Description

本発明は、立体視を観賞する立体視ビュアに関する。 The present invention relates to a stereoscopic viewer for viewing stereoscopic vision.

従来の立体視用のビュアは、図１３に示すようにカードを開いて一対の接眼レンズ系２ａ、２ｂと人間の両眼の視差に基いて制作された少なくとも２枚の画像３ａ、３ｂとを対向させて、接眼レンズ系２ａ，２ｂから透視することで立体視を観賞するカードまたは冊子折り曲げ式の立体視用ビュアがある。 As shown in FIG. 13, the conventional viewer for stereoscopic viewing includes a pair of eyepiece systems 2a and 2b and at least two images 3a and 3b produced based on the parallax between human eyes.

しかしながら、図１３に示すビュアにあっては、一方の手で手前の透視部１１を他方の手で奥側の画像保持部１２を持って観賞するので、腕が疲れると同時にビュアが不安定になるという問題があった。 However, in the viewer shown in FIG. 13, the viewer sees the front fluoroscopic part 11 with one hand and the image holding part 12 on the back side with the other hand, so that the arm becomes tired and the viewer becomes unstable. There was a problem of becoming.

あるいは、図１４に示すビュアにあっては、横向きの多角形断面の筒状形態の基体の上部と下部を両手の親指と人差し指で挟んで持つので、断面形状が構造的に不安定になり易い問題があった。更に、透視部１１と画像保持部１２とが上部連接部１３，１４で連接しているので、画像３ａ、３ｂに外光が当たらず暗くて見難いという問題があった。 Alternatively, in the viewer shown in FIG. 14, the cross-sectional shape is likely to be structurally unstable because the upper and lower portions of the cylindrical base having a horizontal polygonal cross section are sandwiched between the thumb and index finger of both hands. There was a problem. Further, since the fluoroscopic part 11 and the image holding part 12 are connected by the upper connecting parts 13 and 14, there is a problem that the images 3a and 3b are not exposed to external light and are dark and difficult to see.

更に、図１３および図１４に示すビュアは立体視観賞時に立体視画像が平面であり、立体視効果が小さいという問題があった。 Further, the viewers shown in FIGS. 13 and 14 have a problem that the stereoscopic image is flat at the time of stereoscopic viewing, and the stereoscopic effect is small.

本発明は上記の目的を達成するために第１の課題解決手段は、立体視ビュアの人間の両眼の視差に基いて制作された少なくとも２枚の立体視画像または前記立体視画像を保持する画像保持部の上辺および下辺ある折線を前記画像保持部を基点にして凹状の曲線にし、収納時には前記凹状の曲線の折り線を開いて前記立体視画像または前記画像保持部を平面状態を保ち、立体視観察時には前記凹状曲線の折線がビュア内方に谷折りになることで、前記立体視画像または前記画像保持部がビュア内方に凹面状に湾曲しながら、略人間の両眼幅離した一対の接眼光学系を設えた透視部に相対面して前記接眼光学系の焦点位置を所定の位置に保持し、前記透視部と前記画像保持部とを、上部を上部保持部で下部を下部保持部でそれぞれ連接する構成で折畳み可能な前記立体視ビュアが３次元的構造になり強固になり観賞し易くなると共に、前記立体視画像が内方の湾曲面になることで曲面スクリーンになる。 In order to achieve the above object, the first problem solving means holds at least two stereoscopic images produced based on the parallax of human eyes of a stereoscopic viewer or the stereoscopic images. The folding line on the upper side and the lower side of the image holding unit is formed into a concave curve with the image holding unit as a base point, and when stored, the folding line of the concave curve is opened to keep the stereoscopic image or the image holding unit in a planar state, When the stereoscopic observation is performed, the folding line of the concave curve becomes a valley fold inward of the viewer, so that the stereoscopic image or the image holding unit is curved in a concave shape inward of the viewer, and the human eyes are separated from each other. The focal position of the eyepiece optical system is held at a predetermined position so as to face a see-through portion provided with a pair of eyepiece optical systems. In the structure that connects with each holding part Together with the stereoscopic viewer capable fold is easily watch becomes stronger becomes three-dimensional structure, the stereoscopic image is curved screen by being a curved surface of the inner.

また、第２の課題解決手段は、上記の手段の収納時に折畳む前記凹状の曲線の折り線を固定にして折畳まない構成にしても良く、その場合は収納用の折線は無く、前記立体視画像または前記画像保持部がビュア内方に凹面状に湾曲し、略人間の両眼幅離した一対の接眼光学系を設えた透視部に相対面して前記接眼光学系の焦点位置を所定の位置に保持する構成で、一体型の３次元的構造になり強固になり観賞し易くなる。 Further, the second problem-solving means may be configured not to fold by fixing the fold line of the concave curve that is folded when the above means is stored, in which case there is no folding line for storage, The stereoscopic image or the image holding unit is curved in a concave shape inward of the viewer, and faces the fluoroscopic unit provided with a pair of eyepiece optical systems that are substantially separated from the eyes of the human. With a configuration in which it is held at a predetermined position, it becomes an integrated three-dimensional structure, which is strong and easy to watch.

