Description
The present invention relates to stereocamera, relate in particular to and have the stereocamera of regulating between the two phtographic lens optical axises (main shaft) apart from the mechanism of usefulness.
In phtographic lens being taken out simultaneously the stereocamera that two pictures use by right and the first from left, the distance between the optical axis of two phtographic lenses is normally fixed.Distance is in the fixing this stereocamera between optical axis, the position deviation of object body image on right and left two photographic pictures, to increase because of the parallax of this object distance convergence owing to two phtographic lenses, and in the stereoscopic photograph scope outside of right and left photographic picture, underlapped zone also increases.When film is contained on the anaglyphic lantern slide framework when by stereoscopic filmslide observation mirror it being appreciated, because underlapped zone can become dazzling thing, so use certain means, have polytype anaglyphic lantern slide framework of different view window width by preparation, and the framework of therefrom selecting to have suitable view window width comes the underlapped zone of right and left picture is covered.So well-known defective is, the loss of picture width is big, and picture masking amount under installation situation and lateral attitude determine be not easy.
Therefore, the present inventor has proposed the adjustable reflection-type stereocamera of distance between a kind of two phtographic lens optical axises, so that the result of collimation can pass through the view finder visual identification.In this stereocamera, distance between the two phtographic lens optical axises is adjusted to the identical mutually degree of collimating marks that makes the right side and left burnt plate (focal plate) go up same location position, to eliminate the underlapped part of right and left picture,, formation do not have the anaglyphic lantern slide of picture loss thereby having best stereoeffect.
The present inventor also once proposed a kind of reflection-type stereocamera of being made up of composite prism, the picture of the outside 1/2nd of wherein right and left camera lens camera coverage by symmetry reversed left to right and synthetic one just as, so that right picture and left picture can be observed by an eye, so that improve its legibility.In this stereocamera, also once proposed the overfocus governor motion and be used to regulate mechanism's interlocking of distance between two phtographic lens optical axises, so that automatically proofread and correct parallax according to photo distance.
Have the above-mentioned focal adjustments mechanism that is interlocked and automatically regulate the disembark stereocamera of structure of two optical axis spacings, owing to can automatically regulate between the optical axis distance with the range-independence of taking, so the loss of stereoscopic photograph scope can reduce, and snapshot is fabulous rapidly.Yet exist all objects in picture, to be configured in the situation of equidistance hardly, and the object of various distances usually is confused.Therefore, if at a distance main object is focused, the correction of distance between the optical axis of camera lens so becomes not enough with respect to in-plant object in the same picture.So when appreciating by stereoscopic filmslide observation mirror, in-plant object projects to this side that looks unusual from picture.For it is proofreaied and correct, perimeter right when mounted and left picture must suitably add covers.
On the other hand, in the stereocamera that has nothing to do with focal adjustments regulating distance between the optical axis, the cameraman can take a picture by proofreading and correct best parallax when observing viewfmder image, but the adjusting of distance between the adjusting of focus and the optical axis must separately be carried out.In this case, do not have obstacle when taking static material object or scene, but since fast when taking pictures performance can degenerate, so be unsuitable for snapshot.
As mentioned above, have the stereocamera of regulating the mechanism of distance between the optical axis, have merits and demerits according to photography target.Yet it is inconvenient picking up the stereocamera that carries two types, and its expense increases.
Therefore, in order to improve the problem of the convenience in the use, produce a following technical task that should solve: the automatic governor motion that promptly in a stereocamera, had both had distance between optical axis, can carry out distance between optical axes with manual mode as required again and regulate, so can distinguish the corresponding situation that requires the situation of photography fast and require parallax correction completely with a stereocamera.The objective of the invention is to solve above-mentioned problem.
