Abstract

Disclosed is a three-dimensional image display device which can minimize a drop in the resolution of a three-dimensional image to be displayed.  The image display device comprises an image generation section which has two-dimensionally-arranged pixels each including a plurality of subpixels which emit image light individually and generates a two-dimensional image or a three-dimensional image by switching, and a polarization control section which differentiates, in each pixel, the polarization state of image light emitted by one of the plurality of subpixels from the polarization state of image light emitted by another subpixel, wherein the image generation section generates either a two-dimensional image using the whole pixels as a unit or a three-dimensional image which includes an image for the right eye using one subpixel as a unit and an image for the left eye using another subpixel as a unit.

Description

画像表示装置Image display device
　本発明は、画像表示装置に関する。 The present invention relates to an image display device.
　液晶ディスプレイと位相差板とを組み合わせた立体画像表示装置が知られている（例えば特許文献１参照）。この立体画像表示装置では、液晶ディスプレイのピクセルを水平方向に対して一ライン毎に右目用ピクセル領域および左目用ピクセル領域を交互に配し、位相差板もそれに対応するように右目領域および左目領域を交互に設けている。 A stereoscopic image display device in which a liquid crystal display and a phase difference plate are combined is known (for example, see Patent Document 1). In this stereoscopic image display device, the pixels of the liquid crystal display are alternately arranged with the right-eye pixel region and the left-eye pixel region for each line in the horizontal direction, and the right-eye region and the left-eye region so that the phase difference plate also corresponds thereto. Are provided alternately.

　上記立体画像表示装置の場合、液晶ディスプレイのピクセルを水平方向に対して一ライン毎に右目用ピクセル領域および左目用ピクセル領域を交互に配しているので、観察者の右目および左目に入るそれぞれの画像情報量は、同じ液晶ディスプレイを平面（二次元）の画像表示に使用した場合に比べ、半分の画像情報量となる。このため、特定の方向、例えば鉛直方向における解像度が低下するという問題点を有していた。 In the case of the stereoscopic image display device, the pixels of the liquid crystal display are alternately arranged with the right-eye pixel region and the left-eye pixel region for each line in the horizontal direction.

　以下、発明の実施の形態を通じて本発明を説明するが、以下の実施形態は請求の範囲にかかる発明を限定するものではない。また、実施形態の中で説明されている特徴の組み合わせのすべてが発明の解決手段に必須であるとは限らない。 Hereinafter, the present invention will be described through embodiments of the invention. However, the following embodiments do not limit the invention according to the claims. Moreover, not all the combinations of features described in the embodiments are essential for the solution means of the invention.
　図１は、立体画像表示装置１００の分解斜視図である。立体画像表示装置１００は、光源１２０、入射側偏光板１５０、画像生成部１６０、出射側偏光板１７０および偏光軸制御板１８０をこの順で備える。立体画像表示装置１００に表示される立体画像を観察者が観察する場合は、図中における偏光軸制御板１８０よりも右側から観察する。 FIG. 1 is an exploded perspective view of the stereoscopic image display device 100. The stereoscopic image display apparatus 100 includes a light source 120, an incident side polarizing plate 150, an image generation unit 160, an output side polarizing plate 170, and a polarization axis control plate 180 in this order. When an observer observes a stereoscopic image displayed on the stereoscopic image display device 100, the observer observes from the right side of the polarization axis control plate 180 in the drawing.
　光源１２０は、観察者から見て立体画像表示装置１００の最も奥側に配される。立体画像表示装置１００に立体画像を表示させている状態（以下、「立体画像表示装置１００の使用状態」と記載する）においては、光源１２０から白色の無偏光を入射側偏光板１５０の全面に向けて出射する。 The light source 120 is disposed on the farthest side of the stereoscopic image display device 100 as viewed from the observer. In a state where a stereoscopic image is displayed on the stereoscopic image display device 100 (hereinafter referred to as “use state of the stereoscopic image display device 100”), white non-polarized light is applied from the light source 120 to the entire surface of the incident-side polarizing plate 150. Exit toward.
　なお、本実施形態では、光源１２０に面光源を用いている。しかしながら、面光源に替えて、例えば点光源と集光レンズとの組み合わせたものを用いてもよい。点光源の一例は発光ダイオード（ＬＥＤ）等であり、集光レンズの一例はフレネルレンズシートである。 In this embodiment, a surface light source is used as the light source 120. However, instead of the surface light source, for example, a combination of a point light source and a condenser lens may be used. An example of the point light source is a light emitting diode (LED) or the like, and an example of the condenser lens is a Fresnel lens sheet.
　入射側偏光板１５０は、画像生成部１６０に対して光源１２０側に配される。入射側偏光板１５０は、透過軸および当該透過軸に直交する吸収軸を有し、光源１２０から出射された無偏光が入射すると透過軸の方向と平行な偏光軸の光を透過し、吸収軸の方向と平行な偏光軸の光を遮断する。 The incident-side polarizing plate 150 is disposed on the light source 120 side with respect to the image generation unit 160. The incident-side polarizing plate 150 has a transmission axis and an absorption axis orthogonal to the transmission axis. When non-polarized light emitted from the light source 120 is incident, the incident-side polarizing plate 150 transmits light having a polarization axis parallel to the direction of the transmission axis. The light of the polarization axis parallel to the direction of is blocked.
