Embodiment

The invention is characterized in, even the size of imaging apparatus and the indication range of 3 d display device and the different occasion of picture dimension at stereoscopic camera, still can share stereopsis data, for distance perspective and the size of all stereopsis are commonly identified, when photography, set with reference to window.And, this is photographed as visual field frame (frames images of left and right) with reference to window, as demonstration and necessary benchmark stereopsis data and exporting.And, showing side, by standard stereopsis data being presented in the standard-sized picture with reference to window equivalence with the side of photographing, can verily reproduce third dimension.

For example,, in Fig. 2, with reference to window W _refwidth be defined as W _w;

By projection in imaging apparatus with reference in window picture I _refwidth be defined as W _s;

Standard-sized display frame width is defined as to W _d;

Now, photography multiplying power r is r=W _s/ W _w

Show that multiplying power R is R=W _d/ W _s

R * R=1 so.

Can be regarded as: in above-mentioned mathematical expression, can not consider the size of the width Ws of imaging apparatus, easily the output image data of stereoscopic camera be carried out to the datumization of standard stereopsis.

Embodiment 1

Fig. 1 is the concept map of stereos copic viewing of the present invention.If using illustrated large stereo TV (the wide 1800mm of display), as the TV of standard size display frame, the display frame of each size is configured to illustrated relation with it.

Fig. 3 is the size of presentation graphs 1 and the figure of configuration relation in more detail.But Fig. 3 is relatively actual dimensional ratios, becomes large dimension scale along with approaching of the position with observer.It can avoid mixing in mapping.

In Fig. 3, from observer's eye to the distance L that illustrates the boundary line of left and right juxtaposition indication range and overlap scope _xfor L _x=L ₀/ (1+W _p0/ B) relation, if L ₀=2500mm, W _p0=1800mm, the size B=58mm that eye is wide,

L _x=2500/ (1+1800/58)=78.04mm;

If the size B=72mm that eye is wide,

L _x=2500/ (1+1800/72)=96.15mm.

In the juxtaposition indication range of left and right, need for separating the dividing plate in the visual field of left and right, actual to view and admire apart from 75mm left and right be basic limit.In addition, 75mm is very approaching apart from comparing with photopic vision, so need visual accommodation magnifying glass, the focal length of magnifying glass is slightly greatly more fine than sighting distance, and the focal length of the magnifying glass using under this occasion is about 80mm for suitable.

In addition, B is for each observer for the wide size of eye (three-dimensional basis), how much understand some difference, but viewing and admiring the large occasion (overlap indication range) of distance, the respective point of infinity picture between left and right every with the wide size B of eye number difference can ignore.

And in the juxtaposed indication range in left and right, the surplus of the difference of eye width dimensions B is few, still, by regulating the interval of visual accommodation camera lens, its poor mitigation.

The picture interval of left and right, picture interval is the eye wide interval B of the left and right shown in Fig. 3 and arrives standard-sized display D ₀distance L ₀for following relation.Be disposed at distance L arbitrarily _ndisplay D _npicture space D _pNfor D _pN=B (1-L _n/ L ₀) value.

Left and right picture width W separately _p0with audience eye distance proportional, but enter left and right separately eye light clip display D ₀illustrated visual angle α identical, so the picture width on separately apparent shown in Fig. 3 is W _p0=W _p1=W _p2relation, appear as formed objects.

As described above, on the TV of standard size display frame (the illustrated large-scale TV of Fig. 1), standard stereopsis data are shown as to the setting that is related to shown in Fig. 1, thus, the overlap indication range showing from the doubling of the image that left and right is used, to having left and right separately all indication ranges of the left and right juxtaposition indication range of display surface, can be used common data.In this occasion, in illustrated display separately, standard stereopsis shows that data are only with left and right defined terms configuration (position and width) demonstration separately.

