　以下、図１～図７に基づいて、本実施の形態に係る電子機器１について説明する。 [Embodiment 1]
Hereinafter, the electronic apparatus 1 according to the present embodiment will be described with reference to FIGS.
　図１は、電子機器１の外観を示した図である。図１を参照して、電子機器１は、液晶ディスプレイ２０と、複数の操作キー１５とを備える。電子機器１は、携帯型電話機、ＰＤＡ（Personal　Digital　Assistants）、タブレット端末、電子辞書、電子ブックリーダ等の携帯端末である。 FIG. 1 is a diagram showing the external appearance of the electronic device 1.

　電子機器１は、２次元画像と３次元画像とを液晶ディスプレイ２０に表示可能な機器である。以下では、電子機器１が、パララックスバリヤ方式で３次元画像を表示する構成であるとして説明する。なお、３次元画像を表示する方法は、パララックススバリア方式に限定されるものではない。電子機器１は、たとえば、アナグリフ方式、偏光板方式、液晶アクティブシャッターメガネ方式で３次元画像を表示する構成であってもよい。 The electronic device 1 is a device that can display a two-dimensional image and a three-dimensional image on the liquid crystal display 20. In the following description, it is assumed that the electronic device 1 is configured to display a three-dimensional image by the parallax barrier method. Note that the method of displaying a three-dimensional image is not limited to the parallax barrier method. The electronic device 1 may be configured to display a three-dimensional image by, for example, an anaglyph method, a polarizing plate method, or a liquid crystal active shutter glasses method.
　図２は、液晶ディスプレイ２０の構造を説明するための図である。
　図２（ａ）は、液晶ディスプレイ２０の概略構造を表した図である。図２（ａ）を参照して、液晶ディスプレイ２０は、液晶パネル２１０と、バックライト２３０とを備える。液晶パネル２１０は、バックライト２３０の上側（Ｚ軸負方向側）に、バックライト２３０と平行となるように配置される。 FIG. 2 is a diagram for explaining the structure of the liquid crystal display 20.
FIG. 2A is a diagram showing a schematic structure of the liquid crystal display 20. With reference to FIG. 2A, the liquid crystal display 20 includes a liquid crystal panel 210 and a backlight 230. The liquid crystal panel 210 is disposed on the upper side (Z-axis negative direction side) of the backlight 230 so as to be parallel to the backlight 230.
　図２（ｂ）は、バックライト２３０の概略構造を表した図である。図２（ｂ）を参照して、バックライト２３０は、タンデム型のバックライトである。バックライト２３０は、基板２３１と、複数のＬＥＤ（Light　Emitting　Diode）２３２と、複数の導光板２３３とを備える。各ＬＥＤ２３２および各導光板２３３は、基板２３１上に、マトリクス状に配置されている。１つのＬＥＤ２３２と、１つの導光板２３３とが対になっている。また、複数のＬＥＤ２３２は、液晶パネル２１０に沿って平面的に配されている。 FIG. 2B is a diagram showing a schematic structure of the backlight 230. Referring to FIG. 2B, the backlight 230 is a tandem backlight. The backlight 230 includes a substrate 231, a plurality of LEDs (Light Emitting Diodes) 232, and a plurality of light guide plates 233. Each LED 232 and each light guide plate 233 are arranged in a matrix on the substrate 231. One LED 232 and one light guide plate 233 are paired. The plurality of LEDs 232 are arranged in a plane along the liquid crystal panel 210.
　図２（ｃ）は、図２（ｂ）のII－II線矢視断面図である。図２（ｃ）を参照して、各導光板２３３は、導光部と発光部とを備える。ＬＥＤ２３２から出射した光は、導光部を通過する。導光部を通過した光は、発光部から液晶パネル２１０方向へ略均一な光として出射する。 FIG. 2 (c) is a cross-sectional view taken along line II-II in FIG. 2 (b). Referring to FIG. 2C, each light guide plate 233 includes a light guide part and a light emitting part. The light emitted from the LED 232 passes through the light guide unit. The light that has passed through the light guide part is emitted as substantially uniform light from the light emitting part toward the liquid crystal panel 210.
　電子機器１は、各ＬＥＤ２３２が出射する光の光量を、３次元表示をするオブジェクトの飛び出し量および引っ込み量に応じて制御する。以下、当該制御の詳細について説明する。 The electronic device 1 controls the amount of light emitted from each LED 232 according to the amount of protrusion and the amount of retraction of an object that performs three-dimensional display. Hereinafter, details of the control will be described.
　図３は、電子機器１で行なわれる処理の概要を説明するための図である。図３（ａ）は、オブジェクトの飛び出し量および引っ込み量と、ＬＥＤ２３２が照射する光の光量との関係を表したグラフである。図３（ｂ）は、１枚の３Ｄ画像に含まれる複数のオブジェクトの例と、右目用画像と左目用画像とのズレ量と、飛び出し量と、引っ込み量との関係を表した図である。図３（ｃ）は、上記複数のオブジェクトを液晶ディスプレイ２０に表示した場合に、ユーザの眼に映る画像を表した図である。 FIG. 3 is a diagram for explaining an outline of processing performed in the electronic device 1. FIG. 3A is a graph showing the relationship between the amount of protrusion and the amount of retraction of the object and the amount of light emitted from the LED 232. FIG. 3B is a diagram illustrating a relationship between an example of a plurality of objects included in one 3D image, a shift amount between the right-eye image and the left-eye image, a pop-out amount, and a retraction amount. . FIG. 3C is a diagram showing an image that appears to the user's eyes when the plurality of objects are displayed on the liquid crystal display 20.
　図３（ａ）を参照して、グラフの曲線は、飛び出し量が多くなるほど、光量が多くなることを表している。また、当該曲線は、引っ込み量が多くなるほど、光量が少なくなることを表している。なお、電子機器１は、飛び出し量および引っ込み量と光量との関係を、離散的なデータとして記憶している。 Referring to FIG. 3A, the curve of the graph indicates that the amount of light increases as the pop-out amount increases. Moreover, the said curve represents that light quantity decreases, so that the amount of retraction increases. The electronic device 1 stores the relationship between the amount of protrusion and the amount of retraction and the amount of light as discrete data.
　電子機器１は、図３（ａ）に示すような飛び出し量および引っ込み量と光量との関係（上記の離散的なデータ）に基づき、オブジェクトの飛び出し量が大きい場合、当該オブジェクトを表示する液晶パネル２１０の表示領域に対応するＬＥＤ２３２の光量を、基準となる光量Ｌｓよりも多くする。より詳しくは、電子機器１は、オブジェクトの飛び出し量が大きいほど、多くの光量の光を、当該オブジェクトに対応するＬＥＤ２３２から照射させる。 The electronic device 1 is a liquid crystal panel that displays an object when the amount of protrusion of the object is large based on the relationship between the amount of protrusion and the amount of retraction and the amount of light (discrete data above) as shown in FIG. The light quantity of the LED 232 corresponding to the display area 210 is made larger than the reference light quantity Ls. More specifically, the electronic device 1 irradiates a larger amount of light from the LED 232 corresponding to the object as the amount of protrusion of the object increases.
