Description

Non-fungible token three-dimensional display device with built-in electronic wallet and three-dimensional display method thereof

The present invention relates to a three-dimensional display device and a three-dimensional display method thereof, in particular to a non-homogeneous token three-dimensional display device with a built-in electronic wallet and a three-dimensional display method thereof.

In recent years, with the popularization and vigorous development of panel technology, various panel applications have mushroomed, such as monitors, mobile phone screens, digital photo frames, etc. Among them, in addition to well-known applications such as monitors and mobile phone screens, the application of digital photo frames is also becoming more and more common.

Generally speaking, traditional digital photo frames can display digital photos or images. Different from ordinary photo frames, digital photo frames can easily change the displayed photos or images, and can even dynamically play multiple pictures or images in turn. They are no longer limited to Fixed photos or images are therefore widely loved by users, and it can even be seen that large-size digital photo frames replace traditional advertising billboards. However, with the development of technology, especially the evolution of Non-Fungible Tokens (NFTs), it is no longer rare for creators to choose to publish their works in the form of NFTs. Users have begun to expect digital photo frames to have displays. capabilities of NFT works, and at the same time, we hope to highlight the particularity and confidentiality of NFT owners. For example, only NFT owners can browse or obtain a better or more special browsing experience, and it is expected that NFT works will be difficult to It is distributed on the Internet for anyone to watch or download at will. Therefore, how to maintain the confidentiality and collection value of NFT works by improving display technology has become an urgent problem that various manufacturers want to solve.

In fact, the digital photo frame 100 can include a frame 110 and a display module 130 as shown in "Figure 1". The display module 130 includes a backlight plate 131, a polarization control unit 133, and a transmissive display unit 135. The polarization control unit 133 includes Multiple polarizing elements. The polarizing elements in the polarization control unit 133 can be driven as shown in "Figure 2" to form a series of stripes of multiple parallax barriers 210 (Parallax Barrier). The light emitted by the backlight plate 131 passes through the Each pixel line (such as each row of pixels) included in the display unit 135 can be emitted in a specific direction through the parallax barrier 210, so that the viewer can stand at a specific angle to view the display of each specific pixel line. image screen. Next, the display module 130 can provide five different viewing angles as shown in "Figure 2", that is, it can display five image frames, so that the left eye of the viewer 251 can see through each pixel line (221, 224, 227), the right eye can see the image displayed by the light passing through each pixel line (222, 225, 228). Similarly, the left eye of the viewer 253 and the viewer 255 can see the image displayed by each pixel line (222, 225, 228), and the right eye can see the image displayed by each pixel line (223, 226, 229). image screen. In addition, in other embodiments, the relative positions of the transmissive display unit 135 and the polarization control unit 133 may be interchanged. In this way, two-dimensional digital photos can have a three-dimensional display effect and obtain a more diverse display experience. However, because digital photo frames simulate images from different viewing angles based on two-dimensional digital photos, the digital photos displayed stereoscopically may be distorted or blurred. In addition, current digital photo frames with three-dimensional display capabilities are also limited by hardware. The problem is that it can only display static digital photos in 3D, but cannot display videos in 3D. Therefore, even if the digital photo frame has the three-dimensional display capability of NFT, it still cannot effectively maintain the display quality and uniqueness of NFT works without changing the source picture or image, with distortion and blur, and because only static images are allowed to be displayed Image, does not support dynamic images, so there is a problem of insufficient display diversity of non-fungible tokens.

To sum up, it can be seen that the problem of insufficient display diversity of non-fungible tokens has long existed in previous technologies. Therefore, it is necessary to propose improved technical means to solve this problem.

Source image. This multi-source image contains M image data with different capture angles and time synchronization. The multi-source image has multiple frames. Each frame contains M pixel blocks, and each pixel block contains an image. The image frame contained in the pixel blocks arranged at the same position in each frame is the image of the same image data at different times, where M is a positive integer; the processing module continuously reads out each frame from the multi-source image The image frames in all the pixel blocks included are used to obtain M pieces of image data; the transparent display unit displays the image frame of the nth image data in i pixel lines separated by M-1 pixel lines, where , i and n are both positive integers and 1≦n≦M; and the polarization control unit controls the polarization element to form multiple parallax barriers, so that the nth image is displayed by i pixel lines separated by M-1 pixel lines.

