Description

  The present invention relates to a stereo slide mount, and more particularly to a stereo slide mount that records left and right images side by side on a single sheet or film using electronic stereoscopic video data.

  Recently, with the development of digital technology, digitization has progressed in the video field at all stages from shooting to display. Even in stereo photography (a pair of left and right transparent images or opaque images juxtaposed on a single sheet), it has been proposed to print a stereo photograph using electronic video data (for example, the feature of Patent Document 1). No. 2002-125245).

  Similarly to Patent Document 1, the captured stereoscopic video data is temporarily displayed on a personal computer screen with a pair of left and right screens juxtaposed, trimmed, and then printed in a predetermined two screens. The thing is proposed (for example, Unexamined-Japanese-Patent No. 2004-129186 of patent document 2).

  The methods described in Patent Documents 1 and 2 adjust and print stereoscopic video data after shooting in a post process (editing stage). Recently, image data captured by a stereo camera is personalized. A technique has been proposed in which anyone can easily enjoy stereoscopic viewing simply by displaying on a computer display or printing it out (for example, paragraph of Japanese Patent Laid-Open No. 2006-121229). [0013] [0041]}.

  In the case of a stereophotograph, in the case of a transparent slide, the left and right films are mounted and held by a stereo slide mount. {For example, US Pat. No. 4,942,684 of Patent Document 4 ('90, (July patent)} printed on photographic paper or the like is often affixed to a board having a certain thickness or is sandwiched with a holder or the like in the same way as a transparent slide.

  Further, a general stereo slide is configured so that left and right films are attached separately, but a stereo slide in which an integral film in which left and right images are recorded side by side is mounted has also been proposed (for example, Patent Document 5). No. 60-501079).

  According to the description of paragraph [0015] [Means for Solving the Problems] of Patent Document 1, the “stereoscopic image” of Patent Document 1 is one in which left and right screens are arranged at opposite positions (cross-view method), Although a large screen print can be viewed, a special method must be used to enable anyone to easily view stereoscopically (for example, the method shown in FIG. 13 of Patent Document 1). This method uses a polarizing plate for both the three-dimensional print and the glasses, so not only the field of view becomes very dark, but if a prism is used for the glasses as shown in the figure, the contour of the image is changed due to the difference in refractive index depending on the wavelength of transmitted light. There are problems such as color bleeding.

  Further, as shown in FIG. 13 of Patent Document 1, the stereoscopic vision by the cross-view method can stereoscopically view a large screen, but is illustrated by a broken line in the stereoscopic vision although the large screen is viewed. There are drawbacks that make it look very small.

  Patent Document 2 describes an editing method for performing two-screen side-by-side stereoscopic printing from electronic stereoscopic image data. However, since this method also displays a pair of left and right small screens on the screen of a personal computer (PC) and adjusts them under autostereoscopic viewing, editing work during printing is extremely difficult. Patent Document 2 also describes a three-dimensional monitor based on an anaglyph system for displaying red and blue, but while previewing a three-dimensional image of an anaglyph display (left and right screens are displayed in the same position), Determining the trimming range of the juxtaposed display type stereoscopic image makes it difficult to put it into practical use. This is because the trimming of a stereoscopic image is not just a pictorial composition determination, but as a means of perspective adjustment. When an image for right and left is displayed in the same position as an anaglyph This is because the stereoscopic effect and the apparent screen size differ between the case where the left and right images are displayed side by side. However, Patent Document 2 does not consider this problem.

  Japanese Patent Application Laid-Open No. 2004-228561 describes the content of stereoscopically printing out image data from a stereo camera. According to the description, the left and right image adjustment method is performed by adjusting the overlap area with parameters stored in advance, and this overlap area seems to be uniquely determined by the baseline length and zoom magnification. .

