Description

立体視画像表示装置Stereoscopic image display device
　本発明は、右目用画像および左目用画像の２枚の画像を用いて立体視画像を表示する立体視画像表示装置に関するものである。 The present invention relates to a stereoscopic image display device that displays a stereoscopic image using two images, a right-eye image and a left-eye image.
　従来、右目用画像および左目用画像の２枚の画像を組み合わせて表示することにより、視差を利用して立体視できることが知られている。このような立体視できる画像（以下、立体視画像またはステレオ画像という）は、同一の被写体を異なる位置から撮影して取得された互いに視差のある複数の画像に基づいて生成される。 Conventionally, it is known that stereoscopic viewing can be performed using parallax by displaying a combination of two images, a right-eye image and a left-eye image. Such a stereoscopically viewable image (hereinafter referred to as a stereoscopic image or a stereo image) is generated based on a plurality of images having parallax obtained by photographing the same subject from different positions.
　そして、このような立体視画像の生成は、デジタルカメラやテレビなどの分野だけでなく、放射線画像撮影の分野においても利用されている。すなわち、被験者に対して互いに異なる方向から放射線を照射し、その被験者を透過した放射線を放射線画像検出器によりそれぞれ検出して互いに視差のある複数の放射線画像を取得し、これらの放射線画像に基づいて立体視画像を生成することが行われている。そして、このように立体視画像を生成することによって奥行感のある放射線画像を観察することができ、より診断に適した放射線画像を観察することができる。（例えば特許文献１参照） And the generation of such stereoscopic images is used not only in the fields of digital cameras and televisions, but also in the field of radiographic imaging. That is, the subject is irradiated with radiation from different directions, the radiation transmitted through the subject is detected by the radiation image detector, and a plurality of radiation images having parallax are obtained, and based on these radiation images A stereoscopic image is generated. And by generating a stereoscopic image in this way, a radiographic image with a sense of depth can be observed, and a radiographic image more suitable for diagnosis can be observed.

　ところで、上記のような立体視画像を表示するための立体視画像表示装置として、互いに隣接した２つの表示画面とハーフミラーを備え、各表示画面に右目用画像と左目用画像とを各々表示し、ハーフミラーで右目用画像と左目用画像とを立体視画像として見えるように光学的に合成する方式のモニターが提案されている。（例えば特許文献２参照）
　このような互いに隣接する２つの表示画面を備えた表示装置では、立体視画像表示の際に、装置の設置位置やユーザーの観察位置の都合により、２つの表示画面の隣接方向を上下方向または左右方向に変更させたい場合があり得る。 By the way, as a stereoscopic image display apparatus for displaying a stereoscopic image as described above, two adjacent display screens and a half mirror are provided, and a right eye image and a left eye image are displayed on each display screen. In addition, there has been proposed a monitor of a type in which a right-eye image and a left-eye image are optically combined so as to be seen as a stereoscopic image by a half mirror. (For example, see Patent Document 2)
In such a display device having two display screens adjacent to each other, when displaying a stereoscopic image, the adjacent directions of the two display screens are set to the vertical direction or the left and right directions depending on the installation position of the device and the observation position of the user. You may want to change the direction.
　また、立体視画像表示と通常画像表示とを選択的に表示させる場合、ユーザーによっては、通常画像表示においては視線の高さを変えずに各表示画面を観察できるため、２つの表示画面を左右方向に隣接させた方が好ましかったり、逆に２つの表示画面を上下方向に隣接させた方が好ましい場合もあり得る。 In addition, when displaying stereoscopic image display and normal image display selectively, some users can observe each display screen without changing the line-of-sight height in normal image display. In some cases, it is preferable to make the two adjacent display directions, or on the contrary, it is preferable to make two display screens adjacent to each other in the vertical direction.
　このように、２つの表示画面の隣接方向については上下方向または左右方向に変更可能であることが好ましいため、２つの表示画面からなる本体部をスタンドに回転可能に取り付けて、２つの表示画面の隣接方向を自由に変更できるようにすることが考えられる。 As described above, it is preferable that the adjacent directions of the two display screens can be changed in the vertical direction or the left-right direction. Therefore, the main body unit including the two display screens is rotatably attached to the stand, and the two display screens It is conceivable that the adjacent direction can be freely changed.
