Description

表示システム、ディスプレイ装置、リモートコントローラ、およびディスプレイ装置の制御方法Display system, display device, remote controller, and display device control method
　本発明は、表示システム、ディスプレイ装置、リモートコントローラ、およびディスプレイ装置の制御方法に関する。 The present invention relates to a display system, a display device, a remote controller, and a display device control method.
　液晶ディスプレイ装置を初めとするディスプレイ装置は、表示パネルに表示された画像を斜め方向から視聴すると画質が劣化してしまうという不具合がある。そのため、近年、視聴者のいる方向に表示パネルの姿勢を調整する方法が検討されている。 Display devices such as a liquid crystal display device have a problem that image quality deteriorates when an image displayed on a display panel is viewed from an oblique direction. Therefore, in recent years, methods for adjusting the orientation of the display panel in the direction in which the viewer is present have been studied.
　表示パネルの姿勢を調整する方法として検討されているものには、例えば、ディスプレイ装置を遠隔操作するリモートコントローラに表示パネルの向きを調整するための方向キー（例えば、左キーおよび右キー）を設け、視聴者による方向キーの押下により表示パネルの姿勢を調整する方法がある。この方法によれば、視聴者により方向キーが押下されている間、リモートコントローラは、押下されている方向キーを示す制御信号を送信する。ディスプレイ装置は、リモートコントローラから送信されてきた制御信号を受光センサにより受信し、受信した制御信号が示す方向キーの方向に表示パネルを向ける。 For example, a remote controller that remotely controls a display device is provided with direction keys (for example, a left key and a right key) for adjusting the orientation of the display panel. There is a method of adjusting the orientation of the display panel by pressing the direction key by the viewer. According to this method, while the direction key is pressed by the viewer, the remote controller transmits a control signal indicating the pressed direction key. The display device receives the control signal transmitted from the remote controller by the light receiving sensor, and directs the display panel in the direction of the direction key indicated by the received control signal.
　また、特許文献１（特開２００８－２８８９６３号公報）では、複数の受光センサをディスプレイ装置の前面に設置する方法が検討されている。この方法によれば、ディスプレイ装置は、複数の受光センサによる制御信号の受信状態から制御信号が送信されてきた方向を検出し、その検出した方向に表示パネルを向ける。 Also, in Patent Document 1 (Japanese Patent Laid-Open No. 2008-288963), a method of installing a plurality of light receiving sensors on the front surface of a display device is examined. According to this method, the display device detects the direction in which the control signal is transmitted from the reception state of the control signal by the plurality of light receiving sensors, and directs the display panel in the detected direction.
特開２００８－２８８９６３号公報JP 2008-288963 A
　しかしながら、リモートコントローラに設けられた方向キーの押下により表示パネルの姿勢を調整する方法では、視聴者は表示パネルが希望の向きとなるように方向キーを操作して調整しなければならず、手間がかかるという課題があった。 However, in the method of adjusting the orientation of the display panel by pressing the direction key provided on the remote controller, the viewer must adjust the display panel by operating the direction key so that the display panel is in the desired direction.

　以下に、本発明を実施するための形態について図面を参照して説明する。 Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.
　図１は、本発明による一実施形態のディスプレイ装置が適用される表示システムを示す図である。 FIG. 1 is a diagram showing a display system to which a display device according to an embodiment of the present invention is applied.
　図１に示す表示システム１０は、リモートコントローラ１００と、ディスプレイ装置２００と、を具備する。 The display system 10 shown in FIG. 1 includes a remote controller 100 and a display device 200.
　リモートコントローラ１００は、ディスプレイ装置２００を遠隔操作するための種々の制御信号（赤外線信号）をディスプレイ装置２００に送信する。例えば、リモートコントローラ１００は、ディスプレイ装置２００の表示方向調整用キーが設けられており、表示方向調整用キーが押下されると、表示方向の調整が必要であることを示す方向調整用の制御信号を一定時間送信する。 The remote controller 100 transmits various control signals (infrared signals) for remotely operating the display device 200 to the display device 200. For example, the remote controller 100 is provided with a display direction adjustment key of the display device 200. When the display direction adjustment key is pressed, a control signal for direction adjustment indicating that the display direction needs to be adjusted. Is sent for a certain period of time.