The embodiments of the present invention will be described in detail below with reference to the drawings and examples, so that the implementation process of how to apply technical means to solve technical problems and achieve technical effects of the present invention can be fully understood and implemented accordingly.

Before describing the non-fungible token three-dimensional display device with built-in electronic wallet and its three-dimensional display method disclosed in the present invention, the terms defined by the present invention are first explained. The "multi-source image" mentioned in the present invention includes Multiple image data are captured at different angles and synchronized in time. Therefore, the frame of the multi-source image has multiple pixel blocks to display the image frames of each image data respectively. In actual implementation, multi-source images can be generated by using different image capture devices to shoot at the same time but from different angles. This multi-source image represents a work of non-fungible tokens, which means that the creator will His works (i.e., multi-source images) are published on the blockchain in the form of non-fungible tokens. However, the actual files of the multi-source images are usually not stored on the blockchain, but are pointed to through uniform resource identifiers. The actual storage address of multi-source image files; and stored in a decentralized storage method. In addition, the "pixel line" refers to multiple pixels arranged in the same row or column. Each pixel line is used to display corresponding pixel information. For example, an image can be regarded as composed of multiple pixels. Composed of information, each pixel line can display the corresponding three primary colors of the pixel (red, green, blue), etc. according to the corresponding pixel information.

The following is a further explanation of the non-fungible token three-dimensional display device with built-in electronic wallet of the present invention and its three-dimensional display method with reference to the drawings. Please refer to "Figure 3" first. "Figure 3" shows the present invention with built-in electronic wallet. A device block diagram of a wallet's non-fungible token three-dimensional display device. The three-dimensional display device includes: an electronic wallet 310, a processing module 320, and a display module 330. Among them, the electronic wallet 310 is connected to the blockchain through the blockchain module 321 of the processing module 320. In practical implementation, the electronic wallet is a cryptocurrency wallet that is continuously connected to the blockchain, or is only connected to the blockchain when it is necessary to display the works of non-fungible tokens.

The processing module 320 is used to execute computer instructions and is responsible for obtaining multi-source images and extracting the image data contained in the multi-source images from the obtained multi-source images. In fact, after executing the computer instructions, a blockchain will be generated: Module 321, work acquisition module 322, image reading module 323 and image output module 324. Among them, the blockchain module 321 is used to drive the electronic wallet 310 to connect to the blockchain, and read the non-fungible tokens held by the electronic wallet 310 from the blockchain to obtain corresponding metadata. This metadata includes Uniform resource identifiers to point to multi-source images representing a work. In actual implementation, non-fungible tokens are generated through mint based on metadata. Generally speaking, the works represented by non-fungible tokens are not stored on the blockchain, but are identified through unified resources. symbol (e.g. file path, URL, etc.) pointing to its location.

The work acquisition module 322 is used to obtain multi-source images through uniform resource identifiers. The multi-source images include M image data with different capture angles and time synchronization. The multi-source images have multiple frames, and each frame includes M Pixel blocks, each pixel block contains an image frame, and the image frames contained in the pixel blocks arranged at the same position in each frame are images of the same image data at different times, where M is a positive integer. In other words, the work acquisition module 322 is responsible for acquiring multi-source images. In actual implementation, the image data contained in the multi-source images are captured at the same time at different capture angles (ie, different viewing angles), such as As shown in "Figure 4", multiple image capture devices (411-425) simultaneously capture images of the shooting target 430 at different capture angles to generate synchronized image data. Generally speaking, the shooting targets in the image data included in the multi-source images are the same, but the present invention is not limited to this. For example, some image capture devices that generate image data shoot a specific target, and another part generates images. The data image capture device captures the surrounding environment of a specific target, etc. Among them, the image capture devices (411-425) are usually cameras, but the present invention is not limited thereto. For example, the image capture devices (411-425) can also be mobile phones or digital cameras.

