Description

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

Technical Field

The present invention relates to a stereoscopic display device and a stereoscopic display method thereof, and more particularly, to a stereoscopic display device and a stereoscopic display method thereof for a non-homogeneous token with an electronic wallet.

Background

In recent years, with the popularization and vigorous development of panel technology, various applications of panels have emerged as spring bamboo shoots after rain, for example: displays, cell phone screens, digital photo frames, etc. Among them, in addition to applications such as display and mobile phone screen, applications of digital photo frames are becoming more and more popular.

In general, a conventional digital photo frame can display digital photos or images, unlike a general photo frame, the digital photo frame can easily change the displayed photos or images, and even can alternately play a plurality of photos or images in a dynamic manner, and is not limited to fixed photos or images, so that the digital photo frame is popular with users, and even the situation that a large-size digital photo frame replaces a conventional advertisement billboard can be seen. However, with the development of technology, particularly Non-homogeneous Token (NFT), in situations where the creator chooses to publish a work in NFT form, users have come to expect digital photo frames to have the ability to display NFT works, while also being able to highlight the specificity and confidentiality of NFT owners, e.g., only NFT owners are able to browse, or obtain a better or more specific browsing experience, and it is desirable that NFT works be difficult to be disseminated on the network for anyone to watch or download, etc. Therefore, how to maintain the confidentiality and collection value of NFT works by improving display technology is a problem to be solved by various manufacturers.

In practice, as shown in fig. 1, the digital photo frame 100 may include a frame 110 and a display module 130, 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 a plurality of polarization elements, the polarization elements in the polarization control unit 133 may be driven to form a plurality of Parallax barriers 210 (parallelx Barrier) of a series of stripes as shown in fig. 2, and after passing through each pixel line (e.g., each row of pixels) included in the transmissive display unit 135, light emitted by the backlight plate 131 may be emitted in a specific direction through the Parallax barriers 210, so that a viewer may stand at a specific angle to view an image frame displayed by the specific pixel lines. Next, the display module 130 may provide five different viewing angles, i.e. five image frames may be displayed, as shown in fig. 2, so that the left eye of the viewer 251 may see the image frames formed by the light rays of the respective pixel lines (221, 224, 227), and the right eye may see the image frames displayed by the light rays of the respective pixel lines (222, 225, 228). Likewise, the left eye of the viewer 253 and the left eye of the viewer 255 can see the image frames displayed by the respective pixel lines (222, 225, 228), and the right eye can see the image frames displayed by the respective pixel lines (223, 226, 229). In addition, in other embodiments, the relative positions of the transmissive display unit 135 and the polarization control unit 133 may be interchanged. Therefore, the two-dimensional digital photo has a three-dimensional display effect, and a more various display experience is obtained. However, since the digital photo frame simulates images with different viewing angles according to two-dimensional digital photos, the stereoscopic digital photos may be distorted or blurred, and in addition, the current digital photo frame with stereoscopic display capability is limited by hardware problems, only static digital photos can be stereoscopically displayed, but movies cannot be stereoscopically displayed. Therefore, even if the digital photo frame is provided with the stereoscopic display capability of the NFT, the display quality and uniqueness of the NFT work cannot be effectively maintained without changing the source picture or image and having distortion and blurring, and the display diversity of the heterogeneous token is insufficient because only the still image is allowed to be displayed and the moving image is not supported.

In view of the foregoing, it is known that there has been a long-felt need in the art for an improvement in the technical means to solve the problem of insufficient display diversity of non-homogeneous tokens.

Detailed Description

The following detailed description of embodiments of the present invention will be given with reference to the accompanying drawings and examples, by which the implementation process of how the present invention can be applied to solve the technical problems and achieve the technical effects can be fully understood and implemented.

