Description

立體顯示方法 Stereoscopic display method

本發明是有關於一種顯示器的顯示方法，特別是指一種具有跟蹤功能的兩視角裸眼立體顯示器的立體顯示方法。 The present invention relates to a display method for a display, and more particularly to a stereoscopic display method for a two-view naked-eye stereoscopic display having a tracking function.

目前市面上較為普遍的裸眼立體顯示器為兩視角裸眼立體顯示器，它可以將左右眼格式的內容透過光柵分光播放，在一固定的距離形成一個觀賞平面，只要觀賞者站在一固定的位置便可觀賞到正確的立體效果，也就是右眼接受右眼影像，左眼接受左眼影像。若右眼接受左眼影像，左眼接受右眼影像則無法看到立體效果，稱之為逆視，逆視區域也稱為死角。 The naked-eye stereoscopic display currently on the market is a two-view naked-eye stereoscopic display, which can play the left and right eye format through the grating splitting light to form a viewing plane at a fixed distance, as long as the viewer stands in a fixed position. Observe the correct stereo effect, that is, the right eye accepts the right eye image and the left eye accepts the left eye image. If the right eye accepts the left eye image and the left eye accepts the right eye image, the stereoscopic effect cannot be seen, which is called a reverse view, and the reverse view area is also called a dead angle.

更佳的，當該偵測鏡頭1偵測到該使用者雙眼的該所在位置改變，則本實施例的操作方法則進到該步驟(A)以重新利用該偵測鏡頭1重新偵測該使用者之一所在位置。 Preferably, when the detecting lens 1 detects that the position of the user's eyes is changed, the operation method of the embodiment proceeds to the step (A) to re-detect the detecting lens 1 The location of one of the users.

在此舉一例更進一步的說明，如圖3所示，當該使用者的雙眼面對該螢幕6，且位於一第一位置時，該偵 測鏡頭1偵測該使用者雙眼所在的該第一位置而得到一位置資訊11，並藉由該座標判定模組2將該位置資訊11轉換成該座標資訊21，而傳送至該顯示控制模組3，該顯示控制模組3則根據該座標資訊21產生該具有一第一左側影像L1和一第一右側影像R1的影像資訊31，再將該等影像L1、R1傳送至該影像處理模組4，利用該影像處理模組4將該等影像L1、R1傳送至該螢幕6進行播放，此時，該使用者左眼和右眼分別看到該第一左側影像L1和該第一右側影像R1，而該使用者雙眼的視差融合成一立體視角影像41。 In this case, an example is further illustrated. As shown in FIG. 3, when the user's eyes face the screen 6, and are located at a first position, the Detective The measuring lens 1 detects the first position of the user's eyes to obtain a position information 11, and converts the position information 11 into the coordinate information 21 by the coordinate determining module 2, and transmits the position information to the display control. The module 3, the display control module 3 generates the image information 31 having a first left image L1 and a first right image R1 according to the coordinate information 21, and then transmits the images L1 and R1 to the image processing. The module 4 uses the image processing module 4 to transmit the images L1 and R1 to the screen 6 for playing. At this time, the left and right eyes of the user respectively see the first left image L1 and the first image. The right image R1, and the parallax of the user's eyes merge into a stereoscopic view image 41.

當該使用者往左側移動至一第二位置時，該偵 測鏡頭1偵測到該使用者雙眼的該所在位置有所變動後，即重新對該使用者雙眼所在的該第二位置進行偵測，而得到另一位置資訊11，並利用該座標判定模組2將該位置資訊11轉換成一座標資訊21，並將判定後的該座標資訊21送至該顯示器控制模組3，該顯示器控制模組3即根據該座標資訊21產生該具有一第二左側影像L2和一第二右側影像R2的影像資訊31，再將該等影像L2、R2傳送至該影像處理模組4，利用該影像處理模組4將該等影像L2、R2傳送至該螢幕6進行播放，此時，該使用者的左眼接收該第二左側影像L2，而該使用者的右眼則接收該第二右側影像R2，因此，該使用者則能在該第二位置上觀賞到另一立體視角影像41。 When the user moves to the left to a second position, the Detect After detecting that the position of the user's eyes changes, the camera 1 re-detects the second position where the user's eyes are located, and obtains another location information 11 and uses the coordinates. The determining module 2 converts the position information 11 into a bid information 21, and sends the determined coordinate information 21 to the display control module 3, and the display control module 3 generates the first according to the coordinate information 21. The image information 31 of the left image L2 and the second image R2 are transmitted to the image processing module 4, and the image processing module 4 transmits the images L2 and R2 to the image. The screen 6 is played. At this time, the left eye of the user receives the second left image L2, and the right eye of the user receives the second right image R2. Therefore, the user can be in the second position. Another stereoscopic view image 41 is viewed on the top.

綜上所述，該使用者雙眼位於該螢幕6前的該 第一位置時，看到的是該第一左側影像L1和該第一右側影像R1，當該使用者移到該第二位置時，該影像處理模組4會產生該第二左側影像L2和該第二右側影像R2。如此一來，不論該使用者位於該第一位置、該第二位置或是任意位置均可觀賞到不同位置的視角影像41。除了能有跟蹤該使用者雙眼的位置，讓該使用者雙眼能隨時看到立體影像的效果，更同時改善了立體影像觀看的品質，故確實能達成本發明之目的。 In summary, the user's eyes are located in front of the screen 6. In the first position, the first left image L1 and the first right image R1 are seen. When the user moves to the second position, the image processing module 4 generates the second left image L2 and The second right image R2. In this way, the view image 41 of different positions can be viewed regardless of whether the user is located at the first position, the second position, or any position. In addition to being able to track the position of the user's eyes, the user can see the effect of the stereoscopic image at any time, and at the same time improve the quality of the stereoscopic image viewing, so the object of the present invention can be achieved.

惟以上所述者，僅為本發明之實施例而已，當 不能以此限定本發明實施之範圍，即大凡依本發明申請專利範圍及專利說明書內容所作之簡單的等效變化與修飾，皆仍屬本發明專利涵蓋之範圍內。 However, the above is only an embodiment of the present invention, when The scope of the present invention is not limited thereto, that is, the simple equivalent changes and modifications made by the present invention in the scope of the invention and the patent specification are still within the scope of the invention.
