Description
The present invention relates to stereo slide mount, more particularly, relate to and to cover the stereo slide mount that image plane provides accurate stereoscopic image by the part.
In image is taken the photograph thereon anaglyphic lantern slide by the stereoscopic camera that has the structure of fixed interval (FI) between the optic axis of left and right sides camera lens, because the visual field difference between the phtographic lens of the left and right sides, non-overlapped part is stayed the left-hand component of left image plane and the right-hand component of right image plane according to target range.
For observing with the stereopticon sight glass, because lack stereoscopic image, those non-overlapped parts have been interdicted sight line.In order to eliminate this blocking, normally used method be image plane hole width by making stereo slide mount less than an image plane width of anaglyphic lantern slide, cover the non-overlapped part of left and right sides image plane.
The width of the non-overlapped part of covering becomes big with object distance, when about the coupling of image when not enough, this has a strong impact on generation (though according to size, position, color, contrast etc. and different).Therefore, lantern slide is by the stereo slide mount that has the hole width that changes by the step from many kinds, selects to have suitable image plane for each anaglyphic lantern slide and covers the stereo slide mount of scope and install.So because cover image plane, image is taken the photograph the loss that thereon lantern slide can not be avoided image plane by optic axis gap fixed stereoscopic camera, and this lantern slide comprises the flaw that loss increases in the image plane when close-up photography.
On the other hand, the stereoscopic camera that is equipped with the mechanism in gap between the optic axis of regulating left and right sides camera lens can be regulated the visual field of left and right sides camera lens, and therefore, it can proofread and correct parallax according to object distance.So, needn't cover the outer edge portion of left and right sides image plane in theory with slide mount, therefore,, just can obtain suitable stereoeffect if the lantern slide unification is placed on the stereo slide mount in the hole with the image plane width that equals lantern slide.Yet, in the following cases, though image by automated optical between centers crack adjustment type or manually optic axis gap adjustment type stereoscopic camera take the photograph thereon lantern slide, also need by covering the ratio that left and right sides image plane comes corrected perspective figure each several part.
Such as, when to about the coupling of image have the object that has a strong impact on when the distance that is shorter than master object is taken, must cover the outer edge portion of left and right sides image plane, with the ratio of corrected perspective figure each several part.
When shooting is under the ratio overcorrect state of the skeleton view each several part that causes owing to the optic axis gap in the mistuning type hand optic axis gap adjustment type stereoscopic camera (for too short optic axis gap) when carrying out, the ratio of necessary corrected perspective figure each several part, opposite with above-mentioned situation, be by covering the internal edge part of left and right sides image plane.
Yet, be under the state of having proofreaied and correct parallax on certain program, to carry out because take, so the anaglyphic lantern slide that image is taken the photograph thereon by optic axis gap adjustment type stereoscopic camera need have the minimum leeway of covering.Therefore, suitable method is the hole by the stereo slide mount that is biased to the hole width with the image plane width that is slightly less than lantern slide of regulating lantern slide, covers the part of image plane.
Yet in the stereo slide mount of prior art, when regulating the position of lantern slide with respect to the frame hole, lantern slide is located by being bonded on the underframe.Therefore, positioning action is very difficult, and out of true is pretty troublesome, does not have efficient.
Therefore, the objective of the invention is to solve the technical matters for providing stereo slide mount to solve, this stereo slide mount is easy to fitting operation, and positioning action is accurate.
According to the present invention, as what advised in order to achieve the above object, be provided at perforation and its each take about paired and have stereo slide mount identical relative position, that be used for the anaglyphic lantern slide that image mounted thereto taken by stereoscopic camera between the image plane, this stereo slide mount comprises:
Underframe and cover frame respectively have two square holes arranged side by side each other, and underframe has the angle of the perforation that is used for cooperating the lantern slide that will fix at its lantern slide installed surface, to place two lantern slides; Cover frame has pin hole corresponding to angle at its lantern slide clamping face, so that underframe and cover frame fit by angle being buckled into the pin hole,
Wherein, the slide mount system is made of many kinds stereo slide mount that hole, the left and right sides has equidistant from distance and an equal wide in it, the wide image plane width that is slightly less than lantern slide of its mesopore, and wherein the spacing in the angle of the angle of left lantern slide and pin hole and right lantern slide and pin hole is different by the step, so the difference of the lantern slide installing space that the biasing of left and right sides lantern slide can be by each stereo slide mount is regulated.