　なお、基準となる光量Ｌｓは、デフォルトで定められている値、またはユーザの操作により設定された値である。電子機器１は、３次元表示されないオブジェクト（飛び出しも引っ込みもしないオブジェクト）に対しては、光量Ｌｓの光を照射する。また、電子機器１は、オブジェクトの座標に基づき、対応するＬＥＤ２３２を判定する。電子機器１は、オブジェクトの外形を含む表示領域に対応する１つ以上のＬＥＤ２３２を、当該オブジェクトに対応するＬＥＤ２３２と判定する。 Note that the reference light amount Ls is a value determined by default or a value set by a user operation. The electronic device 1 irradiates an object that is not three-dimensionally displayed (an object that neither jumps out nor retracts) with a light amount Ls. Also, the electronic device 1 determines the corresponding LED 232 based on the coordinates of the object. The electronic device 1 determines one or more LEDs 232 corresponding to the display area including the outer shape of the object as the LEDs 232 corresponding to the object.
　また、電子機器１は、オブジェクトの引っ込み量が大きい場合、当該オブジェクトを表示する液晶パネル２１０の表示領域に対応するＬＥＤ２３２の光量を、基準となる光量Ｌｓよりも少なくする。より詳しくは、電子機器１は、オブジェクトの引っ込み量が大きいほど、少ない光量の光を、当該オブジェクトに対応するＬＥＤ２３２から照射させる。 Further, when the amount of retraction of the object is large, the electronic device 1 makes the light amount of the LED 232 corresponding to the display area of the liquid crystal panel 210 displaying the object smaller than the reference light amount Ls. More specifically, the electronic device 1 causes the LED 232 corresponding to the object to emit a smaller amount of light as the amount of retraction of the object is larger.
　図３（ｂ）を参照して、「人物」についての右目用画像と左目用画像とのズレ量が“＋Ｄ１”であり、「車」についての右目用画像と左目用画像とのズレ量が“＋Ｄ２”（ただし、Ｄ２＜Ｄ１）であり、「山」についての右目用画像と左目用画像とのズレ量が“０”であり、「太陽」についての右目用画像と左目用画像とのズレ量が“－Ｄ３”である。なお、ズレ量についての“＋”の記号は、オブジェクトが飛び出す場合のズレ量を表している。また、ズレ量についての“－”の記号は、オブジェクトが引っ込む場合のズレ量を表している。 Referring to FIG. 3B, the amount of deviation between the right-eye image and the left-eye image for “person” is “+ D1”, and the amount of deviation between the right-eye image and the left-eye image for “car” is “+ D2” (where D2 <D1), the amount of deviation between the right-eye image and the left-eye image for “mountain” is “0”, and the right-eye image and the left-eye image for “sun” The amount of deviation is “−D3”. Note that the symbol “+” regarding the amount of deviation represents the amount of deviation when the object pops out. Further, the symbol “−” regarding the amount of deviation represents the amount of deviation when the object is retracted.
　また、「人物」については、“＋Ｄ１”のズレにより飛び出し量が“Ｖ１”となる。「車」については、“＋Ｄ２”のズレにより飛び出し量が“Ｖ２”（ただし、Ｖ２＜Ｖ１）となる。「山」については、飛び出しも、引っ込みもしない。「太陽」については、“－Ｄ３”のズレにより引っ込み量が“Ｖ３”となる。 For “person”, the pop-out amount becomes “V1” due to the shift of “+ D1”. As for “car”, the pop-out amount becomes “V2” (where V2 <V1) due to the deviation of “+ D2”. For the “mountains”, neither jump out nor retract. For the “sun”, the amount of retraction becomes “V3” due to the deviation of “−D3”.
　なお、上記飛び出し量および引っ込み量は、液晶パネル２１０から予め定められた距離で或るユーザがオブジェクトを見たときの飛び出し量である。なお、飛び出し量および引っ込み量は、ユーザの両瞳孔の間隔、および瞳孔と液晶パネル２１０との距離により変化する。 Note that the pop-out amount and the retraction amount are the pop-out amounts when a certain user views the object at a predetermined distance from the liquid crystal panel 210. Note that the amount of protrusion and the amount of retraction vary depending on the distance between the pupils of the user and the distance between the pupil and the liquid crystal panel 210.
　図３（ｃ）を参照して、人物を表したオブジェクト９２１は飛び出し量がＶ１（図３（ｂ）参照）であるため、電子機器１は、オブジェクト９２１を表示する液晶パネル２１０の表示領域に対応するＬＥＤ２３２の光量を、基準となる光量Ｌｓよりも多い光量Ｌ１（図３（ａ）参照）とする。一方、車を表したオブジェクト９２２は飛び出し量がＶ２（図３（ｂ）参照）であるため、電子機器１は、オブジェクト９２２を表示する液晶パネル２１０の表示領域に対応するＬＥＤ２３２の光量を、基準となる光量Ｌｓよりも多い光量Ｌ２（図３（ａ）参照）とする。 Referring to FIG. 3C, since the object 921 representing the person has a pop-out amount V1 (see FIG. 3B), the electronic apparatus 1 displays the display area of the liquid crystal panel 210 that displays the object 921. The light amount of the corresponding LED 232 is set to a light amount L1 (see FIG. 3A) that is larger than the reference light amount Ls. On the other hand, since the object 922 representing the vehicle has a pop-out amount V2 (see FIG. 3B), the electronic device 1 uses the light amount of the LED 232 corresponding to the display area of the liquid crystal panel 210 that displays the object 922 as a reference. The amount of light L2 is larger than the amount of light Ls (see FIG. 3A).
　また、太陽を表したオブジェクト９２４は引っ込み量がＶ３（図３（ｂ）参照）であるため、電子機器１は、オブジェクト９２４を表示する液晶パネル２１０の表示領域に対応するＬＥＤ２３２の光量を、基準となる光量Ｌｓよりも少ない光量Ｌ３（図３（ａ）参照）とする。なお、山を表したオブジェクト９２３は、飛び出しも引っ込みもしないため、電子機器１は、オブジェクト９２３を表示する液晶パネル２１０の表示領域に対応するＬＥＤ２３２の光量を、基準となる光量Ｌｓとする。 In addition, since the object 924 representing the sun has a retraction amount of V3 (see FIG. 3B), the electronic apparatus 1 uses the light amount of the LED 232 corresponding to the display area of the liquid crystal panel 210 displaying the object 924 as a reference. The amount of light L3 is smaller than the amount of light Ls (see FIG. 3A). Since the object 923 representing a mountain does not protrude or retract, the electronic apparatus 1 sets the light amount of the LED 232 corresponding to the display area of the liquid crystal panel 210 displaying the object 923 as the reference light amount Ls.
　以上のように、電子機器１は、飛び出した態様で表示させるオブジェクト９２２の画像に対して、基準となる光量よりも多くの光量の光を照射する。また、電子機器１は、オブジェクト９２２よりも飛び出し量の多いオブジェクト９２１の画像に対して、オブジェクト９２２の画像に対して照射する光の光量よりも多くの光量の光を照射させる。さらに、電子機器１は、引っ込んだ態様で表示させるオブジェクト９２４の画像に対して、基準となる光量よりも少ない光量の光を照射する。つまり、電子機器１は、飛び出し量が多いオブジェクトほど、照射する光の光量を多くし、引っ込み量が多いオブジェクトほど、照射する光の光量を少なくする。 As described above, the electronic device 1 irradiates the image of the object 922 displayed in a protruding manner with a light amount greater than the reference light amount. In addition, the electronic device 1 irradiates the image of the object 921, which has a larger amount of protrusion than the object 922, with a larger amount of light than the amount of light emitted to the image of the object 922. Furthermore, the electronic device 1 irradiates the image of the object 924 displayed in the retracted mode with a light amount smaller than the reference light amount. That is, the electronic device 1 increases the amount of light to be applied to an object with a larger amount of protrusion, and decreases the amount of light to be applied to an object with a larger amount of retraction.
