First Claim
1. An assembly for displaying an interlaced image, comprising:
- an interlaced image comprising sets of elongate image elements; and
a lens array comprising a first side proximate the interlaced image and a second side comprising a plurality of lens sets, wherein each of the lens sets is paired with one of the sets of the image elements and each of the lens sets comprises a plurality of elongate lenses that are each mapped to a subset of the image elements in the corresponding paired set of the image elements and that are arranged in adjacent pairs to form a plurality of dual lens structures.

Abstract
An assembly for displaying an interlaced image. The assembly includes an interlaced image, which may be digitally or web printed for example, with sets of elongate image elements or slices. A lens arrays is provided with a first side proximate the interlaced image such as a planar surface and a second side distal the image with numerous lens sets. Each of the lens sets is paired with one of the sets of the image elements and includes a number of linear or elongate lenses that are each mapped to one to three image elements. The lenses are each configured to focus light from the subset of image elements to a viewer along a focus direction or line. The lenses are configured to provide a lens-specific viewing angle with a focus line, and the focus line to the paired image element subset differs from other lenses or is unique.

9. An image display apparatus, comprising:
-
an interlaced image comprising a plurality of image elements each having a predefined width; and a lens substrate with a planar side proximate to the interlaced image and a lens side opposite the planar side, wherein the lens side comprises a plurality of lens microstructures each comprising a plurality of lenses that are each paired to one of the image elements to focus light passing through the lens substrate to about the predefined width and onto the paired one of the image elements, the lenses in each of the lens microstructures being arranged in dual lens structures comprising a first lens and second lens each distributing light from the paired one of the image elements at first and second viewing angles having equal magnitude but opposite sign as measured from a plane passing between the first and second lenses. - View Dependent Claims (10, 11, 12, 13, 14)

15. An image display assembly comprising:
-
an interlaced image including sets of image slices, comprising; a lens array comprising a substrate of a material that is at least translucent to light and with a first surface adjacent the interlaced image and a second surface comprising a plurality of lens microstructures, wherein each lens microstructure comprises; a first set of elongate lenses, wherein the lenses of the first set each have a first focus direction at a first angle relative to a plane perpendicular to the lens microstructure; and a second set of elongate lenses positioned adjacent the first set of elongate lenses and extending parallel to the extending parallel to the first set of elongate lenses, wherein the lenses of the second set each have a second focus direction at a second angle relative to a plane perpendicular to the lens microstructure that differs from the first angle; wherein each set of the image slices is paired with one of the lens microstructures. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22)