Before describing the three-dimensional display device and the three-dimensional display method of the non-homogeneous token with the built-in electronic wallet, the invention is described in terms of definition, and the multi-source image comprises a plurality of image data with different capturing angles and time synchronization, so that a Frame (Frame) of the multi-source image has a plurality of pixel blocks to respectively display the image frames of the image data. In practical implementation, the generation mode of the multi-source image can be generated by shooting at the same time but different angles through different image capturing devices, the multi-source image represents the work of the heterogeneous token, that is, the creator issues the work (i.e. the multi-source image) on the blockchain through the form of the heterogeneous token, however, the actual file of the multi-source image is not usually stored on the blockchain but points to the actual storage address of the multi-source image file through the uniform resource identifier; and stored in a decentered storage mode. In addition, the "pixel line" refers to a plurality of pixel points arranged in the same row or column, and each pixel line is used for displaying corresponding pixel information, for example, an image frame may be considered to be composed of a plurality of pieces of pixel information, and each pixel line may display three primary colors (red, green, blue) of the corresponding pixel according to the corresponding pixel information.

Referring to fig. 3, fig. 3 is a block diagram of a device of the present invention with a three-dimensional display device of a non-homogeneous token with a built-in electronic wallet, the three-dimensional display device comprises: an electronic wallet 310, a processing module 320 and a display module 330. Wherein the e-wallet 310 is connected to the blockchain through a blockchain module 321 of the processing module 320. In practice, the electronic wallet is a cryptocurrency wallet that may be continuously connected to the blockchain or to the blockchain only when it is desired to display a work of non-homogenous tokens.

The processing module 320 is configured to execute computer instructions for acquiring a multi-source image, and extracting image data included in the multi-source image from the acquired multi-source image, wherein the computer instructions, when executed, actually generate: a blockchain module 321, a work acquisition module 322, an image reading module 323 and an image output module 324. The blockchain module 321 is used to drive the electronic wallet 310 to connect with the blockchain, and reads the non-homogenous tokens held by the electronic wallet 310 from the blockchain to obtain corresponding metadata, wherein the metadata includes a uniform resource identifier to point to a multi-source image representing a work. In practice, non-homogenous tokens are created by casting (Mint) based on metadata, and generally, the work represented by a non-homogenous token is not deposited on a blockchain, but is pointed to its location by a uniform resource identifier (e.g., archive path, web address, etc.).

The work obtaining module 322 is configured to obtain a multi-source image through a uniform resource identifier, where the multi-source image includes M image data with different capturing angles and synchronized time, and the multi-source image has a plurality of frames, each frame includes M pixel blocks, each pixel block includes an image frame, and the image frames included 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 composition obtaining module 322 is responsible for obtaining multi-source images, in which, in practical implementation, the image data included in the multi-source images are obtained by capturing at different capturing angles (i.e. different viewing angles) at the same time, and as shown in fig. 4, the image capturing devices (411-425) simultaneously capture images of the capturing object 430 at different capturing angles to generate synchronous image data. Generally, the image data included in the multi-source image has the same shooting target, but the invention is not limited thereto, for example, the image capturing device partially generating the image data shoots the specific target, and the image capturing device partially generating the image data shoots the surrounding environment of the specific target. The image capturing devices (411-425) are usually video cameras, but the present invention is not limited thereto, and for example, the image capturing devices (411-425) may be mobile phones or digital cameras.

In addition, taking an example that each frame includes M pixel blocks (in some embodiments, there may be more than M image blocks), as shown in fig. 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 included in all frames of the multi-source image are the same, and each pixel block of each frame of the multi-source image includes an image frame of image data of a different viewing angle, which is referred to as a frame of image data. It should be noted that, since the time of all the image data included in the multi-source image is synchronized, the time of the frames (image frames) of the image data included in the pixel blocks of the same frame in the multi-source image is also synchronized, that is, the time of capturing all the image frames included in the pixel blocks of the same frame in the multi-source image is the same. In general, the positions of the image frames of the respective image data included in the multi-source image are fixed in all frames of the multi-source image, that is, the pixel blocks arranged at the same positions in the frames of the multi-source image, and the image frames included in the multi-source image are images of the same image data at different times. For example, if the image frames of the image data captured by the image capturing device 411 are arranged in the pixel block 511 at the top left corner in the frame 500, the image frames of the image data captured by the image capturing device 411 are fixedly arranged in the pixel block 511 at the top left corner in all frames of the multi-source image.