　それゆえ、電子機器１は、３次元画像の明るさを３次元画像毎に設定可能となる。また、電子機器１は、バックライトの光量をオブジェクト毎に変更しない構成とは異なり、飛び出した態様で表示するオブジェクトを、飛び出し量に応じた態様で強調表示することができる。さらに、電子機器１は、引っ込んだ態様で表示するオブジェクトに対する光量を低下させるため、飛び出した態様で表示するオブジェクトを、より強調して表示することが可能となる。 Therefore, the electronic device 1 can set the brightness of the three-dimensional image for each three-dimensional image. Further, unlike the configuration in which the amount of light of the backlight is not changed for each object, the electronic device 1 can highlight an object to be displayed in a protruding manner in a manner corresponding to the protruding amount. Furthermore, since the electronic device 1 reduces the amount of light with respect to the object displayed in the retracted mode, the object displayed in the protruding mode can be displayed with more emphasis.
　したがって、ユーザは、飛び出し量の多いオブジェクトほど視認しやすくなり、引っ込み量の多いオブジェクトほど視認しにくくなる。 Therefore, the user can easily recognize the object with a larger amount of pop-up, and the object with a larger amount of retraction becomes less visible.
　以下、上述した処理を実行する電子機器１の具体的な構成について説明する。なお、電子機器１が３次元表示する画像は、静止画であっても、動画であってもよい。動画の場合には、１枚の静止画毎に、ＬＥＤ２３２の光量を変更する制御を行なう。 Hereinafter, a specific configuration of the electronic device 1 that performs the above-described processing will be described. Note that the image that the electronic device 1 displays three-dimensionally may be a still image or a moving image. In the case of a moving image, control is performed to change the light quantity of the LED 232 for each still image.
　図４は、電子機器１のハードウェア構成を表した図である。図４を参照して、電子機器１は、プログラムを実行するＣＰＵ（Central　Processing　Unit）１０と、データを不揮発的に格納するＲＯＭ（Read　Only　Memory）１１と、データを不揮発的に格納するＲＡＭ（Random　Access　Memory）１２と、フラッシュメモリ等の不揮発性メモリ１３と、画像処理用プロセッサ１４と、電子機器１のユーザによる指示の入力を受ける操作キー１５と、通信ＩＦ（interface）１６と、電源ユニット１７と、ズレ量測定モジュール１８と、３Ｄ（Dimension）表示用グラフィックエンジン１９と、液晶ディスプレイ２０と、スピーカ２１と、ＩＣ（Integrated　Circuit）カードリーダライタ２２と、データバス２３とを備える。また、液晶ディスプレイ２０は、液晶パネル２１０と、バックライト２３０と、ＬＣＤ（Liquid　Crystal　Display）コントローラ２２０と、バックライトコントローラ２４０とを備える。 FIG. 4 is a diagram showing a hardware configuration of the electronic device 1. Referring to FIG. 4, an electronic device 1 includes a CPU (Central Processing Unit) 10 that executes a program, a ROM (Read Only Memory) 11 that stores data in a nonvolatile manner, and a RAM that stores data in a nonvolatile manner ( Random Access Memory) 12, a non-volatile memory 13 such as a flash memory, an image processing processor 14, an operation key 15 for receiving an instruction input by a user of the electronic device 1, a communication IF (interface) 16, and a power supply unit 17, a deviation amount measurement module 18, a 3D (Dimension) display graphic engine 19, a liquid crystal display 20, a speaker 21, an IC (Integrated Circuit) card reader / writer 22, and a data bus 23. The liquid crystal display 20 includes a liquid crystal panel 210, a backlight 230, an LCD (Liquid Crystal Display) controller 220, and a backlight controller 240.
　不揮発性メモリ１３は、ＣＰＵ１０が実行するプログラム、各種データを格納している。また、不揮発性メモリ１３は、電子機器１が生成したデータ、電子機器１の外部装置から取得したデータ等の各種データを揮発的に格納する。 The nonvolatile memory 13 stores programs executed by the CPU 10 and various data. The non-volatile memory 13 stores various data such as data generated by the electronic device 1 and data acquired from an external device of the electronic device 1 in a volatile manner.
　画像処理用プロセッサ１４は、画像データを処理する専用のプロセッサである。通信ＩＦ１６は、他の装置と通信を行なうための用いられるインターフェースである。通信ＩＦ１６は、無線および／または有線にてデータを送信するための処理を行なう。電源ユニット１７は、各構成要素１０～１６、１８～２２に電力を供給する。スピーカ２１は、ＣＰＵ１０からの指令に応じて音を発生させる。 The image processing processor 14 is a dedicated processor for processing image data. The communication IF 16 is an interface used for communicating with other devices. The communication IF 16 performs processing for transmitting data wirelessly and / or by wire. The power supply unit 17 supplies power to each of the components 10 to 16 and 18 to 22. The speaker 21 generates a sound in response to a command from the CPU 10.
　ズレ量測定モジュール１８は、プロセッサとメモリとで構成される。当該メモリには、プログラム等が格納されている。ズレ量測定モジュール１８は、ＣＰＵ１０からの指令に応じて、右眼用画像データと左眼用画像データとから、それぞれオブジェクトを抽出する。当該オブジェクトの抽出は、従来知られている手法を用いる。ズレ量測定モジュール１８は、抽出した互いに対応するオブジェクト同士のズレ量（Ｘ座標およびＹ座標のズレ）を求める。具体例を挙げると、右眼用画像データに含まれる人物の画像と、左眼用画像データに含まれる人物の画像との、座標のズレを求める。図３（ｃ）の場合には、電子機器１は、横長の画像を表示するため、Ｙ座標方向のズレ量を求める。ズレ量測定モジュール１８は、測定したズレ量を、液晶ディスプレイ２０のバックライトコントローラ２４０に送る。 The deviation amount measurement module 18 includes a processor and a memory. A program or the like is stored in the memory. The deviation amount measurement module 18 extracts objects from the right-eye image data and the left-eye image data, respectively, in response to a command from the CPU 10. For extracting the object, a conventionally known method is used. The deviation amount measuring module 18 obtains the deviation amount (the deviation between the X coordinate and the Y coordinate) between the extracted objects corresponding to each other. As a specific example, a coordinate shift between a person image included in the right-eye image data and a person image included in the left-eye image data is obtained. In the case of FIG. 3C, the electronic device 1 obtains a shift amount in the Y coordinate direction in order to display a horizontally long image. The deviation amount measurement module 18 sends the measured deviation amount to the backlight controller 240 of the liquid crystal display 20.
