A case of connection will be described.
　この図において、映像信号発生装置１００は、プライマリモニタに対応する映像信号を表示装置１０１に供給し、セカンダリディスプレイに対応する映像信号を表示装置３００に供給する。映像信号発生装置２００は、プライマリモニタに対応する映像信号を表示装置２０１に供給し、セカンダリディスプレイに対応する映像信号を表示装置３００に供給する。映像信号発生装置１００、映像信号発生装置２００は、例えば、コンピュータである。 In this figure, the video signal generator 100 supplies a video signal corresponding to the primary monitor to the display device 101 and supplies a video signal corresponding to the secondary display to the display device 300. The video signal generator 200 supplies a video signal corresponding to the primary monitor to the display device 201 and supplies a video signal corresponding to the secondary display to the display device 300. The video signal generator 100 and the video signal generator 200 are, for example, computers.
　表示装置１０１は、映像信号発生装置１００から供給される映像信号を表示する。この表示装置１０１は、映像信号発生装置１００に対するプライマリモニタとして機能する。表示装置２０１は、映像信号発生装置２００から供給される映像信号を表示する。この表示装置２０１は、映像信号発生装置２００に対するプライマリモニタとして機能する。 The display device 101 displays the video signal supplied from the video signal generating device 100. The display device 101 functions as a primary monitor for the video signal generation device 100. The display device 201 displays the video signal supplied from the video signal generation device 200. The display device 201 functions as a primary monitor for the video signal generation device 200.
　表示装置３０１は、映像信号発生装置１００または映像信号発生装置２００から供給される映像信号のうち、どちらの映像信号を表示するかを切り替えることで、いずれか一方の映像信号を表示する。この表示装置３０１は、映像信号発生装置１００と映像信号発生装置２００のセカンダリディスプレイとして共有される。
　表示装置１０１、表示装置２０１、表示装置３０１は、例えば、液晶表示装置である。 The display device 301 displays one of the video signals by switching which one of the video signals supplied from the video signal generating device 100 or the video signal generating device 200 is to be displayed. The display device 301 is shared as a secondary display of the video signal generator 100 and the video signal generator 200.
The display device 101, the display device 201, and the display device 301 are, for example, liquid crystal display devices.
　図３は、表示装置３０１の機能を表す概略ブロック図である。
　表示装置３０１において、インタフェース部３１０は、映像信号発生装置１００と映像信号発生装置２００に接続される。インタフェース部３１０のうち、第１入力部３１１は、映像信号発生装置１００から供給される第１映像信号を入力する。第２入力部３１２は、映像信号発生装置２００から供給される第２映像信号を入力する。 FIG. 3 is a schematic block diagram illustrating functions of the display device 301.
In the display device 301, the interface unit 310 is connected to the video signal generation device 100 and the video signal generation device 200. Of the interface unit 310, the first input unit 311 inputs the first video signal supplied from the video signal generator 100. The second input unit 312 inputs a second video signal supplied from the video signal generator 200.
　第１記憶部３２１は、第１コンピュータから出力される第１映像信号を記憶する。第２記憶部３２２は、第２コンピュータから出力される第２映像信号を記憶する。この第１記憶部３２１、第２記憶部３２２は、それぞれ、例えば、ＶＲＡＭ（Ｖｉｄｅｏ　ＲＡＭ（Ｒａｎｄｏｍ　Ａｃｃｅｓｓ　Ｍｅｍｏｒｙ））を用いることができる。この場合、表示装置３００には、VRAMが2基搭載され、入力が2系統存在するとき、現在表示している映像信号の供給元である映像信号発生装置にかかわらず、常時2台の映像信号発生装置（映像信号発生装置１００、映像信号発生装置２００）から供給されているディスプレイへの映像信号をそれぞれ記憶する。 The first storage unit 321 stores the first video signal output from the first computer. The second storage unit 322 stores the second video signal output from the second computer. Each of the first storage unit 321 and the second storage unit 322 can use, for example, a VRAM (Video RAM (Random Access Memory)). In this case, when the display device 300 has two VRAMs and two inputs, regardless of the video signal generator that is the source of the currently displayed video signal, two video signals are always displayed. Video signals to the display supplied from the generators (video signal generator 100, video signal generator 200) are stored.
