Structure of three-dimensional image data, method of recording three-dimensional image data, and method of displaying and reproducing three-dimensional image data
First Claim
1. A structure of three-dimensional image data for a three-dimensional image display apparatus,said the apparatus displaying a three-dimensional image in a viewing area by providing parallaxes in a horizontal direction and not in a vertical direction, and comprising:
- a display section having a display surface on which pixels are arranged in the horizontal direction at a first horizontal pitch to display a parallax synthetic image for three-dimensional display; and
a parallax barrier placed opposite the display surface and having linear optical openings arranged in the horizontal direction at a second horizontal pitch that is n (an integer) times as large as the first horizontal pitch, the parallax barrier parallelizing and directing rays from every n pixels arranged on the display surface along the horizontal direction, toward the viewing area;
said structure of three-dimensional image data comprising data on n or more parallax component images in each of which pixel columns allowing the pixels to generate parallel rays in the same parallax direction in the viewing area are accumulated, the parallax component images having different numbers of horizontal pixels, and every n connected images each obtained by combining one or more parallax component images corresponding to n-th adjacent parallax directions being converted into a parallax synthetic image, the connected images having substantially the same number of vertical pixels and substantially the same number of horizontal pixels.

Abstract
An apparatus displaying a three-dimensional image is provided with a parallax barrier having optical openings arranged at a horizontal pitch n times as large as that of pixels arranged on a display surface. The parallax barrier reproduces rays from every n pixels on the display surface in a horizontal direction and no vertical parallaxes is displayed in a viewing area. Image data for a three-dimensional image is processed so as to be recorded in an efficient saving format which minimizes the degradation of image quality while accomplishing a high compression rate. Image data from a set of pixels constituting parallel rays in the same parallax direction are accumulated to obtain more than n parallax component images. Parallax component images corresponding to n-th adjacent parallax directions are combined together and thus converted into n connected images having the same numbers of vertical and horizontal pixels.