  However, in practice, when the overlap area described in Patent Document 3 is uniquely determined by the base line length and the zoom magnification (that is, even if it is a stereoscopic image in which only the overlap area portion is printed by trimming adjustment) ) Expected to not function effectively. This is because the close-range image and the infinite image are simultaneously shown in FIGS. 5 and 6 of Patent Document 3, but in such a case, even if the image of the non-overlapping portion is shielded (cut), it is observed. This is because the user's line of sight is matched toward an image at a close distance, and the left and right image frames appear to be shifted in some cases even when stereoscopically viewing a pair of images in the overlap area.

Further, paragraph [0043] of Patent Document 3 describes that “... the base line length is preferably about 10% of the distance to the subject”. In this case, if the human distance between the pupils is 65 mm, the subject distance is 65/0, 1 = 650 mm. Usually, from the limit value of 2 meters at which the person can see the infinity and the foreground at the same time. It is inevitable that even if only the overlap area is selected, it becomes inevitable that the distant view image and the near view image in the overlap area can be merged.

  Further, when a conventional silver salt film is used, it has an “entity” called a film. Therefore, a contractor who has requested development or other processing needs to attach a label with the client's ID on the actual product, but since there is no “entity” in the image of electronic data, many images are printed on the film. -After development, there arises a problem that it becomes difficult to distinguish who has requested each photo.

  The stereo slide mount described in Patent Document 4 locks the perforation of the film with an adjustment pin that is slid onto the mount, and is the only commercially available mount that uses the perforation of the film. belongs to. However, the problem that it is difficult to find the optimal adjustment position has not been solved.

  In the stereo slide described in Patent Document 5, a left and right integrated film in which left and right images are recorded side by side is locked by pins provided on a mount. However, the stereo slide of Patent Document 5 has a problem that it cannot be viewed with a general stereo slide viewer or the like because the left and right screens are arranged at opposite positions.

  Therefore, 3D image data shot by a stereo camera is directly input to a printer to print 3D photographs and 3D prints / slides with the same 3D effect as 3D images displayed on 3D TVs and 3D PCs. Therefore, a technical problem to be solved in order to be reproducible arises, and the present invention aims to solve this problem.

The present invention has been proposed to achieve the above object, and the invention according to claim 1 is a stereo slide mount having a structure in which a slide film is sandwiched between a base frame and a cover frame,
A concave film installation portion is provided around the left and right windows of the base frame, and the upper and lower sides of the slide film are positioned by a step generated in the film installation portion. The slide film has a left screen on the left side and a right screen. The sheet is placed on the right side and a pair of left and right stereo photographs are printed side by side, and a notch or hole provided on the upper or lower side of the slide film is erected on the base frame. The base frame is fitted to the pin, the holes in the cover frame are fitted, the base frame and the cover frame are fixed, and the convex portions around the left and right windows of the cover frame are recessed into the concave portions of the film installation portion of the base frame. A stereo slide mount configured to hold a single film with the left and right screens juxtaposed with the cover frame Subjected to.

  According to this configuration, adjustment work at the time of mounting becomes unnecessary, and anyone can perform the mounting work.

  According to a second aspect of the present invention, there is provided the stereo slide mount according to the first aspect, wherein both left and right ends are formed in a circular arc shape of a part of a circle or a curved shape having a smaller curvature than the circular arc shape.

  According to this configuration, it becomes easy to insert a stereo slide or a stereo photo print into the slot of the ornamental viewer. Moreover, it is possible to prevent the corner portion of the stereo slide from being damaged.

  According to the first aspect of the present invention, a concave film installation portion is provided around the left and right windows of the base frame, and the upper and lower sides of the slide film are positioned by a step generated in the film installation portion. Is placed on the left side, the right screen is placed on the right side, and a pair of left and right stereo photographs are juxtaposed and printed in a single sheet, with a notch or hole provided on the upper or lower side of the slide film, The base frame and the cover frame are fixed by hooking the cover frame with holes on the base frame, and the base frame and the cover frame are fixed. A single film with the left and right screens recorded side-by-side with the base frame and cover frame is held, so the left and right images are juxtaposed. Where is a stereo slide mount to mount stand the integrity of the film, which was printed Te, it can be expected that the work of the mount is an effect that can be easily for many people.