また、第３の課題解決手段は、更に前記立体視ビュア上部に採光窓を設けた構成で、前記立体視画像に外光を当てて立体視を見易くする。 Further, the third problem solving means is configured such that a daylighting window is further provided at the upper part of the stereoscopic viewer, and external light is applied to the stereoscopic image to make it easy to see the stereoscopic view.

また、第４の課題解決手段は、上述の立体視ビュアの立体視画像として立体視画像が印刷または貼着された交換可能な立体視カードを用意する。前記立体視カードは装着前は平面であるが、前記立体視ビュアに装着後は曲面になって前記立体視ビュア内側面に収まり安定する。交換可能な立体視カードで多数の立体視画像を観賞できる。 The fourth problem solving means prepares a replaceable stereoscopic card on which a stereoscopic image is printed or stuck as a stereoscopic image of the above-described stereoscopic viewer. The stereoscopic card is flat before being mounted, but after being mounted on the stereoscopic viewer, the stereoscopic card becomes a curved surface and fits on the inner surface of the stereoscopic viewer and is stable. A large number of stereoscopic images can be viewed with interchangeable stereoscopic cards.

また、第５の課題解決手段は、上述のように立体視観賞時に前記立体視画像が凹状の二次曲面になる曲面スクリーンのような強い立体視効果が得られるが前記立体視画像に幾何歪みが発生する弊害が出る。そこで立体視観賞時の前記立体視画像の凹状の二次曲面に合わせて前記立体視画像に幾何補正を施す処理をする。前記処理で前記立体視画像が湾曲面になることによって新たに発生する歪みを低減して、歪みの少ない立体視を観賞できる。 Further, as described above, the fifth problem solving means can obtain a strong stereoscopic effect such as a curved screen in which the stereoscopic image becomes a concave quadric surface during stereoscopic viewing as described above, but the stereoscopic image has a geometric distortion. The harmful effect that occurs occurs. Therefore, a process of performing geometric correction on the stereoscopic image is performed in accordance with the concave quadric surface of the stereoscopic image during stereoscopic viewing. By the processing, the distortion that is newly generated when the stereoscopic image becomes a curved surface is reduced, and stereoscopic vision with less distortion can be viewed.

また、第６の課題解決手段は、上述のように立体視観賞時に前記立体視画像が凹状の二次曲面になると前記立体視画像に奥行き差が生じる。接眼レンズ系の焦点位置を左右それぞれの立体視画像の中心に焦点距離を合わせると、安価な単凸レンズでは立体視時に中心部のみに焦点が合い周辺部がボケている立体像を観賞する。
そこで、前記接眼レンズ系の焦点位置が、立体視用画像の中心から左立体視用画像の左端辺（右立体視画像の右端辺）までの間の位置に有り、好ましくは左立体視用画像の前記左端辺（右立体視画像の前記右端辺）から１／４の位置に合わせる。または、前記接眼レンズ系の焦点位置が、立体視用画像の中心から左立体視用画像の右端辺（右立体視画像の左端辺）までの間の位置に有り、好ましくは左立体視用画像の前記右端辺（右立体視画像の前記左端辺）から１／４の位置に合わせる。この構成で立体視観賞時にピントが合って見える領域が広くなり、立体像が広く感じられる効果がある。Further, according to the sixth problem solving means, when the stereoscopic image becomes a concave quadric surface during stereoscopic viewing as described above, a difference in depth occurs in the stereoscopic image. When the focal distance of the eyepiece lens system is adjusted to the center of each of the left and right stereoscopic images, an inexpensive single-convex lens can view a stereoscopic image in which only the central portion is focused and the peripheral portion is blurred during stereoscopic viewing.
Therefore, the focal position of the eyepiece lens system is at a position between the center of the stereoscopic image and the left end side of the left stereoscopic image (the right end side of the right stereoscopic image), preferably the left stereoscopic image. To the position of ¼ from the left end side (the right end side of the right stereoscopic image). Alternatively, the focal position of the eyepiece lens system is in a position between the center of the stereoscopic image and the right end side of the left stereoscopic image (left end side of the right stereoscopic image), preferably the left stereoscopic image. To the position of ¼ from the right end side (the left end side of the right stereoscopic image). With this configuration, there is an effect that a region that is in focus when viewing stereoscopically is widened, and a stereoscopic image is felt widely.

また、第７の課題解決手段は、前記立体視ビュアを頭部に装着する手段を設けて頭部装着型の立体視ビュアとすることが可能となる。 The seventh problem-solving means can be a head-mounted stereoscopic viewer by providing means for mounting the stereoscopic viewer on the head.

本発明によれば、収納時に平坦に収納可能な折畳式立体視ビュアに係わらず、立体視観賞時に立体視ビュアの透視部１１または画像保持部１２の少なくとも一方が曲面になることで前記立体視ビュア基体が３次元的な頑丈な構造になる効果と同時に、画像保持部１２を曲面とすることで画像３ａ、３ｂが曲面になり、曲面スクリーンのような大きな立体視効果を奏する。 According to the present invention, regardless of the foldable stereoscopic viewer that can be stored flat during storage, at least one of the fluoroscopic part 11 or the image holding unit 12 of the stereoscopic viewer becomes a curved surface during stereoscopic viewing, so Simultaneously with the effect that the viewer base body has a three-dimensional sturdy structure, the images 3a and 3b are curved by making the image holding unit 12 a curved surface, thereby producing a large stereoscopic effect like a curved screen.

