Method and display for showing a stereoscopic image

摘要

A method of generating stereoscopic images and an autostereoscopic system are introduced. Stereoscopic images are obtained by generating, on a screen, a first image having a pattern comprising alternating columns of N left-image pixels or sub-pixels and of N right-image pixels or sub-pixels and a second image having a reversed pattern from the pattern of the first image. A parallel-strip barrier has alternating strips for blocking alternating columns of the first and second images. A tracking system provides position information related to a viewer of the stereoscopic image. A controller shifts to the left or to the right, in relation to the strips of the barrier, the image columns by a number of image pixels or sub-pixels as a function of the position of the viewer.

1. A method for displaying a stereoscopic image, comprising:
generating a first image having a pattern comprising alternating columns of N left-image pixels or sub-pixels and of N right-image pixels or sub-pixels; generating a second image having a reversed pattern from the pattern of the first image; blocking alternating columns of the first and second images in alternating strips of a parallel-strip barrier; and shifting to the left or to the right, in relation to the strips of the barrier, the patterns of the first and second images by a number of image pixels or sub-pixels as a function of a position of a viewer of the stereoscopic image.
