When a multi-display is constructed by arranging monitors with an operation input unit on the back of the monitor, etc., if the monitor is installed near the wall, the user can operate the operation input unit according to the arrangement of the monitor. Inability to monitor may occur. For example, when the operation input unit is arranged at the bottom of the back of the monitor, the user operates the monitor arranged at the bottom of the multi-display by extending his hand from the bottom of the monitor to the operation input unit. be able to. However, a monitor other than the monitor arranged at the bottom of the multi-display cannot be operated because the user's hand does not reach the operation input unit.
　特許文献１に記載の表示システムは、複数のモニターが通信ケーブルによって直列に接続され、最上流の表示装置が下流側の表示装置に設定されているデータを当該下流側の表示装置から受信した後、リモコンによる操作に応じてデータを更新し、当該データを下流側の表示装置へ送信する。すなわち、下流側の表示装置において設定されるデータの変更を、最上流の表示装置が行う。 In the display system described in Patent Document 1, a plurality of monitors are connected in series via a communication cable, and the most upstream display device receives data set in the downstream display device from the downstream display device. The data is updated according to the operation by the remote controller, and the data is transmitted to the downstream display device. That is, the most upstream display device changes the data set in the downstream display device.

　以下、本発明の実施の形態について図面を参照しながら説明する。
＜第１の実施形態＞
　図１は、本発明の第１の実施形態に係る表示システム１の概要を示す概略図である。図１に示すように、本発明の第１の実施形態に係る表示システム１は、複数の表示装置１０（１０ａ、１０ｂ、１０ｃ、および１０ｄ）と、複数の映像信号発生装置２０（２０ａ、および２０ｂ）と、通信線３０とから構成される。なお、以下の説明において、表示装置１０ａ、表示装置１０ｂ、表示装置１０ｃ、および表示装置１０ｄを特定しない場合は、単に表示装置１０といい、映像信号発生装置２０ａ、および映像信号発生装置２０ｂを特定しない場合は、単に映像信号発生装置２０という。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
<First Embodiment>
FIG. 1 is a schematic diagram showing an overview of a display system 1 according to the first embodiment of the present invention. As shown in FIG. 1, the display system 1 according to the first embodiment of the present invention includes a plurality of display devices 10 (10a, 10b, 10c, and 10d) and a plurality of video signal generators 20 (20a, and 20b) and a communication line 30. In the following description, when the display device 10a, the display device 10b, the display device 10c, and the display device 10d are not specified, they are simply referred to as the display device 10, and the video signal generator 20a and the video signal generator 20b are specified. If not, it is simply referred to as a video signal generator 20.
　図示するように、表示装置１０ａの上方には表示装置１０ｂが並べて配置され、表示装置１０ａの隣には表示装置１０ｃが並べて配置され、表示装置１０ｂの隣には表示装置１０ｄが並べて配置されることによって４つの表示装置１０からなるマルチディスプレイが構築されている。当該マルチディスプレイは通信線３０を介して映像信号発生装置２０から送信された映像信号を受信し、当該映像信号に基づく映像を表示する。 As shown in the drawing, a display device 10b is arranged side by side above the display device 10a, a display device 10c is arranged next to the display device 10a, and a display device 10d is arranged next to the display device 10b. Thus, a multi-display composed of four display devices 10 is constructed. The multi-display receives a video signal transmitted from the video signal generator 20 via the communication line 30 and displays a video based on the video signal.
　図２は、本発明の第１の実施形態に係る表示システム１における表示装置１０の背面の状態を示す概略図である。図示するように、表示装置１０の背面には、通信入力部１０１と、通信出力部１０２と、操作入力部１０４とがそれぞれ備えられている。そして、表示装置１０ａの通信出力部１０２と表示装置１０ｃの通信入力部１０１、表示装置１０ｃの通信出力部１０２と表示装置１０ｂの通信入力部１０１、および表示装置１０ｂの通信出力部１０２と表示装置１０ｄの通信入力部１０１、はそれぞれ通信線４０によって通信接続されている。 FIG. 2 is a schematic diagram showing the state of the back surface of the display device 10 in the display system 1 according to the first embodiment of the present invention. As illustrated, a communication input unit 101, a communication output unit 102, and an operation input unit 104 are provided on the back surface of the display device 10. The communication output unit 102 of the display device 10a and the communication input unit 101 of the display device 10c, the communication output unit 102 of the display device 10c and the communication input unit 101 of the display device 10b, and the communication output unit 102 of the display device 10b and the display device The communication input unit 101 of 10d is connected for communication by a communication line 40.
　すなわち、４つの表示装置１０は、表示装置１０ａ、表示装置１０ｃ、表示装置１０ｂ、表示装置１０ｄの順で直列に通信接続されている。このように、表示装置１０が通信接続されていることにより、表示装置１０ａ（最上流の表示装置１０）から表示装置１０ｄ（最下流の表示装置１０）へ、順に情報を伝達することができる。 That is, the four display devices 10 are connected in series in the order of the display device 10a, the display device 10c, the display device 10b, and the display device 10d. In this way, by the communication connection of the display device 10, information can be transmitted in order from the display device 10a (the most upstream display device 10) to the display device 10d (the most downstream display device 10).
　なお、表示装置１０は壁面の近くに設置されており、表示装置１０の背面と壁面とが隣接した状態で設置されているものとする。そのため、ユーザは、マルチディスプレイにおいて最下段に配置された表示装置１０ａまたは表示装置１０ｃの設定変更等を行いたい場合には、表示装置１０ａまたは表示装置１０ｃには脚部が設けられていることにより表示装置１０ａまたは表示装置１０ｃの下方から背面に手を伸ばして操作入力部１０４を操作することによって設定変更（操作入力）を行うことができる。しかしながら、表示装置１０ｂまたは表示装置１０ｄの設定変更などを行いたい場合には、表示装置１０ａまたは表示装置１０ｃの下方から背面に手を伸ばしても表示装置１０ｂまたは表示装置１０ｄの操作入力部１０４までは手が届かないため、設定変更（操作入力）を行うことができない。 It is assumed that the display device 10 is installed near the wall surface and the back surface of the display device 10 and the wall surface are adjacent to each other. Therefore, when the user wants to change the setting of the display device 10a or the display device 10c arranged at the bottom of the multi-display, the display device 10a or the display device 10c is provided with legs. A setting change (operation input) can be performed by operating the operation input unit 104 by reaching from the lower side of the display device 10a or the display device 10c to the back. However, when it is desired to change the setting of the display device 10b or the display device 10d, the operation input unit 104 of the display device 10b or the display device 10d can be reached even if the hand is reached from the lower side of the display device 10a or the display device 10c. Can not change the settings (operation input) because it is out of reach.