The present invention will be with reference to the accompanying drawings, be described in detail as follows in conjunction with embodiment.Fig. 1 represents the #A stereo slide mount 1 of the zero lantern slide biasing in the stereopticon frame system.Comprise the underframe of making by the injection molding resin 2 on this stereo slide mount 1 structure, and be stacked in the cover frame 3 on the underframe 2.This underframe 2 is equipped with identical profile with cover frame 3, and respectively has a pair of left and right sides hole 4L and 4R, 5L and 5R in same position.
As shown in Figure 2, underframe 2 has on four jiaos of the independences of hole, left and right sides 4L and 4R and stretches out so that column angle 6L and the 6R that cooperates with the perforation of lantern slide.As shown in Figure 3, cover frame 3 has pin hole 7L and the 7R that the position aligns with the angle 6L and the 6R of underframe 2.On the other hand, underframe 2 has perpendicular grooves 8 at its center, back, and therefore, it can rely on the turning joint doubling of perpendicular grooves 8.
Fig. 4 represent by nine kinds of stereo slide mounts 1 that on the side surface direction of lantern slide, have the different biasing of step-length (#-E,---, #A,----, and #E) the stereopticon frame system that constitutes.Though Fig. 4 represents three kinds (#-E, #A and #E) among nine kinds of stereo slide mounts 1, the step number of frame is not limited to this.
Each #-E reaches 5L and 5R and has fixed width W to the hole 4L and the 4R of the image plane of the stereo slide mount 1 of #E, and this width W is made as the W=31 millimeter, slightly is narrower than 32 millimeters image plane width of lantern slide.Left and right sides image plane hole 4L and 4R, and 5L and 5R have constant spacing PW, but the spacing PP between near the left lantern slide angle 6L four jiaos at the image plane window and pin hole 7L and right lantern slide angle 6R and pin hole 7R number is unit increase/minimizing with 0.125 millimeter for each frame.Here, consider to utilize the observability of stereopticon sight glass, the spacing PW in hole, the left and right sides need be made as 63.5 millimeters of standard values, or a little less than two of people's spacing.
In #A stereo slide mount 1, shown in Fig. 4 (b), the spacing PW of the installing space of lantern slide and image plane hole 4L and 4R and 5L and 5R equates, therefore lantern slide is biased to zero, and the outer end portion of the image plane of lantern slide and inner end portion are respectively covered 0.5 millimeter by image plane hole 4L and 4R and 5L and 5R.And lantern slide outwards is biased in forward according to #B with respect to image plane hole 4L and 4R and 5L and 5R's,---and the order of #E increase, so the outer end portion of the image plane of lantern slide is covered 1 millimeter at the #E place.On the other hand, lantern slide is docile and obedient preface #-B with respect to image plane hole 4L and 4R and 5L and 5R,---and #-E in partially.At the #-E place, lantern slide is with respect in image plane hole 4L and 4R and 5L and the 5R inclined to one side 1 millimeter, so the inner of the image plane of lantern slide is covered 1 millimeter.
Here, the stereo slide mount of negative sign (#-B,---, and #-E) be the lantern slide of under the situation of the stereoscopic camera exaggerated correction parallax that has type hand optics axle base adjusting mechanism because of faulty operation, taking with thereon image.Usually, parallax is proofreaied and correct by the scope of covering of adjusting the outer end portion of image plane with #A to #E stereo slide mount.
In the time will stereopticon being installed, the scope of covering of lantern slide is covered scope and is determined that device selects to have the stereo slide mount of biasing of the scope of covering of coupling and determine by following scope guiding device or another covered.Then, lantern slide is installed in hole, the left and right sides 4L and 4R of underframe 2 of selected stereo slide mount, and cover frame 3 and underframe 2 are by being placed on cover frame 3 on the underframe 2 and with angle 6L with 6R buckles into pin hole 7L and 7R fits.
