Description
本發明係關於一種投影裝置，特別係關於一種具有使用者介面之投影裝置。 The present invention relates to a projection apparatus, and more particularly to a projection apparatus having a user interface.
視訊投影系統被廣泛地用於許多種應用中。舉例來說，前側與背側影像投影系統被廣泛地應用於"大螢幕"家庭的娛樂系統，以提供相較於傳統陰極射線管在尺寸以及靈活度上較大之影像。此外，視訊投影系統可被用於戲院以播映電影或其他視訊節目，或是用於為相對較大量的觀眾展示影像。 Video projection systems are widely used in many applications. For example, front and back side image projection systems are widely used in "big screen" home entertainment systems to provide images that are larger in size and flexibility than conventional cathode ray tubes. In addition, video projection systems can be used in theaters to broadcast movies or other video programs, or to display images for a relatively large number of viewers.
視訊投影系統也被用於商業、教育、訓練和其他的領域，以顯示例如影像、圖片、表單、大綱等等之投影片，以供使用者檢視。在此一具體例中，視訊投影可以使得相對大量的人同時觀看一電腦桌面，以顯示該電腦的操作人員所進行之動作。因為視訊投影系統被廣泛的使用上述等環境下，故對現有的視訊投影系統的改良之需求係一直存在著。 Video projection systems are also used in business, education, training, and other fields to display slides such as images, pictures, forms, outlines, etc. for viewing by users. In this specific example, the video projection can cause a relatively large number of people to simultaneously view a computer desktop to display the actions performed by the operator of the computer. Since video projection systems are widely used in such environments, the need for improvements in existing video projection systems has always existed.
許多此種投影系統現在係被製造成一手提式投影機，以方便使用者提取並在需要時被架設。然而，在此種手提式投影機中，在遇到新的環境時，都需要重新進行對焦，否則無法呈現清晰之影像。 Many such projection systems are now manufactured as a hand-held projector for the user to extract and erect when needed. However, in such a portable projector, when a new environment is encountered, it is necessary to refocus, otherwise a clear image cannot be presented.
不幸地，大多數的人都覺得將投影機對焦是很困難的，特別是當所要投影的影像係為不具有顯著邊界的照片影像時。一些使用者必須非常地靠近該所投射的影像或是顯示一具有顯著線段或文字的影像，才能正確地將投影機對焦至適當的焦距上。Unfortunately, most people find it difficult to focus the projector, especially if the image to be projected is a photo image that does not have significant boundaries. Some users must be very close to the projected image or display an image with significant line segments or text in order to properly focus the projector to the appropriate focal length.

However, it is to be noted that many of the possible inventive concepts provided by the present invention can be implemented in various specific ranges. These specific examples are only intended to illustrate the apparatus and methods of use of the present invention, but are not intended to limit the scope of the invention.
第1圖為本發明所提供之投影裝置100之方塊圖。投影裝置100包括投影單元102、開關103、啟動模組104、開關模組106、自動偵測模組108、輸入裝置110、對焦裝置112以及記憶體114。投影單元102用以根據一焦距將儲存於記憶體114中之一對焦畫面P1以及一使用者對焦介面UI或者影像V1投影於一介面上。其中，當啟動模組104啟動一對焦模式時，開關103耦接至節點N1，並根據該焦距將一對焦畫面P1及/或一使用者對焦介面UI投影於一介面上。當啟動模組104未啟動對焦模式時，開關103耦接至節點N2，並根據調整後之焦距(或者未經調整之焦距)將影像V1投影於該介面上。值得注意的是，該介面可為任何被投影之物質，例如牆面、白板、白色布幕等等。另外，影像V1可為儲存於投影裝置100中另一記憶體(未圖示)中之影像檔案，或者自外部有線或者無線輸入端所接收之影像檔案，其中影像檔案之格式可為MPEG、JPG、AVI等等，本發明不加以限制。1 is a block diagram of a projection apparatus 100 provided by the present invention. The projection device 100 includes a projection unit 102, a switch 103, a startup module 104, a switch module 106, an automatic detection module 108, an input device 110, a focusing device 112, and a memory 114. The projection unit 102 is configured to project a focus picture P1 stored in the memory 114 and a user focus interface UI or image V1 on a interface according to a focal length. When the activation module 104 activates a focus mode, the switch 103 is coupled to the node N1, and a focus picture P1 and/or a user focus interface UI are projected on a interface according to the focal length. When the activation module 104 does not activate the focus mode, the switch 103 is coupled to the node N2, and the image V1 is projected onto the interface according to the adjusted focal length (or the unadjusted focal length). It is worth noting that the interface can be any material that is projected, such as a wall, a whiteboard, a white curtain, and the like. In addition, the image V1 may be an image file stored in another memory (not shown) of the projection device 100, or an image file received from an external wired or wireless input terminal, wherein the image file format may be MPEG or JPG. , AVI, etc., the invention is not limited.
