Abstract
A method for displaying image information on an autostereoscopic screen that is suitable for simultaneous display of a plurality of views visible respectively from at least one of a plurality of laterally offset viewing zones. A first stereoscopic half-image and a second stereoscopic half-image, which are perceptible simultaneously and together produce a stereoimage, are reproduced on the screen such that the first stereoscopic half-image is visible from two laterally offset and respectively continuous regions, while the second stereoscopic half-image is visible from a stereozone which is situated between the two mentioned regions and is smaller than each of these two regions.
Claims15
A method for displaying image information on an autostereoscopic screen that is suitable for simultaneous display of a plurality of more than two views which are visible respectively from at least one of a plurality of laterally offset viewing zones, the method comprising:
- reproducing a first stereoscopic half-image on the screen such that the first stereoscopic half-image is visible from two laterally offset and respectively continuous regions;
- reproducing a second stereoscopic half-image on the screen such that the second stereoscopic half-image is visible from a stereozone that is disposed between the two laterally offset and respectively continuous regions and that is smaller than the two laterally offset and respectively continuous regions;
- wherein the first stereoscopic half-image and the second stereoscopic half-image are simultaneously perceptible and together produce a stereoimage.
An autostereoscopic screen configured to simultaneous display a plurality views which are visible respectively from at least one of a plurality of laterally offset viewing zones, the autostereoscopic screen comprising:
- a matrix screen with a large number of subpixels;
- a beam splitter grid configured to direct light emanating from the subpixels respectively into at least one of the plurality of laterally offset viewing zones;
- and
- a control unit for activating the subpixels of the matrix screen as a function of image information of a first stereoscopic half-image and of a second stereoscopic half-image;
- wherein the control unit is configured, in at least one possible operating mode, to apportion image information of the first stereoscopic half-image and the second stereoscopic half-image to the subpixels such that image points of the first stereoscopic half-image are reproduced on a larger number of subpixels than image points of the second stereoscopic half-image so that the first stereoscopic half-image is visible from two laterally offset and respectively continuous regions, while the second stereoscopic half-image is visible from a stereozone which is situated between the two mentioned regions and is smaller than each of these two laterally offset and respectively continuous regions.