　なお、偏光軸の方向とは、光における電界の振動方向のことをいう。図示の入射側偏光板１５０における透過軸の方向は、図中に矢印で示すように、観察者が立体画像表示装置１００を見たときの水平方向に対し右上４５度の方向である。 The direction of the polarization axis refers to the direction of vibration of the electric field in the light. The direction of the transmission axis in the illustrated incident-side polarizing plate 150 is a direction of 45 degrees on the upper right with respect to the horizontal direction when the observer looks at the stereoscopic image display device 100 as indicated by an arrow in the drawing.
　画像生成部１６０は、右目用画像生成領域１６２および左目用画像生成領域１６４を有する。右目用画像生成領域１６２および左目用画像生成領域１６４は、図示のように、画像生成部１６０を水平方向に区切った領域であり、複数の右目用画像生成領域１６２および左目用画像生成領域１６４が鉛直方向に互い違いに配されている。立体画像表示装置１００の使用状態において、画像生成部１６０の右目用画像生成領域１６２および左目用画像生成領域１６４には、それぞれ右目用画像および左目用画像が生成される。 The image generation unit 160 includes a right-eye image generation area 162 and a left-eye image generation area 164. The right-eye image generation area 162 and the left-eye image generation area 164 are areas obtained by dividing the image generation section 160 in the horizontal direction, as shown in the figure, and a plurality of right-eye image generation areas 162 and left-eye image generation areas 164 are provided. They are staggered in the vertical direction. In the usage state of the stereoscopic image display device 100, a right-eye image and a left-eye image are generated in the right-eye image generation region 162 and the left-eye image generation region 164 of the image generation unit 160, respectively.
　入射側偏光板１５０を透過した偏光が、画像生成部１６０の右目用画像生成領域１６２および左目用画像生成領域１６４に入射すると、右目用画像生成領域１６２を透過した偏光は右目用画像の画像光（以下、「右目用画像光」と記載する）となる。また、左目用画像生成領域１６４を透過した偏光は左目用画像の画像光（以下、「左目用画像光」と記載する）となる。 When the polarized light transmitted through the incident-side polarizing plate 150 enters the right-eye image generation region 162 and the left-eye image generation region 164 of the image generation unit 160, the polarized light transmitted through the right-eye image generation region 162 is image light of the right-eye image. (Hereinafter referred to as “right eye image light”). The polarized light transmitted through the left-eye image generation region 164 becomes image light of the left-eye image (hereinafter referred to as “left-eye image light”).
　なお、右目用画像生成領域１６２を透過した右目用画像光と、左目用画像生成領域１６４を透過した左目用画像光とは、それぞれ特定方向の偏光軸を有する直線偏光になる。特定方向の偏光軸とは、右目用画像光と左目用画像光とで互いに同じ方向であってもよい。図示の例においては、共に偏光軸が後述する出射側偏光板１７０の透過軸の方向と同じ方向である。 The right-eye image light that has passed through the right-eye image generation region 162 and the left-eye image light that has passed through the left-eye image generation region 164 are linearly polarized light having a polarization axis in a specific direction. The polarization axis in the specific direction may be the same direction for the right-eye image light and the left-eye image light. In the illustrated example, the polarization axis is the same direction as the transmission axis of the output side polarizing plate 170 described later.
　画像生成部１６０には、二枚の透明基板間に液晶を封止した液晶セルを有する液晶ディスプレイパネルを用いることができる。透明基板の表面に形成されて液晶を駆動する透明電極は、ピクセルの各々を形成する赤領域、緑領域および青領域のそれぞれをさらに上下に分割して、右目用サブピクセルおよび左目用サブピクセルを形成する。画像生成部１６０を水平方向に区切った右目用画像生成領域１６２および左目用画像生成領域１６４は、この右目用サブピクセルおよび左目用サブピクセルにそれぞれ対応するように交互に配される。 The image generation unit 160 may be a liquid crystal display panel having a liquid crystal cell in which liquid crystal is sealed between two transparent substrates. The transparent electrode that is formed on the surface of the transparent substrate and drives the liquid crystal further divides each of the red region, the green region, and the blue region that form each pixel into upper and lower parts, thereby subdividing the right eye subpixel and the left eye subpixel. Form. The right-eye image generation region 162 and the left-eye image generation region 164 obtained by dividing the image generation unit 160 in the horizontal direction are alternately arranged so as to correspond to the right-eye subpixel and the left-eye subpixel, respectively.
　ここで、ピクセルとは、画像を扱うときの単位をいい、色調および階調を有する。画像生成部１６０において、ピクセルは水平方向および鉛直方向に二次元的に配されており、ピクセルの各々は、赤領域、緑領域および青領域を含む。これらの領域の輝度を強めたり弱めたりしながら様々な色を表現することができる。 Here, the pixel means a unit for handling an image and has a color tone and a gradation. In the image generation unit 160, the pixels are two-dimensionally arranged in the horizontal direction and the vertical direction, and each of the pixels includes a red region, a green region, and a blue region. Various colors can be expressed while increasing or decreasing the luminance of these areas.
　出射側偏光板１７０は、画像生成部１６０に対して観察者側に配される。出射側偏光板１７０には、右目用画像生成領域１６２を透過した右目用画像光、および、左目用画像生成領域１６４を透過した左目用画像光が入射する。 The exit side polarizing plate 170 is arranged on the viewer side with respect to the image generation unit 160. Right-eye image light that has passed through the right-eye image generation region 162 and left-eye image light that has passed through the left-eye image generation region 164 are incident on the output-side polarizing plate 170.
