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. A method of producing an identification document comprising the steps of:
providing one or more image-bearing layers on the identification document;
positioning a person within view of first and second spaced-apart image capture locations;
capturing first and second images of the person from perspectives of the first and second image capture locations; and
laser engraving, in interleaved fashion, image data from said first and second images onto the one or more image-bearing layers so that the image data is conveyed by the identification document with a three dimensional effect.
2. The method of claim 1 in which the one or more image-bearing layers comprise a first and a second layer and wherein said laser engraving includes laser engraving data from the first image on the first layer and laser engraving data from the second image on the second layer, and further comprising laminating the laser engraved layers.
3. The method of claim 1 further comprising providing a lenticular lens array on the identification document over the interleaved image data and wherein the interleaved image data yields the three dimensional effect when viewed by a human viewer through the lens array.
4. The method of claim 3 wherein the lenticular lens array is formed by embossing a laminate layer of the identification document.
5. The method of claim 3 wherein the lenticular lens array is formed by burying beads in a laminate layer of the identification document.
6. The method of claim 3 wherein the lenticular lens array is formed by shaping a surface of a laminate layer, and coating said surface with a material having a different refractive index.
7. The method of claim 1 wherein the first and second images are captured by camera equipment.
8. The method of claim 7 where the camera equipment comprises 3D camera equipment.
9. The method of claim 1 further comprising capturing a third image of the person from a perspective different from the perspectives of the first and second image capture locations.