　そのため、本発明に係る表示システム１は、設定変更等に関する設定情報（制御情報）を上述した通信接続によって上流側の表示装置１０から下流側の表示装置１０へ伝達することにより、全ての表示装置１０の設定変更等の処理を可能にする。 Therefore, the display system 1 according to the present invention transmits all the display devices by transmitting the setting information (control information) regarding the setting change and the like from the upstream display device 10 to the downstream display device 10 through the communication connection described above. Allows processing such as 10 setting changes.
　なお、本実施例のように表示装置１０を２行２列に配置したマルチディスプレイだけに限らず、例えば、表示装置１０を１０行１０列に配置したマルチディスプレイに対しても同様に、全ての表示装置１０の設定変更等が可能である。 In addition, not only the multi-display in which the display device 10 is arranged in 2 rows and 2 columns as in the present embodiment, for example, the same applies to all the multi-displays in which the display device 10 is arranged in 10 rows and 10 columns. The setting of the display device 10 can be changed.
　なお、図２においては記載していないが、マルチディスプレイ用に表示させる映像を示す映像信号を伝達するための映像信号入力部、映像信号出力部がそれぞれの表示装置１０に備えられ、映像信号を伝達する通信線を用いて複数の表示装置１０の間で直列に通信接続されている構成であってもよい。もちろん、それぞれの表示装置１０が映像信号発生装置２０と通信接続し、それぞれの表示装置１０が個別に映像信号を取得するような構成であっても構わない。また、伝達される情報は、映像信号（映像情報）と設定情報（制御情報）とを別々の通信線を用いて伝達するように構成しているが、同じ通信線を用いて伝達するような構成であってもよい。 Although not shown in FIG. 2, each display device 10 is provided with a video signal input unit and a video signal output unit for transmitting a video signal indicating a video to be displayed for a multi-display. A configuration may be employed in which communication connections are made in series between the plurality of display devices 10 using a communication line for transmission. Of course, each display device 10 may be in communication connection with the video signal generation device 20, and each display device 10 may individually acquire a video signal. In addition, the information to be transmitted is configured to transmit the video signal (video information) and the setting information (control information) using separate communication lines. However, such information is transmitted using the same communication line. It may be a configuration.
　図３は、本発明の第１の実施形態に係る表示システム１における表示装置１０の識別情報の設定を示す概略図である。
　表示装置１０は、壁面に隣接して設置される前に、ユーザにより事前に、それぞれ識別情報の設定がなされる。識別情報の設定は、例えば、表示装置１０に備えられた機能であるＯＳＤ（Ｏｎ－Ｓｃｒｅｅｎ　Ｄｉｓｐｌａｙ；ディスプレイ表示設定）機能などを用いて行われる。 FIG. 3 is a schematic diagram showing identification information setting of the display device 10 in the display system 1 according to the first embodiment of the present invention.
Before the display device 10 is installed adjacent to the wall surface, identification information is set in advance by the user. The identification information is set using, for example, an OSD (On-Screen Display) function which is a function provided in the display device 10.
　図３は、それぞれの表示装置１０に識別情報の設定がなされ、ＯＳＤによってそれぞれの識別情報が表示された状態を表す。図示するように、図３における表示装置１０ａ、表示装置１０ｂ、表示装置１０ｃ、および表示装置１０ｄには、それぞれ「ＩＤ：１」、「ＩＤ：３」、「ＩＤ：２」、および「ＩＤ：４」と表示されている、ずなわち、図３における表示装置１０ａ、表示装置１０ｂ、表示装置１０ｃ、および表示装置１０ｄには、それぞれ「１」、「３」、「２」、および「４」というＩＤ（Ｉｄｅｎｔｉｆｉｅｒ；識別子）が設定されていることを表す。 FIG. 3 shows a state in which identification information is set on each display device 10 and each identification information is displayed by the OSD. As illustrated, the display device 10a, the display device 10b, the display device 10c, and the display device 10d in FIG. 3 have “ID: 1”, “ID: 3”, “ID: 2”, and “ID: In other words, the display device 10a, the display device 10b, the display device 10c, and the display device 10d in FIG. 3 are displayed as “1”, “3”, “2”, and “4”, respectively. "(Identifier) is set.
　図４は、本発明の第１の実施形態に係る表示システム１における操作対象とする表示装置１０の設定を示す概略図である。
　図示するように、表示装置１０ａには、「対象モニター：３」、および「個別制御：ＯＮ」と表示されている。この「対象モニター：３」という表示は、表示装置１０ａの操作キーによって設定がなされる対象となるモニターが、「３」というＩＤが割り当てられたモニター（すなわち、表示装置１０ｂ）である状態であることを示す。また、「個別制御：ＯＮ」という表示は、表示装置１０ａの操作キーによって、自らの表示装置１０ａではなく他の表示装置１０の設定を行うことができる機能（個別制御機能）が有効（ＯＮ）になっている状態（第２のモード）であることを示す。 FIG. 4 is a schematic diagram illustrating settings of the display device 10 to be operated in the display system 1 according to the first embodiment of the present invention.
As shown in the figure, “target monitor: 3” and “individual control: ON” are displayed on the display device 10a. The display “target monitor: 3” is a state in which the monitor to be set by the operation key of the display device 10a is the monitor to which the ID “3” is assigned (that is, the display device 10b). It shows that. In addition, the display of “individual control: ON” is enabled (ON) by a function (individual control function) that can set other display device 10 instead of its own display device 10a by an operation key of the display device 10a. This indicates that the state is (second mode).
　なお、ＯＳＤ機能等を用いてユーザにより操作対象となるモニターが選択されると自動的に個別制御機能がＯＮの状態（第２のモード）に変更されるような構成であってもよいし、または、ユーザにより個別制御機能がＯＮの状態（第２のモード）に変更された際に操作対象のモニターをユーザに選択させるような構成であってもよい。 The configuration may be such that the individual control function is automatically changed to the ON state (second mode) when the monitor to be operated is selected by the user using the OSD function or the like, Alternatively, the configuration may be such that the user selects the monitor to be operated when the individual control function is changed to the ON state (second mode) by the user.