啟動模組104根據一觸發訊號S1啟動對焦模式。在對焦模式下，啟動模組104致使投影單元102將對焦畫面P1投影於介面上，或者將使用者對焦介面UI覆蓋於對焦畫面P1上以投影於介面上。值得注意的是，觸發訊號S1之產生方式請參考下述開關模組106以及自動偵測模組108之說明，在此不再贅述。The startup module 104 activates the focus mode according to a trigger signal S1. In the focus mode, the activation module 104 causes the projection unit 102 to project the focus picture P1 onto the interface, or the user focus interface UI is overlaid on the focus picture P1 for projection on the interface. It should be noted that the manner of generating the trigger signal S1 is described in the following descriptions of the switch module 106 and the automatic detection module 108, and details are not described herein.
開關模組106根據使用者之操作產生觸發訊號S1。舉例而言，當使用者希望開啟對焦模式時，可藉由與投影裝置100匹配之遙控器、設置於投影裝置100上之按鍵或者觸碰面板，進行開啟對焦模式之操作。當開關模組106接收到使用者相應於開啟對焦模式之操作時，開關模組106產生觸發訊號S1。啟動模組104則根據相應於開啟對焦模式之觸發訊號S1啟動對焦模式。在另一實施例中，當使用者希望開啟對焦模式時，可藉由與投影裝置100匹配之遙控器、設置於投影裝置100上之按鍵或者觸碰面板，在投影裝置100內建之屏幕視控系統(On-Screen Display)中進行相應於開啟對焦模式之操作。The switch module 106 generates a trigger signal S1 according to the operation of the user. For example, when the user desires to turn on the focus mode, the operation of turning on the focus mode can be performed by a remote controller matched with the projection device 100, a button provided on the projection device 100, or a touch panel. When the switch module 106 receives the operation corresponding to the user to turn on the focus mode, the switch module 106 generates the trigger signal S1. The startup module 104 activates the focus mode according to the trigger signal S1 corresponding to the on-focus mode. In another embodiment, when the user desires to turn on the focus mode, the screen can be built in the projection device 100 by using a remote controller matched with the projection device 100, a button disposed on the projection device 100, or a touch panel. The operation of the on-focus mode is performed in the On-Screen Display.
自動偵測模組108包括一影像偵測器1081以及一環境偵測器1082。影像偵測器1081擷取投影於介面之畫面，並根據一演算法判斷投影於介面之畫面的畫質是否達到一既定清晰度。舉例而言，投影於介面之畫面可為投影裝置100之開機畫面。當演算法判斷投影於介面之畫面的畫質未達到既定清晰度時(即投影於介面上之對焦畫面P1係處於之不清楚的狀態時)，影像偵測器1081產生觸發訊號S1，並傳送至啟動模組104。啟動模組104則根據相應於開啟對焦模式之觸發訊號S1啟動對焦模式。另外，環境偵測器1082用以判斷投影裝置100之位置是否改變，並據以產生觸發訊號S1，且將觸發訊號S1傳送至啟動模組104。啟動模組104則根據相應於開啟對焦模式之觸發訊號S1啟動對焦模式。舉例而言，環境偵測器1082可為水平儀、陀螺儀、光源感測器或者各種感測器之組合，用以根據投影裝置100與介面之距離、投影裝置100之擺放角度及/或投影裝置100周圍之光源的改變與否，判斷投影裝置100之位置是否改變。當投影裝置100之位置改變時，環境偵測器1082產生觸發訊號S1。值得注意的是，判斷投影於介面之畫面的畫質是否達到既定清晰度之演算法，可為各種影像處理之演算，本發明不加以限制。The auto-detection module 108 includes an image detector 1081 and an environment detector 1082. The image detector 1081 captures the image projected on the interface, and determines whether the image quality projected on the interface reaches a predetermined definition according to an algorithm. For example, the screen projected on the interface may be a boot screen of the projection device 100. When the algorithm determines that the image quality projected on the interface does not reach the predetermined resolution (that is, when the focus picture P1 projected on the interface is in an unclear state), the image detector 1081 generates the trigger signal S1 and transmits To the startup module 104. The startup module 104 activates the focus mode according to the trigger signal S1 corresponding to the on-focus mode. In addition, the environment detector 1082 is configured to determine whether the position of the projection device 100 is changed, and accordingly generate the trigger signal S1, and transmit the trigger signal S1 to the startup module 104. The startup module 104 activates the focus mode according to the trigger signal S1 corresponding to the on-focus mode. For example, the environment detector 1082 can be a level, a gyroscope, a light source sensor, or a combination of various sensors for arranging the angle and/or projection of the projection device 100 according to the distance between the projection device 100 and the interface. Whether the position of the projection device 100 is changed or not is changed by the light source around the device 100. When the position of the projection device 100 changes, the environment detector 1082 generates a trigger signal S1. It is worth noting that the algorithm for judging whether the image quality projected on the interface reaches a predetermined resolution is a calculation for various image processing, and the present invention is not limited.