　ディスプレイ装置２００は、受光センサ部２１０と、台座２２０と、表示パネル２３０と、を有する。 The display device 200 includes a light receiving sensor unit 210, a pedestal 220, and a display panel 230.
　受光センサ部２１０は、ディスプレイ装置２００の前面に設けられ、リモートコントローラ１００から送信されてきた制御信号を受信する。なお、受光センサ部２１０は、赤外線を透過するカバーで覆われている。 The light receiving sensor unit 210 is provided on the front surface of the display device 200 and receives a control signal transmitted from the remote controller 100. The light receiving sensor unit 210 is covered with a cover that transmits infrared rays.
　台座２２０は、表示パネル２３０を支持すると共に、表示パネル２３０の向きを水平方向に回転させるための不図示の表示パネル回転用モータを有しており、表示パネル２３０を水平方向に回転させる。 The pedestal 220 supports the display panel 230 and has a display panel rotation motor (not shown) for rotating the direction of the display panel 230 in the horizontal direction, and rotates the display panel 230 in the horizontal direction.
　リモートコントローラ１００は、表示方向調整用キーが押下されると、方向調整用の制御信号を一定時間送信する。ディスプレイ装置２００の受光センサ部２１０は、リモートコントローラ１００から送信されてきた方向調整用の制御信号を受信すると、その制御信号が送信されてきた方向を検出し、その検出した方向に表示パネル２３０を回転させる。ここで、制御信号が送信されてきた方向に視聴者がいると考えられるので、その検出した方向に表示パネル２３０を向けることで、視聴者に正対する向きに調整することができる。 When the display direction adjustment key is pressed, the remote controller 100 transmits a direction adjustment control signal for a certain period of time. When the light receiving sensor unit 210 of the display device 200 receives the direction adjustment control signal transmitted from the remote controller 100, the light reception sensor unit 210 detects the direction in which the control signal is transmitted, and moves the display panel 230 in the detected direction. Rotate. Here, since it is considered that the viewer is in the direction in which the control signal is transmitted, the display panel 230 is directed in the detected direction, so that the viewer can be adjusted to face the viewer.
　なお、制御信号が送信されてきた方向の検出方法の詳細については後述する。 Note that details of the method of detecting the direction in which the control signal has been transmitted will be described later.
　図２は、受光センサ部２１０の構成を示す三面図および斜視図である。図２において、（ａ）は受光センサ部２１０の上面図、（ｂ）は受光センサ部２１０の正面図、（ｃ）は受光センサ部２１０の側面図、（ｄ）は受光センサ部２１０の斜視図である。 FIG. 2 is a three-side view and a perspective view showing the configuration of the light receiving sensor unit 210. 2, (a) is a top view of the light receiving sensor unit 210, (b) is a front view of the light receiving sensor unit 210, (c) is a side view of the light receiving sensor unit 210, and (d) is a perspective view of the light receiving sensor unit 210. FIG.
　図２に示すように、受光センサ部２１０は、受光センサ２１１と、受光センサ２１２と、フード２１３と、回転台２１４と、ケース２１５と、受光センサ回転用モータ２１６と、を有する。 As shown in FIG. 2, the light receiving sensor unit 210 includes a light receiving sensor 211, a light receiving sensor 212, a hood 213, a turntable 214, a case 215, and a light receiving sensor rotating motor 216.
　なお、受光センサ２１１は、方向調整用受光センサの一例であり、受光センサ２１２は、センシング用受光センサの一例である。 The light receiving sensor 211 is an example of a direction adjusting light receiving sensor, and the light receiving sensor 212 is an example of a sensing light receiving sensor.
　受光センサ２１１および受光センサ２１２は、リモートコントローラ１００から送信されてきた制御信号を受信する。 The light receiving sensor 211 and the light receiving sensor 212 receive the control signal transmitted from the remote controller 100.