　表示部３３０は、映像信号を表示する。この表示部３３０は、例えば、液晶表示パネルであり、制御部３５０からの指示に応じて映像信号を表示する。 Display unit 330 displays a video signal. The display unit 330 is a liquid crystal display panel, for example, and displays a video signal in response to an instruction from the control unit 350.
　検出部３４０は、表示部３３０のうち、前記第１映像発生装置から出力される第１映像信号の映像の少なくとも一部の領域である第１の領域と前記第２映像信号発生装置から出力される第２映像信号の少なくとも一部の領域である第２の領域とのいずれかに、映像の変化があるか否かを検出する。
　制御部３５０は、検出部３４０の検出結果に基づいて、映像の変化が検出された領域に対応する映像信号を表示部３３０に表示する。例えば、制御部３５０は、検出部３４０が第１の領域において映像の変化を検出した場合に第１映像信号を表示部３４０に表示し、検出部３４０が第２の領域において映像の変化を検出した場合に第２映像信号を表示部３４０に表示することができる。 The detection unit 340 is output from the first region which is at least a part of the image of the first video signal output from the first video generation device and the second video signal generation device in the display unit 330. It is detected whether or not there is a video change in any of the second areas that are at least a part of the second video signal.
Based on the detection result of the detection unit 340, the control unit 350 displays a video signal corresponding to the area in which a change in video is detected on the display unit 330. For example, the control unit 350 displays a first video signal on the display unit 340 when the detection unit 340 detects a video change in the first region, and the detection unit 340 detects a video change in the second region. In this case, the second video signal can be displayed on the display unit 340.
　次に、図４は、第１記憶部３２１、第２記憶部３２２に記憶される映像信号を表示部３３０へ供給する概念を説明する概念図である。
　符号４１０は、映像信号発生装置１００から供給され第１記憶部３２１に記憶された第１映像信号に対応した表示画面の概念を表す図（以下、画面表示イメージと称す）であり、符号４２０は、映像信号発生装置２００から供給され第２記憶部３２２に記憶された第２映像信号に対応した表示画面の概念を表す図（以下、画面表示イメージと称す）である。
　また、符号１１０は、表示装置１００の表示画面に表示される映像の概念を表す図であり、符号２１０は、表示装置２００の表示画面に表示される映像の概念を表す図である。 Next, FIG. 4 is a conceptual diagram illustrating the concept of supplying video signals stored in the first storage unit 321 and the second storage unit 322 to the display unit 330.
Reference numeral 410 is a diagram (hereinafter referred to as a screen display image) representing a concept of a display screen corresponding to the first video signal supplied from the video signal generator 100 and stored in the first storage unit 321, and reference numeral 420 is FIG. 3 is a diagram (hereinafter referred to as a screen display image) representing a concept of a display screen corresponding to a second video signal supplied from the video signal generation device 200 and stored in a second storage unit 322.
Reference numeral 110 represents a concept of a video displayed on the display screen of the display device 100, and reference numeral 210 represents a concept of a video displayed on the display screen of the display device 200.
　第１の領域４１１は、映像発生装置１００から出力される第１映像信号の映像の少なくとも一部の領域である。この第１の領域４１１の位置は、例えば、映像発生装置１００から出力されプライマリモニタに表示される映像信号の画面表示イメージと第１映像信号の映像との配置関係によって決めることができる。ここでは、第１映像信号の映像に対し、映像発生装置１００から出力されたプライマリモニタに表示される映像信号の画面表示イメージが左側に配置される位置関係である場合、第１の領域４１１は、第１映像信号の映像のうち、左側の領域に設定される。例えば、画面表示イメージ４１０の４つの辺のうち、図に向かって左側の位置に対応する表示装置１０１の表示画面１１０に隣り合う辺である第１の辺４１２を基準として、表示画面の中央側に向かって定められた距離ｃが離れた位置までを含む範囲の領域が第１領域４１１として設定される。この定められた距離は、例えば、映像の変化を検出する対象のサイズに応じて決められる任意の距離である。 The first area 411 is an area of at least a part of the video of the first video signal output from the video generator 100. The position of the first area 411 can be determined by, for example, the positional relationship between the screen display image of the video signal output from the video generator 100 and displayed on the primary monitor and the video of the first video signal. Here, when the screen display image of the video signal displayed on the primary monitor output from the video generator 100 is positioned on the left side with respect to the video of the first video signal, the first region 411 is In the video of the first video signal, the left side area is set. For example, out of the four sides of the screen display image 410, the first side 412 that is the side adjacent to the display screen 110 of the display device 101 corresponding to the position on the left side in the figure is used as the reference side of the center side of the display screen. A region in a range including a position where the distance c determined toward is separated is set as the first region 411. This determined distance is, for example, an arbitrary distance determined in accordance with the size of the target for detecting a change in video.