In addition, for example, each frame includes M pixel blocks (in some embodiments, there may be more than M image blocks). As shown in "Figure 5", the frame 500 includes 25 pixel blocks. For example, the pixel block 511 is one of them, but the invention is not limited thereto. The size and number of pixel blocks contained in all frames in the multi-source image are the same, and each pixel block of each frame in the multi-source image contains an image frame of image data from a different perspective. The above-mentioned image A picture is also a frame of an image material. In particular, since the time of all image data contained in a multi-source image is synchronized, the time of each frame (image frame) of the image data contained in the pixel block of the same frame in the multi-source image is also synchronized, that is, All image frames contained in a pixel block of the same frame in a multi-source image are captured at the same time. Generally speaking, the positions of the image frames of each image data contained in the multi-source image are fixed in all frames of the multi-source image. That is to say, the pixel blocks are arranged at the same position in the frames of the multi-source image. , the images contained in it are images of the same image data at different times. For example, if the image frames of the image data captured by the image capture device 411 are arranged in the pixel block 511 in the uppermost left corner of the frame 500, then in all frames of the multi-source image, the image frames of the image data captured by the image capture device 411 The image frames of the captured image data are all fixedly arranged in the pixel block 511 in the upper left corner.

It should be noted in particular that the position of the pixel block corresponding to the image frame of each image data in the multi-source image in each frame of the multi-source image can be determined based on the capture angle of each image data, that is, it can be based on the generation of each image data. The relative position of the image capture device of the image data is determined. In some embodiments, the relative position of each image capture device can be determined based on the device identification data of each image capture device, for example, based on the size order of the device identification data. The relative position of each image capture device, etc. The device identification data includes but is not limited to the network address, the number or serial number set by the user, etc. For example, if there are 25 cameras (i.e., image capture devices) that generate image data, assuming that according to the position of the cameras relative to the shooting target, they are cameras No. 1 to No. 25 from left to right (the device identification data is 1 ~25), then the image frame of the image data generated by the image captured by the No. 1 camera can be arranged in the pixel block 511 in the upper left corner of the frame 500 of the multi-source image, and the image data of the image data generated by the No. 2 camera The images can be arranged in the pixel block 512, the images produced by cameras No. 3 to 5 can be arranged in the pixel blocks (513~515), and the images produced by cameras No. 6 to 10 can be arranged in sequence in the frame 500. The pixel blocks in the second column (521~525), and so on, the images produced by cameras No. 11 to 15 can be arranged in the third column of the frame 500, and the images produced by cameras No. 16 to 20 can be arranged sequentially in the third column of the frame 500. The image frames can be arranged in the fourth column of the frame 500 in sequence, and the image frames produced by cameras No. 21 to 25 can be arranged in the fifth column of the frame 500 in sequence.

In actual implementation, the work acquisition module 322 can receive multi-source images through the Internet, or from the decentralized storage InterPlanetary File System (IPFS), or through a decentralized storage protocol or centralized storage service Receive multi-source images, or directly calculate and generate multi-source images based on metadata using algorithms and smart contracts based on generative art. For example, if the field originally used to store the Uniform Resource Identifier is changed to store the JavaScript source code (Source Code), it means that multi-source images are calculated and generated directly based on the JavaScript source code in the metadata based on generative art.

