Description
本發明主要係關於一種影像顯示裝置，特別係有關於一種顯示立體影像之影像顯示裝置。The present invention relates generally to an image display device, and more particularly to an image display device for displaying a stereoscopic image.
由於人體左眼所補捉到的影像與右眼所補捉到的影像是不一樣的，且左眼與右眼所看到的視差影像是相互獨立的，因此左眼與右眼所看到影像的不同可辨認目標物的距離，而產生立體影像的效果。目前為了使影像產生立體的效果，必須分別對左右眼提供二個不同的視角之影像，以產生具視差之影像。Since the image captured by the left eye of the human body is different from the image captured by the right eye, and the parallax images seen by the left eye and the right eye are independent of each other, the left eye and the right eye see each other. Different images can identify the distance of the target and produce a stereoscopic image. At present, in order to make a stereoscopic effect of an image, it is necessary to separately provide images of two different viewing angles to the left and right eyes to generate an image with parallax.
現存的立體影像顯示系統，為使左右眼分別觀看到對應視角的影像，可藉由立體眼鏡觀看螢幕上所顯示影像而達到立體之效果，其中快門眼鏡是最廣為應用的技術，藉由快門眼鏡打開左眼，觀看者可以看到螢幕上左眼的立體影像，同時，由於右眼是關閉的，遮蔽了右眼所能看到任何影像。藉由左眼/右眼立體影像之適當的更新顯示速率及快門眼鏡左右眼的開閉操作，使得左眼只能看到左眼的立體影像而右眼也只能看到右眼的立體影像，並由於人類視覺暫留以及前述視差的特性，故能達成立體影像效果。The existing stereoscopic image display system can realize the stereoscopic effect by viewing the images displayed on the screen by stereo glasses in order to make the left and right eyes respectively view the images of the corresponding viewing angles, wherein the shutter glasses are the most widely used technology, with the shutter The glasses open the left eye, and the viewer can see the stereoscopic image of the left eye on the screen. At the same time, since the right eye is closed, any image can be seen by obscuring the right eye. By appropriately updating the display rate of the left-eye/right-eye stereoscopic image and the opening and closing operation of the left and right eyes of the shutter glasses, the left eye can only see the stereoscopic image of the left eye, and the right eye can only see the stereoscopic image of the right eye. And because of the persistence of human vision and the characteristics of the aforementioned parallax, a stereoscopic image effect can be achieved.
為了使快門眼鏡正確切換左右眼開關，需要利用一個同步的信號以控制快門眼鏡之切換。然而，若是同步信號發生延遲或錯誤，則會造成無法正常的顯示出立體影像。因此，需要一種判斷影像方法以切換左右眼所觀看之影像。In order for the shutter glasses to properly switch the left and right eye switches, it is necessary to utilize a synchronized signal to control the switching of the shutter glasses. However, if the sync signal is delayed or incorrect, the stereo image will not be displayed properly. Therefore, there is a need for a method of determining an image to switch the images viewed by the left and right eyes.

The description of the basic concepts of the invention is not intended to be limiting. The scope of the invention is best defined in the scope of the appended claims.
第1圖係顯示根據本發明一實施例所述之立體影像顯示裝置100之方塊圖。根據本發明一實施例所述之立體影像顯示裝置100，適用於一視覺輔助裝置130，包括一顯示裝置110以及一處理裝置120。在本發明一些實施例中，視覺輔助裝置為一立體顯示眼鏡(例如，快門式3D眼鏡(shutter glasses))，具有一左眼視區132以及一右眼視區134。顯示裝置110用以顯示影像資料，處理裝置120用以進行影像資料之判斷及運算，影像資料可為外部輸入之影像資料或是儲存於立體影像顯示裝置100中之影像資料，其中影像資料包括一或多個子畫面。1 is a block diagram showing a stereoscopic image display device 100 according to an embodiment of the invention. The stereoscopic image display device 100 according to an embodiment of the invention is applicable to a visual aid device 130, including a display device 110 and a processing device 120. In some embodiments of the invention, the visual aid is a stereoscopic display eyewear (eg, shuttered 3D glasses) having a left eye viewing zone 132 and a right eye viewing zone 134. The display device 110 is configured to display image data, and the processing device 120 is configured to perform image data determination and calculation. The image data may be externally input image data or image data stored in the stereoscopic image display device 100, wherein the image data includes a Or multiple sub-pictures.