　このように、本発明の第１の実施形態に係る表示システム１によれば、ユーザは、上流側の表示装置１０に備えられた操作入力部１０４（操作キー）を用いて、下流側の表示装置１０の設定変更などの操作を行うことができる。 Thus, according to the display system 1 according to the first embodiment of the present invention, the user uses the operation input unit 104 (operation key) provided in the upstream display device 10 to display the downstream display. Operations such as changing the settings of the apparatus 10 can be performed.
　図５は、本発明の第１の実施形態に係る表示システム１における表示装置１０の機能構成を示すブロック図である。
　図示するように、表示装置１０は、通信入力部１０１と、通信出力部１０２と、通信インターフェース１０３と、操作入力部１０４と、表示部１０５と、映像信号入力部１０６ａと、映像信号入力部１０６ｂと、映像信号出力部１０７と、映像用スイッチ１０８と、映像制御部１０９と、出力映像制御部１１０と、制御部１１１と、ＩＤ制御部１１２と、記憶部１１３と、ケーブル検出部１１４と、を含んで構成される。 FIG. 5 is a block diagram showing a functional configuration of the display device 10 in the display system 1 according to the first embodiment of the present invention.
As illustrated, the display device 10 includes a communication input unit 101, a communication output unit 102, a communication interface 103, an operation input unit 104, a display unit 105, a video signal input unit 106a, and a video signal input unit 106b. A video signal output unit 107, a video switch 108, a video control unit 109, an output video control unit 110, a control unit 111, an ID control unit 112, a storage unit 113, a cable detection unit 114, It is comprised including.
　通信入力部１０１は、接続された他の表示装置１０の後述する通信出力部１０２から、表示装置１０の設定に関する設定情報（制御情報）と設定対象である表示装置１０を識別する識別情報である対象識別情報とを取得する入力端子である。
　通信出力部１０２は、接続された他の表示装置１０へ設定情報（制御情報）と対象識別情報とを出力する出力端子である。
　通信インターフェース１０３は、通信入力部１０１および通信出力部１０２によって他の表示装置１０との情報の送受信を行う。 The communication input unit 101 is identification information for identifying setting information (control information) related to the setting of the display device 10 and the display device 10 to be set from the communication output unit 102 described later of the other connected display device 10. This is an input terminal for acquiring object identification information.
The communication output unit 102 is an output terminal that outputs setting information (control information) and target identification information to another connected display device 10.
The communication interface 103 transmits / receives information to / from another display device 10 through the communication input unit 101 and the communication output unit 102.
　操作入力部１０４は、ユーザによる操作入力を受け付ける入力インターフェース（例えば、操作キー）である。操作入力部１０４は、例えば、ユーザによる操作に基づいて表示装置１０の設定に関する設定情報（制御情報）と設定対象である表示装置１０を識別する対象識別情報とが入力される。操作入力部１０４は、操作入力に基づく各種の情報を制御部１１１へ出力する。
　表示部１０５は、後述する映像信号入力部１０６ａまたは映像信号入力部１０６ｂから入力される映像信号に基づく映像を表示するディスプレイ、例えば、液晶ディスプレイ（ＬＣＤ；Ｌｉｑｕｉｄ　Ｃｒｙｓｔａｌ　Ｄｉｓｐｌａｙ）または有機ＥＬ（ｅｌｅｃｔｒｏｌｕｍｉｎｅｓｃｅｎｃｅ）ディスプレイである。 The operation input unit 104 is an input interface (for example, an operation key) that receives an operation input by a user. For example, setting information (control information) related to the setting of the display device 10 and target identification information for identifying the display device 10 to be set are input to the operation input unit 104 based on an operation by the user. The operation input unit 104 outputs various information based on the operation input to the control unit 111.
The display unit 105 displays a video based on a video signal input from the video signal input unit 106a or the video signal input unit 106b, which will be described later, for example, a liquid crystal display (LCD) or an organic EL (electroluminescence) display. It is.
　映像信号入力部１０６ａおよび映像信号入力部１０６ｂは、それぞれ映像信号発生装置２０ａおよび映像信号発生装置２０ｂから送信された映像信号を、通信線３０を介して取得する。または、映像信号入力部１０６ａおよび映像信号入力部１０６ｂは、他の表示装置１０の後述する映像信号出力部１０７から送信された映像信号を、映像信号を伝達する通信線を介して取得する。 The video signal input unit 106a and the video signal input unit 106b acquire the video signals transmitted from the video signal generation device 20a and the video signal generation device 20b, respectively, via the communication line 30. Alternatively, the video signal input unit 106a and the video signal input unit 106b acquire the video signal transmitted from the video signal output unit 107 (to be described later) of the other display device 10 via a communication line that transmits the video signal.
　なお、以下の説明において、映像信号入力部１０６ａ、および、映像信号入力部１０６ｂを特定しない場合は、単に映像信号入力部１０６という。 In the following description, when the video signal input unit 106a and the video signal input unit 106b are not specified, they are simply referred to as the video signal input unit 106.
　なお、例えば、最上流の表示装置１０の映像信号入力部１０６は、映像信号発生装置２０から送信された映像信号を取得し、下流側の表示装置１０は自らの表示装置１０の１つ上流側の表示装置１０の映像信号出力部１０７から出力された映像信号を取得する。 For example, the video signal input unit 106 of the most upstream display device 10 acquires the video signal transmitted from the video signal generation device 20, and the downstream display device 10 is one upstream of its own display device 10. The video signal output from the video signal output unit 107 of the display device 10 is acquired.
　映像信号出力部１０７は、映像信号入力部１０６によって取得された映像信号を、映像信号を伝達する通信線を介して、他の表示装置１０の映像信号入力部１０６へ出力する。 The video signal output unit 107 outputs the video signal acquired by the video signal input unit 106 to the video signal input unit 106 of another display device 10 through a communication line that transmits the video signal.