　この場合、本体部を構成する２つの表示画面を略同一平面状に展開した場合の幾何学的な中心付近を保持すれば、２つの表示画面の隣接方向を上下方向にさせた状態と左右方向にさせた状態のいずれの状態でもバランスがとれ安定的に保持しやすいが、スタンドの高さや本体部の重量バランスの特性等の問題で本体部の中心付近を保持することができない場合、本体部を安定的に保持させるのが難しいという問題がある。 In this case, if the vicinity of the geometric center when the two display screens constituting the main body are expanded on substantially the same plane is maintained, the state in which the adjacent directions of the two display screens are set in the vertical direction and the horizontal direction In any state, it is easy to maintain a balance and stable, but the main body can not be held near the center of the main body due to problems such as stand height and weight balance characteristics of the main body. There is a problem that it is difficult to stably hold.
　本発明は、上記の事情に鑑み、右目用画像および左目用画像の２枚の画像を用いて立体視画像を表示する立体視画像表示装置において、上記問題を解消したものを提供することを目的とする。 In view of the above circumstances, the present invention aims to provide a stereoscopic image display device that displays a stereoscopic image using two images, a right-eye image and a left-eye image, in which the above-described problems are solved.

　本発明の立体視画像表示装置において、第１の支持位置は、前記隣接方向が上下方向の際の本体部の重心位置とし、第２の支持位置は、前記隣接方向が左右方向の際の本体部の重心位置とすることが好ましい。なお、ここでの「重心位置」とは、幾何学的な重心位置としてもよいし、重量の重心位置としてもよい。 In the stereoscopic image display device of the present invention, the first support position is the center of gravity of the main body when the adjacent direction is the vertical direction, and the second support position is the main body when the adjacent direction is the left-right direction. It is preferable to set the center of gravity of the part. Here, the “center of gravity position” may be a geometric center of gravity position or a center of gravity position of weight.
　また、右目用画像表示手段および／または左目用画像表示手段は、通常画像も表示するものとすることが好ましい。 Further, it is preferable that the right-eye image display means and / or the left-eye image display means also display a normal image.
　この場合は、右目用画像表示手段および左目用画像表示手段に表示する画像が立体視画像であるか通常画像であるかを判断する画像判断手段と、画像判断手段による判断に基づいて、右目用画像表示手段および左目用画像表示手段の隣接方向が上下方向となる状態もしくは左右方向となる状態に、本体部を自動的に回転移動させる移動手段とを備えたものとしてもよい。 In this case, based on the determination by the image determination unit and the image determination unit that determines whether the image displayed on the right-eye image display unit and the left-eye image display unit is a stereoscopic image or a normal image, the right-eye image display unit The image display means and the left-eye image display means may be provided with moving means for automatically rotating the main body in a state where the adjacent direction is the vertical direction or the horizontal direction.

FIG. 9 is a cross-sectional view of the sliding groove of the stereoscopic image display device.
　モニタ９は、右目用画像と左目用画像の２枚の画像を用いた立体視画像および通常画像の両方を表示可能なものであって、図４、９に示すように、右目用画像を表示する右目用画像表示部４０、左目用画像を表示する左目用画像表示部４１、および右目用画像と左目用画像とを立体視画像として見えるように光学的に合成するハーフミラー４２がヒンジ４３により回転自在に連結された本体部と、本体部を回転可能に保持する回転軸４５が取り付けられたスタンド４４とから構成されている。 The monitor 9 can display both a stereoscopic image and a normal image using two images of a right-eye image and a left-eye image, and displays a right-eye image as shown in FIGS. A hinge 43 includes a right-eye image display unit 40, a left-eye image display unit 41 that displays a left-eye image, and a half mirror 42 that optically synthesizes the right-eye image and the left-eye image as a stereoscopic image. It comprises a main body part that is rotatably connected and a stand 44 to which a rotary shaft 45 that rotatably holds the main body part is attached.
　右目用画像表示部４０と左目用画像表示部４１における表示光は互いに直交する偏光となるように構成されている。ユーザーは、右目用画像を観察する右目用偏光レンズと左目用画像を観察する左目用偏光レンズを有する偏光メガネを装着し、左目用画像および右目用画像を左右の目でそれぞれ観察することで立体視画像を観察することができる。 The display light in the right-eye image display unit 40 and the left-eye image display unit 41 is configured to be polarized light orthogonal to each other. The user wears polarizing glasses having a right-eye polarizing lens for observing the right-eye image and a left-eye polarizing lens for observing the left-eye image, and observes the left-eye image and the right-eye image with the left and right eyes, respectively. Visual images can be observed.