輸入裝置110接收使用者對應於焦距之操作，並產生相應之調整訊號S2，其中輸入裝置110可為一觸碰面板、一按鍵及/或一齒輪裝置，本發明不加以限制。當使用者觸碰或者轉動輸入裝置110時，輸入裝置110產生調整訊號S2，並致使投影單元102將使用者對焦介面UI投影於介面上。舉例而言，當使用者開始操作輸入裝置110以調整焦距時，投影單元102將使用者對焦介面UI投影於介面上，而對焦裝置112則根據調整訊號S2調整投影單元102之焦距。記憶體114用以儲存對焦畫面P1以及使用者對焦畫面UI。舉例而言，記憶體114可為用於存放多媒體(Multimedia)專用之快取記憶體(Flash)等，本發明不加以限制。The input device 110 receives the operation of the user corresponding to the focal length and generates a corresponding adjustment signal S2. The input device 110 can be a touch panel, a button and/or a gear device, which is not limited in the present invention. When the user touches or rotates the input device 110, the input device 110 generates the adjustment signal S2 and causes the projection unit 102 to project the user focus interface UI on the interface. For example, when the user starts to operate the input device 110 to adjust the focal length, the projection unit 102 projects the user focus interface UI on the interface, and the focusing device 112 adjusts the focal length of the projection unit 102 according to the adjustment signal S2. The memory 114 is used to store the focus picture P1 and the user focus picture UI. For example, the memory 114 may be a multimedia memory (Flash) or the like for storing multimedia, and the present invention is not limited thereto.
在另一實施例中，當投影裝置100處於較暗之環境下，一般的投影裝置100容易投影出過曝的畫面，造成對焦畫面P1或者影像V1模糊，導致對焦之效果或者觀看之影像不清楚。因此，投影單元102可藉由環境偵測器1082中之光源感測器(未圖示)及/或影像偵測器1081，對投影裝置100周圍之光源進行偵測。環境偵測器1082根據投影裝置100周圍之光源，致使投影單元102對對焦畫面P1(或者影像V1)之灰階值以及亮度進行調整，使得對焦畫面P1(或者影像V1)更加清楚。舉例而言，當投影裝置100處於較暗之環境下時，投影單元102可根據環境偵測器1082中之光源感測器(未圖示)或者影像偵測器1081之偵測結果產生的一偵測訊號S3，自動將對焦畫面的灰階值(Gray level)或是將投影裝置100中的亮度(Brightness)的設定值降低，以避免投影裝置100在較暗的環境中之投影過度曝光而影響對焦動作。值得注意的是，投影單元102亦可根據其他設置於投影裝置100中之感測器對周圍之光源之偵測結果，致使投影單元102對對焦畫面P1(或者影像V1)之灰階值以及亮度進行調整，使得對焦畫面P1(或者影像V1)更加清楚。In another embodiment, when the projection device 100 is in a dark environment, the general projection device 100 can easily project an overexposed image, causing the focus picture P1 or the image V1 to be blurred, resulting in the effect of focusing or the image being viewed is unclear. . Therefore, the projection unit 102 can detect the light source around the projection device 100 by the light source sensor (not shown) and/or the image detector 1081 in the environment detector 1082. The environment detector 1082 causes the projection unit 102 to adjust the grayscale value and the brightness of the focus picture P1 (or the image V1) according to the light source around the projection device 100, so that the focus picture P1 (or the image V1) is more clear. For example, when the projection device 100 is in a dark environment, the projection unit 102 can generate one according to the detection result of the light source sensor (not shown) or the image detector 1081 in the environment detector 1082. The detection signal S3 automatically reduces the gray level value of the focus picture or the brightness value of the projection device 100 to avoid overexposure of the projection device 100 in a dark environment. Affect the focus action. It should be noted that the projection unit 102 can also cause the projection unit 102 to determine the grayscale value and brightness of the focus picture P1 (or the image V1) according to the detection result of the surrounding light source of the sensor disposed in the projection device 100. Make adjustments to make the focus picture P1 (or image V1) clearer.
