Definitions

  • the present invention relates to a method and apparatus for use in producing three-dimensional imagery.
  • three-dimensicnal imagery has essentiall been produced with means that present different aspects of objects to each eye and usually with filtered, polarised or oscillating imagery that can be observed through filtered, polarised and/or oscillating viewers or spectacles.
  • Lenticular arrays, static or dynamic double vision strips an viewing slots arrangements also attempt a similar effect without the use of such viewers or spectacles.
  • three-dimensional imagery is an expression that h been in common use for many years. Since its first use, the meaning of the term has been extended to encompass a wide variety of depth enhancement imagery, as well as imagery tha actually contains three visual dimensions. Within the range of relevant methodologies, equipment and effects, there can be said to be two broad and general categories.
  • One of these categories involves imagery containing a single angle of view of an object.
  • the other applies to images that simultaneously comprise two or more angles of view of essentially the same object.
  • SUBST ⁇ TUTE SHEET Rule26 dimensional. Usually, these arrangements present two spaced angles of view, acquired at distances of 2 1/4 - 2 1/2 inches apart with a common centre, by the use of methods and means that isolate left views to left eyes and right views to right eyes.
  • Left and right view separated systems include spectacles, viewers and visors ranging in sophistication from (as indicated hereinbefore) simple filtered or polarised spectacles to liquid crystal visors synchronised to screen signals.
  • Other techniques for keeping left and right angles of view visible only to the corresponding eye include view differentiating lenses - particularly lenticular arrays and separated static right and left image strip arrangements.
  • holograms produce three-dimensional imagery containing multiple angles of view. Further, there are many combinations of these various systems.
  • a method of producing three-dimensional imagery including displaying on a screen, imagery including two or more spaced- apart angles of view about a common centre and being segmented and separated; said separated segments of imagery being viewed through grid means of a size and shape corresponding substantially to the dimensions of said segments of imagery, wherein said grid is placed at a distance from said screen, such that segments of imagery acquired left of a common image centre are seen through said grid substantially by the left eye of a viewer, while segments of imagery acquired right of the common image centre are seen through the grid substantially by the right eye of a viewer; the arrangement being such that the relationship of left and right segments of imagery relative to said grid is maintained by oscillation of said grid relative to said segments of imagery appearing on said screen, in substantial synchronisation, and at a speed which produces coherent, complete, three-dimensional imagery to the eyes of a viewer.
  • a method of producing three-dimensional imagery including displaying on a screen surface, imagery containing two or more spaced-apart angles of view about a common centre, and which angles of view have been segmented and separated; said segmented and separated angles of view being viewed through sections of a grid, of a size and shape corresponding substantially to the dimensions of said segments of imagery; said grid being placed at a distance from said screen where segments of imagery acquired left of a common image centre are seen through sections of said grid substantially by the left eye of a viewer, while segments of imagery acquired right of the common image centre are seen through grid sections substantially by the right eye of a viewer; the relationship of left and right segments of imagery, relative to said grid sections being maintained when said imagery is displayed on said screen, by oscillation of said grid sections in synchronisation with the display of said segments of imagery at a speed which produces the appearance of a coherent, complete, three-dimensional imagery.
  • a method of producing three-dimensional imagery including displaying on a screen surface, imagery containing two or more spaced-apart angles of view about a common centre, and which angles of view have been segmented and separated; said separated and segmented angles of view being viewed through sections of a grid, of a size and shape corresponding substantially to the dimensions of said segments of imagery; said grid being placed at a distance from said screen where segments of imagery acquired left of a common image centre are seen through sections of said grid substantially by the left eye of a viewer, while segments of imagery acquired right of the common image centre are seen through grid sections substantially by the right eye of a viewer; the relationship of left and right segments of imagery, relative to said grid sections being maintained when said imagery is displayed on said screen, by oscillation of said grid sections in synchronisation with the display of said segments of imagery at a speed which produces the appearance of a coherent, complete, three-dimensional imagery; and wherein said grid sections become substantially invisible to the eye as a transparent window between said eyes of a viewer
  • an arrangement for producing three-dimensional imagery including means for displaying on a screen surface imagery containing two or more spaced apart adjacent angles of view about a common centre and which angles of view have been segmented and separated; a grid means being provided in front of said screen such that said separated and segmented angles of view of said imagery are viewed through sections of said grid, of a size and shape corresponding substantially to dimensions of said segments of imagery; said grid means being spaced apart from said screen by a distance, such that segments of imagery acquired left of a common image centre are seen through sections of said grid substantially by the left eye of a viewer, while segments of imagery acquired right of the common image centre are seen through grid sections substantially by the right eye of a viewer; the relationship of left and right segments of imagery, relative to said grid sections being maintained when said imagery is displayed of said screen by oscillation of said grid means and grid sections, in synchronisation with the display of said segments of imagery on said screen at a speed which produces the appearance of coherent, complete, three- dimensional imagery.
  • Fig. 1 is a diagrammatic plan view of one form of the present invention
  • Fig. 2 is a diagrammatic plan view of a further form of the present invention.