更に、立体視ビュアを折畳式にしないで３次元的な形状を維持すれば剛性が低下しない効果奏する。 Furthermore, if the three-dimensional shape is maintained without making the stereoscopic viewer foldable, the rigidity is not lowered.

更に、立体視ビュア基体上部に採光部を設けると前記立体視画像が観賞し易くなる効果を奏する。その上、前記立体視ビュア基体が３次元的な頑丈な構造であるので、採光部が開口していても力学的な強度が低下しない。 Furthermore, if a daylighting unit is provided on the upper part of the stereoscopic viewer base, the stereoscopic image can be easily viewed. In addition, since the stereoscopic viewer base has a three-dimensional sturdy structure, the mechanical strength does not decrease even if the daylighting portion is open.

更に、前記立体視画像を交換可能な立体視カードにすると、多数の立体視画像が観賞できる効果を奏する。 Furthermore, when the stereoscopic card is a replaceable stereoscopic card, there is an effect that a large number of stereoscopic images can be viewed.

更に、前記画像３ａ、３ｂが立体視観賞時に曲面になるので幾何学的な歪みが発生するが、前記画像３ａ、３ｂを立体視観賞時の視点から最適に見えるように歪み補正を施すことで不自然な歪みが無くなり、更なる曲面スクリーンによる大きな立体効果を奏する。 Furthermore, since the images 3a and 3b are curved when viewed stereoscopically, geometric distortion occurs. However, by correcting the distortion so that the images 3a and 3b appear optimally from the viewpoint when viewed stereoscopically. Unnatural distortion is eliminated, and a large three-dimensional effect is achieved by a further curved screen.

更に、下述する所定の位置に接眼レンズ系２ａ、２ｂの焦点距離を合わせると、低価格の凸レンズに係わらずピントが合って見える領域が広い立体視効果を奏する。 Furthermore, when the focal lengths of the eyepiece lens systems 2a and 2b are adjusted to the predetermined positions described below, a stereoscopic effect is obtained in which a region that is in focus is wide regardless of a low-cost convex lens.

更に、立体視ビュア基体を頭部装着手段で頭部に装着すると両手を自由に使用できる効果を奏する。 Further, when the stereoscopic viewer base is mounted on the head by the head mounting means, there is an effect that both hands can be used freely.

Since the connecting line (valley fold line) 23 (the adhesive margin 6 is pasted on the see-through part 11) between the see-through part 11 and the upper connecting part 13. Connecting lines (valley fold lines) 24a and 24b where the see-through part 11 and the lower connecting part 15 contact each other are convex curves with the see-through part 11 as a base point.
The connecting line (valley fold line) 25 where the image holding unit 12 and the upper connecting part 14 are in contact with each other, and the connecting line (valley fold line) 26 where the image holding unit 12 and the lower connecting part 16 are in contact with each other, respectively. It is a concave curve with a base point. In the following description, “valley fold” means bending in which the inside of the stereoscopic viewer 1 is concave. The glue margin 6 is bonded to the see-through portion 11 so that the broken line 23b is folded in a valley and overlaps the connecting line 23. The connecting lines (valley fold lines) 24a and 24b are formed in a concave curve with the see-through portion 11 as a base point, and the see-through portion 11 has a curved surface that curves convexly toward the viewer.