Fig. 2 is the key diagram of stereoscopic camera of mechanism of obtaining the stereoscopic image data of relation shown in Fig. 1 configuration.Fig. 2 (a) is and the identical state diagram of state of the stereos copic viewing of Fig. 1 that Fig. 2 (b) is the graph of a relation as the occasion of stereoscopic camera.Now, by the illustrated equal display E with reference to window of Fig. 2 (a) _refas the display of the TV (the large stereo TV that Fig. 1 shows) of the standard size display frame of Fig. 1, on the stereoscopic camera of Fig. 2 (b), set with reference to window W _refif, using the interval of the phtographic lens of the left and right of video camera as the wide size B of eye, from the equal display E with reference to window of Fig. 2 (a) _refthe eye E separately to observer's left and right _l, E _r, with the wide W from Fig. 2 (b) _wwith reference to window W _refto left and right phtographic lens L separately _l, L _rpresent conjugate relation.Therefore, in the angle of visibility α separately of left and right, the view data on the imaging apparatus of configuration equates with the occasion of people's reality at the TV (illustrated large stereo TV) of the standard size display frame of observation Fig. 1.The size (width) of the imaging apparatus configuring in angle of visibility α in addition, is determined by the position of the optical axis direction of configuration imaging apparatus.

In Fig. 2 (b), the width W of imaging apparatus _swith W _s=W _w* f/L calculates.In addition, the interval of the imaging apparatus of left and right (picture interval of inverted image state), i.e. illustrated D _swith D _s=B (1+f/L) calculates, larger than the interval=people's of the phtographic lens of left and right the wide B of eye.

On imaging apparatus, the picture of projection is handstand state, in order to make it upright, if at the position Rotate 180 degree separately of left and right, and the picture interval of left and right, that is, picture interval (showing side=erect image state) is less than people's the wide B of eye.In addition, shown in Fig. 2 (b) with reference to window W _refwith by left and right separately phtographic lens principal point, clamping with reference to window W _refwindow W _wtwo triangles (two triangles that a part is overlapping) of forming of line, principal point with following two triangles by left and right photographic lens is separately similar type, and described two triangles are the line at two ends of imaging apparatus S and the triangle of the face of imaging apparatus formation itself separately of the principal point clamping left and right by left and right phtographic lens separately.In addition, the assembly of left and right take illustrated center line O as line of symmetry symmetrical, so take scheme in the center line O of paper folding as fold line, the optical axis Ф (L) of left and right is consistent with Ф (R), left and right is overlapped.Therefore, the stereopsis of photographing according to the stereoscopic camera of Fig. 2 (b) in the same frame position of the TV of the standard size display frame of Fig. 1 (illustrated large stereo TV) with timesharing alternately or overlapping the mirroring of while such as polarisation, according to visual field separation glasses, if the eye with left and right is watched respectively picture separately for left and right, it is wide that the respective point of infinity picture demonstrates people's eye naturally.Therefore, can reproduce the stereopsis of optimum state.In addition, in order showing in standard-sized same position, not need special gimmick, only the picture on the imaging apparatus S shown in Fig. 2 (b) will need to be shown to the picture width W of multiplying power with display D on the display of Fig. 2 (a) _dwidth W with imaging apparatus _sthe W of simple ratio _d/ W _smultiplying power show.

In addition, the left and right of the size separately shown in Fig. 1 picture width separately, with the configuration distance of display unit separately and the ratio of the distance of TV to standard size display frame decide (in Fig. 3, L ₁/ L _o=W _p1/ W _p0).Therefore, left and right is simple ratio with display frame width separately, therefore easily calculates.

And, as shown in Figure 1, stereopsis is in all scopes, the respective point of infinity should be shown by the eye wide interval with people, therefore, infinity=eye is wide=the optical axis spacing of the phtographic lens of left and right, by the light of respective point of infinity of photographic lens of left and right that enters stereoscopic camera for being parallel to each other, therefore, the respective point of projection infinity picture on imaging apparatus equals optical axis spacing.Therefore, any display sizes no matter, between the display frame of left and right, if wide setting of eye by the interval=people of the respective point of infinity, only need be set in the optical axis center correspondence position of the phtographic lens separately of the left and right on the imaging apparatus separately of left and right the width interval location of equal of the upper left right septum of display frame and human eye.That is, the 3 d display device of any picture dimension no matter, the optical axis separately of left and right of stereoscopic camera of take is benchmark, between the left and right of regeneration picture, the optical axis interval corresponding interval of the left and right of camera assembly shows with the size equating with human eye width.

