An image acquisition device is provided for use in determining whether a test object is an authentic object having an authentication image applied to an authentication image area thereof. The authentication image includes indicia formed based on authentication parameters. The image acquisition device comprises an image capture arrangement configured for capturing a digital image of a target area of a test object. The image acquisition device further comprises a data processor having an image processing portion configured for receiving and processing the digital image to produce a processing result. The processing result may be established at least in part using one or more of the authentication parameters.

La présente invention concerne un dispositif dacquisition dimage à utiliser pour déterminer si un objet dessai est un objet authentique ayant une image dauthentification appliquée à une zone dimage dauthentification de celui-ci. Limage dauthentification comprend des indices formés à partir de paramètres dauthentification. Le dispositif dacquisition dimage comprend un agencement de capture dimage configuré pour capturer une image numérique dune zone cible dun objet dessai. Le dispositif dacquisition dimage comprend en outre un processeur de données comportant une partie de traitement dimage configurée pour recevoir et traiter limage numérique de manière à produire un résultat de traitement. Le résultat de traitement peut être établi au moins en partie à laide dun ou de plusieurs des paramètres dauthentification.