　映像用スイッチ１０８は、映像信号入力部１０６ａまたは１０６ｂから入力された映像信号の１つを、後述する映像制御部１０９へ出力するように切り替える。また、映像用スイッチ１０８は、映像信号入力部１０６ａまたは１０６ｂから入力された映像信号の１つを、映像信号出力部１０７へ出力するように切り替える。なお、映像制御部１０９に出力する映像信号と、映像信号出力部１０７出力する映像信号とは、同じ信号であってもよいし、異なる信号であってもよい。 The video switch 108 switches so that one of the video signals input from the video signal input unit 106a or 106b is output to the video control unit 109 described later. The video switch 108 switches so that one of the video signals input from the video signal input unit 106 a or 106 b is output to the video signal output unit 107. Note that the video signal output to the video control unit 109 and the video signal output to the video signal output unit 107 may be the same signal or different signals.
　映像制御部１０９は、映像用スイッチ１０８から入力された映像信号を表示部１０５によって表示可能なデータ形式の映像データに変換し、後述する出力映像制御部１１０へ出力する。 The video control unit 109 converts the video signal input from the video switch 108 into video data in a data format that can be displayed by the display unit 105, and outputs the video data to the output video control unit 110 described later.
　出力映像制御部１１０は、映像制御部１０９から入力された映像データに基づく映像を表示部１０５に表示させる。 The output video control unit 110 causes the display unit 105 to display a video based on the video data input from the video control unit 109.
　制御部１１１は、操作入力部１０４から入力された操作入力に基づく制御情報（制御情報）に基づいて、表示装置１０の各機能ブロックを制御する。制御部１１１は、例えば、ＣＰＵ（Ｃｅｎｔｒａｌ　Ｐｒｏｃｅｓｓｉｎｇ　Ｕｎｉｔ；中央演算処理装置）を含んで構成される。 The control unit 111 controls each functional block of the display device 10 based on control information (control information) based on the operation input input from the operation input unit 104. The controller 111 includes, for example, a CPU (Central Processing Unit).
　例えば、制御部１１１は、自らの表示装置１０を識別する識別情報を設定する情報（制御情報）を操作入力部１０４から取得し、後述するＩＤ制御部１１２、および後述する記憶部１１３へ出力する。 For example, the control unit 111 acquires information (control information) for setting identification information for identifying its own display device 10 from the operation input unit 104 and outputs the information to the ID control unit 112 described later and the storage unit 113 described later. .
　また例えば、制御部１１１は、通信インターフェース１０３によって通信入力部１０１を介して取得された対象識別情報または操作入力部１０４によって取得された対象識別情報が、記憶部１１３に記憶された自らの表示装置１０に対応する識別情報と一致する場合には、取得した設定情報（制御情報）に基づいて自らの表示装置１０の設定変更等の処理を実行する。 Further, for example, the control unit 111 has its display device in which the target identification information acquired by the communication interface 103 via the communication input unit 101 or the target identification information acquired by the operation input unit 104 is stored in the storage unit 113. If it matches the identification information corresponding to 10, processing such as setting change of its own display device 10 is executed based on the acquired setting information (control information).
　また例えば、制御部１１１は、通信インターフェース１０３によって通信入力部１０１を介して取得された対象識別情報または操作入力部１０４によって取得された対象識別情報が、記憶部１１３に記憶された自らの表示装置１０に対応する識別情報と異なる場合には、当該対象識別情報および当該設定情報（制御情報）を、通信インターフェース１０３により通信出力部１０２を介して他の表示装置１０へ出力させる。 Further, for example, the control unit 111 has its display device in which the target identification information acquired by the communication interface 103 via the communication input unit 101 or the target identification information acquired by the operation input unit 104 is stored in the storage unit 113. 10, the target identification information and the setting information (control information) are output to another display device 10 via the communication output unit 102 by the communication interface 103.
　ＩＤ制御部１１２は、表示装置１０に設定される識別情報（ＩＤ）を制御する。例えば、ＩＤ制御部１１２は、自らの表示装置１０に設定された識別情報と他の表示装置１０に設定された識別情報とが同一である（重複している）場合には、互いに異なる識別情報となるように再設定させるための各種の制御を行う場合もあるし、同一の識別情報（ＩＤ）のまま、表示装置１０が、最上流の表示装置１０から、一斉に制御される場合もある。 The ID control unit 112 controls identification information (ID) set in the display device 10. For example, when the identification information set in its own display device 10 and the identification information set in another display device 10 are the same (overlapping), the ID control unit 112 has different identification information. In some cases, various controls for resetting the display device 10 may be performed, and the display device 10 may be simultaneously controlled from the most upstream display device 10 with the same identification information (ID). .
　記憶部１１３は、自らの表示装置１０に用いられる各種のデータやプログラムを記憶する。記憶部１１３は、例えば、自らの表示装置１０に設定された識別情報（ＩＤ）などを記憶する。記憶部１１３は、例えば、ハードディスクドライブ（ＨＤＤ；Ｈａｒｄ　Ｄｉｓｋ　Ｄｒｉｖｅ）、フラッシュメモリ、イーイーピーロム（ＥＥＰＲＯＭ；Ｅｌｅｃｔｒｉｃａｌｌｙ　Ｅｒａｓａｂｌｅ　Ｐｒｏｇｒａｍｍａｂｌｅ　Ｒｅａｄ　Ｏｎｌｙ　Ｍｅｍｏｒｙ）、ＲＯＭ（Ｒｅａｄ　Ｏｎｌｙ　Ｍｅｍｏｒｙ；読み出し専用メモリ）、ＲＡＭ（Ｒａｎｄｏｍ　Ａｃｃｅｓｓ　ｒｅａｄ／ｗｒｉｔｅ　Ｍｅｍｏｒｙ；読み書き可能なメモリ）、またはそれらの任意の組み合わせを含んで構成される。 The storage unit 113 stores various data and programs used for its own display device 10. The storage unit 113 stores, for example, identification information (ID) set in its own display device 10. The storage unit 113 includes, for example, a hard disk drive (HDD; Hard Disk Drive), a flash memory, an EEPROM (Electrically Erasable Programmable Read Only Memory), and a ROM (Read Only Memory and Read Only Memory) (Read Only Memory). / Write Memory; readable / writable memory), or any combination thereof.
　ケーブル検出部１１４は、入力端子（通信入力部１０１）にケーブル（通信線４０）が接続されているか否かを検出する。制御部１１１は、入力端子にケーブルが接続されていないことを検出したならば、自らの表示装置１０よりも上流の表示装置１０は存在しない、すなわち、自らの表示装置１０が最上流の表示装置１０であることを認識することができる。 The cable detection unit 114 detects whether or not the cable (communication line 40) is connected to the input terminal (communication input unit 101). If the control unit 111 detects that the cable is not connected to the input terminal, the display device 10 upstream of the display device 10 does not exist, that is, the display device 10 is the most upstream display device. 10 can be recognized.