Fig. 4 is for changing to the phtographic lens of the video camera of the state shown in Fig. 2 the state diagram of wide-angle lens occasion, for the subject of same widths is photographed with the form of wide-angle, object distance is set less, in addition, for imaging on the imaging apparatus of same size, the focal length of photographic lens is shortened.As shown in Figure 4, in the occasion of changing the phtographic lens of short focal length, in stereos copic viewing, left and right view field carries out consistent distance and also shortens.If actual scene is looked at straight with bore hole, the visual field frame W of the position that dotted line shown in Fig. 4 represents _ref' contain the occasion of infinity (photo photography infinity), in stereos copic viewing, it is that impossible (people is when watching outdoor scene that the object of close shot and the object of distant view are watched simultaneously, often instantaneously watch the narrow visual field, in brain, process, actual can watching, but can bring the fatigue of optic nerve).But, at this state, (phtographic lens with short focal length is photographed, the visual field of left and right is consistent at short photo distance) the stereoscopic TV of the standard size display frame recorded at Fig. 1 of the video camera stereoscopic image data of the photographing occasion of watching, the state of stereos copic viewing is good.Set the dotted line shown in Fig. 4 shown with reference to window W _ref' in, physical presence as window, if from this window direct-view outdoor scene, the parallax of close shot and distant view is very large, therefore in stereos copic viewing, it is impossible that the fusion of carrying out left and right view field is watched, if but these stereopsis data are watched with the display unit separately of the set condition that Fig. 1 was recorded, the dotted line of Fig. 4 show with reference to window W _ref' can watch that illustrated solid line shows in the mode zooming out with reference to window W _refposition, therefore can carry out common stereos copic viewing.Therefore, the use of wide-angle photographic lens can approach subject and photograph in the photography in narrow place, is therefore favourable.

Fig. 5 is contrary with the occasion of Fig. 4, is the example of the long camera lens of focal length.In the long situation of the focal length of phtographic lens, in the photography visual field of left and right, in the farther position of distance of viewing and admiring than standard, carry out unanimously (illustrated dotted line position).But, the in the situation that of this occasion, if viewed and admired with the display unit shown in Fig. 1, in fact, with dotted line, show, be positioned at remote location with reference to window W _ref" can closely arrive the visual field frame W of actual displayed _refposition and approach watch.

According to the explanation based on above-mentioned Fig. 4 and Fig. 5, zoom lens's use also can be implemented certainly, the focal length of photographic lens changes in any case, so long as the width of the corresponding imaging apparatus of standard size display frame that the formula shown in above-mentioned Fig. 2 is calculated and interval get final product (width of imaging apparatus is used slightly large element in practice, can set read range).And, even if change the focal length of the phtographic lens of stereoscopic camera, as long as view and admire the stereoscopic TV of side, such as in advance illustrated each condition of Fig. 1 being set with certain state.This be because, the light that incides the phtographic lens of left and right from the respective point of infinity is parallel to each other, meanwhile, the optical axis spacing of phtographic lens is set as the width of human eye.For this reason, the interval of respective point and the width of human eye of infinity projecting on the imaging apparatus of left and right equates.

Even if identical stereoscopic camera is changed to the occasion of the focal length of photographic lens, the width of pair of right and left imaging apparatus and be spaced apart certain, so the focal length of photographic lens in the occasion changing, the consistent photo distance in the visual field of left and right changes.In stereopsis, no matter common which type of situation, preferably the consistent distance of left and right view field does not enter the photography state in the photography visual field with near object.In stereoscopic camera, even if for example view finder is carried out in the situation of stereos copic viewing, in the visual field of left and right, consistent distance is with closely, object falls into the photography visual field, or not fall into and carry out visual confirmation be difficulty very, still, the picture separately of the left and right by the calibrating pattern shown in Figure 11 and view finder carries out overlapping demonstration, thus, improve visual confirmation.