  The invention according to claim 2 is the stereo slide mount according to claim 1 in which the left and right ends are formed in a circular arc shape of a part of a circle or a curved shape having a smaller curvature than the circular arc shape. / A stereo photo print or slide holder is arcuate at both ends, which makes it easier to insert the stereo slide / stereo photo print or slide holder into a slot of an ornamental device (stereo viewer), and Even when the stereo slide / stereo photo print or the slide holder is inserted at an angle, it is possible to prevent locking.

FIG. 1 shows the configuration of a stereo slide / photo print and a stereo photo printer according to an embodiment of the present invention.
The conceptual diagram of the stereoscopic vision which concerns on the technical matter relevant to this invention and an Example. FIG. 2 is a relationship diagram between a reference dimension display screen (large stereoscopic TV shown in FIG. 1) and a stereo camera that transmits standard stereoscopic video data, in which (a) shows a reference dimension display screen, and (b) shows a stereo camera. FIG. Detailed explanatory drawing of FIG. (a) is one Example of a stereo slide production apparatus, (b) is one Example of a stereo slide film. One example of a stereo slide, (a) shows a base frame, (b) shows a state in which the stereo slide is attached to the base frame, and (c) shows a cover frame. (a) shows a stereo photo print sheet with perforated lines, and (b) shows the relationship between the stereo print and the slide holder.

  Hereinafter, embodiments of the present invention will be described in detail. By the way, the matters described here refer not only to the invention according to the claims of the present application but also to the contents including the technical matters related to the invention according to the claims.

  The embodiments of the technology related to the present invention will be described below together with the basic technology of the present invention. A feature of the basic technology of the present invention is that stereoscopic video data can be shared even when the size of the imaging element of the stereo camera, and the display range and screen size of the stereoscopic video display device are different. In order to recognize the sense of distance and dimensions of all stereoscopic images in common, it is necessary to set a reference window (virtual field frame that matches the field of view taken by the left and right photographic lenses) at the time of shooting. Image frame) and send out as standard stereoscopic video data necessary for display. A faithful stereoscopic effect can be reproduced by displaying the standard stereoscopic video data on the display side on a screen having a reference dimension equivalent to the reference window on the photographing side.

For example, in FIGS. 2A and 2B, the width of the reference window Wref is set to W _W , the width of the image Iref in the reference window projected onto the image sensor S is set to W _S , and the width of the reference dimension display screen Eref is set. Assuming W _D , the projection magnification r is r = W _S / W _W , and the display magnification R is R × W _D / W _S , where r × R = 1.
It is to do. According to the above formula, it is understood that it is easy to convert the transmission image data of the stereo camera into standard stereoscopic video data regardless of the width W _S of the image pickup device S.

  FIG. 1 is a conceptual diagram of stereoscopic viewing. If the illustrated large-sized 3D TV (display width 1800 mm) is a television with a reference dimension display screen, the display screens of each size and the arrangement thereof have the relationship shown in the drawing.

  FIG. 3 shows the dimensions and arrangement relationships of FIG. 1 in more detail. FIG. 3 shows the actual size ratio as a dimensional ratio that increases as it approaches the position of the observer. This avoids confusion in drawing.

In FIG. 3, the distance L _X from the observer's eye to the boundary position between the left and right juxtaposed display range and the overlap display range shown in FIG.