　ここで、受光センサ２１１は、赤外線を透過させず、かつ、内側は赤外線の乱反射を抑えるフード２１３で囲われている。このようなフード２１３は、上記の特性を奏するための処理を施したもの、または、上記の特性を奏する素材で作成することにより実現される。フード２１３で囲まれることにより、受光センサ２１１の制御信号の受信範囲は、所定の角度領域に制限される。なお、所定の角度領域は、要求される制御信号の送信方向の検出精度により定められ、要求される検出精度が高いほど、角度領域は狭くなる。 Here, the light receiving sensor 211 is surrounded by a hood 213 that does not transmit infrared light and suppresses irregular reflection of infrared light. Such a hood 213 is realized by creating a hood 213 that has been subjected to processing for achieving the above characteristics or a material that exhibits the above characteristics. By being surrounded by the hood 213, the reception range of the control signal of the light receiving sensor 211 is limited to a predetermined angle region. The predetermined angle region is determined by the required detection accuracy in the transmission direction of the control signal. The higher the required detection accuracy, the narrower the angle region.
　受光センサ２１１およびフード２１３は、回転台２１４上に配置されている。 The light receiving sensor 211 and the hood 213 are disposed on the turntable 214.
　また、受光センサ２１２は、ケース２１５の底部に固定されている。 The light receiving sensor 212 is fixed to the bottom of the case 215.
　フード２１３および回転台２１４には、垂直方向を回転の中心とした回転台軸があり、ケース２１５の回転台軸受部で保持されており、水平方向に回転することができる。更に、回転台２１４の一部には、受光センサ回転用モータ２１６のギアと噛み合うためのギアがあり、受光センサ回転用モータ２１６を駆動させることにより回転台２１４が水平方向に回転する。 The hood 213 and the turntable 214 have a turntable shaft with the vertical direction as the center of rotation. The hood 213 and the turntable 214 are held by a turntable bearing portion of the case 215 and can rotate in the horizontal direction. Further, a part of the turntable 214 has a gear for meshing with the gear of the light receiving sensor rotating motor 216, and the light receiving sensor rotating motor 216 is driven to rotate the turntable 214 in the horizontal direction.
　次に、受光センサ２１１および受光センサ２１２による制御信号の受信範囲について説明する。 Next, the reception range of control signals by the light receiving sensor 211 and the light receiving sensor 212 will be described.
　なお、以下では、ディスプレイ装置２００の正面方向を０度とし、正面方向から反時計回りの方向を正方向とする。 In the following, the front direction of the display device 200 is 0 degree, and the counterclockwise direction from the front direction is the positive direction.
　図３（ａ）および（ｂ）はそれぞれ、受光センサ２１１が、ディスプレイ装置２００の正面方向を向いている場合、および、ディスプレイ装置２００の正面方向から＋２５度の方向を向いている場合の受光センサ２１１および受光センサ２１２による制御信号の受信範囲を示す。 FIGS. 3A and 3B respectively show the light receiving sensor 211 when the light receiving sensor 211 faces the front direction of the display apparatus 200 and when the light receiving sensor 211 faces the direction of +25 degrees from the front direction of the display apparatus 200. The reception range of the control signal by 211 and the light receiving sensor 212 is shown.
　受光センサ２１１の受信範囲は、フード２１３に囲まれているために、受光センサ２１１の正面方向に鋭い指向性を有する。また、ディスプレイ装置２００から見た受光センサ２１１の受信範囲は、受光センサ２１１の向きにより変化する。そのため、リモートコントローラ１００から制御信号が送信されてくる方向が、受光センサ２１１の受信範囲内である場合には受信レベルが高くなり、それ以外の場合には受信レベルが低くなる。従って、受光センサ２１１による制御信号の受信レベルが高くなった際の受光センサ２１１の回転角度から、制御信号が送信されてくる方向を検出することができる。 Since the reception range of the light receiving sensor 211 is surrounded by the hood 213, the light receiving sensor 211 has a sharp directivity in the front direction of the light receiving sensor 211. Further, the reception range of the light receiving sensor 211 viewed from the display device 200 varies depending on the direction of the light receiving sensor 211. Therefore, when the direction in which the control signal is transmitted from the remote controller 100 is within the reception range of the light receiving sensor 211, the reception level is high, and in other cases, the reception level is low. Therefore, the direction in which the control signal is transmitted can be detected from the rotation angle of the light receiving sensor 211 when the reception level of the control signal by the light receiving sensor 211 becomes high.
