Description
本發明係有關切換顯示模式的系統及其方法，特別是關於一種對電子產品切換顯示模式的系統及其方法。The present invention relates to a system and method for switching display modes, and more particularly to a system and method for switching display modes to electronic products.
一般具有顯示功能的電子產品可呈現文件或影片供使用者觀看，且這些電子產品通常為了系統效能考量，會設計成一段時間內若未接收到輸入訊號，例如移動滑鼠或鍵盤輸入，便自動控制螢幕變暗以進入省電模式，甚至自動關機。Generally, electronic products with display functions can present files or videos for users to watch, and these electronic products are usually designed for system performance considerations, and are designed to automatically input an input signal for a period of time, such as moving a mouse or keyboard input. Control the screen to darken to enter the power saving mode, or even automatically shut down.
然而，使用者雖然沒有操作電子產品，但仍可能正在使用它，例如正在觀看文件，因而若僅是偵測是否接收到輸入訊號來判斷產品是否正被使用，常常會造成顯示模式切換上的誤判而使得使用不便。However, although the user does not operate the electronic product, it may still be using it, for example, watching a file, so if it is only detecting whether an input signal is received to determine whether the product is being used, the display mode switching is often misjudged. It makes use inconvenient.
鑑於上述，因此亟需提出一種新穎的切換顯示模式的系統及其方法，以讓使用者可以在電子產品上長時間閱讀而不被中斷。In view of the above, it is therefore desirable to propose a novel system and method for switching display modes so that users can read on electronic products for a long time without interruption.
本發明實施例的目的之一在於提出一種切換顯示模式的系統及其方法，其能讓使用者在電子顯示產品上長時間閱讀而不被中斷，並能正確地切換顯示模式，以提高操作效能。One of the objectives of the embodiments of the present invention is to provide a system for switching display modes and a method thereof, which enable a user to read on an electronic display product for a long time without interruption, and can correctly switch the display mode to improve operational efficiency. .
本發明係揭示一種切換顯示模式的系統，包括一顯示單元、一注視偵測單元及一處理單元。注視偵測單元係用來偵測顯示單元前方的影像。處理單元係耦接於顯示單元及注視偵測單元之間，根據注視偵測單元所偵測的影像來控制顯示單元。其中，當注視偵測單元偵測到一人臉影像，處理單元便控制顯示單元進入一工作模式。The invention discloses a system for switching display modes, comprising a display unit, a gaze detection unit and a processing unit. The gaze detection unit is used to detect an image in front of the display unit. The processing unit is coupled between the display unit and the gaze detecting unit, and controls the display unit according to the image detected by the gaze detecting unit. Wherein, when the gaze detecting unit detects a face image, the processing unit controls the display unit to enter a working mode.
本發明又揭示一種切換顯示模式的方法，係適用於一包括一顯示單元的電子裝置，所述之方法包括以下步驟：偵測顯示單元前方的影像，並判斷所偵測的影像是否包含一人臉影像；若所偵測的影像包括人臉影像，則控制顯示單元進入一工作模式。The invention further discloses a method for switching a display mode, which is applicable to an electronic device including a display unit, the method comprising the steps of: detecting an image in front of the display unit, and determining whether the detected image includes a face. Image; if the detected image includes a face image, the display unit is controlled to enter a working mode.
請參考第一圖，係顯示本發明實施例之切換顯示模式的系統之方塊圖。如圖所示，切換顯示模式的系統可應用於一電子裝置1，其主要包括一顯示單元11、一注視偵測單元13以及一處理單元15。具體來說，電子裝置1可以為桌上型電腦、筆記型電腦、手攜式PC、個人數位助理、或手機，但不以此為限。當然，電子裝置1中更包括其他必要元件，其為本領域之習知技藝者所能輕易思及，為了不模糊本發明之主要技術概念，在此便不予以贅述。Please refer to the first figure, which is a block diagram showing a system for switching display modes according to an embodiment of the present invention. As shown in the figure, the system for switching the display mode can be applied to an electronic device 1, which mainly includes a display unit 11, a gaze detecting unit 13, and a processing unit 15. Specifically, the electronic device 1 may be a desktop computer, a notebook computer, a hand-held PC, a personal digital assistant, or a mobile phone, but is not limited thereto. Of course, the electronic device 1 further includes other necessary components, which can be easily considered by those skilled in the art, and will not be further described herein in order not to obscure the main technical concept of the present invention.
注視偵測單元13係用來偵測顯示單元11前方的影像。具體來說，注視偵測單元13可以是攝影機或照相機，用來擷取朝向顯示單元11的畫面。處理單元15係耦接於顯示單元11及注視偵測單元13之間，用來根據注視偵測單元13所擷取到的影像來控制顯示單元11。具體來說，處理單元15包括一數位信號處理器(DSP)、一微控制器、一專用積體電路(ASIC)、或一微處理器。The gaze detecting unit 13 is for detecting an image in front of the display unit 11. Specifically, the gaze detecting unit 13 may be a camera or a camera for capturing a picture toward the display unit 11. The processing unit 15 is coupled between the display unit 11 and the gaze detecting unit 13 for controlling the display unit 11 according to the image captured by the gaze detecting unit 13. In particular, processing unit 15 includes a digital signal processor (DSP), a microcontroller, a dedicated integrated circuit (ASIC), or a microprocessor.
