Definitions

  • a higher number of views corresponds to a denser gradation in spatial depth or in perspective, so that the three-dimensional impression is improved.
  • the change of view is also less erratic.
  • the number of image display elements on which partial information from different views is displayed at the same time depends both on the number of image display elements available and on the number of views to be displayed.
  • a filter array disk for a specific horizontal picture element period and then to use it on imagers which differ in the parameters.
  • 1 2 views can be periodically summarized on eight image display elements.
  • the partial information assigned to an image reproduction element ⁇ should come from the views from the same grid point (i, j).
  • Each image display element is assigned an average of 1, 5 pieces of information.
  • the elements can now be determined according to equation (2), some of which are shown in FIG. 3 for different tripi (c, i, j).
  • An image display element represents one box each. Entered in the boxes are the numbers of the views from which the partial information has been assigned to the image display element, with the respective weighting as a factor.
  • the wavelength filter array shown is a typical one Version made of a film printed with transparent and opaque filters, each marked as white or black. Colored wavelength filters would also be conceivable, as well as a wavelength filter array provided with a second control, in which the transparency wavelength ranges can be changed by means of the second control.
  • the height and width of the filter elements essentially correspond to the dimensions of the image display elements, the width of the filter elements is denoted by p t .

Abstract

L'invention concerne un procédé de représentation spatiale d'une scène ou d'un objet, sachant que plusieurs vues de la scène ou de l'objet sont décomposées en données partielles pouvant être reproduites de manière optiquement perceptbile sur des éléments de reproduction d'images. Des éléments de reproduction d'images adjacents émettent une lumière de différentes longueurs d'ondes ou plages de longueurs d'ondes. Pour la lumière, on prend un dispositif de propagation qui, au moyen de filtres de longueurs d'ondes, permet à un observateur de percevoir d'un oeil principalement des informations partielles d'une première sélection et de l'autre oeil principalement des informations partielles d'une deuxième sélection. L'invention vise à améliorer la qualité de la représentation spatiale. Selon un tel procédé, des informations partielles d'au moins deux projections différentes sont associées simultanément à au moins un élément de reproduction d'images. L'association est effectuée de telle manière que les longueurs d'ondes des informations partielles coïncident systématiquement avec la longueur d'onde de la lumière émise par l'élément de reproduction d'images associé ou se situent dans la plage de longueurs d'ondes de la lumière émise par l'élément de reproduction d'images associé.
