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

Be used to produce the method and apparatus of three dimensional image

The present invention relates to be used to produce the method and apparatus of three dimensional image

Up to now, three dimensional image mainly is to produce by the device of the different aspect that object is provided to every eyes, generally is by optical filtering, polarization and/or vibration viewer or glasses can observedly filter, polarization or vibration imaging.Lens arra, static state or dynamic double vision frequency band are also attempted to reach similar effect with the observation slot device and be need not to use above-mentioned viewer or glasses.

Term " three-dimensional imaging " is for many years general.Since it used for the first time, its implication had extended to and has comprised that the depth of field increases imaging and the actual broad range that contains the 3 D visual elephant.In relevant method, in the scope of equipment and effect, two big fundamental types have been we can say.

A type relates to the imaging of the single angle of visual field that contains object.Another type is applicable to the image of two or more angles of visual field that contain same substantially object simultaneously.

The method and apparatus that can show two or more different angles of visual field of same substantially object simultaneously is also referred to as three-dimensional imaging.Usually these devices utilize the method and apparatus that the left ken of left eye and the right ken of right eye are separated mutually, present two and common center and separate

The angle of visual field spaced apart from each other of inch distance.The system that the left and right ken is separated comprise from (aforesaid) simply filter or polarising glass to the liquid crystal access panel synchronous with screen signal.Other the left and right angle of visual field that makes can only be comprised lens arra of ken separate lenses-particularly and the static left and right visual belting that separates by the technology that corresponding eyes are watched.

In addition, holographic technique produces the three dimensional image that contains a plurality of angles of visual field.The complex art that also has many above-mentioned various systems in addition.

Although the visual depth of field of many increasings is arranged, produce the method and the technology of 3D vision image,, they all have only limited application, and commercial and practical achievement is limited.Specifically, do not have a kind of known system to be applicable to general imaging system, for example film, video recording and calculator display organization are daily from video screen and the various monitor of medical research amusement until military affairs supervision use.

Now contrast the following drawings the present invention is described in detail in detail.

Fig. 1 is the schematic plan view of one embodiment of the invention;

Fig. 2 is the schematic plan view of another embodiment of the present invention.

As mentioned above, the invention provides and a kind ofly on screen, show, watch the method and apparatus of complete three dimensional image by the vibration grid.

The present invention combines two kinds of discoveries, and the extension that every kind of discovery is found before being relates to invention, and above-mentioned two kinds of discoveries are the improvement to former invention in the past.

These two kinds of improvement combine and have produced broad-spectrum three dimensional image with practical and commercial value.

First kind of improvement relates to the demonstration of three dimensional image on screen.

It is believed that, still two or more angles of visual field can not on screen, have been shown so far around a common center acquisition of same object, wherein all key elements of each image are all aimed at fully, except that the utmost point external margin of image, a plurality of adjacent fields of view angle occurs as a single continuous three-dimensional image together.

As if this view have two kinds of reasons.At first, be because following basic assumption: for the mankind, three-dimensional imaging mainly is a kind of function of human eye distance.Its two, be since according to solid geometry to every eyes of the description of human vision proof inevitable with the another eyes at any identical point of seeing on the diverse location on the screen.

In first situation, there is not certain standard to determine distance between the pupil of human eyes, make and see that for everyone three dimensional image is best.Average or generally suitable.

However, people generally believe, in order to produce three dimensional image, need between the heart separately resembling

Inch.

Can not on a screen, present so that its naked eyes people are to aim on three-dimensional fully around a common separately big or small like this image that distance obtained in center.

In addition, because the human solid geometry image of observing shows every eyes and must see same point on the diverse location of screen, so, it is believed that, except the center, two naked eyes of people can not see from the same position of point at screen of two or more adjacent images that the different angle of visual field obtained of a common center, thereby aim at and present three dimensional image.

