A lenticular lens array (400) for creating a visual effect for an image viewed through the lenticular lens array comprises a plurality of lenticules (402, 404, 406) (402a, 404a, 406a) disposed adjacent to each other. Each lenticule comprises a lenticular lens element on one side and a substantially flat surface (407) on an opposite side. Each lenticular lens element has a vertex and a cross section comprising a portion of an elliptical shape (408). Alternatively, the cross section can comprise a major axis disposed substantially perpendicular to the substantially flat surface of each respective lenticular lens element. The vertex of each respective lenticular lens element lies substantially along the major axis of the elliptical shape.

Cette invention concerne une mosaïque de lentilles réticulaires (400) permettant de créer un effet visuel pour une image observée au travers de ladite mosaïque, qui comprend une pluralité de lenticules (402, 404, 406) (402a, 404a, 406a) disposés côte à côte. Chaque lenticule comprend un élément de lentille lenticulaire sur un côté et une surface sensiblement plate (407) sur le côté opposé. Chaque élément de lentille lenticulaire comporte un vertex et une section en coupe comportant une partie de forme elliptique (408). En variante, la section en coupe peut présenter un axe principal en gros perpendiculaire à la surface sensiblement plate de chacun des éléments de lentille lenticulaire. Le vertex de chacun de ces éléments se situe sensiblement le long de l'axe principal de la forme elliptique.