図３は立体視ビュア第１実施例を折畳んだ状態で、透視部１１を丁度図２の裏側から見ている。上部連接部１３と上部連接部１４とが接する連接線２１ａ、２１ｂ及び、下部連接部１５と下部連接部１６とが接する連接線２２は図３に示すようにそれぞれ谷折りして立体視ビュア１を平坦に折畳む。
立体視ビュア実施例１を使用するときは、前記連接線２１ａ、２１ｂをそれぞれ両手の人差し指で、前記連接線２２を両手の親指で挟むように押えて図１で示した状態にする。折線２３、２４、２５、２６が曲線であるので、観察時に前記透視部１１および前記画像保持部１２が観察者側を基点にして凹状の２次曲面に成って相対面する。前記透視部１１および前記画像保持部１２のそれぞれの上部を前記上部連接部１３、１４で、それぞれの下部を前記下部連接部１５、１６で連接して立体視ビュア全体が強固で安定した立体的形状となると共に、前記接眼レンズ系２ａ、２ｂの焦点位置を所定の位置に保持する。透視部１１に設られた接眼レンズ系２ａ、２ｂを透視して、相対面する画像保持部１２上の立体視用画像３ａ、３ｂを観賞する。材質は紙、樹脂等のシート材が適しているが、これに限定されるものではない。更に、立体視用画像３ａ、３ｂは画像保持部１２の曲面に合わせて幾何補正をすると立体視効果が増すことができる。なお、本出願書類に記された立体視用画像は湾曲するフレキシブルディスプレイに表示した画像でも良い。FIG. 3 is a perspective view of the fluoroscopic part 11 seen from the back side of FIG. 2 in a state in which the first embodiment of the stereoscopic viewer is folded. As shown in FIG. 3, the connecting lines 21a and 21b where the upper connecting part 13 and the upper connecting part 14 are in contact and the connecting lines 22 where the lower connecting part 15 and the lower connecting part 16 are contacted are valley-folded as shown in FIG. Fold it flat.
When the stereoscopic viewer embodiment 1 is used, the connecting lines 21a and 21b are pressed with the index fingers of both hands, and the connecting line 22 is pressed with the thumbs of both hands to the state shown in FIG. Since the fold lines 23, 24, 25, and 26 are curved, the fluoroscopic part 11 and the image holding part 12 are opposed to each other as a concave quadratic curved surface starting from the observer side during observation. The upper part of each of the fluoroscopic part 11 and the image holding part 12 is connected to the upper connecting parts 13 and 14 and the lower part thereof is connected to the lower connecting parts 15 and 16 so that the entire stereoscopic viewer is strong and stable. In addition to the shape, the focal positions of the eyepiece lens systems 2a and 2b are held at predetermined positions. The eyepiece lens systems 2a and 2b provided in the see-through unit 11 are seen through and the stereoscopic images 3a and 3b on the image holding unit 12 facing each other are viewed. The material is suitably a sheet material such as paper or resin, but is not limited thereto. Further, if the stereoscopic images 3a and 3b are geometrically corrected according to the curved surface of the image holding unit 12, the stereoscopic effect can be increased. Note that the stereoscopic image described in the present application document may be an image displayed on a curved flexible display.

図４は実施例１の変形例である。接眼レンズ系２ａの位置で切った断面図である。図１で示した前記も画像保持部１２の観察者側に、開口された画像保持部額縁９が隙間をあけて接着されている。前記隙間には取り替え可能な立体視用画像カード８（図９に斜視図で示されている）を差し込むことができる。観察者は透視部１１上の接眼レンズ２ａを透視して、画像保持部額縁９の開口部越しに立体視画像３ａを観賞する。本実施例１変形例は画像保持部１２に立体視用画像カード８を挿入して保持する画像保持部額縁９とそれで形成された隙間を備えた立体視ビュアである。 FIG. 4 shows a modification of the first embodiment. It is sectional drawing cut in the position of the eyepiece lens system 2a. The opened image holding unit frame 9 is adhered to the observer side of the image holding unit 12 with a gap. A replaceable stereoscopic image card 8 (shown in a perspective view in FIG. 9) can be inserted into the gap. The observer sees through the eyepiece lens 2 a on the see-through unit 11 and views the stereoscopic image 3 a through the opening of the image holding unit frame 9. The modification of the first embodiment is a stereoscopic viewer provided with an image holding unit frame 9 for inserting and holding the stereoscopic image card 8 in the image holding unit 12 and a gap formed thereby.

図５は本発明の実施例２の形態に係わる立体視ビュアを示している斜視図である。立体視ビュア第２実施例は図１で説明した立体視ビュア第１実施例の収納時に折畳む手段である折線を折った状態に常時固定にした構成である。従って、観察者側に常に湾曲した前記透視部１１と前記画像保持部１２とが相対面するように、上部を上部連接部１３下部を下部連接部１５で連接し、上部連接部１３には採光窓５が設けられている構成である。上部連接部１３は上部連接部１４を含んで一体になり、下部連接部１５は下部連接部１６を含んで一体になっている。第１実施例のような折畳み式の利便性は失われるが、樹脂等で一体で製造して、より強靭な立体視ビュア基体を構成できる。折畳んで平坦にする必要がないので前記画像保持部１２の上辺または下辺の少なくとも一方は前記画像保持部１２の垂直方向にくびれた曲線でなくても良いが、ただし前記画像保持部１２は観察者側に湾曲した曲面である。 FIG. 5 is a perspective view showing a stereoscopic viewer according to the embodiment 2 of the present invention. The second embodiment of the stereoscopic viewer has a configuration in which a fold line, which is a means for folding at the time of storage of the first embodiment of the stereoscopic viewer described in FIG. Therefore, the upper connecting part 13 is connected to the lower connecting part 15 with the lower connecting part 15 so that the fluoroscopic part 11 and the image holding part 12 which are always curved toward the viewer face each other, and the upper connecting part 13 is light-collected. In this configuration, a window 5 is provided. The upper connecting portion 13 is integrated including the upper connecting portion 14, and the lower connecting portion 15 is integrated including the lower connecting portion 16. Although the convenience of the folding type as in the first embodiment is lost, it is possible to construct a tougher stereoscopic viewer base by integrally manufacturing with a resin or the like. Since it is not necessary to fold and flatten, at least one of the upper side or the lower side of the image holding unit 12 may not be a curved line constricted in the vertical direction of the image holding unit 12. It is a curved surface curved toward the person.