第2A圖係顯示本發明實施例之一第一子畫面200以及第2B圖係顯示影像資料之一第二子畫面210。第一子畫面200以及第二子畫面210於連續播放下在視覺上構成一立體影像。在本發明一些實施例中，第一子畫面200包括一靜態影像202(或一背景)以及一影像物件204，第二子畫面210包括一靜態影像212(或一背景)以及一影像物件214，其中，靜態影像202以及靜態影像212係對應於相同之靜態影像或背景，影像物件204以及影像物件214係對應於相同的影像物件，但皆因為具有不同之視角而有些許的差異。舉例來說，第2A圖中靜態影像202以及影像物件204對應於左眼之視角，第2B圖中而靜態影像212以及影像物件214對應於右眼之視角，並於不同時間交錯顯示以產生立體影像，其中於顯示裝置上右眼視角之影像之位置比起左眼視角之影像之位置較為右側。FIG. 2A shows a second sub-screen 210 of one of the first sub-pictures 200 and 2B of the embodiment of the present invention. The first sub-picture 200 and the second sub-picture 210 visually constitute a stereoscopic image under continuous playback. In some embodiments of the present invention, the first sub-picture 200 includes a still image 202 (or a background) and an image object 204. The second sub-picture 210 includes a still image 212 (or a background) and an image object 214. The static image 202 and the still image 212 correspond to the same still image or background, and the image object 204 and the image object 214 correspond to the same image object, but all have slight differences because of different viewing angles. For example, in FIG. 2A, the still image 202 and the image object 204 correspond to the angle of view of the left eye, and in FIG. 2B, the still image 212 and the image object 214 correspond to the angle of view of the right eye, and are alternately displayed at different times to generate a stereoscopic image. The image in which the position of the image of the right-eye view on the display device is closer to the right than the position of the image of the left-eye view.
為了在視覺上構成立體影像，第一子畫面200以及第二子畫面210之影像需有所偏移。因此，處理裝置120可判斷第一子畫面200以及第二子畫面210之差異(例如，右眼之畫面在顯示裝置上較左眼畫面偏右)，以決定第一子畫面200以及第二子畫面210所分別對應之類別，根據第一子畫面200以及第二子畫面210所分別對應之類別輸出一控制信號CRTL以控制視覺輔助裝置130，其控制信號之傳送方式可經由有線或無線之方式傳送置視覺輔助裝置130，以控制左眼視區132以及右眼視區134之透光性，進而使視覺產生立體影像。在本發明另一實施例中，更可利用DLP Link技術，將控制信號安插於二子畫面之間以控制視覺輔助裝置。In order to visually form a stereoscopic image, the images of the first sub-picture 200 and the second sub-picture 210 need to be offset. Therefore, the processing device 120 can determine the difference between the first sub-picture 200 and the second sub-picture 210 (eg, the picture of the right eye is on the display device to the right of the left-eye picture) to determine the first sub-picture 200 and the second sub-picture. The types corresponding to the screens 210 respectively output a control signal CRTL according to the categories corresponding to the first sub-screen 200 and the second sub-screen 210 to control the visual aid device 130, and the control signal can be transmitted via wired or wireless means. The visual aid device 130 is coupled to control the light transmission of the left eye viewing zone 132 and the right eye viewing zone 134 to visually produce a stereoscopic image. In another embodiment of the present invention, the DLP Link technology can be used to insert a control signal between the two sub-pictures to control the visual aid.
