Japanese Patent Laid-Open No. 10-148996 JP 2005-257901 A

然しながら、上述立体表示装置においては、左目用及び右目用の偏光板を有する眼鏡を着用する必要があり、この立体表示装置を展示場、博物館等で使用し、見学者に表示、説明等する場合には、この左目用及び右目用の偏光板を有する眼鏡を多数用意し、配布、回収する必要がある。   However, in the above-mentioned stereoscopic display device, it is necessary to wear glasses having polarizing plates for the left eye and right eye. When this stereoscopic display device is used in an exhibition hall, a museum, etc., it is displayed and explained to a visitor. It is necessary to prepare, distribute and collect a large number of glasses having polarizing plates for the left eye and right eye.

この左目用及び右目用の偏光板を有する眼鏡を配布、回収するようにしたときには、配布、回収する人員が必要である不都合があると共にこの眼鏡を配布、回収する入退場時に混雑する不都合があった。   Distributing and collecting glasses with left-eye and right-eye polarizers has the disadvantage of requiring personnel to distribute and collect, as well as the inconvenience of crowding when entering and leaving the glasses. It was.

更に、この左目用及び右目用の偏光板を有する眼鏡を多数用意する必要があると共に定期的に洗浄する必要があり、維持費等費用が掛かる不都合があった。   In addition, it is necessary to prepare a large number of glasses having polarizing plates for the left eye and right eye, and it is necessary to periodically clean the glasses.

本発明は、斯かる点に鑑み、左目用及び右目用の偏光板を有する眼鏡を着用することなく立体表示画面を見ることができるようにすることを目的とする。   In view of the above, an object of the present invention is to make it possible to view a stereoscopic display screen without wearing glasses having polarizing plates for left and right eyes.

本発明立体表示装置は、左目用及び右目用の偏光特性の異なった映像画面が得られる立体表示画面に対向した所定位置に仕切り板を設け、この仕切り板に左目用及び右目用の偏光板を配して覗き窓とし、この覗き窓を通してこの立体表示画面を見るようにしたものである。   The stereoscopic display device of the present invention is provided with a partition plate at a predetermined position facing a stereoscopic display screen from which video images having different polarization characteristics for left eye and right eye are obtained, and polarizing plates for left eye and right eye are provided on the partition plate. The three-dimensional display screen is viewed through the viewing window.

本発明によれば、立体表示画面に対向した所定位置に仕切り板を設け、この仕切り板に左目用及び右目用の偏光板を配して覗き窓とし、この覗き窓を通してこの立体表示画面を見るようにしたので、左目用及び右目用の偏光板を有する眼鏡を着用することなく立体表示画面を見ることができる。   According to the present invention, a partition plate is provided at a predetermined position facing the stereoscopic display screen, and a polarizing plate for the left eye and the right eye is provided on the partition plate to form a viewing window, and the stereoscopic display screen is viewed through the viewing window. As a result, the stereoscopic display screen can be viewed without wearing glasses having polarizing plates for the left eye and the right eye.

本発明によれば、左目用及び右目用の偏光板を有する眼鏡を配布、回収しないので、この眼鏡を配布、回収する人員が要らないと共にこの眼鏡を配布、回収する必要がないので入退の流れがスムーズになる。   According to the present invention, the glasses having the polarizing plates for the left eye and the right eye are not distributed and collected, so there is no need to distribute and collect these glasses, and there is no need to distribute and collect these glasses. The flow becomes smooth.

また、左目用及び右目用の偏光板を配した仕切り板は、眼鏡のように手で持つことがないので、汚れ難く、維持が容易である。   Moreover, since the partition plate provided with the polarizing plates for the left eye and the right eye is not held by hand like eyeglasses, it is difficult to get dirty and is easy to maintain.

以下、図1、図2、図3を参照して、本発明立体表示装置を実施するための最良の形態の例につき説明する。   Hereinafter, an example of the best mode for carrying out the stereoscopic display device of the present invention will be described with reference to FIG. 1, FIG. 2, and FIG.