Binocular projector 60 shown in Fig. 6 has pair of right and left projection lens 61L and the 61R setting as people's eye wide interval.And then, width W _ddisplay 62L and 62R the interval D slightly larger than the interval of the projection lens of left and right 61 is set _d, thus, the projected picture that left and right is used is in the screen S with standard size display frame equivalence ₀on carry out consistent.Thus, only on the screen by any distance, focus, projected image, to show with state the same terms of Fig. 1 demonstration, if observed from suitable viewing distance, can obtain good third dimension.

If the position of this display 62L and 62R is positioned at the position of illustrated projected angle θ, the wide W of display 62 _dsize do not limit, until the screen S of projection lens ₀～S ₃, in whole lens distance, with the focal length f of lens and deciding with f+ ⊿ f of focal adjustments Liang ⊿ f.Therefore,, if the illustrated projectional angle θ of Fig. 6 and the illustrated photo angle α of Fig. 2 (b) are set in to equal angular, there is no need the width W of the shown imaging apparatus S of Fig. 2 (b) _swide W with the display 62 shown in Fig. 6 _dbe set as same widths.

But, in diagram, in fact, the setting position of projecting apparatus (distance) with view and admire distance equate, itself interacts projecting apparatus.It can be by arranging apart from (screen S projecting apparatus ₀～S ₃) be set as n (n > 1) doubly and solve.Therefore, the relation of the projected angle θ illustrating in preceding paragraph and the illustrated photo angle α of Fig. 2 (b) does not become the relation of θ=α, but θ < α.

In Fig. 7, for the binocular projector that two projecting subassemblies are carried out to juxtaposed Fig. 6 changes over the key diagram of the occasion of single component.The image that the display 73L of the illustrated left and right of dotted line and 73R use the upper left and right showing is according to the illustrated left and right of dotted line projection lens 72L and 72R separately, unanimously with the Width of left and right on screen 71 carries out imaging.Be not limited to the optical axis spacing of the projection lens of left and right is left to 65mm and set with people's the wide size equating of eye, and left and right projected picture is carried out to correspondence on screen 71, be larger than optical axis spacing because of what the interval of the display 73L of left and right and 73R was set.

Triangle a, O that in Fig. 7, dotted line shows _(R), b and triangle f, O _(R), e is with an O _(R)as symmetric points, be similar figures, same, triangle a, O that dotted line shows _(L), b and triangle d, O _(L), c and solid line the triangle a, the O that show _(C), b and triangle h, O _(C), g is respectively with O _(L), and some O _(C)for object-point is similar figures.Therefore, line c-d, g-e separately, e-f equate.Therefore, the projection lens 72 of the illustrated left and right of dotted line _(L), 72 _(R)if move to 72 shown in the solid line of intermediate position _(C)position, 72 shown in display dotted line _(L)and 72 _(R)with centre position with solid line, represent 73 _(C)overlapping.In addition, display 73 _(L)and 73 _(R)if the image timesharing that the left and right of upper demonstration is used alternately shows based on projection lens 72 _(C)and display 73 _(C)the left and right image of employing list projecting subassembly, with by two of the left and right juxtaposed projecting apparatus of projecting subassembly be equal to.And, on screen 71, carry out display 73 corresponding to the respective point of unlimited distance picture of imaging with the optical axis spacing equivalent size of the projection lens of left and right _(L)on picture X _land 73 _(R)on X _r, at display 73 _(C)upper with the → position relationship that shows, carry out Alternation Display.The reversion of position, left and right is because the picture of projecting apparatus is shown as the picture of handstand in the display that represents original painting, and projection lens is reversed.

In addition, by infinity as respective point with the symmetrical position illustrating, be that the state of stereos copic viewing represents in the mode of watching at picture middle position, but actual infinity looks like to be not limited to picture central authorities, at this, is for convenience of description and the mapping of carrying out.But, from the light ray parallel of the identical point transmitting of the object of infinity, be incident in right and left eyes.Therefore,, even if be considered to show with graphing method so, conventionally also can be understood.