実施例２の変形例について説明する。図５に示した掛止部１０は実施例２の変形例に備わった部材で、頭に装着するときに耳に掛けるつるである。掛止部１０はベルトや帽子などの頭部に装着する装置でも良い。手で持たなくても立体視が観賞できる効果がある。このとき本発明の立体視ビュアが強固な構造であることが必須となる。第１実施例の折畳式の立体視ビュアに備えても良い。本発明の他の態様の立体視ビュアに頭部装着手段を備えることで頭部に装着することでヘッドマウントディスプレイになる。 A modification of the second embodiment will be described. The latching portion 10 shown in FIG. 5 is a member provided in the modification of the second embodiment, and is a hook that is hung on the ear when worn on the head. The hooking portion 10 may be a device attached to a head such as a belt or a hat. Even if you do not hold it by hand, you can enjoy stereoscopic viewing.

The stereoscopic viewer shown in the perspective view of FIG. 6 is curved toward the observer side to which eyepiece systems 2a and 2b (two convex lenses) having a predetermined focal length similar to those described in FIG. 1 are attached. The lower part is connected by lower connecting parts 15 and 16 so that the see-through part 11 and the image holding part 12 curved to the viewer side on which the stereoscopic images 3a and 3b are printed or pasted face each other. In order to connect the fluoroscopic part 11 and the image holding part 12 and maintain the mutual arrangement relationship, the left side connecting parts 17a and 17b are connected to the left side 29a of the fluoroscopic part 11 and the left side 27a of the image holding part 12. The right side connecting portions 18 a and 18 b are held in the gap between the right side 29 b of the fluoroscopic part 11 and the right side 27 b of the image holding part 12. The see-through part 11 and the lower connecting part 15 are provided with a nose window 4 through which an observer can enter the nose when viewing. In addition, a see-through portion bending holding portion 7 is connected to an upper portion of the see-through portion 11 so that the see-through portion 11 is bent at the time of observation so that the see-through portion 11 is bent with a concave shape on the viewer side.

図７は実施例３の立体視ビュア第３実施例の内側を見ている展開図で、透視部１１と透視部湾曲保持部７との連接線（谷折り線）２８と、透視部１１と下部連接部１５とが接する連接線（谷折り線）２４ａ、２４ｂとは、それぞれ透視部１１を基点として凸状の曲線である。画像保持部１２と下部連接部１６とが接する連接線（谷折り線）２６は画像保持部１２を基点として凹状の曲線である。なお、図６に示した左側面連接部１７ｂに連接した糊代１７ｃは左側面連接部１７ａの内側に接着し、右側面連接部１８ｂに連接した糊代１８ｃは左側面連接部１８ａの内側に接着する。 FIG. 7 is an exploded view of the third embodiment of the stereoscopic viewer according to the third embodiment. The connecting line (valley fold line) 28 between the see-through portion 11 and the see-through portion curve holding portion 7, and the see-through portion 11 The connecting lines (valley fold lines) 24a and 24b that are in contact with the lower connecting part 15 are convex curves with the perspective part 11 as a base point. A connecting line (valley fold line) 26 where the image holding unit 12 and the lower connecting unit 16 are in contact is a concave curve with the image holding unit 12 as a base point. The glue margin 17c connected to the left side connecting portion 17b shown in FIG. 6 is adhered to the inside of the left side connecting portion 17a, and the adhesive margin 18c connected to the right side connecting portion 18b is provided inside the left side connecting portion 18a. Glue.

図８で示すようにビュア収納時には前記左側面連接部１７ａ、１７ｂの中間と右側面連接部１８ａ、１８ｂの中間とで、それぞれ内方に二つ折りされ、下部連接部１５と下部連接部１６とが接する連接線２２は図８に示すように谷折りして平坦に折畳む。
立体視ビュア第３実施例を使用するときは、図６で示すように二つ折りされた前記左側面連接部１７ａ、１７ｂと右側面連接部１８ａ、１８ｂとを両手の人差し指で開き、谷折り状の前記連接線２２を両手の親指で押し上げて、前記左側面連接部１７ａ、１７ｂと右側面連接部１８ａ、１８ｂとの間に配置することで透視部１１上の接眼レンズ系２ａ、２ｂと画像保持部１２上の立体視用画像３ａ、３ｂとの間隔を保持でき、レンズの焦点位置を所定の位置に保持することができる。折線２８、２４ａ、２４ｂが透視部１１を基点として凸状曲線で、折線２６が画像保持部１２を基点として凹状の曲線であるので、観察時に立体視ビュア実施例３を図６の状態にしたときに透視部１１および画像保持部１２が観察者側に湾曲した２次曲面に成り、本実施例の立体視ビュア全体が強固で安定した立体的形状となる。この状態で透視部１１に設られた接眼レンズ系２ａ、２ｂを透視して、相対面する画像保持部１２上の立体視用画像３ａ、３ｂを観賞する。
更に、立体視用画像３ａ、３ｂは画像保持部１２の曲面に合わせて幾何補正をすると立体視効果が増すことができる。As shown in FIG. 8, when the viewer is housed, the middle of the left side connecting parts 17a and 17b and the middle of the right side connecting parts 18a and 18b are folded inward, respectively, and the lower connecting part 15 and the lower connecting part 16 are As shown in FIG. 8, the connecting line 22 in contact with the valley is folded in a valley and folded flat.
When the third embodiment of the stereoscopic viewer is used, the left side connecting parts 17a and 17b and the right side connecting parts 18a and 18b folded in half as shown in FIG. The connecting line 22 is pushed up with the thumbs of both hands, and is placed between the left side connecting parts 17a, 17b and the right side connecting parts 18a, 18b, so that the eyepiece lens systems 2a, 2b on the fluoroscopic part 11 and the image are arranged. The distance from the stereoscopic images 3a and 3b on the holding unit 12 can be held, and the focal position of the lens can be held at a predetermined position. Since the fold lines 28, 24a, and 24b are convex curves with the perspective portion 11 as a base point, and the fold lines 26 are concave curves with the image holding portion 12 as a base point, the stereoscopic viewer Example 3 is in the state of FIG. Sometimes the fluoroscopic part 11 and the image holding part 12 become a quadratic curved surface that is curved toward the viewer, and the entire stereoscopic viewer of this embodiment has a strong and stable three-dimensional shape. In this state, the stereoscopic images 3a and 3b on the image holding unit 12 facing each other are viewed through the eyepiece lens systems 2a and 2b provided in the fluoroscopic unit 11.
Further, if the stereoscopic images 3a and 3b are geometrically corrected according to the curved surface of the image holding unit 12, the stereoscopic effect can be increased.

