A7 _____B7 _ 五、發明説明（） 發明背景： 本發明係關於一種立體幻燈片框，特別是一種經由遮 蔽左右畫面之外側，達到顯示正確三度空間影像目的之立 體幻燈片框。 一種由立體照相機拍攝之立體幻燈片，該照相機之左 右透鏡之光軸間距離係為固定，而形成畫面之未重叠部份。 由於左右攝影透鏡不同之視界範圍，該非重疊部份之攝影 範圍不能在左右攝影畫面外側達成一致。該非重疊部份， 並不具有在立體幻燈Η觀察器内形成之三度空間影像。如 果未將立體幻燈片之非重叠部份遮蔽，直接由雙眼觀看，-將可看到垂直之線條，係為在畫面窗邊緣重叠部份與非重 疊部份交界處重疊之現象，此現象將影響三度空間影像之 品質。為了避免前述狀況發生，因此具有使立體幻燈片框 之畫面窗寬度稍微小於幻燈底片之畫面寬度，Μ遮蔽非重 疊部份之方法。 隨物體距離之遞減，該被遮蔽之非重叠部份之寬度亦 隨之遞增，將對於左右畫面之合成產生嚴重之影響。因此 才有複數種具有不同畫面窗寬度之立體幻燈片框。再從這 些立體幻燈片框中選擇出具有適當遮蔽量之畫面窗之片框， 再將幻燈底Η裝設其中。然而人們無法用眼睛輕易判斷出 每對被切下置於片框中之幻燈底片之遮蔽量，因此經常發 生幻燈片框選擇錯誤之情形。 再者，為了獲得立體照相適當之三度空間效果，對於 左右畫面合成效果影響最大之物像距離，應該位於距離立 -2- ^-- { (請先Μ讀背面之注意事項再填寫本頁) .1Τ 碌 » In 1^1 m 經濟部中央標準局員工消費合作社印聚 A7 B7五、發明説明（） 體幻燈片框之左右畫面窗之相等位置。當物像位置與左右 畫面距離不同時，一自然之三度空間效果將被抵銷。然而 習用之立體幻燈片框，並無用來決定底片左右位置之標準， 因此無法輕易地使底片正確定位。 為了排除習用立體幻燈片框之缺點，本發明人乃揭示 一種立體幻燈片框及一種配合一畫面遮蔽量導引裝置/立 體幻燈片觀察器使用之幻燈片框结構。該種立體幻燈片框 结構係用於立體照相機拍攝之立體幻燈片，且底片之孔眼 與攝影畫面間保持相同之相對位置關係。該立體幻燈片框 係由一底框與一蓋框構成；該底框在左右盡面窗之邊緣設-有複數之定位點以定位底片，該蓋框具有相同之左右畫面 窗間隔距離，但畫面窗之寬度係為逐漸改變。 使用該畫面遮蔽量導引裝置/幻燈片觀察器觀察三度 空間影像，係可變換立體幻燈晝面Μ外區域之遮蔽量，Μ 決定適當之遮蔽量。 經由該畫面遮蔽量導引裝置/立體幻燈片觀察器決定 底Η之遮蔽量之後，使底片之孔眼與底框之定位點结合在 一起，完成定位，並根據決定之遮蔽量選擇出該具有適當 畫面窗之蓋框，與該底框接合在一起。然後，底片將被固 定在片框中，且左右底片外側之非重叠部份將受到遮蔽， 即可獲得一正確之三度空間效果。 、 由此可見，該立體幻燈片框能夠正確且容易地在裝置 時完成定位。該蓋框係具有複數類型之畫面窗寬度，但具 有相同之左右晝面窗間隔距離。因此當畫面窗寬度較小時， -3- ---------^------t------i (請先閱讀背面之注意事項再^寫本頁) 本紙張尺度適用中國國家標準（CNS ) A4規格（210X297公釐） 經濟部中央標準局貝工消費合作社印製 A7 __B7_ 五、發明説明（） 左畫面與右畫面中心之距離亦較小，而雙眼之角度變化正 取決於畫面中心間之距離。 當在一般情況觀察影像時，左右畫面中心距離之變化 並不是問題。然而，當立體幻燈Η畫面中心間距離有較大 之差異時，眼球必須在觀察時間内承受一集中角度内之改 變，由於視覺殘留之原因*將使該觀察者感覺到不適或疲 勞。 根據上述乃存在一待解決之技術問題，有必要提供一 種能夠方便裝置與定位之操作，並且使觀察者能夠輕鬆觀 察影像不致疲勞之立體幻燈片框。本發明之目的即在於解 決上述問題。 發明概述： 為達成上述目的，本發明揭示一種用Μ裝設立體照相 機所拍攝之立體幻燈片之立體幻燈片框，該幻燈底片之孔 眼與左右攝影畫面間保有相同之相對位置。該幻燈片框係 由一具有二平行排列之矩形畫面窗之底框，與一蓋框所構 成；其中該底框於裝設底片之表面設有複數定位點，係用 Κ與該幻燈底片之孔眼接合，以便固定二幻燈底片；該蓋 框於持住底Η之表面設有與該複數定位點相對應之複數定 位孔，係用以固持該幻燈底片。前述定位點與前述定位孔 係可相互嵌合，藉此將該底框與該蓋框結合在一起。其中 一由複數類型之立體幻燈片框構成之片框糸統，其中各片 框係具有不同之畫面窗寬度，係隨畫面之寬度遞減，並且 左右畫面窗中心之間距離始終保持一致。藉由前述定位點 -4- 本紙張尺度適用中國國家標準（CNS ) A4規格（210X297公釐） I---------1------1Τ------0 f -(讀先閱讀背面之注意事項再續寫本頁) 經濟部中央標準局員工消費合作社印聚 A7 B7__五、發明説明（） 與前述定位孔在該複數類型之立體幻燈片框内之配置，將 使左右畫面窗之垂直之内端緣與底Η畫面之内緣成為一致 且左右幻燈片外側之遮蔽部份將隨該複數類型之立體幻燈 片框之不同畫面窗寬度而調整。 圖示說明： 圖1(a), 1(b), 1(c), 1(d)係本發明之立體幻燈片框 之前梘圖。 圖2揭示一具有最大畫面窗寬度之立體幻燈Η框，其 中圖2 (a)為一前視圖，·圖2(b)為一側面視圖；圖2(c)為一 底視圖；圖2 (d)為一後視圖。 圖3揭示圖2之立體幻燈片框之蓋框，其中圖3 U)為 一前視圖；圖3(b)為一側面視圖；圖3(c)為一底視圔；圖 3(d)為一後視圖。 圖4揭示圖2之立體幻燈片框之底框，其中圖4 (a)為 一前視圖；圖4(b)為一側面視圖；圖4(c)為一底視圖；圖 4(d)為一後視圖。 圖5揭示本發明之立體幻燈片框之一定位裝置，係由 幻燈片支承座內之一小機械彈簧與立體幻燈片框内之垂直 凹槽所構成。 圖6揭示本發明另一實施例之定位裝置•係由幻燈片 支承座上之凸出部及幻燈片框上之一凹缺所構成。 圖7揭示習用立體幻燈片框裝置失敗之情形。 圖8揭示本發明之再一實施例，其中圖8 (a)係為底框 之前視圖；8(b)為該底框之側面視圖；8(c)為蓋框之前視 圖；8(d)為該蓋框之側面視圖。 __ " R — -