　出射側偏光板１７０における透過軸の方向は、図中に矢印で示すように、観察者が立体画像表示装置１００を見たときの水平方向から左上４５度の方向である。出射側偏光板１７０は、入射した右目用画像光および左目用画像光のうち、偏光軸が透過軸と平行な光を透過し、偏光軸が吸収軸と平行な光を遮断する。 The direction of the transmission axis in the exit side polarizing plate 170 is 45 degrees from the horizontal direction when the observer views the stereoscopic image display device 100 as indicated by an arrow in the figure. Outgoing-side polarizing plate 170 transmits light having a polarization axis parallel to the transmission axis and blocking light having a polarization axis parallel to the absorption axis among the incident right-eye image light and left-eye image light.
　偏光軸制御板１８０は、右目偏光領域１８１および左目偏光領域１８２を有する。偏光軸制御板１８０における右目偏光領域１８１および左目偏光領域１８２の位置および大きさは、所定の観察距離をおいて正面の中央位置に配された立体画像表示装置１００を観察した場合に、右目用画像生成領域１６２を透過した右目用画像光が右目偏光領域１８１を通じて観察され、左目用画像生成領域１６４を透過した左目用画像光が左目偏光領域１８２を通じて観察されるように配される。 The polarization axis control plate 180 has a right eye polarization region 181 and a left eye polarization region 182. The positions and sizes of the right-eye polarizing region 181 and the left-eye polarizing region 182 on the polarization axis control plate 180 are for the right eye when the stereoscopic image display device 100 arranged at the front center position with a predetermined observation distance is observed. The right eye image light transmitted through the image generation region 162 is observed through the right eye polarization region 181, and the left eye image light transmitted through the left eye image generation region 164 is observed through the left eye polarization region 182.
　右目偏光領域１８１は、入射した右目用画像光の偏光軸を回転させずにそのまま透過する。左目偏光領域１８２は、入射した左目用画像光の偏光軸を右目偏光領域１８１に入射した右目用画像光の偏光軸に対して直交する方向に回転させる。これにより、右目偏光領域１８１を透過した右目用画像光の偏光軸と、左目偏光領域１８２を透過した左目用画像光の偏光軸とは、図中に矢印で示すように、互いに直交する。 The right-eye polarization region 181 transmits the incident right-eye image light as it is without rotating the polarization axis. The left-eye polarization region 182 rotates the polarization axis of the incident left-eye image light in a direction orthogonal to the polarization axis of the right-eye image light incident on the right-eye polarization region 181. As a result, the polarization axis of the right-eye image light transmitted through the right-eye polarization region 181 and the polarization axis of the left-eye image light transmitted through the left-eye polarization region 182 are orthogonal to each other as indicated by arrows in the drawing.
　なお、図中に示す偏光軸制御板１８０における矢印は、偏光軸制御板１８０を通過した偏光の偏光軸の方向を示す。右目偏光領域１８１には、例えば透明なガラスまたは樹脂などが用いられる。 Note that the arrow on the polarization axis control plate 180 shown in the figure indicates the direction of the polarization axis of the polarized light that has passed through the polarization axis control plate 180. For the right-eye polarizing region 181, for example, transparent glass or resin is used.
　左目偏光領域１８２には、例えば入射される左目用画像光の偏光軸の方向に対して４５度の角度の光学軸を有する１／２波長板が用いられる。図示の例において、左目偏光領域１８２の光学軸の方向は、水平方向または鉛直方向である。ここで、光学軸とは、光が左目偏光領域１８２を通過するときの進相軸または遅相軸の一方を指す。 For the left-eye polarization region 182, for example, a half-wave plate having an optical axis at an angle of 45 degrees with respect to the direction of the polarization axis of the incident left-eye image light is used. In the illustrated example, the direction of the optical axis of the left-eye polarizing region 182 is the horizontal direction or the vertical direction. Here, the optical axis refers to one of a fast axis and a slow axis when light passes through the left-eye polarizing region 182.
　立体画像表示装置１００は、偏光軸制御板１８０よりも観察者側（図示の例では、偏光軸制御板１８０の右側）に、偏光軸制御板１８０の右目偏光領域１８１および左目偏光領域１８２を透過した右目用画像光および左目用画像光を水平方向または鉛直方向の少なくとも一方向の方向に拡散する拡散板を有していてもよい。拡散板としては、例えば水平方向または鉛直方向に延伸するかまぼこ状の凸レンズ（シリンドリカルレンズ）が複数配されたレンチキュラーレンズシート、または凸レンズが平面上に複数配されたレンズアレイシートを用い得る。 The stereoscopic image display apparatus 100 transmits the right-eye polarization region 181 and the left-eye polarization region 182 of the polarization axis control plate 180 closer to the observer side than the polarization axis control plate 180 (right side of the polarization axis control plate 180 in the illustrated example). There may be provided a diffusion plate for diffusing the right-eye image light and the left-eye image light in at least one direction of the horizontal direction or the vertical direction. As the diffusing plate, for example, a lenticular lens sheet in which a plurality of cylindrical convex lenses (cylindrical lenses) extending in the horizontal direction or the vertical direction are arranged, or a lens array sheet in which a plurality of convex lenses are arranged on a plane can be used.