図９は実施例３の変形例を示す。実施例３の立体視ビュアの画像保持部１２上の立体視用画像３ａ、３ｂは印刷あるいは貼着されているが一種類の立体視しか観賞できない。そこで立体視用画像カード８を別に用意して、湾曲した画像保持部１２にはめ込むように挿入する。このとき前記立体視用画像カード８は湾曲して左側面連接部１７ｂと右側面連接部１８ｂとの間に挟まるが、平面に戻ろうとする反力で前記左側面連接部１７ｂと前記右側面連接部１８ｂを押すことで安定して固定する。前記立体視用画像カード８の下部は中心が凹んでいるので更に安定して収まる。その上、前記左側面連接部１７ｂと前記右側面連接部１８ｂとにコの字型の切り込みを縦に入れてコの字型の画像挟持部２０ａ、２０ｂを内方に折り曲げて前記カード８が飛び出さないように押える。前記立体視用画像カード８は立体視ビュアに装着する前は平面であるが装着後には湾曲する。前記立体視用画像カード８を立体視ビュアと別に補充用カードとして用意することで１つのビュアで多数の立体視画像を観賞できる利点がある。前記立体視用画像カード８の下部の凹みは既存の製品のカードが殆ど矩形であったので差別化する効果もある。本立体視ビュア専用とすることで、規格の異なる立体視画像を誤って見ることによって発生する眼への悪影響を未然に防止することが可能となる。図４で示した前記立体視用画像カード８も同様である。 FIG. 9 shows a modification of the third embodiment. Although the stereoscopic images 3a and 3b on the stereoscopic viewer image holding unit 12 of the third embodiment are printed or pasted, only one type of stereoscopic vision can be viewed. Accordingly, the stereoscopic image card 8 is prepared separately and inserted so as to fit into the curved image holding unit 12. At this time, the stereoscopic image card 8 is curved and is sandwiched between the left side connecting portion 17b and the right side connecting portion 18b, but the left side connecting portion 17b and the right side connecting portion are caused by a reaction force to return to the plane. It is stably fixed by pushing the part 18b. Since the center of the lower portion of the stereoscopic image card 8 is recessed, the image card 8 is more stably stored. In addition, a U-shaped notch is vertically inserted into the left side connecting portion 17b and the right side connecting portion 18b, and the U-shaped image sandwiching portions 20a, 20b are folded inward to form the card 8. Hold it so that it doesn't pop out. The stereoscopic image card 8 is flat before being attached to the stereoscopic viewer, but is curved after being attached. By preparing the stereoscopic image card 8 as a supplementary card separately from the stereoscopic viewer, there is an advantage that a large number of stereoscopic images can be viewed with one viewer. The depression at the bottom of the stereoscopic image card 8 has an effect of differentiating because the cards of existing products are almost rectangular. By using the stereoscopic viewer exclusively, it is possible to prevent adverse effects on the eyes caused by erroneously viewing stereoscopic images with different standards. The same applies to the stereoscopic image card 8 shown in FIG.

