Abstract
A system for reproducing stereographic images is provided that includes a display unit that has a pixel array for representing image data which reproduces the same when controlled with stereoscopic image data, and a light source for fully illuminating the pixel array. The system further includes a pair of glasses that are suitable to make the reproduced stereoscopic image data available to a wearer of the pair of glasses in an eye-selective manner. The display unit has at least one additional light source for fully illuminating the pixel array. Every light source is additionally configured to emit light in a plurality of narrow spectral ranges, thereby defining a color range, the spectral ranges of the light sources being orthogonal to each other. The system also includes a control unit that sequentially operates the light sources. The pair of glasses has optical glasses, spectral transmission ranges of which are orthogonal to each other and correspond to the spectral ranges of the light sources in such a manner as to allow the reproduction of stereographic images in a reliable and cost-effective manner.
