The signal detection unit 120 detects the input of the video signal from the source device to each of the plurality of signal input units 110. The display processing unit 130 displays an image based on the image signal received via the signal input unit 110 in the display area of the image display device 10. Here, it is assumed that the signal detection unit 120 detects the input of a video signal for two or more signal input units 110. In this case, the display processing unit 130 receives each video signal input to each of the two or more signal input units 110 based on the position of each of the two or more signal input units 110 to which the video signal is input. Determine the display mode of each image based on. Then, the display processing unit 130 displays each image in the display area according to the display mode determined for each image.
　＜ハードウエア構成例＞

The video display device 10 includes a bus 1010, a processor 1020, a memory 1030, a storage device 1040, an input / output interface 1050, and a network interface 1060.
　バス１０１０は、プロセッサ１０２０、メモリ１０３０、ストレージデバイス１０４０、入出力インタフェース１０５０、及びネットワークインタフェース１０６０が、相互にデータを送受信するためのデータ伝送路である。ただし、プロセッサ１０２０などを互いに接続する方法は、バス接続に限定されない。 The bus 1010 is a data transmission path for the processor 1020, the memory 1030, the storage device 1040, the input / output interface 1050, and the network interface 1060 to transmit and receive data to each other. However, the method of connecting the processors 1020 and the like to each other is not limited to the bus connection.
　プロセッサ１０２０は、ＣＰＵ（Central Processing Unit） やＧＰＵ（Graphics Processing Unit）などで実現されるプロセッサである。 The processor 1020 is a processor realized by a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), or the like.

　メモリ１０３０またはストレージデバイス１０４０は、映像表示装置１０の各機能（信号検出部１２０、表示処理部１３０など）を実現するプログラムモジュールを記憶している。プロセッサ１０２０がこれら各プログラムモジュールを実行することで、各プログラムモジュールに対応する各機能が実現される。 The memory 1030 or the storage device 1040 stores a program module that realizes each function of the video display device 10 (signal detection unit 120, display processing unit 130, etc.). When the processor 1020 executes each of these program modules, each function corresponding to each program module is realized.
　入出力インタフェース１０５０は、映像表示装置１０と各種入出力機器とを接続するためのインタフェースである。入出力インタフェース１０５０には、映像信号を提供するソース機器２０やソース機器２０からの映像信号に基づく映像を表示するディスプレイなどが接続される。入出力インタフェース１０５０のうち、映像表示装置１０と映像信号を提供するソース機器２０とを接続するインタフェースは、上述の信号入力部１１０に相当する。 The input / output interface 1050 is an interface for connecting the video display device 10 and various input / output devices.

　＜処理の流れ＞
　図３は、第1実施形態の映像表示装置１０により実行される処理の流れを例示するフローチャートである。 <Processing flow>
FIG. 3 is a flowchart illustrating the flow of processing executed by the video display device 10 of the first embodiment.
　信号検出部１２０は、複数の信号入力部１１０それぞれと電気的に接続されており、複数の信号入力部１１０それぞれに対する映像信号の入力状態を監視している（Ｓ１０２、Ｓ１０４）。一例として、信号検出部１２０は、信号入力部１１０に対する映像信号を検出可能に構成されており、ある信号入力部１１０について映像信号が検出された場合に、当該信号入力部１１０を「映像信号が入力されている信号入力部」として識別してもよい。他の一例として、信号検出部１２０は、各信号入力部１１０での接続状態を検出可能に構成されており、ある信号入力部１１０に対して映像ケーブルまたは無線通信ドングルが接続されたことを検出した場合に、当該信号入力部１１０を「映像信号が入力されている信号入力部」として識別してもよい。信号検出部１２０は、少なくとも１つの信号入力部１１０について映像信号の入力を検出すると（Ｓ１０４：ＹＥＳ）、映像信号が入力されている信号入力部１１０を示す情報を表示処理部１３０に通知する（Ｓ１０６）。 The signal detection unit 120 is electrically connected to each of the plurality of signal input units 110, and monitors the input state of the video signal to each of the plurality of signal input units 110 (S102, S104). As an example, the signal detection unit 120 is configured to be able to detect a video signal for the signal input unit 110, and when a video signal is detected for a certain signal input unit 110, the signal input unit 110 is "video signal is". It may be identified as "the input signal input unit". As another example, the signal detection unit 120 is configured to be able to detect the connection state of each signal input unit 110, and detects that a video cable or a wireless communication dongle is connected to a certain signal input unit 110. If so, the signal input unit 110 may be identified as a "signal input unit to which a video signal is input". When the signal detection unit 120 detects the input of a video signal for at least one signal input unit 110 (S104: YES), the signal detection unit 120 notifies the display processing unit 130 of information indicating the signal input unit 110 to which the video signal is input (S104: YES). S106).