在實作上，若注視偵測單元13識別顯示單元11前有一人臉影像，就表示目前可能有使用者正在觀看顯示單元11所呈現的內容，於是處理單元15便控制顯示單元11進入一工作模式，讓使用者能正常觀看其中內容。反之，若注視偵測單元13於一預定時間內都未偵測到顯示單元11前有任何人臉影像，就表示使用者目前可能沒有操作此電子裝置1，則處理單元15便控制顯示單元11進入一省電模式，例如調降螢幕亮度或甚至關閉螢幕，以避免功率消耗。In practice, if the gaze detecting unit 13 recognizes that there is a face image in front of the display unit 11, it indicates that there is currently a user who is watching the content presented by the display unit 11, and the processing unit 15 controls the display unit 11 to enter a job. Mode, allowing users to view the content properly. On the other hand, if the gaze detecting unit 13 does not detect any facial image before the display unit 11 for a predetermined time, it means that the user may not operate the electronic device 1 at present, the processing unit 15 controls the display unit 11 Enter a power saving mode, such as reducing the brightness of the screen or even turning off the screen to avoid power consumption.
考量使用者即使面對螢幕，眼睛也有可能在看其他地方的情況，因此於另一實施例中，注視偵測單元13亦可以是一眼球追蹤裝置(eye tracking device)，用來追蹤顯示單元11前的一觀賞者之眼睛活動(eye movement)。當眼球追蹤裝置偵測到觀賞者朝向顯示單元11觀看時，處理單元15便控制顯示單元11進入工作模式，而若眼球追蹤裝置於預定時間內未偵測到觀賞者朝向顯示單元11觀看，則處理單元15便控制顯示單元11進入省電模式。透過追蹤人眼觀看方向，便可更精確地判斷來切換顯示模式。Considering that the user may be looking at other places even if facing the screen, in another embodiment, the gaze detecting unit 13 may also be an eye tracking device for tracking the display unit 11 The eye movement of a former viewer. When the eyeball tracking device detects that the viewer is looking toward the display unit 11, the processing unit 15 controls the display unit 11 to enter the working mode, and if the eyeball tracking device does not detect that the viewer is looking toward the display unit 11 within a predetermined time, then The processing unit 15 controls the display unit 11 to enter the power saving mode. By tracking the direction of the human eye, the display mode can be switched more accurately.
第二圖顯示本發明實施例之切換顯示模式的方法之流程圖，其可適用於第一圖所示的電子裝置1。The second figure shows a flow chart of a method for switching display modes according to an embodiment of the present invention, which is applicable to the electronic device 1 shown in the first figure.
首先，注視偵測單元13會偵測面對顯示單元11的影像(步驟S201)，並隨時判斷目前偵測的影像是否包括人臉影像(步驟S203)。當然，亦可藉由眼球追蹤裝置來判斷使用者的觀看方向。First, the gaze detecting unit 13 detects the image facing the display unit 11 (step S201), and determines whether the currently detected image includes a face image at any time (step S203). Of course, the viewing direction of the user can also be judged by the eyeball tracking device.
若注視偵測單元13於預定時間內都未偵測到顯示單元11前有任何人臉影像，就表示使用者目前可能沒有操作此電子裝置1，則處理單元15便控制顯示單元11進入省電模式(步驟S205)。若注視偵測單元13識別顯示單元11前有人臉影像，則進一步判斷使用者的觀看方向是否朝向顯示單元11(步驟S207)。If the gaze detecting unit 13 does not detect any facial image in front of the display unit 11 within a predetermined time, it means that the user may not operate the electronic device 1 at present, the processing unit 15 controls the display unit 11 to enter the power saving. Mode (step S205). If the gaze detecting unit 13 recognizes the face image before the display unit 11, it is further determined whether the viewing direction of the user is toward the display unit 11 (step S207).
若判斷使用者的眼睛朝向顯示單元11，就表示使用者正在觀看顯示單元11所呈現的內容，於是處理單元15便控制顯示單元11進入工作模式(步驟S209)；否則便控制顯示單元11進入省電模式(步驟S205)。If it is determined that the user's eyes are facing the display unit 11, it means that the user is watching the content presented by the display unit 11, and then the processing unit 15 controls the display unit 11 to enter the working mode (step S209); otherwise, the display unit 11 is controlled to enter the province. Electrical mode (step S205).
根據上述實施例，本發明所提出的切換顯示模式的系統及方法，係透過識別螢幕前方是否有人臉來判斷目前是否操作電子裝置，如此便能讓使用者在電子顯示產品上長時間閱讀而不被中斷，並能正確地切換顯示模式，以提高操作效能。According to the above embodiment, the system and method for switching the display mode proposed by the present invention determines whether the electronic device is currently operated by recognizing whether there is a human face in front of the screen, so that the user can read the electronic display product for a long time without Interrupted and correctly switched display mode to improve operational efficiency.