Owing to two top reasons, as if people think for many years, mode with the simulating human ocular vision, two or more images of the same substantially object that is adjacent to obtain can not be aimed on screen, therefore, have only each to watch image quite dividually, make all any parts of two kens on screen relatively of arbitrary eyes, and watch two different images in this wise, just can regard three dimensional image as.

Since this century, it is promptly about from separating a distance that is equivalent to the interpupillary width of human eye that human consciousness to three dimensional image is understood that always widely

Two positions of inch are when watching, two different angles of visual field of object separately and separately watch.

Therefore, the generation of three dimensional image separates glasses (view differentiat-ing spectacles) by the ken always and watches.

As if the three dimensional image that this needs are put on suitable viewer show to be exactly the major obstacle that this three-dimensional imaging is popularized, and uses this optical glasses because people ignore.

Other technical scheme as lens arra is used for screen, also has defective separately, and as limited ken area, this is owing to need make eyes remain on cause on the lens focus.

The limitation of other technical scheme such as holographic technique is the cost that it is high.

Main points of the present invention are, broken two or more visual fields at all and can not on screen, three-dimensional aim at the basic view of watching with person who happens to be on hand for an errand's naked eyes with the angle, this is found to be technological improvement and has got through road, must put on viewer so that overcome, or adopt other with sample inconvenience or complicated technology more; Watch the obstacle of three dimensional image.

Nineteen twenty-three, Di Maite. Da Bangte (Demetre Daponte) proves, by separately about

Two adjacent angles of visual field that the center of inch obtains can be aimed on partial 3 d ground on screen by the mode that alternately makes each ken dissolve and dissolve another ken.

The invention of relevant this discovery of Da Bangte is called " pulsed instrument (The Pulseome-ter) ".Two gradually become zero transparent plate from fully (complete), and these two dishes rotate with opposite direction.Make each angle of visual field opposite with another angle of visual field on light and shade by penetrating.

The discovery of Da Bangte and invention show that two images are local alignment on three-dimensional, the ratio of the image of Dui Zhuning is little like this, less than 1/4th of visual horizontal length.

One of discovery of this invention is, comprises the image at two or more adjacent fields of view angles, as long as the prospect and the distance between the background of angle between the ken and object are all sufficiently little, just can aim on three-dimensional on the screen.

In fact, angle that separates between the above-mentioned view and the distance between object prospect and the background distance that depends on the object center; Total depth of field; The type of institute's use lens; The focal length center; And the vertical and horizontal aligument of image.

No matter above-mentioned variable how, for the object that is bordering on 40 feet, always above-mentioned angle is very little, the difference between two images is difficult to differentiate; Separate although resemble the reality of the heart, the equipment of high-quality resolution rate is very crucial.Have been found that for 40 feet with interior object, this angle of visual field less than

Degree.

The importance of this discovery is, finds to combine with other improvement of other invention with other, and this very little angular separation can increase by flexible way, thereby can apply on most of image devices.

In fact, this is to realize by a kind of variable system applies of separating is also changed angle separately as required on two different images.

The same with the others of three-dimensional imaging, more than one since century people known by cutting apart the left and right angle of visual field of object, and the plane is divided into many with many laths or other separating device, make beholder's left eye see left visual bar, and lath is blocked the left eye ken of right image, right eye is seen right visual bar, and lath is blocked the right eye ken of left side image.

This system known per can produce three dimensional image, but separately the lath of the ken always reduces general effect, thereby this system is limited to.

Another kind of scheme was proposed by the bright Coase. of Buddhist Sai Woyi (FrancoisSavoye) in early days in the fifties, and he has proposed patent application for " circulation stereo mirror (Cyclostereoscope) " that he creates.

The circulation stereo mirror comprises a circular grid that rotates around screen, and left and right adjacent fields of view angle projects on the screen by grid.

This design by Sai Woyi proposes converts the separately technical scheme of the viewer of the ken that is worn on beholder's eyes to turn round around screen the system with identity function.