　３Ｄ表示用グラフィックエンジン１９は、３次元画像を表示するための専用の画像処理エンジンである。３Ｄ表示用グラフィックエンジン１９は、右眼用画像データと左眼用画像データとから１枚の立体用画像データを生成する。３Ｄ表示用グラフィックエンジン１９は、生成した立体画像データをＬＣＤコントローラ２２０に送る。 The 3D display graphic engine 19 is a dedicated image processing engine for displaying a three-dimensional image. The 3D display graphic engine 19 generates one piece of stereoscopic image data from the right-eye image data and the left-eye image data. The 3D display graphic engine 19 sends the generated stereoscopic image data to the LCD controller 220.
　ＬＣＤコントローラ２２０は、液晶パネル２１０を駆動するための装置である。ＬＣＤコントローラ２２０は、立体画像データ等の画像データに基づいた画像を液晶パネル２１０に表示させるための種々の信号を液晶パネル２１０に送る。ＬＣＤコントローラ２２０は、どのタイミングで、どの立体画像データを表示させるのかを示す信号を、バックライトコントローラ２４０に送信する。 The LCD controller 220 is a device for driving the liquid crystal panel 210. The LCD controller 220 sends various signals to the liquid crystal panel 210 for causing the liquid crystal panel 210 to display an image based on image data such as stereoscopic image data. The LCD controller 220 transmits a signal indicating which stereoscopic image data is displayed at which timing to the backlight controller 240.
　バックライトコントローラ２４０は、ズレ量測定モジュール１８が測定したズレ量を取得する。なお、電子機器１が動画を表示する場合には、動画を構成する静止画毎のズレ量を順次または一度に取得する。当該ズレ量は、立体画像データとの対応付けがなされている。 The backlight controller 240 acquires the amount of deviation measured by the deviation amount measurement module 18. When the electronic device 1 displays a moving image, the shift amount for each still image constituting the moving image is acquired sequentially or at a time. The amount of deviation is associated with stereoscopic image data.
　バックライトコントローラ２４０は、ＬＣＤコントローラ２２０から上記信号を受信する。バックライトコントローラ２４０は、ズレ量測定モジュール１８により測定されたズレ量と上記受信した信号とに基づき、表示される立体画像毎に、各ＬＥＤ２３２の光量を制御する。 The backlight controller 240 receives the signal from the LCD controller 220. The backlight controller 240 controls the amount of light of each LED 232 for each stereoscopic image to be displayed based on the amount of deviation measured by the amount of deviation measurement module 18 and the received signal.
　各構成要素１０～２２は、相互にデータバス２３によって接続されている。ＩＣカードリーダライタ２２には、メモリカード２２０１が装着される。 The components 10 to 22 are connected to each other by a data bus 23. A memory card 2201 is attached to the IC card reader / writer 22.
　電子機器１における処理は、各ハードウェアおよびＣＰＵ１０およびズレ量測定モジュール１８により実行されるソフトウェアによって実現される。このようなソフトウェアは、不揮発性メモリ１３およびズレ量測定モジュール１８に予め記憶されている場合がある。また、ソフトウェアは、メモリカード２２０１その他の記憶媒体に格納されて、プログラムプロダクトとして流通している場合もある。あるいは、ソフトウェアは、いわゆるインターネットに接続されている情報提供事業者によってダウンロード可能なプログラムプロダクトとして提供される場合もある。このようなソフトウェアは、ＩＣカードリーダライタ２２その他の読取装置によりその記憶媒体から読み取られて、あるいは、通信ＩＦ１６を介してダウンロードされた後、不揮発性メモリ１３に一旦格納される。そのソフトウェアは、ＣＰＵ１０によって不揮発性メモリ１３から読み出され、さらに不揮発性メモリ１３またはズレ量測定モジュール１８に実行可能なプログラムの形式で格納される。ＣＰＵ１０またはズレ量測定モジュール１８は、そのプログラムを実行する。 The processing in the electronic device 1 is realized by each hardware and software executed by the CPU 10 and the deviation measurement module 18. Such software may be stored in advance in the nonvolatile memory 13 and the deviation amount measuring module 18. Further, the software may be stored in a memory card 2201 or other storage medium and distributed as a program product. Alternatively, the software may be provided as a program product that can be downloaded by an information provider connected to the so-called Internet. Such software is read from the storage medium by the IC card reader / writer 22 or other reading device, or downloaded via the communication IF 16 and then temporarily stored in the nonvolatile memory 13. The software is read from the nonvolatile memory 13 by the CPU 10 and further stored in the form of an executable program in the nonvolatile memory 13 or the deviation amount measuring module 18. The CPU 10 or the deviation amount measurement module 18 executes the program.
　同図に示される電子機器１を構成する各構成要素は、一般的なものである。したがって、本発明の本質的な部分は、ズレ量測定モジュール１８、不揮発性メモリ１３、メモリカード２２０１その他の記憶媒体に格納されたソフトウェア、あるいはネットワークを介してダウンロード可能なソフトウェアであるともいえる。なお、電子機器１の各ハードウェア（ズレ量測定モジュール１８を除く）の動作は周知であるので、詳細な説明は繰り返さない。 Each component constituting the electronic device 1 shown in the figure is a general one.

　図５は、電子機器１の機能ブロック図である。図５を参照して、電子機器１は、液晶パネル２１０と、バックライト２３０と、制御部２５０とを備える。制御部２５０は、表示制御部２５１と、バックライト制御部２５２とを備える。 FIG. 5 is a functional block diagram of the electronic device 1. Referring to FIG. 5, electronic device 1 includes a liquid crystal panel 210, a backlight 230, and a control unit 250. The control unit 250 includes a display control unit 251 and a backlight control unit 252.
　制御部２５０は、電子機器１の動作を制御する。表示制御部２５１は、液晶パネル２１０に画像を表示させる。バックライト制御部２５２は、バックライト２３０における複数のＬＥＤ２３２の光量を制御する。以下、制御部２５０による処理の詳細について説明する。 The control unit 250 controls the operation of the electronic device 1. The display control unit 251 displays an image on the liquid crystal panel 210. The backlight control unit 252 controls the light amount of the plurality of LEDs 232 in the backlight 230. Details of the processing by the control unit 250 will be described below.
　制御部２５０は、バックライト２３０が照射する光の光量を制御する。制御部２５０は、液晶パネル２１０が飛び出した態様でオブジェクトを表示する場合、当該オブジェクトを表示する表示領域に対して照射する光の光量を、基準となる光量Ｌｓよりも多くする。また、制御部２５０は、液晶パネル２１０が引っ込んだ態様でオブジェクトを表示する場合には、当該オブジェクトを表示する表示領域に対して照射する光の光量を、基準となる光量Ｌｓよりも少なくする。 The control unit 250 controls the amount of light emitted from the backlight 230. When the object is displayed in a manner in which the liquid crystal panel 210 protrudes, the control unit 250 increases the amount of light emitted to the display area for displaying the object, more than the reference light amount Ls. In addition, when the object is displayed in a manner in which the liquid crystal panel 210 is retracted, the control unit 250 reduces the amount of light applied to the display area displaying the object to be smaller than the reference light amount Ls.
