Method and devices for the generation of printed images which define patterns to be used in graphic information

A method for the generation of printed images which define patterns to be used in graphic information exhibiting panels of the type made up of a plurality of cylinder, converging lenses arranged parallel each other, comprising the steps of:

• a) storing of one or more data or digital information blocks, corresponding to the corresponding images intended to be exhibited;
• each one of these digital data blocks being processed by submitting them at least to the following operations:
• a.a) reading of a data block or digital file;
• a.b) division of the data of the corresponding block or digital file in n vertical bands, n being equal to the number of cylinder lenses which the exhibitor shall have;
• a.c) division of the data of the corresponding block or digital file of each one of the n bands in m sub-bands, m being the number of different images to be included;
• a.d) to keep only the data belonging to the sub-bands belonging to the sub-band of the order:
• k.sub.1.sup.m +(j.sub.1.sup.n -1).times.m
• where k is the k-times image and i the j-times band, thus a corresponding intermediate digital block being obtained, which contains sub-bands which have been "picked out" from the corresponding initial data block;
• a.e) to repeat the stages a.a) through a.d) for each image, so that the corresponding intermediate digital blocks are obtained;
• a.f) obtaining of the corresponding individual terminal data blocks, which contain only information corresponding to the medium lines of each sub-band selected in the corresponding intermediate digital block of a width of one pixel, and which keeps the memory address (position) of the corresponding sub-band;
• a.g) merger or integration of each individual terminal data block, keeping their relative addresses, and juxtaposing the different sub-bands in just one pattern block, which may be stored as graphic file for its later printing.