　以下、表示装置１０の動作について説明する。
　図６および図７は、本発明の第１の実施形態に係る表示システム１の表示装置１０の動作の一例を示すフローチャートである。 Hereinafter, the operation of the display device 10 will be described.
6 and 7 are flowcharts showing an example of the operation of the display device 10 of the display system 1 according to the first embodiment of the present invention.
　まず、図６に示すフローチャートについて説明する。なお、図６に示すフローチャートは、最上流の表示装置１０（モニター（１））の動作の一例である。最上流の表示装置１０であるか否かを認識する方法は、上述したように、入力端子にケーブルが接続されていないことに基づいて認識する方法、または、識別情報として「ＩＤ：１」が設定されていることに基づいて認識する方法など、どのような方法でも構わない。
　図６に示すフローチャートは、最上流の表示装置１０（モニター（１））において、ユーザにより操作対象のモニターを設定する操作入力がなされた際に開始する。 First, the flowchart shown in FIG. 6 will be described. The flowchart shown in FIG. 6 is an example of the operation of the most upstream display device 10 (monitor (1)). As described above, the method of recognizing whether or not the display device 10 is the most upstream is the method of recognizing based on the fact that no cable is connected to the input terminal, or “ID: 1” as identification information. Any method, such as a method of recognizing based on the setting, may be used.
The flowchart shown in FIG. 6 starts when an operation input for setting an operation target monitor is performed by the user in the most upstream display device 10 (monitor (1)).
（ステップｓｔ００１）操作入力部１０４は、ユーザによる操作キーの操作に基づく情報を取得し、取得した情報を制御部１１１に出力する。その後、ステップｓｔ００２へ進む。 (Step st001) The operation input unit 104 acquires information based on an operation key operation by the user, and outputs the acquired information to the control unit 111. Thereafter, the process proceeds to step st002.
（ステップｓｔ００２）制御部１１１は、個別制御機能が「ＯＮ」（有効な状態（第２のモード））であるか否かを検出する。すなわち、制御部１１１は、操作入力部１０４が取得した情報に個別制御機能を「ＯＮ」（第２のモード）にさせる情報が含まれている、または既に個別制御機能が「ＯＮ」の状態（第２のモード）であるか否かを検出する。個別制御機能が「ＯＮ」（第２のモード）である場合には、ステップｓｔ００４へ進む。そうでない場合、すなわち、個別制御機能が「ＯＦＦ」（有効でない状態（第１のモード））である場合は、ステップｓｔ００３へ進む。 (Step st002) The control unit 111 detects whether or not the individual control function is “ON” (valid state (second mode)). That is, the control unit 111 includes information for turning the individual control function “ON” (second mode) in the information acquired by the operation input unit 104 or a state in which the individual control function is already “ON” ( It is detected whether or not the second mode). When the individual control function is “ON” (second mode), the process proceeds to step st004. If not, that is, if the individual control function is “OFF” (invalid state (first mode)), the process proceeds to step st003.
（ステップｓｔ００３）制御部１１１は、個別制御機能が「ＯＦＦ」（第１のモード）であることにより、操作入力部１０４が取得した情報に含まれる設定情報（制御情報）に基づいて、自らの表示装置１０の処理を実行する（すなわち、自己のモニター（１）を制御する）。以上で、本フローチャートの処理が終了する。 (Step st003) Since the individual control function is “OFF” (first mode), the control unit 111 determines its own control based on the setting information (control information) included in the information acquired by the operation input unit 104. The processing of the display device 10 is executed (that is, its own monitor (1) is controlled). Above, the process of this flowchart is complete | finished.
（ステップｓｔ００４）制御部１１１は、操作入力部１０４が取得した情報が特殊キーを示す情報であるか否かを検出する。操作入力部１０４が取得した情報が特殊キーを示す情報である場合には、ステップｓｔ００５へ進む。そうでない場合には、ステップｓｔ００６へ進む。 (Step st004) The control unit 111 detects whether the information acquired by the operation input unit 104 is information indicating a special key. If the information acquired by the operation input unit 104 is information indicating a special key, the process proceeds to step st005. Otherwise, the process proceeds to step st006.
　なお、特殊キーとは、ユーザが個別制御機能を「ＯＦＦ」（第１のモード）に切り替える場合に入力する操作キーのパターンである。例えば、特殊キーは、通常は使用しない複数のキーの組み合わせなどによって予め決められている。 The special key is a pattern of operation keys that are input when the user switches the individual control function to “OFF” (first mode). For example, the special key is determined in advance by a combination of a plurality of keys that are not normally used.
（ステップｓｔ００５）制御部１１１は、個別制御機能を「ＯＦＦ」の状態（第１のモード）に切り替える。以上で、本フローチャートの処理が終了する。 (Step st005) The control unit 111 switches the individual control function to the “OFF” state (first mode). Above, the process of this flowchart is complete | finished.
（ステップｓｔ００６）通信インターフェース１０３は、操作入力部１０４が取得した情報（設定情報（制御情報）および表示装置１０を識別する対象識別情報を含む情報）を、通信出力部１０２を介して他の表示装置１０（自らの表示装置１０の１つ下流側の表示装置１０）へ出力する。以上で、本フローチャートの処理が終了する。 (Step st006) The communication interface 103 displays the information acquired by the operation input unit 104 (information including setting information (control information) and target identification information for identifying the display device 10) via the communication output unit 102. The data is output to the device 10 (the display device 10 on the downstream side of the display device 10 of its own). Above, the process of this flowchart is complete | finished.
　次に、図７に示すフローチャートについて説明する。なお、図７に示すフローチャートは、最上流の表示装置１０（モニター（１））以外の表示装置、すなわち、下流側の表示装置１０の動作の一例である。
　図７に示すフローチャートは、表示装置１０の通信入力部１０１が、設定情報（制御情報）と対象識別情報とを含む情報を取得した際に開始する。 Next, the flowchart shown in FIG. 7 will be described. The flowchart shown in FIG. 7 is an example of the operation of a display device other than the most upstream display device 10 (monitor (1)), that is, the downstream display device 10.
