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、左右横並びの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光学的に合成して立体視画像を表示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、３参照）
　このような方式の立体視画像表示装置における表示画面は、通常画像を表示するためのものと全く同じものとすることができるため、立体視画像の表示と通常画像の表示とを兼用できるようにすることが好ましいが、その場合、通常画像表示時にハーフミラーが表示の妨げとなってしまうという問題がある。 By the way, as a stereoscopic image display device for displaying a stereoscopic image as described above, it is provided with two display screens arranged side by side and a half mirror, and displays a right eye image and a left eye image on each display screen. There has been proposed a monitor that displays a stereoscopic image by optically synthesizing a right-eye image and a left-eye image with a half mirror. (For example, see Patent Documents 2 and 3)
Since the display screen in the stereoscopic image display apparatus of such a system can be the same as that for displaying a normal image, the display of the stereoscopic image and the display of the normal image can be combined. However, in this case, there is a problem that the half mirror interferes with display during normal image display.
　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.

The right-eye image display means for displaying the normal image and the right-eye image display means are arranged side by side, and the left-eye image display means for displaying the left-eye image and the normal image, and the right-eye image and the left-eye image are stereoscopically viewed. A half mirror that is optically combined so that it can be viewed as an image, and the half mirror is in the vicinity of the display surface of the right-eye image display means from an intermediate position between the display surface of the right-eye image display means and the display surface of the left-eye image display means And / or one end of the half mirror is rotatably held in the vicinity of the vicinity of the right-eye image display means and the left-eye image display means so that it can move to the vicinity of the display surface of the left-eye image display means. It is characterized in.
　本発明の立体視画像表示装置は、ハーフミラーを１枚のみ備えたものとしてもよいし、ハーフミラーを２枚備え、右目用画像表示手段用のハーフミラーは右目用画像表示手段の表示面と左目用画像表示手段の表示面との中間位置から右目用画像表示手段の表示面近傍まで移動可能なように保持され、左目用画像表示手段用のハーフミラーは右目用画像表示手段の表示面と左目用画像表示手段の表示面との中間位置から左目用画像表示手段の表示面近傍まで移動可能なように保持されたものとしてもよい。 The stereoscopic image display apparatus of the present invention may be provided with only one half mirror, or may be provided with two half mirrors, and the half mirror for the right eye image display means may include a display surface of the right eye image display means. The half mirror for the left-eye image display means and the display surface of the right-eye image display means are held so as to be movable from an intermediate position with respect to the display surface of the left-eye image display means to the vicinity of the display surface of the right-eye image display means. It may be held so as to be movable from an intermediate position with respect to the display surface of the left-eye image display means to the vicinity of the display surface of the left-eye image display means.
　また、ハーフミラーが右目用画像表示手段の表示面近傍および／または左目用画像表示手段の表示面近傍にあることを検知するハーフミラー位置検出手段と、ハーフミラーが右目用画像表示手段の表示面近傍および／または左目用画像表示手段の表示面近傍にある際に、表示面近傍にハーフミラーがある画像表示手段における画像の表示輝度を上げる表示制御手段とを備えたものとすることが好ましい。 Further, half mirror position detecting means for detecting that the half mirror is in the vicinity of the display surface of the right-eye image display means and / or the display surface of the left-eye image display means, and the half mirror is the display surface of the right-eye image display means It is preferable to include display control means for increasing the display brightness of the image in the image display means having a half mirror near the display surface when in the vicinity and / or in the vicinity of the display surface of the left-eye image display means.