A7 _____B7 _ V. Description of the invention () Background of the invention: The present invention relates to a three-dimensional slide frame, in particular, by shielding the left and right sides of the left and right screens to achieve the correct three-degree display. Stereo slide box for spatial imaging purposes. A stereo slideshow taken by a stereo camera. The distance between the optical axes of the left and right lenses of the camera is fixed to form the non-overlapping part of the picture. Due to the different horizons of the left and right photographic lenses, the photographic range of the non-overlapping portion cannot be agreed outside the left and right photographic frames. The non-overlapping part does not have a three-dimensional spatial image formed in a stereoscopic slide projector. If the non-overlapping part of the three-dimensional slide is not covered, look directly with both eyes,-you will see vertical lines, which is the phenomenon of overlapping at the border of the overlapping part and non-overlapping part of the edge of the screen window. This phenomenon Will affect the quality of three-dimensional space image. In order to avoid the aforementioned situation, there is a method for making the width of the screen window of the three-dimensional slide frame slightly smaller than the screen width of the slide film, and M to shield the non-overlapping part. As the distance of the object decreases, the width of the masked non-overlapping portion also increases, which will have a serious impact on the composition of the left and right pictures. Therefore, there are a plurality of stereoscopic slide frames with different picture window widths. From these three-dimensional slide frames, select the frame of the picture window with the appropriate amount of shielding, and then install the slide base. However, people cannot easily judge the shielding amount of each pair of slide negatives cut into the frame with their eyes, so often the wrong selection of the slide frame occurs. In addition, in order to obtain the appropriate three-dimensional effect of stereo photography, the distance of the object image that has the greatest effect on the left and right screen synthesis effect should be located at the distance of ^ ^-{(Please read the precautions on the back before filling this page ) .1Τ »» In 1 ^ 1 m The Consumers' Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs of the People's Republic of China Printed A7 B7 V. Description of the Invention () The left and right screen windows of the body slide frame are equally spaced. When the position of the object image is different from the distance between the left and right frames, the natural three-dimensional effect will be offset. However, the conventional three-dimensional slide frame does not have a standard for determining the left and right positions of the negative, so the negative cannot be easily positioned correctly. In order to eliminate the shortcomings of the conventional three-dimensional slide frame, the present inventor discloses a three-dimensional slide frame and a slide frame structure used in conjunction with a picture shielding amount guide device / a stereo slide