In order to realize the foregoing invention purpose, the invention provides a kind of reflection-type stereocamera, it comprises: its structure is the incorporated camera body of two cover optical systems of single-lens reflex camera body; Two phtographic lenses; One is being parallel to interlock on the optical axis direction of camera lens to regulate the focal adjustments mechanism of focus by the pair of lens seat that will be contained on the above-mentioned phtographic lens; And mechanism that is used to regulate distance between the optical axis, so that the spacing of above-mentioned pair of lens seat is adjusted, be arranged on to camera lens translating cam left-right symmetric wherein the base that is used to support above-mentioned lens mount and above-mentioned focal adjustments mechanism, so that its cam face toward each other, on above-mentioned pair of lens seat, be provided with and the contacted mate of above-mentioned camera lens translating cam respectively; Above-mentioned pair of lens seat is promoted by spring along the direction that spacing increases, so that above-mentioned mate is advanced on the above-mentioned camera lens translating cam, to be configured to regulate automatically the mechanism of distance between the optical axis, the visual field of two phtographic lenses is always consistent aspect focal length about making, and with irrelevant to the feed of phtographic lens by above-mentioned camera lens translating cam; Be equipped with telescoping mechanism, be used for changing the spacing of pair of lens mobile device by means of feed screw and so on; Above-mentioned pair of lens seat is configured between the above-mentioned pair of lens mobile device, to constitute between the manual adjustments optical axis mechanism apart from usefulness.
The present invention further provides a kind of stereocamera, wherein form binocular view finder parts and single-lens view finder parts in removable mode, the former has the pair of right and left pentaprism, is installed in above the burnt plate of pair of right and left of above-mentioned stereocamera; The latter has composite prism, by a right left side, inboard 1/2nd picture symmetry ground on the burnt plate of pair of right and left is put upside down, with a synthetic erect image.

To be described in detail embodiments of the invention now.Fig. 1 represents camera body 2 and dismountable lens assembly 3 of stereocamera 1.The structure that this camera body has is that two cover single-lens reflex type video camera optical systems are according to the mechanism of the integrally provided optical system of parallel mode.Allow and upwards reflect the 45 reflective mirror 5R and the 5L of usefulness by the phtographic lens 4R of lens assembly 3 and the light of 4L incident, be installed in the left and right sides, the focal plane shutter (not shown) is configured in the back of reflective mirror 5R and 5L, can vertically turn round. Burnt plate 6R and 6L are installed in the top of reflective mirror 5R and 5L, treat that the view finder parts of describing later are installed in burnt plate 6R and above the 6L.
Referring to Fig. 2, box-like sliding seat 8 is assembled on the base 7 of lens assembly 3, and sliding before and after doing, and left and right sides lens mount 9R and 9L are installed in the front of sliding seat 8.When the focusing knob 10 on being installed in base 7 rotated, sliding seat 8 was by known feed mechanism (not shown) such as cam or rack and pinion mechanism and so on, and the optical axis that is parallel to phtographic lens 4R and 4L seesaws.Sliding seat 8 can by with base 7 on the guide rod engagement that forms, perhaps by guide rail is installed on the base 7, and is installed in the sliding seat 8 sleeve pipe with the engagement of guide rail sleeve pipe and is directed to.The vertical surface at base 7 rear portions and sliding seat 8 are associated in together by sliding expanding pipe structure or the bellows coupling that so forms, so that extraneous light can not leaked in the inner space of sliding seat 8 into.
Sliding seat 8 and lens mount 9R and 9L are associated in together by dove-tail form guiding mechanism 11 couplings, and lens mount 9R and 9L can slide on the direction perpendicular to optical axis.Move transmission shaft 12 along the camera lens on the upper surface that is installed in sliding seat 8 perpendicular to optical axis direction, formed 13 engagements of lens moving apparatus from center with its internal thread formation and dextrorotation and left-hand thread (LHT) with dextrorotation and left-hand thread (LHT) by symmetry ground.When camera lens moved camera lens on the transmission shaft 12 and moves knob 14 rotations, lens moving apparatus 13 was according to convergence or the separation mutually of sense of rotation symmetry ground.
Two lens mount 9R and above the 9L about helical compression spring 15 is configured in promote left and right sides lens mount 9R and 9L with the direction along expansion; And the cantilever 16 that provides at the upper surface of left and right sides lens mount 9R and 9L is towards the inboard of lens moving apparatus 13.
Tabular camera lens translating cam 17R and 17L by symmetry be installed in the front of base 7, the roller 18 that provides below with track in seat 9R and 9L is so that move by camera lens that the operation of knob 14 presses against camera lens translating cam 17R with roller 18 and above the 17L.In other words, when camera lens moves knob 14 along the rotation of direction that lens mount 9R and 9L are separated from each other, by helical compression spring 15 lens mount 9R and 9L are outwards moved, so that roller 18 promotes camera lens translating cam 17R and 17L, and further outwards motion of lens moving apparatus 13, to separate with cantilever on the 9L with lens mount 9R.