The flowchart illustrated in FIG. 7 starts when the communication input unit 101 of the display device 10 acquires information including setting information (control information) and target identification information.
（ステップｓｔ０１１）通信入力部１０１は、他の表示装置１０から出力された、設定情報（制御情報）と対象識別情報とを含む情報を、通信線４０を介して取得し、取得した情報を制御部１１１に出力する。その後、ステップｓｔ０１２へ進む。 (Step st011) The communication input unit 101 acquires information including setting information (control information) and target identification information output from another display device 10 via the communication line 40, and controls the acquired information. Output to the unit 111. Thereafter, the process proceeds to step st012.
（ステップｓｔ０１２）制御部１１１は、通信入力部１０１が取得した情報に含まれる対象識別情報（ＩＤ）が、記憶部１１３に記憶された自らの表示装置１０を織別する識別情報（ＩＤ）と同一であるか否かを検出する。同一である場合には、ステップｓｔ０１３へ進む。そうでない場合は、ステップｓｔ０１４へ進む。 (Step st012) The control unit 111 includes identification information (ID) in which the target identification information (ID) included in the information acquired by the communication input unit 101 is classified by the display device 10 stored in the storage unit 113. Whether or not they are the same is detected. If they are the same, the process proceeds to step st013. Otherwise, the process proceeds to step st014.
（ステップｓｔ０１３）制御部１１１は、通信入力部１０１が取得した情報に含まれる設定情報（制御情報）に基づいて、自らの表示装置１０の処理を実行する（すなわち、自己のモニターを制御する）。その後、ステップｓｔ０１４へ進む。なお、取得した情報が自己のモニターのみを制御する情報であることが分かっている場合、制御部１１１は、ステップｓｔ０１４へ進まず、本フローチャートの処理を終了するようにしてもよい。 (Step st013) The control unit 111 executes the process of its own display device 10 based on the setting information (control information) included in the information acquired by the communication input unit 101 (that is, controls its own monitor). . Thereafter, the process proceeds to step st014. When it is known that the acquired information is information for controlling only its own monitor, the control unit 111 may not proceed to step st014 but may end the process of this flowchart.
（ステップｓｔ０１４）通信インターフェース１０３は、操作入力部１０４が取得した情報（設定情報（制御情報）および表示装置１０を識別する対象識別情報を含む情報）を、通信出力部１０２を介して他の表示装置１０（自らの表示装置１０の１つ下流側の表示装置１０）へ出力する。以上で、本フローチャートの処理が終了する。 (Step st014) The communication interface 103 displays the information acquired by the operation input unit 104 (information including setting information (control information) and target identification information for identifying the display device 10) via the communication output unit 102. The data is output to the device 10 (the display device 10 on the downstream side of the display device 10 of its own). Above, the process of this flowchart is complete | finished.
＜第２の実施形態＞
　次に、本発明の第２の実施形態について説明する。図８は、本発明の第２の実施形態に係る表示システム２の概要を示す概略図である。
　第２の実施形態に係る表示システム２では、ユーザは、リモートコントローラ（以下、リモコン６０という）によって、表示装置１０における設定変更等を実行することができる。 <Second Embodiment>
Next, a second embodiment of the present invention will be described. FIG. 8 is a schematic diagram showing an overview of the display system 2 according to the second embodiment of the present invention.
In the display system 2 according to the second embodiment, a user can execute a setting change or the like in the display device 10 using a remote controller (hereinafter referred to as a remote controller 60).
　なお、もしそれぞれの表示装置１０の前面にリモコン受光部が備えられているならば、リモコンを用いてそれぞれの表示装置１０における設定変更等を実行するように構成することが可能である。しかしながら、例えば、ベゼル幅の狭いモニターのように、リモコン受光部を表示装置１０の前面に設けることができない場合がある。その場合、リモコン受光部の設置位置によっては、マルチディスプレイにおいて、リモコンから送信された光を受光することができない表示装置１０が生じうる。 It should be noted that if a remote control light-receiving unit is provided on the front surface of each display device 10, it is possible to perform a setting change or the like in each display device 10 using the remote control. However, for example, the remote control light receiving unit may not be provided on the front surface of the display device 10 like a monitor with a narrow bezel width. In that case, depending on the installation position of the remote control light receiving unit, in the multi-display, the display device 10 that cannot receive the light transmitted from the remote control may occur.
　そこで、図８に示す表示システム２では、最上流の表示装置である表示装置１０ａにのみリモコン受光部５０を取り付けている。これにより、最上流の表示装置である表示装置１０ａの背面の操作入力部１０４を操作することによって下流側の表示装置１０における設定変更等を実行することができる第１の実施形態と同様に、第２の実施形態に係る表示システム２は、リモコン６０を操作することによって最上流の表示装置である表示装置１０ａに取り付けられたリモコン受光部５０を介して下流側の表示装置１０における設定変更等を実行することができる。すなわち、リモコン６０およびリモコン受光部５０は、操作入力部１０４の一例である。 Therefore, in the display system 2 shown in FIG. 8, the remote control light receiving unit 50 is attached only to the display device 10a which is the most upstream display device. Thus, similarly to the first embodiment in which setting change or the like in the downstream display device 10 can be executed by operating the operation input unit 104 on the back surface of the display device 10a which is the most upstream display device, In the display system 2 according to the second embodiment, by operating the remote controller 60, setting changes in the downstream display device 10 are performed via the remote control light receiving unit 50 attached to the display device 10a which is the most upstream display device. Can be executed. That is, the remote control 60 and the remote control light receiving unit 50 are examples of the operation input unit 104.
　なお、第２の実施形態に係る表示システム２のようにリモコン６０が用いられる場合には、下流側の全ての表示装置１０のリモコン受光部（図示せず）は無効となるように設定されることが望ましい。 When the remote control 60 is used as in the display system 2 according to the second embodiment, the remote control light receiving units (not shown) of all the downstream display devices 10 are set to be invalid. It is desirable.
＜第３の実施形態＞
　次に、本発明の第３の実施形態について説明する。図９は、本発明の第３の実施形態に係る表示システム３の概要を示す概略図である。 <Third Embodiment>
Next, a third embodiment of the present invention will be described. FIG. 9 is a schematic view showing an outline of the display system 3 according to the third embodiment of the present invention.
