Abstract

A method and apparatus for producing three-dimensional imagery, inclusive of displaying on the screen, imagery including two or more spaced-apart angles of view about a common centre and being segmented and separated. The segmented and separated imagery is viewed through grid means of a size and shape corresponding substantially to dimensions of the segments of imagery. The grid is placed at a distance from the screen such that segments of imagery acquired left of a common image centre are seen through the grid substantially by the left eye of a viewer, while segments of imagery acquired right of a common image centre are seen through the grid substantially by the right eye of a viewer. 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.

Description

A method for producing a three-dimensional imaging device 1 for performing the method

Technical field

The present invention relates to a method for producing three-dimensional imaging and to an apparatus for performing the method.

BACKGROUND OF THE INVENTION

Until now, three-dimensional imaging has been created essentially by means which present different angles of object position to each eye and usually by filtered, polarized or oscillating imaging, which can be observed by filters equipped with, polarized and / or oscillating viewers or glasses. Lens systems, static or dynamic double vision bands, and viewing aperture arrangements also attempt the same effect as using these viewers or spectacles.

The term three-dimensional rendering is an expression that has been commonly used for many years. Since its first use, the meaning of the term has expanded to encompass a wide range of depth imaging enhancements, as well as imaging that actually includes three visual dimensions. Within a range of relevant modes, devices and effects, we can speak of two broad and general categories.

One of these categories involves imaging containing a single point of view of an object. The second is used for displays that simultaneously contain two or more angles of view of the same object.

Methods and apparatus that allow two or more different angles of view of the same object to be presented simultaneously are also referred to as three-dimensional. Typically, these arrangements represent two distant viewing angles, obtained at distances of about 5.14 cm to about

6.35 cm (2 1 / 4-2 1/2 inch) apart with a common center, using methods and means that isolate left-side views to the left eye and right-side views to the right eye. Systems separating the left and right views include glasses, viewers, and screens of different levels of performance (as described above), from simple filter or polarized glasses to liquid crystal screens, synchronized with screen signals. Other techniques to keep the left and right viewing angles visible only to the corresponding eye include a distinctive lens view - especially lens assemblies and separate static right and left image lane devices.

In addition, holograms create three-dimensional imaging containing multiple viewing angles. Furthermore, there are many combinations of these different systems.

However, despite a number of methods and techniques for increasing the depth of the image and creating images containing three visual dimensions, all have very limited use and have limited commercial and practical success. In particular, none of the known systems is suitable for adapting to most general-purpose imaging systems such as cinemas, video and computer display units, television screens, and the full range of monitors used in everyday life, from medical examinations to entertainment or military surveillance.

It is an object of at least one aspect of the present invention to provide a method and means for presenting three-dimensional imaging, which in some way aims to overcome or minimize the problems and drawbacks associated with methods and means known to date.

Other objects of the invention will become apparent from the following description.

Overview of the drawings

DETAILED DESCRIPTION OF THE INVENTION

As described above, the present invention provides a method and apparatus for performing imaging that can be displayed on a screen and viewed through an oscillating lattice such that the imaging appears integrally in three physical dimensions.

The invention combines two discoveries, each of which is an extension of the foregoing relating to the foregoing inventions, and both new discoveries allow for further refinement.

These two enhancements, combined together, create three-dimensional imaging that is practical and commercially feasible for many purposes for which it is desired.

The first enhancement includes the introduction of three-dimensional imaging to the screen.

So far, it has not been thought possible to display two or more viewing angles obtained around a common center of the same object, in which all elements of each image are fully aligned so that the multiple viewing angles together appear to be a continuous, three-dimensional image, except for the extreme outer edges of the images.

There seem to be two reasons for this. First, due to the general assumption that for humans, three-dimensional representation is primarily a function of the range of human eyes. Second, because the description of human vision by geometry in space necessarily demonstrates that each eye must see any identical point on the screen at a different position to the other eye.

In the first case, there is no defined standard in which different distances between the pupils of the human eyes would be determined as optimal, average, or otherwise defined as generally appropriate for everyone to see a three-dimensional image.

However, it seems widely accepted that for the purpose of forming three-dimensional imaging, separation from about 5.14 cm to about 6.35 cm (2 1/4 / 2 to 2 1/2 inches) between the centers of the image in question is required.