When camera lens moved knob 14 retrograde rotations, lens moving apparatus 13 ordered about lens mount 9R and 9L and moves along the direction of convergence each other from outer side compression cantilever 16, and roller 18 will divide with camera lens translating cam 17R and 17L and open.
Camera lens translating cam 17R and 17L so form, so that the camera coverage of right phtographic lens 4R and left phtographic lens is consistent aspect focal length, and irrelevant with the feed of this phtographic lens.Fig. 3 represents the mutual relationship between the distance between phtographic lens focus and optical axis.What allow it supposes use again is a thin lens, and:
The focal distance f of lens
Object is apart from the distance L of lens principal point
Lens focus to image spaces apart from if
So the if=f2/ here (L-f) sets up, therefore, the lens principal point becomes f+if to the distance on egative film surface.
In addition, if the spacing between the left and right sides exposed of stereocamera is P1, in order to make left and right sides camera coverage unanimity, the amount of movement S1 of left and right sides camera lens is provided by following formula so
S1＝(P1/2)(f+if)/(L+f+if)
In other words, along with object to the reducing of camera lens principal point distance, two camera lenses move an amount of movement S1 who is calculated by following formula along the direction of convergences mutually about can allowing.
The camera lens translating cam 17R and the 17L that represent among Fig. 2, the formation of its shape is based upon on the aforesaid equation basis, phtographic lens 4R and 4L are configured in the focal position of infinity by focusing knob 10, and camera lens moves 14 of knobs along the direction rotation that lens mount 9R and 9L are separated from each other.When roller 18 promotes camera lens translating cam 17R and 17L lens moving apparatus 13 is separated with cantilever 16, just become the state of distance between the automatic adjusting optical axis.
In this state, spacing between phtographic lens 4R and 4L optical axis is to change along the cam face of camera lens translating cam 17R and 17L, this translating cam 17R and 17L and the focal adjustments by focusing knob 10 lock together so that about the camera coverage of two phtographic lens 4R and 4L always consistent aspect focal length.The spacing of two pictures about being exposed, and the maximum spacing between two phtographic lens 4R and 4L optical axis are desirable for spacing 63.5mm between people's the eyes approximately.The fuselage 2 of video camera can changing-over lens assembly arbitrarily, have the lens assembly of various focal lengths by formation, by design, make the focal length unanimity of two phtographic lenses to camera lens translating cam 17R and 17L shape.
The single-lens view finder parts of describing when plan subsequently are mounted, and the departing from when regulating focus of 1/2nd images about in the observation view finder, under the state of regulating distance between optical axis automatically, need to regulate focus, but when lens moving apparatus 13 pushing cantilevers 16 so that roller 18 when separating with 17L, need to show and take the photograph the police with camera lens translating cam 17R; Under the state of distance between the manual adjustments optical axis, microswitch 19 is installed in the outside of the movable range of sliding seat 8 upper surface places one cantilever 16.Even when lens moving apparatus 13 moves to when focusing on infinity also not with external position that cantilever 16 contacts, just push the button of microswitch 19, detect with state to distance between the automatic adjusting optical axis.
The electrode of microswitch 19 links to each other with contact (not shown) on base 7 rear surfaces through lead 20.Referring to Fig. 1,, be configured in the center of camera body 2 front surfaces with corresponding contact 21, the contact on the lens assembly 3.When being installed in lens assembly 3 on the camera body 2, microswitch 19 just links to each other with controller on the camera body 2.The photometric measurement contact 22 that links to each other with the photometric measurement element of view finder parts, detect contact 23 in order to the view finder of discerning the view finder kind of describing subsequently, and, be configured near camera body 2 part of the body cavity above the diaphragm housing the heart and lungs plate 6R and the 6L inner edge in order to the light-emitting component 24 of display alarm.
Referring to Fig. 4, the figure shows the stereocamera 1 of the binocular view finder parts 31 that one of two types of view finders are installed.These binocular view finder parts 31 have pentaprism 33R and 33L, and are corresponding with burnt plate 6R and 6L in the camera body 2, are assembled in the single big envelope 32.34 of photometric measurement elements are assembled in the pentaprism 33.The contact 35 of photometric measurement element 34 contacts with photometric measurement contact 22 on the camera body 2.By the speed of controller control shutter or the auto iris of phtographic lens, perhaps both control simultaneously, provide suitable exposure for film, to constitute known automatic exposure mechanism.
