Description

画像表示装置、表示制御装置、表示制御方法ならびにプログラムImage display device, display control device, display control method, and program
　本発明は、複数の副画素により各画素が構成された表示手段を用いて、右目用画像と左目用画像の２枚の画像からなる立体視用画像を表示する画像表示装置、表示制御装置、表示制御方法ならびにプログラムに関するものである。 The present invention provides an image display device, a display control device, and a display control device that display a stereoscopic image composed of two images, a right-eye image and a left-eye image, using a display unit in which each pixel is configured by a plurality of sub-pixels The present invention relates to a display control method and a program.
　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、被検者に対して互いに異なる方向から放射線を照射し、その被検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 patient is irradiated with radiation from different directions, the radiation transmitted through the subject is detected by a radiation image detector, and a plurality of radiation images having parallax are obtained, and these radiations are acquired. A stereoscopic image is generated based on the image. 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. (For example, see Patent Document 1)
特開２０１０－１１０５７１号公報JP 2010-110571 A
　ところで、上記のような立体視画像を表示するための画像表示装置としては、２つのモニタを用いて右目用画像および左目用画像をそれぞれに表示させて、これらをハーフミラーや偏光グラスなどを用いることで一方の画像は観察者の右目に入射させ、他方の放射線画像は観察者の左目に入射させることによって立体視画像を表示する構成のものや、もしくはパララックスバリア方式やレンチキュラー方式のように、１つのモニタに右目用画像および左目用画像を立体視可能に表示する構成のものが提案されている。 By the way, as an image display apparatus for displaying a stereoscopic image as described above, a right-eye image and a left-eye image are respectively displayed using two monitors, and these are used by a half mirror, a polarizing glass, or the like. Thus, one image is incident on the right eye of the observer, and the other radiographic image is incident on the left eye of the observer so that a stereoscopic image is displayed, or a parallax barrier method or a lenticular method. A configuration has been proposed in which a right-eye image and a left-eye image are displayed on a single monitor in a stereoscopic manner.
　従来から用いられている通常画像用のモニタを立体視画像用の表示装置として利用できれば、ユーザーは少ない追加コストで立体視画像用の画像表示装置を構築できるようになるため魅力的であるが、立体視画像を表示するためには通常画像用のモニタには無い特別な構成が必要となるため、従来の通常画像用のモニタを立体視画像用のモニタとして利用することは困難であった。 If a conventionally used monitor for normal images can be used as a display device for stereoscopic images, it is attractive because a user can construct an image display device for stereoscopic images at a small additional cost. In order to display a stereoscopic image, a special configuration that is not included in the monitor for a normal image is required. Therefore, it has been difficult to use a conventional monitor for a normal image as a monitor for a stereoscopic image.
　本発明は、上記の事情に鑑み、従来の通常画像用のモニタ（表示手段）を立体視画像用のモニタとして利用することが可能な画像表示装置、表示制御装置、表示制御方法ならびにプログラムを提供することを目的とする。 In view of the above circumstances, the present invention provides an image display device, a display control device, a display control method, and a program that can use a conventional monitor for normal images (display means) as a monitor for stereoscopic images. The purpose is to do.
　本発明の画像表示装置は、複数の副画素により各画素が構成された表示手段を用いて、右目用画像と左目用画像の２枚の画像からなる立体視用画像を表示する画像表示装置であって、各画素を構成する複数の副画素のうち一部の副画素を用いて右目用画像を表示させ、各画素を構成する複数の副画素のうち右目用画像の表示に用いなかった副画素を用いて左目用画像を表示させる表示制御手段を備えたことを特徴とするものである。 The image display apparatus of the present invention is an image display apparatus that displays a stereoscopic image composed of two images, a right-eye image and a left-eye image, using display means in which each pixel is configured by a plurality of sub-pixels. The right-eye image is displayed using some of the plurality of sub-pixels constituting each pixel and the right-eye image is not used for displaying the right-eye image among the plurality of sub-pixels constituting each pixel. The display control means for displaying a left-eye image using pixels is provided.
　本発明の画像表示装置においては、複数の副画素が、Ｒ、Ｇ、Ｂの３色の副画素であり、表示制御手段が、ＲおよびＧの組合せもしくはＧおよびＢの組合せのいずれかの副画素を用いて、右目用画像もしくは左目用画像のうち一方を表示させ、残りの副画素を用いて、右目用画像もしくは左目用画像のうち他方を表示させるものとしてもよい。 In the image display device of the present invention, the plurality of sub-pixels are R, G, and B sub-pixels, and the display control means uses either a combination of R and G or a combination of G and B. One of the right-eye image and the left-eye image may be displayed using the pixels, and the other of the right-eye image and the left-eye image may be displayed using the remaining sub-pixels.