図1において、1は周知の立体映像投射装置であり、2は、この立体映像投射装置1よりの左目用及び右目用の偏光特性の異なった映像画面が投写される例えば80インチのスクリーンを示す。   In FIG. 1, reference numeral 1 denotes a known stereoscopic video projection apparatus, and reference numeral 2 denotes, for example, an 80-inch screen on which video screens having different left-eye and right-eye polarization characteristics are projected from the stereoscopic video projection apparatus 1. .

この立体映像投射装置1は、図3に示す如く、左目用液晶プロジェクタ1Sと右目用液晶プロジェクタ1Pとを水平方向に夫々光軸5が互いに平行に成るように上下に配し、右目用液晶プロジェクタ1Pの映像をハーフミラー3を透過してスクリーン2に投射する。   As shown in FIG. 3, this stereoscopic image projection apparatus 1 has a left-eye liquid crystal projector 1S and a right-eye liquid crystal projector 1P arranged vertically so that their optical axes 5 are parallel to each other in the horizontal direction. The 1P image is transmitted through the half mirror 3 and projected onto the screen 2.

一方、左目用液晶プロジェクタ1Sの映像は、表面鏡6とハーフミラー3とで反射されてスクリーン2に投射する如くする。ここで、表面鏡6とハーフミラー3とは互いに平行で、且つ右目用液晶プロジェクタ1Pの光軸及び左目用液晶プロジェクタ1Sの光軸に45度をなすように配置する。   On the other hand, the image of the left-eye liquid crystal projector 1S is reflected by the surface mirror 6 and the half mirror 3 and projected onto the screen 2. Here, the surface mirror 6 and the half mirror 3 are arranged parallel to each other and at an angle of 45 degrees to the optical axis of the right-eye liquid crystal projector 1P and the optical axis of the left-eye liquid crystal projector 1S.

更に、左目用液晶プロジェクタ1Sの投射レンズには、出射光がS波となるよう偏光面を回転するフィルタ4Sを装着しており、また、右目用液晶プロジェクタ1Pの投射レンズには、出射光がP波となるよう偏光面を回転するフィルタ4Pを装着する。   Furthermore, the projection lens of the left-eye liquid crystal projector 1S is equipped with a filter 4S that rotates the polarization plane so that the outgoing light becomes S waves, and the outgoing light is supplied to the projection lens of the right-eye liquid crystal projector 1P. A filter 4P that rotates the polarization plane so as to be a P wave is attached.

この場合、左目用液晶プロジェクタ1Sと右目用液晶プロジェクタ1Pとの光軸を一致させ、また夫々の光路長も等しくすることで、左目用映像結像面(左目用映像画面)と右目用映像結像面(右目用映像画面)とがスクリーン2上の同一平面内に納まり、左右目に視差角に依存する画面の差を残し画面が重なる。例えば図1に示す如く、スクリーン2上にこの立体映像投射装置1よりの立体表示画面を得ることができる。   In this case, by aligning the optical axes of the left-eye liquid crystal projector 1S and the right-eye liquid crystal projector 1P and making the optical path lengths equal to each other, the left-eye image formation surface (left-eye image screen) and the right-eye image connection are displayed. The image plane (right-eye video screen) fits in the same plane on the screen 2, and the left and right eyes overlap with the screen difference depending on the parallax angle. For example, as shown in FIG. 1, a stereoscopic display screen from the stereoscopic video projector 1 can be obtained on the screen 2.

本例においては、図1、図2に示す如く、この立体表示画面の得られるスクリーン2に対向した所定位置にこのスクリーン2上の左目用映像画面及び右目用映像画面を夫々見ることができる左目用の偏光板11L及び右目用の偏光板11Rの対が垂直方向のインライン状に複数個配し、複数個の覗き窓11、11、11…とした板状の壁(仕切り板)10を設ける。   In this example, as shown in FIGS. 1 and 2, the left-eye video screen and the left-eye video screen on the screen 2 can be viewed at predetermined positions facing the screen 2 from which the stereoscopic display screen is obtained. A plurality of pairs of a polarizing plate 11L for the right eye and a polarizing plate 11R for the right eye are arranged in an inline shape in the vertical direction, and a plate-like wall (partition plate) 10 having a plurality of viewing windows 11, 11, 11. .