It should be noted 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 may be determined according to the capturing angle of each image data, that is, the relative position of the image capturing device generating each image data may be determined according to the device identification data of each image capturing device, for example, the relative position of each image capturing device is determined according to the order of the size of the device identification data, where the device identification data includes, but is not limited to, a network address, a number or serial number set by a user, and the like. For example, if there are 25 cameras (i.e., image capturing devices) generating image data, it is assumed that the cameras from left to right are respectively one to twenty-five cameras (i.e., 1 to 25 are used as device identification data) according to the positions of the cameras relative to the shooting targets, the first camera captures the image data image frames, which can be arranged in the top left pixel block 511 of the multi-source image frame 500, the second camera generates the image data image frames, which can be arranged in the pixel block 512, the third to five cameras generate the image frames, which can be arranged in the pixel blocks 513 to 515), the sixth to ten cameras generate the image frames, which can be arranged in the second pixel blocks 521 to 525 of the frame 500, and so on, the eleventh to fifteenth cameras generate the image frames, which can be arranged in the third column of the frame 500, the sixteen to twenty-five cameras generate the image frames, which can be arranged in the fourth column of the frame 500, and the twenty-fifteenth cameras generate the image frames, which can be arranged in the fifth column of the frame 500.

In practice, the work acquisition module 322 may receive the multi-source image via a network, or receive the multi-source image from an off-centered stored interstellar archive system (InterPlanetary File System, IPFS), or via an off-centered storage protocol or a centered storage service, or generate the multi-source image directly from metadata calculations based on a generated Art (generated Art) and an algorithm and Smart Contract (Smart contact). For example, assume that a field originally used for storing a uniform resource identifier is instead used for storing JavaScript Source Code (Source Code), which represents generating a multi-Source image based on generation art directly according to JavaScript Source Code calculation in metadata.

The image reading module 323 is used for continuously reading out the image frames in all pixel blocks included in each frame from the multi-source image to obtain M image data. In practice, the position of the image frame in each pixel block depends on the capturing angle of each image data, or the relative positions, device identification data, or arrangement order of different image capturing devices that generate M image data. In addition, the position of each pixel block of the image frame is recorded in the Header (Header) of the multi-source image or in the pixel block included in the frame. Further, if 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 depends on the capturing angle of each image data, that is, the position of the image frame of each image data in the frames of the multi-source image depends on the relative position (or device identification data) of the image capturing device that generates each image data, the image reading module 323 can sequentially read out the images of each image data from each frame of the multi-source image from left to right from top to bottom, and can generate the image data according to the time sequence of the frames of the read-out images in the multi-source image. If the positions of the pixel blocks corresponding to the image frames of the image data in the frame of the multi-source image are not defined, that is, the positions of the pixel blocks corresponding to the image frames of the image data in the frame of the multi-source image may be arbitrarily determined, the image reading module 323 may read the image of each image data from each frame of the multi-source image according to the arrangement order (or the relative position or the acquisition angle or the device identification data) of the image capturing devices recorded in the header of the multi-source image and representing the image frames included in each pixel block in the frame of the multi-source image, and may generate the image captured by each image capturing device according to the time sequence of the frame of the read image in the multi-source image. In some embodiments, the arrangement order (or the relative position or the acquisition angle or the device identification data) of the image capturing devices is not limited to the header of the multi-source image, but may be recorded in a pixel block of a frame of the multi-source image, which does not include an image frame. For example, when the frame of the multi-source image is divided into 25 pixel blocks and the multi-source image contains 24 or less image data, the unused pixel blocks may record the arrangement order (or the relative position or the capturing angle or the device identification data) of the image capturing device and/or the arrangement order (or the captured relative position or the capturing angle or the device identification data) of the image frames contained in each pixel block in the frame of the multi-source image, wherein the unused pixel blocks may be at any position in the frame of the multi-source image, and the invention is not particularly limited.

