Description
The present patent application is the No.08/164 of the application in 9 days Dec in 1993 of unexamined simultaneously, the partial continuous application of 507 applications.
The degree of depth that the present invention relates generally to two-dimensional image strengthens, the particularly use of optical filtering device, and the frame region that can make two-dimensional image and limit image looks like with respect to the observer and exists along the Different Plane in space.
Though the mankind can see three-dimensional video naturally by stereoscopic vision, the image that most of electronics and optics form is two-dimentional at occurring in nature.For example the printed matter of commercial TV, photo and lantern slide are two-dimentional.Can obtain a lot of benefits by the technology of seeing three-dimensional image from two-dimensional screen, comprising the understanding that technology shows certainly and improving with the amusement is the entertainment effect of purpose program.
Various technology are known and be used for producing at two-dimensional image or on two-dimensional screen the 3D vision effect.A kind of direct method is the image that record is seen by two lens, the glasses that have filter are provided to the observer, this filter only provides a kind of perspective selectively for every eyes, so can produce deep vision according to the key point that is used for original record.The synchronous liquid crystal shutter of electronics is in being commonly used in the observation glasses relevant with the visual image of true stereo record.Real in addition three-dimensional visible technology also may be used on the image that comprises photo.
In order to see real three-dimensional image, must use the stereoptics register.Therefore, must provide the complex appts of the optical element, register and the visual device that comprise separation, to satisfy the true reappearance of the difference perspective that is sent to two eyes of observer.The needs of the synchronous and raising bandwidth that this complexity has caused better and more complicated (under the situation of true three-dimension).In order to realize above-mentioned extensive television system, also need the infrastructure of now using in television broadcasting (infastruction) is carried out basic variation, comprise that the medium to being used for vision signal and Film Recording now changes.
Complicated needs development illusion or the false stereo technology and the device of causing of cost that increases and true three-dimension image, in general, this technology or device utilize simple eye or two-dimensional image produces the three dimensional illusion that the observer can experience.These devices will be taken all factors into consideration between the control that all necessary hardware that provide and true three-dimension image needs, but in fact when only having two-dimensional signal to provide, need the synthetic three-dimensional image of observer.
Causing three principal elements of deep vision is parallax, perspective and visual angle.
Parallax is separately to be caused by two eyes.When watching identical scenery, every eyes produce different slightly perspectives, and this aspect is very important in the formation of true three-dimension image.
Have an X-rayed in other words that linear perspective is included in each image, its characteristic is by performance three-dimensional body and the decision of the depth relationship on two-dimensional surface.
Not being both of visual angle is observed like this, and the left hand edge part that appears at the scenery in the visual field of left eye is not but in the visual field of right eye, and the right hand edge that appears at the scenery in the visual field of right eye is not partly in the visual field of left eye.These difference are separately to be produced by two eyes.
When not having parallax, promptly when handling all two-dimensional images, just need utilize remaining two factor, on two-dimensional image, to produce three-dimensional sensation.Utilize the effect at perspective and/or visual angle many more, will produce the tangible more degree of depth image.
Acting on parallax on the 3D vision increases with distance and promptly reduces.When scenery be between certain distance so that two eyes the interval approximately less than sighting distance 1% the time, the effect of parallax is actually non-existent.The influence at perspective and visual angle becomes primary variables, and brain is learned by lifelong distant surveillance experience, has ignored not existing of parallax, and determines the position of space object with perspective and visual angle.
The 3D vision of against vacuum, the separation of observer's eyes is introduced parallax in the scenery of observing.The partial action of parallax can cause the deviation of a scenery image and another scenery image, so for left eye, the object of image center can be with to the skew of the right at center, for right eye, the object of image center can be offset the left side to the center.The horizontal departure that different distances has in various degree produces, then close object than away from object bigger deviation is arranged.
On the contrary, two-dimensional image does not have above-mentioned deviation information.But, by by two slightly the locational same image of varying level offer two eyes simultaneously, can introduce deviation artificially.If utilized above-mentioned technology rightly, then make the muscle of eyes concentrate on the plane in the space different, thereby obtain an image with the true planar of throwing, this image makes the observer seem to see the scenery of a three-dimensional.