この場合、この左目用の偏光板11L及び右目用の偏光板11Rは、周知のものを用い、また、この板状の壁(仕切り板)10の内側(スクリーン2側)は、黒色とするを可とする。   In this case, the left-eye polarizing plate 11L and the right-eye polarizing plate 11R are well-known, and the inner side (screen 2 side) of the plate-like wall (partition plate) 10 is black. Yes.

本例においては、この左目用の偏光板11L及び右目用の偏光板11Rの対と対との水平方向の間隔Wを人間の両目の間隔例えば65mm以上とする。この場合、人の左右両目が同時に異なる対の偏光板11L、11Rに対応することがない。   In this example, the horizontal interval W between the pair of the left-eye polarizing plate 11L and the right-eye polarizing plate 11R is set to, for example, 65 mm or more between human eyes. In this case, the left and right eyes of a person do not correspond to different pairs of polarizing plates 11L and 11R at the same time.

本例においては、この板状の壁(仕切り板)10の左目用の偏光板11L及び右目用の偏光板11Rの対が垂直方向のインライン状に複数個配された、複数個の覗き窓11、11、11…を設けた板状の壁(仕切り板)10の下部の近傍の所定位置に左目用の偏光板11L又は右目用の偏光板11Rだけの覗き窓12を設ける。   In this example, a plurality of viewing windows 11 in which a plurality of pairs of left-eye polarizing plates 11L and right-eye polarizing plates 11R of the plate-like wall (partition plate) 10 are arranged in an inline shape in the vertical direction. , 11, 11... Are provided at a predetermined position in the vicinity of the lower part of the plate-like wall (partition plate) 10 provided with the left-eye polarizing plate 11L or the right-eye polarizing plate 11R.

本例は、上述の如く構成されているので、観察者が観察者の左目及び右目を夫々板状の壁(仕切り板)10の左目用の偏光板11L及び右目用の偏光板11Rに近ずけ、これを通してスクリーン2を見たときには、左目でスクリーン2上の左目用映像画面が見え、右目でスクリーン2上の右目用映像画面が見え、観察者の両目の視差角で立体感のある画像を見ることができる。   Since this example is configured as described above, the observer is not close to the left-eye polarizing plate 11L and the right-eye polarizing plate 11R of the observer's left eye and right eye, respectively, of the plate-like wall (partition plate) 10. Thus, when viewing the screen 2 through this, the left eye can see the left-eye video screen on the screen 2, the right eye can see the right-eye video screen on the screen 2, and the viewer has a stereoscopic image with the parallax angles of both eyes Can see.

また、この観察者が、この板状の壁(仕切り板)10の下部の近傍の所定位置に左目用の偏光板11L又は右目用の偏光板11Rだけの覗き窓12より、このスクリーン2を見たときには、2次元の左目用映像画面又は右目用映像画面を鮮明に見ることができる。   In addition, the observer views the screen 2 from a viewing window 12 having only the polarizing plate 11L for the left eye or the polarizing plate 11R for the right eye at a predetermined position near the lower portion of the plate-like wall (partition plate) 10. The two-dimensional left-eye video screen or right-eye video screen can be clearly seen.

また、観察者が、比較的遠くより、この板状の壁(仕切り板)10の複数個の覗き窓11、11、11…を通してこのスクリーン2を見たときには、左目用の偏光板11L又は右目用の偏光板11Rを通してこのスクリーン2を見ることとなるので、2次元の鮮明な画像が見える。因みに左目用の偏光板11L及び右目用の偏光板11Rを通さないで、このスクリーン2を見たときには、左目用映像画面及び右目用映像画面が重畳された画面であり、極めて見にくい画面である。   When the observer views the screen 2 through a plurality of viewing windows 11, 11, 11... Of the plate-like wall (partition plate) 10 from a relatively long distance, the left-eye polarizing plate 11L or the right-eye. Since the screen 2 is viewed through the polarizing plate 11R, a two-dimensional clear image can be seen. Incidentally, when the screen 2 is viewed without passing through the left-eye polarizing plate 11L and the right-eye polarizing plate 11R, the left-eye video screen and the right-eye video screen are superimposed on each other, and are extremely difficult to see.