　また、図６、７に示すように、左目用画像表示部４１の背面には、回転軸４５を摺動可能に保持する摺動溝５０が設けられている。 Further, as shown in FIGS. 6 and 7, a slide groove 50 that slidably holds the rotating shaft 45 is provided on the back surface of the left-eye image display unit 41.
　この摺動溝５０は、図８に示すように、右目用画像表示部４０および左目用画像表示部４１の隣接方向βが上下方向の際の第１の支持位置５０ａ、隣接方向βが左右方向の際の第２の支持位置５０ｂ、および第１の支持位置５０ａから第２の支持位置５０ｂまでをつなぐ連結部５０ｂからなる。ここで、第１の支持位置５０ａは、隣接方向βが上下方向の際の本体部の重心位置に配され、第２の支持位置５０ｂは隣接方向βが左右方向の際の本体部の重心位置に配されている。 As shown in FIG. 8, the sliding groove 50 includes a first support position 50a when the adjacent direction β of the right-eye image display unit 40 and the left-eye image display unit 41 is the vertical direction, and the adjacent direction β is the horizontal direction. The second support position 50b in this case, and the connecting portion 50b connecting the first support position 50a to the second support position 50b. Here, the first support position 50a is arranged at the gravity center position of the main body when the adjacent direction β is the vertical direction, and the second support position 50b is the gravity center position of the main body when the adjacent direction β is the left-right direction. It is arranged in.
　隣接方向βが上下方向の際の本体部の重心位置は、右目用画像表示部４０の表示面４０ａと左目用画像表示部４１の表示面４１ａとのなす角度αが１８０°未満であるときの幾何学的な重心位置を左目用画像表示部４１の背面に投影した位置であり、角度αが９０°から１２０°程度の際の幾何学的な重心位置を左目用画像表示部４１に投影した位置が好ましく、角度αが１１０°の際の幾何学的な重心位置を左目用画像表示部４１に投影した位置が最も好ましい。 The position of the center of gravity of the main body when the adjacent direction β is the vertical direction is when the angle α formed between the display surface 40a of the right-eye image display unit 40 and the display surface 41a of the left-eye image display unit 41 is less than 180 °. The position of the geometric center of gravity is projected onto the back surface of the left-eye image display unit 41, and the geometric center of gravity position when the angle α is about 90 ° to 120 ° is projected onto the left-eye image display unit 41. The position is preferable, and the position obtained by projecting the geometric gravity center position on the left-eye image display unit 41 when the angle α is 110 ° is most preferable.
　また、第１の支持位置５０ａおよび第２の支持位置５０ｂでは、図９に示すように、回転軸４５の先端に形成された嵌合部４５ａと嵌合するロックピン５１が、左目用画像表示部４１の内側から嵌合するようになっており、これにより、２つの画像表示部の隣接方向βを上下方向にさせた状態もしくは隣接方向βを左右方向にさせた状態で、本体部の位置を固定することができる。なお、ロックピン５１の断面形状を矩形とすれば、本体部の回転も規制することができる。 Further, at the first support position 50a and the second support position 50b, as shown in FIG. 9, the lock pin 51 that is fitted to the fitting portion 45a formed at the tip of the rotating shaft 45 has the left-eye image display. The position of the main body portion is set so that the adjacent direction β of the two image display portions is in the up-down direction or the adjacent direction β is in the left-right direction. Can be fixed. In addition, if the cross-sectional shape of the lock pin 51 is a rectangle, the rotation of the main body can also be restricted.
　このような態様とすることにより、スタンド４４の高さや本体部の重量バランスの特性等の問題で本体部の中心付近を保持することができない場合でも、２つの画像表示部の隣接方向βを上下方向にさせた状態と左右方向にさせた状態とで各々最適な位置に支持位置を配することができ、２つの画像表示部の隣接方向βを上下方向にさせた状態と左右方向にさせた状態のいずれの状態でも重量バランスがとれるため、本体部を安定的に保持することができる。 By adopting such an aspect, even when the vicinity of the center of the main body cannot be held due to problems such as the height of the stand 44 and the weight balance characteristics of the main body, the adjacent direction β of the two image display units is moved up and down. The support position can be arranged at an optimum position in each of the state in which the two image display units are set in the horizontal direction and the state in which the horizontal direction is set in the horizontal direction. Since the weight balance can be achieved in any state, the main body can be stably held.