　一方、受光センサ２１２は、受光センサ部２１０のケース２１５に固定されているため、受信範囲は一定であり、受光センサ２１１の受信範囲よりも広い。そのため、受光センサ２１２は、広範囲からの制御信号の受信に適している。 On the other hand, since the light receiving sensor 212 is fixed to the case 215 of the light receiving sensor unit 210, the receiving range is constant and wider than the receiving range of the light receiving sensor 211. Therefore, the light receiving sensor 212 is suitable for receiving control signals from a wide range.
　次に、ディスプレイ装置２００の構成について説明する。 Next, the configuration of the display device 200 will be described.
　図４は、ディスプレイ装置２００の構成を示すブロック図である。 FIG. 4 is a block diagram showing the configuration of the display device 200.
　図４に示すように、ディスプレイ装置２００は、受光センサ２１１と、受光センサ２１２と、受光センサ回転用モータ２１６と、表示パネル回転用モータ２２１と、制御部２４０と、を有する。 As shown in FIG. 4, the display device 200 includes a light receiving sensor 211, a light receiving sensor 212, a light receiving sensor rotating motor 216, a display panel rotating motor 221, and a control unit 240.
　また、制御部２４０は、メモリ２４１と、受信レベル最大値比較部２４２と、受光センサ回転用モータ制御部２４３と、表示パネル回転用モータ制御部２４４と、ＣＰＵ２４５と、を有する。 The control unit 240 includes a memory 241, a reception level maximum value comparison unit 242, a light receiving sensor rotation motor control unit 243, a display panel rotation motor control unit 244, and a CPU 245.
　なお、図４においては、受光センサ部２１０内のフード２１３、回転台２１４、およびケース２１５と、台座２２０と、表示パネル２３０と、については記載を省略している。 In FIG. 4, description of the hood 213, the turntable 214, the case 215, the pedestal 220, and the display panel 230 in the light receiving sensor unit 210 is omitted.
　以下では、視聴者によりリモートコントローラ１００に設けられた表示方向調整用キーが押下されたものとして説明する。 In the following description, it is assumed that the display direction adjustment key provided on the remote controller 100 is pressed by the viewer.
　リモートコントローラ１００は、視聴者により表示方向調整用キーが押下されると、方向調整用の制御信号を所定の時間送信する。なお、この所定の時間は、受光センサ２１１が所定の角度だけ回転するのに要する時間以上の時間が設定される。 When the viewer presses the display direction adjustment key, the remote controller 100 transmits a direction adjustment control signal for a predetermined time. The predetermined time is set to a time longer than the time required for the light receiving sensor 211 to rotate by a predetermined angle.
　受光センサ２１１は、受光センサ回転用モータ２１６により水平方向に回転された状態で所定の時間送信されてくる方向調整用の制御信号を受信し、各回転角度での制御信号の受信レベルを制御部２４０に出力する。 The light receiving sensor 211 receives the direction adjustment control signal transmitted for a predetermined time while being rotated in the horizontal direction by the light receiving sensor rotating motor 216, and controls the reception level of the control signal at each rotation angle. Output to 240.
　受光センサ２１２は、上述のように固定された状態で制御信号を受信し、受信した制御信号を示す情報を制御部２４０に出力する。 The light receiving sensor 212 receives the control signal in a fixed state as described above, and outputs information indicating the received control signal to the control unit 240.
　受光センサ回転用モータ２１６は、受光センサ回転用モータ制御部２４３からの指示に基づき、受光センサ２１１を水平方向に所定の角度の範囲で回転させる。なお、この所定の角度は、リモートコントローラ１００から制御信号が送信されてくる方向の検出を行う範囲により定まる。 The light receiving sensor rotating motor 216 rotates the light receiving sensor 211 in the horizontal direction within a predetermined angle range based on an instruction from the light receiving sensor rotating motor control unit 243. The predetermined angle is determined by the range in which the direction in which the control signal is transmitted from the remote controller 100 is detected.