　次に、表示処理部１３０は、信号検出部１２０による映像信号の検出結果に基づいて、複数の信号入力部１１０について映像信号の入力が検出されたか否かを判定する（Ｓ１０８）。単一の信号入力部１１０について映像信号の入力が検出された場合（Ｓ１０８：ＮＯ）、表示処理部１３０は、例えば、当該映像信号に基づく映像を映像表示部１３４に全画面表示させる（Ｓ１１４）。一方、複数の信号入力部１１０について映像信号の入力が検出された場合（Ｓ１０８：ＹＥＳ）、表示処理部１３０は、映像信号が入力されている複数の信号入力部１１０の位置関係に基づいて、各映像信号に基づく各映像の表示態様を決定する（Ｓ１１０）。表示処理部１３０は、例えば、映像の表示位置、映像の表示階層、映像の表示サイズ、映像の視野角および映像の表示角度の少なくとも１つを制御する。表示処理部１３０による映像の表示態様の制御の具体的な例については後述する。そして、表示処理部１３０は、Ｓ１０８の処理で各々の映像について決定された表示態様に従って、各々の映像を映像表示部１３４に表示させる（Ｓ１１０）。 Next, the display processing unit 130 determines whether or not the input of the video signal is detected for the plurality of signal input units 110 based on the detection result of the video signal by the signal detection unit 120 (S108). When the input of a video signal is detected for a single signal input unit 110 (S108: NO), the display processing unit 130 causes the video display unit 134 to display the video based on the video signal in full screen (S114). .. On the other hand, when the input of the video signal is detected for the plurality of signal input units 110 (S108: YES), the display processing unit 130 is based on the positional relationship of the plurality of signal input units 110 to which the video signal is input. The display mode of each video based on each video signal is determined (S110). The display processing unit 130 controls, for example, at least one of a video display position, a video display hierarchy, a video display size, a video viewing angle, and a video display angle. A specific example of controlling the display mode of the image by the display processing unit 130 will be described later. Then, the display processing unit 130 causes the video display unit 134 to display each video according to the display mode determined for each video in the processing of S108 (S110).
　以下、映像表示装置１０に設けられる複数の信号入力部１１０の配置と映像表示装置１０の動作について、いくつか具体例を挙げて説明する。 Hereinafter, the arrangement of the plurality of signal input units 110 provided in the video display device 10 and the operation of the video display device 10 will be described with some specific examples.
　＜第１の具体例＞
　図４は、複数の信号入力部１１０の第１の配置例を示す図である。また、図５は、図４に示される映像表示装置１０の構成を例示する図である。 <First specific example>
FIG. 4 is a diagram showing a first arrangement example of the plurality of signal input units 110. Further, FIG. 5 is a diagram illustrating the configuration of the video display device 10 shown in FIG.
　本具体例における映像表示装置１０は、２つの信号入力部１１０（第１の信号入力部１１０－１および第２の信号入力部１１０－２）を有している。第１の信号入力部１１０－１は、映像表示装置１０の左の側面に設けられている。第１の信号入力部１１０－１には、第１のソース機器２０－１が接続されている。第２の信号入力部１１０－２は、映像表示装置１０の右の側面に設けられている。第２の信号入力部１１０－２には、第２のソース機器２０－２が接続されている。 The video display device 10 in this specific example has two signal input units 110 (first signal input unit 110-1 and second signal input unit 110-2). The first signal input unit 110-1 is provided on the left side surface of the video display device 10. The first source device 20-1 is connected to the first signal input unit 110-1. The second signal input unit 110-2 is provided on the right side surface of the video display device 10. A second source device 20-2 is connected to the second signal input unit 110-2.
　また、映像表示装置１０は、第１の信号入力部１１０－１および第２の信号入力部１１０－２それぞれについて、第１の映像入力検出部１２２－１および第２の映像入力検出部１２２－２を備えている。第１の映像入力検出部１２２－１および第２の映像入力検出部１２２－２は、それぞれ、第１の信号入力部１１０－１を介して入力される映像信号および第２の信号入力部１１０－２を介して入力される映像信号を捕捉する。 Further, in the video display device 10, for each of the first signal input unit 110-1 and the second signal input unit 110-2, the first video input detection unit 122-1 and the second video input detection unit 122- It has 2. The first video input detection unit 122-1 and the second video input detection unit 122-2 are the video signal input via the first signal input unit 110-1 and the second signal input unit 110, respectively. Captures the video signal input via -2.
　プロセッサ１０２０は、メモリ１０３０またはストレージデバイス１０４０に記憶されている信号検出部１２０および表示処理部１３０のプログラムモジュールを実行し、信号検出部１２０の機能および表示処理部１３０の機能を実現する。信号検出部１２０は、第１の映像入力検出部１２２－１および第２の映像入力検出部１２２－２それぞれの映像信号の捕捉結果から、第１の信号入力部１１０－１および第２の信号入力部１１０－２に対する映像信号の入力を検出する。表示処理部１３０は、例えば次のように動作する。 The processor 1020 executes the program modules of the signal detection unit 120 and the display processing unit 130 stored in the memory 1030 or the storage device 1040, and realizes the functions of the signal detection unit 120 and the function of the display processing unit 130. The signal detection unit 120 has the first signal input unit 110-1 and the second signal based on the acquisition results of the video signals of the first video input detection unit 122-1 and the second video input detection unit 122-2, respectively. The input of the video signal to the input unit 110-2 is detected. The display processing unit 130 operates as follows, for example.
　信号検出部１２０が、第１の信号入力部１１０－１および第２の信号入力部１１０－２のいずれか一方のみについて映像信号の入力を検出したとする。この場合、表示処理部１３０は、第１の信号入力部１１０－１および第２の信号入力部１１０－２のうちのいずれか一方に入力された映像信号を映像処理回路１３２を用いて処理し、当該映像信号に基づく映像を映像表示装置１０の表示領域（映像表示部１３４）に全画面表示させる。 It is assumed that the signal detection unit 120 detects the input of a video signal for only one of the first signal input unit 110-1 and the second signal input unit 110-2. In this case, the display processing unit 130 processes the video signal input to either the first signal input unit 110-1 or the second signal input unit 110-2 by using the video processing circuit 132. , The video based on the video signal is displayed in full screen in the display area (video display unit 134) of the video display device 10.