Because underframe 2 can doubling on the part of perpendicular grooves 8, so a left side half or the right side partly all can buckle into earlier, so that angle 6L and 6R and pin hole 7L and 7R are located at an easy rate, so the efficient of installment work is very satisfied.On the other hand, because groove is not rolled on the surface of cover frame 3, and shape is flat, so convenient at cover frame 3 submit a written statement to a higher authority headline or photograph record.Perhaps, can fall in, so that write title and so on or label is sticked on recess at recess at hole, the left and right sides 5L of cover frame 3 and the gap between the 5R.
If lantern slide has the ellipse perforation of circular perforations or lateral elongation, then, only utilize column angle 6L and 6R accurately to keep its side and upright position here by suitably setting the diameter of angle 6L and 6R.If lantern slide has the vertical elongated perforation as 135 films, then the upright position can roughly be depended on diameter or the shape of angle 6L and 6R roughly.
The embodiment that the degree of accuracy of the perpendicular positioning of Fig. 5 and 6 expression lantern slides is improved.As (a) among Fig. 5 with (b), underframe 2 also has the angle 11L and the 11R of the vertical direction that is used to adjust lantern slide except the angle 6L and 6R of the lateral position that is used to adjust lantern slide.As (c) among Fig. 5 with (d), cover frame 3 has pin hole 7L and 7R and 12L and the 12R that is buckled on angle 6L and 6R and 11L and the 11R.
On the other hand, as shown in Figure 6, underframe 2 has the lateral groove 13 that width equals the vertical length of lantern slide at its vertical center section, therefore as shown in Figure 5, and by lantern slide being put into the upright position that groove 13 is adjusted lantern slide.
When lantern slide will be installed on the stereo slide mount 1 of the present invention, the suitable image plane of a pair of stereophotograph on the magic lantern slip is covered scope and is determined by covering the scope guiding device, and lantern slide to resemble with a frame be to be installed in unit blocks on the stereo slide mount that has with the biasing of determining of covering commensurate in scope.Then, paired left and right sides magic lantern can be located by angle 6L and 6R, and the part of left and right sides image plane can be covered so that accurate stereoeffect is provided.
Fig. 7 represents to be suitable for to select the embodiment of the scope of the covering guiding device of stereo slide mount 1.Shown in cover scope guiding device 21 and structurally constitute by the following method: the frame 22 with two left and right sides optical systems that comprise projection lens 23L and 23R, focusing glass 24L and 24R and eyepiece 25L and 25R is provided, and lantern slide guide rail 26 is fixed on rear portion (as be positioned at Fig. 7 top), make that the magic lantern slip F that is contained in the lantern slide guide rail 26 can be in sight.
The lens board 27 that projection lens 23L and 23R be installed on it is fixed on the center section between the front and back of frame 22.Be positioned at frame 22 the front portion, and prop feed screw 28 from the side, the arm 30L and the 30R that are installed on left and right sides focusing glass support 29L and the 29R be carved with internal thread (although not shown), so that hold feed screw 28 by spherical screw mechanism.
Feed screw 28 is divided into reference side to threading clockwise and widdershins symmetrically with the intermediate portion, make the spacing between focusing glass 24L and the 24R to regulate at the knob 31 of the afterbody of feed screw 28 by turning clockwise, so that left and right sides focusing glass support 29L and 29R are close to each other on the direction perpendicular to optic axis, and make left and right sides focusing glass support 29L and 29R separated from one another by being rotated counterclockwise knob 31.
Fig. 8 represents left and right sides focusing glass 24L and 24R, and they do equally so that with protective materials frame FL cover graphics planar peripheral, perhaps cover described part but not image plane by the image plane periphery being painted black.The image plane width of focusing glass 24L and 24R is made as the image plane hole width γ of 31 * projection magnification ratio of stereo slide mount (#-E to #E), for example, for the γ of projection magnification ratio=1 o'clock, is made as focusing width=31 * 1=31 millimeter.On the image plane of focusing glass 24L and 24R, form left and right sides collimation pattern CP identical, that mainly constitute by printing or engraving mode, the side direction of improving projection image plane, the left and right sides thus visibility that the coupling that caused changes that relatively moves by many vertical bars.
