Abstract

Se describe un método de fabricación de un dispositivo de seguridad, que comprende: a) proporcionar un mapa de profundidad de una macroimagen que representa un objeto tridimensional, el mapa de profundidad que representa la profundidad de cada parte del objeto tridimensional con relación a un plano de referencia por medio de diferentes colores y/o diferentes tonos de un color; b) segmentar el mapa de profundidad en una pluralidad de regiones basado en los colores y/o tonos del mapa de profundidad, cada región que comprende esa(s) parte(s) del mapa de profundidad que tiene(n) un color o valor tonal dentro de un intervalo predeterminado respectivo; c) para cada región, crear una matriz de elementos de microimagen respectiva, los elementos de microimagen que forman la matriz de elementos de microimagen que se disponen en una cuadrícula regular en una o dos dimensiones con un paso y orientación que son constantes en toda la región, la periferia de la matriz de elementos de microimagen que coincide sustancialmente con la de la región, la pluralidad resultante de matrices de elementos de microimagen que se disponen entre sí en las posiciones de las regiones respectivas en el mapa de profundidad para formar una primera capa de imagen; y d) proporcionar una matriz de elementos de muestreo de un paso y orientación predeterminados, la matriz de elementos de muestreo que se superpone a la pluralidad de matrices de elementos de microimagen, en donde los pasos de la matriz de elementos de muestreo y de las matrices de elementos de microimagen y sus ubicaciones relativas son tales que la matriz de elementos de muestreo coopera con cada una de las matrices de elementos de microimagen para generar versiones ampliadas de los elementos de microimagen en cada región debido al efecto moiré. El paso y/o la orientación de cada matriz de elementos de microimagen respectiva es diferente, y se configura de manera que las versiones ampliadas de los elementos de microimagen generados en cualquiera de las regiones tienen una profundidad aparente diferente con relación a las generadas en la(s) otra(s) región(es), para así formar una representación tridimensional de la macroimagen.
