A method is provided for generating an autostereoscopic display. The method includes acquiring a first parallax image and at least one other parallax image. At least a portion of the first parallax image may be aligned with a corresponding portion of the at least one other parallax image. Alternating views of the first parallax image and the at least one other parallax image may be displayed.

Critical alignment of parallax images for autostereoscopic display

A method of using a computer to generate virtual autostereoscopic images from a three-dimensional digital data set is provided. The method includes establishing a first point of view and field of view of a subject volume including a region of interest. The method also includes reading at least one scene parameter associated with the field of view of the subject volume. The method also includes determining a second point of view offset some distance and along some vector from the first point of view based on a value derived from at least one scene parameter. The method also includes generating and storing images and relevant metadata from said first and second points of view. The method also includes displaying the stored images by alternatingly displaying stored images from said first and second points of view. The method further includes performing one or more transformations on the alternatingly displayed images.

System and method for three-dimensional visualization of geographical data

A method of using two parallax scanning lenses to capture left and right points of view for stereoscopic three-dimensional display. The method includes establishing first and second parallax scanning points of view and overlapping fields of view of a subject volume including a region of interest. The method includes reading at least one scene parameter associated with the field of view of the subject volume. The method includes determining stereoscopic and parallax scanning setting based on a value(s) derived from at least one scene parameter. The method also includes computer generating and storing virtual parallax scanning stereoscopic imagery.

Parallax scanning methods for stereoscopic three-dimensional imaging

A method of using a computer to generate virtual autostereoscopic images from a three-dimensional digital data set is disclosed. The method includes establishing a first point of view and field of view of a subject volume including a region of interest. The method includes reading at least one scene parameter associated with the field of view of the subject volume. The method includes determining a second point of view offset some distance and along some vector from the first point of view based on a value derived from at least one scene parameter. The second point of view at least partially overlaps the first field of view. The first and second points of view each create a view plane with a view orthogonal to the subject volume.

Optical element parallax scanning device

An image compositing and compression method based on the creation and processing of parallax differences in motion photography. A parallax scanning MOE lens creates discrete parallax differences in the objects in the recorded scene that are perceived by the viewer as enhanced texture and depth when displayed. Using parallax differences in a captured scene, a computer can detect objects for the purpose of creating image compositing mattes. This method allows matte passes to be filmed on location at the time of principal photography, thereby saving costly additional blue/green stage production shoot days associated with traveling matte techniques. In addition, because the mattes are based on parallax scan differences in the recorded scene and not on a uniform color and luminance process, certain conflicting scene subject colors will not have to be avoided. Also, because the matte scenes are recorded on location, the lighting in each of the various elements matches in the final composited image.

Image segmentation by means of temporal parallax difference induction

A method is provided for real time control and manipulation of a moving imaging system lens's (prime, close-up, zoom, or anamorphic) depth of field. A computer control system is programed to perform a coordinated adjustment of a closed loop lens iris (aperture) and the shutter angle of a motion picture camera. The iris of the lens is reduced in size while simultaneously increasing the motion picture camera shutter angle an equal exposure (light transmission) amount, therefore, increasing the apparent image depth of field without a perceivable luminance shift. The image depth of field can be reduced by performing the above operation in reverse.

Real time camera and lens control system for image depth of field manipulation

A lens aperture of an autostereoscopic camera is moved in a parallax scanning pattern through a plurality of disparity positions offset from the optical axis of the camera lens. Images of a scene being photographed, as viewed through the lens aperture in its various disparity positions, are recorded for subsequent display, which produces a three dimensional illusion when viewed on a conventional display with the unaided eye. The size of the lens aperture and the parallax scanning pattern are adjustable to suit conditions. The lens aperture may be defined by a through-hole in an opaque card, a plurality of interleaved leaf elements, or a planar array of cells switched between transparent and opaque states. In addition to stereoscopic imaging, the moving lens aperture principle of the present invention may be utilized in range-finding and camera image stabilization applications.

Autostereoscopic imaging apparatus and method using a parallax scanning

Autostereoscopic imaging is achieved by acquiring succession of first and second image frames from at least two different points of view, and image processing the first and second image frames, such that progressively different partial images of at least focussed and converged subject images in the second image frames are substituted for corresponding subject partial images in the first image frames in repeating sequence on a corresponding image frame-by-image frame basis to create a succession of composite image frames. Two-dimensional display of the resulting succession of composite image frames is perceivable in three-dimensional illusion.

Autostereoscopic imaging apparatus and method using suit scanning of

A single camera autostereoscopic recording system includes a single image recorder having a single optical path moved along a scanning path defined by a pair of rails and an arm movable on the rails substantially continuously for a plurality of scanning cycles. Alternatively a lens maintains the point of convergence. A path defining structure includes the ability to adjust the convergent point as well as the extent of travel along the scanning path or disparity of the images. The convergent point of the scanning path can be manually or automatically adjusted using a range finder. A unique driver structure including a reciprocating armature and stator provides scanning motion with reduced reactional forces. The degree of motion of the recorded images is used to adjust the amount of travel along the scanning path. Synchronization between the driver and the recorder is bi-directional for double exposures. The recorded image is adjusted in recording or in display as a function of the position in the scanning path.