Fig. 8 is the application examples of the holographic display device based on the illustrated single projecting subassembly of above-mentioned Fig. 7.Holographic display device 80 (stereoscopic TV), for the image that DMD81 is shown carries out the rear projection mode of projection on transmission-type screen 84 (the inside) by projection lens 82, arranges Polarizer 83 before projection lens 82.At this state, if the image timesharing Alternation Display of left and right being used according to DMD81, in transmission-type screen 84, the image that left and right is used is with the polarisation of equal state, and Alternation Display in chronological order.If view and admire this stereopsis with aforesaid stereopsis viewing glasses, can carry out the stereos copic viewing of separated left and right view field.

In addition, using LCOS to replace the occasion of the display element of DMD, is polarisation from the light of LCOS reflection, therefore are unwanted (claims 10) at the illustrated Polarizer 83 of Fig. 8.

Fig. 9 is holographic display device 90 (stereoscopic TV), at the projection lens 92 of DMD rear projection assembly 91 Polarizer 93 is set above, at its former configuration liquid crystal cell 94, and then, at its former configuration λ/4 plate 95, the image that the left and right of the stereopsis based on standard stereopsis data is used alternately shows on DMD91, simultaneously, synchronize and drive liquid crystal cell with the demonstration portrait of DMD91, the high speed shaft of relative λ/4 plate 95, take polarization direction as 45 degree or-45 degree the incidents that are related to control, thus, seeing through, on screen 96, by stereopsis, the rotatory polarization with left-handed or dextrorotation alternately shows.In this occasion, by adopting rotatory polarization glasses to view and admire, even if glasses tilt, can not produce interference yet.(claim 11)

In addition, in said apparatus 90, if replace DMD, use LCOS, do not need Polarizer 93.(claim 12)

In television broadcasting, with in stereoscopic camera, preferably, in the photography visual field that observation demonstrates in stereos copic viewing view finder, also can look at outdoor scene straight.For realizing so stereos copic viewing view finder (monitor), such as, in 12 inches of wide liquid crystal display shown in Fig. 1, stereo tv camera is installed.12 inches of sizes belong to larger classification as the monitor of video camera, as shown in the figure, can watch from the position of 350mm.In this occasion, the picture of left and right can replace timesharing and show.Meanwhile, from being installed on the synchronizing signal dispensing device transmission of display, synchronously use infrared ray.(diagram is omitted).And the left and right of the stereopsis viewing glasses in the visual field of separated left and right is provided with the identical Polarizer in left and right.And, liquid crystal board is installed before it.In addition, inclination sensor is installed on glasses.The light of the left and right alternately emitting from above-mentioned LCD is the polarisation identical and certain orientation.If the Polarizer of above-mentioned glasses is made as and the inclined to one side direction of light vertical direction of blocking LCD and emitting, the visual field of glasses left and right is closed and dimmed.The state in this visual field, according to being installed on liquid crystal board above, comes from incident light optically-active 90 degree of LCD or the polarization direction of 270 degree, and the visual field of left and right two directions all becomes out state, can be changed to the state that can become clear and observe.If synchronously send the infrared ray of information according to the demonstration portrait on LCD, on the liquid crystal board of installing at glasses, alternately apply voltage above, according to voltage liquid crystal, become tense situation, the polarisation of emitting from LCD maintains polarization direction as it is, according to the liquid crystal board of glasses, by shading, the visual field is dimmed., if according to infrared ray, synchronize with LCD meanwhile, alternately apply voltage on the liquid crystal board of glasses, the visual field of left and right alternately opens and closes, and watches the visual field of left and right of LCD separated, can carry out stereos copic viewing.In addition, the in the situation that of inclination glasses, the relative direction of the polarization direction of LCD and glasses is related to entanglement, has produced interference, still, controls and applies voltage, carries out revisal according to inclination sensor, thus, can prevent entanglement.In addition, in electronic image pickup device, view finder there is no need with video camera integrated.For example, the stereoscopic camera that the phtographic lens of pair of right and left and pair of right and left imaging apparatus form, if be connected with USB interface etc. with notebook computer, PC itself has just become view finder.