The grid that Sai Woyi proposes is alternately blocked the ken of every eye to different angle of visual field slice-group, and the grid of whole rotation represents all parts continuously, and its speed makes man memory and vision feel that together these bands become two complete three-dimensional images.

This technical scheme of Sai Woyi is limited in the beholder on the zone of ken minimum of best and two superimposed images of three-dimensional scence.

The present invention is a kind of improved grid copic viewing system, and it has overcome the region limits problem of Sai Woyi design, has also eliminated the limitation of the circular grid that rotates.

Second discovery of the present invention is, image around two or more adjacent fields of view angles that common center obtained of same substantially object, can be complete on three-dimensional except utmost point external margin, aim at continuously, this is to increase dispersing of angle by the increase along with the separation between different images and the eyes watched accordingly to realize.

In fact, must cut apart and separate image continuously, on screen, present equal number, same size and equally spaced image, watch by vertical grid, increase separating degree (degreesof exclusion) along with the increase of the angle of divergence between image, left eye is separated the ken of the image area on common center right side with right eye the ken of the image area of common objects center left.

In general, be applied in the system at two or more adjacent fields of view angle that an object common center obtains, the central horizontal of each different visual field ground is approximately separately 1 inch to 5 inches concerning any two adjacent fields of view angles.

For extremely near visual field or surpass the unlimited visual field of vision, above-mentioned location can diminish or increase.

For keeping above-mentioned relation with the limitation of the circular grid that overcomes rotation or the mode that overcomes the inertia force of vibration mechanical grille, trellis system can be for cutting apart the grid that synchronous liquid crystal display forms with imaging.

In order to produce the grid line of the complete three dimensional image and the image quality of eliminating the effects of the act, separate by the grid enhancing, resembling of cutting apart and separate can be a kind of for example surpasses 50 hertz speed synchronized oscillation, make each several part be merged into complete, continuous, three-dimensional resembling, grid line can not be seen because vibration is very fast.

By widening or narrow down grid line, above-mentioned complex art produces the three dimensional image of no region limits, has eliminated the inertia limitation or the incompatibility of nearly all conventional equipment.

So far, three dimensional image is by so-called " two kens of separating (the two separateviecos) " type technology creation and watches.This finishes by known devices such as glasses and equipment.But this three dimensional image that relates to " two kens of separating " type of the left and right ken separately and one after the other stifled these kens of breaking can not produce the visual vivid that the people is personally on the scene.In other words, people's eyes normally reach brain with view.Such three dimensional image is counted as easily and resembles, thereby the right and wrong nature.In addition, above-mentioned known three dimensional image also has other defective, for example can see the limitation of the angle of elephant, with the incompatibility of conventional equipment, be difficult to propagate, quality is not good enough, eye fatigue lacks commercial viability and practicality, and many people have undesired vision and the problem that causes etc.

As background of the present invention, and in order to be described in this manual and to limit, people it is generally acknowledged, we can say that eyes can be regarded a kind of dynamic watcher as in many cases.People's eyes generally are to see level and vertical plane simultaneously, and are constantly changing the depth of field and focus.This substantial dynamic senses is being kept the impression of the unlimited variation of the various things that eyes see together with memory.It is generally acknowledged that human brain does not provide a clearly left ken or the right ken, but provide the scope of different and adjacent image continuously.The part of these variations and adjacent image are combined into a single continuous integral body by human brain, and it has and resembles dark and clearly occur with three dimensional form.

People think also that generally people's eyes carry out quick and continuous scanning, are not on focusing on a bit continuously, to provide a right ken and a left ken.Human eye has the continually varying visual field, and two are moved on the point that changes, and fork is worn mutually with the visual field of another eyes in the visual field of eyes.In addition, people are moving-head continuously often, and eyeball also usually moves in eye socket.Therefore, to the human brain transmission be two different variation kens or view (one for right, one be a left side), be in succession part and adjacent and human brain is received, be divided into the view of part and the elephant that separates.