　表示パネル回転用モータ２２１は、表示パネル回転用モータ制御部２４４からの指示に基づき、表示パネル２３０を水平方向に回転させる。即ち、表示パネル回転用モータ２２１は、受光センサ２１１と同じ回転軸にて表示パネル２３０を回転させる。 The display panel rotation motor 221 rotates the display panel 230 in the horizontal direction based on an instruction from the display panel rotation motor control unit 244. That is, the display panel rotation motor 221 rotates the display panel 230 on the same rotation axis as the light receiving sensor 211.
　メモリ２４１には、受光センサ２１１による制御信号の受信レベルの最大値、およびその受信レベルで受信された際の受光センサ２１１の回転角度が記憶情報として記憶される。なお、受光センサ２１１による制御信号の受信開始時には、その開始時での受信レベルおよび開始時の受光センサ２１１の回転角度が記憶情報として記憶される。 In the memory 241, the maximum value of the reception level of the control signal by the light receiving sensor 211 and the rotation angle of the light receiving sensor 211 when received at the reception level are stored as stored information. At the start of reception of the control signal by the light receiving sensor 211, the reception level at the start and the rotation angle of the light receiving sensor 211 at the start are stored as stored information.
　受信レベル最大値比較部２４２は、メモリ２４１に記憶された制御信号の受信レベルと受光センサ２１１の各回転角度での制御信号の受信レベルとを比較し、受光センサ２１１による制御信号の今回の受信レベルが、メモリ２４１に記憶された受信レベルよりも大きい場合には、メモリ２４１に記憶されている記憶情報を、今回の受信レベルおよびその受信レベルで受信された際の受光センサ２１１の回転角度に更新する。 The reception level maximum value comparison unit 242 compares the reception level of the control signal stored in the memory 241 with the reception level of the control signal at each rotation angle of the light receiving sensor 211, and receives the control signal this time by the light receiving sensor 211. When the level is higher than the reception level stored in the memory 241, the stored information stored in the memory 241 is set to the current reception level and the rotation angle of the light receiving sensor 211 when received at the reception level. Update.
　受光センサ回転用モータ制御部２４３は、受光センサ２１２により方向調整用の制御信号が受信されると、その制御信号が送信されてくる所定の時間内に受光センサ２１１を水平方向に所定の角度の範囲で回転させるように受光センサ回転用モータ２１６に指示する。 When the light receiving sensor 212 receives a direction adjustment control signal from the light receiving sensor 212, the light receiving sensor rotating motor control unit 243 moves the light receiving sensor 211 in a horizontal direction at a predetermined angle within a predetermined time when the control signal is transmitted. The light receiving sensor rotating motor 216 is instructed to rotate within the range.
　表示パネル回転用モータ制御部２４４は、受光センサ２１１の回転が終了すると、メモリ２４１に記憶された記憶情報から受光センサ２１１による制御信号の受信レベルが最大となる受光センサ２１１の向きを検出し、その検出した方向に応じて、表示パネル２３０を回転させるように表示パネル回転用モータ２２１に指示する。 When the rotation of the light receiving sensor 211 is completed, the display panel rotating motor control unit 244 detects the direction of the light receiving sensor 211 that maximizes the reception level of the control signal from the light receiving sensor 211 from the stored information stored in the memory 241. The display panel rotating motor 221 is instructed to rotate the display panel 230 according to the detected direction.
　ＣＰＵ２４５は、制御部２４０内の上述した各部を制御する。 The CPU 245 controls each unit described above in the control unit 240.
　次に、ディスプレイ装置２００の動作について説明する。 Next, the operation of the display device 200 will be described.
　図５は、表示パネル２３０の向きの調整時の動作を示すフローチャートである。 FIG. 5 is a flowchart showing the operation at the time of adjusting the orientation of the display panel 230.
　なお、以下では、図６に示すように、受光センサ２１１は、検出開始角度（－５０度）から検出終了角度（＋５０度）まで回転されるものとする。また、リモートコントローラ１００は、＋２５度の方向から制御信号を送信するものとする。 In the following, it is assumed that the light receiving sensor 211 is rotated from the detection start angle (−50 degrees) to the detection end angle (+50 degrees) as shown in FIG. Further, it is assumed that the remote controller 100 transmits a control signal from the direction of +25 degrees.