　図示するように、第３の実施形態に係る表示システム３においては、制御部１１１は、表示システム３を構成する複数の表示装置１０（図９においては、１０ａ、１０ｂ、１０ｃ、および１０ｄ）を示す画像を、ＯＳＤを用いて特定の表示装置１０の表示部１０５に表示させ、当該複数の表示装置１０の配置状態を表す画像をユーザに対して提示する。そして、制御部１１１は、ユーザからの操作入力に基づき、特定の表示装置１０の表示部１０５に表示された複数の表示装置１０のうち所定の１つの表示装置１０が選択されることにより、選択された表示装置１０に対応する識別情報を対象識別情報として設定する。 As shown in the figure, in the display system 3 according to the third embodiment, the control unit 111 includes a plurality of display devices 10 (10a, 10b, 10c, and 10d in FIG. 9) constituting the display system 3. An image to be displayed is displayed on the display unit 105 of the specific display device 10 using the OSD, and an image representing the arrangement state of the plurality of display devices 10 is presented to the user. Then, the control unit 111 selects a predetermined display device 10 among a plurality of display devices 10 displayed on the display unit 105 of the specific display device 10 based on an operation input from the user. The identification information corresponding to the displayed display device 10 is set as the target identification information.
　図９は、表示システム３を構成する複数の表示装置１０（１０ａ、１０ｂ、１０ｃ、および１０ｄ）のうち、向かって左上側に配置された表示装置１０であって「ＩＤ：３」の識別情報が対応付けられた表示装置１０である表示装置１０ｂが選択された状態を表した図である。 FIG. 9 shows the display device 10 arranged on the upper left side among the plurality of display devices 10 (10a, 10b, 10c, and 10d) constituting the display system 3, and identification information “ID: 3”. It is the figure showing the state as which the display apparatus 10b which is the display apparatus 10 matched with is selected.
　このように、第３の実施形態に係る表示システム３は、表示システム３を構成する複数の表示装置１０（図９においては、１０ａ、１０ｂ、１０ｃ、および１０ｄ）を示す画像を、ＯＳＤを用いて特定の表示装置１０の表示部１０５に視覚的に表示するため、ユーザは、設定変更等の制御の対象としたい表示装置１０をより容易に選択することができる。 As described above, the display system 3 according to the third embodiment uses an OSD to display an image showing a plurality of display devices 10 (10a, 10b, 10c, and 10d in FIG. 9) constituting the display system 3. Since it is visually displayed on the display unit 105 of the specific display device 10, the user can more easily select the display device 10 that is desired to be controlled such as setting change.
　第３の実施形態に係る表示システム３によれば、多数の表示装置１０によって構成されるマルチディスプレイである場合であっても、ユーザは、多数の表示装置１０の表示部１０５をそれぞれ確認することはせずに特定の表示装置１０の表示部１０５のみを確認するだけでよいため、設定変更等の制御の対象としたい表示装置１０をより容易に選択することができる。 According to the display system 3 according to the third embodiment, even in the case of a multi-display configured by a large number of display devices 10, the user confirms the display units 105 of the large number of display devices 10, respectively. Since it is only necessary to confirm only the display unit 105 of the specific display device 10 without performing the selection, it is possible to more easily select the display device 10 that is desired to be controlled such as setting change.
　図１０は、本発明の第１乃至第３の実施形態に係る表示システムの表示装置１０の基本構成を示すブロック図である。
　図示するように、表示装置１０は、通信可能に接続された複数の表示装置１０を有する表示システムを構成する表示装置であって、映像を表示する表示部１０５と、ユーザによる操作を受け付ける操作入力部１０４と、前記操作に対応する制御情報を実行する表示装置１０を指定する対象識別情報が自らの表示装置１０に対応付けられた識別情報と同じである場合、前記制御情報に基づいて処理を実行する制御部１１１と、前記対象識別情報が自らの表示装置１０に対応付けられた識別情報と異なる場合、接続された他の表示装置１０へ前記制御情報と前記対象識別情報とを出力する通信出力部１０２と、を備える。 FIG. 10 is a block diagram showing a basic configuration of the display device 10 of the display system according to the first to third embodiments of the present invention.
As shown in the figure, the display device 10 is a display device that constitutes a display system having a plurality of display devices 10 that are communicably connected to each other, and includes a display unit 105 that displays an image and an operation input that receives an operation by a user. When the target identification information that designates the display device 10 that executes the control information corresponding to the operation of the unit 104 and the operation is the same as the identification information associated with the display device 10 of its own, the processing is performed based on the control information. Communication for outputting the control information and the target identification information to another connected display device 10 when the control unit 111 to be executed and the target identification information are different from the identification information associated with its own display device 10 And an output unit 102.
　以上、説明したように、本発明の第１の実施形態に係る表示システム１、第２の実施形態に係る表示システム２、および第３の実施形態に係る表示システム３では、表示装置１０における設定変更等の処理を実行させるための設定情報（制御情報）を、最上流の表示装置１０から直列に通信接続された下流側の表示装置１０へ順に伝達していけばよいため、ユーザは、下流側の表示装置１０における設定変更等を、より容易に行うことができる。 As described above, in the display system 1 according to the first embodiment of the present invention, the display system 2 according to the second embodiment, and the display system 3 according to the third embodiment, the setting in the display device 10 is performed. Since the setting information (control information) for executing processing such as change may be transmitted in order from the most upstream display device 10 to the downstream display device 10 connected in series, the user can A setting change or the like in the display device 10 on the side can be performed more easily.
　本発明の第１の実施形態に係る表示システム１、第２の実施形態に係る表示システム２、および第３の実施形態に係る表示システム３では、個別制御機能が有効な状態にされた最上流の表示装置１０は、操作入力部１０４やリモコン６０による操作に基づく設定情報（制御情報）に操作対象とする表示装置１０を識別する識別情報を付加して、下流側の表示装置１０へ伝達する。操作対象である表示装置１０は、当該設定情報（制御情報）に基づく設定を実行する。 In the display system 1 according to the first embodiment of the present invention, the display system 2 according to the second embodiment, and the display system 3 according to the third embodiment, the most upstream in which the individual control function is enabled The display device 10 adds identification information for identifying the display device 10 to be operated to setting information (control information) based on the operation by the operation input unit 104 or the remote controller 60 and transmits the identification information to the downstream display device 10. . The display device 10 that is the operation target executes setting based on the setting information (control information).