　詳しくは、制御部２５０は、液晶パネル２１０が飛び出した態様でオブジェクトを表示する場合には、表示領域に対して、当該オブジェクトの飛び出し量が大きいほど多くの光量の光を、バックライト２３０に照射させる。制御部２５０は、液晶パネル２１０が引っ込んだ態様でオブジェクトを表示する場合には、表示領域に対して、当該オブジェクトの引っ込み量が大きいほど少ない光量の光を、バックライト２３０に照射させる。具体的には、制御部２５０は、バックライト２３０に含まれる複数のＬＥＤ２３２のうちオブジェクトを表示する表示領域に対して光を照射するＬＥＤ２３２を判定し、当該ＬＥＤ２３２が発光する光の光量を制御する。 Specifically, when the object is displayed with the liquid crystal panel 210 protruding, the control unit 250 irradiates the backlight 230 with a larger amount of light as the amount of protrusion of the object increases with respect to the display area. Let When the object is displayed in a manner in which the liquid crystal panel 210 is retracted, the control unit 250 causes the backlight 230 to irradiate the backlight 230 with a smaller amount of light as the amount of the object retracted is larger. Specifically, the control unit 250 determines the LED 232 that emits light to the display area that displays the object among the plurality of LEDs 232 included in the backlight 230, and controls the amount of light emitted by the LED 232. .
　また、制御部２５０は、液晶パネル２１０が飛び出した態様で複数のオブジェクトを表示する場合には、各オブジェクトの各表示領域に対して、各オブジェクトの飛び出し量に対応した光量の光を、バックライト２３０に照射させる。また、制御部２５０は、液晶パネル２１０が引っ込んだ態様で複数のオブジェクトを表示する場合には、各オブジェクトの各表示領域に対して、各オブジェクトの引っ込み量に対応した光量の光を、バックライト２３０に照射させる。 In addition, when displaying a plurality of objects in a manner in which the liquid crystal panel 210 protrudes, the control unit 250 transmits a light amount of light corresponding to the amount of protrusion of each object to each display area of each object. 230 is irradiated. In addition, when displaying a plurality of objects in a manner in which the liquid crystal panel 210 is retracted, the control unit 250 applies a light amount of light corresponding to the amount of retraction of each object to each display area of each object. 230 is irradiated.
　図６は、各オブジェクト９２１，９２２，９２４の表示領域に対応する導光板２３３を説明するための図である。図６を参照して、右下の実線で示した１０個の導光板２３３が、オブジェクト９２１に対応する。左下の実線で示した１３個の導光板２３３が、オブジェクト９２２に対応する。右上の実線で示した９個の導光板２３３が、オブジェクト９２４に対応する。 FIG. 6 is a diagram for explaining the light guide plate 233 corresponding to the display area of each object 921, 922, 924. Referring to FIG. 6, ten light guide plates 233 indicated by a solid line at the lower right correspond to the object 921. Thirteen light guide plates 233 indicated by a solid line in the lower left correspond to the object 922. Nine light guide plates 233 indicated by a solid line in the upper right correspond to the object 924.
　導光板２３３とＬＥＤとは１対１に対応するため、図６は、複数のＬＥＤ２３２のうちオブジェクトを表示する表示領域に対して光を照射するＬＥＤ２３２を示した図であるとも言える。 Since the light guide plate 233 and the LEDs correspond one-to-one, FIG. 6 can be said to be a diagram showing the LEDs 232 that irradiate light to the display area for displaying the object among the plurality of LEDs 232.
　図７は、電子機器１における処理の流れを示したフローチャートである。図７を参照して、ステップＳ２において、ズレ量測定モジュール１８は、ＣＰＵ１０からの指令に応じて、右眼用画像データと左眼用画像データとから、それぞれオブジェクトを抽出する。ステップＳ４において、ズレ量測定モジュール１８は、抽出した互いに対応するオブジェクト同士のズレ量を求める。ステップＳ６において、バックライトコントローラ２４０は、各オブジェクトの液晶パネル２１０における表示領域に対応するＬＥＤ２３２の光量を、ズレ量に基づき算出する。ステップＳ８において、バックライトコントローラ２４０は、オブジェクトの表示タイミングに合わせて、算出した光の光量を当該オブジェクトに対応するＬＥＤ２３２から照射させる。 FIG. 7 is a flowchart showing the flow of processing in the electronic device 1. Referring to FIG. 7, in step S <b> 2, deviation amount measurement module 18 extracts objects from right-eye image data and left-eye image data in response to a command from CPU 10. In step S4, the deviation amount measurement module 18 obtains the deviation amount between the extracted objects corresponding to each other. In step S6, the backlight controller 240 calculates the light quantity of the LED 232 corresponding to the display area of each object on the liquid crystal panel 210, based on the amount of deviation. In step S8, the backlight controller 240 irradiates the calculated amount of light from the LED 232 corresponding to the object in accordance with the display timing of the object.

Note that the method of displaying a three-dimensional image is not limited to the parallax barrier method. The electronic apparatus 1A may be configured to display a three-dimensional image by, for example, an anaglyph method, a polarizing plate method, or a liquid crystal active shutter glasses method.
　図９は、液晶ディスプレイ２０Ａの構造を説明するための図である。
　図９（ａ）は、液晶ディスプレイ２０Ａの概略構造を表した図である。図９（ａ）を参照して、液晶ディスプレイ２０Ａは、液晶パネル２１０と、液晶シャッタ２７０と、バックライト２９０とを備える。液晶パネル２１０は、液晶シャッタ２７０の上側（Ｚ軸負方向側）に、液晶シャッタ２７０と平行となるように配置される。また、液晶シャッタ２７０は、バックライト２９０の上側に、バックライト２９０と平行となるように配置される。本実施の形態では、液晶シャッタ２７０とバックライト２９０とにより、液晶パネル２１０に対して光を照射する。 FIG. 9 is a diagram for explaining the structure of the liquid crystal display 20A.
FIG. 9A is a diagram showing a schematic structure of the liquid crystal display 20A. Referring to FIG. 9A, the liquid crystal display 20A includes a liquid crystal panel 210, a liquid crystal shutter 270, and a backlight 290. The liquid crystal panel 210 is disposed on the upper side (Z-axis negative direction side) of the liquid crystal shutter 270 so as to be parallel to the liquid crystal shutter 270. The liquid crystal shutter 270 is disposed above the backlight 290 so as to be parallel to the backlight 290. In the present embodiment, light is emitted to liquid crystal panel 210 by liquid crystal shutter 270 and backlight 290.
　図９（ｂ）は、液晶パネル２１０と液晶シャッタ２７０との画素の配置関係を表した図である。図９（ｂ）を参照して、液晶パネル２１０の画素数と液晶シャッタ２７０の画素数とは、Ｘ軸方向およびＹ軸方向において同じである。また、液晶パネル２１０の各画素と、液晶シャッタ２７０の各画素のサイズは同じである。 FIG. 9B is a diagram showing a pixel arrangement relationship between the liquid crystal panel 210 and the liquid crystal shutter 270. Referring to FIG. 9B, the number of pixels of the liquid crystal panel 210 and the number of pixels of the liquid crystal shutter 270 are the same in the X-axis direction and the Y-axis direction. Further, the size of each pixel of the liquid crystal panel 210 and the size of each pixel of the liquid crystal shutter 270 are the same.
　詳しくは、液晶パネル２１０における画素Ｐ（ｉ，ｊ）のＸＹ座標が、液晶シャッタ２７０における画素Ｑ（ｉ，ｊ）のＸＹ座標と一致する。なお、１≦ｉ≦ｍであり、１≦ｊ≦ｎである。また、ｍは、Ｘ軸方向の画素数を表す自然数であり、ｎは、Ｙ軸方向の画素数を表す自然数である。 Specifically, the XY coordinates of the pixel P (i, j) on the liquid crystal panel 210 coincide with the XY coordinates of the pixel Q (i, j) on the liquid crystal shutter 270. Note that 1 ≦ i ≦ m and 1 ≦ j ≦ n. M is a natural number representing the number of pixels in the X-axis direction, and n is a natural number representing the number of pixels in the Y-axis direction.
