Patent number: 10780728Abstract: A secure article including a revelation screen and a combined image, or a set comprising a secure article and another object. The secure article including one of the revelation screen and the combined image and the object comprising or making up the other of the revelation screen and the combined image. The combined image including a plurality of overlapping images. The combined image including a periodic alternation of overlapping image elements in a first direction. The revelation screen including a masking screen element alternating periodically with a non-masking screen element in a second direction. The size of the non-masking screen elements in the second direction is greater than the size, in the first direction, of at least one element of overlapping images, the revelation screen making it possible to observe various revealed images by moving the revelation screen in relation to the combined image and/or by changing the observation angle.Type: GrantFiled: December 23, 2016Date of Patent: September 22, 2020Assignee: OBERTHUR FIDUCIAIRE SASInventor: Philippe Dietemann
