The autostereoscopic image selection device has an opaque material applied thereto in gaps between the plurality of lenticules. The opaque material is applied to the autostereoscopic image selection device in a soft aperturing manner, the soft aperturing manner comprising applying the opaque material such that the opaque material is tapered from the gaps over the plurality of lenticules. The opaque material can be applied in accordance with a windowing function. ## Claims ### Claim 1 An apparatus comprising: an autostereoscopic image selection device comprising a plurality of lenticules; and an opaque material applied to the autostereoscopic image selection device in gaps between the plurality of lenticules; wherein the opaque material is applied to the autostereoscopic image selection device in a soft aperturing manner, said soft aperturing manner comprising applying the opaque material such that the opaque material is tapered from the gaps over the plurality of lenticules, wherein tapered from the gaps comprises appearance of the opaque material being gradually reduced from opaque at a center of each gap to transparent at edges of the opaque material. ### Claim 2 (depends on 1) The apparatus of claim 1, wherein the opaque material is applied in accordance with a windowing function. ### Claim 3 (depends on 2) The apparatus of claim 2, wherein the windowing function comprises one from a group comprising cosine windowing and Hamming windowing. ### Claim 4 (depends on 1) The apparatus of claim 1, wherein the autostereoscopic image selection device is a lenticular screen. ### Claim 5 (depends on 1) The apparatus of claim 1, wherein the opaque material is applied to individual elements formed on the autostereoscopic image selection device and subsequently partially removed from the individual elements by cleaning off excess opaque material from the autostereoscopic image selection device. ### Claim 6 (depends on 1) The apparatus of claim 1, wherein the opaque material is formed from a waxy material. ### Claim 7 (depends on 1) The apparatus of claim 1, wherein the opaque material is formed from an International Ink Company (INX) pigment material. ### Claim 8 (depends on 1) The apparatus of claim 1, wherein the opaque material is applied to individual elements formed on the autostereoscopic image selection device and subsequently partially removed from the individual elements. ### Claim 9 (depends on 8) The apparatus of claim 8, wherein partial removal comprises buffing the opaque material to enable the lens surface area to render aperture-corrected autostereoscopic images. ### Claim 10 A method for providing an enhanced image selection device, comprising: applying an opaque overcoat material to an image selection device comprising a plurality of lenticules; and removing selected portions of the opaque overcoat material from the image selection device; wherein the applying and removing operate together with the image selection device to provide a tapered opaque coating that obscures portions of the lenticules according to a soft aperturing technique, wherein the tapered opaque coating comprises appearance of the opaque overcoat material being gradually reduced from opaque at a center of each gap between lenticules to transparent at edges of the opaque overcoat material. ### Claim 11 (depends on 10) The method of claim 10, wherein the soft aperturing technique comprises a windowing technique. ### Claim 12 (depends on 11) The method of claim 11, wherein the windowing technique comprises one from a group comprising cosine windowing and Hamming windowing. ### Claim 13 (depends on 10) The method of claim 10, wherein removing comprises buffing a portion of the opaque overcoat material to configure the lens surface area for rendering soft aperture-corrected autostereoscopic images. ### Claim 14 (depends on 10) The method of claim 10, wherein removing comprises applying pressure while polishing opaque overcoat material on the lenticular screen to reveal a top lenticule surface, thereby forming a reduced section of a cylinder for aperture correction. ### Claim 15 A method for constructing an aperturing device usable with a display, comprising: providing an image selection device comprising a plurality of lenses; applying an overcoat material to the image selection device; and removing a portion of the overcoat material from at least one lens, creating a tapered optical attenuation coated lens array; wherein appearance of the overcoat material on the optical attenuation coated lens array is gradually reduced from opaque at a center of each gap between lenses to transparent at edges of the overcoat material. ### Claim 16 (depends on 15) The method of claim 15, wherein removing the portion of the overcoat material effectively applies a windowing function to the image selection device. ### Claim 17 (depends on 16) The method of claim 16, wherein the windowing function comprises one from a group comprising cosine windowing and Hamming windowing. ### Claim 18 (depends on 15) The method of claim 15, wherein removing comprises buffing a portion of the overcoat material to configure at least one lens surface area for rendering soft aperture-corrected autostereoscopic images. ### Claim 19 (depends on 15) The method of claim 15, wherein the image selection device comprises a lenticular screen. ### Claim 20 (depends on 15) The method of claim 15, wherein the image selection device comprises a fly eye lens. ### Claim 21 (depends on 15) The method of claim 15, wherein removing comprises buffing the overcoat material to configure surface area of at least one lens for rendering soft aperture-corrected autostereoscopic images. ### Claim 22 (depends on 15) The method of claim 15, wherein removing comprises applying pressure while buffing the lenticular screen to reveal top lens surfaces, thereby forming a reduced section of the lenticule for aperture correction.
