Identification document with three dimensional image of bearer
View Patent ↗An identification document includes a lens system and a specially prepared photo of a document bearer. The lens system and the specially prepared photo cooperate to create a three dimensional photo effect. The document includes two or more document layers. There is a lens structure in one of the document layers, and it includes lens elements. A photo is printed on one or more of the document layers. The photo depicts the document bearer, and includes two or more separate images of the bearer from different perspectives. Parts of the separate images are interleaved together into sets, and the sets are positioned relative to corresponding lens elements of the lens structure. These sets include parts of the separate images such that when viewed through the lens structure, the parts are viewed simultaneously making the subject appear three-dimensional to a viewer.
1. In a method of producing an identification document that includes:
capturing an image of a person; and
printing image data so that the image data is conveyed by the document, wherein the image data corresponds to the captured image;
an improvement comprising:
producing a 3D representation from a single captured 2D image;
from said 3D representation, generating at least two 2D images; and
printing, in interleaved fashion, image data from said generated 2D images so that the image data is conveyed by the identification document.
2. The method of claim 1 that includes constructing said identification document of laminated layers, wherein said printing and said constructing are arranged so that delamination of the document causes evidence of tampering to appear in said printed image data.
3. The method of claim 1 in which said printing includes printing data from a first of said generated images on a first layer, and printing data from a second of said generated images on a second layer, and in which the method includes laminating said printed layers.
4. The method of claim 1 that includes forming a lenticular lens array with the document, wherein first and second of said generated 2D images yield a 3D impression when viewed by a human viewer through said lens array.
5. The method of claim 1 that includes forming a lenticular lens array with the document, said forming including embossing a laminate layer.
6. The method of claim 1 that includes forming a lenticular lens array with the document, said forming including burying beads in a laminate construction.
7. The method of claim 1 that includes forming a lenticular lens array with the document, said forming including shaping a surface of a laminate layer, and coating said surface with a material having a different refractive index prior to applying adhesive to said laminate layer.
8. In a method of producing an identification document that includes:
capturing an image of a person; and
printing image data so that the image data is conveyed by the document, the image data corresponding to the captured image;
an improvement comprising:
positioning the person within view of first and second spaced-apart locations;
capturing first and second images of the person from perspectives of the first and second locations; and
printing, in interleaved fashion, image data from said first and second images so that the image data is conveyed by the identification document.
9. The method of claim 8 that includes constructing the identification document of laminated layers, wherein said printing and said constructing are arranged so that delamination of the document causes evidence of tampering to appear in the printed image data.
10. The method of claim 8 in which said printing includes printing data from the first image on a first layer, and printing data from the second image on a second layer, and in which the method includes laminating the printed layers.
11. The method of claim 8 that includes forming a lenticular lens array with the document, wherein the first and second images yield a 3D impression when viewed by a human viewer through the lens array.
12. The method of claim 8 that includes forming a lenticular lens array with the document, said forming including embossing a laminate layer.
13. The method of claim 8 that includes forming a lenticular lens array with the document, said forming including burying beads in a laminate construction.
14. The method of claim 8 that includes forming a lenticular lens array with the document, said forming including shaping a surface of a laminate layer, and coating said surface with a material having a different refractive index prior to applying adhesive to said laminate layer.