The images obtained by this order of separation around the common center cannot be displayed on the screen so that the eyes without aids appear in one plane completely in three dimensions.

Furthermore, since the depiction of geometry in human observation space shows that each eye must see the same point at a different position on the screen, it was further considered that, with the exception of the center, no points of two or more adjacent images obtained from different angles around the common center, cannot be seen without aids in the same spot on the screen and therefore in one plane and three dimensions.

For both these reasons, it has generally been accepted for many years that two or more images of substantially the same object obtained adjacent, in a manner simulating human eye views, cannot be aligned on the screen and subsequently seen in three dimensions, only if these images are seen separately by the respective eyes, so that neither eye can compare any part of certain two views on the screen and thus observe two different images.

In this century, human perception of three-dimensional imagery was seen as a separate and separate vision from two different angles of sight, seen from a distance apart at the equivalent of the pupil width of the eyes, or about 6.35 cm (about 2 1/2 inch) ).

Ή

Thus, the performance of three-dimensional imaging followed this understanding of its presentations mainly through the view of the distinguishing glasses.

This presentation of three-dimensional imaging with the requirement to wear the appropriate viewing devices seems to be a major obstacle to further expanding the use of such imaging, due to the public's resistance to using this kind of optics.

Other attempts, such as the use of lens systems for displays, have various drawbacks such as limited vision due to the requirement to keep the eyes at the focal center of the lenses. Even more different solutions, such as holographic approaches, are limited by cost considerations.

The primary point of the present invention is that the underlying belief that two or more adjacent viewing angles cannot be flush in three dimensions on the screen to the naked eye is fundamentally flawed and this discovery opens the way for improvements in technology that overcomes the obstacle to Wear viewers to see a three-dimensional image or use techniques with the same or more unwanted characteristics.

In 1923, Demetre Daponte demonstrated that two adjacent viewing angles obtained using centers approximately 6.35 cm (2 1/2 inches) apart can be partially aligned to one axis in three dimensions on the screen by alternately blending each view inside and out against the other.

Dapont's invention demonstrating this discovery was called the Pulseometer. It contained two disks with transparency graded from full to zero, rotating in reverse directions so that each angle of view projected through the disks blended and brightened in the light position exactly opposite the other.

Dapont's discovery and invention showed only partial alignment to the common axis of two images in three dimensions, and the proportions thus to the plane of the images were small, comprising less than a quarter of the horizontal length of the image.

One discovery of the present invention is that images containing two or more adjacent viewing angles can be completely aligned to the same axis in three dimensions per screen, provided that the angle between the views and the distances between the foreground of the object and its background are sufficiently small.

In practice, this separation angle and the distance between the foreground and the background of the object depend on the distance of the center of the object, the total depth of field, the type of lens used, the focal points and the vertical as well as horizontal alignment of the image.

Regardless of all these variables, the angle is always very small for objects closer than about 12.2 m (40 feet) and the differences between the two images are difficult to recognize; despite the physical separation of the centers of a given image, high-resolution equipment is decisive.

As a guide, this viewing angle was found to be less than one quarter of a degree for objects less than about 12.2 meters (forty feet) away.

The importance of this discovery is that in conjunction with another discovery and further refinement of yet another invention, this small displacement angle can be increased in a flexible manner, allowing application to most conventional imaging equipment.

Essentially, this is accomplished by using a variable separation system into two different images and varying the degree of separation as needed.

Like other aspects of three-dimensional imaging, it has been known for over a century that three-dimensional imaging can be accomplished by segmenting the left and right angles of the object and arranging the strips on a flat surface divided by bars or other divisions so that viewers can position their eyes the eyes see the bars of the left image, while the bars block the left eye to see the bar of the right image and the right eye see the bar of the right image, while the bars prevent the bar from seeing the left image.

This well known device creates a three-dimensional combination, but is always limited by the reduction in the overall effect caused by the vision of the manifolds.

One more approach was demonstrated by Francois Savoy in the early 1950s when he produced it and applied for patenting his cyclometer.

The cyclometer contains a circular grid that rotates at a screen on which the left and right angles of view are projected through the grid. The concept described by Savoy foresaw the transfer of the familiar approach of screening visors worn by the viewer to an equally functioning screen device.