　第２の領域４２１は、映像発生装置２００から出力される第２映像信号の映像の少なくとも一部の領域である。この第２の領域４２１の位置は、例えば、映像発生装置２００から出力されプライマリモニタに表示される映像信号の画面表示イメージと第２映像信号の映像との配置関係によって決めることができる。ここでは、第２映像信号の映像に対し、映像発生装置２００から出力されたプライマリモニタに表示される映像信号の画面表示イメージが右側に配置される位置関係である場合、第２の領域４２１は、第２映像信号の映像のうち、右側の領域に設定される。例えば、画面表示イメージ４２０の４つの辺のうち、図に向かって右側の位置に対応する表示装置２０１の表示画面２１０に隣り合う辺である第２の辺４２２を基準として、表示画面の中央側に向かって定められた距離ｄが離れた位置までを含む範囲の領域が第２領域４２１として設定される。この定められた距離は、例えば、映像の変化を検出する対象のサイズに応じて決められる任意の距離である。 The second area 421 is an area of at least a part of the video of the second video signal output from the video generator 200. The position of the second area 421 can be determined by, for example, the positional relationship between the screen display image of the video signal output from the video generator 200 and displayed on the primary monitor and the video of the second video signal. Here, when the screen display image of the video signal displayed on the primary monitor output from the video generator 200 is positioned on the right side with respect to the video of the second video signal, the second region 421 is In the video of the second video signal, it is set to the right region. For example, among the four sides of the screen display image 420, the center side of the display screen is based on the second side 422 that is the side adjacent to the display screen 210 of the display device 201 corresponding to the position on the right side in the figure. A region in a range including a position where the distance d determined toward is separated is set as the second region 421. This determined distance is, for example, an arbitrary distance determined in accordance with the size of the target for detecting a change in video.
　このように、第１の領域４１１や第２の領域４２１は、プライマリモニタ（表示装置１０１あるいは表示装置２０１）に表示される映像とセカンダリモニタ（表示装置３０１）に表示される映像とが隣接する関係にある場合には、その隣接する位置を基準として決めることができる。 As described above, in the first region 411 and the second region 421, the video displayed on the primary monitor (display device 101 or display device 201) and the video displayed on the secondary monitor (display device 301) are adjacent to each other. If there is a relationship, the adjacent position can be determined as a reference.
　映像の変化は、特定の図形の移動によって生じる映像の変化であることが例として上げられる。この映像の変化は、例えば、第１映像信号のうち、映像信号発生装置１００において使用されるマウス等の入力装置によって入力する対象の画面上の位置を示す図形（例えば、マウスカーソル）が、第１の領域内に移動してきたか否か、及び、第２映像信号のうち、映像信号発生装置２００において使用されるマウス等の入力装置によって入力する対象の画面上の位置を示す図形（例えば、マウスカーソル）が、第２の領域内に移動してきたか否かに基づいて、検出部３４０が検出する。ここでは、距離ｃ、距離ｄは、マウスカーソルの幅と同じか、それよりも大きなサイズに対応した距離である。 An example of the change in image is an image change caused by movement of a specific figure. For example, the change in the video is caused by, for example, a graphic (for example, a mouse cursor) indicating a position on a screen to be input by an input device such as a mouse used in the video signal generation device 100 in the first video signal. A graphic (for example, a mouse) indicating whether or not it has moved within the region 1 and the position on the screen of the second video signal to be input by an input device such as a mouse used in the video signal generating device 200 The detection unit 340 detects based on whether or not the cursor has moved into the second area. Here, the distance c and the distance d are distances corresponding to a size equal to or larger than the width of the mouse cursor.
