Description

【0080】
記憶部15に格納されている制御プログラムは、表示装置2での多画面機能を実現するための端末機器側制御機能と、表示部11の画面の全部又は一部をキャプチャすることのできる画面キャプチャ機能と、画面キャプチャ機能によって取得されたキャプチャ画像データを表示装置2の表示部21の形式に変換する画像変換機能と、表示部11の画面上の変化を検出する機能を実現するためのもので、該制御プログラムとCPUとによってデータ管理処理部18、画面キャプチャ処理部19、画像変換部19a、画面比較処理部20が構成されている。
[0080]
The control program stored in the storage unit 15 is a terminal device side control function for realizing the multi-screen function in the display device 2 and a screen capture capable of capturing all or part of the screen of the display unit 11 A function, an image conversion function of converting captured image data acquired by the screen capture function into a format of the display unit 21 of the display device 2, and a function of detecting a change on the screen of the display unit 11 The data management processing unit 18 , the screen capture processing unit 19 , the image conversion unit 19a , and the screen comparison processing unit 20 are configured by the control program and the CPU.

【0081】
制御部16は、接続要求、表示要求、拡大表示要求、単画面切替要求、消去要求などの各種要求をユーザインタフェース部14または通信部17を介して受け取り、その要求内容に応じた処理を行うとともに、画面キャプチャ処理部19で取得されたキャプチャ画像データを画像変換部19で変換させ、変換後のキャプチャ画像データを通信部17から表示装置2に送信させる処理などを行う。
[0081]
The control unit 16 receives various requests such as a connection request, a display request, an enlarged display request, a single screen switching request, and an erasure request via the user interface unit 14 or the communication unit 17 and performs processing according to the contents of the request. The capture image data acquired by the screen capture processing unit 19 is converted by the image conversion unit 19a , and the converted capture image data is transmitted from the communication unit 17 to the display device 2 and the like.

【0083】
なお、画像変換部19で行われる変換処理は、以下に詳述するが表示装置2で多画面表示を行うに際し必要な処理であり、具体的には自端末機器1に割り当てられた分割画面の表示サイズへのサイズ変換処理と、表示装置2の表示部21の表示色数への色変換処理である。このように、端末機器1では、画面キャプチャ処理部19で取得されたキャプチャ画像データに対し、表示装置2での多画面表示に必要な変換処理を行ってから表示装置2に送信するように構成される。
[0083]
The conversion processing performed by the image converting unit 19 a is a necessary process upon will be described below performs the multi-screen display on the display device 2, split screen specifically assigned to the own terminal device 1 The size conversion process to the display size of the above and the color conversion process to the number of display colors of the display unit 21 of the display device 2 are performed. As described above, the terminal device 1 is configured to transmit the captured image data acquired by the screen capture processing unit 19 after performing conversion processing necessary for multi-screen display on the display device 2. Be done.

【0129】
端末機器1aの制御部16は、表示装置2から送信されてくるキャプチャ開始指示と表示状況管理ファイル34とを通信部17を介して受信し(S31)、表示状況管理ファイル34の自端末機器1aのキャプチャ範囲指定フラグを参照する(S32)。ここでは「0」であるので(S33)、全画面キャプチャと判断して画面キャプチャ処理部19に全画面キャプチャを指示する。全画面キャプチャの指示を受けた画面キャプチャ処理部19は、ビデオメモリ12の内容(すなわち、現在、表示部11の表示画面に表示されている内容)を例えばビットマップなどの形式で記憶部15に格納する(全画面キャプチャ処理)(S34)。
[0129]
The control unit 16 of the terminal device 1a receives the capture start instruction transmitted from the display device 2 and the display status management file 34 via the communication unit 17 (S31), and the terminal device 1a of the display status management file 34 The capture range designation flag of is referred to (S32). Here, since it is “0” (S33), it is determined that the screen is full screen capture, and the screen capture processing unit 19 is instructed to perform full screen capture. The screen capture processing unit 19 having received the full screen capture instruction stores the contents of the video memory 12 (that is, the contents currently displayed on the display screen of the display unit 11) in the storage unit 15 in the form of a bitmap, for example. Store (full screen capture process) (S34).

【0131】
一方、ステップS33において、キャプチャ範囲管理フラグが「1」である場合には、部分キャプチャと判断して例えば「キャプチャ範囲を指定してください」などのメッセージを示すキャプチャ範囲指定指示画面が表示部11に表示される(S38)とともに、画面キャプチャ処理部19に部分キャプチャが指示される。そして、キャプチャ範囲指定指示画面を確認したユーザによってウィンドウの選択や、所望の領域を囲む操作などが入力部13を介して行われると、画面キャプチャ処理部19は、ユーザインタフェース部14を介してユーザ操作を認識し、指定された領域に対応するビデオメモリ12上の画像データとその画像サイズを記憶部15に格納する(部分キャプチャ処理)(S39)。
[0131]
On the other hand, if the capture range management flag is "1" in step S33, it is determined that a partial capture and a capture range designation instruction screen showing a message such as "Please specify a capture range" is displayed on the display unit 11 Is displayed on the screen (S38), and the screen capture processing unit 19 is instructed to perform partial capture. When the user who has confirmed the capture range specification instruction screen performs window selection or an operation surrounding the desired area via the input unit 13, the screen capture processing unit 19 receives the user via the user interface unit 14. The operation is recognized, and the image data on the video memory 12 corresponding to the designated area and the image size thereof are stored in the storage unit 15 (partial capture process) (S39).