Savoye anticipated a grid alternately blocking the eye of each eye to a different combination of streaks of angles, and the entire grid rotating to sequentially reveal all segments of speed, allowing memory and vision together to perceive these combined streaks as complete images in three dimensions.

Savoy accomplished this in part by prescribing seating zones to restrict viewers to spaces where three-dimensional views were optimal and the vision of two overlapping images was minimized.

The enhanced grid inspection system is an exclusive feature of the present invention which overcomes the zone problems of the Savoy idea, as well as bypassing the rotating, circular grid.

It is a second discovery of the present invention that images comprising two or more adjacent angles of view obtained around a common center of a massively same object can be aligned in three complete and continuous dimensions, except for the outermost outer edges, at increased angle divergence by increased separation between different images and corresponding looking eyes.

In practice, it is necessary to segment and separate the images sequentially so that an equal number of equally sized and equally spaced images is present on the screen and then viewed through a vertical grid so that the left eye views the portions of the image to the left they are separated from the common center of the object from the right eye views of the portion of the image to the right of the common center at increased degrees of exclusion as the divergence angles between the images increase.

As a guide, the system was applied to two or adjacent viewing angles obtained around a common center of the object, where the centers of each different view are horizontally separated from about 0.6 cm to about 12.7 cm (from a quarter of an inch to five inches) for any two adjacent points of view.

For extreme close-up or off-visual views, these positions will be smaller or larger.

In order to maintain this relationship in a manner that overcomes the constraints of the rotating, circular lattice, or inertia forces of the oscillating mechanical lattice, the lattice system may be supplied by lattices formed from a liquid crystal display synchronized with the respective segmentation of the display.

To perform full three-dimensional imaging and remove grid lines degrading segmented and separated images, highlighted by grids, they can be oscillated together in synchronization so that their functions are maintained at a speed of, for example, over fifty hertz where the segments merge into a complete, continuous, the three-dimensional image and the grid lines oscillate too fast to be seen.

This connection creates a zone-free, three-dimensional representation of any angle capable of human perception through imaging, in the separation of the widening or narrowing of grid lines, without inertial constraints or incompatibility with almost all traditional equipment.

Until now, three-dimensional imaging has been performed and viewed as something that could be called a kind of two separate views. This can be done by glasses, known means and apparatus and the like. Essentially, however, three-dimensional imaging of the type of two separate views, comprising separate right and left views and sequential blocking of those views, is not capable of creating the visual reality that people are accustomed to by experience. In other words, because eyes normally transmit views to the brain. Such three-dimensional imaging tends to be associated with image creation and is therefore unnatural. There are other shortcomings with these known forms of three-dimensional imaging, including, for example, reducing the angles from which the image can be seen, incompatibility with traditional equipment, transmission and broadcasting difficulties, substandard quality, eye strain and lack of commercial viability and reality, as well as problems many people with abnormal vision.

As a background to the present invention and for purposes of description and definition in this material, it is generally believed that it can be said that the eye should be understood as a dynamic sensor. The eyes of the human being generally see both the vertical and horizontal planes massively simultaneously, along with ever-changing depth fields and focal points. This essentially dynamic perception associated with memory maintains the impressions of the infinitely changeable views of anything seen through the eyes. It is generally believed that the brain does not receive one clear view from the left or one clear view from the right, but continuously receives a range of different partial and adjacent images. These changing partial and contiguous images are connected by one's mind or brain into one coherent whole that has a depth of image and clearly appears in three dimensions.

It is also generally believed that human eyes quickly and continuously scan. As mentioned above, they, as believed, still do not focus on one point, giving one view from the left and one view from the right, of the perception of creating two three dimensions. The eyes have a continually changing field of view, and both eyes continuously move across the changing points, crossing the field of view of one eye with the other. Furthermore, people often still move their heads, as does the eyeball inside their holster. Thus, far from what the mind or brain of a human being receives, two unequal changing views or photographs (one right and one left), what the mind or brain receives are continuous partial and adjacent, segmented, and separate views of the image.

It has hitherto been believed that optical devices using differentiated views for simulation are limited by inherent constraints. These limitations refer to these systems and means for presenting three dimensions in individual individual horizontal planes with a fixed field depth and a fixed focal length. From the above it will be understood that these are not realistic and are perceived as such. In practice, these known systems are precluded from reproducing realistic three-dimensional imaging.