The image output module 324 is configured to output the M image data obtained by the image reading module 323. In practical implementation, the output mode may be as follows: VGA (Video Graphics Array), high-definition multimedia interface (High Definition Multimedia Interface, HDMI), digital video interface (Digital Visual Interface, DVI) or similar wires or buses, etc., outputs image data to the display module 330. In other words, the image output module 324 is responsible for outputting each image frame to the display module 330 according to the arrangement sequence (or the relative position or the capturing angle or the device identification data) of the image capturing devices of the image frames in all the pixel blocks included in each frame read out by the image reading module 323, so that the display module 330 displays different image data at different viewing angles. In more detail, the image output module 324 may output the pixel lines of each image frame to each corresponding pixel line in the display module 330 one by one according to the arrangement sequence (or the relative position or the capturing angle or the device identification data) of the image capturing devices generating each image frame, for example, when the multi-source image includes 25 image data, the image capturing devices generating the 25 image data are respectively the 1 st to the 25 th image capturing devices according to the arrangement sequence of the relative position or the capturing angle, and at this time, the image output module 324 may output the k pixel information of the image frame in the image data generated by the j-th image capturing device to the display module 330 to display the k pixel line of the j-th viewing angle, where j and k are positive integers, which will be further described in the following embodiments.

In the portion of the display module 330, it includes: the transmissive display unit 331 and the polarization control unit 332. The transmissive display unit 331 includes a plurality of pixel lines, and displays an image of the nth image data outputted by the image output module in i pixel lines spaced by M-1 pixel lines, where i and n are positive integers and 1+.n+.m. For example, when n is 1 and M is 5, the penetration display unit 331 displays the 1 st image frame in the i pixel lines (i.e. 1 st, 6 th, 11 th, 16 th pixel lines) at intervals of 4 pixel lines. In practice, the penetration display unit 331 may be a liquid crystal panel in an existing display, and is responsible for displaying the image frames in all the image data outputted by the image output module 324.

The polarization control unit 332 includes a plurality of polarization elements, and the polarization control unit 332 controls the polarization elements to form a plurality of parallax barriers, so that the image frame of the nth image data displayed by the i pixel lines with M-1 pixel lines as intervals is viewed at the corresponding viewing angle, wherein the viewing angle of each pixel line displaying different image data is different, and the relative position of the viewing angle of each image data is the same as the relative position of the captured angle. In practice, a viewer can usually only see each pixel line 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, but can see the image frames of different image data if the viewer moves to a position with a different viewing angle.

In addition, the display module 330 may further include a backlight 333, and the polarization control unit 332 and the backlight 333 are disposed on the same side or different sides of the transmissive display unit 331. That is, in the display module 330, the arrangement order of the backlight 333, the transmissive display 331, and the polarization control 332 may be the backlight 333, the transmissive display 331, and the polarization control 332, or the backlight 333, the polarization control 332, and the transmissive display 331. The backlight 333 functions as a backlight module in the existing display and is responsible for providing a light source to reach the viewer's eye by penetrating the display unit 331 completely or partially.

