DEPICTION ARRANGEMENT

摘要

The invention relates to a depiction arrangement for security papers, value documents, electronic display devices or other data carriers, having a grid image arrangement for depicting a target image (40) that is broken down into two or more partial target images (42, 44), having
a motif image that is subdivided into a plurality of periodically or at least locally periodically arranged cells (24) in each of which are arranged mapped regions of one or more of the partial target images (42, 44),a viewing grid (22), composed of a plurality of viewing grid elements, that, when the motif image is viewed, reconstructs the complete target image (40) from the mapped regions arranged in the cells (24),the motif image being, independently of the cell subdivision, split into at least first and second microinformation regions (60, 62) in which the cells each include different combinations of mapped regions of the partial target images (40, 42), and the microinformation regions (60, 62) being arranged in the shape of specified image motifs that exhibit information-bearing image patterns whose dimensions are below the resolution limit of the human eye.

主权项

1. A depiction arrangement for security papers, value documents, electronic display devices or other data carriers, comprising a grid image arrangement for depicting a target image that is broken down into two or more partial target images, said depiction arrangement comprising:
(a) a motif image that is subdivided into a plurality of periodically or at least locally periodically arranged cells in each of which are arranged mapped regions of one or more of the partial target images, (b) a viewing grid optically connectable to the motif image, said viewing grid composed of a plurality of viewing elements for viewing the motif image through the viewing grid, wherein the viewing grid, when the motif image is viewed through the viewing grid, reconstructs the complete target image from the mapped regions arranged in the cells,wherein the motif image, independently of the cell subdivision, is split and comprises at least first and second microinformation regions in which the cells each include different combinations of mapped regions of the partial target images, and wherein the microinformation regions are arranged in the shape of specified image motifs configured to exhibit information-bearing image patterns whose dimensions are below the resolution limit of the human eye;
wherein the depiction arrangement comprises a magnification arrangement selected from the group consisting of:
(i) a moiré magnification arrangement in which the mapped regions of the cells of the motif image each constitute scaled-down images of the partial target images, which are completely accommodated within one cell;(ii) a micro-optical moiré-type magnification arrangement in which the mapped regions of multiple spaced-apart cells of the motif image constitute in each case, taken together, a scaled-down image of one of the partial target images, whose dimension is larger than one cell of the motif image; and(iii) a modulo magnification arrangement in which the mapped regions of the cells of the motif image each constitute non-complete sections, configured to be mapped by a modulo operation, of one or more of the partial target images.
