Detailed ways

Please refer to FIG. 1 , which is a schematic flow diagram of a process 10 according to Embodiment 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:

Step 100: start.

Step 102: Store display data of a first image.

Step 104: Detect an action state to generate state information.

Step 106: According to the state information, extract the display data of a second image from the display data of the first image.

Step 108: Display the second image.

Step 110: end.

According to the process 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 the process 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, the process 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.

Please refer to FIG. 2 , which is a schematic diagram of the relationship between a space 20 and the first image. The space 20 includes planes 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 the space 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 the plane 22 and projects a display screen 32 with the letter “A”.

Please refer to FIG. 4 , which is a schematic diagram of a glasses display 40 operating in the space 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 the glasses display 40 is facing the center of the plane 24 , the user can see the display screen with the letter “O”.

It should be noted that, for the convenience of describing the concept of the present invention, the projection device 30 and the glasses display 40 are only used to present images of specific letters. In fact, the projection device 30 and the glasses display 40 can be used to present a continuous image. For example, when the projection device 30 turns to the intersection of the planes 22 and 28 , through the image processing method, the projection device 30 projects fragment images of both letters "A" and "I".

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 the space 20 of the three-dimensional virtual environment.

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.

Regarding the implementation of the process 10, please refer to FIG. 5 , which is a functional block diagram of a display device 50 according to Embodiment 1 of the present invention. The display device 50 includes a storage unit 500 , a motion detection unit 510 , an image processing unit 520 and a display module 530 .

The flat panel display 62 includes a storage unit 600 , a motion detection unit 610 , an image processing unit 620 and a display module 630 . The storage unit 600 is used for storing display data IMG1' of a first image 66. The motion detection unit 610 includes an image capture device 612 for obtaining an image data LOC_IMG about the position of the user 64, and a calculation unit 614 for calculating the distance between the flat panel display 62 and the user 64 according to the image data LOC_IMG. Relative positional relationship, and then generate a state information MOV_INFO'. The image processing unit 620 is used for extracting the display data IMG2' corresponding to the second image 68 from the display data IMG1' of the first image 66 according to the status information MOV_INFO'. The display module 630 is used to display the second image 68 for the user 64 to watch.

In FIG. 7 , the flat panel display 62 stores a first image 66 and displays a second image 68 for a user 64 to watch. In FIG. 8 , the user 64 moves to the left in FIG. 8 , and the flat-panel display 62 detects that the position relative to the user 64 changes, thereby changing the content of the second image 68 . In this way, the flat panel display 62 can give the user 64 a feeling similar to enjoying the scenery through a viewing window.
