In this embodiment, the image analysis unit 300 and the viewing angle adjustment unit 400 are configured on the host 200A, and the host 200A may include a processor 210, such as a central processing unit (Central Processing Unit, CPU), which may be configured on the host 200A. circuit board (not shown). In one embodiment, at least one of the frame analyzing unit 300 and the viewing angle adjusting unit 400 may be integrated into the processor 210 . Alternatively, the image analyzing unit 300 and the viewing angle adjusting unit 400 may be configured separately from the processor 210 and then electrically connected with a transmission line. Alternatively, the image analysis unit 300 and the viewing angle adjustment unit 400 can be integrated into a single component, such as a microcontroller (Microcontroller Unit, MCU), and the microcontroller and the processor 210 are manufactured separately and then configured on the host 200A.

以連接方式來說，比例縮放器130與處理器210之間可採用HDMI(High Definition Multimedia Interface)或DP(Display Port)方式連接，然本發明實施例不以此為限。相似地，比例縮放器130與視場角調整單元400之間也可採用HDMI或DP方式連接。攝像器110與比例縮放器130之間可採用GPIO(General-purpose input/output)或I2C(Inter-Integrated Circuit)方式連接，然本發明實施例不以此為限。 In terms of the connection method, HDMI (High Definition Multimedia Interface) or DP (Display Port) can be used to connect the scaler 130 and the processor 210 , but the embodiment of the present invention is not limited thereto.

The camera 110 and the scaler 130 can be connected by GPIO (General-purpose input/output) or I2C (Inter-Integrated Circuit), but the embodiment of the present invention is not limited thereto.

如第1A圖所示，螢幕100A連接於主機200A並接收由主機200A傳來的一顯示訊號D1並據以顯示一顯示畫面F。在本實施例中，顯示畫面F(顯示畫面F的內容例如是第1B圖之顯示畫面F1及第1C圖之顯示畫面F2)例如是主機200A所載入之程式P1(程式P1繪示於第3A圖)的畫面。螢幕100A包含一攝像器110，攝像器110用以擷取使用者的即時動態畫面M1。畫面分析單元300用以分析即時動態畫面M1的內容，以取得使用者之使用者狀態U1。視場角調整單元400配置在主機200A且用以：依據使用者狀態U1，改變顯示畫面F的視場角。例如，由第1B圖所示之小視場角的顯示畫面F1改變至如第1C圖所示之大視場角的顯示畫面F2，然亦可從第1C圖所示之大視場角的顯示畫面F2改變至第1B圖所示之小視場角的顯示畫面F1。如此，使用者可不需操作任何手動輸入裝置，只需改變使用者狀態U1，即可改變顯示畫面F的視場角。 As shown in FIG. 1A , the screen 100A is connected to the host 200A and receives a display signal D1 from the host 200A to display a display screen F accordingly. In this embodiment, the display screen F (the content of the display screen F is, for example, the display screen F1 in FIG. 1B and the display screen F2 in FIG. 1C ) is, for example, the program P1 loaded in the host computer 200A (the program P1 is shown in FIG. 3A picture). Screen 100A includes a camera The imager 110, the camera 110 is used to capture the real-time dynamic picture M1 of the user. The screen analysis unit 300 is used for analyzing the content of the real-time dynamic screen M1 to obtain the user status U1 of the user. The viewing angle adjustment unit 400 is configured on the host computer 200A and used for: changing the viewing angle of the display screen F according to the user state U1 . For example, the display screen F1 with a small viewing angle shown in Figure 1B is changed to the display screen F2 with a large viewing angle as shown in Figure 1C, but it can also be changed from the display screen with a large viewing angle as shown in Figure 1C The display screen F2 is changed to the display screen F1 with a small viewing angle as shown in FIG. 1B. In this way, the user can change the viewing angle of the display screen F by changing the user state U1 without operating any manual input device.

