Abstract

Un dispositivo de seguridad (100, 900) incluye una disposición de elementos de enfoque de iconos de imagen (120, 605, 705) donde cada elemento de enfoque de iconos de imagen de la disposición de elementos de enfoque de iconos de imagen está asociado con una trayectoria focal. El dispositivo incluye adicionalmente una capa de iconos de imagen donde uno o más iconos de imagen (110a, 909) se asocian con un primer color característico y uno o más iconos de imagen (110b, 911) se asocian con un segundo color característico, y una o más regiones entre iconos de imagen que comprende un volumen de material sustancialmente incoloro. En un primer ángulo de visión, un color es visible a través de cada elemento de enfoque de iconos de imagen y el color visible a través de cada elemento de enfoque de iconos de imagen en el primer ángulo de visión se basa en uno o más del primer color característico, el segundo color característico o el material sustancialmente incoloro.