　本発明の立体視画像表示装置によれば、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立体視画像表示装置において、右目用画像および通常画像を表示する右目用画像表示手段と、右目用画像表示手段と横並びに配され、左目用画像および通常画像を表示する左目用画像表示手段と、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とを備え、ハーフミラーが右目用画像表示手段の表示面と左目用画像表示手段の表示面との中間位置から右目用画像表示手段の表示面近傍および／または左目用画像表示手段の表示面近傍まで移動可能なように、ハーフミラーの一端が右目用画像表示手段と左目用画像表示手段との近接部付近において回転自在に保持されたものとしたことにより、ハーフミラーを右目用画像表示手段の表示面近傍および／または左目用画像表示手段の表示面近傍まで移動させた状態では、右目用画像と左目用画像とが光学的に合成されず、ハーフミラーに近接する画像表示手段に表示された画像のみが透過表示されるようになるため、立体視画像の表示と通常画像の表示とを兼用可能とすることができる。 According to the stereoscopic image display device of the present invention, in the stereoscopic image display device capable of displaying both a stereoscopic image and a normal image using two images of a right eye image and a left eye image, The right-eye image display means for displaying the normal image and the right-eye image display means are arranged side by side, and the left-eye image display means for displaying the left-eye image and the normal image, and the right-eye image and the left-eye image are stereoscopically viewed. A half mirror that is optically combined so that it can be viewed as an image, and the half mirror is in the vicinity of the display surface of the right-eye image display means from an intermediate position between the display surface of the right-eye image display means and the display surface of the left-eye image display means And / or one end of the half mirror is rotatably held in the vicinity of the vicinity of the right-eye image display means and the left-eye image display means so that it can move to the vicinity of the display surface of the left-eye image display means. As a result, when the half mirror is moved to the vicinity of the display surface of the right-eye image display means and / or the display surface of the left-eye image display means, the right-eye image and the left-eye image are optically Since only the image that is not synthesized and displayed on the image display means close to the half mirror is transparently displayed, the stereoscopic image display and the normal image display can be combined.
　なお、ハーフミラーを１枚のみ備えたものとした場合には、通常画像表示時にハーフミラーに近接する画像表示手段に表示される画像はハーフミラー越しに観察されることになるので、反対側の画像表示手段に表示される画像よりも暗く表示されることになる。そのため、ハーフミラーを２枚備え、右目用画像表示手段用のハーフミラーは右目用画像表示手段の表示面と左目用画像表示手段の表示面との中間位置から右目用画像表示手段の表示面近傍まで移動可能なように保持され、左目用画像表示手段用のハーフミラーは右目用画像表示手段の表示面と左目用画像表示手段の表示面との中間位置から左目用画像表示手段の表示面近傍まで移動可能なように保持されたものとすれば、通常画像表示時に両方の画像表示手段に表示される画像の見え方の状態を略等しくできる。 If only one half mirror is provided, the image displayed on the image display means close to the half mirror during normal image display is observed through the half mirror. It is displayed darker than the image displayed on the image display means. Therefore, two half mirrors are provided, and the half mirror for the right-eye image display means is in the vicinity of the display surface of the right-eye image display means from an intermediate position between the display face of the right-eye image display means and the display face of the left-eye image display means. The half mirror for the left-eye image display means is in the vicinity of the display surface of the left-eye image display means from an intermediate position between the display face of the right-eye image display means and the display face of the left-eye image display means. If the image is held so as to be movable, the state of the appearance of the images displayed on both the image display means during normal image display can be made substantially equal.
　また、ハーフミラーが右目用画像表示手段の表示面近傍および／または左目用画像表示手段の表示面近傍にあることを検知するハーフミラー位置検出手段と、ハーフミラーが右目用画像表示手段の表示面近傍および／または左目用画像表示手段の表示面近傍にある際に、表示面近傍にハーフミラーがある画像表示手段における画像の表示輝度を上げる表示制御手段とを備えたものとすれば、ハーフミラーによる輝度の低下を補って、見やすい画像を表示することができる。 Further, half mirror position detecting means for detecting that the half mirror is in the vicinity of the display surface of the right-eye image display means and / or the display surface of the left-eye image display means, and the half mirror is the display surface of the right-eye image display means If it is provided with a display control means for increasing the display brightness of the image in the image display means having a half mirror in the vicinity of the display surface when in the vicinity and / or in the vicinity of the display surface of the left-eye image display means, the half mirror It is possible to display an easy-to-see image that compensates for the decrease in luminance due to the above.

また、右目用画像表示部４０および左目用画像表示部４１内には、上記センサによりハーフミラー４２が表示面の近傍にあることが検知された際に、画像の表示輝度を上げる不図示の表示制御手段が設けられている。 The monitor 9 is capable of displaying both a stereoscopic image and a normal image using two images of a right eye image and a left eye image.

In addition, a sensor (not shown) that detects that the half mirror 42 is in the vicinity of the display surface 40 a of the right-eye image display unit 40 or the display surface 41 a of the left-eye image display unit 41 is provided in the hinge 43. .