The image reading module 323 is used to continuously read the image frames in all pixel blocks included in each frame from the multi-source images to obtain M pieces of image data. In actual implementation, the position of the image frame in each pixel block depends on the capture angle of each image data, or the relative position, device identification data or arrangement order of different image capture devices that generate M image data. . In addition, the position of the image frame in each pixel block is recorded in the header of the multi-source image, or in the pixel block included in the frame. Furthermore, if the position of the image frame of each image data in the multi-source image corresponding to the pixel block in each frame of the multi-source image depends on the capture angle of each image data, that is, the image frame of the image data is in The position in the frame of the multi-source image depends on the relative position (or device identification data) of the image capture device that generates each image data. Then the image reading module 323 can read from the multi-source image in order from left to right and top to bottom. Images of each image data are read out sequentially in each frame of the image, and image data can be generated based on the time sequence of the read image frames in the multi-source image. If the position of the pixel block corresponding to the image frame of each image data in the frame of the multi-source image is not defined, that is, the position of the pixel block corresponding to the image frame of each image data in the frame of the multi-source image. The position can be determined arbitrarily, and the image reading module 323 can be recorded in the header of the multi-source image to represent the arrangement order of the image capture devices included in each pixel block in the frame that generates the multi-source image ( or relative position or capture angle or device identification data), read the image of each image data from each frame of the multi-source image, and can arrange the read images according to the timing of the read image frame in the multi-source image Images are used to generate images captured by each image capturing device. In some embodiments, the arrangement order of the image capture devices (or relative position or capture angle or device identification information) is not limited to being recorded in the header of the multi-source image, but can also be recorded in the frame of the multi-source image. A block of pixels that does not contain an image frame. For example, when the frame of a multi-source image is divided into 25 pixel blocks and the multi-source image contains 24 or less image data, the unused pixel blocks can record the arrangement order (or relative order) of the image capture devices. position or capture angle or device identification data) and/or the arrangement order of the image frames contained in each pixel block in the frame of the multi-source image (or the relative position or capture angle or device identification data being captured), The unused pixel blocks can be at any position in the frame of the multi-source image, and the present invention has no particular limitation.

The image output module 324 is used to output the M image data obtained by the image reading module 323. In actual implementation, the output method can be through: VGA (Video Graphics Array), High Definition Multimedia Interface (HDMI), Digital Visual Interface (DVI) or similar wires or buses Wait, and output the image data to the display module 330. In other words, the image output module 324 is responsible for the arrangement order (or relative position or capture angle) of the image capture devices in the image frames in all pixel blocks included in each frame read by the image reading module 323 or device identification data), each image frame is output to the display module 330 respectively, so that the display module 330 displays different image data at different viewing angles. In more detail, the image output module 324 can output the pixel rows of each image frame to the display module one by one according to the arrangement order (or relative position or capture angle or device identification data) of the image capture devices that generate each image frame. Each corresponding pixel line in the group 330, for example, when the multi-source image contains 25 image data, the image capture device that generates these 25 image data will be ranked first according to the relative position or capture angle order. to the 25th image capture device. At this time, the image output module 324 can output the k-th pixel information of the image frame in the image data generated by the j-th image capture device to the display module 330 for display. The k-th pixel line of the j-th viewing angle, where j and k are positive integers, will be further described later in conjunction with the embodiment.

The display module 330 includes: a transmissive display unit 331 and a polarization control unit 332. Among them, the transparent display unit 331 includes a plurality of pixel lines, and displays the image frame of the n-th image data output by the image output module in i pixel lines separated by M-1 pixel lines, where, Both i and n are positive integers and 1≦n≦M. For example, when n is a value of 1 and M is a value of 5, the transparent display unit 331 will display i pixel lines separated by 4 pixel lines (i.e., the 1st, 6th, 11th, 16, and so on to the i-th pixel line) to display the first image frame. In actual implementation, the transparent display unit 331 may be a conventional liquid crystal panel in a display, and is responsible for displaying image frames in all image data output by the image output module 324 .

The polarization control unit 332 includes a plurality of polarization elements. The polarization control unit 332 controls the polarization elements to form a plurality of parallax barriers, so that the i pixel lines separated by M-1 pixel lines display the image frame of the n-th image data. Viewed at corresponding viewing angles, the viewing angles of each pixel line displaying different image data are different, and the relative position of the displayed viewing angle of each image data is the same as the relative position of the captured angle. In actual implementation, the viewer can usually only see the pixel lines displaying the same image data at one viewing angle, so that the viewer can only see the image frame of a specific image data at a specific position. However, if the viewer By moving to different viewing angles, you can see images of different image data.