　この場合、マウスカーソルの大きさが、映像信号発生装置１００と映像信号発生装置２００において異なる場合、映像信号発生装置において用いられるそれぞれのカーソルの大きさに応じて距離ｃ、距離ｄを異なる距離とすることができる。すなわち、第１の領域４１１と、第２の領域４２１の大きさは、同じであってもよいし、異なっていてもよい。 In this case, when the size of the mouse cursor is different between the video signal generation device 100 and the video signal generation device 200, the distance c and the distance d are set to different distances depending on the size of each cursor used in the video signal generation device. can do. That is, the size of the first region 411 and the size of the second region 421 may be the same or different.
　このような構成において、検出部３４０は、第１の記憶部３２１に記憶される映像信号のうち第１の領域４１１と、第２の記憶部３２２に記憶される映像信号のうち第２の領域４２１と、をポーリングによって一定時間毎に監視し、この領域内にマウスカーソルの大きさに対応するピクセル分のサイズの変化が現れたか否かを検出することで、第１の領域４１１または第２の領域４２１において映像の変化が生じたことを検出する。ここでは、検出部３４０は、さらに、この映像の変化の方向がプライマリモニタ側からセカンダリディスプレイ側へ移動する方向であるか、セカンダリディスプレイ側からプライマリモニタ側に移動する方向であるかを検出する。例えば、検出部３４０は、第１の領域４１１において、表示装置１０１側から表示装置３０１側に向かってマウスカーソルが移動したか（符号ａ）、表示装置３０１側から表示装置１０１側に向かってマウスカーソルが移動したか（符号ｂ）を検出し、第２の領域４２１において、表示装置２０１側から表示装置３０１側に向かってマウスカーソルが移動したか（符号ｆ）、表示装置３０１側から表示装置２０１側に向かってマウスカーソルが移動したか（符号ｇ）を検出する。 In such a configuration, the detection unit 340 includes the first region 411 in the video signal stored in the first storage unit 321 and the second region in the video signal stored in the second storage unit 322. 421 are monitored at regular intervals by polling, and it is detected whether or not a change in size corresponding to the size of the mouse cursor has appeared in this area, whereby the first area 411 or the second area 421 is detected. It is detected that a video change has occurred in the area 421. Here, the detection unit 340 further detects whether the direction of change of the video is a direction moving from the primary monitor side to the secondary display side or a direction moving from the secondary display side to the primary monitor side. For example, in the first region 411, the detection unit 340 determines whether the mouse cursor has moved from the display device 101 side to the display device 301 side (symbol a) or from the display device 301 side to the display device 101 side. Whether the cursor has moved (symbol b) is detected, and in the second region 421, whether the mouse cursor has moved from the display device 201 side to the display device 301 side (symbol f), or from the display device 301 side to the display device It is detected whether the mouse cursor has moved toward the 201 side (symbol g).
　制御部３５０は、検出部３４０の検出結果に応じて、表示部３３０に表示させる映像信号を、第１記憶部３２１または第２記憶部３２２から読み出し、ソフトウェア上のスイッチ（符号ｅ）を切り替えて、表示部３３０に出力する。例えば、制御部３４０は、検出部３４０が、第１の領域４１１において、表示装置１０１側から表示装置３０１側に向かってマウスカーソルが移動したことを検出した場合には、第１映像信号を表示部３３０に表示させ、表示装置３０１側から表示装置１０１側に向かってマウスカーソルが移動したことを検出した場合には、この検出結果に応じた処理は行わない。また、制御部３５０は、第２の領域４２１において、表示装置２０１側から表示装置３０１側に向かってマウスカーソルが移動したことを検出した場合には、第２映像信号を表示部３３０に表示させ、表示装置３０１側から表示装置２０１側に向かってマウスカーソルが移動した場合には、この検出結果に応じた処理は行わない。これにより、マウスカーソルがプライマリモニタ側からセカンダリディスプレイ側に移動した映像信号発生装置１００または映像信号発生装置２００からの映像信号が表示部３３０に表示される。 The control unit 350 reads a video signal to be displayed on the display unit 330 from the first storage unit 321 or the second storage unit 322 according to the detection result of the detection unit 340, and switches a switch (symbol e) on the software. To the display unit 330. For example, when the detection unit 340 detects that the mouse cursor has moved from the display device 101 side toward the display device 301 side in the first region 411, the control unit 340 displays the first video signal. When it is displayed on the unit 330 and it is detected that the mouse cursor has moved from the display device 301 side toward the display device 101 side, processing according to the detection result is not performed. When the control unit 350 detects that the mouse cursor has moved from the display device 201 side to the display device 301 side in the second region 421, the control unit 350 causes the display unit 330 to display the second video signal. When the mouse cursor moves from the display device 301 side toward the display device 201 side, processing according to the detection result is not performed. As a result, the video signal from the video signal generator 100 or the video signal generator 200 in which the mouse cursor has moved from the primary monitor side to the secondary display side is displayed on the display unit 330.