図１０および図１１で本発明の実施例４の形態を説明する。図１で示したように本立体視ビュアは観賞時には立体視用画像３ａ、３ｂが観察者側に湾曲している。このとき平面状態で最適化した立体視画像は幾何学的な歪みが発生する。図１０は幾何補正前である。従って、立体視用画像３ａ、３ｂを湾曲した状態で観察するときに最適に見えるように幾何補正して不自然な歪みの少ない立体視画像に補正する。図１１は幾何補正後の画像３ａｂ、３ｂｂである。なお、幾何補正後の前記画像３ａｂ、３ｂｂを制作する他の方法は、前記画像３ａ、３ｂをそれぞれの観察視点位置より観察時の前記画像保持部１２に投影する処理をすることで制作できる。このとき接眼レンズ系２ａ、２ｂのレンズ歪みを考慮した補正をするとより更に良い。 Embodiments of the fourth embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 1, in the stereoscopic viewer, the stereoscopic images 3a and 3b are curved toward the viewer when viewed. At this time, geometric distortion occurs in the stereoscopic image optimized in the planar state. FIG. 10 is before geometric correction. Therefore, the stereoscopic images 3a and 3b are corrected to be a stereoscopic image with less unnatural distortion by geometric correction so as to be optimally observed when observing in a curved state. FIG. 11 shows images 3ab and 3bb after geometric correction. In addition, another method for producing the images 3ab and 3bb after geometric correction can be produced by performing a process of projecting the images 3a and 3b on the image holding unit 12 at the time of observation from the respective observation viewpoint positions. At this time, it is better to perform correction in consideration of lens distortion of the eyepiece lens systems 2a and 2b.

図１２で本発明の実施例５の光学系を説明する。記号Ａは立体視画像の横幅である。点３０ａは立体視画像３ａの左端部、点３１ａは前記画像３ａの中心、点３２ａは前記画像３ａの右端部、点３３ａは前記画像３ａの左端部より１／４の位置にある点、点３４ａは前記画像３ａの右端部より１／４の位置にある点である。同様に、点３０ｂは立体視画像３ｂの左端部、点３１ｂは前記画像３ｂの中心、点３２ｂは前記画像３ｂの右端部、点３３ｂは前記画像３ｂの左端部より１／４の位置にある点、点３４ｂは前記画像３ｂの右端部より１／４の位置にある点である。
立体視観賞では左眼と右眼では対応する点をそれぞれ同時に見て立体視する。すなわち、左眼で前記画像３ａ上の点３０ａを見るとき右眼は画像３ｂ上の点３０ｂ近傍に在る対応点を見る。左眼で前記画像３ａ上の点３２ａを見るとき右眼は画像３ｂ上の点３２ｂ近傍に在る対応点を見る。
本発明の立体視ビュアは観賞時に前記画像３ａおよび前記画像３ｂが湾曲して斜めになり、観察画像の奧行き方向に距離差が発生するのが特徴である。実施例１、実施例２および実施例３の説明で立体視ビュアの接眼レンズ系２ａ、２ｂ（２枚の凸レンズ）が所定の焦点距離を有すると記したが、奥行き方向に距離差がある画像を見る場合、焦点距離を合わせる位置は常識的には図１１で示した画像３ａの中心部に焦点を合わせたＬ１の値である。
前記画像３ａ上の点３１ａおよび前記画像３ｂ上の点３１ｂに接眼レンズ系２ａ、２ｂの焦点距離を合わせると、左眼で点３１ａ近傍と右眼で点３１ｂ近傍との対応点をそれぞれの眼で見る立体視観賞時では立体像にピントが合って見える。左眼で点３０ａ近傍と右眼で点３０ｂ近傍との対応点を立体視するときは双方のピントが双方ボケて見えるので立体像はボケて見える。左眼で点３２ａ近傍と右眼で点３２ｂ近傍の対応点を見て立体視するときは双方のピントがボケて見えるので立体像はボケて見える。従って、画像の中心部のみにピントが合った左右両端がボケた立体像となる。安価な焦点距離の小さい球面凸レンズでは特にこの傾向が強い。このような弊害現象が起こるので、今まで単凸レンズを備えた安価な立体視ビュアは立体視画像に奥行き方向の距離差を付けなかった。An optical system according to Example 5 of the present invention will be described with reference to FIG. Symbol A is the width of the stereoscopic image. The point 30a is the left end of the stereoscopic image 3a, the point 31a is the center of the image 3a, the point 32a is the right end of the image 3a, and the point 33a is a point that is 1/4 of the left end of the image 3a. Reference numeral 34a denotes a point at a position 1/4 from the right end of the image 3a. Similarly, the point 30b is at the left end of the stereoscopic image 3b, the point 31b is at the center of the image 3b, the point 32b is at the right end of the image 3b, and the point 33b is at a position 1/4 from the left end of the image 3b. The point 34b is a point at a position 1/4 from the right end of the image 3b.
In the stereoscopic viewing, the left eye and the right eye see the corresponding points at the same time and perform stereoscopic viewing. That is, when the point 30a on the image 3a is viewed with the left eye, the right eye sees a corresponding point in the vicinity of the point 30b on the image 3b. When the left eye sees the point 32a on the image 3a, the right eye sees a corresponding point in the vicinity of the point 32b on the image 3b.
The stereoscopic viewer of the present invention is characterized in that the image 3a and the image 3b are curved and slanted during viewing, and a distance difference occurs in the direction of the observed image. In the description of the first, second, and third embodiments, it is described that the eyepiece systems 2a and 2b (two convex lenses) of the stereoscopic viewer have a predetermined focal length, but there is a distance difference in the depth direction. , The position at which the focal length is adjusted is commonly the value of L1 focused on the center of the image 3a shown in FIG.
When the focal lengths of the eyepiece systems 2a and 2b are matched with the point 31a on the image 3a and the point 31b on the image 3b, the corresponding points between the point 31a near the left eye and the point 31b near the right eye The stereoscopic image looks out of focus when viewing in 3D. When the corresponding point between the point 30a near the left eye and the point 30b near the right eye is stereoscopically viewed, the two images are both out of focus, so the stereoscopic image appears blurred. When viewing the corresponding point near the point 32a with the left eye and the corresponding point near the point 32b with the right eye, the stereoscopic image appears blurred because both of the focal points appear blurred. Accordingly, the left and right ends of the image are in focus only at the center of the image, resulting in a blurred stereoscopic image. This tendency is particularly strong in a spherical convex lens with a small focal length. Due to this adverse phenomenon, an inexpensive stereoscopic viewer equipped with a single convex lens has not provided a distance difference in the depth direction to a stereoscopic image.

