具体实施方式Detailed ways

请参考图1，图1为本发明实施例一流程10的流程示意图。流程10通过一显示装置显示与一使用者或一封闭空间互动的影像，其包含有下列步骤：Please refer to FIG. 1 , which is a schematic flow diagram of aprocess 10 according toEmbodiment 1 of the present invention.Process 10 uses a display device to display images interacting with a user or an enclosed space, which includes the following steps:

步骤100：开始。Step 100: start.

步骤102：储存一第一影像的显示数据。Step 102: Store display data of a first image.

步骤104：侦测一动作状态，以产生一状态信息。Step 104: Detect an action state to generate state information.

步骤106：根据该状态信息，从该第一影像的显示数据中撷取出一第二影像的显示数据。Step 106: According to the state information, extract the display data of a second image from the display data of the first image.

步骤108：显示该第二影像。Step 108: Display the second image.

步骤110：结束。Step 110: end.

根据流程10，本发明实施例通过侦测动作状态，取得显示器本身或相对的位置及动作的状态信息，并根据状态信息，显示第一影像中对应的第二影像。在流程10中，根据不同显示装置，侦测动作状态的内容可包含显示装置的转动方位、与一空间或一使用者相对的相对位置关系。为了得到与使用者的相对位置关系，流程10先取得关于使用者的位置的一影像数据，并根据该影像数据，计算显示装置与使用者的相对位置关系，以产生状态信息。According to theprocess 10, the embodiment of the present invention obtains the state information of the display itself or its relative position and action by detecting the action state, and displays the corresponding second image in the first image according to the state information. In theprocess 10, according to different display devices, the content of detecting the action state may include the rotation orientation of the display device, the relative positional relationship with a space or a user. In order to obtain the relative positional relationship with the user, theprocess 10 first obtains an image data about the user's position, and calculates the relative positional relationship between the display device and the user according to the image data, so as to generate status information.

请参考图2，图2为一空间20与第一影像的关系示意图。空间20包含平面22、24、26及28，其所对应的第一影像的显示画面分别为字母“A”、“O”、“I”及“C”。请参考图3，图3为本发明实施例操作于空间20中的一投影装置30的示意图。投影装置30通过侦测本身的转动方位，从第一影像中撷取并投影出对应的影像。在图3中，投影装置30正对平面22的中心位置，并投影出具有字母“A”的一显示画面32。Please refer to FIG. 2 , which is a schematic diagram of the relationship between aspace 20 and the first image. Thespace 20 includesplanes 22 , 24 , 26 and 28 , and the corresponding display frames of the first image are letters “A”, “O”, “I” and “C” respectively. Please refer to FIG. 3 , which is a schematic diagram of a projection device 30 operating in thespace 20 according to an embodiment of the present invention. The projection device 30 captures and projects a corresponding image from the first image by detecting its own rotation orientation. In FIG. 3 , the projection device 30 faces the center of theplane 22 and projects a display screen 32 with the letter “A”.

请参考图4，图4为本发明实施例操作于空间20中的一眼镜显示器40的示意图。在图4中，一使用者配戴眼镜显示器40。当使用者转动头部带动眼镜显示器40转动时，眼镜显示器40根据本身的转动方位，显示对应的影像给使用者。由于眼镜显示器40正对平面24的中心位置，因此使用者可看到具有字母“O”的显示画面。Please refer to FIG. 4 , which is a schematic diagram of a glasses display 40 operating in thespace 20 according to an embodiment of the present invention. In FIG. 4 , a user wears glasses display 40 . When the user turns the head to drive the glasses display 40 to rotate, the glasses display 40 displays corresponding images to the user according to its own rotation orientation. Since theglasses display 40 is facing the center of theplane 24 , the user can see the display screen with the letter “O”.

