Patent

CA 2631878

There is disclosed a method of forming a securitized image comprising: obtaining a host image which is to be visible to an observer, obtaining a latent image to be concealed within the host image, adjusting the saturation of regions of at least one of the host image and the latent image such that when the latent image and the host image as adjusted are subsequently combined, the saturation of the combined regions will more closely approximate the saturation of corresponding regions of the original host image; and combining the latent image, and host image as adjusted to form a securitized image.

L'invention porte sur un procédé de formation d'une image sécurisée consistant: à obtenir une image hôte devant être vue par un observateur; à obtenir une image latente devant être cachée dans l'image hôte; à régler la saturation de zones d'au moins l'image hôte ou l'image latente, de manière à ce que elles se combinent après le réglage, la saturation des zones combinées approchant de très près celle de l'image hôte originale; et à combiner l'image latente et l'image hôte réglées pour former une image sécurisée.