　また、信号検出部１２０が、第１の信号入力部１１０－１および第２の信号入力部１１０－２の双方について映像信号の入力を検出したとする。この場合、表示処理部１３０は、第１の信号入力部１１０－１の位置と、第２の信号入力部１１０－２の位置との関係に基づいて、各映像信号に基づく各映像の表示位置を決定する。図４の例では、第１の信号入力部１１０－１および第２の信号入力部１１０－２は、それぞれ、映像表示装置１０の左の側面および右の側面に設けられている。この場合、表示処理部１３０は、図４に例示されるように、映像表示部１３４の左半分の領域（第１の信号入力部１１０－１が設けられている面側の領域）を、第１の信号入力部１１０－１に入力されている映像信号（Ａ）に基づく映像（Ａ）を表示させる領域として決定する。つまり、表示処理部１３０は、第１の信号入力部１１０－１に入力される映像信号（Ａ）に基づく映像（Ａ）の表示サイズを、映像表示部１３４の左半分の大きさとする。また、表示処理部１３０は、図４に例示されるように、映像表示部１３４の右半分の領域（第２の信号入力部１１０－２が設けられている面側の領域）を、第２の信号入力部１１０－２に入力されている映像信号（Ｂ）に基づく映像（Ｂ）を表示させる領域として決定する。つまり、表示処理部１３０は、第２の信号入力部１１０－２に入力される映像信号（Ｂ）に基づく映像（Ｂ）の表示サイズを、映像表示部１３４の右半分の大きさとする。そして、表示処理部１３０は、映像処理回路１３２を用いて映像信号（Ａ）および映像信号（Ｂ）を処理し、映像（Ａ）および映像（Ｂ）を、各映像について決定された表示位置および表示サイズで表示させる。 Further, it is assumed that the signal detection unit 120 detects the input of video signals for both the first signal input unit 110-1 and the second signal input unit 110-2. In this case, the display processing unit 130 displays the display position of each video based on each video signal based on the relationship between the position of the first signal input unit 110-1 and the position of the second signal input unit 110-2. To determine. In the example of FIG. 4, the first signal input unit 110-1 and the second signal input unit 110-2 are provided on the left side surface and the right side surface of the video display device 10, respectively. In this case, as illustrated in FIG. 4, the display processing unit 130 sets the left half area of the video display unit 134 (the area on the surface side where the first signal input unit 110-1 is provided). It is determined as an area to display the image (A) based on the image signal (A) input to the signal input unit 110-1 of 1. That is, the display processing unit 130 sets the display size of the video (A) based on the video signal (A) input to the first signal input unit 110-1 to the size of the left half of the video display unit 134. Further, as illustrated in FIG. 4, the display processing unit 130 has a second area on the right half of the image display unit 134 (a region on the surface side where the second signal input unit 110-2 is provided). It is determined as an area to display the image (B) based on the image signal (B) input to the signal input unit 110-2 of. That is, the display processing unit 130 sets the display size of the video (B) based on the video signal (B) input to the second signal input unit 110-2 to the size of the right half of the video display unit 134. Then, the display processing unit 130 processes the video signal (A) and the video signal (B) using the video processing circuit 132, and displays the video (A) and the video (B) at the display position and the display position determined for each video. Display in display size.
　本図に例示されるように、２つ以上の信号入力部１１０それぞれにソース機器２０が接続されており、当該２つ以上の信号入力部１１０に対して映像信号の入力があった場合、各映像の表示位置が、各ソース機器２０が接続されている信号入力部１１０の位置に基づいて自動的に決定される。これにより、ユーザ（例えば、ミーティングの参加者等）は、ピクチャー・バイ・ピクチャー形式で複数の映像を表示させる際の煩わしい画面位置設定を行う必要がなくなる。 As illustrated in this figure, when the source device 20 is connected to each of the two or more signal input units 110 and the video signal is input to the two or more signal input units 110, each The display position of the image is automatically determined based on the position of the signal input unit 110 to which each source device 20 is connected. This eliminates the need for the user (for example, a meeting participant or the like) to perform troublesome screen position setting when displaying a plurality of images in a picture-by-picture format.
　また、図６の例では、表示処理部１３０は、第１の信号入力部１１０－１に入力された映像信号に基づく映像および第２の信号入力部１１０－２に入力された映像信号に基づく映像を、ピクチャー・バイ・ピクチャー形式で表示領域に表示しているが、いずれか一方の映像を子画面として表示する、所謂ピクチャー・イン・ピクチャー形式で表示領域に表示させてもよい。また、図６は、２つの信号入力部１１０を映像表示装置１０の左右に設け、表示領域を２つに分割して表示させる例が示されているが、本発明はこれに限定されない。例えば、映像表示装置１０の４つのコーナーの周辺に１つずつ、合計４つの信号入力部１１０が設けられていてもよい。この場合、表示処理部１３０は、映像表示部１３４の表示領域のうち、映像信号が入力された信号入力部１１０の近傍の１／４の領域に、当該映像信号に基づく映像を表示させるように構成されていてもよい。 Further, in the example of FIG. 6, the display processing unit 130 is based on the video signal input to the first signal input unit 110-1 and the video signal input to the second signal input unit 110-2. Although the image is displayed in the display area in the picture-by-picture format, one of the images may be displayed in the display area in the so-called picture-in-picture format in which one of the images is displayed as a sub screen. Further, FIG. 6 shows an example in which two signal input units 110 are provided on the left and right sides of the video display device 10 and the display area is divided into two to display, but the present invention is not limited thereto. For example, a total of four signal input units 110 may be provided, one around each of the four corners of the video display device 10. In this case, the display processing unit 130 causes the display area of the video display unit 134 to display the video based on the video signal in 1/4 of the area near the signal input unit 110 to which the video signal is input. It may be configured.