In order to obtain above-mentioned false stereoscopic image, can use electronic installation, for example, the application number of unexamined is No.07/873 in me, in 400 the application, described the electronic package that is operably connected with input signal source and display device, this assembly can carry out horizontal delay and scanning adjustment to the alternating field of television image.Vertically size and brightness also will be adjusted the vision that strengthens three-dimensional with further.A secondary liquid crystal glasses of operationally connecting with this assembly forces every eyes only to see of two alternating fields.Also can use the active optics device to produce false stereoscopic image, application number as unexamined in me is No.08/106, as described in 258 the application, wherein two of two-dimensional image have the picture of horizontal departure to be sent to the observer who wears special spectacles, so can see 3-D effect on two-dimensional image.
Although, electronics of learning in the application by the unexamined of above-mentioned reference and optical technology handle two-dimensional image obtain three dimensional illusion with aspect be effective, but, in both cases, make pattern distortion by this way, if possible, be difficult to enjoyment for the observer who does not wear special spectacles and watch image.In addition, having under the situation of electronic installation especially, the adjustment level, vertically the required circuit of size and brightness is very complicated, has exceeded the scope of the device that most consumers can bear.Although optical devices are active, thereby it is not too complicated, but because the observer who does not wear glasses can not appreciate the two-dimensional picture as the image of two skews, so provide switchgear to change position element (ooptical redirection) and make light change position element (opticalredirection) invalid, so increased complicacy to drive light.So, still need a kind of technology, utilize this technology can on two-dimensional image, see the effect of the three-dimensional or the degree of depth by mode cheaply.Utilize this technology, one group of observer can see the enhancing of this degree of depth, if they are when wanting to see, and another group observer, if they when also wanting to see, can see identical image simultaneously but not be the three-dimensional images of sensation.
The invention provides a kind of simple low-cost device, this device can produce the vision of the degree of depth on two-dimensional image, the mask that preferably includes the light blocking frame or arrange along a left side at least or the right of image.This frame and mask should with image at grade, and can by coating, silk screen or even the electronics blanking form, just passable, preferably opaque as long as mask covers light.According to the present invention, the fillet of first material arranges vertically that along the right hand edge of the image on the close left side fillet of the inward flange of frame and the second smooth filtering material is vertically arranged along the inward flange of the frame on also close the right of left hand edge of image.The left eye that the first smooth filtering material layer is arranged in the observer with have described first and the image of the described band edge frame of the vertical fillet of the described second smooth filtering material between, the second smooth filtering material layer is arranged in observer's right eye and comprises between the image of band edge frame of vertical fillet, make image seem to seem to draw back from frame, then on image, produce the vision of the degree of depth, seem that frame has produced the observer and can observe this visual window, and in fact the image and frame in the same plane.Material between eyes and image and frame preferably is contained on the frame.
In a preferred embodiment, first and second fillets of the first smooth filtering material are vertically arranged along the right hand edge of image and the outermost left hand edge of frame respectively.First and second fillets of the second smooth filtering material are vertically arranged along the left hand edge of image and the outermost right hand edge of frame.The first smooth filtering material layer be arranged in observer's left eye and have the first and second smooth filtering materials the image of first and second fillets between, the second smooth filtering material layer is arranged in observer's right eye and comprises between the image of vertical fillet of the first and second smooth filtering materials, this combination makes image seem to seem to draw back from frame, and frame seems to seem to come up forward with respect to image.Further strengthened the visual effect of the visual degree of depth.Material between eyes and image and frame also preferably is contained on the frame.
The feature of the first and second smooth filtering materials is coated and can produce the light compensating effect when being used for observing simultaneously when them, so the position of the first and second smooth filtering materials can exchange still can reach the effect that needs.In a preferred embodiment, the first and second smooth filtering materials are the mutually perpendicular polarization filter of polarization axle.Also can use other light filtering material that comprises complementary color.
Above-mentioned image can be any two-dimensional image, comprise traditional televisor, also have photo, movable picture film projection, magic lantern projection, color separated printed matter, no matter be the projection television image that produces by back or preceding projection, and image can be black and white or colored image.And, providing with image under the situation of frame, provide as a part of the present invention as the frame around the image under the situation of the televisor that just has frame or baffle plate around the screen or monitor is unnecessary.Mask also be used in image around, for example the bottom and upper segment edge of rectangle image has radian or crooked shadow mask can further strengthen the degree of depth and vision clearly.

