Abstract: The invention relates to a method for producing a series of modified images intended for forming an iridescent image, using at least one reference image, characterised by including steps of creating a color pallet (P); creating a series of at least two modified reference images (IRM0, IRM1, IRM2, IRMn, etc.), in which the colors of said at least one reference image (IR) are replaced with the colors of the pallet by applying, before or between each new modified reference image (IRM), a circular shift to the colors of the pallet. The invention also relates to the inter-laced, iridescent, 3-D images obtained using such a method, as well as to a device including such an interlaced image and an associated program.

Abstract: 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.

Abstract: The invention relates to a method for producing a series of modified images intended for forming an iridescent image, using at least one reference image, characterised by including steps of creating a colour pallet (P); creating a series of at least two modified reference images (IRMO, IRMI, IRM2, IRMn, etc.), in which the colours of said at least one reference image (IR) are replaced with the colours of the pallet by applying, before or between each new modified reference image (IRM), a circular shift to the colours of the pallet. The invention also relates to the inter-laced, iridescent, 3-D images obtained using such a method, as well as to a device including such an interlaced image and an associated program.
