Extended Graphics Array Wide (四邊外擴充式圖形陣列寬）：3840X2400像素）及QUXGA (Quad Ultra Extended Graphics Array(四邊夕f 擴式圖开多陣歹[J ):3200 X 24 00像素）等高精細、高像素數之液晶監視器的 圖像顯示裝置（以下，稱爲「監視器」（monitor))已見諸開 發、販售，可將非常大量之資訊量的圖像資訊，作高精細 之顯示。 在該顯示畫面成超高精細化之同時，亦須使輸出圖像資 料側之個人電腦（下稱"PC”）的處理能力提升，在考量對應 超高解像度時，勢必作電腦圖形（computer graphics)之複雜 計算。惟一般之P C無法充分對應，因此，乃須製作一種專 用之P C ’以對應超高解像度作圖像處理，此種超高解像度 對應型之P C，價格非常昂貴，難以供一般之使用。 習用技術中，例如專利文獻1，係把複數台之控制裝置（P C) 作並聯連接，以實行分散、並聯處理，而成爲一種系統。 -6- 1281118 % 亦即，在該種系統中，係把複數之PC連接在網路（network) 中，各個PC均以共同方式安裝而成，或是用個別之方式， 構築爲一個圖像及一個動作畫面。該構築之圖像’係在連 接於各個PC之監視器上顯示，該等監視器之構成，係配列 成”田”字型，所顯示之圖像，全體係成一個大的圖像。 專利文獻1 :特開平8-305485號公報（第1-4頁，第1圖）。 (三）發明內容： 發明擬解決之問題 但是，上述習用之系統，僅連接一個由鍵盤、滑鼠所構 成之主PC，而其他的伺服PC，則係輸入經由主PC、來自 屬於輸入裝置之鍵盤/滑鼠的指示輸入資訊而構成。因此， 在實行具有例如主PC之圖像處理等較大負荷之處理時，其 他伺服PC上，即無法輸出該指示輸入資訊，則鍵盤/滑鼠 之操作即遲緩，依處理之狀態而言，乃產生了操作停頓之 問題。又，倘主P C之電源爲切斷狀態時，亦有全體系統均 停止之問題。 此外，PC之OS(OperatingSystem)爲不同，網路協定 (network protocol)亦各不同，故亦有無法構築系統之網路 問題。 因此，乃須考量設置一般P C以外之專用p c，用以處理 指示輸入資訊，則除了增加製造成本外，尙須專用之設置 場所，再者，亦有系統之耗用電力變大之問題。 本發明即鑑諸以上問題，而提供一種圖像顯示控制方法 、圖像顯示裝置、顯示控制裝置、電腦及圖像顯示控制系 1281118 w 統’可減輕對於依特定之P C之指示輸入資訊的處理負荷， 並可迅速執行輸入裝置之操作。 用以解決問題之方式： 爲了解決上述問題並達成預期目的，本發明係一種把複

(四）實施方式 實施發明之最佳形態 以下，佐以第1〜8圖，具體說明本發明之圖像顯示控制 方法、圖像顯示裝置、顯示控制裝置、電腦及圖像顯示控 制系統之實施例。而本發明並非僅限定爲所舉之實施例， 在不脫離本發明要旨之範圍內，自有各種之變形例。 (第1實施例） 第1圖爲依本發明圖像顯示控制系統所構成一例的構成 圖。在第1圖中，圖像顯示控制系統係由η台（實施例爲4 台）之P C 1 1〜1 4 ;具有液晶模組等監視器2 1之圖像顯示裝 置20;使圖像顯示裝置20連接於該等PC11〜14之通信 控制線3 1〜3 4與視頻信號線4 1〜44 ;屬輸入裝置之1套 鍵盤5 0與滑鼠5 1 ;及令鍵盤5 0與滑鼠5 1連接於圖像顯 示裝置2 0之信號線5 2、5 3所構成。 圖像顯示裝置20係由監視器2 1與顯示控制部22構成， 顯示控制部22具有η個（實施例爲4個）之輸入埠，其組成 包含：PC介面（下稱PC I/F)，可藉由電腦30內之通信控制 線31〜34與PC11〜14作通信；邏輯電路24，可藉由電 纜30內之視頻信號線41〜44,由PCI 1〜14取入視頻信號 ;鍵盤/滑鼠I/F(下稱KBD/MS IF)25，可藉由信號線52、 53而連接於鍵盤50與滑鼠51;及CPU26，可對來自PC I/F23與KBD/MS IF25之輸入信號作信號處理，並對邏輯 -12- 1281118 電路24與圖像顯示裝置20全體施行控制。又，通信控制 線3 1〜34，係例如由USB線、PS/2線及串行電纜（serial cable)等所構成。 CPU26，如上述，係實行來自PC I/F23與KBD/MS IF25 輸入信號之信號處理，鍵盤游標（以下稱游標）係判斷現在 位在哪一個位置。亦即，本實施例中，監視器2 1係對應4 台PCI 1〜14，而把顯示領域作4等分之分割（第1圖參照） ，CPU26則用以判斷在該等4個顯示領域A〜D中，哪一 個顯示領域上具有游標者。又，將來自鍵盤5 0之鍵碼輸入 轉送於PC之際，CPU26可判斷究應轉送於哪一個PC。亦 即，並非轉送於所有的PC。再者，CPU26可依來自PC I/F 23之資訊，進行究應將游標描繪於監視器畫面之何處的計 算，基於計算結果（計算後之座標値），控制邏輯電路24即 可實行描繪。 又，在此處，該監視器之畫面因係分割爲4個顯示領域 ，故游標顯示及鍵盤之按鍵輸入，則以把可能之顯示領域 作爲有源區域較佳，用以驅動該有源區域之P C即稱之爲有 源PC。CPU26可將游標之移動等的資訊與鍵碼之資訊輸 出於有源P C，及取入來自有源P C之游標的座標値。 又，各PC11〜14之OS，係把管理之桌面（desktop)座標 定義爲區域座標，圖像顯示裝置20，則係把管理之畫面座 標（監視器上之座標）定義爲總體（global)座標。該區域座標 與總體座標之變換，可依線性作變換，例如，某PC輸出之 解像度爲（Xc，Yc)，將該解像度由監視器上（X0, Y0)之位置 -13- 1281118 作a倍之顯示時，X座標變爲（區域座標=((總體座標）_ X〇)/a(Y座標亦相同）。 監視器21，係爲1台可同時顯示4台PC11〜14之輸出 圖像，並保持解像度之超高解像度監視器。亦即，監視器 21具有對應於PC11〜14之分割顯示領域A〜D，可將來自 PC 11〜14輸入之輸出圖像，基於邏輯電路24之邏輯控制 ，而可同時顯示在分割之A〜D顯示領域上。 各PC11〜14之構成均相同，第2圖係以PC11爲代表 之槪略構成圖。第2圖所示者，僅爲構成於本發明之部分 ，通常的P C 1 1係具備有：用來輸出視頻信號並驅動圖像顯 示裝置20的圖像系統；用來與圖像顯示裝置20作通信之 埠，例如USB、DDC/CI或者串列埠；以及用以由圖像顯示 裝置20接收鍵盤及滑鼠的信號之埠，例如USB、PS2或者 串列埠。此實施例中，具有分別的KBD/MS驅動器1 5 ;游 標顯示處理部16 ;及鉗夾驅動器（hook drive〇17等。 K B D / M S驅動器1 5，係經由圖像顯示裝置2 0與通信控制 線3 1而接收來自鍵盤5 0之鍵碼信號、來自滑鼠5 1之按鈕 狀態及X、Y方向之移動距離資訊等。 游標顯示處理部1 6，係取入來自KBD/MS驅動器1 5輸 出之滑鼠移動等的資訊，以計算X、Y座標値，在通常之 PC中，游標係描繪所計算之位置，指令（command)即輸出 於描繪系統內之圖像卡驅動器（graphing card driver)，此實 施例中，係輸出於鉗夾驅動器1 7之構成。 鉗夾驅動器1 7係依本發明新穎配設之構成部分，用以鉗 1281118 夾游標顯示處理部1 6所計算之游標的座標値及指繪指令 ，而經由通信控制線3 1輸出於顯示控制部2 2。又，本實 施例中，因描繪指令係由鉗夾驅動器予以鉗夾，故在實際 上，藉描繪系統內之游標驅動器，游標並未顯示於監視上 。該游標係藉上述圖像顯示裝置20之邏輯電路24而作顯 示0 又，鉗夾驅動器1 7，如係接收來自顯示控制部2 2之游 標的座標値設定指令時，顯示控制部22可將該鉗夾驅動器 本身動作之電腦系統的游標位置，移動於指定之位置上。 其次，以第3〜7圖說明游標之顯示控制動作。首先，使 用者在連接於圖像顯示裝置20之各PC11〜14配設（in st all) 以鉗夾驅動器後，將PCI 1〜14與圖像顯示裝置20連接於 通信控制線3 1〜3 4及信號線4 1〜4 4。因此，即啓動了 P C 1 1 〜14及圖像顯示裝置20。 在第3圖中，於啓動時，圖像顯示裝置20之CPU26，圖 中未示之暫存器（register)上，係初期設定初期値或前次最 終狀態之値（步驟1 〇 1 )。又，此一初期値可考量以下之設定 條件： 1 ·作爲有源PC/有源區域者，爲例如第5圖所示A之顯 示領域、有效視頻之輸入的最初顯示領域、依使用者操作 所指定之顯示領域、或預先定義之顯示領域。 2·游標之總量座標（X，Y)者，爲有源區域之中央或預先定 義之位置。 其次，CPU26係取入來自有源PC之資訊（步驟102)，算 -15- 1281118 出監視器2 1上之座標（步驟丨0 3 )，將該座 電路24 ’藉該邏輯電路24以游標顯示該 監視器2 1之顯示控制（步驟1 〇 4)。又，於 P C 1 1〜1 4之紺夾驅動器係檢出游標位置， 送出資訊，C P U 2 6則僅取入來自有源p c v 該CPU26係經常監視KBD/MS I/F25

