Abstract
Abstract An integral image element, comprising: an integral lens sheet with opposed front and back surfaces, the front surface carrying convex surfaces of a plurality of lens elements; an integral image positioned behind the back surface; and a non-specular reflective layer positioned behind the integral image which layer reflects more than 80% of visible light reaching the reflective layer from in front of the layer, before penetrating the reflective layer a distance of 10 microns. A method of making the foregoing type of integral image element is also provided.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
74 words
An integral image element, comprising: an integral lens sheet with opposed front and back surfaces, the front surface carrying convex surfaces of a plurality of lens elements; an integral image positioned behind the back surface; and a non-specular reflective layer positioned behind the integral image which layer reflects more than 80% of visible light reaching the reflective layer from in front of the layer, before penetrating the reflective layer a distance of 8 microns.
Claim 2
Dependent Claim
74 words
An integral image element, comprising: an integral lens sheet with opposed front and back surfaces, the front surface carrying convex surfaces of a plurality of lens elements; an integral image positioned behind the back surface; and a non-specular reflective layer positioned behind the integral image which layer reflects more than 80% of visible light reaching the reflective layer from in front of the layer, before penetrating the reflective layer a distance of 8 microns.
Claim 3
Dependent Claim
24 words
An integral image element according to claim 1 wherein the integral lens sheet is a lenticular lens sheet with lenticules on the front surface.
Claim 4
Dependent Claim
19 words
An integral image element according to claim 2 wherein the reflective layer is positioned immediately adjacent the integral image.
Claim 5
Dependent Claim
16 words
An integral image element according to claim 1 wherein the reflective layer is a non-metallic layer.
Claim 6
Dependent Claim
16 words
An integral image element according to claim 1 wherein the integral image is a depth image.
Claim 7
Independent Claim
114 words
A method of exposing an integral imaging element having: an integral lens sheet with opposed front and back surfaces, the front surface carrying convex surfaces of a plurality of lens elements; and a light sensitive layer positioned behind the back surface; the method comprising the steps of: exposing the light sensitive layer with light from behind the back surface; processing the light sensitive layer to fix any image from exposure; and covering the processed light sensitive layer with a non-specular reflective layer positioned behind the integral image which layer reflects more than 80% of the visible light reaching the reflective layer from in front before penetrating the reflective layer a distance of 8 microns.
Claim 8
Independent Claim
114 words
A method of exposing an integral imaging element having: an integral lens sheet with opposed front and back surfaces, the front surface carrying convex surfaces of a plurality of lens elements; and a light sensitive layer positioned behind the back surface; the method comprising the steps of: exposing the light sensitive layer with light from behind the back surface; processing the light sensitive layer to fix any image from exposure; and covering the processed light sensitive layer with a non-specular reflective layer positioned behind the integral image which layer reflects more than 80% of the visible light reaching the reflective layer from in front before penetrating the reflective layer a distance of 8 microns.
Claim 9
Dependent Claim
22 words
A method according to claim 6 wherein the integral lens sheet is a lenticular lens sheet with lenticules on the front surface.
Claim 10
Dependent Claim
17 words
A method according to claim 7 wherein the refelective layer is positioned immediately adjacent the integral image.
Claim 11
Dependent Claim
14 words
A method according to claim 8 wherein the reflective layer is a non-metallic layer.
Claim 12
Dependent Claim
14 words
A method according to claim 8 wherein the integral image is a depth image.
Claim 13
Dependent Claim
55 words
A method according to claim 8 wherein, during the exposure step, the element additionally has an anti-halation layer on at least a portion of the front surface of the lens sheet which anti-halation layer reduces the amount of exposing light which would otherwise be reflected back toward the light sensitive layer from the front surface.
Claim 14
Dependent Claim
32 words
A method according to claim 11 wherein, during the exposure step, the majority of the area of the light sensitive layer is simultaneously exposed with light from behind the light sensitive layer.
Claim 15
Dependent Claim
29 words
A method according to claim 11 wherein the integral lens sheet is of non-laminated construction and there is no intervening support between the lens element and the antihalation layer.
Claim 16
Dependent Claim
30 words
A method according to claim 11 wherein, during the exposure step, the light sensitive layer is simultaneously exposed to all of an integral image from behind the light sensitive layer.
Claim 17
Dependent Claim
37 words
An integral image element according to claim 1 wherein more than 80% of visible light reaching the reflective layer from in front of the layer, is reflected before penetrating the reflective layer a distance of 5 microns.
Claim 18
Dependent Claim
37 words
An integral image element according to claim 3 wherein more than 80% of visible light reaching the reflective layer from in front of the layer, is reflected before penetrating the reflective layer a distance of 5 microns.
Claim 19
Dependent Claim
35 words
A method according to claim 6 wherein more than 80% of visible light reaching the reflective layer from in front of the layer, is reflected before penetrating the reflective layer a distance of 5 microns.
Claim 20
Dependent Claim
35 words
A method according to claim 8 wherein more than 80% of visible light reaching the reflective layer from in front of the layer, is reflected before penetrating the reflective layer a distance of 5 microns.
Claim 21
Dependent Claim
35 words
A method according to claim 11 wherein more than 80% of visible light reaching the reflective layer from in front of the layer, is reflected before penetrating the reflective layer a distance of 5 microns.
