Eye-glasses for viewing stereoscopic images or a perspective sub-image of a stereoscopic image, comprising at least one interference filter that has at least one photosensitive polymer film and at least two separated filter regions, said filter regions being superimposed along at least one normal line that stands vertically on a first outer surface of the interference filter, between a first point at which the normal line pierces the first outer surface and a second point at which the normal line pierces a second outer surface of the interference filter after having passed through said interference filter proceeding from the first point, and said filter regions being, along said normal line, at least substantially impermeable to a respective predetermined wavelength interval of the electromagnetic spectrum.

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.

System for reproducing stereographic images

A device for projecting a color image upon a screen, including color image recording and color image reproduction with an enhanced color reproduction trueness in comparison to conventional processes. In the device two images are recorded in parallel, which separately detect the shorter and the longer wavelength parts of the individual principle color spectral regions. In image reproduction six primary valences are produced, which respectively comprise the image information of the shorter and the longer wavelength parts of each of the individual principle color spectral regions. In an alternative embodiment the device produces a full color, stereoscopic image reproduction, in which the three primary valences of the respective shorter wave part encode a stereoscopic half image and the three primary valences of the respective longer wavelength part encode the other stereoscopic half image.