即時動態畫面M1例如是即時串流動態影像，其為使用者在操作電子裝置10A(如，直播、線上玩電腦遊戲)時攝像器110所拍攝到的畫面，如使用者的特徵及/或動作。USB集線器120與攝像器110及主機200A電性連接，即時動態畫面M1可透過USB集線器120傳輸給位於主機200A之畫面分析單元300。透過USB集線器120電性連接於主機200A之畫面分析單元300，即時動態畫面M1可透過USB集線器120傳輸給位於主機200A之畫面分析單元300。 The real-time dynamic picture M1 is, for example, a real-time streaming dynamic picture, which is a picture captured by the camera 110 when the user operates the electronic device 10A (for example, live broadcasting, playing computer games online), such as the user's characteristics and/or actions . The USB hub 120 is electrically connected to the camera 110 and the host 200A, and the real-time dynamic image M1 can be transmitted to the image analysis unit 300 located in the host 200A through the USB hub 120 . The real-time dynamic image M1 can be transmitted to the image analysis unit 300 located in the host 200A through the USB hub 120 .

在本實施例中，顯示畫面F例如是攝像器110所擷取的前方攝像畫面，例如是即時動態畫面M1。在本實施例中，即時動態畫面M1可供分析使用者狀態U1之用，且即時動態畫面M1的視場角可隨攝像器110之視場角設定而變，視場角改變後之顯示畫面F(如，即時動態畫面M1)可顯示於螢幕100A之顯示面板140。然視場角改變後之顯示畫面F也可輸出至遠端的電子裝置，並選擇性地顯示在遠端電子裝置的顯示面板，以讓遠端電子裝置的使用者觀看到視場角改變(減少或增加對方看到的視野範圍)之顯示畫面F。在實施例中，比例縮放器130可控制顯示面板140的顯示畫面F的尺寸、解析度及/或視場角等。前述顯示訊號D1可由處理器210傳輸給螢幕100A之比例縮放器130，再由比例縮放器130控制顯示面板140依據顯示訊號D1顯示對應的顯示畫面F。 In this embodiment, the display frame F is, for example, a forward camera frame captured by the camera 110 , such as a real-time dynamic frame M1 . In this embodiment, the real-time dynamic picture M1 can be used to analyze the user status U1, and the field of view of the real-time dynamic picture M1 can be changed with the setting of the field of view of the camera 110, and the displayed picture after the field of view is changed F (for example, the real-time dynamic picture M1) can be displayed on the display surface of the screen 100A plate 140. However, the display picture F after the viewing angle is changed can also be output to the remote electronic device, and selectively displayed on the display panel of the remote electronic device, so that the user of the remote electronic device can see the change of the viewing angle ( Reduce or increase the field of view seen by the other party) on the display screen F. In an embodiment, the scaler 130 can control the size, resolution and/or viewing angle of the display frame F of the display panel 140 . The aforementioned display signal D1 can be transmitted from the processor 210 to the scaler 130 of the screen 100A, and then the scaler 130 controls the display panel 140 to display the corresponding display frame F according to the display signal D1.

在一實施例中，使用者狀態U1例如是使用者與攝像器110之間的距離H1及/或使用者的姿態，如臉部、手掌、手臂、頭部及/或身體的至少一部分的靜態姿態或動態姿態。畫面分析單元300在完成使用者狀態U1之分析後，傳送對應使用者狀態U1之訊號S1(表示使用者狀態U1，如距離H1或使用者的姿態)給視場角調整單元400，視場角調整單元400再據以改變或調整顯示畫面F的視場角。 In one embodiment, the user state U1 is, for example, the distance H1 between the user and the camera 110 and/or the posture of the user, such as the static state of at least a part of the face, palm, arm, head and/or body. posture or dynamic posture. After the analysis of the user state U1 is completed, the screen analysis unit 300 sends a signal S1 corresponding to the user state U1 (indicating the user state U1, such as the distance H1 or the user's posture) to the field of view adjustment unit 400, and the field of view The adjustment unit 400 then changes or adjusts the viewing angle of the display picture F accordingly.