The radiation source controller 32 controls the timing of irradiating radiation from the radiation source 17 and the radiation generation conditions (tube current, tube voltage, time, etc.) in the radiation source 17.
　また、アーム部１３の中央部には、撮影台１４の上方に配置されて乳房Ｍを押さえつけて圧迫する圧迫板１８と、その圧迫板１８を支持する支持部２０と、支持部２０を上下方向（Ｚ方向）に移動させる移動機構１９が設けられている。圧迫板１８の位置、圧迫圧は、圧迫板コントローラ３４により制御される。 Further, in the central portion of the arm portion 13, a compression plate 18 that is disposed above the imaging table 14 and presses and compresses the breast M, a support portion 20 that supports the compression plate 18, and a support portion 20 that extends in the vertical direction.

Can be used.
　次に、本実施形態の乳房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 image radiographing display system of this embodiment 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のステレオ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、本実施の形態においては、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’＝０°とθ’＝４°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。なお、輻輳角θは小さすぎても大きすぎても適切な立体視を行なわせることが難しくなるため、４°以上１５°以下に設定されることが望ましい。なお、撮影角度θ’の組み合わせとしては、上記の一方の撮影角度θ’、すなわち２次元観察用の画像を撮影するための撮影角度θ’は０°とすることが望ましい。これは、放射線画像検出器１５の正面から撮影した画像が、最も２次元観察に適しているからである。 Then, when there is an instruction to start photographing at the input unit 7, a stereo 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 this embodiment, the information of the convergence angle θ at this time is θ = 4 °, and the combination of the imaging angle θ ′ constituting the convergence angle θ is a combination of θ ′ = 0 ° and θ ′ = 4 °. However, the present invention is not limited to this, and the photographer can set an arbitrary convergence angle θ at the input unit 7. Note that the convergence angle θ is preferably set to 4 ° or more and 15 ° or less because it is difficult to perform appropriate stereoscopic viewing if the convergence angle θ is too small or too large. As a combination of the shooting angle θ ′, the one shooting angle θ ′ described above, that is, the shooting angle θ ′ for shooting an image for two-dimensional observation is preferably 0 °. This is because an image taken from the front of the radiation image detector 15 is most suitable for two-dimensional observation.
　アームコントローラ３１において、制御部８ａから出力された輻輳角θの情報が受け付けられ、アームコントローラ３１は、この輻輳角θの情報に基づいて、アーム部１３が撮影台１４に垂直な方向となるよう制御信号を出力する。すなわち、本実施形態においては、アーム部１３を検出面１５ａに垂直な方向とする撮影角度θ'が０°となる制御信号を出力する。 The arm controller 31 receives the information on the convergence angle θ output from the control unit 8a, and the arm controller 31 causes the arm unit 13 to be in a direction perpendicular to the imaging table 14 based on the information on the convergence angle θ. Output a control signal. In other words, in the present embodiment, a control signal is output so that the shooting angle θ ′ with the arm 13 in the direction perpendicular to the detection surface 15a is 0 °.
　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０°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０°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 the 0 ° position. 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 where the imaging angle θ ′ is 0 ° is detected by the radiation detector 15. Is read and stored in the data storage unit 8b of the computer 8.
　続いて、アーム部１３を検出面１５ａに垂直な方向に対して４°傾く撮影角度θ'となる制御信号を出力する。 Subsequently, a control signal that outputs the imaging angle θ ′ at which the arm unit 13 is inclined by 4 ° with respect to the 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４°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４°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 portion 13 rotates to a position of 4 °. 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 4 ° is detected by the radiation detector 15, and a radiation image signal is detected by the detector controller 33. Is read 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、モニタ９に立体視画像を表示させる際は、コンピュータ８のデータ記憶部８ｂに記憶された右目用画像および左目用画像となる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、表示制御手段としての機能を有する制御部８ａにより、モニタ９の副画素ＳＰのうちＲおよびＧの組合せを用いて右目用画像をモニタ９に表示させ、Ｂを用いて左目用画像をモニタ９に表示させる。これにより、モニタ９には、右目用画像と左目用画像とが同じ画面上に同時に表示されることになる。 First, when displaying a stereoscopic image on the monitor 9, two radiographic image signals to be a right-eye image and a left-eye image stored in the data storage unit 8b of the computer 8 are read from the data storage unit 8b and displayed. The control unit 8a having a function as control means displays the right-eye image on the monitor 9 using a combination of R and G among the sub-pixels SP of the monitor 9, and displays the left-eye image on the monitor 9 using B. Let As a result, the right-eye image and the left-eye image are simultaneously displayed on the same screen on the monitor 9.
