Claim:
A method for an autostereoscopic presentation of image information on a matrix screen having a barrier raster having barrier elements being arranged in parallel to said matrix screen, the method comprising: assigning subpixel groups to said barrier elements, said subpixel groups being combined to form image lines on the matrix screen, each of the subpixel groups having n subpixels including a subpixel reserve and being variable in their intensity, in which a screened subpixel excerpt from a right and from a left stereo image view being displayed on the subpixels are fed to the right and to the left eye of an observer via the barrier raster in a correct allocation, tracking at least horizontally the image information relative to the matrix screen with respect to an initial position in the center of the matrix screen by proportionally shifting intensity focuses of the subpixel group and by re-allocating image information to the subpixels becoming visible to the respective other eye when detected horizontal parallel alterations of a head position of the observer, initially forming intensity focuses of the subpixel groups depending on the position of the observer, and reducing the total intensity of the matrix screen to at least a value of (n−1)/n of the total intensity of the matrix screen, and when detected parallel changes of the observer's head position relative to the matrix screen, subsequently laterally shifting in a continuous manner said intensity focuses of the subpixel groups, while maintaining the reduced total intensity within the subpixel groups in the image lines; widening the intensity focuses for an approach and compressing the intensity focuses for a more distance position of the observer's head relative to the matrix screen, the widening and, the compressing being inversely proportional when the barrier raster is arranged in front of the matrix screen in the direction of viewing and directly proportional when the barrier raster is arranged behind the matrix screen in the direction of viewing in the case of detected changes of the distance of the observer's head position relative to the matrix screen increasing towards the lateral edges of the matrix screen; in which the shifting, the widening or the compressing of the intensity focuses of the subpixel groups takes place by changing the intensity of the subpixels accordingly via directly adjacent subpixels in the image lines, depending upon the size of the parallel change and distance change, even across boundaries between the adjacent subpixel groups of differing stereo image views and released subpixels involved in the adjacent subpixel group of the respective other stereo image view; and wherein current head position of the observer is determined by involving a tracking method, in particular a video-based tracking method for locating head and eye details of the observer, and a recording setting for the stereo image views is carried out dynamically depending on current position of eyes determined by the tracking method.