本發明一實施例中，處理裝置120可利用一演算法根據第一子畫面200以及第二子畫面210相對應之一顯示物件的位移以判斷第一子畫面200以及第二子畫面210之類別，當第二子畫面210之顯示物件比起第一子畫面200之顯示物件較為偏右，則判斷第一子畫面200為左眼視角之影像，第二子畫面210為右眼視角之影像，並根據其影像類別輸出一控制信號CRTL至視覺輔助裝置130，使視覺輔助裝置130依照影像之類別切換左右眼視區之透光性，以使視覺產生立體影像。其中顯示物件可為第一子畫面200以及第二子畫面210相對應的任意區塊(例如，靜態影像202、212或是影像物件204、214)，應可了解區塊並非限定於此，亦可選擇畫面中任何一部分作為區塊以供判斷。在本發明另一實施例，影像資料可具有一影像資訊，該影像資訊具有顯示物件於第一子畫面200以及於第二子畫面210之顯示位置之變化之指示(例如，靜態影像202到212之位置變化，影像物件204到214之位置變化)，處理裝置120可根據該影像資訊決定第一子畫面200以及第二子畫面210所分別對應之類別。在本發明另一實施例，影像資料更可為MPEG-4格式，其中具有移動向量(montion vector)之影像資訊，故處理器120可根據移動向量決定第一子畫面200以及第二子畫面210所分別對應之類別。In an embodiment of the present invention, the processing device 120 may use an algorithm to display the displacement of the object according to the corresponding one of the first sub-picture 200 and the second sub-picture 210 to determine the categories of the first sub-picture 200 and the second sub-picture 210. When the display object of the second sub-picture 210 is relatively farther than the display object of the first sub-picture 200, it is determined that the first sub-picture 200 is an image of a left-eye view, and the second sub-picture 210 is an image of a right-eye view.

The display object may be any block corresponding to the first sub-picture 200 and the second sub-picture 210 (for example, the static image 202, 212 or the image objects 204, 214), and it should be understood that the block is not limited thereto, and Any part of the picture can be selected as a block for judgment. In another embodiment of the present invention, the image data may have an image information having an indication of a change in the display position of the first sub-picture 200 and the second sub-picture 210 (eg, still images 202 to 212). The position of the image objects 204 to 214 changes, and the processing device 120 can determine the categories corresponding to the first sub-picture 200 and the second sub-picture 210 according to the image information. In another embodiment of the present invention, the image data may be in the MPEG-4 format, and the image information of the montion vector is included, so the processor 120 may determine the first sub-picture 200 and the second sub-picture 210 according to the motion vector. The category corresponding to each.
在本發明一些實施例中，其中第一子畫面200係對應於左眼影像，第二子畫面210係對應於右眼影像，當顯示第一子畫面200時，控制信號使左眼視區132之透光性大於右眼視區134，當顯示第二子畫面時210，控制信號使左眼視區132之透光性小於右眼視區134，藉由交錯變換左右眼視區之透光性，以使視覺產生立體影像。In some embodiments of the present invention, the first sub-picture 200 corresponds to the left-eye image, and the second sub-picture 210 corresponds to the right-eye image. When the first sub-picture 200 is displayed, the control signal causes the left-eye view area 132. The light transmittance is greater than the right eye viewing area 134. When the second sub-picture 210 is displayed, the control signal makes the left-eye viewing area 132 less transmissive than the right-eye viewing area 134, and the light transmission of the left and right eye viewing areas is interleaved. Sexuality to create a stereoscopic image of the vision.
第3圖係顯示根據本發明一實施例所述之立體影像顯示方法之操作流程圖。於步驟S302中，接收一影像資料，其中影像資料包括一第一子畫面200以及一第二子畫面210，且第一子畫面200以及第二子畫面210在視覺上構成一立體影像。FIG. 3 is a flow chart showing the operation of a stereoscopic image display method according to an embodiment of the invention. In step S302, an image data is received, wherein the image data includes a first sub-picture 200 and a second sub-picture 210, and the first sub-picture 200 and the second sub-picture 210 visually form a stereoscopic image.