The invention provides a kind of simple low cost device, be used on two-dimensional image, producing plastic, no matter and how this two-dimensional image is realized and shown.In order to realize the sensation of this three dimensional depth, around image and observer and have between the image of relevant filter and used optical filter, so make image and the zone around image Different Plane on the space occur.In most preferred embodiment, this optical filter is to have the polarized material that can be used for providing the polarization axle of different images to each eye, will describe in detail below.Also can use comprising of other kinds of complementary color filter and other similar optical filter.In order to reach comfortable purpose, the filter that is between spectators and the image preferably is placed on the framework of glasses, as long as every independent corresponding eyeglass of eyes, filter also can be placed on other object.In conjunction with optical filter, now mask and the frame technology that helps to promote the illusion effect on two-dimensional image is described.
Fig. 1 shows United States Patent (USP) 3,597, the 042 disclosed existing apparatus that makes picture produce the polarisation filter of obvious 3-D effect at Favre.The plane picture of being represented by an ABCD is placed on spectators' front, and two eyes of spectators are represented by point 1 and 2,1 expression left eye wherein, 2 expression right eyes.Vertically band AEFD in zone is positioned at the left side of picture, and the zone band GBCH of same size is positioned at the right side, and they all are coated with and are coated with polarized material 3 with different polarization axle and 4 fillet.In the figure, for example, fillet 3 has horizontal polarization direction, and fillet 4 has vertical polarization direction.Two identical filters 5 and 6 for example are positioned at the front of spectators' eyes with the form of glasses.The polarization direction that polaroid 5 has is vertical with the polarization direction of fillet 3, and the polarization direction that polaroid 6 has is vertical with the polarization direction of fillet 4.Under such condition, left eye 1 can not be seen the zone band AEFD of picture, but can see zone band GBCH.In addition, right eye 2 can be seen zone band AEFD, but has been blocked effectively owing to cross polarization by the zone band that GBCH represents.By Favre disclosed selectable shelter to spectators feel to be him in the front of the image at the back side that object is discussed, this discussion object is positioned at the back on the plane of original image.
Yet, can also find that the Favre technology only produces soft depth preception, and this technology is confined to special application owing to the needs of light and other consideration.In general, the limitation of Favre technology is owing to do not use frame around image, so the polarization bar is only regarded as opaque or black region at a vertical edge with respect to the image of every eyes, rather than is present in the both sides of the image that offers every eyes.Add the frame and/or the mask that describe below, the effect of Favre technology can improve significantly, and this frame or mask make frame or the border around the image present forward trend, so the frame effect is significantly improved, tangible deep vision are arranged on two-dimensional image.In addition, use above-mentioned frame and mask, played the effect of and a left outward flange other cover optical filter right, make image seem to move back fartherly at three dimensions from its plane at frame.
Referring now to Fig. 2, Fig. 2 shows the televisor of representing with 210, and this TV has along about the television image the vertically polarized material 212 of edge placement and 214 fillet.Though following discussion is used video pictures as an example, be appreciated that technology of the present invention and scope are not limited to the two-dimensional image of such generation, and be equally applicable to the image that throw the front and back, also have photo, movable picture film, flat pannel display (as liquid crystal display), high-definition television demonstration, lantern slide, printed image or the like.
One secondary visible mirror 220 is used for watching the image 211 on monitor 210, and the polarization axle of two eyeglasses of visor 220 meets at right angles mutually, represent as dotted line A and B, these polarization directions be with Fig. 1 in fillet 212 and 214 polarization direction on be complementary.Much less, the angle of polarization direction is unnecessary to be the oblique angle, and can be vertical, level or arbitrarily angled as long as blur for right eye through filter 214 along the zone of the image on image the right, the remaining image region that is covered by filter 212 is visual, for left eye opposite situation is arranged then.
Improvement of the present invention comprises the frame and the mask that can be used in combination with the fillet of two other polarized material 216 and 218.These two other fillets are placed along the vertical outward flange of televisor or framework, so the polarization fillet can extend in outside space along the edge.The polarization fillet 216 and 218 of these two ragged edges has formed wing limit, can stretch out from the anterior angle of televisor.This stretch out have three effects at least:
1. but back lighting fillet 216 and 218 is to guarantee from transparent to opaque complete transmission.