1 1之游標的顯示控制 功能。在第4圖中，有源PCI 1之KBD/MS驅動器15，係 如有資訊經由圖像顯示裝置20、通信控制線3 1輸入時（步 驟201)，可用以判斷該資訊係屬游標移動等之資訊、滑鼠 按鈕之鍵擊資訊、或鍵碼之資訊。 在此，輸入資訊爲游標移動等資訊的情況時，游標顯示 處理部16即計算來自該移動等之資訊的區域座標（步驟2 03 ) ，例如移動量爲（Δχ，Ay)，原始之座標爲（X，Y)時，新座標 即成爲（X + AxXk，Y + Ayxk)。又，因輸入資訊爲有源區域 C之境界的”E”之座標値，故基於此一座標値即可計算游標 之區域座標。 其次，游標顯示處理部1 6，係基於區域座標而作成描繪 指令（步驟2 04)。作成的新座標係轉送於有源PC，轉送之 資料格式（data form at)則不同。在來自移動量之計算時，因 一般可用KBD/MS驅動器15作支援，故可用該KBD/MS 驅動器作轉送，又，如係作新適用之有源區域之境界的座 標値轉送時，則係使用新導入的鉗夾驅動器作轉送（步驟 205) ° 又，在輸入資訊爲滑鼠按鈕之鍵擊資訊時，KBD/MS驅 動器15乃基於該鍵擊資訊實行信號處理（步驟206)， 將該處理結果輸出於圖像顯示裝置20(步驟207)。又，輸 入資訊如爲在鍵碼之資訊時，KBD/MS驅動器15係基於鍵 擊資訊，實行信號處理（步驟208)，處理結果，則輸出於圖 -17- 1281118 像顯示裝置20(步驟2〇9)。 其次，利用第5〜7圖所示之游標的顯示狀態說明游標之 顯示動作。首先，在第5圖中，使用者僅把游標移動1作 (△X，Ay)之移動時，CPU26即把該移動量（Δχ，Ay)送出於有 源P C 1 1，此時，稱之爲表示座標之數値，不如稱之爲滑鼠 球在X、Y方向任何方向轉動所成之資訊。該資訊並不送 出於無源（in active)之PC，係僅送出於有源PC。有源PC 11 之KB D/MS驅動器15，係計算由原始座標起之新座標値 (X + AxXk，Y + AyXk)。又，k爲設定於OS之係數，該係數 因電腦之不同而有差異。此時，圖像顯示裝置20係預先讀 取k値，組合畫面解像度與顯示倍率，調整Δχ，Ay，亦可 令監視器2 1上之游標1的移動速度爲一定。 該新座標値可用鉗夾驅動器1 7予以鉗夾住，經通信控制 線31送出於圖像顯示裝置20。此時，CPU26係進行游標1 是否於現在的有源區域內移動之檢查，倘在現在的有源區 域內，乃控制邏輯電路24而實行游標1之描繪。又，把游 標1移動於現在有源區域之境界、且在將Δχ，Ay在超越該 境界之方向作增減時，使用者可嚐試作跨越顯示領域之移 動（參照第6圖）。 CPU26檢知游標有跨越顯示領域之移動後，有源PC爲 現在之有源P C 1 1，游標座標係如第6圖所示，位於有源區 域A之境界，在此，CPU26係把有源PCI 1與有源區域A 變更爲有源PC13與有源區域C。因此，乃把新有源PCI 3 中之游標1的座標値（’’ E ”之座標値）經通信控制線3 3送出 -18- 1281118 於鉗夾驅動器1 7並設定之。依此’即可達成跨越顯 後游標之移動。 此處，顯示於監視器2 1畫面上之游標1就算是 各PC也必須注意保持「看不見」游標。亦即，倘 圖所示，游標1移動於顯示領域C後，P C 1 1爲，游 停止於’’E”之座標値的狀態。但是，CPU26因係未把 資訊送出有源P C以外’故顯示領域C在有源之間 把在顯示領域A之游標資訊送出’結果’ 「看不見 標不論是位於顯示領域A之何處也不會被顯示所以 響。 另，如第7圖所示，倘游標再返回顯示領域A之 ，游標1並非移動於’’E”之位置，而彳系移動於”F”之 的位置。此時，因爲鍵盤5 0之輸入焦點（用以表示 被送於哪一個顯示領域之設定）甚爲明確，故可將成 P C之顯示領域返回爲無源狀態。爲此，乃將游標由 域逸出之狀況通知鉗夾驅動器並設定，鉗夾驅動器 顯示領域以無源狀態通知設定〇S。 或是，CPU26亦可爲，游標在新的有源區域中一 滑鼠51之按鈕鍵擊，一旦鍵擊輸入之焦點乃爲移動 況者，而無源命令則可送出於在此之前有源P C之紺 器。 又，在各P C均保持聲音輸出之機能時，則僅有源 PC的聲音輸出機能方爲ON狀態，使聲音輸出之，；1281118 发明, invention description: (1) Technical field to which the invention belongs: The present invention relates to an

(Fourth Embodiment) BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an image display control method, an image display device, a display control device, a computer, and an image display control system according to the present invention will be specifically described with reference to FIGS. 1 to 8. example. The present invention is not limited to the embodiments, and various modifications are possible without departing from the spirit and scope of the invention. (First Embodiment) Fig. 1 is a configuration diagram showing an example of an image display control system according to the present invention. In Fig. 1, the image display control system is composed of n 1 (four in the embodiment) PC 1 1 to 1 4; an image display device 20 having a monitor 2 such as a liquid crystal module; The device 20 is connected to the communication control lines 3 1 to 34 of the PCs 11 to 14 and the video signal lines 4 1 to 44; a set of keyboards 50 and 5 1 of the input device; and the keyboard 50 and the mouse 5 1 is