　このモニタ９において、立体視画像を表示する際は、図４に示すように、２つの画像表示部の隣接方向βが上下方向となるように本体部を回転させる。そして、右目用画像表示部４０の表示面４０ａと左目用画像表示部４１の表示面４１ａとのなす角度αが１８０°未満となるように右目用画像表示部４０を図４の矢印Ａ方向に回転移動させるとともに、ハーフミラー４２を右目用画像表示部４０の表示面４０ａと左目用画像表示部４１の表示面４１ａとの中間に位置するように移動させる。 When displaying a stereoscopic image on this monitor 9, as shown in FIG. 4, the main body is rotated so that the adjacent direction β of the two image display units is the vertical direction. The right-eye image display unit 40 is moved in the direction of arrow A in FIG. 4 so that the angle α formed by the display surface 40a of the right-eye image display unit 40 and the display surface 41a of the left-eye image display unit 41 is less than 180 °. While rotating, the half mirror 42 is moved so as to be positioned between the display surface 40 a of the right-eye image display unit 40 and the display surface 41 a of the left-eye image display unit 41.
　なお、立体視画像表示時の右目用画像表示部４０の表示面４０ａと左目用画像表示部４１の表示面４１ａとのなす角度αは、１８０°未満であれば特に制限はないが、９０°から１２０°程度とするのが好ましく、１１０°とするのが最も好ましい。 The angle α formed between the display surface 40a of the right-eye image display unit 40 and the display surface 41a of the left-eye image display unit 41 during stereoscopic image display is not particularly limited as long as it is less than 180 °, but is 90 °. Is preferably about 120 °, and most preferably 110 °.
　また、ハーフミラー４２は、図４の矢印Ｂ方向に回転可能であり、右目用画像と左目用画像からなる立体視画像の見え方の調整が可能である。 Further, the half mirror 42 can be rotated in the direction of arrow B in FIG. 4, and the appearance of the stereoscopic image composed of the right-eye image and the left-eye image can be adjusted.
　また、本体部、右目用画像表示部４０およびハーフミラー４２の移動は、ユーザーにより手動で行なわせてもよいし、立体視画像表示の指示入力を受け付けるスイッチ等の入力部を設け、この入力部からの指示に基づいて自動的に移動させるようにしてもよいし、モニタ９に入力される放射線画像信号もしくは放射線画像信号の付帯情報等に基づいて立体視画像用の信号が入力されたことを検知した際に、自動的に移動させるようにしてもよい。 Further, the movement of the main body, the right-eye image display unit 40, and the half mirror 42 may be manually performed by a user, or an input unit such as a switch for receiving a stereoscopic image display instruction input is provided. May be automatically moved based on an instruction from a radiographic image, or a radiographic image signal input to the monitor 9 or information on a stereoscopic image input based on incidental information of the radiographic image signal or the like. It may be automatically moved when detected.
　モニタ９に表示される立体視画像の観察は、図４に示すように、右目用画像表示部４０の表示面４０ａに表示された右目用画像がハーフミラー４２で反射し、左目用画像表示部４１の表示面４１ａに表示された左目用画像がハーフミラー４２を透過し、その結果、右目用画像と左目用画像とが光学的に合成され立体視画像として観察できるようになる。 As shown in FIG. 4, the stereoscopic image displayed on the monitor 9 is observed by reflecting the right-eye image displayed on the display surface 40a of the right-eye image display unit 40 with the half mirror 42, and the left-eye image display unit. The left-eye image displayed on the display surface 41a of 41 passes through the half mirror 42. As a result, the right-eye image and the left-eye image are optically synthesized and can be observed as a stereoscopic image.
　なお、右目用画像表示部４０および左目用画像表示部４１の上下の位置関係に制限はなく、どちらが上であっても立体視画像を観察させることができる。 It should be noted that there is no limitation on the upper and lower positional relationship between the right-eye image display unit 40 and the left-eye image display unit 41, and a stereoscopic image can be observed regardless of which is up.
