Viewing Zones of IP and Other Multi-view Image Methods

Abstract

Multi-view, three-dimensional imaging methods use a different set of view images (multi-view) to create three-dimensional images. In these methods, the images can be projected with an array of projectors (projection type) or displayed on a display panel (contact type). However, the methods are basically based on both binocular and motion parallaxes as their depth cue. For the parallaxes, the viewing zone should be divided into many viewing regions and each of these regions allows viewers to perceive an individual view image or a mixed image composed of parts from more than two different view images in a multi-view image set. The number of viewing regions and the composition of the image at each of the regions can be predicted by the number of different view images in the multi-view image and of pixels in a pixel cell. When the pixel cell is composed of non-integer number pixels, more regions are created than an integer number and the compositions become more complicated. This is because a number of pixel cells are involved in defining the viewing regions.