第2A以及2B圖為本發明所提供之對焦畫面P1之示意圖。對焦畫面P1具有複數線條以及複數字元，用以判斷投影單元102目前之焦距是否在投影單元102以及介面之焦點上，即投影單元102目前之焦距是否可將對焦畫面P1清楚的呈現於介面上。由於使用者將會根據觀看畫面來進行對焦程度的調整，對焦畫面P1的選取也將間接影響對焦結果。因此，選擇最佳的對焦畫面是達到調整最佳對焦結果的關鍵之一。舉例而言，在投影畫面中，使用者最容易觀察到的是畫面中的顏色與輪廓，對焦程度的好壞會直接決定輪廓呈現的好壞。因此，對焦畫面P1需具有大部分輪廓畫面(edge point)，或是文字畫面，這些畫面可以直接讓使用者斷定輪廓是否有分叉，來決定是否進行對焦設定的修正。值得注意的是，第2A以及2B圖為本發明之兩種實施例，但本發明不限於此。2A and 2B are schematic views of the focus picture P1 provided by the present invention. The focus picture P1 has a plurality of lines and a complex digital element for determining whether the current focal length of the projection unit 102 is at the focus of the projection unit 102 and the interface, that is, whether the current focal length of the projection unit 102 can clearly display the focus picture P1 on the interface. . Since the user will adjust the focus level according to the viewing screen, the selection of the focus screen P1 will indirectly affect the focusing result. Therefore, choosing the best focus screen is one of the keys to adjusting the best focus results. For example, in the projected picture, the color and outline of the picture are the easiest for the user to observe. The degree of focus will directly determine the quality of the outline. Therefore, the focus picture P1 needs to have most of the edge points or text pictures, and these pictures can directly determine whether the outline has a bifurcation to determine whether to perform the correction of the focus setting. It is to be noted that the 2A and 2B drawings are two embodiments of the present invention, but the present invention is not limited thereto.
第3圖為本發明所提供之使用者對焦介面UI之示意圖。使用者對焦介面UI具有複數焦距刻度以及隨著目前焦距調整之一指標，其中該指標用以表示投影單元102目前之焦距。在現行的焦距調整方式中，使用者只能沒有準則地旋轉對焦調整紐，進行順時鐘或者逆時鐘之調整，直到畫面覺得對焦成功而停止。有鑑於此，本發明在使用者調整的過程中，提供使用者使用者對焦介面UI，以在投影畫面上顯示出調整刻度的畫面，進而輔助使用者進行對焦的動作。使用者對焦介面UI包含焦距刻度、數字、已旋轉幅度的輔助提示及/或顯示調整狀態的指針，以幫助使用者有可以記憶的數值以及角度，並且在使用者調整焦距時，相應地調整與變動。FIG. 3 is a schematic diagram of a user focus interface UI provided by the present invention. The user focus interface UI has a complex focus scale and an indicator of the current focus adjustment, wherein the indicator is used to indicate the current focal length of the projection unit 102. In the current focus adjustment method, the user can only rotate the focus adjustment button without a criterion, and perform clockwise or inverse clock adjustment until the screen feels that the focus is successful and stops. In view of this, in the process of user adjustment, the user provides a user interface focusing interface UI to display a screen for adjusting the scale on the projection screen, thereby assisting the user in performing the focusing operation. The user focus interface UI includes a focal length scale, a number, an auxiliary prompt for the rotated range, and/or a pointer for displaying the adjustment state to help the user have a value and an angle that can be memorized, and when the user adjusts the focal length, adjusts accordingly. change.
第4圖為本發明所提供之一對焦方法的流程圖。流程開始於步驟S400。Figure 4 is a flow chart of one of the focusing methods provided by the present invention. The flow begins in step S400.
在步驟S400中，使用者啟動投影裝置100。In step S400, the user activates the projection device 100.