2. fillet 216 and 218 opposite with the fillet polarization orientation near the TV picture edge polarization of each outer side slat of adjacency.
3. produced variation on the perspective of above-mentioned 1 and 2 the vertical frame that is combined in the TV picture, frame is stretched out forward from the plane of television image, so formed virtual square frame in the space.
Fig. 3 A shows the left eye that is present in every eyes and the parallax of right eye.Be interpreted as two " images " in spectators' the brains, seem that " W " orientation and " B " and " F " orientation in " F " orientation and the left eye in the right eye determined that the position of object, this object are on the plane and the plane between the corresponding TV image plane of observation." B " and " F " orientation in the right eye and " W " in the corresponding left eye are orientated the position of the object of determining with " F " orientation simultaneously, this object is on plane of observing and the plane between the TV image plane, if the width on the left side (" W ") is not equal to the width (" W ") on the right, the plane of image is just not vertical with the plane on televisor surface.If the size of the left side (" B ") and the right (" B ") polarization fillet is unequal, the plane that the TV image plane is positioned at is not on definite plane, plane real or that televisor stretches out.Naturally, certainly the observer moves with respect to televisor, and the square frame plane of stretching out also can be moved so.
The present invention is not limited to application image or televisor, also can be used in various projection systems, comprises and the forward and backward projection system of single and a plurality of lens image systems, can also be used in the transmissive system that comprises film-type.
Fig. 3 B shows traditional screen 350 how rim area 352 is housed, and rim area 352 is at least along vertically being placed on the fillet 354 of each rim area 352 and right hand edge and the left hand edge that square frame 350 delimited on wing limit 356.In the drawings, as in Fig. 2, oblique line is used to refer to polarization angle, so when the observer put on glasses 220 shown in Figure 2, the image that shown backward or stretched out forward on screen 350 had produced the degree of depth of the present invention and strengthened effect.
The image that occurs black picture or band wing limit when the front surface of televisor by in the past or from after illuminate, then to strengthen process very effective for the degree of depth.If the application back lighting is then very simple, resembles and be placed on televisor with televisor wall front with distinct contrast simple.Under the common illumination condition that the wall of white or light colour runs into, play good effect when seeing TV.Televisor can be furnished with soft back lighting, brings picture light and shade difference in distribution, perhaps can use to be installed in above the televisor or the single reflecting surface of back.When the back lighting inconvenience maybe can not provide, can use mirror in back, wing limit.
No matter be back side illuminaton or directly illuminate that light colour is with reference to the planimetric position that influences the space frame.When light colour with reference to when the polarization wing limit, the plane of frame is in spatial movement.Interaction between polarization wing limit and light colour reference has produced another kind of illusion.An image becomes the other factor of depth preception with respect to the change of other visual brightness.Above-mentioned can easily finishing by the filter of the heterogeneity density on viewed spectacles.
Have the polariscopic polarising glass of non-homogeneous must be used for illuminating configuration and balancing each other of wing limit 216 and 218 irradiations, if do not note mating then may weaken the degree of depth degree that is created on the scenery.In addition, the ratio of the width of television image edge polarization fillet and the width on wing limit can influence the degree of depth degree that is created on the scenery, and the distance between wing limit and the light colour reference also can influence the degree of depth degree that is created on the scenery.The influence of all above-mentioned factors must be carefully balance in addition, reach maximum with the depth dose that when guaranteeing that eyes are comfortable, produces by this degree of depth intensifies process.
Can produce the further degree of depth and strengthen effect.Mask or " shade sheet " are added to the significant effect of meeting generation in the structure shown in Fig. 2,3A and the 3B, and this can observe when increasing or the former depth preception that is produced by polarization technology is provided.The shade sheet can be by the forming of different shapes, but seeming shown in Fig. 4 A is very comfortable and effective to televisor.Fig. 4 B-4C shows other mask, owing to have a frame, the shade sheet is available or can " wing limit ".