　すなわち、個別制御機能が有効な状態にされた最上流の表示装置１０は、操作対象とする表示装置１０に対応する識別情報を付加して設定情報（制御情報）を送信するため、本発明によれば、設定情報（制御情報）の送信先とする表示装置１０がどの表示装置１０であるかを判定するための判定処理が不要になる。
　また、本発明によれば、最上流の表示装置１０は、操作対象とする表示装置１０の設定前の時点での設定情報（制御情報）を事前に取得する必要もないため、下流側の表示装置１０における設定変更等の処理を、より容易に実行することができる。 That is, the most upstream display device 10 in which the individual control function is enabled adds identification information corresponding to the display device 10 to be operated and transmits setting information (control information). According to this, a determination process for determining which display device 10 is the display device 10 to which the setting information (control information) is transmitted becomes unnecessary.
In addition, according to the present invention, the most upstream display device 10 does not need to obtain the setting information (control information) at the time before the setting of the display device 10 to be operated in advance. Processing such as setting change in the apparatus 10 can be executed more easily.
　なお、上述した実施形態においては、上流側の表示装置１０から下流側の表示装置１０へのみ情報が伝達される単方向通信であるものとしたが、これに限られない。下流側の表示装置１０から上流側の表示装置１０へのフィードバックが可能な双方向通信である場合には、例えば、ユーザは、最下流の表示装置１０の操作キーを操作することによって、当該表示装置１０が最下流ではなく最上流の表示装置１０となるように設定を変更することが可能になる。 In the above-described embodiment, the unidirectional communication in which information is transmitted only from the upstream display device 10 to the downstream display device 10 is not limited to this. In the case of bidirectional communication in which feedback from the downstream display device 10 to the upstream display device 10 is possible, for example, the user operates the operation key of the most downstream display device 10 to display the display. It is possible to change the setting so that the device 10 is not the most downstream but the most upstream display device 10.
　また、下流側の表示装置１０から上流側の表示装置１０へのフィードバックが可能な双方向通信である場合、上流側の表示装置１０は下流側の表示装置１０から、エラー情報などの情報を取得することによって、エラー処理をより確実に行うようにすることもできる。 Further, in the case of bidirectional communication in which feedback from the downstream display device 10 to the upstream display device 10 is possible, the upstream display device 10 acquires information such as error information from the downstream display device 10. By doing so, error processing can be performed more reliably.
　例えば、最上流の表示装置１０の個別制御機能がＯＮの状態（第２のモード）であるときに、ユーザが最下流の表示装置１０の操作キーを操作して最下流の表示装置１０の個別制御機能をＯＮの状態（第２のモード）に変更すると、最上流の表示装置１０の個別制御機能をＯＦＦにさせる（第１のモードにする）ための制御情報が、最下流の表示装置１０から最上流の表示装置１０へ順に伝達されるようにしてもよい。これにより、最下流であった表示装置１０が最上流の表示装置１０であるように変更することが可能になる。 For example, when the individual control function of the most upstream display device 10 is in the ON state (second mode), the user operates the operation key of the most downstream display device 10 to individually select the most downstream display device 10. When the control function is changed to the ON state (second mode), the control information for turning off the individual control function of the most upstream display device 10 (to enter the first mode) is the most downstream display device 10. To the most upstream display device 10 in order. Accordingly, it is possible to change the display device 10 that has been the most downstream to be the most upstream display device 10.
　また、最上流でもなく最下流でもない中間に位置する表示装置１０の操作キーが操作された場合であっても、双方向通信である場合には、全ての表示装置１０へ情報伝達が可能であるため、上記のような最上流の表示装置１０を変更するような処理も可能である。 Further, even when the operation key of the display device 10 located in the middle that is neither the most upstream nor the most downstream is operated, information can be transmitted to all the display devices 10 in the case of bidirectional communication. Therefore, it is possible to perform processing for changing the most upstream display device 10 as described above.
　なお、表示システム１、表示システム２、表示システム３、または表示装置１０の全部または一部の機能を実現するためのプログラムをコンピュータ読み取り可能な記録媒体に記録して、この記録媒体に記録されたプログラムをコンピュータシステムに読み込ませ、実行することにより各部の処理を行ってもよい。なお、ここでいう「コンピュータシステム」とは、ＯＳや周辺機器等のハードウェアを含むものとする。
　また、「コンピュータシステム」は、ＷＷＷシステムを利用している場合であれば、ホームページ提供環境（あるいは表示環境）も含むものとする。
　また、「コンピュータ読み取り可能な記録媒体」とは、フレキシブルディスク、光磁気ディスク、ＲＯＭ、ＣＤ－ＲＯＭ等の可搬媒体、コンピュータシステムに内蔵されるハードディスク等の記憶装置のことをいう。さらに「コンピュータ読み取り可能な記録媒体」とは、インターネット等のネットワークや電話回線等の通信回線を介してプログラムを送信する場合の通信線のように、短時間の間、動的にプログラムを保持するもの、その場合のサーバやクライアントとなるコンピュータシステム内部の揮発性メモリのように、一定時間プログラムを保持しているものも含むものとする。また上記プログラムは、前述した機能の一部を実現するためのものであっても良く、さらに前述した機能をコンピュータシステムにすでに記録されているプログラムとの組み合わせで実現できるものであっても良い。 A program for realizing all or part of the functions of display system 1, display system 2, display system 3, or display device 10 is recorded on a computer-readable recording medium and recorded on the recording medium. Processing of each unit may be performed by causing a computer system to read and execute the program. Here, the “computer system” includes an OS and hardware such as peripheral devices.
Further, the “computer system” includes a homepage providing environment (or display environment) if a WWW system is used.
The “computer-readable recording medium” refers to a storage device such as a flexible medium, a magneto-optical disk, a portable medium such as a ROM or a CD-ROM, and a hard disk incorporated in a computer system. Furthermore, the “computer-readable recording medium” dynamically holds a program for a short time like a communication line when transmitting a program via a network such as the Internet or a communication line such as a telephone line. In this case, a volatile memory in a computer system serving as a server or a client in that case, and a program that holds a program for a certain period of time are also included. The program may be a program for realizing a part of the functions described above, and may be a program capable of realizing the functions described above in combination with a program already recorded in a computer system.