　まず、ＣＰＵ２４５は、メモリ２４１に記憶された記憶情報（前回、表示パネル２３０の向きの調整を行った際の、受光センサ２１１の受信レベルおよび回転角度）を初期化（クリア）する（ステップＳ１）。 First, the CPU 245 initializes (clears) storage information stored in the memory 241 (reception level and rotation angle of the light receiving sensor 211 when the orientation of the display panel 230 was previously adjusted) (step S1). .
　受光センサ回転用モータ制御部２４３は、受光センサ２１１を検出開始角度（－５０度）まで回転させるように受光センサ回転用モータ２１６に指示し、受光センサ回転用モータ２１６は、その指示に従い、受光センサ２１１を検出開始角度まで回転させる（ステップＳ２）。 The light reception sensor rotation motor control unit 243 instructs the light reception sensor rotation motor 216 to rotate the light reception sensor 211 to the detection start angle (−50 degrees), and the light reception sensor rotation motor 216 receives the light according to the instruction. The sensor 211 is rotated to the detection start angle (step S2).
　リモートコントローラ１００から方向調整用の制御信号が送信されると、受光センサ２１２は、その制御信号を受信し（ステップＳ３）、受信した方向調整用の制御信号を制御部２４０に出力する。 When the control signal for direction adjustment is transmitted from the remote controller 100, the light receiving sensor 212 receives the control signal (step S3), and outputs the received control signal for direction adjustment to the control unit 240.
　受信レベル最大値比較部２４２は、受光センサ２１１による制御信号の受信確認を行う（ステップＳ４）。 The reception level maximum value comparison unit 242 performs reception confirmation of the control signal by the light receiving sensor 211 (step S4).
　受光センサ２１２により方向調整用の制御信号が受信され、受光センサ２１１による制御信号の受信が確認されなかった場合（ステップＳ４：Ｎｏ）、受光センサ回転用モータ制御部２４３は、受光センサ２１１の回転角度が検出終了角度（＋５０度）に達したか否かを判定する（ステップＳ７）。この時点では、受光センサ２１１の回転角度は－５０度であり、＋５０度に達していないので、受光センサ回転用モータ制御部２４３は、受光センサ２１１を正方向に所定の角度分だけ回転させるように、受光センサ回転用モータ２１６に指示し、受光センサ回転用モータ２１６は、その指示に従い、受光センサ２１１を所定の角度分だけ回転させる（ステップＳ８）。 When the control signal for direction adjustment is received by the light receiving sensor 212 and the reception of the control signal by the light receiving sensor 211 is not confirmed (step S4: No), the light receiving sensor rotating motor control unit 243 rotates the light receiving sensor 211. It is determined whether or not the angle has reached the detection end angle (+50 degrees) (step S7). At this time, since the rotation angle of the light receiving sensor 211 is −50 degrees and has not reached +50 degrees, the light receiving sensor rotating motor control unit 243 rotates the light receiving sensor 211 in the positive direction by a predetermined angle. Then, the light receiving sensor rotating motor 216 is instructed, and the light receiving sensor rotating motor 216 rotates the light receiving sensor 211 by a predetermined angle in accordance with the instruction (step S8).
　その後、再び、受信レベル最大値比較部２４２は、受光センサ２１１による制御信号の受信確認を行う（ステップＳ４）。 Thereafter, the reception level maximum value comparison unit 242 confirms reception of the control signal by the light receiving sensor 211 again (step S4).
　受光センサ２１１による制御信号の受信が確認された場合（ステップＳ４：Ｙｅｓ）、受信レベル最大値比較部２４２は、その制御信号の受信レベルがメモリ２４１に記憶された受信レベルよりも大きいか否かを判定する（ステップＳ５）。 When reception of the control signal by the light receiving sensor 211 is confirmed (step S4: Yes), the reception level maximum value comparison unit 242 determines whether or not the reception level of the control signal is larger than the reception level stored in the memory 241. Is determined (step S5).
