. We propose a new technique to convert a binary image with halftone dots into its vector representation. Resolution conversion of a binary image can easily be performed without moire by using a continuous tone approximation of the halftone dots. First, we separate the area of halftone dots and line drawings in the image. Next, a continuous tone approximation is applied to the area of halftone dots. Then, conventional vectorization is applied to both continuous tone areas and line drawings. Finally, these components are mixed and reconstructed. Our approach provides an efficient way of displaying cartoon-like images at any size with a limited amount of data.

Video display system

Abstract: PROBLEM TO BE SOLVED: To solve the problem of a conventional video display system that needs physical processing of a polarized plate and cannot have coped with the case wherein an image (a latent image) is sequentially changed, the latent image being hidden in the video image and visible when a user wears polarization eyeglasses. SOLUTION: The video display system disclosed herein includes: two image projectors; a polarization means; and a display image data generating apparatus. The display image data generating apparatus gives original image data and latent image data to the first image projector and gives display image data resulting from superimposing the latent image on an original image to the second image projector. The display image data generating apparatus generates the display image data in a way of compensating a lost part of the original image by superimposing the latent image on the original image. Each of the image projectors uses an image conversion means to convert the received display image data so that corresponding pixels are displayed mutually on the same position on a screen on the basis of a prescribed parameter and uses image projection means to project the converted data. The image data are polarized through polarization means so that video lights projected by the two image projectors reach different polarization states. COPYRIGHT: (C)2006,JPO&NCIPI