上述例によれば、スクリーン2上の立体表示画面に対向した所定位置に板状の壁(仕切り板)10を設け、この板状の壁(仕切り板)10に左目用及び右目用の偏光板11L及び11Rを配して覗き窓11とし、この覗き窓11を通してこの立体表示画面を見るようにしたので、左目用及び右目用の偏光板を有する眼鏡を着用することなく立体表示画面を見ることができる。   According to the above-described example, the plate-like wall (partition plate) 10 is provided at a predetermined position facing the stereoscopic display screen on the screen 2, and the left-eye and right-eye polarizing plates are provided on the plate-like wall (partition plate) 10. Since 11L and 11R are arranged as a viewing window 11 and this stereoscopic display screen is viewed through the viewing window 11, the stereoscopic display screen can be viewed without wearing glasses having polarizing plates for the left and right eyes. Can do.

上述例によれば、左目用及び右目用の偏光板を有する眼鏡を配布、回収しないので、この眼鏡を配布、回収する人員が要らないと共にこの眼鏡を配布、回収する必要がないので入退の流れがスムーズになる。   According to the above-described example, the glasses having the polarizing plates for the left eye and the right eye are not distributed and collected, so there is no need to distribute and collect these glasses, and it is not necessary to distribute and collect these glasses. The flow becomes smooth.

また、上述例によれば、左目用及び右目用の偏光板11L及び11Rを配した板状の壁(仕切り板)10は、眼鏡のように手で持つことがないので、汚れ難く、維持が容易である。   Further, according to the above-described example, the plate-like wall (partition plate) 10 provided with the polarizing plates 11L and 11R for the left eye and the right eye is not easily held like a pair of glasses, so it is difficult to be stained and maintained. Easy.

図4は、本発明を実施するための最良の形態の他の例を示す。この図4において、20は立体カラーモニタを示し、この立体カラーモニタ20は、ハーフミラー21の上端部を観察窓22の上部手前に固定すると共にこのハーフミラー21の下端部を、この観察窓22の下部奥に固定し、このハーフミラー21が水平面に対し前面方向に向かって45度面を形成する如くする。   FIG. 4 shows another example of the best mode for carrying out the present invention. In FIG. 4, reference numeral 20 denotes a stereoscopic color monitor. The stereoscopic color monitor 20 fixes the upper end portion of the half mirror 21 in front of the upper portion of the observation window 22 and the lower end portion of the half mirror 21 to the observation window 22. The half mirror 21 forms a 45-degree surface in the front direction with respect to the horizontal plane.

このハーフミラー21の観察窓22側とは、反対側の後方に水平面に対して画面が垂直となる左目用画面を表示する偏光方向が左45度の液晶表示装置23Lを固定する。この場合、この液晶表示装置23Lの上側を観察窓22の上側、この液晶表示装置23Lの下側をこの観察窓22の下側に対応する如くする。   A liquid crystal display device 23L having a polarization direction of 45 degrees to the left for displaying a screen for the left eye whose screen is perpendicular to the horizontal plane is fixed to the rear side opposite to the observation window 22 side of the half mirror 21. In this case, the upper side of the liquid crystal display device 23L corresponds to the upper side of the observation window 22, and the lower side of the liquid crystal display device 23L corresponds to the lower side of the observation window 22.