Ｌ_Ｘ＝Ｌ_０／（１＋Ｗ_Ｐ０／Ｂ）
の関係となり、Ｌ₀＝２５００ｍｍ、Ｗ_P0＝１８００ｍｍとすれば、瞳間隔が Ｂ＝５８ｍｍのとき
、Ｌ_X＝２５００／(１＋１８００/５８)＝７８，０４mmとなり、瞳間隔がＢ＝７２mmのときは、
Ｌ_X＝２５００／(１＋１８００/７２)＝９６，１５mmとなる。

L _X = L ₀ / (1 + W _P0 / B)
If L ₀ = 2500 mm and W _P0 = 1800 mm, then L _X = 2500 / (1 + 1800/58) = 78,04 mm when the pupil spacing is B = 58 mm, and when the pupil spacing is B = 72 mm Is
L _X = 2500 / (1 + 1800/72) = 96,15 mm.

In the side-by-side display range, a partition for dividing the left and right visual fields is necessary, and the actual viewing distance is almost limited to about 75 mm. Further, since 75 mm is very close to the distance of clear vision, a loupe for adjusting diopter is necessary, and a loupe having a focal length slightly larger than the viewing distance is preferable. An appropriate focal length is about 80 mm. The pupil interval (stereo base) B is
If there is a slight difference among the observers but the viewing distance is large (overlap display range), the slight difference between the left and right distances of the corresponding points of the infinity image and the pupil distance B may be ignored. In the left and right juxtaposed display range, the difference from the pupil interval B is small, but the difference is reduced by adjusting the interval of the diopter adjustment lens.

The left-right screen interval, that is, the picture distance, has the following relationship between the left-right pupil interval B shown in FIG. 3 and the distance L ₀ to the display D _{0 of the} reference dimension. Picture distance D _PN of arbitrary distance L _N to arranged the display D _N,

Ｄ_ＰＮ＝Ｂ（１−Ｌ_Ｎ／Ｌ_０）

の値となる。

_{D PN = B (1-L} N / L 0)

It becomes the value of.

The screen width of each of the left and right is proportional to the distance from the viewer's eyes, but since the viewing angles α shown in the figure sandwiching the display D ₀ are the same for the light rays entering the left and right eyes, each apparent screen shown in FIG. The width is
W _P0 = W _P1 = W _P2 and the same size appears.

  As described above, by displaying the standard stereoscopic video data in the relational arrangement shown in FIG. 1 on the TV of the reference dimension display screen (large TV shown in FIG. 1), the overlap display for displaying the left and right images in an overlapping manner. Data common to all the display ranges from the range to the left and right juxtaposed display range having the left and right independent display screens can be used. In this case, it is only necessary to display the standard stereoscopic video data on the respective displays shown in the figure (position and width) under the conditions defined on the left and right.

FIGS. 2A and 2B are explanatory diagrams of a stereo camera as means for acquiring stereoscopic image data having the relational arrangement shown in FIG. FIG. 2A is a state diagram that is exactly the same as the stereoscopic view of FIG. 1, and is a relationship diagram when FIG. 2B is a stereo camera. Now, a from the display Eref of equality reference window shown in FIGS. 2 (a) to the eye E _L and E _R of the left and right respectively of the observer, the left and right respectively captured from reference window Wref width W _W shown in FIG. 2 (b) A conjugate relationship is established up to the lenses L _L and L _R. Therefore, the image data on the image sensor arranged in the left and right viewing angles α is the same as when a person actually observes the television (the large stereoscopic TV shown) on the reference dimension display screen of FIG. In addition, the size (width) of the image sensor disposed within the viewing angle α is determined by the position in the optical axis direction where the image sensor is disposed.

In FIG. 2B, the width W _S of the image sensor is

Ｗ_Ｓ＝Ｗ_Ｗ×（ｆ＋Δｆ）／Ｌ_Ｗ

で計算される。また、左右の撮像素子の間隔（倒立画像のピクチャーディスタンス）、即ち図示のＤ_Sは、左右の撮影レンズの光軸間距離（レンズディスタンス）をＤ_Lとすれば、

W _S = W _W × (f + Δf) / L _W

Calculated by Further, the distance between the left and right image sensors (picture distance of an inverted image), that is, D _S in the figure, is given by assuming that the distance between the optical axes of the left and right imaging lenses (lens distance) is D _L.