connected to the signal lines 5 2, 5 3 of the image display device 20 . The image display device 20 is composed of a monitor 21 and a display control unit 22. The display control unit 22 has n (four in the embodiment) input ports, and the composition thereof includes a PC interface (hereinafter referred to as PC I/F). The communication control lines 31 to 34 in the computer 30 can communicate with the PCs 11 to 14; the logic circuit 24 can capture the video signals from the PCI 1 to 14 by the video signal lines 41 to 44 in the cable 30; / Mouse I/F (hereinafter referred to as KBD/MS IF) 25, which can be connected to the keyboard 50 and the mouse 51 by signal lines 52, 53; and the CPU 26 can be used for the PC I/F 23 and the KBD/MS IF 25 The input signal is signal processed and the logic-12-1281118 circuit 24 and the image display device 20 are all controlled. Further, the communication control lines 3 1 to 34 are constituted by, for example, a USB cable, a PS/2 line, a serial cable or the like. The CPU 26, as described above, performs signal processing from the input signals of the PC I/F 23 and the KBD/MS IF 25, and the keyboard cursor (hereinafter referred to as a cursor) determines which position is currently located. That is, in the present embodiment, the monitor 2 1 corresponds to four PCIs 1 to 14, and the display field is divided into four equal parts (refer to FIG. 1), and the CPU 26 is used to determine the four display fields. Among the A to D, which one has a cursor on the display field. Further, when the key code input from the keyboard 50 is transferred to the PC, the CPU 26 can determine which PC to transfer to. That is, it is not transferred to all PCs. Furthermore, the CPU 26 can perform calculations on where the cursor should be drawn on the monitor screen based on the information from the PC I/F 23, and based on the calculation result (the calculated coordinate 値), the control logic circuit 24 can perform the rendering. . Moreover, here, the screen of the monitor is divided into four display areas, so the cursor display and the key input of the keyboard are preferably used as the active area to drive the active area. The PC is called an active PC. The CPU 26 can output information such as the movement of the cursor and the information of the key code to the active P C and take in the coordinates of the cursor from the active P C . Further, the OS of each of the PCs 11 to 14 defines the desktop of the management as the area coordinates, and the image display device 20 defines the coordinates of the management (the coordinates on the monitor) as the global coordinates. . The transformation of the coordinates of the area and the overall coordinates can be changed according to linearity. For example, the resolution of a PC output is (Xc, Yc), and the resolution is a times the position of -13-1281118 on the monitor (X0, Y0). In the display, the X coordinate becomes (area coordinate = ((total coordinates) _ X 〇) / a (Y coordinates are also the same). The monitor 21 is one output image of four PCs 11 to 14 can be simultaneously displayed. And the super-high resolution monitor that maintains the resolution. That is, the monitor 21 has the divided display areas A to D corresponding to the PCs 11 to 14, and the output images from the PCs 11 to 14 can be input based on the logic of the logic circuit 24. Control, and can