So far, it is believed that, use two different kens of generation intrinsic limitation to be arranged with the optical instrument that carries out three-dimensional simulation principle.These limitation are limited in performance three-dimensional on the single horizontal plane with the fixing depth of field and fixed focal length with these systems and device, thereby are not true to nature, but feel out.In fact, these system known per have hindered and have reproduced three dimensional image true to nature.

An essential characteristic of the present invention is, the invention provides a kind of method with commercial viability, is used to produce three dimensional image, and need not to wear the separately glasses of the ken again, also needn't use resemble and the beholder between the intermediate optical instrument.

The present invention, by its preferred embodiment, can form the three dimensional image of wide-angle, and only prior art is done less change and increase, a common center in each image contains a plurality of adjacent angles of visual field, it is presented on the screen partly and little by little, as the image area of cutting apart, or as the combination of the image area cut apart, aim at fully in appearance, their variation ground spiral shells disclose the continually varying space displacement between the image area long-pendingly, and speed is enough, so that be created in stable, single, the continuous vision displacement between each scenery key element of three dimensional image continuously and completely

In the present invention, angle between a plurality of kens of each visual common center, the feasible vertiginous part that contains the image of above-mentioned angle is created in the apparent continuous vision displacement between the visual scenery key element, simultaneously, scenery key element in image seems still to aim at, so that prevent or alleviate phenomenon as far as possible more than an image, i.e. multiple image phenomenon on any part in the drawings.

The meaning of term " generation " is in order to show immediately on screen, or for emission immediately so that show, or play so that show immediately and obtain, form or construct.In addition " generation " also refer in order to store and demonstration later on, emission, broadcast or projection and obtain, form or construct.

The equipment that is used for above-mentioned " acquisition " can be camera, video camera, TV camera, three-dimensional according to resembling machine or any other can obtain to contain the device of image around containing of a common center a plurality of adjacent fields of view angle, make the image that obtained can be by performance, separately, be divided into part so that on screen, come out with three-dimensional representation.

When in the camera class system, or in other any device, before showing, (for example handle at film; Store input or retrieval; Or in editor's the process, or as an above-mentioned part, so that produce lantern slide; Developing and printing film or broadcast video tape is in emission with in playing or when receiving) when obtaining to resemble, can produce cutting apart around a plurality of adjacent fields of view angle of a common center.

In addition, when formation resembled, computer imaging or when producing caricature for example can be made suitable the resembling of part that be divided into.

" image " is meant single, complete image, as contained image in the lattice of a lantern slide, film, and an image on the video tape; Contained image in the X ray, or any other can clear formation view, they can be recorded.Send, broadcast, demonstration, projection, performance or formation are so that reproduce actual object or symbol or present object or symbol such as computer imaging etc." image " or " elephant " also comprises a series of single image that shows same view in addition, and promptly view is continuous.

" demonstration " is meant projection, presents, throws light on or forms so that can be seen by eyes.

" screen " be meant thereon can show, present, projection or formation resembles, so that any plane that can be seen by eyes perhaps can make any utensil that resembles appearance.

" aligning " is meant that each resembles on size, shape, vertical position and horizontal level and aligns with any resembling of other, thereby it is only different on the depth of field or dimension when a plurality of images are occurred, and seem more than one anything but image, or the more than one part of any image, must be that same shape discloses gradually on screen.

The size of the part of in fact, cutting apart will be according to the media that is used for obtaining or watches and is changed.

The invention provides a kind of method and layout, make to resemble in the following manner to be recorded, that is, true to naturely can on screen surface, show subsequently or substantially side by side with three dimensional image commericially feasible.Resemble and to be recorded on any media such as film, tape, lantern slide, hologram etc.In a kind of form of the present invention, resemble and be recorded on the media, make its afterwards by lantern slide or photo at the cinema in, on television set, device is first-class is shown at picture recording.In other form of the present invention, device such as the camera of record elephant, itself or combine with suitable emitter, can be immediately with the devices such as reaching television set that resembles that is write down, resembling and on screen surface, showing by these device receiving records, for example, the TV camera of uses such as the new face of television relay, sports tournament.Above just for example.Obviously the present invention relates to be used to record then or substantially side by side be presented at the method and apparatus of screen surface.The present invention does not relate to the device that resembles three-dimensional display on screen that can make prior record.

