Abstract

L'invention concerne un appareil de formation d'images codées. Selon l'invention, une image d'un graphisme est brouillée à l'aide d'une caméra pseudoscopique. Le graphisme et l'obturateur focal de la caméra se déplacent simultanément par rapport à un objectif et un graticule si bien que l'image obtenue paraît incohérente à l'oeil nu. Elle peut être débrouillée par observation avec un graticule analogue à celui qui est utilisé pour le brouillage. Application au brouillage des documents pour leur protection contre les contrefaçons.
