Abstract: The method and device of the invention includes the storage of a plurality of data or digital information blocks, corresponding to the images to be exhibited. Each one of these blocks is processed by the device, which has the means to read the data blocks, said data of each block being then divided in n vertical bands, n being equal to the total number of cylinder lenses. Later, data corresponding to each band are divided in m sub-bands, m being equal to the number of images to be included in the graphic pattern. Only the data belonging to the sub-bands of the order mentioned below, shall be kept:k.sub.1.sup.m +(j.sub.1.sup.n -1).times.mk being the k-times image and j the j-times band, with which an intermediate digital block is obtained for each initial data block corresponding to each initial image.