　なお、右目用画像および左目用画像が、左右で被写体に対する撮影角度が異なる放射線画像の場合には、撮影角度が小さい方の画像の方が診断を行う上でより重要な画像となる。本実施の形態の場合には、撮影角度θ’が０°と４°で撮影を行っているため、撮影角度θ’が０°で取得した画像の方が診断を行う上でより重要な画像となる。 Note that when the right-eye image and the left-eye image are radiographic images having different imaging angles with respect to the subject on the left and right, the image with the smaller imaging angle is a more important image for diagnosis. In the case of the present embodiment, since imaging is performed at imaging angles θ ′ of 0 ° and 4 °, an image acquired at an imaging angle θ ′ of 0 ° is more important for diagnosis. It becomes.
　そのため、撮影角度θ’が０°で取得した画像を、２つの副画素を用いる右目用画像として表示することが好ましい。これは、表示に使用する副画素が多い方が、表示解像度および表示階調ともに有利になるからである。 Therefore, it is preferable to display an image acquired at an imaging angle θ ′ of 0 ° as a right-eye image using two subpixels. This is because a larger number of subpixels used for display is advantageous in both display resolution and display gradation.
　ユーザーは、右目用画像を観察する右目用カラーフィルタ（ＲおよびＧのみ透過）および左目用画像を観察する左目用カラーフィルタ（Ｂのみ透過）を有するカラーメガネを装着し、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 user wears color glasses having a color filter for the right eye that observes the image for the right eye (only R and G are transmitted) and a color filter for the left eye that observes the image for the left eye (only transmits B), and the image for the left eye and the image for the right eye A stereoscopic image can be observed by observing the image with the left and right eyes.
　このような態様とすることにより、従来からあるモニタ９を立体視画像用のモニタとして利用することが可能となる。 By adopting such an aspect, the conventional monitor 9 can be used as a monitor for stereoscopic images.
　なお、本実施形態において、左目用画像および右目用画像を表示する副画素の態様は上記に限るものではなく、適宜変更することが可能である。 In the present embodiment, the aspect of the sub-pixel that displays the left-eye image and the right-eye image is not limited to the above, and can be changed as appropriate.
　例えば、Ｇの副画素を用いて右目用画像および左目用画像に共通に合成する文字等の共通情報を表示させ、ＲもしくはＢのいずれかの副画素を用いて、右目用画像もしくは左目用画像のうち一方を表示させ、残りの副画素を用いて、右目用画像もしくは左目用画像のうち他方を表示させるものとしてもよい。 For example, the G sub-pixel is used to display common information such as characters that are commonly combined with the right-eye image and the left-eye image, and the right-eye image or the left-eye image is displayed using either the R or B sub-pixel. One of the images may be displayed, and the other of the right-eye image and the left-eye image may be displayed using the remaining sub-pixels.
　なお、このような態様とした場合、カラーメガネの右目用カラーフィルタは右目用画像を表示する色と共通情報を表示する色のみ透過するもの、左目用カラーフィルタは左目用画像を表示する色と共通情報を表示する色のみ透過するものとする必要がある。この場合には、文字等の共通情報は左右の目で同じように見えるようになり、左右で視差が生じないため、共通情報については立体的に見えることはない。 In such a case, the color filter for the right eye of the color glasses transmits only the color for displaying the right eye image and the color for displaying the common information, and the color filter for the left eye has the color for displaying the image for the left eye. Only the color for displaying the common information needs to be transparent. In this case, the common information such as characters will look the same with the left and right eyes, and no parallax will occur between the left and right, so the common information will not appear three-dimensional.
　次に本発明の第２の実施形態について説明する。本実施の形態の乳房用立体視画像撮影表示システムは、モニタ９の構成のみが上記第１の実施の形態の乳房用立体視画像撮影表示システムと異なる。従って、第１の実施の形態と同様の構成要素についての説明は、特に必要のない限り省略する。図５は本発明の第２の実施の形態の画像表示装置のモニタの画素構成を示す部分拡大図である。 Next, a second embodiment of the present invention will be described. The breast stereoscopic image capturing and displaying system according to the present embodiment is different from the breast stereoscopic image capturing and displaying system according to the first embodiment only in the configuration of the monitor 9. Therefore, the description of the same components as those in the first embodiment is omitted unless particularly necessary. FIG. 5 is a partially enlarged view showing the pixel configuration of the monitor of the image display apparatus according to the second embodiment of the present invention.
　本実施の形態の表示手段としてのモニタ９は、図５に示すように、Ｒ、Ｙ、Ｇ、Ｂの４色の副画素ＳＰにより各画素Ｐが構成されたものであって、ＣＲＴモニタ、液晶モニタ、有機ＥＬモニタ等の既存のものを用いることができる。 As shown in FIG. 5, the monitor 9 as a display unit of the present embodiment is configured such that each pixel P is composed of four sub-pixels SP of R, Y, G, and B, and includes a CRT monitor, Existing ones such as a liquid crystal monitor and an organic EL monitor can be used.