In binocular view finder parts 31, do not provide with camera body 2 on view finder detect 23 corresponding contacts, contact.When binocular view finder parts 31 were mounted, view finder detected the state of contact 23 and opens a way.
Be incident on the light on phtographic lens 4R and the 4L, will be by reflective mirror 5R and 5L in burnt plate 6R and imaging above the 6L, and burnt plate 6R and above the 6L by pentaprism 33R and 33L by the image erect image that flips out reversed left to right, can by about two eyepiece EP observe.Referring to Fig. 1, burnt plate 6R and indicate with collimating marks MR and ML above the 6L that the heart and the left and right sides have the circular pattern in three vertical curves and centre therein.When the focus of phtographic lens 4L and 4R is focused at infinity, this phtographic lens 4L and 4R aim at infinity under the state of regulating distance between the optical axis automatically, by outwards motion and separating of above-mentioned lens moving apparatus 13 with cantilever 16, and about two viewfmder image observed by two and examine, about collimating marks MR and ML on burnt plate 6R and the 6L, be observed to unanimity, shown in Fig. 5 (a).
When focusing knob 10 rotation when transmitting phtographic lens 4R and 4L, phtographic lens 4R and 4L will move on the direction of convergence mutually along camera lens translating cam 17R and 17L so that about two camera coverages consistent automatically and irrelevant with photo distance.Therefore, the parallax of phtographic lens 4R and 4L for subject from normal moveout correction, and irrelevant with photo distance so that the locational object of focusing is being shot on same position in the picture of the left and right sides.So, under situation about egative film being installed on the anaglyphic lantern slide framework, need hardly to come parallax is proofreaied and correct by regulating the egative film spacing.Owing to prepare in the picture of the left and right sides to be reduced, can form the little anaglyphic lantern slide of picture loss by the underlapped part of the view window of slide mount shielding.
Yet, if some objects in the picture are present in different distances, so when focus is focused a long way off object, relative position between the object that close-ups arrives and collimating marks MR and ML, about be different on two burnt plate 6R and the 6L, therefore about two collimating marks MR and ML inconsistent, but according to collimation to close-ups object eyer, be seen as two, shown in Fig. 5 (b).In this case, when camera lens move knob 14 rotation with shorten between phtographic lens 4R and the 4L optical axis apart from the time, as shown in Figure 6, the object IR and the IL of close-ups, about will move along the direction of convergence each other on two burnt plate 6R and the 6L; And in the positive view finder by pentaprism 33R and 33L mistake reversed left to right resembled, the object IR and the IL of close-ups will be along the image reverse movements on direction separated from one another and the burnt plate.The parallax that burnt plate 6R and 6L go up collimating marks MR and ML will be corrected, shown in Fig. 5 (a), it reached that collimating marks MR and ML meet a bit, and the visual field of phtographic lens 4R and 4L is almost consistent on the distance of close-ups object.
Under the situation of distance between the manual adjustments optical axis, naked eyes look to be thought, object is with respect to the front and back position of collimating marks MR and ML, along with camera lens on making burnt plate 6R and 6L collimating marks MR and the amount of movement in the moving range that meets of ML change.Good especially stereoeffect, be collimating marks MR consistent with ML and with the irrelevant camera lens moving range of amount of movement in obtain, but except the object of planning to be observed nearby from picture jumps back out to the situation of special-effect of this side, if like this adjusting of carrying out make by meet together collimating marks MR and the distant place of ML observe whole object, then the stereo-picture of close-ups object does not focus on closely and locates under situation about being appreciated by light body filmslide observation mirror, but can obtain the anaglyphic lantern slide of nature stereoeffect.
When the above-mentioned anaglyphic lantern slide of being produced is installed in the anaglyphic lantern slide framework, to about object in two pictures under best situation, carried out parallax correction, thereby do not need to cover underlapped part, be provided with the anaglyphic lantern slide framework that almost resembles real screen size view window of a size but can use, so the picture loss can be eliminated.
When this lantern slide is installed on the anaglyphic lantern slide framework, if this lantern slide is installed in about view window about two centers and lantern slide on the reference position that two centers are consistent, the stereoeffect of confirming by view finder in the time of then can obtaining to photograph, and need be along with the photo distance of object is adjusted the installation site of lantern slide.