　図２は、立体画像表示システム１０の使用状態を示す概略上面図である。図示のように、立体画像表示システム１０において立体画像を観察する場合、立体画像表示装置１００から投影される右目用画像光および左目用画像光を、観察者５００は偏光眼鏡２００をかけて観察する。偏光眼鏡２００は、観察者５００がこの偏光眼鏡２００をかけたときに観察者５００の右目５１２にあたる位置に配された右目用画像透過部２３２と、左目５１４にあたる位置に配された左目用画像透過部２３４とを有する。 FIG. 2 is a schematic top view showing the usage state of the stereoscopic image display system 10. As shown in the figure, when a stereoscopic image is observed in the stereoscopic image display system 10, the observer 500 observes the right-eye image light and the left-eye image light projected from the stereoscopic image display device 100 with the polarizing glasses 200. . The polarized glasses 200 have a right-eye image transmission unit 232 arranged at a position corresponding to the right eye 512 of the observer 500 when the observer 500 puts on the polarized glasses 200, and a left-eye image transmission arranged at a position corresponding to the left eye 514. Part 234.
　右目用画像透過部２３２は、右目用画像光を透過した右目偏光領域１８１と同じ方向の透過軸方向を有し、且つ、当該透過軸と直交する吸収軸方向を有する偏光板を含む。左目用画像透過部２３４は、左目用画像光を透過した左目偏光領域１８２と同じ方向の透過軸方向を有し、且つ、当該透過軸方向と直交する吸収軸方向を有する偏光板を含む。右目用画像透過部２３２および左目用画像透過部２３４としては、例えば、二色性染料を含浸させたフィルムを一軸延伸して得られる偏光膜を貼り付けた偏光レンズを用い得る。 The right-eye image transmission unit 232 includes a polarizing plate that has the same transmission axis direction as the right-eye polarization region 181 that transmits the right-eye image light and has an absorption axis direction orthogonal to the transmission axis. The left-eye image transmission unit 234 includes a polarizing plate having the same transmission axis direction as that of the left-eye polarizing region 182 that transmits the left-eye image light and having an absorption axis direction orthogonal to the transmission axis direction. As the right-eye image transmission part 232 and the left-eye image transmission part 234, for example, a polarizing lens to which a polarizing film obtained by uniaxially stretching a film impregnated with a dichroic dye can be used.
　観察者５００は、立体画像表示システム１０により立体画像を観察する場合に、偏光軸制御板１８０の右目偏光領域１８１および左目偏光領域１８２を透過した右目用画像光および左目用画像光の出射する範囲内において、上記のように偏光眼鏡２００をかけて立体画像表示装置１００を観察する。これにより、右目５１２では右目用画像光を観察し、左目５１４では左目用画像光を、選択的に観察する。従って、観察者５００は、これら右目用画像光および左目用画像光を合わせて立体画像として認識できる。 When the observer 500 observes a stereoscopic image by the stereoscopic image display system 10, the range in which the right-eye image light and the left-eye image light transmitted through the right-eye polarization region 181 and the left-eye polarization region 182 of the polarization axis control plate 180 are emitted. Inside, the stereoscopic image display apparatus 100 is observed with the polarizing glasses 200 as described above. Accordingly, the right eye 512 observes the right eye image light, and the left eye 514 selectively observes the left eye image light. Therefore, the observer 500 can recognize the right eye image light and the left eye image light together as a stereoscopic image.
　図３は、画像生成部１６０の部分拡大図であり、ピクセル６６０の詳細な構造を示す。図示のように、画像生成部１６０は、水平方向および鉛直方向に二次元的に配列された複数のピクセル６６０を有する。 FIG. 3 is a partially enlarged view of the image generation unit 160 and shows a detailed structure of the pixel 660. As illustrated, the image generation unit 160 includes a plurality of pixels 660 arranged two-dimensionally in the horizontal direction and the vertical direction.
　２次元的に表示される平面画像を生成する場合、画像生成部１６０は、平面画像表示駆動部６８０によりピクセル６６０毎に駆動される。これにより、ピクセル６６０の各々は、平面画像を表示する場合の単位となる。 When generating a two-dimensionally displayed flat image, the image generating unit 160 is driven for each pixel 660 by the flat image display driving unit 680. Thereby, each of the pixels 660 becomes a unit for displaying a planar image.
　また、複数のピクセル６６０の各々は、赤領域（Ｒ）６６２、緑領域（Ｇ）６６４および青領域（Ｂ）６６６を含む。更に、赤領域（Ｒ）６６２、緑領域（Ｇ）６６４および青領域（Ｂ）６６６の各々は、それぞれ上下に分割されている。即ち、赤領域（Ｒ）６６２、緑領域（Ｇ）６６４および青領域（Ｂ）６６６のそれぞれは、上領域６７２、６７４、６７６および下領域６７３、６７５、６７７に分割される。 Each of the plurality of pixels 660 includes a red region (R) 662, a green region (G) 664, and a blue region (B) 666. Further, each of the red region (R) 662, the green region (G) 664, and the blue region (B) 666 is divided vertically. That is, each of the red region (R) 662, the green region (G) 664, and the blue region (B) 666 is divided into an upper region 672, 674, 676 and a lower region 673, 675, 677.