Referring to fig. 6A and 6B, fig. 6A and 6B are flowcharts of a method for three-dimensional display of a non-homogeneous token with a built-in electronic wallet according to the present invention, which is applied to a three-dimensional display device 300, wherein the three-dimensional display device 300 comprises an electronic wallet 310, a processing module 320 and a display module 330, the display module 330 comprises a transmissive display unit 331 and a polarization control unit 332, the transmissive display unit 331 comprises a plurality of pixel lines, the polarization control unit 332 comprises a plurality of polarization elements, and the steps comprise: the processing module 320 drives the electronic wallet 310 to connect to the blockchain and reads the non-homogenous tokens held by the electronic wallet 310 from the blockchain to obtain corresponding metadata, wherein the metadata contains a uniform resource identifier to point to a multi-source image representing the work (step 610); the processing module 320 obtains multiple source images through the uniform resource identifier, each of the multiple source images includes M image data with different capturing angles and synchronized time, the multiple source images have multiple frames, each frame includes M pixel blocks, each pixel block includes an image frame, the image frames included in the pixel blocks arranged at the same position in each frame are images of the same image data at different times, wherein M is a positive integer (step 620); the processing module 320 continuously reads out the image frames in all the pixel blocks included in each frame from the multi-source image to obtain M image data (step 630); the pass-through display unit 331 displays an image frame of the nth image data in i pixel lines spaced by M-1 pixel lines, where i and n are positive integers and 1+.n+.m (step 640); the polarization control unit 332 controls the polarization element to form a plurality of parallax barriers, so that the image frame of the nth image data displayed by the i pixel lines with M-1 pixel lines as intervals is viewed at the corresponding viewing angle, wherein the viewing angle of each pixel line displaying different image data is different, and the relative position of the viewing angle at which each image data is displayed is the same as the relative position of the captured angle (step 650). Through the above steps, the electronic wallet 310 built in the stereoscopic display device 300 is driven to connect with the blockchain, and the non-homogeneous tokens held by the electronic wallet 310 are read from the blockchain to obtain corresponding metadata, then the multi-source images representing the works are obtained according to the uniform resource identifier of the metadata, and then the image frames of the nth image data in the multi-source images are displayed one by one in the i pixel lines with M-1 pixel lines as intervals respectively, so that the n-th image data can be watched at different visual angles through the parallax barrier controlled by the display module 330.

Next, as shown in fig. 6B, before step 220, the position of the image frame in each pixel block may be determined according to the capturing angle of each image data, or the relative positions of different image capturing devices generating M image data, device identification data or arrangement order, so as to arrange the image frames of M image data according to the positions of the pixel blocks corresponding to the M image data in each frame, so as to generate a multi-source image representing a non-homogeneous token (step 615).

In the following, referring to fig. 7, fig. 7 is a schematic diagram illustrating an image displayed by each pixel line of the display module according to the present invention. The stereoscopic display device 300 is assumed to be a digital photo frame capable of providing 25 viewing angles. After the user activates the stereoscopic display device 300, the processing module 320 of the stereoscopic display device 300 drives the electronic wallet 310 to connect with the blockchain, and reads the non-homogeneous tokens held by the electronic wallet 310 from the blockchain, so as to obtain the corresponding metadata and obtain the work through the uniform resource identifier contained therein, for example: a multi-source image comprising 25 different acquisition angles and time-synchronized image data. Next, assuming that the image frames in the respective image data included in the multi-source image are sequentially arranged in the pixel area of the frame of the multi-source image according to the position/capturing angle with respect to the photographing target, as in the frame 500 shown in fig. 5, the image frames in the pixel area 511 are the image capturing devices arranged at the leftmost or rightmost of the photographing target, and then the pixel area from left to right contains the frames of the image data generated by the other image capturing devices sequentially arranged from top to bottom, the image reading module 323 in the processing module 320 may read out the image frames of the respective image data from each frame 500 of the multi-source image starting from the pixel area 511 and output to the display module 330 as illustrated in fig. 7.