　図９（ｃ）は、バックライト２９０の概略構成を表した図である。図９（ｃ）を参照して、バックライト２９０は、エッジライト方式のバックライトである。バックライト２９０は、ＬＥＤアレイ２９１と、導光板２９２とを備える。ＬＥＤ２９１から出射した光は、導光板２９２の端面に入射する。導光板２９２に入射した光は、導光板２９２の主表面２９２１から略均一光として、液晶シャッタ２７０方向に出射する。 FIG. 9C is a diagram illustrating a schematic configuration of the backlight 290. Referring to FIG. 9C, the backlight 290 is an edge light type backlight. The backlight 290 includes an LED array 291 and a light guide plate 292. The light emitted from the LED 291 enters the end surface of the light guide plate 292. The light incident on the light guide plate 292 exits from the main surface 2921 of the light guide plate 292 as substantially uniform light in the direction of the liquid crystal shutter 270.
　電子機器１Ａは、液晶シャッタ２７０による光の透過率を制御することにより、オブジェクトを表示する表示領域に照射する光の光量を制御する。具体的には、電子機器１Ａは、オブジェクトを表示する液晶パネル２１０の画素に対応する、液晶シャッタ２７０の画素における光の透過率を制御する。なお、電子機器１Ａは、透過率の制御を、液晶シャッタ２７０の液晶に印加する電圧により行なう。 The electronic apparatus 1A controls the light transmittance of the display area where the object is displayed by controlling the light transmittance of the liquid crystal shutter 270. Specifically, the electronic apparatus 1A controls the light transmittance of the pixels of the liquid crystal shutter 270 corresponding to the pixels of the liquid crystal panel 210 that displays the object. Note that the electronic apparatus 1 </ b> A controls the transmittance by a voltage applied to the liquid crystal of the liquid crystal shutter 270.
　図１０は、オブジェクトの飛び出し量および引っ込み量と、液晶シャッタ２７０の液晶の透過率との対応関係を表した図である。なお、透過率は光量に比例するため、図１０は、オブジェクトの飛び出し量および引っ込み量と、液晶シャッタ２７０を透過する光の光量との対応関係を表した図であるとも言える。 FIG. 10 is a diagram showing a correspondence relationship between the amount of protrusion and retraction of the object and the liquid crystal transmittance of the liquid crystal shutter 270. Since the transmittance is proportional to the amount of light, it can be said that FIG. 10 is a diagram showing the correspondence between the amount of protrusion and retraction of the object and the amount of light transmitted through the liquid crystal shutter 270.
　図１０を参照して、グラフの曲線は、飛び出し量が多くなるほど、透過率が大きくなることを表している。また、当該曲線は、引っ込み量が多くなるほど、透過率が小さくなることを表している。なお、電子機器１Ａは、飛び出し量および引っ込み量と透過率との関係を、離散的なデータとして記憶している。 Referring to FIG. 10, the curve of the graph indicates that the transmittance increases as the pop-out amount increases. Moreover, the said curve represents that the transmittance | permeability becomes small, so that the amount of retraction increases. Note that the electronic device 1A stores the relationship between the pop-out amount, the retract amount, and the transmittance as discrete data.
　電子機器１Ａは、図１０に示すような飛び出し量および引っ込み量と透過率との関係に基づき、オブジェクトの飛び出し量が大きい場合、当該オブジェクトを表示する液晶パネル２１０の表示領域に対応する液晶シャッタの画素の透過率を、基準となる透過率Ｔｓよりも大きくする。より詳しくは、電子機器１Ａは、オブジェクトの飛び出し量が大きいほど、多くの光量の光を、当該オブジェクトに対応する液晶シャッタ２７０の画素から透過させる。 When the amount of popping out of an object is large based on the relationship between the pop-out amount and the retracting amount and the transmittance as shown in FIG. 10, the electronic device 1A has a liquid crystal shutter corresponding to the display area of the liquid crystal panel 210 that displays the object. The transmittance of the pixel is set larger than the reference transmittance Ts. More specifically, the electronic apparatus 1A transmits a larger amount of light from the pixels of the liquid crystal shutter 270 corresponding to the object as the amount of protrusion of the object is larger.
　なお、基準となる透過率Ｔｓは、デフォルトで定められている値、またはユーザの操作により設定された値である。電子機器１Ａは、３次元表示されないオブジェクト（飛び出しも引っ込みもしないオブジェクト）に対しては、液晶シャッタ２７０における画素の透過率を透過率Ｔｓとする。また、電子機器１Ａは、オブジェクトの座標に基づき、対応する液晶シャッタ２７０の画素を判定する。液晶パネル２１０の画素と液晶シャッタ２７０の画素とは、図９（ｂ）に示したとおり、１対１に対応している。このため、電子機器１Ａは、オブジェクトの表示に用いた画素に対応する液晶シャッタ２７０の画素の透過率を変更する。 The reference transmittance Ts is a value determined by default or a value set by a user operation. The electronic device 1A sets the transmittance of the pixels in the liquid crystal shutter 270 to the transmittance Ts for an object that is not three-dimensionally displayed (an object that does not pop out or retract). Also, the electronic apparatus 1A determines the corresponding pixel of the liquid crystal shutter 270 based on the coordinates of the object. The pixels of the liquid crystal panel 210 and the pixels of the liquid crystal shutter 270 have a one-to-one correspondence as shown in FIG. 9B. For this reason, the electronic apparatus 1A changes the transmittance of the pixel of the liquid crystal shutter 270 corresponding to the pixel used for displaying the object.
　また、電子機器１Ａは、オブジェクトの引っ込み量が大きい場合、当該オブジェクトを表示する液晶パネル２１０の表示領域に対応する液晶シャッタの画素の透過率を、基準となる透過率Ｔｓよりも小さくする。より詳しくは、電子機器１Ａは、オブジェクトの引っ込み量が大きいほど、少ない光量の光を、当該オブジェクトに対応する液晶シャッタ２７０の画素から透過させる。 Further, when the amount of retraction of the object is large, the electronic device 1A makes the transmittance of the liquid crystal shutter pixels corresponding to the display area of the liquid crystal panel 210 displaying the object smaller than the reference transmittance Ts. More specifically, the electronic device 1A transmits a smaller amount of light from the pixels of the liquid crystal shutter 270 corresponding to the object as the amount of retraction of the object is larger.
　図１１は、電子機器１Ａのハードウェア構成を表した図である。図１１を参照して、電子機器１Ａは、ＣＰＵ１０と、ＲＯＭ１１と、ＲＡＭ１２と、不揮発性メモリ１３と、画像処理用プロセッサ１４と、操作キー１５と、通信ＩＦ１６と、電源ユニット１７と、ズレ量測定モジュール１８と、３Ｄ表示用グラフィックエンジン１９と、液晶ディスプレイ２０Ａと、スピーカ２１と、ＩＣカードリーダライタ２２と、データバス２３とを備える。このように、電子機器１Ａが液晶ディスプレイ２０Ａを備える点において、液晶ディスプレイ２０を備える実施の形態１の電子機器１と異なる。 FIG. 11 is a diagram illustrating a hardware configuration of the electronic apparatus 1A. Referring to FIG. 11, electronic device 1A includes CPU 10, ROM 11, RAM 12, nonvolatile memory 13, image processing processor 14, operation key 15, communication IF 16, power supply unit 17, and amount of deviation.