Method and apparatus of the present invention requires equipment lens or lens combination, and it can write down two or more adjacent substantially, that size is similar angles of visual field of resembling of being recorded or object.In general, it is better than writing down less bigger angular field's effect to write down more less adjacent angular visual field.But it should be noted that in the present invention key is to write down two or more different angles of visual field.

In addition, feature of the present invention also is, writes down when resembling for seeing afterwards or simultaneously, and always each angle of visual field has only local and adjacent part is recorded.In other words, when resembling demonstration, neither one is intactly seen by eyes in any a plurality of in a flash angles of visual field, and be that a series of part is revealed, its speed makes eyes in different angles these parts be merged, therefore, when watching, the resembling of the record of being felt by eyes has the depth of field and is three dimensional image; This is consistent with the normal operation of human eyes.

In a preferred embodiment of the present invention, the local and adjacent angle of visual field is that method and apparatus of the present invention is write down in non-mode in succession.According to the record of this non-adjacent and local angle of visual field in succession of the present invention, make that this non-adjacent and local angle of visual field in succession is one after the other in sight according to the present invention, thereby in beholder's eye, see three dimensional image with depth of field.

The invention provides the device that has lens or camera or carry out many angles of visual field record, make to resemble with the part, adjacent and mode that separate is recorded.For this purpose, the present invention requires to be provided with grid, trellis system, separator, angle of visual field contact maker, light or signal block up breaking mechanism, switch or processing unit, these features are vital for the record of elephant, make to resemble partly to be recorded from two or more adjacent angles of visual field of separating.

The present invention be directed to from resembling of two angles of visual field of separating (a left angle of visual field, a right angle of visual field) records and be described, but this only is for example, obviously resembles and can carry out record from two or more angles of visual field.

Employed device can separate with tape deck such as camera when the local and adjacent a plurality of angle of visual field of record, also can be contained in the camera.Contrast accompanying drawing below, only describe the present invention by way of example.The proper device of for example can packing in camera makes to resemble to be become locally with adjacent, and for example, such device can be the form such as the trellis system of the continuous device that continues, and trellis system can be packed in the camera, but will avoid interference shutter or scan function.In addition, any such device should be regularly to eliminate lines, flash of light, ripple or other optical noise as much as possible, and distortion or image become bad.

But also can conceive, in a kind of form of the present invention, camera is an electronic type, can programme, thereby can write down the part and the adjacent angle of visual field of object.Such camera can have a plurality of camera lenses that separate, and perhaps a plurality of such cameras use together, and the image to record mixes, handles then.

In camera of the present invention, be provided with in the form of continuous continue device or grid device, grid device can be located at before the lens, among or afterwards, or other any position, it is continuous reliably the continue record of the elephant by camera lens, therefore, camera is just noted local and adjacent image on media.

It is contemplated that when grid device was packed camera into, grid device preferably was positioned at after the lens, contiguous and as close as possible film plane, synchronous with camera shutter, or replace shutter, or the film gate of packing into.

In various forms of the present invention, a plurality of angles of visual field are obtained and record by film, then, a plurality of angles of visual field of noting can be changed subsequently, so that comprise local and the adjacent angle of visual field, this can recognize by machinery, electricity one light, electric or other device is realized, for example cuts apart mixing etc.

It is contemplated that, in camera, can use the film or the tape that have programming grid or gap, to simplify the record facility.In another kind of form of the present invention, it is contemplated that, can adopt display unit to mix a plurality of angular fields with visual teasel root pattern.For example, can use liquid crystal display, the certain speed in image Segmentation line or gap crosses liquid crystal display, forms dynamic raster.