　このモニタ９において、通常画像を表示する際は、図５に示すように、２つの画像表示部の隣接方向βが左右方向となるように本体部を回転させる。なお、このときの右目用画像表示部４０の表示面４０ａと左目用画像表示部４１の表示面４１ａとのなす角度には特に制限はない。またハーフミラー４２は、右目用画像表示部４０の表示面４０ａと左目用画像表示部４１の表示面４１ａとの中間に位置させればよいが、本体部から取外し可能に構成し、通常画像時にハーフミラー４２を取り外すようにすれば、通常画像表示の妨げにならないようにすることができる。 When displaying a normal image on the monitor 9, as shown in FIG. 5, the main body is rotated so that the adjacent direction β of the two image display units is the left-right direction. In addition, there is no restriction | limiting in particular in the angle which the display surface 40a of the image display part 40 for right eyes and the display surface 41a of the image display part 41 for left eyes at this time make. The half mirror 42 may be positioned between the display surface 40a of the right-eye image display unit 40 and the display surface 41a of the left-eye image display unit 41. If the half mirror 42 is removed, normal image display can be prevented.
　ここで、通常画像とは二次元画像であり、立体視画像表示時に表示していた右目用画像および左目用画像を立体視画像としてではなく個別に二次元画像として観察させてもよいし、右目用画像および左目用画像以外の二次元画像を表示させてもよい。 Here, the normal image is a two-dimensional image, and the right-eye image and the left-eye image displayed when the stereoscopic image is displayed may be individually observed as a two-dimensional image instead of a stereoscopic image. A two-dimensional image other than the image for use and the image for the left eye may be displayed.
　また、本体部、右目用画像表示部４０およびハーフミラー４２の移動は、ユーザーにより手動で行なわせてもよいし、通常画像表示の指示入力を受け付けるスイッチ等の入力部を設け、この入力部からの指示に基づいて自動的に移動させるようにしてもよいし、モニタ９に入力される放射線画像信号もしくは放射線画像信号の付帯情報等に基づいて通常画像用の信号が入力されたことを検知した際に、自動的に移動させるようにしてもよい。 Further, the main body unit, the right-eye image display unit 40 and the half mirror 42 may be moved manually by the user, or provided with an input unit such as a switch for receiving an instruction input for normal image display. May be automatically moved on the basis of the instruction, or it is detected that a normal image signal has been input based on the radiation image signal input to the monitor 9 or incidental information of the radiation image signal. At this time, it may be automatically moved.
　次に、本実施形態の乳房用立体視画像撮影表示システムの作用について説明する。 Next, the operation of the breast stereoscopic image capturing and displaying system according to this embodiment will be described.
　まず、撮影の際の動作について説明する。 First, the operation during shooting will be described.
　最初に撮影台１４の上に乳房Ｍが設置され、圧迫板１８により乳房Ｍが所定の圧力によって圧迫される。 First, the breast M is installed on the imaging table 14, and the breast M is compressed by the compression plate 18 with a predetermined pressure.
　次に、入力部７おいて、２つの異なる撮影方向がなす角度（以下、輻輳角θという）および輻輳角θを構成する撮影角度θ'の組み合わせを含む種々の撮影条件が入力された後、撮影開始の指示が入力される。 Next, after various imaging conditions including a combination of an angle formed by two different imaging directions (hereinafter referred to as a convergence angle θ) and an imaging angle θ ′ constituting the convergence angle θ are input in the input unit 7, An instruction to start shooting is input.
　そして、入力部７において撮影開始の指示があると、乳房Ｍの立体視画像の撮影が行われる。具体的には、まず、制御部８ａが、輻輳角θと輻輳角θを構成する撮影角度θ'の情報をアームコントローラ３１に出力する。なお、本実施形態においては、このときの輻輳角θの情報としてθ＝４°、輻輳角θを構成する撮影角度θ’の組み合わせとしてθ’＝±２°の組み合わせが設定されているものとするが、これに限られるものではなく、撮影者は入力部７において任意の輻輳角θを設定可能である。 Then, when an instruction to start photographing is given at the input unit 7, a stereoscopic image of the breast M is photographed. Specifically, first, the control unit 8 a outputs information about the convergence angle θ and the imaging angle θ ′ constituting the convergence angle θ to the arm controller 31. In the present embodiment, θ = 4 ° is set as information on the convergence angle θ at this time, and a combination of θ ′ = ± 2 ° is set as a combination of the imaging angles θ ′ constituting the convergence angle θ. However, the present invention is not limited to this, and the photographer can set an arbitrary convergence angle θ at the input unit 7.
