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.

摘要： A security element (1) for a security paper, value document or the like, having a carrier (8) which has an areal region (3) which is divided into a multiplicity of pixels (4) which respectively includes at least one optically active facet (5), whereby the majority of the pixels (4) respectively have several of the optically active facets (5) of identical orientation per pixel (4), and the facets (5) are so oriented that the areal region (3) is perceptible to a viewer as an area that protrudes and/or recedes relative to its actual spatial form.