特别注意的是，为求方便说明本发明概念，上述投影装置30及眼镜显示器40仅用来特别呈现特定字母的影像。实际上，投影装置30及眼镜显示器40可用来呈现一连续影像。举例来说，当投影装置30转向平面22及28的交界处时，通过影像处理方法，投影装置30投影出字母“A”及“I”两者的片段影像。It should be noted that, for the convenience of describing the concept of the present invention, the projection device 30 and theglasses display 40 are only used to present images of specific letters. In fact, the projection device 30 and theglasses display 40 can be used to present a continuous image. For example, when the projection device 30 turns to the intersection of theplanes 22 and 28 , through the image processing method, the projection device 30 projects fragment images of both letters "A" and "I".

由上可知，第一影像包含数个二维影像(如“A”和“O”)，用来呈现三维的空间20，以达成虚拟环境。特别注意的是，第一影像不限制于二维影像的呈现，亦可为一三维影像的表现。举例来说，图2的第一影像的字母“A”、“O”、“I”及“C”影像可变更为三维影像，其包含两组二维影像，而使用者则佩带可利用这两组二维影像产生视差的特殊眼镜来观看三维虚拟环境的空间20。It can be seen from the above that the first image includes several two-dimensional images (such as “A” and “O”), which are used to present the three-dimensional space 20 to achieve a virtual environment. It should be noted that the first image is not limited to the representation of a 2D image, but can also be a representation of a 3D image. For example, the letter "A", "O", "I" and "C" images of the first image in FIG. Two sets of two-dimensional images produce parallax special glasses to watch thespace 20 of the three-dimensional virtual environment.

特别注意的是，本发明实施例的三维影像不限于上述之视差显示技术与投影装置，亦可为用于立体投射的三维影像。在此情况下三维影像资料包含显示图像资料及空间向量资讯，其投影装置则根据转动方位，撷取对应的图像资料及空间向量资讯，其即为第二影像的显示资料。It should be noted that the 3D image in the embodiment of the present invention is not limited to the above-mentioned parallax display technology and projection device, and may also be a 3D image for stereoscopic projection. In this case, the 3D image data includes display image data and space vector information, and the projection device captures the corresponding image data and space vector information according to the rotation orientation, which is the display data of the second image.

关于流程10的实现，请参考图5，图5为本发明实施例一显示装置50的功能方块示意图。显示装置50包含有一储存单元500、一动态侦测单元510、一影像处理单元520及一显示模块530。储存单元500用来储存一第一影像的显示数据IMG1。动态侦测单元510用来侦测显示装置50的一转动方位，以产生一状态信息MOV_INFO。影像处理单元520用来根据状态信息MOV_INFO，从第一影像的显示数据IMG1中撷取出一第二影像的显示数据IMG2。显示模块530则用来显示第二影像(如图3显示画面32)。Regarding the implementation of theprocess 10, please refer to FIG. 5 , which is a functional block diagram of adisplay device 50 according toEmbodiment 1 of the present invention. Thedisplay device 50 includes astorage unit 500 , amotion detection unit 510 , animage processing unit 520 and adisplay module 530 . Thestorage unit 500 is used for storing display data IMG1 of a first image. Themotion detection unit 510 is used to detect a rotation orientation of thedisplay device 50 to generate a state information MOV_INFO. Theimage processing unit 520 is used for extracting the display data IMG2 of a second image from the display data IMG1 of the first image according to the status information MOV_INFO. Thedisplay module 530 is used to display the second image (as shown in the display screen 32 in FIG. 3 ).

因此，在显示装置50中，动态侦测单元510可侦测显示装置50的动作状态，使得影像处理单元520可据以由显示数据IMG1中撷取出显示数据IMG2，并通过显示模块530显示对应的第二影像。显示装置50用以实现流程10，其可以是投影装置30或眼镜显示器40，本领域具通常知识者当可根据不同需求，作适当的修改，而不限于此。Therefore, in thedisplay device 50, themotion detection unit 510 can detect the action state of thedisplay device 50, so that theimage processing unit 520 can extract the display data IMG2 from the display data IMG1 accordingly, and display the corresponding display data through thedisplay module 530.