In addition, the display module 330 may also include a backlight plate 333. The polarization control unit 332 and the backlight plate 333 are respectively disposed on the same side or different sides of the transmissive display unit 331. That is to say, in the display module 330 , the arrangement sequence of the backlight plate 333 , the transmissive display unit 331 , and the polarization control unit 332 may be the backlight plate 333 , the transmissive display unit 331 , and the polarization control unit 332 , or the backlight plate 333 , polarization control unit 332, and transmissive display unit 331. The backlight panel 333 has the same function as the backlight module in a conventional display, and is responsible for providing a light source so that the light source completely or partially penetrates the display unit 331 and reaches the eyes of the viewer.

Assume that the display module 330 includes multiple pixel lines as shown in "Figure 7". When the multi-source image representing the work includes 25 image data (ie: M = 25), the first viewing angle (the first image The first pixel information of the image frame generated by the second viewing angle (generated by the second image capturing device) can be displayed by the first pixel line 701a of the display module 330, and the first pixel information of the image frame from the second viewing angle (generated by the second image capturing device) One piece of pixel information can be displayed by the second pixel line 701b of the display module 330, and by analogy, the first piece of pixel information of the image frame from the 25th perspective (generated by the 25th image capture device) can be displayed. The 25th pixel line 701y of the module 330 displays, and the second pixel information of the image frame from the first viewing angle (generated by the first image capture device) can be displayed by the 26th pixel line 702a of the display module 330 , the second piece of pixel information of the image frame from the second viewing angle (generated by the second image capture device) can be displayed by the 27th pixel line 702b of the display module 330, and by analogy, the 25th viewing angle ( The second pixel information of the image frame generated by the 25th image capture device) can be displayed by the 25th pixel line 702y of the display module 330, and by analogy, all pixel information of all viewing angles is displayed, where j, k They are all positive integers, j is less than or equal to 25, and k is less than or equal to the horizontal resolution of the image. It is worth mentioning that the relative position of the viewing angle at which the j-th image data is displayed is the same as the relative position of the angle at which the same image data is captured. In some embodiments, the image output module 324 can also first convert the image frame read by the image reading module 323 into an image format supported by the display module 330, and then output the format-converted image to Display module 330. In other words, the transmissive display unit 331 will display i pixel lines (the value of i depends on the resolution of the image) separated by 24 lines (i.e., M-1 lines; 25 – 1 = 24). The image frames of all image data, for example: display the image frame of the first image data on the 1st, 26th,... pixel lines (701a, 702a,...); display the image frames of the 1st image data on the 2nd, 27th,... pixel lines (701a, 702a,...) 701b, 702b,...) display the image screen of the second image data, and so on until the image screen of the 25th image data is displayed.

In this way, the first image data (that is, captured by the image capture device 411) displayed by the first, 26th, ... pixel lines (701a, 702a, ...) of the display module 330 through the display unit 331 The image data captured) can be viewed from the rightmost perspective (i.e., the perspective from which the image capture device 411 captures the image data); the 2nd, 27th, ... The image of the second image data (i.e., the image data captured by the image capture device 412) displayed by the ... pixel lines (701b, 702b, ...) can be viewed from the rightmost angle slightly toward the middle. , and by analogy, the 25th image data (i.e., the image capture device 425 The image frame (captured image data) can be viewed from the leftmost perspective (ie, the perspective from which the image capture device 425 captures the image data). At this point, the work of non-fungible tokens can be displayed three-dimensionally without affecting the clarity. At the same time, in addition to displaying static images, the work can also be allowed to be dynamic images, such as movies, animations, and strings. Streaming images and more.

In summary, it can be seen that the difference between the present invention and the prior art is that the electronic wallet built into the stereoscopic display device is connected to the blockchain by driving it, and the non-fungible tokens held by the electronic wallet are read from the blockchain to obtain Corresponding metadata, and then obtain the multi-source image representing the work based on the uniform resource identifier of the metadata, and then display the nth image in the multi-source image one by one in i pixel lines separated by M-1 pixel lines. The image of the image data can be viewed at different viewing angles through the parallax barrier controlled by the display module. This technical means can solve the problems existing in the previous technology, thereby improving the efficiency of non-fungible tokens. Show the technical efficacy of diversity.