Figure 10 is an embodiment of above-mentioned stereo tv camera, and illustrated double dot dash line 100 is above-mentioned explanation with reference to window.This visual field that is video camera with reference to window essence, the visual field frame that the outdoor scene of photographing according to stereoscopic camera is set for imagination.In this imagination visual field frame, watch the state of scenery of outside identical with window such as from family etc., there is not frame in actual scenery, so photographer 104 not only can surmount stereo tv camera 102 and watch the photography visual field (illustrated with reference to window 100) by stereopsis viewing glasses 103, and, can look at the scenery outside the photography visual field straight.And if sight line is fallen on monitor 101, on monitor 101, (interior) can be with the stereopsis from watch same distance sense (though actual display size is different, but can so watch) with reference to window 100 same sizes.

The relation of the width of the monitor use display 101 of Figure 10 and suitable sighting distance, if be L in Fig. 3 ₁=350mm, left and right display frame width is separately illustrated W _p1situation under, W _p1=W _p0* L ₁/ L ₀

If W _p0=1800mm, L ₀=2500mm, the left and right wide W of display frame separately _p1for W _p1=1800 * 350/2500=252mm.

The picture interval of left and right, picture interval is with the D of Fig. 3 _p1meter, the D of above-mentioned mark _pN=B (1-L _n/ L ₀) in, D _p1=B (1-L ₁/ L ₀), if eye widths is B=65mm, D _p1=65 (1-350/2500)=55.9mm

The center distance of portrait display frame of left and right, picture interval is with the time interval of Fig. 3 explanation, by the time interval of the respective point of infinity picture, is the 65mm with the wide interval equating of human eye.In Fig. 3, D _p1(R) be right with picture, D _p1(L) be the left picture of using.Display D now ₁size (whole width) be: W _p1with D _p1add up to W _p1+ D _p1=252+55.9=307.9mm

Although this size is slightly larger than 12 inches, 12 * 25.4=304.8mm, its be by sighting distance itself with the numerical value of 10mm scale the situation of processes and displays, in addition, though in fact sighting distance how much watch from afar also no problem.

In addition, otherwise, if calculate sighting distance L from display sizes ₁, in Fig. 3,

L ₁＝L ₀(W _P1+D _P1-B)/(W _P0-B)

W _P1+D _P1＝12”＝304.8mm

If B=65mm

W _P0＝1800mm

L ₀=2500mm, sighting distance L ₁for L ₁=2500 (304.8-65)/(1800-65)=345.53mm.

And then for the visual confirmation of stereos copic viewing of the monitor of stereo tv camera is more prone to, the calibrating pattern using ordinate as main body is by the software overlapping left and right image that is shown in demonstration respectively.Figure 11 is the details drawing of monitor 101 of the stereoscopic camera 102 of Figure 10, at display 101 (display D ₁) upper,, with on the overlapping position of portrait difference calibrating pattern is shown with software with left and right.Certainly, calibrating pattern is only shown in view finder, and the view data of exporting from stereoscopic camera is only as photographed images data.

If the LCD monitor 101 by the 24th page of 21 row to the 27 page stereo tv camera that 4 row are illustrated 102 of this specification is carried out stereos copic viewing by stereopsis viewing glasses 103, can the relief adjustment state of visual confirmation.And, the stereopsis of watching with the monitor of this stereo tv camera, the photograph stereo broadcasting of transmission information of this stereo tv camera is carried out to information reception, can with beholder's perception with the third dimension of completely same state of watching stereoscopic TV.

Further, be no matter non-solid or three-dimensional situation, the in the situation that of photography dynamic menu, what side by side discover the state of affairs with photography is very important.Therefore it is huge, watching at ordinary times the action effect of television camera of the described structure of outdoor scene with monitor simultaneously.