　上領域６７２、６７４、６７６は、右目用画像生成領域１６２に対応して右目用画像生成領域１６２を形成する右目用サブピクセル６７８となる。また、下領域６７３、６７５、６７７は、左目用画像生成領域１６４に対応して左目用画像生成領域１６４を形成する左目用サブピクセル６７９となる。 The upper areas 672, 674, and 676 are right-eye subpixels 678 that form the right-eye image generation area 162 corresponding to the right-eye image generation area 162. The lower regions 673, 675, and 677 are left-eye subpixels 679 that form the left-eye image generation region 164 corresponding to the left-eye image generation region 164.
　右目用画像と左目用画像とを含んで表示される立体画像を生成する場合、画像生成部１６０は、立体画像表示駆動部６９０により駆動される。立体画像表示駆動部６９０の右目用画像表示駆動部６９２は、右目用サブピクセル６７８となる上領域６７２、６７４、６７６を表示の単位として駆動する。また、立体画像表示駆動部６９０の左目用画像表示駆動部６９４は、左目用サブピクセル６７９となる下領域６７３、６７５、６７７を表示の単位として駆動する。 When generating a stereoscopic image that includes a right-eye image and a left-eye image, the image generation unit 160 is driven by the stereoscopic image display driving unit 690. The right-eye image display driving unit 692 of the stereoscopic image display driving unit 690 drives the upper regions 672, 674, and 676 serving as the right-eye sub-pixel 678 as a display unit. In addition, the left-eye image display driving unit 694 of the stereoscopic image display driving unit 690 drives the lower regions 673, 675, and 677 serving as the left-eye sub-pixel 679 as display units.
　図４は、立体画像表示装置１００に二次元的に表示された平面画像を示す図である。立体画像表示装置１００は、光源１２０、入射側偏光板１５０、出射側偏光板１７０および偏光軸制御板１８０の図示を省き、画像生成部１６０により示した。しかしながら、立体画像表示装置１００は図１に示した構造を有する。また、図１および図２と共通の要素には同じ参照番号を付して重複する説明を省く。 FIG. 4 is a diagram showing a planar image displayed two-dimensionally on the stereoscopic image display device 100. The stereoscopic image display apparatus 100 is shown by the image generation unit 160 without the light source 120, the incident side polarizing plate 150, the output side polarizing plate 170, and the polarization axis control plate 180. However, the stereoscopic image display apparatus 100 has the structure shown in FIG. In addition, the same reference numerals are assigned to elements common to those in FIGS. 1 and 2, and redundant description is omitted.
　図示のように、画像生成部１６０は複数のピクセル６６０により形成される（図中ではピクセル６６０のひとつを太線により強調する）。図示の例では、鉛直方向に１１個、水平方向に１１個、それぞれ配列されたピクセル６６０により、樹木を表す樹状形状９００の平面画像を表示している。 As shown in the figure, the image generation unit 160 is formed by a plurality of pixels 660 (in the figure, one of the pixels 660 is highlighted by a thick line). In the example shown in the drawing, a planar image of a tree-like shape 900 representing a tree is displayed by 11 pixels 660 arranged in the vertical direction and 11 in the horizontal direction.
　図５は、立体画像表示システム１０に立体画像が表示された場合に、観察者５００が偏光眼鏡２００をかけて右目５１２で観察する樹状形状９００を示す図である。図中で図３および図４と共通の要素には同じ参照番号を付して重複する説明を省く。 FIG. 5 is a diagram showing a dendritic shape 900 that the observer 500 observes with the right eye 512 wearing the polarizing glasses 200 when a stereoscopic image is displayed on the stereoscopic image display system 10. In the figure, the same elements as those in FIGS. 3 and 4 are denoted by the same reference numerals, and redundant description is omitted.
　表示画像における鉛直方向解像度は、画像生成部１６０の右目用サブピクセル６７８の配置に基づいて決定される。図示の例では、鉛直方向に１１個、水平方向に１１個、それぞれ配列された右目用サブピクセル６７８により樹状形状９００を表示している。 The vertical resolution in the display image is determined based on the arrangement of the right-eye sub-pixels 678 in the image generation unit 160. In the example shown in the figure, the tree shape 900 is displayed by the right-eye sub-pixels 678 arranged in the vertical direction and 11 in the horizontal direction and 11 in the horizontal direction, respectively.
　このように、画像生成部１６０における右目用画像生成領域１６２を右目用サブピクセル６７８に対応させることにより、右目用画像の単位高さ当たりの鉛直方向解像度は、図４に示した平面画像を表示する場合の解像度と変わらない。これにより、右目５１２で観察される樹状形状９００は、樹状形状の輪郭を保持して、片目でも樹状形状９００の細部を認識できる。 In this way, by causing the right-eye image generation area 162 in the image generation unit 160 to correspond to the right-eye subpixel 678, the vertical resolution per unit height of the right-eye image displays the planar image shown in FIG. The resolution is the same as when Thereby, the dendritic shape 900 observed with the right eye 512 retains the outline of the dendritic shape, and the details of the dendritic shape 900 can be recognized even with one eye.