　アームコントローラ３１において、制御部８ａから出力された撮影角度θ’の情報が受け付けられ、アームコントローラ３１は、この撮影角度θ’の情報に基づいて、まず右目用の放射線画像を撮影するためにアーム部１３を検出面１５ａに垂直な方向に対して＋２°傾く撮影角度θ'となる制御信号を出力する。 The arm controller 31 receives the information of the imaging angle θ ′ output from the control unit 8a, and the arm controller 31 first uses the arm to capture a radiographic image for the right eye based on the information of the imaging angle θ ′. The controller 13 outputs a control signal with an imaging angle θ ′ that is inclined + 2 ° with respect to a direction perpendicular to the detection surface 15a.
　アームコントローラ３１から出力された制御信号に応じてアーム部１３が＋２°の位置まで回転する。続いて制御部８ａは、放射線源コントローラ３２および検出器コントローラ３３に対して放射線の照射と放射線画像信号の読出しを行うよう制御信号を出力する。
この制御信号に応じて、放射線源１７から放射線が照射され、乳房Ｍを撮影角度θ'が＋２°の方向から撮影した放射線画像が放射線検出器１５によって検出され、検出器コントローラ３３によって放射線画像信号が読み出され、コンピュータ８のデータ記憶部８ｂに記憶される。 In response to the control signal output from the arm controller 31, the arm unit 13 rotates to a position of + 2 °. Subsequently, the control unit 8a outputs a control signal to the radiation source controller 32 and the detector controller 33 so as to perform radiation irradiation and readout of the radiation image signal.
In accordance with this control signal, radiation is emitted from the radiation source 17, and a radiation image obtained by photographing the breast M from the direction in which the imaging angle θ ′ is + 2 ° is detected by the radiation detector 15. Is read and stored in the data storage unit 8b of the computer 8.
　続いて、まず左目用の放射線画像を撮影するためにアーム部１３を検出面１５ａに垂直な方向に対して－２°傾く撮影角度θ'となる制御信号を出力する。 Subsequently, first, in order to capture a radiographic image for the left eye, a control signal that outputs an imaging angle θ ′ in which the arm unit 13 is inclined by −2 ° with respect to a direction perpendicular to the detection surface 15a is output.
　アームコントローラ３１から出力された制御信号に応じてアーム部１３が－２°の位置まで回転する。続いて制御部８ａは、放射線源コントローラ３２および検出器コントローラ３３に対して放射線の照射と放射線画像信号の読出しを行うよう制御信号を出力する。
この制御信号に応じて、放射線源１７から放射線が照射され、乳房Ｍを撮影角度θ'が－２°の方向から撮影した放射線画像が放射線検出器１５によって検出され、検出器コントローラ３３によって放射線画像信号が読み出され、コンピュータ８のデータ記憶部８ｂに記憶される。 In response to the control signal output from the arm controller 31, the arm unit 13 rotates to a position of -2 °. Subsequently, the control unit 8a outputs a control signal to the radiation source controller 32 and the detector controller 33 so as to perform radiation irradiation and readout of the radiation image signal.
In accordance with this control signal, radiation is emitted from the radiation source 17, and a radiation image obtained by photographing the breast M from the direction in which the imaging angle θ ′ is −2 ° is detected by the radiation detector 15. The signal is read out and stored in the data storage unit 8b of the computer 8.
　次に、立体視画像表示の際の動作について説明する。 Next, the operation when displaying a stereoscopic image will be described.
　まず、コンピュータ８のデータ記憶部８ｂに記憶された右目用放射線画像および左目用放射線画像の２つの放射線画像信号がデータ記憶部８ｂから読み出された後、モニタ９の右目用画像表示部４０の表示面４０ａおよび左目用画像表示部４１の表示面４１ａに各画像が表示される。 First, after two radiographic image signals of a right eye radiographic image and a left eye radiographic image stored in the data storage unit 8b of the computer 8 are read from the data storage unit 8b, the right eye image display unit 40 of the monitor 9 Each image is displayed on the display surface 40a and the display surface 41a of the left-eye image display unit 41.