Hereinafter, such a signal input unit 110 is also referred to as a “specific signal input unit”. It is preferable that the signal input unit 110 that functions as the specific signal input unit and the other signal input units 110 are provided on different surfaces. In the example of FIG. 6, the first signal input unit 110-1, which is a specific signal input unit, is the other signal input unit 110 (second signal input unit 110-2, third signal input unit 110-3, and The fourth signal input unit 110-4) is provided on a surface different from the surface on which the fourth signal input unit 110-4) is provided.

　プロセッサ１０２０は、メモリ１０３０またはストレージデバイス１０４０に記憶されている信号検出部１２０および表示処理部１３０のプログラムモジュールを実行し、信号検出部１２０の機能および表示処理部１３０の機能を実現する。信号検出部１２０は、４つの映像入力検出部１２２それぞれの映像信号の捕捉結果から、第１の信号入力部１１０－１、第２の信号入力部１１０－２、第３の信号入力部１１０－３および第４の信号入力部１１０－４に対する映像信号の入力を検出する。表示処理部１３０は、例えば次のように動作する。 The processor 1020 executes the program modules of the signal detection unit 120 and the display processing unit 130 stored in the memory 1030 or the storage device 1040, and realizes the functions of the signal detection unit 120 and the function of the display processing unit 130. The signal detection unit 120 is based on the acquisition results of the video signals of each of the four video input detection units 122, that is, the first signal input unit 110-1, the second signal input unit 110-2, and the third signal input unit 110-. The input of the video signal to the 3rd and 4th signal input units 110-4 is detected. The display processing unit 130 operates as follows, for example.
　まず、信号検出部１２０が、第１の信号入力部１１０－１、第２の信号入力部１１０－２、第３の信号入力部１１０－３および第４の信号入力部１１０－４のいずれか１つについて映像信号の入力を検出したとする。この場合、表示処理部１３０は、第１の信号入力部１１０－１、第２の信号入力部１１０－２、第３の信号入力部１１０－３および第４の信号入力部１１０－４のいずれか１つに入力された映像信号に基づく映像を映像処理回路１３２を用いて処理し、映像表示装置１０の表示領域（映像表示部１３４）に全画面表示させる。 First, the signal detection unit 120 is one of the first signal input unit 110-1, the second signal input unit 110-2, the third signal input unit 110-3, and the fourth signal input unit 110-4. It is assumed that the input of a video signal is detected for one of them. In this case, the display processing unit 130 is any of the first signal input unit 110-1, the second signal input unit 110-2, the third signal input unit 110-3, and the fourth signal input unit 110-4. The video based on the video signal input to one of them is processed by the video processing circuit 132, and is displayed in full screen in the display area (video display unit 134) of the video display device 10.

Set to a hierarchy below the display hierarchy of the video based on. For example, the display processing unit 130 sets the display layer of the video (A) to the lowest layer. Then, the display processing unit 130 displays the video (A) based on the video signal (A) input to the first signal input unit 110-1 on the entire screen in the display area (video display unit 134) of the video display device 10. Display. In the example of FIG. 6, the video signal (A) is a video signal of an image (for example, an image having a pattern similar to the wall surface around the image display device 10) that makes it difficult to recognize the presence of the display. The video signal provided by the first source device 20-1 is not limited to the example of FIG. The video signal provided from the first source device 20-1 may be a video signal of a signage video such as an advertisement, an art work, or a timetable related to some product or service. As illustrated in FIG. 6, the display processing unit 130 displays the video (A) based on the video signal (A) in the entire display area of the video display device 10. Then, the display processing unit 130 sets the display positions of the video (B), the video (C), and the video (D) in an area near the position of the signal input unit 110 corresponding to each. Further, the display processing unit 130 includes a video (B) based on the video signal (B) input to the second signal input unit 110-2 and a video signal (C) input to the third signal input unit 110-3. ), And the display layer of the image (D) based on the image signal (D) input to the fourth signal input unit 110-4, is higher than the display layer of the image (A). Set to. Then, as illustrated in FIG. 6, the display processing unit 130 places the video (B), the video (C), and the video (D) at positions determined according to the position of the corresponding signal input unit 110, so-called picture. -Display as an in-picture format on top of the image (A).
　本具体例の構成によれば、ソース機器の所有者は、映像表示装置１０に設けられた複数の信号入力部１１０のいずれかに映像信号を入力する際、煩わしい設定を行わなくとも、そのソース機器から出力される映像を自身の前方に表示させることができる。 According to the configuration of this specific example, when the owner of the source device inputs a video signal to any of the plurality of signal input units 110 provided in the video display device 10, the source device does not need to make complicated settings. The image output from the device can be displayed in front of itself.
　なお、特定信号入力部以外の信号入力部１１０（第２の信号入力部１１０－２、第３の信号入力部１１０－３および第４の信号入力部１１０－４）の配置は、図６の例に制限されない。例えば、第２の信号入力部１１０－２、第３の信号入力部１１０－３および第４の信号入力部１１０－４は、例えば、映像表示装置１０の左右の面または上部の面に配置されていてもよい。この場合も、これらの信号入力部１１０に入力された映像信号に基づく映像は、各信号入力部１１０の位置の近傍に表示される。 The arrangement of the signal input unit 110 (second signal input unit 110-2, third signal input unit 110-3, and fourth signal input unit 110-4) other than the specific signal input unit is shown in FIG. Not limited to examples. For example, the second signal input unit 110-2, the third signal input unit 110-3, and the fourth signal input unit 110-4 are arranged, for example, on the left and right surfaces or the upper surface of the video display device 10. You may be. Also in this case, the video based on the video signal input to these signal input units 110 is displayed in the vicinity of the position of each signal input unit 110.