be displayed simultaneously in the divided A to D display fields. The configuration of each of PCs 11 to 14 is the same, and the second figure is a schematic diagram represented by PC11. The second figure is only for the configuration. In part of the present invention, a conventional PC 1 1 is provided with an image system for outputting a video signal and driving the image display device 20; for communicating with the image display device 20, such as USB, DDC/CI Or a serial port; and a keyboard and a mouse for receiving by the image display device 20 The number is, for example, USB, PS2 or serial port. In this embodiment, there are separate KBD/MS drivers 15; cursor display processing unit 16; and jaw driver (hook drive〇17, etc. KBD / MS driver 1 5, receiving the key code signal from the keyboard 50, the button state from the mouse 51, the moving distance information in the X and Y directions, and the like via the image display device 20 and the communication control line 31. The cursor display processing unit 1 6 is to take in information from the mouse movement of the KBD/MS driver 105 output to calculate the X and Y coordinates. In a normal PC, the cursor draws the calculated position, and the command outputs. The drawing card driver in the drawing system, in this embodiment, is outputted from the jaw driver 17. The jaw driver 17 is a novel component of the present invention for clamping 1281118 The cursor cursor displays the coordinates of the cursor calculated by the processing unit 16 and the pointing command, and outputs it to the display control unit 2 via the communication control line 31. Further, in the present embodiment, the drawing command is performed by the jaw driver. Clamping, so in practice The cursor is not displayed on the monitor by the cursor driver in the drawing system. The cursor is displayed by the logic circuit 24 of the image display device 20, and the clamp driver 17 receives the control from the display. When the coordinate setting instruction of the cursor of the part 2 2 is set, the display control unit 22 can move the cursor position of the computer system in which the jaw driver itself operates to the designated position. Next, the cursor display is described in the third to seventh figures. Control action. First, the user connects (in St all) the PCs 11 to 14 connected to the image display device 20 to clamp the driver, and then connects the PCIs 1 to 14 and the image display device 20 to the communication control lines 3 1 to 3 . 4 and signal line 4 1~4 4. Therefore, P C 1 1 to 14 and the image display device 20 are activated. In Fig. 3, at the time of startup, the CPU 26 of the image display device 20, which is not shown in the register, is initially set to the initial state or the previous final state (step 1 〇 1). In addition, the initial setting conditions can be considered as follows: 1. As an active PC/active area, for example, the display area of A shown in FIG. 5, the initial display area of the input of the effective video, and the operation by the user. The specified display area, or a predefined display area. 2. The total coordinate (X, Y) of the cursor is the center of the active area or a predefined position. Next, the CPU 26 takes in the information from the active PC (step 102), calculates the coordinates of the -15-1281118 on the monitor 2 1 (step 丨0 3 ), and borrows the logic circuit 24 from the block circuit 24'. The display control of the monitor 2 1 is displayed (step 1 〇 4). In addition, the PC 1 1~1 4 clip drive detects the cursor position and sends the information, and the CPU 26 only takes in the active pcv. The CPU 26 constantly monitors the KBD/MS I/F25 keyboard 50 and the mouse. 