以使用者狀態U1為使用者與攝像器110之間的距離H1來說，畫面分析單元300更用以：分析即時動態畫面M1的內容，取得使用者與攝像器110之間的距離H1。視場角調整單元400更用以：依據距離H1，改變攝像器110之視場角參數設定，以改變顯示畫面F的視場角。在本實施例中，改變攝像器110之視場角參數設定ST係由主機200A主動控制，而非由螢幕100A執行。此外，視場角調整單元400可透過或控制比例縮放器130調整或改變攝像器110之視場角參數設定ST。 Taking the user state U1 as the distance H1 between the user and the camera 110 , the frame analysis unit 300 is further used to: analyze the content of the real-time dynamic frame M1 to obtain the distance H1 between the user and the camera 110 . The field of view adjusting unit 400 is further used to: change the field of view parameter setting of the camera 110 according to the distance H1, so as to change the field of view of the display image F. In this embodiment, changing the viewing angle parameter setting ST of the camera 110 is actively controlled by the host computer 200A, rather than being executed by the monitor 100A. In addition, the field of view adjustment unit 400 can pass through or control the scaling The device 130 adjusts or changes the field angle parameter setting ST of the camera 110 .

此外，顯示畫面F之視場角可正比於距離H1。舉例來說，視場角調整單元400更用以：(1).判斷距離H1係漸遠(距離H1變大)或漸近(距離H1變小)；(2).當距離H1係漸遠時，改變攝像器110之視場角參數設定ST，增加顯示畫面F之視場角；以及(3).當距離H1係漸近時，改變攝像器110之視場角參數設定ST，降低顯示畫面F之視場角。例如，當距離H1為80公分時，攝像器110之視場角參數設定ST為90度；當距離H1為75公分時，攝像器110之視場角參數設定ST為80度；當距離H1為85公分時，攝像器110之視場角參數設定ST為100度。 In addition, the viewing angle of the display screen F can be proportional to the distance H1. For example, the viewing angle adjustment unit 400 is further used for: (1). Judging that the distance H1 is getting farther (the distance H1 becomes larger) or asymptotically (the distance H1 is getting smaller); (2). When the distance H1 is getting farther , change the angle of view parameter setting ST of camera 110, increase the angle of view of display screen F; angle of view. For example, when the distance H1 is 80 centimeters, the field angle parameter setting ST of the camera 110 is 90 degrees; when the distance H1 is 75 centimeters, the field angle parameter setting ST of the camera 110 is 80 degrees; when the distance H1 is At 85 cm, the field angle parameter setting ST of the camera 110 is 100 degrees.

在另一實施例中，顯示畫面F之視場角可反比於距離H1。舉例來說，視場角調整單元400用以：當距離H1係漸遠時，改變攝像器110之視場角參數設定ST，降低顯示畫面F之視場角；以及，當距離H1係漸近時，改變攝像器110之視場角參數設定ST，增加顯示畫面F之視場角。 In another embodiment, the viewing angle of the display frame F may be inversely proportional to the distance H1. For example, the viewing angle adjustment unit 400 is used to: change the viewing angle parameter setting ST of the camera 110 to reduce the viewing angle of the display screen F when the distance H1 is getting farther; and, when the distance H1 is getting closer , change the viewing angle parameter setting ST of the camera 110 to increase the viewing angle of the display screen F.

此外，使用者可啟動或關閉視場角調整模式。舉例來說，比例縮放器130更用以：(1).提供對一視場角調整模式之一設定介面SE1；(2).回應由視場角調整模式之設定介面SE1所接收之一視場角調整模式之啟動指令T1，啟動視場角調整模式。啟動指令T1例如是由使用者輸入。設定介面SE1例如是螢幕顯示(On-Screen Display,OSD)介面。在另一實施例，視場角調整模式的設定亦可由一輸入裝置(未繪示)設定，其中輸入裝置例如是電性連接於主機200A之鍵盤及/或滑鼠。比例縮放器130可將視場角調整模式的設定結果通知或傳送給畫面分析單元300、視場角調整單元400及/或處理器210。 In addition, the user can activate or deactivate the field of view adjustment mode. For example, the scaler 130 is further used to: (1). Provide a setting interface SE1 for a field of view adjustment mode; (2). Respond to a view received by the setting interface SE1 of the field of view adjustment mode. The start command T1 of the field angle adjustment mode activates the field angle adjustment mode. The activation command T1 is, for example, input by a user. The setting interface SE1 is, for example, an On-Screen Display (OSD) interface. In another embodiment, the setting of the viewing angle adjustment mode can also be set by an input device (not shown), wherein the input device is, for example, Electrically connected to the keyboard and/or mouse of the host 200A. The scaler 130 may notify or transmit the setting result of the viewing angle adjustment mode to the frame analyzing unit 300 , the viewing angle adjusting unit 400 and/or the processor 210 .