A fundamental feature of the present invention is that it provides a commercially viable method for performing three-dimensional imaging by eliminating the need to wear a goggle distinguishing glasses and using other intermediate optical devices between the image and the viewer.

The present invention, in its preferred embodiments, achieves the formation of wide-angle, three-dimensional imaging by comparatively small adjustments and addition to existing techniques, by embracing around a common center within each image, multiple adjacent angles of view that appear partially and sequentially across the screen at aligning, as separate image segments, or as a combination of separate image segments, changing to cumulatively reveal continuously varying spatial displacements between image segments on the screen and, at a sufficient rate, as constant visual displacements between elements of a stable, individual object, continuous and complete three-dimensional image.

The present invention also ensures that the angles between multiple views around a common center of each image are such that rapidly changing segments of the images accommodating the angles create an apparent constant visual displacement between the elements of the image object, while making these elements appear within the image as remaining in the same axis to prevent or minimize the appearance of more than one image, or multiple display within any part of the image.

The term production means acquiring, generating or assembling for immediate display (display) on the screen, or instant transmission for the display, or immediate broadcast for the display. In addition, production may mean acquiring, generating or assembling for preservation and later display, transmission, broadcast or projection.

The acquisition device includes cameras, film cameras, camcorders, holographic camera devices, or any image acquisition device incorporating multiple, adjacent angles of view around the same center in such a way that the acquired image can be presented, separated and segmented for display by the screen will appear as three-dimensional.

Segmentation of multiple adjacent angles of view around the same center can occur when the image is drowned, within a camera of a similar system, or anywhere in front of the display as during or as part of a film processing; preservation of entry or retrofit; or editing; for slide statement; cinematographic copies or videotapes for presentation; transmission or broadcast or reception.

In addition, a suitable segmented image may be produced in a respective generation of the given image, such as computerized image, symbology, or in the manufacture of cartoons.

Image means a single whole image, such as contained in a slide, one film frame, one video tape image, X-ray image or any other, clearly identifiable view capable of recording, preserving, transmitting, transmitting, displaying, projecting, present or generated to duplicate actual images. objects, symbols, or represent objects or symbols such as computer-generated images or cartoons. In addition, a series or individual images representing the same view or continuation of a view are included in the image or display.

A display is understood, projected, illuminated or generated to be visible to the eye.

Screen means any surface on which a given image can be rendered, expressed, projected or generated to become visible; or any volume that can be made to appear.

Axis alignment means that each image appears to be in opacity exactly on any other in size, shape, vertical and horizontal position so that multiple images appear to differ only in the appearance of depth or dimensionality, and never more than one image, or more than one part of any image, necessarily of the same shape that is gradually shown on the screen.

In practice, the size of the segments will vary according to the means used to obtain or view.

The present invention provides a method and apparatus for recording such that a realistic and commercially viable three-dimensional image can be displayed on the screen surface subsequently or simultaneously. This image can be recorded on any suitable media such as film, tape, slides, holograms and the like. In one embodiment of the present invention, the image is recorded on the media so that it can subsequently be shown as in a cinema using slides or photographs on a television, for displaying essentially

The present invention enables a video kit and the like. In other embodiments of the invention, the image recording means, such as a camera, is in the form of a camera or cameras, either alone or in conjunction with suitable means of transmission, capable of instantly transmitting the recorded image to a television device and the like that will receive and display recorded image on the screen surface. For example, as television cameras used in broadcast workplaces for television news, sporting events and the like. These are just examples. It should therefore be understood that the present invention relates to a method and apparatus for recording images for subsequent or simultaneous viewing on a surface of a screen.

does not relate to a method and apparatus for viewing a previously recorded display on the screen as appearing in three dimensions.

The method and apparatus of the present invention require the provision of a lens or lens system that permits the recording or acquisition of two or more materially adjacent, equally large viewing angles or objects to be recorded. In general, it is better to obtain or record a plurality of views at smaller angles rather than a smaller number of views at larger angles. However, it should be understood that in the present invention it is essential that two or more different viewing angles are recorded.