As described above, the electronic device 1A includes the liquid crystal display 20A, which is different from the electronic device 1 according to the first embodiment including the liquid crystal display 20.

　バックライトコントローラ２４０Ａは、予め定められた光量の光を液晶シャッタ２７０に照射する。 The backlight controller 240A irradiates the liquid crystal shutter 270 with a predetermined amount of light.
　ＬＣＤコントローラ２２０Ａは、液晶パネル２１０を駆動するための装置である。ＬＣＤコントローラ２２０Ａは、立体画像データ等の画像データに基づいた画像を液晶パネル２１０に表示させるための種々の信号を液晶パネル２１０に送る。 The LCD controller 220A is a device for driving the liquid crystal panel 210. The LCD controller 220 </ b> A sends various signals to the liquid crystal panel 210 for causing the liquid crystal panel 210 to display an image based on image data such as stereoscopic image data.
　ＬＣＤコントローラ２２０Ａは、上記信号と同期をとって、液晶パネル２１０の表示する画像データと同じ画像データに基づき、液晶パネル２１０における各オブジェクトを表示する画素に対応する液晶シャッタ２７０の画素の透過率を変更する。具体的には、ＬＣＤコントローラ２２０Ａは、ズレ量測定モジュール１８が測定したズレ量に基づいて、透過率を変更する。 The LCD controller 220A synchronizes with the above signal, and based on the same image data as the image data displayed on the liquid crystal panel 210, the transmittance of the pixels of the liquid crystal shutter 270 corresponding to the pixels displaying each object on the liquid crystal panel 210. change. Specifically, the LCD controller 220A changes the transmittance based on the deviation amount measured by the deviation amount measurement module 18.
　各構成要素１０～１９，２０Ａ，２１，２２は、相互にデータバス２３によって接続されている。 The constituent elements 10 to 19, 20 A, 21, and 22 are connected to each other by the data bus 23.
　図１２は、電子機器１Ａの機能ブロック図である。図１２を参照して、電子機器１Ａは、液晶パネル２１０と、液晶シャッタ２７０と、バックライト２９０と、制御部２５０Ａとを備える。制御部２５０Ａは、表示制御部２５１Ａと、バックライト制御部２５２Ａと、シャッタ制御部２５３とを備える。なお、以下では、液晶シャッタ２７０とバックライト２９０とを含む構成を、「照明装置３００」と称する。 FIG. 12 is a functional block diagram of the electronic device 1A. Referring to FIG. 12, electronic apparatus 1A includes a liquid crystal panel 210, a liquid crystal shutter 270, a backlight 290, and a control unit 250A.

Hereinafter, a configuration including the liquid crystal shutter 270 and the backlight 290 is referred to as an “illuminating device 300”.
　制御部２５０Ａは、電子機器１Ａの動作を制御する。表示制御部２５１Ａは、液晶パネル２１０に画像を表示させる。また、表示制御部２５１Ａは、上述した同期をとるための信号をシャッタ制御部２５３に送る。 Control unit 250A controls the operation of electronic device 1A. The display control unit 251A displays an image on the liquid crystal panel 210. In addition, the display control unit 251A sends a signal for taking the synchronization described above to the shutter control unit 253.
　バックライト制御部２５２Ａは、バックライト２９０のオン・オフ等を制御する。また、バックライト制御部２５２Ａは、ユーザからの指示に応じて、光量を変更する。 The backlight control unit 252A controls on / off of the backlight 290 and the like. Further, the backlight control unit 252A changes the amount of light according to an instruction from the user.
　シャッタ制御部２５３は、表示制御部２５１Ａからの信号に基づき、液晶シャッタ２７０の動作を制御する。具体的には、シャッタ制御部２５３は、液晶シャッタ２７０における各画素の液晶に印加する電圧を制御する。 The shutter control unit 253 controls the operation of the liquid crystal shutter 270 based on the signal from the display control unit 251A. Specifically, the shutter control unit 253 controls the voltage applied to the liquid crystal of each pixel in the liquid crystal shutter 270.
　以下、制御部２５０Ａによる処理の詳細について説明する。
　制御部２５０Ａは、照明装置３００が照射する光の光量を制御する。制御部２５０Ａは、液晶パネル２１０が飛び出した態様でオブジェクトを表示する場合、当該オブジェクトを表示する表示領域に対して照射する光の光量を、液晶シャッタ２７０の透過率を制御することによって、基準となる光量よりも多くする。また、制御部２５０Ａは、液晶パネル２１０が引っ込んだ態様でオブジェクトを表示する場合には、当該オブジェクトを表示する表示領域に対して照射する光の光量を、液晶シャッタ２７０の透過率を制御することによって、基準となる光量よりも少なくする。 Details of the processing by the control unit 250A will be described below.
The controller 250A controls the amount of light emitted from the lighting device 300. When the object is displayed in a manner in which the liquid crystal panel 210 protrudes, the control unit 250A controls the transmittance of the liquid crystal shutter 270 to control the transmittance of the liquid crystal shutter 270. More than the amount of light that will be. In addition, when the object is displayed in a manner in which the liquid crystal panel 210 is retracted, the control unit 250A controls the transmittance of the liquid crystal shutter 270 with respect to the amount of light applied to the display area for displaying the object. To reduce the amount of light as a reference.
　詳しくは、制御部２５０Ａは、液晶パネル２１０が飛び出した態様でオブジェクトを表示する場合には、表示領域に対して、当該オブジェクトの飛び出し量が大きいほど多くの光量の光を、液晶シャッタ２７０から透過させる。制御部２５０Ａは、液晶パネル２１０が引っ込んだ態様でオブジェクトを表示する場合には、表示領域に対して、当該オブジェクトの引っ込み量が大きいほど少ない光量の光を、液晶シャッタ２７０から透過させる。具体的には、制御部２５０は、液晶シャッタ２７０に含まれる複数の画素のうちオブジェクトを表示する表示領域に対して光を透過する画素を画像データに基づき判定し、当該画素の透過率を制御する。 Specifically, when the object is displayed with the liquid crystal panel 210 protruding, the control unit 250A transmits a larger amount of light from the liquid crystal shutter 270 as the amount of protrusion of the object increases with respect to the display area. Let When the object is displayed in a state in which the liquid crystal panel 210 is retracted, the control unit 250A transmits a smaller amount of light from the liquid crystal shutter 270 to the display area as the object is retracted. Specifically, the control unit 250 determines, based on the image data, a pixel that transmits light to a display area that displays an object among a plurality of pixels included in the liquid crystal shutter 270, and controls the transmittance of the pixel. To do.