If be very obvious by the 24th page of illustrated stereopsis camera head effect of 21 row to 27 page 13 row of this specification, but view finder portion (monitor) volume is large, in aspect existing problems such as hand-held photography or Portabilities.In addition, the shading of view finder portion is incomplete, so have the problem that is difficult to watch view finder picture in bright photography environment.

In Figure 12, on display, in the stereogram of the separated stereoscopic viewing device with glasses of field of excursion, keep display 121 plate 123 with glasses 130 separated with the visual field of stereoscopic viewing device 120 to be fixed with shell 123.Display 121 is for example LCD, in the image that left and right is used, at the wide W of illustrated picture _don P _lin part with left with image, at P _rin part, with right, with alternately timesharing demonstration of image, synchronize with glasses 130 with the visual field is separated, the visual field separation of left and right is carried out to stereos copic viewing.In the visual field, with shell 123, cover, outer light is by shading, so even under the bright environment outside room, observation display clearly still.In addition, display is fixed with visual field separation glasses relatively, so, even in the situation of observer's angled head, can noisy danger yet.

No matter the size of view finder (display), as explanation in Fig. 3, is large or little, according to the mode and the sighting distance that show, can carry out equal watching with standard size display frame, still, consider that the size of the display of tendentiousness occasion be take little of preferred.The occasion that display sizes is little, watches the distance of display less than the distance of distinct vision.The occasion that viewing distance is less than the distance of distinct vision, even face the people of (to the focusing of the bore hole distance of distinct vision), also need illustrated vision correction lens (positive diopter) in Figure 13, in addition, vision correction lens 133 moves to optical axis direction (not shown), thus, eyesight that can corresponding observer regulates.

Figure 13 is the separated pie graph with glasses 130 in the visual field of the stereo video apparatus 120 of above-mentioned Figure 12, and its main body forms with Polarizer 132 and liquid crystal board 131.The display 121 of the holographic display device 120 of Figure 12 is if LCD, display light is polarisation, the amplitude direction of relative display light, the Polarizer 132 as shown in by Figure 13 is configured in the orthogonal direction (left and right is simultaneously) that blocks above-mentioned polarized condition, and the visual field is closed.And if the place ahead of illustrated Polarizer 132 configuration liquid crystal board, the display light of LCD is spent by optically-active 90 or 270 degree, opens state in the visual field.Under this state, if liquid crystal board 131 is applied to voltage, the liquid crystal that reversed is nervous is linearity, and the optically-active not according to liquid crystal board 131 sees through with state so, therefore according to Polarizer 132 by shading, the visual field is closed.Synchronize the liquid crystal board 131 shown in Figure 13 is applied to voltage with the demonstration of the display 121 shown in Figure 12, thus, the visual field of separated left and right, carries out stereos copic viewing.In addition, in the above description, in the liquid crystal board 131 shown in Figure 13, execute alive occasion, the visual field is in closed condition, if but the direction of Polarizer 132 is equipped on equidirectional with the surperficial Polarizer of the display shown in Figure 12 (LCD) 121, on liquid crystal board 131, execute alive occasion, in the visual field, open state.

In addition, on display, use the occasion of the non-polarization elements such as organic EL, if used at the thinking further to append the so-called shutter glasses of another Polarizer above of the liquid crystal board 131 of Figure 13, can move comparably.In addition, when the discharge lamp that carries out bright light with commercial frequency is watched with shutter glasses, although can produce flicker, but in the view finder of Figure 12 120, outer light is interdicted, by the separated light of watching with glasses 130 in the visual field, be only the light of display, so, even the visual field is separated, with glasses 130 shutter glasses, can not produce flicker yet.

In addition, the view finder that is illustrated as stereo photographic device of 27 page of 14 row to 28 of this specification page 28 row, an embodiment for the holographic display device of claim 16, can be used as common holographic display device.In addition, the housing 123 of the holographic display device shown in Figure 12 120 can be situation beyond diagram.Such as being bellows or the common (not shown)s such as collapsible focusing hood of video camera in the past.