このハーフミラー21の下側に水平面に対して画面が水平となる右目用画面を表示する偏光方向が左45度の液晶表示装置23Rを固定する。この場合、この液晶表示装置23Rの上側が手前側、この液晶表示装置23Rの下側が奥側に位置する如くする。   A liquid crystal display device 23R having a polarization direction of 45 degrees to the left is fixed below the half mirror 21 so as to display a right-eye screen whose screen is horizontal with respect to a horizontal plane. In this case, the upper side of the liquid crystal display device 23R is positioned on the near side, and the lower side of the liquid crystal display device 23R is positioned on the back side.

また、観察窓22における視軸を左目用画面を表示する液晶表示装置23Lの画面の中心に垂直になるようにすると共に右目用画面を表示する液晶表示装置23Rの画面の中心がこの視軸とこのハーフミラー21で重なるようにしたものである。   Further, the visual axis in the observation window 22 is set to be perpendicular to the center of the screen of the liquid crystal display device 23L that displays the screen for the left eye, and the center of the screen of the liquid crystal display device 23R that displays the screen for the right eye is the visual axis. The half mirror 21 is overlapped.

この立体カラーモニタ20においては、左目位置で被写体を撮像する左目用カメラよりの左目用の映像信号を左目用の液晶表示装置23Lに供給し、この左目用の映像信号を左目用の液晶表示装置23Lで表示する。   In this stereoscopic color monitor 20, the left-eye video signal from the left-eye camera that captures the subject at the left-eye position is supplied to the left-eye liquid crystal display device 23L, and the left-eye video signal is supplied to the left-eye liquid crystal display device. Display in 23L.

一方、右目位置で被写体を撮像する右目用カメラよりの右目用の映像信号を走査方向反転回路を介して右目用の液晶表示装置23Rに供給し、この走査方向反転回路で、その映像の左側と右側とが反転するように処理し、この右目用の映像信号を右目用の液晶表示装置23Rで左右が反転した映像を表示する。   On the other hand, a right-eye video signal from a right-eye camera that captures a subject at the right-eye position is supplied to a right-eye liquid crystal display device 23R via a scanning direction inversion circuit. Processing is performed so that the right side is reversed, and the right-eye video signal is displayed on the right-eye liquid crystal display device 23R.

この場合、左目用の液晶表示装置23Lよりの映像光は左45度直線偏光であり、ハーフミラー21を左45度の状態で通過し、また右目用の液晶表示装置23Rよりの映像光は左45度直線偏光であるがハーフミラー21で反射され右45度直線偏光となる。   In this case, the image light from the left-eye liquid crystal display device 23L is 45-degree linearly polarized light on the left, passes through the half mirror 21 in the left 45-degree state, and the image light from the right-eye liquid crystal display device 23R is left-handed. Although it is 45 degree linearly polarized light, it is reflected by the half mirror 21 and becomes right 45 degree linearly polarized light.

本例においては、図4に示す如く、この立体カラーモニタ20の立体表示画像が得られる観察窓22に対応する前面側の所定位置に観察窓22の左目用映像画面及び右目用映像画面を夫々見ることができる左目用の偏光板11L及び右目用の偏光板11Rの対が垂直方向のインライン状に複数個配し、複数個の覗き窓11、11、11…とした仕切り板10を設ける。   In this example, as shown in FIG. 4, the left-eye video screen and the right-eye video screen of the observation window 22 are respectively displayed at predetermined positions on the front side corresponding to the observation window 22 from which the stereoscopic display image of the stereoscopic color monitor 20 is obtained. A plurality of pairs of a left-eye polarizing plate 11L and a right-eye polarizing plate 11R that can be seen are arranged in an in-line shape in the vertical direction, and a partition plate 10 having a plurality of viewing windows 11, 11, 11,.

この仕切り板10は、例えば図5及び図6に示す如く、複数の対の左目用の偏光板11L及び右目用の偏光板11Rを複数の対のインライン状の窓を有する黒色の合成樹脂より成る2つの枠体30a及び30bに挟んで固定し、その前面側に表面及び裏面に外光の透過率を上げて表面反射を減らすARコートした透明アクリル板31を設けたものである。   For example, as shown in FIGS. 5 and 6, the partition plate 10 includes a plurality of pairs of left-eye polarizing plates 11 </ b> L and a right-eye polarizing plate 11 </ b> R made of black synthetic resin having a plurality of pairs of inline windows. A transparent acrylic plate 31 with an AR coating is provided on the front side and the back side of the frame 30a and 30b.