  • this invention provides a method and an apparatus for producing imagery that can be displayed on a screen and viewed through an oscillating grid so that the imagery appears entirely in three physical dimensions.
  • the invention combines two discoveries. Each of the discoveries are extensions of previous discoveries related to earlier inventions and both of the new discoveries permit improvements on these earlier inventions.
  • the first improvement involves the presentation of three- dimensional imagery on a screen.
  • the Pulseometor comprised two discs of transparency graduated from complete to zero, rotating in opposite directions so that each angle of view projected through the discs fades and brightens in illumination in opposition to the other view.
  • Daponte' s discovery and invention demonstrated only partial alignment of two images in three dimensions, and the proportion of the images so aligned was small, comprising less than one quarter of the horizontal length of the image.
  • this angle of separation and the distance between the background and the foreground of the object is dependent upon the distance of the object centre; the total depth of field; type of lenses used; centres of focus; and vertical as well as horizontal alignment of the images.
  • the angle is always very small for objects closer than 40 feet and the differences between both images difficult to discern; despite the physical separation of the image centres, high quality resolution equipment is essential.
  • this angle of view is less than one quarter of a degree for objects at less than forty feet.
  • three-dimensional imagery can be produced by segmenting left and right angles of view of an object and arranging the strips on a flat surface separated by slats, or similar dividers, so that observers can position their eyes to have the left eyes seeing left image strips while the slats block the left eye views of the right image strips and the right eyes see the right image strips, while the slats block the right eye views of the left image strips.
  • the cyclostereoscope comprises a circular grid rotating about a screen on to which left and right adjacent angles of view were projected through the grid.
  • Savoye envisaged the grid, alternatively blocking each eye view of a different combination of strips of angles of view and the whole grid rotating to sequentially reveal all segments at a speed that would permit memory and vision to together perceive the strips combined as two whole images in three dimensions.
  • This Savoye achieved partially and prescribed zoned seating arrangements to confine viewers to areas where three- dimensional views were optimised and views of two overlapping images minimised.
  • An improved grid viewing system is an exclusive feature of this invention which overcomes the zonal problems of the Savoye idea as well a dispensing with the limitations of a rotating, circular grid.
  • images containing two, or more, adjacent angles of view acquired around the common centre of essentially the same object can be aligned in three complete, and coherent, dimensions, except the extreme outer edges, in increasing divergence of angle, with increasing separation between the different images, and the corresponding viewing eyes.
  • the system applied to two or adjacent angles of views acquired around a common centre of an object, where the centre of each different view are horizontally separated from approximately a quarter of an inch to five inches for any two adjacent angles of view.
  • the grid system can be supplied by grids formed with a liquid crystal display synchronised with the segmentation of the imagery.
  • the segmented and separated imagery can be oscillated together in synchronisation so that their functions are maintained at a speed, for example in excess of fifty hertz, where the segments merge into a complete, coherent, three dimensional image and the grid lines are oscillating too fast to be seen.
  • This combination produces zone-free three-dimensional imagery of any angle capable of human perception by widening or narrowing the grid lines, without inertial limitations, or incompatibility with almost all conventional equipment.
  • three dimensional imagery has been created and viewed as what could be termed, "the two separate views” type. This can be done through spectacles, known means and apparatus and the like. Essentially however three- dimensional imagery of the "two separate views” type involving separate right- and left-hand views and the sequential blocking off of these views, is not capable of producing visual realism as people are used to experiencing it. In other words, as the eyes normally communicate the views to the brain. Such three-dimensional imagery tends to be identifiable as imagery and thus unnatural.
  • the eye should in many cases be conceived as something of a dynamic sensor.
  • the eyes of a human being generally see both horizontal and vertical planes substantially simultaneously, together with constantly varying fields of depths and focal points.
  • This essential dynamic sensing, coupled with the memory, maintains impressions of infinitely variable views of everything seen by the eyes.
  • the mind is not given one clear left or one clear right view, but is continually given a range of different partial and adjacent images. These varying partial and adjacent images are combined by the mind or brain of a human being into a single coherent whole which has depth of image and which clearly appears in three dimensions.
  • the eyes of a human are rapidly and continuously scanning. As indicated, they do not, it is believed, continuously focus on one point, giving one right view and one left view.
  • the eyes have a continuously changing field of view and both eyes are continuously shifting over varying points, one crossing over the other's field of view.
  • humans are often continuously moving their heads, and eye balls are often moving within their sockets.
  • a fundamental feature of the present invention is that it produces a commercially viable method for producing three- dimensional imagery, by removing the necessity for wearing view differentiating spectacles and for using other intermediate opticals between the imagery and the observer.
  • the present invention in its preferred forms, accomplishes the production of wide angle three-dimensional imagery, with comparatively little alteration and addition to existing technology, by containing about a common centre within each image, multiple, adjacent angles of view that are displayed partially and progressively across the screen, in apparent full alignment, as separated image segments, or as a combination of separated image segments, changing to cumulatively reveal the continuously varying spatial displacements between the segments of images on the screen and, at sufficient speed, as constant visual displacements between the subject elements of a steady, single, coherent and complete three-dimensional image.