5 1 indicates the input information (when the step indicates the input information, it is judged to be the keystroke (c 1 ick) information of the mouse button such as the cursor movement, or the key code _ 〇 if the input information is indicated as the movement of the cursor, etc. If the user moves the cursor to the same display and only moves to (Δχ, Ay), it is sent to PCI 1 via the communication control line 3 i (step 1〇7). Again, as the sixth one puts the cursor When moving from different display area A to C, the 'E' is the coordinate of the "E" in the PC 1 1 whose position of the cursor is active. Here, the CPU 26 is changed from the PC 11 to the PC 13 or the active area is displayed by the display C, and the coordinates of the cursor 値 "E" are sent to the new key and the input information such as the button of the mouse button is hit. It is sent out of the active pc 1 1 (step 1 〇 8 ), and if it is the key code information from the keyboard 50, the keyboard PC 11 (step 1 〇 9). Therefore, the CPU 26 returns to the PC to take in the information. : The standard is output to the logical coordinate 値, and when P C is started, all the information is via the communication control line. , the judgment is from 1 〇 5). If there is information about the finger, or is slipping (step 106), that is, as in the field A of Figure 5, for example, the moving amount map is shown, and if used, the active pc domain A is now used. 5) (when the system changes the active PC display area A to the source PC 1 3 ° information, this button indicates that the input information system is sent out from the active step 102, from the active-16-1281118. The display control function of the cursor of the PC 1 1 is illustrated by the flowchart of Fig. 4. In Fig. 4, the KBD/MS driver 15 of the active PCI 1 is provided with information via the image display device 20, and communication control. When the line 3 1 is input (step 201), it may be used to determine that the information is information such as cursor movement, keystroke information of the mouse button, or key code information. Here, when the input information is information such as cursor movement or the like The cursor display processing unit 16 calculates an area coordinate from the information such as the movement (step 2 03 ), for example, the movement amount is (Δχ, Ay), and when the original coordinate is (X, Y), the new coordinate becomes (X). + AxXk, Y + Ayxk). Also, because the input information is the "E" of the realm of the active area C The standard coordinates of the cursor can be calculated based on the standard mark. Next, the cursor display processing unit 16 creates a drawing command based on the area coordinates (step 2 04). The created new coordinate is transferred to the active PC. The data form at the transfer is different. In the calculation of the movement amount, the KBD/MS driver 15 can be used for support, so the KBD/MS driver can be used for transfer, and if the system is newly applicable. When the coordinates of the realm of the active area are transferred, the