In addition, it is another feature of the present invention that the image is recorded for subsequent or simultaneous viewing so that only partial and adjacent portions of each viewing angle are always acquired or recorded. As will be understood, when the display of a given display occurs, none of the multiple angles of the eye appear completely at any moment in the eye, but are only revealed as segment sequences at a certain speed to the human eye that connects these segments together at different angles. that when viewed, the recorded image is perceived by the eyes as having a depth separate to provide a breaker of the mechanism, component and being in three dimensions; i.e. in accordance with the normal function of human eyes.

In one preferred embodiment of the present invention, partial and adjacent viewing angles are recorded in a non-sequential manner, using the apparatus and method of the present invention. Recording of these non-sequential adjacent and partial viewing angles in accordance with the present invention allows these non-sequential adjacent and partial viewing angles to be subsequently depicted by means of the present invention so that the viewer's eyes can see them with depth of view and substantially in three dimensions.

The present invention ensures that the means will be provided in association with a lens or camera, or in a multiple angle view recording association so that the image is recorded in a partial, adjacent, and spaced manner. To this end, the present invention requires grids, grid angle, light of the switching means and / or characteristic system, separator, or signal blocking or process as a feature decisive for recording a given image such that the image as it is recorded is partially and two or more distant, adjacent angles of view.

The present invention is described with reference to an image recorded from two distant angles of view, one left angle and the other right angle. However, this is only an example and it should be understood that images can be recorded from two or more angles of view.

The means for use in recording partial and adjacent multiple viewing angles may be separated from or incorporated into recording devices such as a camera. Hereinafter, various embodiments of the present invention will be described, by way of example only, and with reference to the accompanying drawings, but it should be understood that these are only examples. For example, a camera may have appropriate means therein that cause imaging to be partial and adjacent, such means may take the form of, for example, a breaker such as a grid system that may be embedded in the camera but arranged to avoid shutter interference. or browsing features. Furthermore, any such device should be time-adjusted to prevent as much as possible line-formation, interruption, moiré or other optical noise, image distortion or degradation.

However, it is envisaged that in one form, the camera may be an electronic camera, which may be programmed to record partial and adjacent angles of view of the object or objects being recorded. Such a camera may have a plurality of spaced lenses, or alternatively a plurality of these cameras may be used, after which the recorded image is mixed and processed.

In embodiments of the present invention, where an interruption or grid device may be provided within the camera, the device may be provided in front of, within, or behind the lenses or at any position characterized by positively interrupting the acquisition or recording of images through the lenses such that only partial and adjacent images are recorded or recorded by the camera.

It is envisaged that if such a device is incorporated into a camera, the grid or interruption device will preferably be located behind the lenses, adjacent and as close as possible to the film plane and synchronized with the camera shutter or may replace the shutter or be built into the film path .

In various embodiments of the present invention, where a plurality of viewing angles have been acquired and recorded by means of films or electronically, the recorded multiple viewing angles can then be sequentially changed to include partial and adjacent viewing angles, such as by known mechanical, electro-optical, electrical, or other means such as segmentation mixtures and the like.

It is further envisaged that media, such as film or tapes, with a programmed grid or pattern applied thereto, or gaps in simplifying the invention with them, could be used in a camera for a recording assembly. In yet another embodiment, it foresees that display units presenting image disrupting patterns could be used to mix multiple viewing angles. For example, the liquid crystal display could be used such that the presented image segmentation lines, or gaps moving the display at the desired rate, form a dynamic optical grid.

The invention will now be further described with reference to its preferred embodiments and with reference to the accompanying drawings (as discussed above).

In a preferred embodiment of the invention, the display is shown on the screen as a result of a computer generated or generated on the screen or displayed on the screen by means of a fuse. In the accompanying drawings, by way of example only, the representation is shown as seen through the respective means of the grid (hereinafter described herein).

The screen 1 is shown as having a screen surface 2 and grid means is physically secured in front and spaced from said screen surface 2, the grid means 2 j ^e preferably in the form of a display screen of a liquid crystal, which during operation generates a plurality of vibrating (oscillating) portion of the grid 4. through which the display can be seen on the screen. Other forms of grids may be used if desired. E.g. physical grids extended over the front of the screen, provided with a plurality of slots or holes of varying depth. However, it is preferred that the lattice means have a plurality of lattice portions or sections therein and that the lattice means 2 is in the form of a liquid crystal display screen or other suitable electrical or chemical-optical device that provides physical separation of imaging.