畫面分析單元300可依據視場角調整模式的啟動與否，決定是否分析即時動態畫面M1的內容，且視場角調整單元400可依據視場角調整模式的啟動與否，決定是否依據使用者狀態U1改變顯示畫面F的視場角。 The picture analysis unit 300 can decide whether to analyze the content of the real-time dynamic picture M1 according to whether the viewing angle adjustment mode is activated or not, and the viewing angle adjustment unit 400 can determine whether to analyze the content of the real-time dynamic picture M1 according to the activation of the viewing angle adjustment mode. The state U1 changes the viewing angle of the display screen F.

舉例來說，畫面分析單元300可更用以：(1).在取得使用者與攝像器110之間的距離H1之前，判斷視場角調整模式是否處於一啟動狀態；當視場角調整模式處於啟動狀態時，方分析即時動態畫面M1的內容以取得距離。詳言之，當視場角調整模式啟動時，畫面分析單元300方分析即時動態畫面M1的內容。當視場角調整模式未啟動(如，處於關閉狀態)時，畫面分析單元300就不分析即時動態畫面M1的內容，如此可降低畫面分析單元300的工作負擔。相似地，當視場角調整模式啟動時，視場角調整單元400方依據使用者狀態U1改變顯示畫面F的視場角。當視場角調整模式未啟動時，視場角調整單元400不改變顯示畫面F的視場角，如此可降低視場角調整單元400的工作負擔。 For example, the image analysis unit 300 can be further used to: (1). Before obtaining the distance H1 between the user and the camera 110, determine whether the viewing angle adjustment mode is in an activated state; when the viewing angle adjustment mode When in the activated state, Fang analyzes the content of the real-time dynamic picture M1 to obtain the distance. In detail, when the viewing angle adjustment mode is activated, the image analysis unit 300 analyzes the content of the real-time dynamic image M1. When the viewing angle adjustment mode is not activated (for example, in an off state), the image analysis unit 300 does not analyze the content of the real-time dynamic image M1, which can reduce the workload of the image analysis unit 300 . Similarly, when the viewing angle adjustment mode is activated, the viewing angle adjusting unit 400 changes the viewing angle of the display frame F according to the user state U1 . When the viewing angle adjustment mode is not activated, the viewing angle adjusting unit 400 does not change the viewing angle of the display frame F, which can reduce the workload of the viewing angle adjusting unit 400 .

此外，視場角調整單元400可依據設定介面SE1所接收之視場角調整模式之關閉指令，關閉視場角調整模式。當視場角調整模式從啟動狀態變換至關閉狀態時，視場角調整單元400可將攝像器110之視場角參數設定ST回復(或，還原)至預設值。 In addition, the viewing angle adjustment unit 400 can close the viewing angle adjustment mode according to the closing command of the viewing angle adjustment mode received by the setting interface SE1. When the viewing angle adjustment mode is switched from the activated state to the closed state, the viewing angle adjustment unit 400 can restore (or restore) the viewing angle parameter setting ST of the camera 110 to the default value.

請參照第2圖，其繪示第1A圖之電子裝置10A的畫面控制方法的流程圖。 Please refer to FIG. 2 , which shows a flow chart of the screen control method of the electronic device 10A shown in FIG. 1A .

在步驟S110中，主機200A連接螢幕100A並提供顯示訊號D1由螢幕100A顯示顯示畫面F。 In step S110 , the host 200A is connected to the screen 100A and provides a display signal D1 to display a display frame F on the screen 100A.