　また、制御部２５０Ａは、液晶パネル２１０が飛び出した態様で複数のオブジェクトを表示する場合には、各オブジェクトの各表示領域に対して、各オブジェクトの飛び出し量に対応した光量の光を、液晶シャッタ２７０から透過させる。また、制御部２５０は、液晶パネル２１０が引っ込んだ態様で複数のオブジェクトを表示する場合には、各オブジェクトの各表示領域に対して、各オブジェクトの引っ込み量に対応した光量の光を、液晶シャッタ２７０から透過させる。 In addition, when displaying a plurality of objects in a manner in which the liquid crystal panel 210 protrudes, the control unit 250A emits light of a light amount corresponding to the protrusion amount of each object to each display area of each object. Transmit through 270. In addition, when displaying a plurality of objects in a manner in which the liquid crystal panel 210 is retracted, the control unit 250 emits light of a light amount corresponding to the amount of retraction of each object to each display area of each object. Transmit through 270.
　図１３は、液晶シャッタ２７０の画素の透過率を説明するための図である。図１３（ａ）は、液晶パネル２１０にオブジェクト９２１，９２２，９２４を表示した状態を表した図である。なお、オブジェクト９２３については、飛び出しも引っ込みもしていないため、説明の便宜上、図示していない。図１３（ｂ）は、液晶シャッタ２７０における透過率を変更した画素の位置を説明するための図である。 FIG. 13 is a diagram for explaining the transmittance of the pixels of the liquid crystal shutter 270. FIG. 13A is a diagram showing a state in which the objects 921, 922, and 924 are displayed on the liquid crystal panel 210. FIG. Note that the object 923 is not shown for convenience of explanation because it does not protrude or retract. FIG. 13B is a diagram for explaining the position of the pixel whose transmittance in the liquid crystal shutter 270 is changed.
　図１３を参照して、電子機器１Ａは、オブジェクト９２１を表示している液晶パネル２１０の画素に対応する液晶シャッタ２７０の画素（つまり図形９２１ａに含まれる画素）の透過率Ｔ１を、基準となる透過率より高くする。 Referring to FIG. 13, electronic device 1 </ b> A is based on transmittance T <b> 1 of a pixel of liquid crystal shutter 270 (that is, a pixel included in graphic 921 a) corresponding to the pixel of liquid crystal panel 210 displaying object 921. Make it higher than the transmittance.
　また、電子機器１Ａは、オブジェクト９２２を表示している液晶パネル２１０の画素に対応する液晶シャッタ２７０の画素（つまり図形９２２ａに含まれる画素）の透過率Ｔ２を、基準となる透過率より高く、かつ透過率Ｔ１よりも低くする。 Further, the electronic apparatus 1A has a transmittance T2 of a pixel of the liquid crystal shutter 270 corresponding to a pixel of the liquid crystal panel 210 displaying the object 922 (that is, a pixel included in the graphic 922a) higher than a reference transmittance. In addition, the transmittance is set lower than T1.
　さらに、電子機器１Ａは、オブジェクト９２４を表示している液晶パネル２１０の画素に対応する液晶シャッタ２７０の画素（つまり図形９２４ａに含まれる画素）の透過率Ｔ３を、基準となる透過率より低くする。なお、Ｔ１＞Ｔ２＞Ｔ３＞０である。 Furthermore, the electronic apparatus 1A sets the transmittance T3 of the pixel of the liquid crystal shutter 270 corresponding to the pixel of the liquid crystal panel 210 displaying the object 924 (that is, the pixel included in the graphic 924a) to be lower than the reference transmittance. . Note that T1> T2> T3> 0.
　このように、電子機器１Ａは、飛び出した態様で表示させるオブジェクト９２２の画像に対して、基準となる光量よりも多くの光量の光を照射する。また、電子機器１Ａは、オブジェクト９２２よりも飛び出し量の多いオブジェクト９２１の画像に対して、オブジェクト９２２の画像に対して照射する光の光量よりも多くの光量の光を照射させる。さらに、電子機器１Ａは、引っ込んだ態様で表示させるオブジェクト９２４の画像に対して、基準となる光量よりも少ない光量の光を照射する。つまり、電子機器１は、飛び出し量が多いオブジェクトほど、照射する光の光量を多くし、引っ込み量が多いオブジェクトほど、照射する光の光量を少なくする。 As described above, the electronic apparatus 1A irradiates the image of the object 922 displayed in a protruding manner with a light amount greater than the reference light amount. In addition, the electronic apparatus 1 </ b> A irradiates the image of the object 921, which has a larger amount of protrusion than the object 922, with a larger amount of light than the amount of light emitted to the image of the object 922. Furthermore, the electronic apparatus 1A irradiates the image of the object 924 displayed in the retracted mode with a light amount smaller than a reference light amount. That is, the electronic device 1 increases the amount of light to be applied to an object with a larger amount of protrusion, and decreases the amount of light to be applied to an object with a larger amount of retraction.
　それゆえ、電子機器１Ａは、３次元画像の明るさを３次元画像毎に設定可能となる。また、電子機器１Ａは、バックライトの光量をオブジェクト毎に変更しない構成とは異なり、飛び出した態様で表示するオブジェクトを、飛び出し量に応じた態様で強調表示することができる。さらに、電子機器１Ａは、引っ込んだ態様で表示するオブジェクトに対する光量を低下させるため、飛び出した態様で表示するオブジェクトを、より強調して表示することが可能となる。 Therefore, the electronic device 1A can set the brightness of the three-dimensional image for each three-dimensional image. Further, unlike the configuration in which the backlight light amount is not changed for each object, the electronic apparatus 1A can highlight the object to be displayed in a protruding manner in a manner corresponding to the protruding amount. Furthermore, since the electronic device 1A reduces the amount of light with respect to the object to be displayed in the retracted mode, the object to be displayed in the protruding mode can be displayed with more emphasis.
　したがって、ユーザは、飛び出し量の多いオブジェクトほど視認しやすくなり、引っ込み量の多いオブジェクトほど視認しにくくなる。 Therefore, the user can easily recognize the object with a larger amount of pop-up, and the object with a larger amount of retraction becomes less visible.
　図１４は、電子機器１Ａにおける処理の流れを示したフローチャートである。図１４を参照して、ステップＳ１２において、ズレ量測定モジュール１８は、ＣＰＵ１０からの指令に応じて、右眼用画像データと左眼用画像データとから、それぞれオブジェクトを抽出する。ステップＳ１４において、ズレ量測定モジュール１８は、抽出した互いに対応するオブジェクト同士のズレ量を求める。ステップＳ１６において、ＬＣＤコントローラ２２０Ａは、各オブジェクトの液晶パネル２１０における表示領域に対応する液晶シャッタ２７０の画素の透過率を、ズレ量に基づき算出する。ステップＳ１８において、ＬＣＤコントローラ２２０Ａは、オブジェクトの表示タイミングに合わせて、算出した透過率に基づく光量の光を、液晶シャッタ２７０より透過させる。 FIG. 14 is a flowchart showing a flow of processing in the electronic apparatus 1A. Referring to FIG. 14, in step S <b> 12, deviation amount measurement module 18 extracts objects from right-eye image data and left-eye image data in response to a command from CPU 10. In step S14, the deviation amount measurement module 18 obtains the deviation amount between the extracted objects corresponding to each other. In step S16, the LCD controller 220A calculates the transmittance of the pixels of the liquid crystal shutter 270 corresponding to the display area of each object on the liquid crystal panel 210 based on the amount of deviation. In step S <b> 18, the LCD controller 220 </ b> A transmits light of a light amount based on the calculated transmittance through the liquid crystal shutter 270 in accordance with the display timing of the object.