newly imported clamp driver is used for transfer (step 205). Further, when the input information is the keystroke information of the mouse button, the KBD/MS driver 15 is based on the The keystroke information is subjected to signal processing (step 206), and the processing result is output to the image display device 20 (step 207). Further, when the input information is the information of the key code, the KBD/MS driver 15 is based on the keystroke information. Signal processing is performed (step 208), and the processing result is output to the image display device 20 of Fig. -17-1281118 (step 2〇9). Next, the display state of the cursor is illustrated by the display state of the cursor shown in Figs. action First, in Fig. 5, when the user moves only the cursor by 1 (ΔX, Ay), the CPU 26 sends the amount of movement (Δχ, Ay) to the active PC 1 1, at this time, To represent the number of coordinates, it is better to call the information that the mouse ball rotates in any direction in the X and Y directions. This information is not sent to the active PC, but only to the active PC. The KB D/MS driver 15 of the active PC 11 calculates a new coordinate 値 (X + AxXk, Y + AyXk) from the original coordinates. Also, k is a coefficient set to the OS, and the coefficient varies depending on the computer. At this time, the image display device 20 reads k値 in advance, combines the screen resolution and the display magnification, adjusts Δχ, Ay, and makes the moving speed of the cursor 1 on the monitor 21 constant. The new coordinate can be clamped by the jaw driver 17 and sent to the image display device 20 via the communication control line 31. At this time, the CPU 26 checks whether or not the cursor 1 is moved in the current active area, and controls the logic circuit 24 to perform the drawing of the cursor 1 in the current active area. Further, when the cursor 1 is moved to the realm of the active area, and when Δχ, Ay is increased or decreased in the direction beyond the boundary, the user can attempt to move across the display area (see Fig. 6). After the CPU 26 detects that the cursor has moved across the display area, the active PC is the active PC 1 1 , and the cursor coordinate system is located in the realm of the active area A as shown in FIG. 6, where the CPU 26 is active. PCI 1 and active area A are changed to active PC 13 and active area C. Therefore, the coordinate 値 (the coordinate of the ''E') of the cursor 1 in the new active PCI 3 is sent out to the jaw driver 17 via the communication control line 3 3 and set. The movement of the cursor after the display can be achieved. Here, the cursor 1 displayed on the screen of the monitor 21 must be kept in an "invisible" cursor even if it is a PC. That is, as shown in the figure, after the cursor 1 moves in the display area C, the PC 1 1 is in a state in which the cursor stops at the coordinate of the 'E'. However, the CPU 26 does not send the information out of the active PC. The display field C sends the cursor information in the display field A between the actives. The result is "not visible." If the cursor returns to display area A, cursor 1 does not move to the position of ''E', and the line moves to the position of "F". At this time, since the input focus of the keyboard 50 (which is used to indicate which display area is set) is clear, the display area of the P C can