Ｄ_Ｓ＝Ｄ_Ｌ（１＋（ｆ＋Δｆ）／Ｌ_Ｗ）

で計算され、Ｄ_S＞Ｄ_Lの状態になる。立体映像は、遠景〜近景までの全体がはっきり見えるように焦点を調整すべきである。それには、撮影レンズのアパチャー（絞り）の口径を小さく設定してパンフォーカス状態で撮影すべきである。パンフォーカス状態で撮影する場合、上記ｆ＋Δｆは、ｆ＋Δｆ≒としても差し支えない。

D _S = D _L (1+ (f + Δf) / L _W )

And D _S > D _L. The focus of the stereoscopic image should be adjusted so that the entire view from the distant view to the close view can be clearly seen. To do this, the aperture of the taking lens should be set to a small aperture and shot in a pan focus state. When shooting in a pan focus state, f + Δf may be set to f + Δf≈.

  The image projected on the image sensor is in an inverted state, and if it is rotated 180 ° at the left and right positions in order to erect, the distance between the left and right screens, that is, the picture distance (display side = upright image state) is the human pupil width. Smaller than B. In addition, two triangles (two triangles partially overlapping each other) formed by a reference window Wref illustrated in FIG. 2B and a line that passes through the principal points of the left and right photographing lenses and sandwiches the width WW of the reference window Wref. ) And two triangles composed of a line passing through the principal points of the left and right imaging lenses and sandwiching both ends of the left and right imaging elements S and the surfaces of the imaging elements themselves are the principal points of the left and right imaging lenses. Similar to point symmetry. Since the left and right units are symmetrical with respect to the center line O shown in the figure, the left and right optical axes Φ (L) and Φ (R) are equal when the center line O in the figure is folded as a fold line. Then the left and right overlap each other. Accordingly, the stereoscopic video imaged by the stereo camera of FIG. 2B is superimposed on the same screen position of the TV (large stereoscopic TV shown in the figure) of the reference dimension display screen of FIG. When viewing the left and right screens with the left and right eyes using the field separation glasses, the corresponding points of the infinity image are automatically displayed at the human pupil interval.

Therefore, it is possible to reproduce the optimal three-dimensional image. It should be noted that no special method is required to project the reference dimension display screen at the same position, and the image on the image sensor S shown in FIG. 2B is displayed on the display shown in FIG. The screen width W _D of the display D ₀ and the image sensor width W _S may be displayed at a magnification of W _D / W _{S which} is a simple ratio.

Also, the left and right screen widths of each size shown in FIG. 1 are determined by the ratio of the disposition distance of each display device and the distance to the TV of the reference dimension display screen. In FIG. 3, the screen width W _PN for an arbitrary installation (viewing) distance L _N is

Ｌ_Ｎ／Ｌ_０＝Ｗ_ＰＮ／Ｗ_Ｐ０

の単純化であるので、算出は容易である。

L _N / L ₀ = W _PN / W _P0

Since this is a simplification, calculation is easy.

  As shown in FIGS. 1 and 2, the stereoscopic image should display the corresponding points at infinity in the entire range at the human pupil interval, so that the infinity image = pupil interval = light of the left and right photographing lenses. The distance from the corresponding point at infinity incident on the left and right photographing lenses of the stereo camera is parallel to each other, so the corresponding point at infinity projected on the image sensor is equal to the distance between the optical axes. Become. Therefore, in order to set the distance between the corresponding points at infinity on the left and right display screens to the human pupil distance regardless of the display size, it corresponds to the center of the optical axis of the left and right photographing lenses on the left and right imaging elements. It is only necessary to set the position on the display screen so that the left and right intervals are equal to the human pupil interval. That is, in any 3D display device of any screen size, the right and left optical axis intervals corresponding to the imaging unit between the left and right sides of the playback screen are equal to the human pupil interval between the right and left optical axes of the stereo camera. It is to display in the dimension.