　ここで、ユーザは、一般に、セカンダリディスプレイで映像の参照や作業をしたい場合、マウスカーソルをプライマリモニタ側からセカンダリディスプレイ側に移動させる。これを利用し、この実施形態においては、２台の映像信号発生装置を表示装置に接続した際、表示装置３０１、ユーザ操作によるマウスカーソルの移動を検知し、マウスカーソルがセカンダリディスプレイ内（表示装置３０１側）に移動してきた方の映像信号発生装置からの映像信号に、自動で表示切替を行う。 Here, the user generally moves the mouse cursor from the primary monitor side to the secondary display side when the user wants to refer to or work on the video on the secondary display. By utilizing this, in this embodiment, when two video signal generators are connected to the display device, the display device 301 detects the movement of the mouse cursor by a user operation, and the mouse cursor is detected in the secondary display (display device). The display is automatically switched to the video signal from the video signal generator that has moved to the (301 side).
　次に、上述した実施形態における表示装置３０１の動作について、図５のフローチャートを用いて説明する。
　表示装置３０１は、映像信号発生装置１００から供給される第１映像信号と映像信号発生装置２００から供給される第２映像信号を入力し（ステップＳ１１）、第１映像信号を第１記憶部３２１に記憶し、第２映像信号を第２記憶部３２２に記憶する（ステップＳ１２）。 Next, the operation of the display device 301 in the above-described embodiment will be described using the flowchart of FIG.
The display device 301 inputs the first video signal supplied from the video signal generator 100 and the second video signal supplied from the video signal generator 200 (step S11), and the first video signal is stored in the first storage unit 321. And the second video signal is stored in the second storage unit 322 (step S12).
　検出部３４０は、第１記憶部３２１に記憶された第１映像信号のうち、所定の領域内において映像の変化があるか否かを検出するとともに、第２記憶部３２２に記憶された第２映像信号のうち、所定の領域内において映像の変化があるか否かを検出する（ステップＳ１３）。 The detection unit 340 detects whether or not there is a video change in a predetermined area from the first video signal stored in the first storage unit 321, and also stores the second video stored in the second storage unit 322. In the video signal, it is detected whether or not there is a video change within a predetermined area (step S13).
　検出部３４０は、いずれかの所定の領域内において映像の変化があったことを検出した場合、その変化した映像の移動方向が、プライマリモニタ側からセカンダリディスプレイ側への移動方向であるか否かを検出する（ステップＳ１４）。制御部３５０は、変化した映像の移動方向が、プライマリモニタ側からセカンダリディスプレイ側への移動方向である場合、その変化が生じた映像信号の供給元からの映像信号へ切り替えを行う（ステップＳ１５）。そして、制御部３４０は、表示を終了する指示が表示装置３０１に入力されたか否かを判定し、表示終了の指示が入力された場合には、表示部３３０への表示を終了し、表示終了の指示が入力されていなければ、ステップＳ１１に移行する。 When the detection unit 340 detects that the video has changed in any of the predetermined areas, whether or not the moving direction of the changed video is the moving direction from the primary monitor side to the secondary display side. Is detected (step S14). When the moving direction of the changed video is the moving direction from the primary monitor side to the secondary display side, the control unit 350 switches to the video signal from the video signal supply source in which the change has occurred (step S15). . Then, the control unit 340 determines whether or not an instruction to end the display is input to the display device 301. When the display end instruction is input, the control unit 340 ends the display on the display unit 330 and ends the display. If the instruction is not input, the process proceeds to step S11.