In simple form, the shade sheet can be used as mask blacking or the silk screen and directly is added on the inside of the outside surface of kinescope or rear projection type screen of TV set.For the television system of preceding porjection type, can be pre-formed or shelter TV tubulose screen in a manner described.In addition, in fact Bao opaque mask also can be added on the barricade of teletube, is contained between teletron and barricade (flanged plate) device, perhaps installs to the front surface of televisor itself so that can unload easily.Same mask can install to the projection television system, so mask can be taken away when needing.By being cancelled, required form understands its least noticeable shade sheet of electricity generation on television image.This just makes when needed the shade sheet is carried out remote control.
The purpose of mask provides a kind of shade sheet that is added to the geometric configuration of polarization process, and simultaneously mask needn't limit the visual angle that appears in " window " type system (referring to patent No.3,582,691 and 2,408,050, see Fig. 5).So mask is when the inside of the surface plate of teletube, effective method is on the electric shade sheet, yet all other method is also all effectively same, because they are located immediately at the outside surface of the panel of teletube, in fact not have the thickness of being correlated with.
Fig. 5 shows the window of the reality between image plane and observer.The effect of this window is the visibility degree that reduces to the image that reaches observer's eyes.The attention right eye can not be seen a L2, because blocked by plane L1, and right eye has the unrestricted image of a L2.Right eye can not be seen a R2 simultaneously, because blocked by plane R1, and right eye has the unrestricted figure of a R2.
By because the scenery around the observer, window limit the observer observe the ability of image edge, should " window effect " provide the illusion on the degree of depth,
The major advantage of actual window is can limit the visual field by window itself, and the visual field is too narrow and can not be used for numerous observer's observing scenes.Window itself becomes the object of the reality of the visual front that is present in protrusions space simultaneously.
Fig. 6 shows the effect that produces by the shade chip technology.The image that right and left eyes is seen is complete or almost completely identical or opposite, but, the geometric configuration of mask forms image border with the polarization fillet, seem to seem front on the two-dimensional image plane, and the image that the degree of depth strengthens seems to seem to be positioned at the back of two-dimensional image, feel that these two kinds of illusion that can add altogether, so improved the tangible degree of depth that is created on the picture.
Owing to be present in the angle of four jiaos of TV set image, the edge of image seems to seem the front at televisor.Brain is interpreted as a kind of sign together to the width that the slope on border and picture dwindle in the perspective ratio, and promptly the border of scenery tilts towards end point and observer.So pattern system determines that the edge is on the plane different with image.The frame that is formed on impression in observer's the brains and is around TV screen and the screen is three-dimensional.
Can strengthen technology with regard to drooping other degree of depth, as long as notice guaranteeing that this technology will add rather than remove.Front surface in TV screen has been drawn dotted line, and this dotted line tilts to assemble towards the end point of certain distance.These boost lines help to sharpen understanding, and promptly TV screen is outwards to reduce gradually towards spectators, and Fig. 7 shows such example.
Further strengthen the degree of depth other method be on the edge of the shade sheet on the inclined surface that limits image, to add the polarization fillet.For example Biao Mian top is transparent for left eye, and the bottom on surface is transparent for right eye, and Fig. 8 shows this situation.If necessary, same fillet can be added to the upper and lower of frame.
The frame 901 that has 902 and 910 parts is again being watched in the process with glasses with can strengthening the degree of depth, and in fact fillet 902 is positioned on the position shown in the dotted line 904.Wing limit 910 is positioned on the position shown in the dotted line 912 simultaneously.Yet when suitable mechanical switching device was arranged, fillet 902 may be along axle 906 deflections forward shown in the arrow 908, so it is disappeared from observer's visual field field.Simultaneously, wing limit 910 can be along axle 914 rotations as arrow 916 indications, so also disappear from observer's visual field field.
The device that these light filtering materials are selectively got rid of, many selectable schemes are arranged.For example, the right hand edge of screen 900 is looked in Fig. 9, comprise outermost the right wing limit 921 whole regional 920 can be around the rotation backward of the axle 922 shown in arrow 924, rotation an angle of 90 degrees or bigger, whole regional 920 can be fuzzy in picture, or even be hidden in after the screen 900.Also may be according to surrounding environment, comprise fillet 931 and wing limit 921 and the rim area between them 933 whole zone can around along as the axle 932 of arrow 934 indications to post deflection, caused forming the zone that dotted line 936 is indicated.And rotatable 90 degree that surpass in whole zone are so be hidden in after the screen 900 all these compositions.