　本具体例における映像表示装置１０は、３つの信号入力部１１０（第１の信号入力部１１０－１、第２の信号入力部１１０－２および第３の信号入力部１１０－３）を有している。第１の信号入力部１１０－１は、映像表示装置１０の左側の面に備えられている。また、第２の信号入力部１１０－２は、映像表示装置１０の右側の面に備えられている。また、第３の信号入力部１１０－３は、映像表示装置１０の背面に備えられている。本具体例において、第３の信号入力部１１０－３は、上述の「特定信号入力部」に相当する。第３の信号入力部１１０－３に入力された映像信号に基づく映像は、映像表示装置１０の表示領域の全体に表示される。 The video display device 10 in the present embodiment has three signal input units 110 (first signal input unit 110-1, second signal input unit 110-2, and third signal input unit 110-3). ing. The first signal input unit 110-1 is provided on the left side surface of the video display device 10.

The second video input detection unit 122-2 captures the video signal input via the second signal input unit 110-2. The third video input detection unit 122-3 captures the video signal input via the third signal input unit 110-3.
　プロセッサ１０２０は、メモリ１０３０またはストレージデバイス１０４０に記憶されている信号検出部１２０および表示処理部１３０のプログラムモジュールを実行し、信号検出部１２０の機能および表示処理部１３０の機能を実現する。信号検出部１２０は、４つの映像入力検出部１２２それぞれの映像信号の捕捉結果から、第１の信号入力部１１０－１、第２の信号入力部１１０－２および第３の信号入力部１１０－３に対する映像信号の入力を検出する。表示処理部１３０は、例えば次のように動作する。 The processor 1020 executes the program modules of the signal detection unit 120 and the display processing unit 130 stored in the memory 1030 or the storage device 1040, and realizes the functions of the signal detection unit 120 and the function of the display processing unit 130. The signal detection unit 120 has the first signal input unit 110-1, the second signal input unit 110-2, and the third signal input unit 110- based on the acquisition results of the video signals of each of the four video input detection units 122. The input of the video signal for 3 is detected. The display processing unit 130 operates as follows, for example.
　まず、信号検出部１２０が、第１の信号入力部１１０－１、第２の信号入力部１１０－２、第３の信号入力部１１０－３および第４の信号入力部１１０－４のいずれか１つについて映像信号の入力を検出したとする。この場合、表示処理部１３０は、第１の信号入力部１１０－１、第２の信号入力部１１０－２、第３の信号入力部１１０－３および第４の信号入力部１１０－４のいずれか１つに入力された映像信号に基づく映像を映像処理回路１３２を用いて処理し、映像表示装置１０の表示領域（映像表示部１３４）に全画面表示させる。 First, the signal detection unit 120 is one of the first signal input unit 110-1, the second signal input unit 110-2, the third signal input unit 110-3, and the fourth signal input unit 110-4. It is assumed that the input of a video signal is detected for one of them. In this case, the display processing unit 130 is any of the first signal input unit 110-1, the second signal input unit 110-2, the third signal input unit 110-3, and the fourth signal input unit 110-4. The video based on the video signal input to one of them is processed by the video processing circuit 132, and is displayed in full screen in the display area (video display unit 134) of the video display device 10.

The viewing angle changing unit 136 is configured to be able to change the viewing angle of the image displayed on the image display unit 134 by electrical control. For example, the viewing angle changing unit 136 is configured to change the orientation of the liquid crystal molecules according to the applied voltage. The display processing unit 130 controls the orientation of the liquid crystal molecules by applying a voltage to the viewing angle changing unit 136, and can freely switch the viewing angle of the image displayed on the image display unit 134.
　例えば、特定信号入力部である第３の信号入力部１１０－３にのみ映像信号が入力されているとする。この場合、表示処理部１３０は、ソース機器２０から入力される映像信号に基づく映像の視野角の制御（視野角の制限）を行なわず、当該映像を広視野角の状態で表示させる（例：図１０）。図１０は、図８の第３の信号入力部１１０－３（特定信号入力部）にのみ映像信号が入力された場合の映像の視野角を例示する図である。図１０の例において、映像を視認可能な範囲は、斜線部で示されている。図１０に例示されるように、映像表示装置１０の前方に存在する複数の人々が、ソース機器２０から入力される映像信号に基づく映像を視認可能となる。 For example, it is assumed that the video signal is input only to the third signal input unit 110-3, which is the specific signal input unit. In this case, the display processing unit 130 does not control the viewing angle (limitation of the viewing angle) of the image based on the image signal input from the source device 20, and displays the image in a state of a wide viewing angle (example:). FIG. 10). FIG. 10 is a diagram illustrating a viewing angle of a video when a video signal is input only to the third signal input unit 110-3 (specific signal input unit) of FIG. In the example of FIG. 10, the visible range of the image is indicated by the shaded area. As illustrated in FIG. 10, a plurality of people existing in front of the video display device 10 can visually recognize the video based on the video signal input from the source device 20.