接著，在步驟S402中，啟動模組104判斷是否接收到一觸發訊號S1。其中，開關模組106根據使用者之操作產生觸發訊號S1，並將觸發訊號S1傳送至啟動模組104。在另一實施例中，影像偵測器1081擷取投影於介面之畫面，並根據一演算法判斷投影於介面之畫面的畫質是否達到一既定清晰度，以產生觸發訊號S1。在另一實施例中，環境偵測器1082判斷投影裝置100之位置是否改變，並當投影裝置100之位置改變時產生觸發訊號S1。其中，判斷投影裝置100之位置是否改變的步驟更包括根據投影裝置100與介面之距離、投影裝置100之擺放角度及/或投影裝置100周圍之光源，判斷投影裝置100之位置是否改變。當啟動模組104接收到一觸發訊號S1時，流程進行至步驟S404。否則，流程進行至步驟S410。 Next, in step S402, the startup module 104 determines whether a trigger signal S1 is received. The switch module 106 generates the trigger signal S1 according to the operation of the user, and transmits the trigger signal S1 to the startup module 104. In another embodiment, the image detector 1081 captures the image projected on the interface, and determines whether the image quality of the image projected on the interface reaches a predetermined resolution according to an algorithm to generate the trigger signal S1. In another embodiment, the environment detector 1082 determines whether the position of the projection device 100 has changed, and generates a trigger signal S1 when the position of the projection device 100 changes. The step of determining whether the position of the projection device 100 is changed further includes determining whether the position of the projection device 100 is changed according to the distance between the projection device 100 and the interface, the placement angle of the projection device 100, and/or the light source around the projection device 100. When the startup module 104 receives a trigger signal S1, the flow proceeds to step S404. Otherwise, the flow proceeds to step S410.
在步驟S404中，投影單元102根據觸發訊號S1，致使投影單元102根據一焦距，將一對焦畫面P1投影於介面上。 In step S404, the projection unit 102 causes the projection unit 102 to project a focus picture P1 on the interface according to a focal length according to the trigger signal S1.
接著，在步驟S406中，輸入裝置110判斷是否接收到使用者對應於調整焦距之操作，並產生相應之調整訊號S2。舉例而言，當使用者觸碰或者轉動輸入裝置110時，輸入裝置110產生調整訊號S2。當輸入裝置110判斷接收到使用者對應於調整焦距之操作，並產生調整訊號S2時，流程進行至步驟S408。否則，流程進行至步驟S410。 Next, in step S406, the input device 110 determines whether an operation corresponding to the adjustment of the focus is received by the user, and generates a corresponding adjustment signal S2. For example, when the user touches or rotates the input device 110, the input device 110 generates an adjustment signal S2. When the input device 110 determines that the operation corresponding to the adjusted focus is received by the user and generates the adjustment signal S2, the flow proceeds to step S408. Otherwise, the flow proceeds to step S410.
在步驟S408中，對焦裝置112根據調整訊號S2，致使投影單元102根據焦距，將一使用者對焦介面UI覆蓋於對焦畫面P1投影於介面上，並根據調整訊號S2調整投影單元102之焦距。舉例而言，當使用者觸碰或者轉動輸入裝置110時，輸入裝置110產生調整訊號S2，同時投影單元102將使用者對焦介面UI投影於介面上。值得注意的是，在使用者調整的過程中，使用者對焦介面UI在投影畫面上顯示出調整刻度的畫面，進而輔助使用者進行對焦的動作。使用者對焦介面UI包含焦距刻度、數字、已旋轉幅度的輔助提示及/或顯示調整狀態的指針，以幫助使用者有可以記憶的數值以及角度，並且在使用者調整焦距時，相應地調整與變動。接著流程進行至步驟S410。 In step S408, the focusing device 112 causes the projection unit 102 to project a user focus interface UI on the focusing screen P1 according to the focal length, and adjust the focal length of the projection unit 102 according to the adjustment signal S2. For example, when the user touches or rotates the input device 110, the input device 110 generates the adjustment signal S2, and the projection unit 102 projects the user focus interface UI on the interface. It is worth noting that during the user adjustment process, the user focus interface UI displays a screen for adjusting the scale on the projection screen, thereby assisting the user in performing the focusing operation. The user focus interface UI includes a focal length scale, a number, an auxiliary prompt for the rotated range, and/or a pointer for displaying the adjustment state to help the user have a value and an angle that can be memorized, and when the user adjusts the focal length, adjusts accordingly. change. The flow then proceeds to step S410.
在步驟S410中，投影單元102根據目前之焦距，將影像V1投影於介面上。 In step S410, the projection unit 102 projects the image V1 onto the interface according to the current focal length.
在步驟S412中，投影裝置100判斷使用者是否結束投影。當使用者結束投影時，流程結束。否則，流程回到步驟S402。 In step S412, the projection apparatus 100 determines whether the user has finished projecting. When the user ends the projection, the flow ends. Otherwise, the flow returns to step S402.