  • the present invention also provides that the angles between the multiple views about a common centre of each image are such that the rapidly changing segments of images containing the angles produce an apparent constant visual displacement between the subject elements of the image, at the same time that the subject elements within the image appear to remain in alignment, so as to prevent or minimise the appearance of more than one image, or multiple imagery within any part of the image.
  • production means acquisition, generation or construction for immediate display upon a screen, or immediate transmission for display, or immediate broadcasting for display.
  • production can mean acquisition, generation, or construction for storage and later display, transmission, broadcasting or projection.
  • Equipment used for acquisition includes cameras, cine cameras, video cameras, holographic camera arrangements, or any device capable of acquiring imaging containing multiple, adjacent angles of view about a common centre in a manner such that the acquired imagery can be presented, separated and segmented for display so as to appear three-dimensional on a screen.
  • Segmentation of the multiple adjacent angles of view about a common centre can take place as the imagery is acquired, within a camera-like system, or anywhere before display such as during, or as part of, film processing; storage input or retrieval; or editing; for the production of slides; film prints or video tapes for release; in transmission or broadcasting; or on reception.
  • appropriate segmented imagery can be manufactured in the generation of imagery, such as computer imagery or symbology, or in the production of caricatures.
  • image a single whole image is meant such as contained by a slide; one frame of a film; one image on a video tape; an x-ray; or any other clearly definable view capable of being recorded, stored, transmitted, broadcast, displayed, projected, presented or generated to duplicate actual objects, symbols; or represent objects or symbols such as computer generated imagery or caricatures.
  • image or imagery series of single images presenting the same view or continuation of a view are included.
  • display projected, presented, illuminated or generated so as to be visible to the eye.
  • screen any surface upon which the imagery can be displayed, presented, projected or generated so that it becomes visible; or any volume in which imagery can be made to appear.
  • alignment is meant that each imagery is registered apparently exactly upon any other in size, shape, vertical and horizontal position, so that multiple images appear as differing only in the appearance of depth or dimensionality and never as more than one image, or more than one part of any image, necessarily the same shape, that is revealed progressively across the screen.
  • the size of the segments will vary according to the medium used for acquisition or viewing.
  • the present invention provides a method and arrangement, whereby imagery is recorded in such a manner that realistic and commercially viable three-dimensional imagery can be subsequently, or substantially simultaneously, be shown on a screen surface.
  • the imagery can be recorded on any appropriate media, such as film, tape, slides, holograms and the like.
  • the imagery is recorded on media so that it can be subsequently shown such as in the cinema by way of slides or photographs, on a television, on a video set and the like.
  • means for recording the imagery such as a camera or cameras
  • means for recording the imagery are in the form of a camera or cameras which are themselves, or in conjunction with appropriate transmission means, able to immediately transmit the recorded imagery to means such as television sets and the like which will receive and show the recorded imagery on a screen surface.
  • means for recording the imagery such as a camera or cameras
  • the present invention relates to a method and arrangement for the recording of imagery for subsequent or substantially simultaneous viewing on a screen surface.
  • the present invention does not relate to a method and arrangement for enabling previously recorded imagerv to be viewed on a screen so as to appear in three dimensions.
  • the method and arrangement of the present invention require the provision of a lens or lens system, that allows for the recording or acquisition of two or more substantially adjacent, similarly sized angles of view of imagery or objects that are to be recorded. Generally, it is better to acquire or record a plurality of smaller adjacent angle views rather than a smaller number of larger angle views. It should however be appreciated that in the present invention it is essential that two or more differing angles of view be recorded.
  • the imagery be recorded for subsequent or simultaneous viewing so that at all times only partial and adjacent sections of each angle of view are acquired or recorded.

  • the present invention provides that means be provided in association with the lens or camera, or in association with the recording of the multiple angle views, so that the imagery is recorded in a partial, adjacent and spaced apart manner.
  • the invention requires the provision of a grid, grid system, separator, angle of view interrupter, light or signal blocking mechanism, switch or process means, as a component or feature, essential to the recording of the imagery, so that the imagery as recorded, is recorded partially and from two or more spaced apart, adjacent angles of view.

Abstract

L'invention concerne un procédé et un appareil pour produire des images en trois dimensions en projetant sur un écran une image obtenue à partir de deux angles de vue ou davantage espacés par rapport à un centre commun, cette image étant segmentée et séparée. L'image segmentée et séparée est vue à travers un moyen de grille d'une taille et d'une forme correspondant sensiblement aux dimensions des segments d'image. La grille est placée à une certaine distance de l'écran pour que les segments d'image obtenus à gauche d'un centre commun d'image soient vus à travers la grille essentiellement par l'oeil gauche du spectateur, alors que les segments d'image obtenus à droite d'un centre commun d'image sont vus à travers la grille essentiellement par l'oeil droit du spectateur. La relation entre les segments de gauche et ceux de droite par rapport à ladite grille est maintenue par l'oscillation de ladite grille par rapport aux dits segments d'image apparaissant sur ledit écran.