　図６は、立体画像表示システム１０において、観察者５００が偏光眼鏡２００をかけて左目５１４で観察する樹状形状９００である。図中で図３および図４と共通の要素には同じ参照番号を付して重複する説明を省く。 FIG. 6 shows a tree-like shape 900 that the observer 500 observes with the left eye 514 wearing the polarizing glasses 200 in the stereoscopic image display system 10. In the figure, the same elements as those in FIGS. 3 and 4 are denoted by the same reference numerals, and redundant description is omitted.
　右目５１２の場合と同様に、表示画像における鉛直方向解像度は、画像生成部１６０の左目用サブピクセル６７９の配置に基づいて決定される。図示の例では、鉛直方向に１１個、水平方向に１１個、それぞれ配列された左目用サブピクセル６７９により樹状形状９００を表示している。 As in the case of the right eye 512, the vertical resolution in the display image is determined based on the arrangement of the left eye sub-pixels 679 of the image generation unit 160. In the illustrated example, the tree shape 900 is displayed by the left-eye sub-pixels 679 arranged in 11 pieces in the vertical direction and 11 pieces in the horizontal direction.
　このように、画像生成部１６０における左目用画像生成領域１６４を左目用サブピクセル６７９に対応させることにより、左目用画像の単位高さ当たりの鉛直方向解像度は、図４に示した平面画像を表示する場合の解像度と変わらない。これにより、左目５１４で観察される樹状形状９００は、樹状形状の輪郭を保持して、片目でも樹状形状９００の細部を認識できる。 As described above, the left-eye image generation area 164 in the image generation unit 160 corresponds to the left-eye sub-pixel 679 so that the vertical resolution per unit height of the left-eye image displays the planar image shown in FIG. The resolution is the same as when Thereby, the dendritic shape 900 observed with the left eye 514 retains the outline of the dendritic shape, and the details of the dendritic shape 900 can be recognized even with one eye.
　従って、偏光眼鏡２００をかけた観察者５００が、図５に示した左目用画像と、図６に示した右目用画像とを併せて立体画像表示システム１０を見た場合、図４に示した平面画像と同じ解像度を有する立体画像を観察できる。 Therefore, when the observer 500 wearing the polarizing glasses 200 views the stereoscopic image display system 10 together with the left-eye image shown in FIG. 5 and the right-eye image shown in FIG. A stereoscopic image having the same resolution as the planar image can be observed.
　図７は、上記形態と比較のために示す他の立体画像表示装置９９において、平面画像を表示した状態を示す図である。図４と同様に、光源１２０、入射側偏光板１５０、出射側偏光板１７０および偏光軸制御板１８０は図示を省略する。立体画像表示装置９９には、図４と同様に樹状形状９００が表示される。 FIG. 7 is a diagram showing a state in which a planar image is displayed in another stereoscopic image display device 99 shown for comparison with the above embodiment. As in FIG. 4, the light source 120, the incident side polarizing plate 150, the output side polarizing plate 170, and the polarization axis control plate 180 are not shown. The stereoscopic image display device 99 displays a tree shape 900 as in FIG.
　立体画像表示装置９９における画像生成部１６０は、水平方向に区切ったピクセル６６０毎に、右目用画像生成領域１６２および左目用画像生成領域１６４を交互に対応させる。その他の点では、図１から図３までに示した立体画像表示装置１００と同じ構造を有する。 The image generation unit 160 in the stereoscopic image display device 99 causes the right-eye image generation region 162 and the left-eye image generation region 164 to correspond to each other for each pixel 660 partitioned in the horizontal direction. In other respects, it has the same structure as the stereoscopic image display apparatus 100 shown in FIGS.
　図８は、立体画像表示装置９９を用いた立体画像表示システム１０において、観察者５００が偏光眼鏡２００をかけて右目５１２で観察する樹状形状９００を示す。右目用画像生成領域１６２には、鉛直方向についてひとつおきのピクセル６６０が表示の単位として対応する。よって、図示の例では、鉛直方向に６個、水平方向に１１個のピクセルが右目用画像生成領域１６２を形成する。従って、右目用画像の鉛直方向解像度は、図７に示した平面画像の半分近くになる。 FIG. 8 shows a tree shape 900 that the observer 500 observes with the right eye 512 wearing the polarizing glasses 200 in the stereoscopic image display system 10 using the stereoscopic image display device 99. In the right-eye image generation area 162, every other pixel 660 in the vertical direction corresponds as a display unit. Therefore, in the illustrated example, the right-eye image generation region 162 is formed by 6 pixels in the vertical direction and 11 pixels in the horizontal direction. Accordingly, the vertical resolution of the right-eye image is nearly half that of the planar image shown in FIG.
　このため、図５に示した右目用画像に比較すると鉛直方向解像度が低下して、視認される樹状形状９００の輪郭が粗くなり、右目で認識できる樹状形状９００は不明瞭になる。換言すれば、ピクセル６６０を単位とする立体画像表示装置９９に比較すると、図１から図３までに示した立体画像表示装置１００は、立体画像を表示する場合も、鉛直方向の解像度低下が抑制される。 Therefore, as compared with the image for the right eye shown in FIG. 5, the resolution in the vertical direction is lowered, the contour of the visually recognized dendritic shape 900 becomes rough, and the dendritic shape 900 that can be recognized by the right eye becomes unclear. In other words, as compared with the stereoscopic image display device 99 with the pixel 660 as a unit, the stereoscopic image display device 100 shown in FIGS. 1 to 3 suppresses a decrease in resolution in the vertical direction even when displaying a stereoscopic image. Is done.
