Abstract:
1. A parallax barrier for an autostereoscopic display wherein the parallax barrier for an autostereoscopic display is provided with a distance Z from an image display surface of a display on which a plurality of pixels each having horizontally arranged three subpixels displaying R, G, and B are arranged in horizontal and vertical directions, values relating to sizes and arrangements of a plurality of visible light transmitting sections and a value of the distance Z are calculated and designed based on a predetermined designing condition, and in autostereoscopic viewing under a condition in which: an average number of subpixels in a horizontal direction constituting pixels for three-dimensional display for one viewpoint of an autostereoscopic video image created from video images of a plurality of viewpoints is defined as α; a width of subpixels constituting the display is defined as Ph; a distance between centers of pixels for three-dimensional display that display video images of neighboring viewpoints is defined as αPh; a distance between pupils of left and right eyes of a subject person of video image presentation is defined as W; and a number of viewpoints of the video images for creating the autostereoscopic video image is defined as N, and in a design condition in which: a most appropriate three-dimensionally viewable position is preset and a distance from such a position to the parallax barrier is defined as L a diagonal moire cancelling position is preset and a distance from such a position to the parallax barrier is defined as L the parallax barrier is designed by determining a value of the distance Z from the image display surface of the display to the parallax barrier by a following function (1); and determining a value of an interval Hh between a plurality of horizontally abutting visible light transmitting sections constituting the parallax barrier by a following function (2):