Referring to Fig. 7, represented is the stereocamera 1 that single-lens view finder parts 41 are housed.Being assembled in the composite prism 43 in the single big envelope 42, is in the camera coverage of two camera lenses about stereocamera, and symmetry ground proposes for the present inventor by the prism of using with a synthetic erect image reversed left to right of outside 1/2nd pictures.
Single-lens view finder parts 41 have photometric measurement element 44 in its composite prism 43 1 sides, and have with camera body 2 on the contact 45 of contact 22 contacted photometric measurement elements 44.Be further provided with view finder above the camera body 2 and detect 23 contacted contacts 46, contact.
Referring to Fig. 9, the spacing P2 in the composite prism 43 between the summit of 180 ° of reflecting prism unit 47R and 47L, be about half of spacing P1 between the exposure picture center, and its overall width W conversation structure spacing P1 is wideer slightly.
Referring to Fig. 8, composite prism 43 is such, so that about the plane of incidence of two 90 ° of total reflection prism unit 48R and 48L be installed in about one of two lump coke plates, inboard half territory towards burnt plate 6R and 6L, so that by lower one to being incident on light on 90 ° of reflecting prism unit 48R and the 48L by three total reflections, and along continuous straight runs is gone out from projection flat board 49.
Through after camera lens 4R and the 4L up and down and reversed left to right resembling, be upside down by reflective mirror 5R and 5L, and erect image reversed left to right just is formed on burnt plate 6R and above the 6L.About two lump coke plate 6R and 6L to go up the picture of inboard two/part reversed left to right by symmetry ground, good about outside half part of camera coverage of two camera lens 4R and 4L, reversed left to right by prism 43 by symmetry ground.Therefore, in the left camera lens 4L camera coverage outside half part just as, be projected to half part of the left side of projection flat board 49 in the prism 43; And in the right camera lens 4R camera coverage outside half part just as, be projected to half part of the right of projection flat board 49, thus synthetic picture. Burnt plate 6R and 6L do not need to have the size same as picture, but can have the size that equals or be slightly larger than this prism plane of incidence, and the size of prism is then near half of picture dimension.
Figure 10 represents another embodiment of composite prism in the single-lens view finder parts.Opposite with prism 43 known among Fig. 7, half part of inside of the projection plane of 180 ° of reflecting prism unit 53R and 53L that this composite prism 51 has is connected on the right side one half-sum the first from left half part of 90 ° of reflecting prism unit 52 at center.Identical with the prism of representing among Fig. 7 43, light is by three total reflections.Spacing between 180 ° of reflecting prism unit 53R and the 53L summit and total width, same measure-alike with prism 43.
When above-mentioned single-lens view finder parts 41 are mounted, lens assembly 3 is set under the state of distance between the automatic adjusting optical axis, therefore, except the focal adjustments situation is by the situation of the picture on burnt plate 6R and the 6L by naked eyes identification, and focal adjustments in addition outside situation about can carry out at an easy rate under the dark photography environment focal adjustments situation can by horizontal two/a part of view finder picture departing from determine.
Referring to Figure 11 (a), represented is subject; Referring to Figure 11 (b), 11 (c) and 11 (d), the view finder of represented is single-lens view finder 41 resembles.When the object of the rotation of stereocamera along continuous straight runs and Figure 11 (a) expression was configured in the picture center, if object is focused, the object of two camera lens visual field intersections was in sight with the true shape shown in Figure 11 (b) about then being configured in.
When this object was configured in away from the distance of focal position when last, promptly be in away from about the distance that crosses of two camera lens visual fields last, then object looks shown in Figure 11 (c); And when this object is configured in when farther, this object is observed to the echo that left and right sides separates.On the other hand, when this object be configured near about during two camera lens visual field intersections, become the core at dead angle to be covered, and be seen as the narrow width shown in Figure 11 (d).In this manner, focusing knob 10 so rotates, so that the object in the view finder picture is in sight with true shape, thereby picture is focused.
In addition, decide with object, parallax might be difficult for proofreading and correct, and focus might be difficult for regulating.Particularly, when object is a perpendicular line or horizontal line, may just be difficult to determine the state and the parallax of focusing.In this case, stereocamera should not be to be exactly to the right that square neck is oblique left from horizontality, so that easily understand the state of focal adjustments.