　図９は、立体画像表示装置９９を用いた立体画像表示システム１０において、観察者５００が偏光眼鏡２００をかけて左目５１４で観察する樹状形状９００を示す。左目用画像生成領域１６４には、鉛直方向についてひとつおきのピクセル６６０が表示の単位として対応する。よって、図示の例では、鉛直方向に５個、水平方向に１１個のピクセルが左面用画像生成領域１６４を形成する。従って、左目用画像の鉛直方向解像度は、図７に示した平面画像の半分以下になる。 FIG. 9 shows a tree shape 900 that the observer 500 observes with the left eye 514 wearing the polarizing glasses 200 in the stereoscopic image display system 10 using the stereoscopic image display device 99. In the left-eye image generation region 164, every other pixel 660 in the vertical direction corresponds as a display unit. Therefore, in the example shown in the drawing, five pixels in the vertical direction and 11 pixels in the horizontal direction form the left-side image generation region 164. Therefore, the vertical resolution of the left-eye image is less than half that of the planar image shown in FIG.
　このため、図６に示した左目用画像に比較すると鉛直方向解像度が低下して、視認される樹状形状９００の輪郭が粗くなる。このため、左目で認識できる樹状形状９００は不明瞭になる。換言すれば、ピクセル６６０を表示の単位とする立体画像表示装置９９に比較すると、図１から図３までに示した立体画像表示装置１００は、立体画像を表示する場合も、鉛直方向の解像度低下が抑制される。 Therefore, compared with the image for the left eye shown in FIG. 6, the vertical resolution is lowered, and the contour of the dendritic shape 900 that is visually recognized becomes rough. For this reason, the dendritic shape 900 that can be recognized by the left eye becomes unclear. In other words, the stereoscopic image display device 100 shown in FIG. 1 to FIG. 3 has a lower resolution in the vertical direction than the stereoscopic image display device 99 having the pixel 660 as a display unit, even when displaying a stereoscopic image. Is suppressed.
　図１０は、他の立体画像表示装置１０１の分解斜視図である。立体画像表示装置１０１において、図１から図３までに示した立体画像表示装置１００と共通の要素には同じ参照番号を付して重複する説明を省く。 FIG. 10 is an exploded perspective view of another stereoscopic image display apparatus 101. In the stereoscopic image display apparatus 101, the same reference numerals are given to the same elements as those in the stereoscopic image display apparatus 100 shown in FIGS. 1 to 3, and redundant description is omitted.
　立体画像表示装置１０１は、立体画像表示装置１００における偏光軸制御板１８０に替えて、他の構造を有する偏光軸制御板１８５を備える。偏光軸制御板１８５は、右目偏光領域１８６および左目偏光領域１８７を有する。 The stereoscopic image display device 101 includes a polarization axis control plate 185 having another structure instead of the polarization axis control plate 180 in the stereoscopic image display device 100. The polarization axis control plate 185 has a right eye polarization region 186 and a left eye polarization region 187.
　右目偏光領域１８６および左目偏光領域１８７は、いずれもが１／４波長板ではあるが、光学軸は互いに直交する。即ち、右目偏光領域１８６には、例えば光学軸が水平方向である１／４波長板が用いられ、左目偏光領域１８７には、例えば光学軸が鉛直方向である１／４波長板が用いられる。図中において偏光軸制御板１８０の上に示す白抜きの矢印は、偏光軸制御板１８５を通過した偏光の回転方向を示す。 The right-eye polarizing region 186 and the left-eye polarizing region 187 are both quarter-wave plates, but their optical axes are orthogonal to each other. That is, for example, a quarter-wave plate whose optical axis is in the horizontal direction is used for the right-eye polarizing region 186, and a quarter-wave plate whose optical axis is in the vertical direction is used for the left-eye polarizing region 187, for example. In the drawing, the white arrow on the polarization axis control plate 180 indicates the rotation direction of the polarized light that has passed through the polarization axis control plate 185.
　これにより、偏光軸制御板１８５の右目偏光領域１８６および左目偏光領域１８７は、入射した光を、偏光軸が互いに逆方向に回転する円偏光として出射する。即ち、例えば、右目偏光領域１８６は入射した光を右回りの円偏光として出射し、左目偏光領域１８７は入射した光を左回りの円偏光として出射する。 Thereby, the right-eye polarization region 186 and the left-eye polarization region 187 of the polarization axis control plate 185 emit incident light as circularly polarized light whose polarization axes rotate in opposite directions. That is, for example, the right-eye polarizing region 186 emits incident light as clockwise circularly polarized light, and the left-eye polarizing region 187 emits incident light as counterclockwise circularly polarized light.
