Patent number: 4120562Abstract: An autostereoscopic picture is produced by taking a series of two-dimensional views of an object field and projecting them in an enlarger onto lenticular print film. Substantially uninterruputed and non-overlapping lineiform image bands of high image quality are formed on all areas of the lenticular film by scanning the projected images from each two-dimensional view over a predetermined distance along the photosensitive surface. A novel image structure of improved quality is thereby produced.Type: GrantFiled: April 12, 1976Date of Patent: October 17, 1978Assignee: Dimensional Development CorporationInventors: Allen Kwok Wah Lo, Jerry Curtis Nims

Patent number: 4101210Abstract: In the illustrative embodiments of the invention disclosed, autostereoscopic pictures are produced by projecting a series of two-dimensional views of an object field onto a lenticular screen. Substantially uninterrupted and non-overlapping condensed, or lineiform, images of the two-dimensional views are formed beneath each lenticule of the lenticular screen by setting the number M of these images in the image band beneath each lenticule, and hence the total number of two-dimensional views projected, equal to w/m, where w is the lenticule width and m is the width of each condensed image. In order to project the required number M of two-dimensional views while avoiding gaps between adjacent condensed images, the projection lenses and the associated film frames are positioned along a plurality of adjacent, parallel, straight lines in a manner such that the apertures of the lenses are effectively in edge-to-edge contiguous relation.Type: GrantFiled: June 21, 1976Date of Patent: July 18, 1978Assignee: Dimensional Development CorporationInventors: Allen Kwok Wah Lo, Jerry Curtis Nims

Patent number: 4086585Abstract: In the exemplary embodiments of the invention disclosed, a system especially adapted for producing stereoscopic pictures in general photography includes a camera having a plurality of lenses aligned in a row with the optical axes substantially in parallel and the endmost lenses spaced apart by a distance that is productive of a three-dimensional depth of field in the system which matches or exceeds the two-dimensional depth of field of the camera lenses at least under average photographic conditions. Such matching of the two and three-dimensional depths of field, where the limits of the two-dimensional depth of field are based on the lenticule width w of the stereoscopic picture, provide sharply focused, solid stereoscopic images of all objects within the two-dimensional capabilities of the camera lens.Type: GrantFiled: December 27, 1976Date of Patent: April 25, 1978Assignee: Dimensional Development CorporationInventors: Allen Kwok Wah Lo, Jerry Curtis Nims

Patent number: 4063265Abstract: Methods and apparatus for aiding a photographer in determining, coordinating and adjusting numerous variables which bear on the quality of a stereoscopic picture employing a lenticular screen. The variables may include, depending upon the photographic method employed and the scene to be photographed, the desired size of the stereoscopic picture, the resolving power and lenticule width of the lenticular screen, the number and size of two-dimensional picture negatives which are taken and included in the stereoscopic picture, the distance between adjacent camera vantage points from which the negatives are taken, the camera focal length, the distance from the camera to the nearest element or object of the photographed scene, the distance from the camera to the farthest element or object of the scene, and the distance from the camera to an element or object - the "key subject matter" - in the scene which is to lie in the plane of the stereoscopic picture.Type: GrantFiled: March 15, 1976Date of Patent: December 13, 1977Assignee: Dimensional Development CorporationInventors: Allen Kwok Wah Lo, Jerry Curtis Nims

Patent number: 4059354Abstract: An apparatus for composing stereoscopic photographs uses a two-stage optical enlarging system. The two-stage system enables one step composing of a stereoscopic photograph without spacial separation or movement of the two-dimensional views from which the photograph is composed.Type: GrantFiled: October 12, 1976Date of Patent: November 22, 1977Assignee: Dimensional Development CorporationInventors: Allen Kwok Wah Lo, Jerry Curtis Nims

The variables may include, depending upon the photographic method employed and the scene to be photographed, the desired size of the stereoscopic picture, the resolving power and lenticule width of the lenticular screen; the number and size of two-dimensional picture negatives which are taken and included in the stereoscopic picture, the distance between adjacent camera vantage points from which the negatives are taken, the camera focal length, the distance from the camera to the nearest element or object of the photographed scene, the distance from the camera to the farthest element or object of the scene, and the distance from the camera to an element or object -- the "key subject matter" -- in the scene which is to lie in the plane of the stereoscopic picture.Type: GrantFiled: March 15, 1976Date of Patent: July 26, 1977Assignee: Dimensional Development CorporationInventors: Allen Kwok Wah Lo, Jerry Curtis Nims

Patent number: 3953869Abstract: In the illustrative embodiments of the invention disclosed, autostereoscopic pictures are produced by taking a series of two-dimensional views of an object field and projecting them in an enlarger onto lenticular print film. Adjustable-focus and fixed-focus cameras are provided for taking the two-dimensional views, either simultaneously or sequentially, in a manner which automatically accounts for the effect of variation of the camera-to-object distance on the configuration of the enlarger-lenticular print film system, thereby allowing the parameters of the enlarger-print film system to be held constant. The number of enlarging lenses employed may correspond to the number of two-dimensional views to be projected, by virtue of which the stereoscopic picture may be composed in a single projection step, or a single enlarging lens may be used to project the two-dimensional views in sequence.Type: GrantFiled: September 24, 1974Date of Patent: April 27, 1976Assignee: Dimensional Development CorporationInventors: Allen Kwok Wah Lo, Jerry Curtis Nims