The liquid crystal display screen is preferably arranged such that the grid 2 oscillates according to the respective requirements of the present invention. In other embodiments of the invention, the grid means can be moved or oscillated by additional mechanisms or by electrical energy.

By way of example only and with reference to FIG. 1 of the accompanying drawings, the grid 2 is shown separated from the surface of the screen 2 ^and one aspect of the present invention is shown (schematically) embedded in a housing or cover 9 in front of the screen 1 and is a television screen, cinema screen or the like. .

In a further embodiment of the invention, shown by way of example only, with reference to FIG. 2 of the drawings, a plurality of spaced grid means 2 may be provided to form portions of the channels or slits 4 therebetween so that when oscillating or moving these, the display on the surface of the screen 2 will be seen in three dimensions through them.

With respect to other embodiments of the present invention, the screen 1 and the distant grid means 2 may be positioned or embedded in a housing 9 so as to be materially integral. Alternatively, these may be separated from each other.

It will be understood that at least the lattice means 3 may be, for example, in the form of crystalline, liquid crystals or similarly functioning electro-optical materials.

For use in forming a suitable grid or surface, the materials may be, for example, inorganic compounds such as gilenium arsenide, lithium niobate, potassium dihydrogen phosphate and barium borate; as well as organic compounds such as methyl nitroaniline and nitroaminostilbene; also electron donor materials such as amino, methoxi and hydroxy groups; and electron acceptor groups such as nitro, cyanide, ester and nitroso groups; polymers; polyenes; and polydiacetgenes or any other material with electro-optical properties; low frequency properties; a non-centrosymmetric molecular structure; or crystalline structures in which the anions have been completely replaced by electrons as in complex compounds such as alkalid, potassium hexamethyl-sodium hyxacyclene (potassium hexamethyl hyxacyclene sodium). The respective electro-optic material may be arranged in individual pieces, eg blocks, plates or cuttings, or in a plurality of pieces, large or small pieces of any shape, in films, thin films, solutions, suspensions interposed between other materials such as glass, as mixtures with other electro-optical compounds or as mixtures with other materials that are not electro-optical compounds.

For example, where the electro-optic grid materials are arranged in rows, bars, strips, bars, panels or fibers, these may be located in rows, partial rows, alternating rows, parallel rows, horizontal or vertical rows (or both). ) or in intersecting rows. Further, with different lengths and sizes, and at different locations within the display.

As mentioned, these are merely examples, and grids such as grids formed from any suitable material with slits therein, adapted to oscillate accordingly, can be used to meet the requirements of the present invention.

As understood, in practice, the present invention allows a three-dimensional image display and its three-dimensional vision (whether generated, otherwise produced or projected) in a manner as described and claimed in our International Patent Application No. PCT / AU92 / OO199. Accordingly, the respective projection projected onto or formed on the screen, or otherwise illustrated, includes its display on the screen, the projection comprising two or more spaced, adjacent angles of view about a common center that are shown in a segmented and spaced manner, substantially sequentially or alternatively on the screen. Separate segments are seen through portions (sections) of the grid as described with reference to FIG. 1 and 2 of the accompanying drawings having portions or apertures of a size and shape real corresponding to the dimensions of the display segments shown on the screen. The grid means is spaced apart from the screen such that the display segments obtained to the left of the center of the common image are viewed through portions of the grid only by the left eye of the viewer, while the display segments obtained to the right of the center of the common image are viewed through portions of the grid only by the right eye of the viewer.

The correlation between left and right image segments, relative to the grid and portions thereof, is actually maintained when the portions of the grid oscillate to allow the image to be seen through the oscillating grid, the oscillation being in speed and synchronized with that the image appears to the eyes of the viewer (through the means of said lattice) as continuous, complete and in three dimensions. It has been found that this avoids flickering, totally or partially revealing any single viewing angles, and it has also been found that portions of the grid, when oscillated, become substantially invisible as a translucent window between the viewer's eyes and the screen.

It should be understood that modifications and refinements of the present invention may be made without departing from their respective scope as set forth in the appended claims.