　偏光軸制御板１８５における右目偏光領域１８６は、図１に示した偏光軸制御板１８０における右目偏光領域１８１と同様に、画像生成部１６０における右目用画像生成領域１６２を形成する右目用サブピクセル６７８に対応する。左目偏光領域１８７も、図１に示した偏光軸制御板１８０における右目偏光領域１８１と同様に、画像生成部１６０における左目用画像生成領域１６４を形成する左目用サブピクセル６７９に対応する。従って、ピクセル６６０の各々において、上領域６７２、６７４、６７６が右目用画像生成領域１６２に対応し、下領域６７３、６７５、６７７が左目用画像生成領域１６４に対応する。 The right-eye polarization region 186 in the polarization axis control plate 185 is similar to the right-eye polarization region 181 in the polarization axis control plate 180 shown in FIG. 1, and the right-eye subpixel 678 that forms the right-eye image generation region 162 in the image generation unit 160. Corresponding to The left-eye polarization region 187 also corresponds to the left-eye sub-pixel 679 that forms the left-eye image generation region 164 in the image generation unit 160, similarly to the right-eye polarization region 181 in the polarization axis control plate 180 illustrated in FIG. Accordingly, in each of the pixels 660, the upper regions 672, 674, and 676 correspond to the right-eye image generation region 162, and the lower regions 673, 675, and 677 correspond to the left-eye image generation region 164.
　立体画像表示装置１０１を観察する場合に観察者５００が装着する偏光眼鏡２００においては、光学軸が互いに直交する１／４波長板が、右目用画像透過部２３２および左目用画像透過部２３４に配される。即ち、例えば、右目用画像透過部２３２として光学軸が水平方向な１／４波長板が、左目用画像透過部２３４として光学軸が鉛直方向である１／４波長板が、それぞれ位相差板として配される。さらに、上記偏光眼鏡２００は、位相差板よりも観察者側に、ともに透過軸の方向が観察者５００から見て右斜め４５度であり、吸収軸方向が上記透過軸方向と直交する方向を有する偏光板を有する。 In the polarizing glasses 200 worn by the observer 500 when observing the stereoscopic image display apparatus 101, quarter-wave plates whose optical axes are orthogonal to each other are arranged in the right-eye image transmission unit 232 and the left-eye image transmission unit 234. Is done. That is, for example, a quarter-wave plate with a horizontal optical axis as the right-eye image transmission unit 232, and a quarter-wave plate with a vertical optical axis as the left-eye image transmission unit 234, respectively, are retardation plates. Arranged. Further, in the polarizing glasses 200, the direction of the transmission axis is 45 degrees to the right when viewed from the observer 500, and the absorption axis direction is perpendicular to the transmission axis direction, closer to the observer side than the retardation plate. It has a polarizing plate.
　１／４波長板は、例えばポリカーボネートにより形成される。観察者５００は、偏光眼鏡２００をかけて立体画像表示装置１０１を観察することにより、右目５１２では右目用画像光を、左目５１４では左目用画像光を、それぞれ個別に観察できる。従って、立体画像表示装置１０１の使用状態において、右目偏光領域１８６には、上記右目用画像生成領域１６２を透過した右目用画像光が入射し、左目偏光領域１８７には、上記左目用画像生成領域１６４を透過した左目用画像光が入射する。 The quarter wave plate is made of polycarbonate, for example. By observing the stereoscopic image display apparatus 101 with the polarizing glasses 200, the observer 500 can individually observe the right eye image light with the right eye 512 and the left eye image light with the left eye 514. Therefore, in the usage state of the stereoscopic image display apparatus 101, the right-eye image light transmitted through the right-eye image generation area 162 is incident on the right-eye polarization area 186, and the left-eye image generation area is input to the left-eye polarization area 187. The image light for the left eye that has passed through 164 enters.
　このように、立体画像表示装置１０１においても、画像生成部１６０における右目用画像生成領域１６２を右目用サブピクセル６７８に、画像生成部１６０における左目用画像生成領域１６４を左目用サブピクセル６７９に対応させることにより、鉛直方向における解像度の低下を抑制できる。 As described above, also in the stereoscopic image display apparatus 101, the right-eye image generation region 162 in the image generation unit 160 corresponds to the right-eye subpixel 678, and the left-eye image generation region 164 in the image generation unit 160 corresponds to the left-eye subpixel 679. By doing so, a decrease in resolution in the vertical direction can be suppressed.
　上記の実施形態からも明らかなように、立体画像表示装置１００、１０１において、画像生成部１６０における右目用画像生成領域１６２を右目用サブピクセル６７８に、左目用画像生成領域１６４を左目用サブピクセル６７９に、それぞれ対応させることにより、鉛直方向における解像度の低下を抑制できる。これにより、鉛直方向における解像度の低下が抑制された立体画像表示装置１００、１０１が提供される。 As is clear from the above embodiment, in the stereoscopic image display devices 100 and 101, the right-eye image generation area 162 in the image generation unit 160 is the right-eye subpixel 678, and the left-eye image generation area 164 is the left-eye subpixel. By corresponding to 679 respectively, a decrease in resolution in the vertical direction can be suppressed. Thereby, the three-dimensional image display apparatuses 100 and 101 in which a decrease in resolution in the vertical direction is suppressed are provided.
　以上、本発明を実施の形態を用いて説明したが、本発明の技術的範囲は上記実施の形態に記載の範囲には限定されない。上記実施の形態に、多様な変更または改良を加え得ることが当業者に明らかである。そのような変更または改良を加えた形態も本発明の技術的範囲に含まれ得ることが請求の範囲の記載から明らかである。 As mentioned above, although this invention was demonstrated using embodiment, the technical scope of this invention is not limited to the range as described in the said embodiment. It will be apparent to those skilled in the art that various modifications or improvements can be added to the above-described embodiment. It is apparent from the scope of the claims that the embodiments added with such changes or improvements can be included in the technical scope of the present invention.