　また、特定信号入力部ではない、第１の信号入力部１１０－１および第２の信号入力部１１０－２のいずれか一方にのみ映像信号が入力されている場合、表示処理部１３０は、映像信号が入力されている信号入力部１１０の位置に基づいて映像の視野角を制御する。例えば、第１の信号入力部１１０－１にのみ映像信号が入力されているとする。この場合、表示処理部１３０は、第１の信号入力部１１０－１の位置（映像表示装置１０の左側）に基づいて、視野角変更部１３６に印加する電圧を調整し、画面左側方向にのみ映像が見えるように映像の視野角を制御する（例：図１１）。図１１は、図８の第１の信号入力部１１０－１にのみ映像信号が入力された場合の映像の視野角を例示する図である。図１１の例において、映像を視認可能な範囲は、斜線部で示されている。図１１に例示されるように、映像表示装置１０の左側に位置する人物のみが表示領域に表示される映像を視認可能となる。また例えば、第２の信号入力部１１０－２にのみ映像信号が入力されているとする。この場合、表示処理部１３０は、第２の信号入力部１１０－２の位置（映像表示装置１０の右側）に基づいて、視野角変更部１３６に印加する電圧を調整し、画面右側方向にのみ映像が見えるように映像の視野角を制御する（例：図１２）。図１２は、図８の第２の信号入力部１１０－２にのみ映像信号が入力された場合の映像の視野角を例示する図である。図１１の例において、映像を視認可能な範囲は、斜線部で示されている。図１２に例示されるように、映像表示装置１０の右側に位置する人物のみが表示領域に表示される映像を視認可能となる。 Further, when the video signal is input to only one of the first signal input unit 110-1 and the second signal input unit 110-2, which is not the specific signal input unit, the display processing unit 130 displays video. The viewing angle of the image is controlled based on the position of the signal input unit 110 to which the signal is input. For example, it is assumed that the video signal is input only to the first signal input unit 110-1. In this case, the display processing unit 130 adjusts the voltage applied to the viewing angle changing unit 136 based on the position of the first signal input unit 110-1 (left side of the image display device 10), and adjusts the voltage applied to the viewing angle changing unit 136 only in the left side direction of the screen. The viewing angle of the image is controlled so that the image can be seen (example: FIG. 11). FIG. 11 is a diagram illustrating a viewing angle of a video when a video signal is input only to the first signal input unit 110-1 of FIG. 8. In the example of FIG. 11, the visible range of the image is indicated by the shaded area. As illustrated in FIG. 11, only a person located on the left side of the image display device 10 can visually recognize the image displayed in the display area. Further, for example, it is assumed that the video signal is input only to the second signal input unit 110-2. In this case, the display processing unit 130 adjusts the voltage applied to the viewing angle changing unit 136 based on the position of the second signal input unit 110-2 (on the right side of the image display device 10), and adjusts the voltage applied to the viewing angle changing unit 136 only in the right direction of the screen. The viewing angle of the image is controlled so that the image can be seen (example: FIG. 12). FIG. 12 is a diagram illustrating a viewing angle of a video when a video signal is input only to the second signal input unit 110-2 of FIG. In the example of FIG. 11, the visible range of the image is indicated by the shaded area. As illustrated in FIG. 12, only a person located on the right side of the image display device 10 can visually recognize the image displayed in the display area.
　あるユーザが映像表示装置１０の信号入力部１１０（特定信号入力部でない信号入力部１１０）にソース機器２０を接続する場合、そのユーザは、基本的に、その信号入力部１１０の配置面側に位置することなる。そのため、本具体例の構成によれば、ソース機器２０の映像信号を入力したユーザのみが映像を視認可能となる。その結果、他人による映像の覗き見等を防いで、ユーザのプライバシーを保護できる。 When a user connects the source device 20 to the signal input unit 110 (signal input unit 110 that is not a specific signal input unit) of the video display device 10, the user is basically on the side of the arrangement surface of the signal input unit 110. Will be located. Therefore, according to the configuration of this specific example, only the user who has input the video signal of the source device 20 can visually recognize the video. As a result, it is possible to protect the privacy of the user by preventing another person from peeping at the image.
　なお、第１の信号入力部１１０－１、第２の信号入力部１１０－２および第３の信号入力部１１０－３のうちの２つ以上に映像信号が入力されていない場合、表示処理部１３０は、上述したような映像の視野角の制御を行わない。一方で、表示処理部１３０は、他の具体例で述べたように、映像信号が入力されている信号入力部１１０の位置に基づいて、各映像の表示位置や表示サイズを決定する。 If no video signal is input to two or more of the first signal input unit 110-1, the second signal input unit 110-2, and the third signal input unit 110-3, the display processing unit. The 130 does not control the viewing angle of the image as described above. On the other hand, as described in another specific example, the display processing unit 130 determines the display position and display size of each video based on the position of the signal input unit 110 to which the video signal is input.
　上記で挙げた具体例では、映像表示装置１０の外周面のうち少なくとも２つの異なる面に、それぞれ、１つ以上の信号入力部１１０が設けられている。このような信号入力部１１０の配置によれば、ソース機器２０を接続する位置によって、映像がどのように表示されるかがわかりやすくなる。複数のソース機器２０からの映像を同時に表示させる場合、ユーザは、煩わしい設定作業を行うことなく、自分の位置に対応する信号入力部１１０にソース機器２０を接続するだけで、好ましい位置に映像を表示させることができる。 In the specific example given above, one or more signal input units 110 are provided on at least two different surfaces of the outer peripheral surface of the video display device 10. With such an arrangement of the signal input unit 110, it becomes easy to understand how the image is displayed depending on the position where the source device 20 is connected. When displaying images from a plurality of source devices 20 at the same time, the user can display the images at a preferable position simply by connecting the source device 20 to the signal input unit 110 corresponding to his / her position without performing troublesome setting work. It can be displayed.
　以上、本実施形態では、複数の映像信号が同時に映像表示装置１０に入力された場合、各映像信号が入力されている信号入力部１１０の位置に基づいて、各映像の表示態様が自動的に最適化される。これにより、複数の映像を表示領域に同時に表示させる際、ユーザが煩わしい設定を行う必要がなくなる。 As described above, in the present embodiment, when a plurality of video signals are simultaneously input to the video display device 10, the display mode of each video is automatically set based on the position of the signal input unit 110 to which each video signal is input. Optimized. This eliminates the need for the user to make complicated settings when displaying a plurality of images in the display area at the same time.