　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、モニタ９に立体視画像を表示させる際は、コンピュータ８のデータ記憶部８ｂに記憶された右目用画像および左目用画像となる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、表示制御手段としての機能を有する制御部８ａにより、モニタ９の副画素ＳＰのうちＲおよびＹの組合せを用いて右目用画像をモニタ９に表示させ、ＧおよびＢの組合せを用いて左目用画像をモニタ９に表示させる。これにより、モニタ９には、右目用画像と左目用画像とが同じ画面上に同時に表示されることになる。 First, when displaying a stereoscopic image on the monitor 9, two radiographic image signals to be a right-eye image and a left-eye image stored in the data storage unit 8b of the computer 8 are read from the data storage unit 8b and displayed. The control unit 8a having a function as control means causes the right eye image to be displayed on the monitor 9 using a combination of R and Y among the sub-pixels SP of the monitor 9, and the left eye image is displayed using a combination of G and B. It is displayed on the monitor 9. As a result, the right-eye image and the left-eye image are simultaneously displayed on the same screen on the monitor 9.
　ユーザーは、右目用画像を観察する右目用カラーフィルタ（ＲおよびＹのみ透過）および左目用画像を観察する左目用カラーフィルタ（ＧおよびＢのみ透過）を有するカラーメガネを装着し、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 user wears color glasses having a right-eye color filter for observing the right-eye image (only R and Y are transmitted) and a left-eye color filter for observing the left-eye image (only G and B are transmitted), and the left-eye image and A stereoscopic image can be observed by observing the right-eye image with the left and right eyes.
　このような態様としても、上記第１の実施の形態と同様の効果を得ることができる。 Also in this aspect, the same effect as that of the first embodiment can be obtained.
　なお、本実施形態において、左目用画像および右目用画像を表示する副画素の態様は上記に限るものではなく、適宜変更することが可能である。 In the present embodiment, the aspect of the sub-pixel that displays the left-eye image and the right-eye image is not limited to the above, and can be changed as appropriate.
　例えば、ＹもしくはＧのいずれかの副画素を用いて右目用画像および左目用画像に共通に合成する文字等の共通情報を表示させ、ＹもしくはＧのうち共通情報の表示に用いなかった副画素およびＲもしくはＢのいずれかの副画素の組合せを用いて、右目用画像もしくは左目用画像のうち一方を表示させ、残りの副画素を用いて、右目用画像もしくは左目用画像のうち他方を表示させるものとしてもよい。 For example, common information such as characters to be combined in the right-eye image and the left-eye image using either Y or G sub-pixels is displayed, and the sub-pixels that are not used for displaying the common information of Y or G And one of the right-eye image and left-eye image is displayed using a combination of R and B sub-pixels, and the other of the right-eye image and left-eye image is displayed using the remaining sub-pixels. It is good also as what makes it.
　この場合には、上記第１の実施の形態と同様に、撮影角度が小さい方の画像を、２色の副画素を用いて表示させることが好ましい。 In this case, as in the first embodiment, it is preferable to display an image with a smaller shooting angle using two-color sub-pixels.
　なお、このような態様とした場合、カラーメガネの右目用カラーフィルタは右目用画像を表示する色と共通情報を表示する色のみ透過するもの、左目用カラーフィルタは左目用画像を表示する色と共通情報を表示する色のみ透過するものとする必要がある。この場合には、文字等の共通情報は左右の目で同じように見えるようになり、左右で視差が生じないため、共通情報については立体的に見えることはない。 In such a case, the color filter for the right eye of the color glasses transmits only the color for displaying the right eye image and the color for displaying the common information, and the color filter for the left eye has the color for displaying the image for the left eye. Only the color for displaying the common information needs to be transparent. In this case, the common information such as characters will look the same with the left and right eyes, and no parallax will occur between the left and right, so the common information will not appear three-dimensional.
　以上、本発明の好ましい実施の形態について説明したが、本発明は上記実施の形態に限定されるものではない。 The preferred embodiment of the present invention has been described above, but the present invention is not limited to the above embodiment.
　例えば、モニタの各画素における副画素の色数は、上記で説明したような３色または４色に限定されるものではなく、２色、もしくは５色以上の色数としてもよい。 For example, the number of subpixels in each pixel of the monitor is not limited to three or four colors as described above, and may be two or five or more colors.
　また、上記実施の形態の説明では、本発明の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。 Moreover, in the description of the above embodiment, an example in which the image display apparatus according to the present invention is combined with a breast stereoscopic image capturing / displaying system has been described. The present invention is not limited to the system, and can be combined with any system such as a radiographic image capturing apparatus 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.