Further, in the right-eye image display unit 40 and the left-eye image display unit 41, a display (not shown) that increases the display brightness of the image when the sensor detects that the half mirror 42 is in the vicinity of the display surface. Control means are provided.
　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.
　このモニタ９において、立体視画像を表示する際は、図５に示すように、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る。 When displaying a stereoscopic image on the monitor 9, as shown in FIG. 5, the angle 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 °. The right-eye image display unit 40 is moved so that the half-eye mirror 42 is moved, and the half mirror 42 is moved so as to 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. .
　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とのなす角度は、１８０°未満であれば特に制限はないが、８０°から１２０°程度とするのが好ましく、９０°とするのが最も好ましい。 The angle 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 °. The angle is preferably about 120 °, and most preferably 90 °.
　また、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 right-eye image display unit 40 and the half mirror 42 may be manually performed by the user, or an input unit such as a switch for receiving a stereoscopic image display instruction input is provided. Or a radiographic image signal input to the monitor 9 or when it is detected that a signal for a stereoscopic image is input based on incidental information of the radiographic image signal or the like. Alternatively, it may be moved automatically.
　モニタ９に表示される立体視画像の観察は、図５中右側からでも左側からでもどちらでも行なえるが、ここでは右側から観察するものとして、立体視画像表示の仕組みを説明する。図５に示すように、モニタ９の右側から立体視画像を観察する場合、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はハーフミラー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はハーフミラー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表示される。なお、モニタ９の左側から立体視画像を観察する場合、反射する画像と透過する画像が逆になるだけで、右側から立体視画像を観察する場合と同様の立体視画像が表示される。 The observation of the stereoscopic image displayed on the monitor 9 can be performed from either the right side or the left side in FIG. 5, but here, the mechanism of the stereoscopic image display will be described as observing from the right side. As shown in FIG. 5, when a stereoscopic image is observed from the right side of the monitor 9, the right-eye image displayed on the display surface 40 a of the right-eye image display unit 40 is reflected by 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, and as a result, the right-eye image and the left-eye image are optically combined and displayed as a stereoscopic image. Note that, when a stereoscopic image is observed from the left side of the monitor 9, only the reflected image and the transmitted image are reversed, and a stereoscopic image similar to the case of observing the stereoscopic image from the right side is displayed.
　このモニタ９において、通常画像を表示する際は、図６に示すように、ハーフミラー４２を右目用画像表示部４０の表示面４０ａ近傍（もしくは左目用画像表示部４１の表示面４１ａ近傍）まで移動させる。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。 When displaying a normal image on the monitor 9, as shown in FIG. 6, the half mirror 42 is moved to the vicinity of the display surface 40 a of the right-eye image display unit 40 (or the vicinity of the display surface 41 a of the left-eye image display unit 41). Move. 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.
　なお、通常画像とは、右目用画像および左目用画像以外の二次元画像だけでなく、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する場合も含む。 The normal image includes not only a two-dimensional image other than the right-eye image and the left-eye image but also a case where the right-eye image and the left-eye image are individually observed as a two-dimensional image instead of a stereoscopic image.
　また、ヒンジ４３内の不図示のセンサによりハーフミラー４２が右目用画像表示部４０の表示面４０ａ近傍にあることが検知された際は、右目用画像表示部４０内の不図示の表示制御手段により、表示面４０ａに表示する画像の表示輝度を上げる処理を行う。 Further, when a sensor (not shown) in the hinge 43 detects that the half mirror 42 is in the vicinity of the display surface 40a of the right-eye image display unit 40, a display control unit (not shown) in the right-eye image display unit 40. Thus, processing for increasing the display brightness of the image displayed on the display surface 40a is performed.
　基本的にハーフミラー４２を透過すると輝度が約半分となるため、表示輝度を２倍程度上げればハーフミラー４２を透過させない場合と同程度の輝度とすることができるが、この値に限定するものではなく、どのような態様としてもよい。 Basically, when the light passes through the half mirror 42, the luminance is approximately halved. Therefore, if the display luminance is increased by about twice, the luminance can be the same as that when the half mirror 42 is not transmitted, but this value is limited. Instead, any mode may be used.

May be.
　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.