　一方、ステップＳ１３において、検出部３４０が映像の変化がないことを検出した場合、制御部３５０は、現在と同じ供給元からの映像信号を表示（切り替えしない）する（ステップＳ１７）。また、ステップＳ１４において、検出部３４０が映像の変化がプライマリモニタ側からセカンダリディスプレイ側への移動方向ではないことを検出した場合、現在と同じ供給元からの映像信号を表示（切り替えしない）する（ステップＳ１７）。 On the other hand, when the detection unit 340 detects that there is no video change in step S13, the control unit 350 displays (does not switch) the video signal from the same supply source as the present (step S17). In step S14, when the detection unit 340 detects that the change in the video is not the moving direction from the primary monitor side to the secondary display side, the video signal from the same supply source as the current source is displayed (not switched) ( Step S17).
　上述した第１の実施形態および第２の実施形態によれば、２台の映像信号発生装置のセカンダリディスプレイとして使用されている表示装置が、ユーザが現在どちらの映像信号発生装置を使用した作業をしているかを判別し、その表示を使用している映像信号発生装置側に、手動によってスイッチ等を切り替えることなく、表示の切り替えを行うことができる。また、この第１の実施形態および第２の実施形態によれば、ハードスイッチ（物理的なスイッチ）を切り替える必要がないので、スイッチ自体が使用と共に劣化し、正しい切り替えが不可能となる場合を防止することもできる。 According to the first embodiment and the second embodiment described above, the display device used as the secondary display of the two video signal generators can be operated by the user using either of the video signal generators. It is possible to switch the display without manually switching the switch or the like to the video signal generating apparatus using the display. Further, according to the first and second embodiments, there is no need to switch the hard switch (physical switch), and therefore the switch itself deteriorates with use, and correct switching is impossible. It can also be prevented.
　また、上述した第２の実施形態によれば、映像の変化が、セカンダリディスプレイ側からプライマリディスプレイ側への移動方向である場合には、映像信号の切り替えを行わないようにしたので、セカンダリディスプレイを用いた作業をしている際に、マウスカーソルをプライマリディスプレイ側に移動させた場合における誤切替を防止することができる。 Further, according to the second embodiment described above, when the change in the video is the moving direction from the secondary display side to the primary display side, the video signal is not switched. It is possible to prevent erroneous switching when the mouse cursor is moved to the primary display side during the work used.
　なお、上述の第１の実施形態または第２の実施形態において、セカンダリディスプレイに第１映像が表示され、かつ、第１の映像信号発生装置からの映像信号に基づくカーソルがセカンダリディスプレイに存在する場合において、第２の映像信号発生装置からの映像信号に基づくカーソルが、セカンダリディスプレイ側に移動したことが検出された場合、制御部３５０は、第１の映像信号の表示から第２の映像信号の表示に切り替えることができる。 In the first embodiment or the second embodiment described above, the first video is displayed on the secondary display, and the cursor based on the video signal from the first video signal generator is present on the secondary display. When it is detected that the cursor based on the video signal from the second video signal generator has moved to the secondary display side, the control unit 350 starts the display of the second video signal from the display of the first video signal. You can switch to display.
　また、上述した第１の実施形態および第２の実施形態における構成は、映像信号発生装置が３台以上であり、表示装置が映像信号発生装置よりも１台以上多い台数であっても、適用することができる。 The configurations in the first and second embodiments described above are applicable even when the number of video signal generators is three or more and the number of display devices is one or more than that of video signal generators. can do.
　上述した実施形態における表示装置１または表示装置３０１の機能をコンピュータで実現するようにしてもよい。その場合、こ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、実行することによって実現してもよい。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んでもよい。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よく、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よく、ＦＰＧＡ（Field Programmable Gate Array）等のプログラマブルロジックデバイスを用いて実現されるものであってもよい。 The functions of the display device 1 or the display device 301 in the above-described embodiment may be realized by a computer. In that case, a program for realizing this function may be recorded on a computer-readable recording medium, and the program recorded on this recording medium may be read into a computer system and executed. Here, the “computer system” includes an OS and hardware such as peripheral devices. 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 inside a computer system serving as a server or a client in that case may be included and a program held for a certain period of time. Further, the program may be a program for realizing a part of the above-described functions, and may be a program capable of realizing the functions described above in combination with a program already recorded in a computer system. It may be realized using a programmable logic device such as an FPGA (Field Programmable Gate Array).