The first signal input unit 310-1 and the second signal input unit 310-2 are connectors for inserting a cable, a wireless dongle, or the like for connecting the video display device 30 and a source device (not shown). The first signal input unit 310-1 and the second signal input unit 310-2 each support various types of video input / output interface standards. For example, the first signal input unit 310-1 and the second signal input unit 310-2 have various interfaces such as HDMI (registered trademark) (High-Definition Multimedia Interface), DisplayPort, and DVI (Digital Visual Interface), respectively.

　＜処理の流れ＞
　図１４は、第２実施形態の映像表示装置３０により実行される処理の流れを例示するフローチャートである。 <Processing flow>
FIG. 14 is a flowchart illustrating the flow of processing executed by the video display device 30 of the second embodiment.
　信号検出部３２０は、第１の信号入力部３１０－１および第２の信号入力部３１０－２それぞれと電気的に接続されており、第１の信号入力部３１０－１および第２の信号入力部３１０－２それぞれに対する映像信号の入力状態を監視している（Ｓ２０２、Ｓ２０４）。信号検出部３２０は、第１の信号入力部３１０－１および第２の信号入力部３１０－２の少なくとも一方について映像信号の入力を検出すると（Ｓ２０４：ＹＥＳ）、映像信号が入力されている信号入力部を示す情報を表示処理部３３０に通知する（Ｓ２０６）。これは、図３のＳ１０２～Ｓ１０６の処理と同様である。 The signal detection unit 320 is electrically connected to the first signal input unit 310-1 and the second signal input unit 310-2, respectively, and the first signal input unit 310-1 and the second signal input unit 320 The input state of the video signal for each of the units 310-2 is monitored (S202, S204). When the signal detection unit 320 detects the input of a video signal for at least one of the first signal input unit 310-1 and the second signal input unit 310-2 (S204: YES), the signal to which the video signal is input Information indicating the input unit is notified to the display processing unit 330 (S206). This is the same as the processing of S102 to S106 of FIG.
　次に、表示処理部３３０は、信号検出部３２０による映像信号の検出結果に基づいて、映像信号が入力されている信号入力部を識別する（Ｓ２０８）。 Next, the display processing unit 330 identifies the signal input unit to which the video signal is input based on the detection result of the video signal by the signal detection unit 320 (S208).
　第１の信号入力部３１０－１にのみ映像信号が入力されている場合（Ｓ２０８：第１の信号入力部）、表示処理部３３０は、横長表示の解像度を示すＥＤＩＤ（Extended Display Identification Data）を、第１の信号入力部３１０－１に接続されているソース機器２０に対して送信する（Ｓ２１２）。ソース機器２０は、映像表示装置１０から受信したＥＤＩＤによって識別される解像度（横長表示の解像度）に従って、映像信号を映像表示装置１０に送信する。表示処理部３３０は、ソース機器２０から入力される映像信号に基づいて、横長の映像を表示領域の全体に表示させる（例：図１５）。 When the video signal is input only to the first signal input unit 310-1 (S208: first signal input unit), the display processing unit 330 outputs an EDID (Extended Display Identification Data) indicating the resolution of the horizontally long display. , Is transmitted to the source device 20 connected to the first signal input unit 310-1 (S212). The source device 20 transmits the video signal to the video display device 10 according to the resolution (resolution of the horizontally long display) identified by the EDID received from the video display device 10. The display processing unit 330 displays a horizontally long image in the entire display area based on the image signal input from the source device 20 (example: FIG. 15).
　図１５は、第２実施形態の映像表示装置３０による表示の具体例を示す図である。図１５の例では、第１の信号入力部３１０－１は、映像表示装置３０の左側の面（映像表示装置３０の短辺方向の面）に設けられており、第２の信号入力部３１０－２は、映像表示装置３０の上側の面（映像表示装置３０の長辺方向の面）に設けられている。また、図１５では、映像表示装置３０の短辺方向に設けられた第１の信号入力部３１０－１にのみソース機器２０が接続されている状態が描かれている。この場合、表示処理部３３０は、ソース機器２０から入力される映像信号に基づく映像（Ａ）を、図中の矢印の方向（映像表示装置３０の短辺方向）を縦方向として表示させる。 FIG. 15 is a diagram showing a specific example of display by the video display device 30 of the second embodiment. In the example of FIG. 15, the first signal input unit 310-1 is provided on the left side surface of the video display device 30 (the surface in the short side direction of the video display device 30), and the second signal input unit 310 is provided. -2 is provided on the upper surface of the image display device 30 (the surface in the long side direction of the image display device 30). Further, in FIG. 15, a state in which the source device 20 is connected only to the first signal input unit 310-1 provided in the short side direction of the video display device 30 is drawn. In this case, the display processing unit 330 displays the video (A) based on the video signal input from the source device 20 with the direction of the arrow in the drawing (the short side direction of the video display device 30) as the vertical direction.
　第２の信号入力部３１０－２にのみ映像信号が入力されている場合（Ｓ２０８：第２の信号入力部）、表示処理部３３０は、縦長表示の解像度を示すＥＤＩＤを、第２の信号入力部３１０－２に接続されているソース機器２０に対して送信する（Ｓ２１４）。ソース機器２０は、映像表示装置１０から受信したＥＤＩＤによって識別される解像度（縦長表示の解像度）に従って、映像信号を映像表示装置１０に送信する。表示処理部３３０は、ソース機器２０から入力される映像信号に基づいて、縦長の映像を表示領域の全体に表示させる（例：図１６）。 When the video signal is input only to the second signal input unit 310-2 (S208: second signal input unit), the display processing unit 330 inputs the EDID indicating the resolution of the vertically long display to the second signal input unit. It is transmitted to the source device 20 connected to the unit 310-2 (S214). The source device 20 transmits the video signal to the video display device 10 according to the resolution (resolution of the vertically long display) identified by the EDID received from the video display device 10. The display processing unit 330 displays a vertically long image in the entire display area based on the image signal input from the source device 20 (example: FIG. 16).