When two camera lens 4R about stereocamera 1 and 4L focusing during at infinity, its optical axis just be configured in be exposed about the center of two pictures.When single-lens view finder unit 41 is mounted, by about the synthetic view finder picture of the outside one half field-of-view of two camera lens 4R and 4L just in sight, therefore, width equal spacing between camera lens 4R and 4L optical axis towards about the center at two camera coverage centers beyond the visual field.Yet the invisible zone of eyes is very narrow rectangular part, and does not almost have object to hide in this zone.When the deflection of stereocamera along continuous straight runs, the whole object in all camera coverages can both be seen, does not therefore have inconvenience in shooting picture.
When single-lens view finder parts 41 are installed between automatic adjusting optical axis when preparing photography down apart from state, parallax locks together from normal moveout correction and focus adjustment, thus about have underlapped part hardly in two pictures; But be focused when remote object, and when under the state of the parallax correction deficiency of the object of close-ups, photographing, must when similar conventional stereo video camera is installed, proofread and correct parallax by covering the film outside, the left and right sides.Yet with do not compare with regulating the disembark common stereocamera of structure of optical axis spacing, about the area of the underlapped part of two pictures will reduce significantly, thereby can obtain the very little anaglyphic lantern slide of picture loss.
When being used for by the departing from the single-lens view finder parts 41 of regulating focus and be mounted of horizontal half picture elephant of finding a view, if phtographic lens 4R and 4L distance between optical axes are manually proofreaied and correct, if being the parallax by two pictures about changing, same even focal position obtains, so laterally departing from of half elephant will change, and it is impossible that the focal adjustments that image departs from is become, thereby the duty of distance between the automatic adjusting optical axis need be set.Therefore, if become the duty of distance between the manual adjustments optical axis mistakenly, then when single-lens view finder parts 41 are installed, need by any means display alarm.
Referring to Figure 12, represented is the alarm indication embodiment of circuit.When single-lens view finder parts 41 are installed on the stereocamera fuselage 2, its contact 46 just with camera body 2 on the view finder parts detect contact 23 and contact.Microswitch 19 on the above-mentioned lens assembly 3 is normally closed, when single-lens view finder parts 41 are installed between the manual adjustments optical axis under the state of distance, promptly will be used for the emitter of the transistor Q1 of driving LED 24 light-emitting components under the ON state that the button of this microswitch 19 is not pressed, link to each other with (-) power supply by the fuselage touchdown line.Therefore the alarm indication circuit is energized, and free-running multivibrator 25 is activated, and transistor Q1 is driven, the LED24 predetermined time interval that glistens so that between warning manual adjustments optical axis apart from the user of state.
On the other hand, referring to Fig. 4, owing to do not provide on the binocular view finder parts 31 with view finder and detect corresponding contact, contact 23, so how LED24 is not luminous no matter regulate the state of distance between optical axis when binocular view finder 31 is installed, and automatic and manual state can be changed arbitrarily and photographs.Certainly, under view finder parts 31 and 41 all were not installed in state on the camera body 2, LED24 was not luminous yet.
The present invention never is confined to more above-mentioned embodiment, but change in every way in technical scope of the present invention, should be pointed out that the present invention comprises the example that these have changed certainly.
For the stereocamera of the present invention of above detailed description, provide and automatic adjusting camera lens optical axis that focal adjustments locks together between apart from the mechanism of usefulness, and can carry out the manual adjustments of distance between the optical axis.Therefore, when using the mechanism that regulates distance between the optical axis automatically, about the camera coverage at the focal length place of two camera lenses only make its unanimity by focus adjustment, be corrected to suitable situation by the horizontal parallax of the object on the focussing distance, so can be about having suppressed the underlapped part of two pictures, promptly suppressed to photograph under the state of the picture loss in the stereoscopic photograph.
When having distant objects and in-plant object simultaneously, regulate distance between the optical axis with manual mode, in the effect of using the parallax correction that the distance adjusting obtains between confirming by optical axis of binocular view finder parts, can under the correcting state of the best, photograph.Therefore,, can easily take high-quality stereoscopic photograph, so the present invention can make contributions to the universal of stereoscopic photograph by using above function respectively according to different situations.