viewer. This stereoscopic slide frame structure is used for stereoscopic slides shot by a stereo camera, and the perforations of the negative film and the photographic picture maintain the same relative positional relationship. The three-dimensional slide frame is composed of a bottom frame and a cover frame. The bottom frame is provided with a plurality of positioning points on the edges of the left and right windows to locate the negative. The cover frame has the same distance between the left and right screen windows, but The width of the picture window is gradually changed. Observing the three-dimensional space image by using the screen occlusion amount guide / slide viewer can change the occlusion amount of the area outside the M of the stereo slide daytime, and M determines the appropriate occlusion amount. After determining the masking amount of the bottom frame through the screen masking amount guide device / stereoscopic slide viewer, the eyelet of the negative film is combined with the positioning point of the bottom frame to complete the positioning, and the appropriate masking amount is selected according to the determined masking amount. The cover frame of the picture window is joined with the bottom frame. Then, the negative will be fixed in the frame, and the non-overlapping parts on the outside of the left and right negatives will be shielded, and a correct three-dimensional space effect can be obtained. It can be seen that the three-dimensional slide frame can be correctly and easily positioned during installation. The cover frame has a plurality of types of picture window widths, but has the same distance between the left and right daytime window. Therefore, when the width of the picture window is small, -3- --------- ^ ------ t ------ i (Please read the precautions on the back before writing this page) This paper size applies to Chinese National Standard (CNS) A4 (210X297 mm).

Description of the invention () The distance between the center of the left screen and the right screen is also small, and The angle of the eye changes depending on the distance between the center of the picture. When viewing images in general, the change in the distance between the left and right screen centers is not a problem. However, when there is a large difference in the distance between the center of the three-dimensional slideshow and the screen, the eyeball must undergo a change within a concentrated angle during the observation time. Due to the residual vision *, the observer will feel uncomfortable or tired. According to the above, there is a technical problem to be solved. It is necessary to provide a three-dimensional slide frame that can facilitate the operation of the device and positioning, and enable the observer to easily observe the image without fatigue. The object of the present invention is to solve the above problems.