  The above description is the basic configuration of the present invention, and it is possible to obtain a sense of realism equivalent to a case where a person views a real scene in front of the eyes.

When producing a stereo slide / photo print, it may be printed to an arbitrary size within the “horizontal juxtaposed display range” shown in FIG. 1, and the left and right screen widths W _P2 are shown in FIG. 1 and FIG.
L _N / L ₀ = W _PN / W _P0 → L ₂ / L ₀ = W _P2 / W _{P0 in} [Formula 5]
The simple ratio can be calculated.

In addition, the left and right screen spacing D _P2 is
D _PN = B (1-LN / L0) in the above [Expression 2] → D _P2 = B (1-L ₂ / L ₀ )
It can be calculated with That is, in [Formula 2], D _PN = D _P2 , and
Since L _N = L ₂ , by substituting D _P2 into D _PN and substituting L ₂ into L _N in the above [Equation 2], the left and right screen spacing is D _P2 ,
It is determined by the mathematical formula of D _P2 = B (1−L ₂ / L ₀ ). Note that the left and right double-sided spacing _DPN is not shown in FIG. 3 because it is a variable determined according to the value of the distance _LN , which is an arbitrary variable.

FIG. 4A is an example of a stereo slide printer (silver halide method), and FIG. 4B is an example of a printed stereo slide. Wherein as described in Example 1, to produce a stereo slide, D ₂ of the standard stereoscopic video data obtained by reducing the width W _P2 shown to be displayed over the display D ₀ in FIG. 3 (L) And D ₂ (R) may be displayed at the interval of D _P2 , and left and right images based on standard stereoscopic image data are sequentially displayed on the display 41 shown in FIG. The image 42 is projected onto the film 43 by 42, and the left image 47 and the right image 48 are juxtaposed and recorded. The interval between the left image 47 and the right image 48 to be recorded may be set to the interval D _P2 , and the set interval may be measured by measuring the winding by the winding drum 46 (a method of sandwiching with a roller or the like). However, for accuracy, it is better to move the slider 45 sliding on the guideway 44 by a predetermined amount and sequentially expose. If the next pair of images is exposed by the post-exposure take-up drum 46, the take-up accuracy is not required to be so high.

Since the display image on the display 41 is inverted by 180 ° by the projection lens 42 and projected onto the film 43, it must be displayed in an inverted image state on the display 41. Further, the element of the display 41 is desirably an element having a high aperture ratio such as DMD or LCOS, but a TFT liquid crystal or the like can also be used. When TFT liquid crystal is used, a liquid crystal with as large a screen size as possible should be adopted and used after being reduced and projected. This is to increase the number of pixels to increase the resolution, but in any display element, the resolution is significantly improved if the three primary colors R, G, and B are exposed in a time-sharing manner (because it is a still image, 3). There is no problem even if the primary color rewriting speed is slow.) When the film 43 is a positive film, exposure is performed with three primary colors of R, G, and B. However, when a negative film is used, it is natural that exposure is performed with complementary colors of C, M, and Y. However, since C = G + B M = B + R Y = R + G, the display element can be used even in primary colors of R, G, B after all.

  The display 41 should be as large as possible. However, the display elements such as DMD and LCOS described above are originally display elements for enlargement projection, so they are approximately the same size in a stereo slide and are relatively small. Even if the element is used to make a large stereo slide, the enlargement ratio is about 3 times.

  FIG. 4B shows a film 43 that is cut after each pair of stereo slides after development, and a positioning index line 410 for the mount is preferably printed at the center of the film 43 at the same time. Further, a positioning notch 411 may be cut at the time of printing, and this notch 411 should be cut prior to film production when using a sheet film for each sheet.

