Special features of stereo visualization in multichannel autostereoscopic display from 4D-Vision

Our company 4D-Vision develops technology based on the wave length selective filter array which allows to observe the stereo-images and animations in TFT or plasma displays of any size, from 3.9 to 50 inches and even more and at relatively low cost. The other advantage of our original technology is that the stereo-images may be viewed on our 3D displays by many users simultaneously and without having to use any additional viewing aids. In this paper we present in matrix form the different types of the stereo-image encoding which may be realized in our 3D display. In particular, we show that the colour stereo-image on our 3D display may be obtained also from the set of the 2D gray scaled images. We present also the results of the investigation of stability of the stereo-image with respect to the definite perturbations dependent on an angle between neighbour perspectives. The general relations, allowing to evaluate the distribution of the 2D images in one stereo-image are also presented. Some of them were already realized in our 3D display. At this time 4D-Vision manufactures 3D-displays using up to 40 channels for the stereo-image representation. We show, that the presented results may be also used in stereo projection devices, based on 4D-Vision technology.
