METHOD FOR THE PRODUCTION OF AN IRIDESCENT IMAGE, THE RESULTING IMAGE, DEVICE COMPRISING SAME AND ASSOCIATED PROGRAM

摘要

The invention relates to a method for the production of an iridescent image (II) from a reference image (IR), said iridescent image (II) comprising an optical selector (SO) selected from the group containing an array of cylindrical lenses, an array of spherical lenses and a parallax barrier. The method comprises the following steps consisting in: 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 a function of the values of the corresponding pixels in the reference image (IR); and associating the thus created dispersed image (ID) with the optical selector (SO). The invention also relates to the iridescent dispersed images obtained using such a method, to a device comprising said images and to an associated program.