しかし、立体視では一対の立体視画像の一方の画像にピントが合い、他方の画像がボケている場合、立体視観賞時に立体像にピントが合って見えることが知られている。
立体視用画像３ａ、３ｂ上のそれぞれの点３３ａ、３３ｂに接眼光学系２ａ、２ｂの焦点距離を合わせると、左眼で点３０ａ近傍と右眼で点３０ｂ近傍の対応点を立体視するときは点３０ａ近傍ではピントが比較的合って見えるが、右眼で見る点３０ｂ近傍ではボケて見える。従って立体視観賞時には、上記理由でピントが比較的合った立体像が見える。また、左眼で点３２ａ近傍と右眼で点３２ｂ近傍の対応点を立体視するときは、点３２ａ近傍ではピントがボケて見えるが、右眼で見る点３２ｂ近傍ではがピントが比較的合って見える。従って立体視観賞時には上記理由でピントが比較的合った立体像が見える。
左接眼レンズ系２ａは前記画像３ａの左端部から中心の位置までの間に、右接眼レンズ系２ｂは前記画像３ｂの右端部から中心の位置までの間心に焦点距離を合わせる。より好ましくは立体視用画像３ａ、３ｂのそれぞれの外側から１／４の位置に在る点３３ａ、点３４ｂ（Ｌ２の距離）近傍に前記接眼レンズ系２ａ、２ｂの焦点距離を合わせると、立体視観賞時にピントが合って見える領域が広くなり、立体像が広く感じられる効果がある。
同様に、前記左接眼レンズ系２ａは前記画像３ａの右端部から中心の位置までの間に、前記右接眼レンズ系２ｂは前記画像３ｂの右端部から中心の位置までの間に焦点距離を合わせる。より好ましくは立体視用画像３ａ、３ｂのそれぞれの内側から１／４の位置に在る点３４ａ、点３３ｂ（Ｌ３の距離）近傍に前記接眼レンズ系２ａ、２ｂの焦点距離を合わせると、立体視観賞時にピントが合って見える領域が広くなり、立体像が広く感じられる効果がある。安価な球面単凸レンズでは特にこの作用・効果が有効に働く。However, it is known that in stereoscopic viewing, when one image of a pair of stereoscopic images is in focus and the other image is blurred, the stereoscopic image appears to be in focus during stereoscopic viewing.
When the focal lengths of the eyepiece optical systems 2a and 2b are adjusted to the respective points 33a and 33b on the stereoscopic images 3a and 3b, when corresponding points near the point 30a with the left eye and the point 30b near with the right eye are stereoscopically viewed. Appears to be relatively in focus near the point 30a, but appears blurred near the point 30b viewed with the right eye. Accordingly, during stereoscopic viewing, a stereoscopic image that is relatively in focus for the above reason can be seen. When the corresponding points near the point 32a and the right eye near the point 32b are stereoscopically viewed with the left eye, the focus appears to be blurred near the point 32a, but the focus is relatively close to the point 32b viewed with the right eye. Looks. Accordingly, when viewing stereoscopically, a stereoscopic image that is relatively in focus for the above reason can be seen.
The left eyepiece lens system 2a adjusts the focal length from the left end of the image 3a to the center position, and the right eyepiece lens system 2b adjusts the focal length from the right end of the image 3b to the center position. More preferably, when the focal lengths of the eyepiece lens systems 2a and 2b are adjusted in the vicinity of the points 33a and 34b (distance L2) which are located at 1/4 positions from the outside of the stereoscopic images 3a and 3b, respectively, There is an effect that the area that is in focus at the time of viewing is widened, and a stereoscopic image is widely felt.
Similarly, the left eyepiece lens system 2a adjusts the focal length between the right end portion and the center position of the image 3a, and the right eyepiece lens system 2b adjusts the focal length between the right end portion of the image 3b and the center position. . More preferably, when the focal lengths of the eyepiece lens systems 2a and 2b are adjusted in the vicinity of the point 34a and the point 33b (distance L3) which are ¼ positions from the inside of the stereoscopic images 3a and 3b, respectively, There is an effect that the area that is in focus at the time of viewing is widened, and a stereoscopic image is widely felt. This action / effect works particularly effectively with an inexpensive spherical single convex lens.