be returned to the passive state. For this reason, the cursor is notified to the jaw driver by the state of the escape of the field, and the clamp driver display field is set to 〇S by the passive state notification. Alternatively, the CPU 26 may also be a button click of the cursor 51 in the new active area, once the focus of the keystroke input is a mobile condition, and the passive command may be sent out before being active. PC device. Moreover, when each of the P C functions to maintain the sound output, only the sound output function of the source PC is turned ON, and the sound is outputted;

Accordingly, in this embodiment, the user has a plurality of pcs, but still operates like a PC. If so, the processing load of the input information for the specific PC can be reduced, and thus the input device can be quickly operated. . Moreover, with this embodiment, the image display device uses the automatically selected PC as the active PC of the jaw driver, and only the active PC is used as the coordinate of the cursor. Since the cursor can be displayed, only the entire monitor is displayed. A cursor is displayed so that the input device can be operated quickly. Moreover, with this embodiment, only the source PC constitutes a related cursor display. Since each PC is completely independent, the processing load for instructing input information to a specific PC can be alleviated, and even if there is a power cut of a certain PC. Broken, other PCs are not affected, so it can prevent the entire system from stopping. In addition, in this embodiment, since the PCs are completely independent, if the OSs used by the PCs are different, the network of the system can also be constructed. Further, since the program of the image display control method is not large in scale and hardly depends on the OS/application, a program can be constructed. Moreover, in this embodiment, the CPU is configured to detect the active PC, and the cursor is displayed in the corresponding display field, and thus the present invention is compared with the situation in which the user uses the dedicated PC. The composition is simple, reduces manufacturing costs, and reduces system power consumption. (Second Embodiment) In the first embodiment, the present invention is not limited to the calculation of the coordinates of the cursor on the P C side, and the calculation can be performed on the image display control side. Hereinafter, the operation of the image display device -20-1281118 will be described with reference to the flowchart of Fig. 8. The CPU 26 constantly monitors the status of the KBD/MS I/F 25 and determines whether or not there is instruction input information from the keyboard 50 and the mouse 51 (step 3〇1). If the instruction input information is used, it is determined that the instruction input information is M cursor movement or the like, or is a keystroke information of the mouse, or a key code, etc. (step 3 02). Here, the status of the input information such as the movement of the cursor is indicated, that is, as shown in FIG. 5, the user only places the cursor in the same display area a, for example, when (Δχ, Ay) moves, When the coordinates of the original cursor are (X, γ), the new coordinate 値 (total coordinates) becomes (X + AxXkl, Y + Ay X 1) (step 3 03 ). Further, k 1 is a coefficient set in the image display device. Next, the CPU 26 converts