In Fig. 7, although not shown, be positioned at forefront and slide in the face of the eyepiece support frame 32L of focusing glass 24L and 24R and 32R are furnished with well-known manually side direction symmetry, to regulate the flexible link gear that width between eyepiece arrives two spacings of user.And, be similar to the ordinary optical device, can regulate diopter by barrel 32La before rotating and 32Ra.
By at the fixing semicircle reflecting plate 33 of the rear end tails of lantern slide 22, and will take lamp 34 and be installed in, constitute a kind of diffused light source, to illuminate the back of lantern slide guide rail 26 equably by in the definite inner space of reflecting plate 33 and lantern slide guide rail 26.
Lantern slide guide rail 26 has left and right sides image plane hole 26L and the 26R that possesses corresponding to vertical and the lateral dimensions and the spacing of the image plane form of stereoscopic camera, therefore, the image plane of a pair of stereophotograph of magic lantern slip F can be to the exposure of the inside of image plane hole 26L and 26R.
When magic lantern slip F will be installed on the lantern slide guide rail 26, like this lantern slide guide rail 26 is inserted at its emulsion face sensing rear portion (towards light source), so that the left image plane of paired stereophotograph is positioned at the left image plane hole 26L of lantern slide guide rail 26, and right image plane is positioned at right image plane hole 26R.As see from the front portion on the image plane hole 26L of lantern slide guide rail 26 and the vertical/horizontal reverse image plane in the 26R by projection lens 23L and 23R focus on become on focusing glass 24L and the 24R just as, making should be just as seeing by left and right sides eyepiece 25L and 25R.
Post letter at the afterbody of feed screw 28 and knob 31 coaxial mounted index dials 35, make on the straight line of principal point of the center that is centered close to the image plane that is connected lantern slide F of focusing glass 24L and 24R and projection lens 23L and 23R corresponding to each frame number (#-E to #E) of stereopticon frame system.
When index dial 35 on "+" direction from #A to #B,--in-and #E when rotation, left and right sides focusing glass 24L and 24R be at direction upper offset respect to one another, so the frame FL that the perimeter on projection image plane is focused screen 24L and 24R covers.And when mark #E was consistent with pointer M, each inwardly setovered focusing glass 24L and 24R 0.5 millimeter.
On the other hand, when index dial 35 on "-" direction from #-A to #-B,--in-and #-E when rotation, left and right sides focusing glass 24L and 24R move away from each other, so the frame FL that the interior zone on projection image plane is focused screen 24L and 24R covers.When mark #-E is consistent with pointer M, each outer inclined to one side 0.5 millimeter of focusing glass 24L and 24R.
And, in the aforesaid operations index dial, change with the variation of covering scope with respect to the ratio of the skeleton view each several part of collimation pattern CP.So index dial 35 rotates when observing stereoscopic image, make stereoscopic image flush with the collimation pattern or deeply can see in the plane of (deep).If when observing in this state by the sequence number of the index dial of fixed pointers M indication, the observer can find the sequence number that can set up for the stereo slide mount of the parallax correction state of stereophotograph the best (#-E,---, and #E).
As mentioned above, if lantern slide is installed by selecting to have the stereo slide mount of covering the lantern slide biasing that scope guiding device and so on determines by image plane, stereo slide mount of the present invention can be proofreaied and correct the accurate parallax of object, to see high-quality stereoscopic image.Even the lantern slide biasing is according to each frame difference, all left and right sides image plane spacings equate.Even when many stereo slide mounts with the biasing of different lantern slides were often changed, the optical angle of the sight line of right and left eyes was fixed, to provide the eye fatigue degree very little effect therefore.
Here, the present invention should not be limited to above embodiment, but can revise in many ways in its technical scope, so the present invention has also comprised these remodeling certainly.