　なお、受信レベル最大値比較部２４２は、初めて受光センサ２１１による制御信号の受信が確認された際には、その時点での受光センサ２１１の回転角度の情報を受光センサ回転用モータ制御部２４３から取得し、その制御信号の受信レベルおよび回転角度を記憶情報としてメモリ２４１に記憶させる。その後、上述したステップＳ７およびＳ８の処理が行われる。 The reception level maximum value comparison unit 242 receives information about the rotation angle of the light receiving sensor 211 at that time from the light receiving sensor rotation motor control unit 243 when the reception of the control signal by the light receiving sensor 211 is confirmed for the first time. The reception level of the control signal and the rotation angle are acquired and stored in the memory 241 as storage information. Thereafter, the above-described steps S7 and S8 are performed.
　今回の制御信号の受信レベルがメモリ２４１に記憶された受信レベル以下の場合（ステップＳ５：Ｎｏ）、上述したステップＳ７およびＳ８の処理が行われる。 If the reception level of the current control signal is equal to or lower than the reception level stored in the memory 241 (step S5: No), the processes of steps S7 and S8 described above are performed.
　一方、今回の制御信号の受信レベルがメモリ２４１に記憶された受信レベルより大きい場合（ステップＳ５：Ｙｅｓ）、受信レベル最大値比較部２４２は、メモリ２４１に記憶されている記憶情報を、今回の制御信号の受信レベルおよびその受信レベルで受信された際の受光センサ２１１の回転角度に更新する（ステップＳ６）。その後、上述したステップＳ７およびＳ８の処理が行われる。 On the other hand, when the reception level of the current control signal is larger than the reception level stored in the memory 241 (step S5: Yes), the reception level maximum value comparison unit 242 uses the storage information stored in the memory 241 as the current storage level. The reception level of the control signal and the rotation angle of the light receiving sensor 211 when received at the reception level are updated (step S6). Thereafter, the above-described steps S7 and S8 are performed.
　受光センサ２１１の回転角度が検出終了角度に達した場合（ステップＳ７：Ｙｅｓ）、表示パネル回転用モータ制御部２４４は、メモリ２４１に記憶された記憶情報から制御信号の受信レベルが最大となる受光センサ２１１の向きを検出し、その検出した向きに表示パネル２３０を回転させるように表示パネル回転用モータ２２１に指示する。表示パネル回転用モータ２２１は、表示パネル回転用モータ制御部２４４からの指示に従い、表示パネル２３０を回転させる（ステップＳ９）。 When the rotation angle of the light receiving sensor 211 reaches the detection end angle (step S7: Yes), the display panel rotation motor control unit 244 receives the light whose control signal reception level is maximum from the stored information stored in the memory 241. The direction of the sensor 211 is detected, and the display panel rotation motor 221 is instructed to rotate the display panel 230 in the detected direction. The display panel rotation motor 221 rotates the display panel 230 in accordance with an instruction from the display panel rotation motor control unit 244 (step S9).
　図７は、受光センサ２１１の各回転角度での制御信号の受信レベルを示す図である。 FIG. 7 is a diagram showing the reception level of the control signal at each rotation angle of the light receiving sensor 211.
　上述したように、リモートコントローラ１００からは、＋２５度の方向から制御信号が送信されている。 As described above, the control signal is transmitted from the remote controller 100 from the direction of +25 degrees.
　受光センサ２１１の受信範囲は、受光センサ２１１の正面方向に鋭い指向性を有するため、リモートコントローラ１００から制御信号が送信されてくる＋２５度の回転角度の前後で、制御信号の受信が確認され、受光センサ２１１の回転角度が、リモートコントローラ１００と正対する、＋２５度の場合に、受信レベルが最大となる。メモリ２４１には、記憶情報として、制御信号の受信レベルが最大となった際の回転角度（＋２５度）が記憶され、その回転角度の方向に表示パネル２３０を回転させることで、視聴者に正対する向きに表示パネル２３０の向きを調整することができる。 Since the reception range of the light receiving sensor 211 has a sharp directivity in the front direction of the light receiving sensor 211, reception of the control signal is confirmed before and after a rotation angle of +25 degrees from which the control signal is transmitted from the remote controller 100, When the rotation angle of the light receiving sensor 211 is +25 degrees facing the remote controller 100, the reception level becomes maximum. The memory 241 stores, as stored information, a rotation angle (+25 degrees) when the reception level of the control signal is maximized, and the display panel 230 is rotated in the direction of the rotation angle so that the viewer can correct it. The direction of the display panel 230 can be adjusted to the direction to the opposite.
