Method for the production of an iridescent image (II) from a reference image (IR) is described. The iridescent image (II) comprises an optical selector (SO) selected from an array of cylindrical lenses, an array of spherical lenses and a parallax barrier. The method includes creating a period adapted to the optical selector (SO) and to the reproduction system used; creating a periodic image (IP) filled in a repetitive manner according to said period; creating a dispersed image by applying a dispersion filter to the periodic image (IP), in which the geometric position of the pixels of the periodic image (IP) is modified as function of the values of the corresponding pixels in the reference image (IR); and associating the created dispersed image (ID) with the optical selector (SO). The invention also relates to the iridescent dispersed images obtained using the method, a device comprising said images and an associated program. |