　図１６は、第２実施形態の映像表示装置３０による表示の他の具体例を示す図である。図１６の例では、映像表示装置３０は、図１５の状態から左に９０度回転させられている。また、ソース機器２０は、第１の信号入力部３１０－１ではなく、第２の信号入力部３１０－２に接続されている。この場合、表示処理部３３０は、ソース機器２０から入力される映像信号に基づく映像（Ａ）を、図中の矢印の方向（映像表示装置３０の長辺方向）を縦方向として表示させる。 FIG. 16 is a diagram showing another specific example of display by the video display device 30 of the second embodiment. In the example of FIG. 16, the image display device 30 is rotated 90 degrees to the left from the state of FIG. Further, the source device 20 is connected to the second signal input unit 310-2 instead of the first signal input unit 310-1. In this case, the display processing unit 330 displays the video (A) based on the video signal input from the source device 20 with the direction of the arrow in the drawing (the long side direction of the video display device 30) as the vertical direction.
　また、第１の信号入力部３１０－１および第２の信号入力部３１０－２の両方に映像信号が入力されている場合（Ｓ２０８：両方）、表示処理部３３０は、対象の信号入力部（表示領域に表示させる映像の映像信号が入力されている信号入力部）の選択状態を確認する（Ｓ２１０）。第１の信号入力部３１０－１が「対象の信号入力部」として選択されている場合（Ｓ２１０：第１の信号入力部）、表示処理部３３０は、横長表示の解像度を示すＥＤＩＤを第１の信号入力部３１０－１に接続されているソース機器２０に対して送信し、横長の映像を表示領域の全体に表示させる（Ｓ２１２、Ｓ２１４）。また、第２の信号入力部３１０－２が「対象の信号入力部」として選択されている場合（Ｓ２１０：第２の信号入力部）、表示処理部３３０は、縦長表示の解像度を示すＥＤＩＤを、第２の信号入力部３１０－２に接続されているソース機器２０に対して送信し、縦長の映像を表示領域の全体に表示させる（Ｓ２１４，Ｓ２１６）。 When a video signal is input to both the first signal input unit 310-1 and the second signal input unit 310-2 (S208: both), the display processing unit 330 is the target signal input unit ( Check the selection status of the signal input unit) to which the video signal of the video to be displayed in the display area is input (S210). When the first signal input unit 310-1 is selected as the "target signal input unit" (S210: first signal input unit), the display processing unit 330 first uses an EDID indicating the resolution of the landscape display. It is transmitted to the source device 20 connected to the signal input unit 310-1 of the above, and a horizontally long image is displayed in the entire display area (S212, S214). When the second signal input unit 310-2 is selected as the "target signal input unit" (S210: second signal input unit), the display processing unit 330 displays an EDID indicating the resolution of the vertically long display. , It is transmitted to the source device 20 connected to the second signal input unit 310-2, and the vertically long image is displayed in the entire display area (S214, S216).

In this case, the display processing unit 330 transmits an EDID indicating a vertically long resolution to the source device 20 connected to the second signal input unit 310-2. The source device 20 outputs a video signal (A) of a vertically long video based on the EDID acquired from the video display device 30. The display processing unit 330 processes the video signal (A) using the video processing circuit 332 to display the vertically long video on the video display unit 334 (display area).
　本実施形態の構成によれば、第１の信号入力部３１０－１または第２の信号入力部３１０－２にソース機器２０を接続した場合に、映像を横長で表示させるか縦長で表示させるかが、自動的に決定される。これにより、ソース機器２０の所有者は、映像表示装置１０の画面を回転させた場合に、煩わしい画面設定（横長表示／縦長表示の設定切替等）を行わなくてもよい。 According to the configuration of the present embodiment, when the source device 20 is connected to the first signal input unit 310-1 or the second signal input unit 310-2, whether to display the image horizontally or vertically. Is automatically determined. As a result, the owner of the source device 20 does not have to perform troublesome screen settings (switching between landscape display / portrait display settings, etc.) when the screen of the video display device 10 is rotated.
　＜信号入力部の位置＞
　第１の信号入力部３１０－１や第２の信号入力部３１０－２の好適な位置について、図１８および図１９を用いて説明する。図１８は、第１の信号入力部３１０－１の好適な位置の一例を示す図である。図１９は、第２の信号入力部３１０－２の好適な位置の一例を示す図である。図１８に例示されるように、第１の信号入力部３１０－１は、好ましくは、映像表示装置３０の短辺方向を映像表示装置３０の設置面に対して垂直にした場合に、当該短辺方向の面（図１８の例では、左側の面）の半分より下側の位置に配置される。また、図１９に例示されるように、第２の信号入力部３１０－２は、好ましくは、映像表示装置３０の長辺方向を３０の設置面に対して垂直にした場合に、当該長辺方向の面（図１９の例では左側の面）の半分より下側の位置に配置される。このような配置とすることで、映像表示装置３０の画面を横向きあるいは縦向きに回転させた場合に、それぞれの信号入力部にソース機器２０を接続し易くなる。 <Position of signal input section>
Suitable positions of the first signal input unit 310-1 and the second signal input unit 310-2 will be described with reference to FIGS. 18 and 19. FIG. 18 is a diagram showing an example of a suitable position of the first signal input unit 310-1. FIG. 19 is a diagram showing an example of a suitable position of the second signal input unit 310-2. As illustrated in FIG. 18, the first signal input unit 310-1 preferably has the short side direction of the video display device 30 perpendicular to the installation surface of the video display device 30. It is arranged at a position below half of the side surface (the left surface in the example of FIG. 18).
