20100046069 | METHOD AND ARRANGEMENT FOR THREE-DIMENSIONAL REPRESENTATION - The invention relates to the field of spatial representation, particularly to images which are spatially perceivable for simultaneous multiple viewers without auxiliary devices so-called autostereoscopic visualization. The invention addresses the problem of creating a form of autostereoscopic representation based on barrier technology in order to achieve an improved perceptibility for multiple simultaneous viewers. This problem is solved by a method for spatial representation wherein image section data of different viewpoints A(k), where k=1, . . . , n and n=6 or n=7, are made visible on a grid of image elements x(i,j), and at least one parallax barrier screen containing alternating opaque and transparent sections is placed at a distance before or behind the grid of image elements x(i,j). The transparent sections substantially correspond to straight bordered lines which, during the parallel projection of parallax barrier screens onto the grid of image elements x(i,j), are inclined to at least 21 degrees with respect to the vertical direction of the grid of image elements x(i,j) and, furthermore, each have the width of at least 1.9 image elements x(i,j) in the horizontal direction of the grid of image elements x(i,j). | 02-25-2010 |
20100103334 | METHOD FOR THE ORIENTATION OF A PARALLAX BARRIER SCREEN ON A DISPLAY SCREEN - A method for the orientation of a parallax barrier screen on a display screen with pixels x(ij) in a pattern of rows (i) and columns (j) for the production of a display screen for three-dimensional representation. Particularly, a test image is presented comprising various views A(k) where k=1, . . . , n and n=6 or n=7, wherein the test image comprises at least two first straight lines having two different directions of extension from one another, said lines being disposed in different horizontal positions in the n=6 or n=7 views A(k), wherein the test image comprises at least two second straight lines that are each oriented parallel to one of the first straight lines and that are disposed at least at the same horizontal positions in the n=6 or n=7 views A(k).

20100220325 | METHOD FOR ORIENTING AN OPTICAL ELEMENT ON A SCREEN - The invention relates to a method for orienting an optical element (e. g. a parallax barrier screen or lenticular screen) on a screen comprising pixels x(i, j) in a raster composed of lines (i) and columns (j) in order to produce a screen for three-dimensional representation. In said method, especially a test pattern is presented which consists of various views A(k), wherein k=n, and n>1. The test pattern comprises at least two first straight lines that are located in different horizontal positions in the n>1 views A(k) as well as at least two second straight lines which each extend parallel to one of the first straight lines and are located in at least the same horizontal positions in the n>1 views A(k). The method according to the invention can be carried out quickly and with high accuracy and is therefore suitable for industrial use to produce screens for three-dimensional representation. | 09-02-2010 |
20100238275 | Method for Shortening or Lengthening a Viewing Distance between a Viewer and an Arrangement for Spatially Perceptible Display - The invention relates to the field of spatial representation, in particular to the spatially perceptible representation without auxiliary means for a plurality of observers at a time, the so-called autostereoscopic visualization. It is the object of the invention to create a possibility for autostereoscopic representation, allowing an adjustment of the observation distance independently of constraints for the configuration of the distance from the image display device to the optical element, for example a barrier or lenticular lens. This object is achieved by a method for spatial representation, in which partial image information of different views A(k), wherein k=1, . . . ,n and n>=2, is visualized on a grid ( | 09-23-2010 |
