Abstract (en)
[origin: WO2019175514A1] The invention relates to a document (2) capable of generating a colour image (6), comprising: a set of pixels (20) printed on or in a substrate (2), each pixel (20) forming a pattern comprising an arrangement of sub-pixels (22) of at least two different colours; and an array of lenses (LN) disposed facing the set of pixels so as to generate the colour image (6) by focusing or diverging an incident light through the lenses on at least one part of the sub-pixels (22), each lens (LN) being positioned, relative to an associated pixel (20) located opposite, to focus or diverge the incident light on at least one of the sub-pixels (22) of said associated pixel so as to modify the contribution of the respective colours of the sub-pixels (22) of the associated pixel (20), in a region of the colour image (6) generated through said lens, relative to the pattern intrinsically formed by the associated pixel (20) independently of said lens (LN).