  Even when using roll film or sheet film, when accepting electronic data and transferring it to a silver salt film, it is video data only because it is not accompanied by substance such as film. In the case of recording only, the post-development owner and mailing (returning) destination are unclear. For this reason, an ID code is sent as accompanying data at the same time as the stereoscopic video data, and the ID code is recorded by a one-dimensional or two-dimensional code (known) in an intermediate portion 49 between the images 47 and 48 on the film 43 in FIG. It is to be. The ID may be registered in advance, or may be sent as accompanying information from a PC via a communication line. After development, this ID code is read with a code reader, which saves and automates the work of sorting and shipping (returning) the finished slide (for example, automatically reading the address on the return envelope by reading the two-dimensional code) Printable).

  FIG. 5 shows a mount for holding the film of FIG. 4B, for example, a resin molded product. FIG. 5A shows a base frame 50 having two openings, a left window 52 and a right window 53. Further, a film installation portion 51 is formed in a concave shape around the two windows, and a connecting pin 54 is erected on the outside thereof. The base frame is formed with a film alignment mark 55 and a film positioning projection 56 (only one of the positioning mark 55 and the positioning projection 56 may be provided).

  FIG. 5B shows a state in which the film 43 shown in FIG. 4B is attached to the film installation part 51 of the base frame 50, and the notch 411 of the film 43 projects from the base frame 50. Locked by the protrusion 56.

  FIG. 5C shows a cover frame 500 having two openings, a left window 502 and a right window 503, and convex portions 501 are formed around the left and right windows 502 and 503. The convex portion 501 is inserted into the concave portion 51 of the base frame 50 to sandwich the film 43. A hole 504 is formed in the peripheral portion of the cover frame. When the hole 504 is inserted into the pin 54 of the base frame 50, the base frame 50 and the cover frame 500 are fixed, and the slide film 43 is integrated into the front and back sides. Is retained.

  FIG. 6A shows a paper 60 of a sublimation type thermal printer, for example. Since the sublimation type thermal printer repeatedly prints the number of times for each color in order to transfer the dye for each color, the paper feed mechanism such as a roller has poor accuracy and causes color misregistration. Therefore, it is necessary to perform printing by moving the carriage on which both ends of the print paper are pressed and the paper is placed. The illustrated tab 62 is a portion that grips the print paper 60 and is an unnecessary portion after printing and needs to be cut off. The illustrated perforated lines (commonly referred to as perforations) 61 are placed at both ends of the print paper 60. Thus, if the tear is cut along the perforated line, both ends of the stereo photo print are formed in a circular arc shape of a part of the circle.

  The structure of the printer itself can be a conventional thermal printer. For example, in FIG. 6A, printing is performed in the direction indicated by the arrow A in the main scanning (thermal head scanning), and in the direction indicated by the arrow B in the sub-scanning (feeding paper) to print one of the left and right sides. After that, it is sufficient to print the other one by the amount corresponding to the screen interval.

  FIG. 6B operates smoothly even when it is inserted at an angle as shown in the figure due to the relationship between the stereo slide / print 60 and the slide holder 63. Even if the dimensional relationship between the slide holder and the slide is the same and the gap is zero, the slide holder and the slide are not locked. In addition, a rectangular plate-like object such as a stereo slide is regularly observed that the corner portion is damaged, but the damage can be prevented by making both ends arc-shaped.

  It should be noted that the present invention can be variously modified without departing from the spirit of the present invention, and the present invention naturally extends to the modified version.

  Stereoscopic video data can be transmitted via a communication line, and stereo slides can be easily transmitted to a development station for development, and the slide film is inserted into the film installation recess of the base frame, and the base frame and cover frame By holding a single film with side-by-side recording of the screen, mounting the integrated film on which the left and right images are juxtaposed is mounted on a mount base, so that the convenience of mounting and easy personal printing is expected. can do.
