Abstract:
1. A method for the autostereoscopic representation of image information on a matrix screen, on which a plurality of image points is formed using a subpixel group having a plurality of subpixels being modifiable in their intensity and being positioned in rows and columns, wherein two stereoscopic fields are imaged on one of two subgroups each of the image points, and wherein light emanating from the two subgroups of image points is guided through a barrier raster into two adjacent viewing zones such that the light emanating from the image points of a first one of the two subgroups is incident into a left viewing zone for a left eye, and the light emanating from the image points of a second one of the two subgroups is incident into a right viewing zone for a right eye of a viewer, wherein a change of a head position of the viewer is further detected, and activation of the subpixels is adapted to the change of the head position, wherein said subpixels within each of the image points are activated with a line-by-line subpixel-dependently weighed intensity in addition to the image information such that an intensity centroid within the respective image point and thus a centroid of a lateral intensity distribution of the light emanating from this image point can laterally be shifted in the corresponding viewing zone by varying the weighting, wherein the intensity centroids within the image points are shifted upon a change of a viewing distance between the head position and matrix screen by matching the weighting of the intensities such that a lateral distance between said intensity centroid within an image point of said first subgroup and said intensity centroid within a nearest image point of said second subgroup is varied and such that a lateral distance between the centroid of the intensity distributions in the left viewing zone and the centroid of the intensity distributions in the right viewing zone in a viewing plane varying with the head position remains constant.