Assuming that the display module 330 includes a plurality of pixel lines as shown in fig. 7, when the multi-source image representing the work includes 25 pieces of image data (i.e., m=25), the 1 st piece of pixel information of the image frame of the 1 st viewing angle (generated by the 1 st image capturing device) can be displayed by the 1 st pixel line 701a of the display module 330, the 1 st piece of pixel information of the image frame of the 2 nd viewing angle (generated by the 2 nd image capturing device) can be displayed by the 2 nd pixel line 701b of the display module 330, and so on, the 1 st piece of pixel information of the image frame of the 25 th viewing angle (generated by the 25 th image capturing device) can be displayed by the 25 th pixel line 701y of the display module 330, the 2 nd piece of pixel information of the image frame of the 1 st viewing angle (generated by the 1 st image capturing device) can be displayed by the 26 th pixel line 702a of the display module 330, the 2 nd piece of pixel information of the image frame of the 2 nd viewing angle (generated by the 2 nd image capturing device) can be displayed by the 2 nd pixel line 701b of the display module, and all of the j can be displayed by the 25 th pixel line of the display module, and all of the j can be equal to the image frame information of the 25 th viewing angle (generated by the j) of the image frame of the display module) can be displayed by the 25 th pixel line 702, and all of which is equal to the j is equal to the image frame of the image frame information of the 25, and the j is displayed by the image frame of the 25, and the image frame of the image frame has the image frame of the image. It should be noted that the relative position of the viewing angle at which the jth image data is displayed is the same as the relative position of the capturing angle of the same image data. In some embodiments, the image output module 324 may convert the image frame read by the image reading module 323 into the image format supported by the display module 330, and then output the image after the format conversion to the display module 330. In other words, the through display unit 331 displays the image frames of all the image data in i pixel lines (i.e., the value of i depends on the resolution of the image frame) at intervals of 24 (i.e., M-1; 25-1=24), for example: displaying an image screen of the 1 st image data on the 1 st, 26, … … th pixel lines (701 a, 702a, … …); the image frames of the 2 nd image data are displayed on the 2 nd, 27, … … th pixel lines (701 b, 702b, … …), and the image frames of the 25 th image data are pushed out in this manner until the image frames of the 2 nd image data are displayed.

Thus, the image frame of the 1 st image data (i.e. the image data captured by the image capturing device 411) displayed by the 1 st, 26, … … th pixel lines (701 a, 702a, … …) of the penetrating display unit 331 of the display module 330 can be viewed at the right-most viewing angle (i.e. the viewing angle of the image data captured by the image capturing device 411); the image of the 2 nd image data (i.e., the image data captured by the image capturing device 412) displayed on the 2 nd, 27, … … th pixel lines (701 b, 702b, … …) of the penetrating display unit 331 of the display module 330 can be viewed from a rightmost perspective slightly toward the middle, and similarly, the image of the 25 th image data (i.e., the image data captured by the image capturing device 425) displayed on the 25 th, 50, … … th pixel lines (701 y, 702y, … …) of the penetrating display unit 331 of the display module 330 can be viewed from a leftmost perspective (i.e., the image data captured by the image capturing device 425). Thus, the method realizes the stereoscopic display of the work of the non-homogeneous token without affecting the definition, and can display static images and also allow the work to be dynamic images, for example: movies, animations, streaming media images, etc.

In summary, the difference between the present invention and the prior art is that the electronic wallet built in the stereoscopic display device is driven to connect with the blockchain, and the non-homogeneous tokens held by the electronic wallet are read from the blockchain to obtain the corresponding metadata, then the multi-source images representing the works are obtained according to the uniform resource identifier of the metadata, and then the image frames of the nth image data in the multi-source images are displayed one by one in the i pixel lines with the M-1 pixel lines as intervals, so that the nth image data can be viewed from different visual angles through the parallax barrier controlled by the display module, thereby solving the problems existing in the prior art by a technical means and further achieving the technical effect of improving the display diversity of the non-homogeneous tokens.

Although the present invention has been described with reference to the above embodiments, it should be understood that the invention is not limited thereto, but rather may be modified or altered somewhat by persons skilled in the art without departing from the spirit and scope of the invention.
