Abstract (en)
[origin: WO2008061511A1] The invention relates to a stereo projection system and a method for generating an optically perceptible three-dimensional pictorial reproduction. For each of the two perspective partial images (left or right) of the stereo image, regions of the visible spectrum, which are defined differently by colour filters, are masked in such a way that a plurality of only limited spectral intervals is transmitted in the region of the colour perception blue (B), green (G), and red (R). The position of the transmitted intervals is selected differently for the two perspective partial images. The number of transmitted intervals for the two perspective partial images is, according to the invention, selected as lower than 6 (b) either for the image generation or for the image detection by the stereo glasses, and equal to 6 (a). In the event of a reduced number (b), at least one transmitted interval for one of the perspective partial images is selected in transmission in the region of two colour perceptions blue (B), green (G) or red (R), and created by right-left permutation and subsequent combination with an adjacent interval. According to the permutated intervals, the associated image data is analogously permutated. In this way, the cost of the filters, especially interference filters for the stereo projection system or for the method for producing an optically perceptible, three-dimensional pictorial reproduction, is significantly reduced without considerably affecting the reproduction quality. The unpleasant flickering is also reduced.