於步驟S304中，擷取第一子畫面200以及第二子畫面210。在某些實施例中，更可擷取影像資料中之一影像資訊，該影像資訊指示顯示物件於第一子畫面200以及於第二子畫面210之顯示位置之變化。In step S304, the first sub-screen 200 and the second sub-screen 210 are captured. In some embodiments, one of the image data in the image data is captured, and the image information indicates a change in the display position of the first sub-picture 200 and the second sub-picture 210.
於步驟S306中，判斷第一子畫面200以及第二子畫面210之一差異。在一些實施例中，更可利用影像資訊決定第一子畫面200以及第二子畫面210所分別對應之類別。In step S306, a difference between the first sub-screen 200 and the second sub-screen 210 is determined. In some embodiments, the image information is used to determine the categories corresponding to the first sub-picture 200 and the second sub-picture 210, respectively.
於步驟S308中，根據差異決定第一子畫面200以及第二子畫面210分別對應之類別。在本發明一些實施例中，一顯示物件於第一子畫面200之顯示位置以及於第二子畫面210之顯示位置決定第一子畫面200以及第二子畫面210所分別對應之類別，類別可包括一左眼影像以及一右眼影像，其中顯示物件可為一影像物件(例如，影像物件204或214)或一靜態影像(例如，靜態影像202、212)之一或其組合。在一些實施例中，可藉由影像資訊決定第一子畫面以及第二子畫面所分別對應之類別，例如，當影像資料為MPEG-4時，可利用移動向量作為該影像資訊決定第一子畫面以及第二子畫面所分別對應之類別。In step S308, the categories corresponding to the first sub-screen 200 and the second sub-screen 210 are determined according to the difference. In some embodiments of the present invention, a display object at a display position of the first sub-screen 200 and a display position of the second sub-screen 210 determine a category corresponding to the first sub-screen 200 and the second sub-screen 210, respectively. The image includes a left eye image and a right eye image, wherein the display object can be one of an image object (eg, image object 204 or 214) or a static image (eg, still image 202, 212) or a combination thereof. In some embodiments, the information corresponding to the first sub-picture and the second sub-picture may be determined by the image information. For example, when the image data is MPEG-4, the motion vector may be used as the image information to determine the first sub-picture. The category corresponding to the screen and the second sub-screen.
於步驟S310中，根據第一子畫面200以及第二子畫面210所分別對應之類別輸出一控制信號CRTL以控制一視覺輔助裝置130。在一些實施例中，視覺輔助裝置130為具有一左眼視區132以及一右眼視區134之立體顯示眼鏡，而控制信號係控制左眼視區132以及右眼視區134之透光性。其中第一子畫面200係對應於左眼影像，第二子畫面210係對應於右眼影像，當顯示第一子畫面200時，控制信號使左眼視區132之透光性大於右眼視區134，當顯示第二子畫面210時，控制信號使左眼視區132之透光性小於右眼視區134，藉由交錯變換左右眼視區之透光性，故可使視覺產生立體影像。應可了解，上述方法流程可進一步對其中之步驟刪減、加入、合併，仍可完成本發明，例如，直接利用影像資訊作為分類以省略分類之步驟。In step S310, a control signal CRTL is output according to the categories corresponding to the first sub-screen 200 and the second sub-screen 210 to control a visual aid 130. In some embodiments, the visual aid 130 is a stereoscopic display glasses having a left eye viewing zone 132 and a right eye viewing zone 134, and the control signal controls the light transmission of the left eye viewing zone 132 and the right eye viewing zone 134. . The first sub-picture 200 corresponds to the left-eye image, and the second sub-picture 210 corresponds to the right-eye image. When the first sub-picture 200 is displayed, the control signal makes the left-eye view area 132 more transmissive than the right-eye view. In the area 134, when the second sub-picture 210 is displayed, the control signal makes the left-eye view area 132 less transmissive than the right-eye view area 134, and the optical transmittance of the left and right eye-view areas is interleaved, so that the stereoscopic image can be stereoscopically generated. image. It should be understood that the above method flow may further reduce, add, and merge the steps therein, and the invention may still be completed, for example, directly using image information as a classification to omit the classification step.