本例においては、この左目用の偏光板11L及び右目用の偏光板11Rの対と対との水平方向の間隔Wを人間の両目の間隔例えば65mm以上とする。この場合、人の左右両目が同時に異なる対の偏光板11L、11Rに対応することがない。   In this example, the horizontal interval W between the pair of the left-eye polarizing plate 11L and the right-eye polarizing plate 11R is set to, for example, 65 mm or more between human eyes. In this case, the left and right eyes of a person do not correspond to different pairs of polarizing plates 11L and 11R at the same time.

本例は、上述の如く構成されているので、観察者が観察者の左目及び右目を夫々仕切り板10の左目用の偏光板11L及び右目用の偏光板11Rに近ずけ、これを通して観察窓22を見たときには、左目で左目用の液晶表示装置23Lより到来する左45度直線偏光の映像光が見え、右目で右目用の液晶表示装置23Rより到来する右45度直線偏光の映像光が見え、両目の視差で観察者は、立体感を得ることができる。   Since this example is configured as described above, the observer approaches the left eye polarizing plate 11L and the right eye polarizing plate 11R of the partition plate 10 respectively through the observer's left eye and right eye, and through this the observation window 22, the left 45-degree linearly polarized image light coming from the left-eye liquid crystal display device 23 </ b> L is seen by the left eye, and the right 45-degree linearly-polarized video light coming from the right-eye liquid crystal display device 23 </ b> R is seen by the right eye. It can be seen and the observer can obtain a stereoscopic effect with the parallax of both eyes.

斯かる、図4例においても、上述図1例同様の作用効果が得られることは容易に理解できよう。   It can be easily understood that the same operational effects as in FIG. 1 can be obtained in the example of FIG.

尚、上述例では、左目用の偏光板11L及び右目用の偏光板11Rの対が垂直方向のインライン状に複数個配し、複数個の覗き窓11、11、11…とした仕切り板10を設けた例に付き述べたが、この左目用の偏光板11L及び右目用の偏光板11Rの対を図7に示す如く、市松模様に複数個設けると共にこの対と対との水平方向の間隔を人間の両目の間隔よりも大きな間隔で設けるようにしても良い。   In the above-described example, the partition plate 10 having a plurality of pairs of the left-eye polarizing plate 11L and the right-eye polarizing plate 11R arranged in an in-line shape in the vertical direction, and a plurality of viewing windows 11, 11, 11,. As described in the provided example, as shown in FIG. 7, a plurality of pairs of the left-eye polarizing plate 11L and the right-eye polarizing plate 11R are provided in a checkered pattern, and the horizontal distance between the pair and the pair is set. You may make it provide with a space | interval larger than the space | interval of a human both eyes.

また、上述例では、左目用の偏光板11L及び右目用の偏光板11Rの対と対との水平方向の間隔Wを人間の両目の間隔以上に離す如く述べたが、必ずしも、この左目用の偏光板11L及び右目用の偏光板11Rの対と対との水平方向の間隔Wを人間の両目の間隔以上に離す必要はない。この場合、左目用の偏光板11L及び右目用の偏光板11R間に中心マークを付すを可とする。このとき、左目用の偏光板11L及び右目用の偏光板11Rの対の密度を上げた場合には、遠方から、この立体表示画面を見たときの2次元画像に対応する開口率が向上する。   In the above-described example, the horizontal distance W between the pair of the left-eye polarizing plate 11L and the right-eye polarizing plate 11R is described as being more than the distance between both human eyes. It is not necessary that the horizontal interval W between the pair of the polarizing plate 11L and the polarizing plate 11R for the right eye be larger than the interval between the human eyes. In this case, it is possible to place a center mark between the polarizing plate 11L for the left eye and the polarizing plate 11R for the right eye.
