Abstract

The invention relates to an autostereoscopic screen for the simultaneous reproduction of several different images with a pixel matrix (21) on which a multitude of at least six or at least eight disjoint subsets of pixels (25) are defined such that each of the subsets forms a family of parallel strips of pixels (25) with an optical element (22) which is arranged in front of or behind the pixel matrix (21) and which has a grating like structure orientated parallel to the strips so that at a nominal distance (Dn) in front of the screen and set by a geometry of the screen viewing zones (26) are defined such that each of the viewing zones (26) is assigned to exactly one of the subsets and the light departing or transmitted from each of the subsets of pixels (25) is deflected into the viewing zone assigned to this subset. Moreover the screen comprises a control unit (23) for activating the pixel matrix (21) in dependence on image data (24) which define a 3D image. Thereby the control unit (23) is configured for activating the pixel matrix (21 ) for an autostereoscopic viewing of the 3D image from a viewing distance (D) in front of the screen said distance being different to the nominal distance (Dn). For this a plurality smaller compared to the mentioned multitude of at least three or at least four disjoint part sets of the pixels (25) of the pixel matrix (21) which are different to the mentioned subsets are defined in a manner such that each of the part sets forms a family of parallel bands wherein each of these bands or each of the majority of the bands or each of at least some of the bands is formed by way of grouping together at least two of the mentioned strips of pixels (25) and wherein the bands of the different part sets cyclically alternate in the horizontal direction. A number of stereoscopic half images corresponding to the mentioned plurality which are defined by the image data (24) and complement one another in pairs into a stereo image perceivable as a 3D image are reproduced by way of the pixels (25) of the pixel matrix (21) in a manner such that in each case one of the stereoscopic half images is reproduced on each of the thus defined part sets. The invention also relates to a corresponding method for reproducing 3D images.