　このように本実施形態によれば、リモートコントローラ１００は、表示方向調整用キーが押下されると、方向調整用の制御信号を所定の時間送信する。また、ディスプレイ装置２００は、制御信号の受信範囲が所定の角度領域に制限された受光センサ２１１を回転させた状態で、リモートコントローラ１００から所定の時間送信されてくる制御信号を受信し、制御信号の受信レベルが最大となる受光センサ２１１の向きを検出し、その検出した向きに応じて、表示パネル２３０を回転させる。 As described above, according to the present embodiment, when the display direction adjustment key is pressed, the remote controller 100 transmits a direction adjustment control signal for a predetermined time. The display device 200 receives a control signal transmitted from the remote controller 100 for a predetermined time in a state where the light receiving sensor 211 whose reception range of the control signal is limited to a predetermined angle region is rotated, and receives the control signal. The direction of the light receiving sensor 211 having the maximum reception level is detected, and the display panel 230 is rotated according to the detected direction.
　そのため、一度、表示パネル２３０の姿勢を調整するためのキー操作を行えば制御信号が所定の時間送信され、その制御信号を受信する受光センサ２１１の向きに応じて、表示パネル２３０の向きが調整されるので、表示パネル２３０が希望の表示方向となるようにキー操作を続ける必要がなくなり、調整の手間を減らすことができ、また、受光センサ２１１の制御信号の受信範囲を適切に設定することで、受光センサの数を増やすことなく、精度良く表示パネル２３０の姿勢を調整することができる。 Therefore, once a key operation for adjusting the orientation of the display panel 230 is performed, a control signal is transmitted for a predetermined time, and the orientation of the display panel 230 is adjusted according to the orientation of the light receiving sensor 211 that receives the control signal. Therefore, it is not necessary to continue the key operation so that the display panel 230 is in the desired display direction, the adjustment time can be reduced, and the reception range of the control signal of the light receiving sensor 211 is set appropriately. Thus, the orientation of the display panel 230 can be adjusted with high accuracy without increasing the number of light receiving sensors.
　なお、本実施形態においては、ディスプレイ装置２００は、水平方向に表示パネル２３０の向きを調整する例について説明したが、本発明はこれに限られるものではない。例えば、受光センサ２１１および表示パネル２３０を垂直方向に回転させる機構を組み合わせて設けることにより、水平方向に加えて垂直方向に表示パネル２３０の向きを調整することができ、調整の自由度を向上することができる。 In the present embodiment, the display device 200 has been described with respect to an example in which the orientation of the display panel 230 is adjusted in the horizontal direction, but the present invention is not limited to this. For example, by providing a combination of mechanisms that rotate the light receiving sensor 211 and the display panel 230 in the vertical direction, the orientation of the display panel 230 can be adjusted in the vertical direction in addition to the horizontal direction, and the degree of freedom of adjustment is improved. be able to.
　また、本実施形態においては、リモートコントローラ１００とディスプレイ装置２００との間で制御信号として赤外線信号が送受信される例について説明したが、本発明はこれに限られるものではなく、赤外線信号以外の無線信号、例えば、超音波を用いて送受信を行うこととしてもよい。 In the present embodiment, an example in which an infrared signal is transmitted and received as a control signal between the remote controller 100 and the display device 200 has been described. However, the present invention is not limited to this, and wireless communication other than the infrared signal is performed. It is good also as performing transmission / reception using a signal, for example, an ultrasonic wave.
　以上、実施形態を参照して本願発明を説明したが、本発明は上記実施形態に限定されるものではない。本願発明の構成や詳細には、本願発明の範囲内で当業者が理解し得る様々な変更をすることができる。 As mentioned above, although this invention was demonstrated with reference to embodiment, this invention is not limited to the said embodiment. Various changes that can be understood by those skilled in the art can be made to the configuration and details of the present invention within the scope of the present invention.