In the occasion of the holographic display device of placed type, display sizes is with larger being of a size of preferably to a certain degree.It is because generally, display more greatly more easily carries out high precision int.In the situation that watching large picture, if audience uses visual field separation glasses separately, have advantages of that many numbers can view and admire simultaneously, but, if under public's environment, consider the problem in health that other people glasses after using are used again, have advantages of that the mode that glasses watch is installed on display to be also difficult to give up.Under the occasion of this sample, also wish large display to a certain degree.And the position of placing display, that is, view and admire distance and wish in the distance of distinct vision with far.If in the distance of distinct vision with far, without the vision correction lens 133 shown in Figure 13, use audience normally used vision correction glasses or glasses are removed and watched separately itself, situation that can be same with the occasion of watching common object is corresponding, and distinguish also can (claim 17)

Electronic three-dimensional image shooting and display unit and by the juxtaposed stereoscopic photograph of two pictures, were in situation about developing on road separately in the past., due to the development of electronic type image (image) machine, although there are both to unify corresponding requirement, present situation is also not realize recently.The invention that the application's claim 18 is recorded is to requiring, for example, at a picture (a pair of picture in left and right) of the upper projection of electronic three-dimensional image display (stereoscopic TV), be made as the stereoscopic photograph printer of two picture juxtaposition formulas, in addition, can be from freely making the stereopticon of two picture juxtaposition formulas with the standard stereopsis data of digital three-dimensional video camera photography.

According to Fig. 1, in the juxtaposition indication range of illustrated left and right, if image about placing is separately watched, (distance of distinct vision has shortened sighting distance significantly relatively, so need vision correction lens), the visual field about the position of illustrated large-scale tv is consistent, just like exist large-scale tv to watch like that on illustrated display position.Fig. 3 is the details drawing of Fig. 1, the reference display D shown in Fig. 3 ₀the standard stereopsis data that represent are with juxtaposed left and right, left and right picture (illustrated D separately ₂and D (L) ₂(R) occasion) showing, display frame can diminish certainly, but is also common in the former non-stereopsis of the size of display frame size, and problem is how the picture interval of left and right determines and be not considered.

According to Fig. 3, the display D of standard size display frame ₀arrange distance as L ₀, by the juxtaposed three-dimensional printing machine of left and right image (slide projector) D ₂position (sighting distance) as L ₂, people's eye wide B if, picture interval (the illustrated D of the left and right of three-dimensional printing machine (slide projector) _p2) with D _p2=B (1-L ₂/ L ₀) decide.

Embodiment 2

The scheme of the present invention for stereoscopic TV broadcast is reproduced, moreover, also can upload stereopsis on the internet, the stereopsis of the commodity such as display communication sale, if or according to stereopsis, carry out the operating instruction of these commodity, can realize than showing the real better effect of commodity.This is because the commodity of reality have the situation of also not selling but needing to show, also exist the occasion of the limit more, thus the risk of remaining old product on sale even if space efficiency or most commodity are shown actual vendible commodity.If carry out the displaying based on stereopsis, the quantity of the commodity that actual StoreFront is shown can significantly be subdued.

Other, as selling use, it is also effective that the sale of automobile or furniture utilizes stereopsis.Being not only salesman the image after making video recording is watched to others, is also to have fabulous effect even sell at StoreFront.It is because automobile and furniture etc. need very large spacial flex, can not show a lot of commodity.In addition, the commodity of a plurality of great numbers are ready for to be illustrated in be also impossible economically, and, in real commodity, have in reality and use the one side that scene can not oblatio.This point, also identical in the sale such as dress material product, Fashion Show can be carried out to oblatio with stereopsis.

In addition, above-mentioned article are sold in example, even if large commodity also can carry out Mobile exhibiting, and the room in apartment or carry out in associated displaying with house, it is impossible that actual commodity are carried out to Mobile exhibiting.So occasion, has good effect.

More than associated application examples of selling, other, as sightseeing guide, using is also to have good effect.