the new coordinate to the area coordinate 有源 on the active PC 1 (step 3 04) and outputs it to the active PCI 1 (step 305). Also, in this case, the coordinates of this area are not output to other PCs. Moreover, if the input information is indicated as the keystroke information of the mouse, the keystroke information is sent out to the active PC (step 3 06), and when the input information is indicated as the information from the key code of the keyboard 50, The key code information is sent to the active PCI 1 (step 3 0 8). Therefore, the CPU 26 returns to step 301 to execute the instruction input information from the keyboard 50 and the mouse 51. The clamp driver 17 of the active PCI 1 moves the cursor to this coordinate when receiving a new coordinate 値 (area coordinate). However, since the display of the cursor is not performed by P C, the cursor is not drawn at this point in time. At this time, the CPU 26 can be used to check the movement condition of the cursor in the current active area A - 21 - 1281118, as shown in Fig. 5, when moving in the current active area A, the control logic circuit 24 can be used to describe the cursor 1. Further, when the cursor 1 moves over the realm of the current active area and the movement thereof crosses the realm, the user can try to move across the field (see Fig. 6). When the CPU 20 detects that there is a cursor moving across the display area, the active PC is the current active P C 1 1, and the cursor coordinates are as shown in Fig. 6, at the realm of the active area A. Here, the CPU 26 changes the active PC and the active area to P C 1 3 and display area C. Therefore, the coordinates of the cursor 1 of the new active P C 1 3 (the coordinates of "E") are sent to the jaw driver 17 via the communication control line 3 3 and set. In this way, the cursor can be moved across the display field. In this way, in addition to the same functions as those of the first embodiment, the management of both the movement and the coordinates of the cursor can be performed on the side of the image display device, and the overall control of the cursor action can be performed. The PC side only transmits the information, so that the motion of the cursor can be obtained more smoothly. Further, in this embodiment, the display control unit that performs the display control of the cursor is carried in the image display device, but the present invention is not limited thereto, and the image display device may implement the above-described cursor in another manner. The display control is configured, for example, by connecting a keyboard and a mouse as a display control device. In this case, the same effects as the above embodiments can be obtained. Further, in this embodiment, the cursor display control device provided inside and outside the image display device (excluding the PC) explains the purpose of the display control, and can also be displayed as a cursor on the PC. In this case, the communication of the coordinates of the cursor is performed in the same manner as in the embodiment. In the function of the above-mentioned jaw driver, the display function of the forbidden cursor is released, and the display of the state in the PC is maintained as the standard -22-1281118 state. The function can draw the cursor as video data, thereby obtaining the effect of not requiring the display of the control device.