Description of the invention () The width of the distance between the larger left anchor point 6 and the right anchor point 6 (P0, P1 , P2, P3), therefore, there is an increased gap between the left and right negatives, and at the same time, the outside of the left and right negatives has an increased amount of shielding. When installing a three-dimensional slideshow, the masking amount of the negative film is determined by the aforementioned masking amount guide device. Using conventional or any other masking amount setting method, a window width that is related to the masking amount guide device will be selected. 3D Slide Box 1. Then install the bottom case on the left and right daylight windows 5L, 5R of the bottom frame 3, and then place the cover frame 2 on the bottom frame 3. • The plurality of positioning holes 7 and the plurality of positioning points 6 are embedded in each other. Then, the cover frame 2 and the bottom frame 3 are combined together. The bottom frame 3 can be folded in half by the vertical groove 8. Therefore, both the left and right halves are applicable: First, the positioning process of the positioning point 6 and the positioning hole 7 can be easily completed, and the installation operation can be completed quickly. On the other hand, the surface of the cover frame 2 is a flat surface without a folding groove, and can easily write a title or a record about photography. The gap between the left picture window 4L and the right heavy plane window 4R of the cover frame 2 may further be provided with a recessed portion, and a title or a beer label may be placed on the recessed portion. In the conventional stereo slide viewer, the width of the inner part of the slide support base is slightly larger than the width of the stereo slide frame, so that the stereo slide frame can be installed. Due to the difference in size, the left and right positions of the stereoscopic slide frame are often unstable in many cases. However, as shown in FIG. 5, when the positioning spring 12 of the slide support base 11 of the slide viewer is brought into contact with the vertical groove 8 of the three-dimensional slide frame 1, the three-dimensional slide frame can be correctly placed. 1 before and after left and right parts. * 8- (Please read the notes on the back before writing this page) This paper size is applicable to China National Standard (CNS) Α4 size (210 × 297 mm) Printed by A7 B7, Shellfish Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs Explanation () Figure 6 discloses another positioning device, in which a notch 9 is provided at the center of the bottom of the three-dimensional slide frame 1A, and the slide support 11 of the slide viewer is provided with a protruding portion 11a, and the protruding portion Ua It will be matched with the recess 9, thereby positioning the three-dimensional slide frame 1A. Referring to FIG. 6, the upper end of the protruding portion 11 a has a semi-circular shape. The three-dimensional slide frame 1M is installed from above the slide support base 11, so the recess 9 can be smoothly combined with the protruding portion 11 a. Together. The height of the recess 9 is slightly larger than the height of the protrusion 11a, so the bottom of the three-dimensional slide frame 1A will not be suspended on the bottom surface of the slide support 11. In addition, the recess has the effect of easily identifying the upper and lower sides of the three-dimensional slide frame 1A. As shown in FIG. 6, when the stereo slide frame is installed in the slide support of the slide viewer, when the stereo slide frame is pushed obliquely, the corner of the stereo slide frame M and the slide support Η often occur. When the left and right wall surfaces are in contact with each other, the three-dimensional slide M frame M is stuck due to friction resistance. Therefore * a positioning device composed of the notch 9 and the protruding portion 11a can prevent the three-dimensional slide frame from departing from the left and right directions, even if the internal width of the slide support base 11 is considerably larger than the three-dimensional slide frame 1A The width can be easily loaded into a slide frame. When the eyelet of the base is circular or oval extending in the horizontal direction, the diameter of the cylindrical positioning point 6 must be selected to maintain the base in the correct position in the horizontal direction and the position of the negative in the vertical direction. It only depends on anchor point 6. However, when the film has perforations extending vertically, such as the 135 film, the positioning reference may be lost in the vertical direction due to the circular diameter or the shape of the positioning point 6. -9- The paper size is applicable to Chinese National Standard (CNS) Α4 specification (210 × 297 mm) L --------- ¥ ------ 1T ------ ^ *-{(Please ask (Please read the notes on the back before filling this page) A7 _B7___ printed by the Shellfish Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs 5. Description of the invention () The embodiment disclosed in Figure 8 and Figure 9 is to solve the above problems. See Figures 8 (a) and 8 (b). In addition to the positioning point 6 which limits the horizontal position of the film, the bottom frame 3 is also provided with a positioning point 13 which limits the vertical position of the bottom frame. Referring to FIGS. 8 (c) and 8 (d), the cover frame 2 is provided with positioning holes 7,14, and M is matched with the positioning holes 6,13. Referring to Fig. 9, the bottom portion 3 has a recessed portion 15 at a center portion in the vertical direction, and the recessed portion 15 has the same width as the vertical direction of the negative film. By placing the negative on the recessed portion 15, the position of the negative in the vertical direction can be limited, as shown in FIG. To sum up | the three-dimensional slide frame of the present invention, the parallax of the object can be accurately corrected by the three-dimensional slide M frame selected when the film is installed, and the screen window width of the slide frame is guided by a mask Device or similar device. Even if the picture windows have different widths, the center of the left picture and the right picture always remain the same distance. Therefore, even if different stereoscopic slide frames with different screen obscuration amounts must be frequently observed, the viewing angles of the left and right eyes remain the same, making the eyes less prone to fatigue. It must be stated here that the present invention is not limited to the above-mentioned embodiments.