　この状態で、図４に示すように、２つの画像表示部の隣接方向βが上下方向となるように本体部を回転させた後、右目用画像表示部４０の表示面４０ａと左目用画像表示部４１の表示面４１ａとのなす角度αが１８０°未満となるように右目用画像表示部４０を移動させるとともに、ハーフミラー４２を右目用画像表示部４０の表示面４０ａと左目用画像表示部４１の表示面４１ａとの中間に位置するように移動させれば、立体視画像を観察させることができる。 In this state, as shown in FIG. 4, after rotating the main body so that the adjacent direction β of the two image display units is the vertical direction, the display surface 40 a of the right-eye image display unit 40 and the left-eye image display are displayed. The right-eye image display unit 40 is moved so that the angle α formed with the display surface 41a of the unit 41 is less than 180 °, and the half mirror 42 is moved to the display surface 40a of the right-eye image display unit 40 and the left-eye image display unit. If it moves so that it may be located in the middle of 41 display surfaces 41a, a stereoscopic image can be observed.
　また、通常画像表示時は、図５に示すように、２つの画像表示部の隣接方向βが左右方向となるように本体部を回転させれば、左右の画像を同じ高さで表示させることができる。なお、通常画像の表示については、立体視画像表示時に表示していた右目用画像および左目用画像を立体視画像としてではなく個別に二次元画像として観察させてもよいし、右目用画像および左目用画像以外の二次元画像を表示させてもよい。 Further, when displaying a normal image, as shown in FIG. 5, if the main body is rotated so that the adjacent direction β of the two image display units is the left-right direction, the left and right images can be displayed at the same height. Can do. As for the display of the normal image, the right-eye image and the left-eye image that were displayed when the stereoscopic image was displayed may be individually observed as a two-dimensional image, not as a stereoscopic image, or the right-eye image and the left-eye image may be displayed. A two-dimensional image other than the image for use may be displayed.
　また、２つの画像表示部の隣接方向βを上下方向から左右方向へ移動させるのと連動するようにスタンド４４を伸縮させて、２つの画像表示部の隣接方向βを上下方向としたときの立体視画像の中心の高さと、左右方向としたときの通常画像の中心の高さとが一定になるようにしてもよい。このようにすることで、ユーザーが立体視画像と通常画像を観察する際に視線の高さを変えずに観察することができるので、ユーザーの負担を軽減することができる。 Further, the stand 44 is expanded and contracted so that the adjacent direction β of the two image display units is moved from the up-down direction to the left-right direction, and the three-dimensional view when the adjacent direction β of the two image display units is set to the up-down direction. The center height of the visual image and the center height of the normal image in the left-right direction may be constant. By doing in this way, when a user observes a stereoscopic image and a normal image, it can observe, without changing the height of a line of sight, and a user's burden can be eased.
　なお、上記実施の形態においては、立体視画像表示時は２つの画像表示部の隣接方向βを上下方向とし、通常画像表示時は２つの画像表示部の隣接方向βを左右方向としているが、このような態様に限定されるものではなく、立体視画像表示時および通常画像表示時ともに、ユーザーの好みの状態で使用させることができる。 In the above-described embodiment, the adjacent direction β of the two image display units is set to the vertical direction during stereoscopic image display, and the adjacent direction β of the two image display units is set to the horizontal direction during normal image display. The present invention is not limited to this mode, and can be used in a user's favorite state both when displaying a stereoscopic image and when displaying a normal image.
　以上、本発明の立体視画像表示装置の一実施の形態として、乳房用立体視画像撮影表示システムと組み合わせた例を示したが、本発明は乳房用立体視画像撮影表示システムに限定されるものではなく、例えば胸部や頭部等を撮影する放射線画像撮影装置等、どのようなシステムとも組み合わせることができる。 As described above, as an embodiment of the stereoscopic image display device of the present invention, an example in combination with a breast stereoscopic image photographing display system has been shown. However, the present invention is limited to a breast stereoscopic image photographing display system. Instead, it can be combined with any system, for example, a radiographic imaging device that images the chest, head, and the like.
　また、上記以外にも、本発明の要旨を逸脱しない範囲において、各種の改良や変形を行なってもよいのは勿論である。 Of course, in addition to the above, various improvements and modifications may be made without departing from the scope of the present invention.
