The second device needs to scan the QR code displayed on the first device for connection pairing. However, the interaction path of scanning QR codes is long and not convenient enough. Summary of the invention

[0004] The embodiment of the present application provides a method and electronic device for information transmission. In the technical solution, the second electronic device can scan the image displayed by the first electronic device to obtain the first information therein, so as to realize information transmission between the two. For example, when replacing a new device or cloning data, the device interaction path can be shortened and the sense of technology can be enhanced.

[0005] In a first aspect, the present application provides a system comprising a first electronic device and a second electronic device, wherein the first electronic device is used to send a first message, and the first message is used to discover devices around the first electronic device; the second electronic device is used to: receive the first message; and send a first indication information according to the first message; the first electronic device is also used to display a first image according to the first indication information, and the first image includes a first part and a second part; the second electronic device is also used to: acquire N frames of first images, each frame of the N frames of the first images includes a first part and a second part, and positions of the second parts of two adjacent frames of the N frames are the same, wherein N is greater than or equal to 2; and decode the first information according to the second part.

[0006] It should be understood that the first part may be the background of the first image, and the second part may be the part of the first image encoding the first information. Exemplarily, the second part may be superimposed on the first part.

[0008] The device connection information may include, but is not limited to, a connection pairing code, a product serial number, or a media access control MAC address.

[0009] The first indication information may be used to indicate that there are devices around the first electronic device, or the first indication information may be confirmation information after the first message is scanned.

[0010] It should also be understood that the embodiments of the present application do not limit the specific operations performed by the second electronic device after acquiring the first information.

[0011] In other examples, the colors of the second parts of two adjacent frames of images in N frames of images may be different. Alternatively, the colors of the second parts of any three consecutive frames of images in N frames of images may be different, which is not limited in the embodiment of the present application.

[0012] In other examples, the second parts of two adjacent frames of images in N frames of images can encode the same information or different information. When encoding different information, the first electronic device can divide the information to be encoded into multiple parts and encode them in the second parts of images of different frames respectively. Alternatively, multiple consecutive frames of images in N frames of images can encode different information, and multiple groups of information can be encoded in the N frames of images, which is not limited in the embodiments of the present application.

[0013] In other examples, the first parts of two adjacent frames of images in N frames of images may be the same or different, which is not limited in the embodiments of the present application.

[0014] Based on the system provided in the embodiment of the present application, the first electronic device can encode the first information to be transmitted in the second part of the first image, and the second electronic device can obtain N frames of the first image and decode the first information based on the second part.

[0015] For example, when connecting devices, the second electronic device can scan or take a picture of the image displayed by the first electronic device to obtain the device connection information (connection pairing code), so that the device connection can be quickly established. When replacing a new device or cloning data, the device interaction path can be shortened and the sense of technology can be enhanced.

[0016] In some implementations, before the second electronic device decodes the first information according to the second part, the second electronic device is further configured to: perform color space conversion on the N frames of first images to obtain N frames of second images.

[0017] Based on the embodiment of the present application, the second electronic device can reduce the impact of reflections in the first image by performing color space conversion on the first image.

[0018] For example, the first image is converted from the RGB color space to the HSV color space, or the hue, saturation, brightness HSI color space, etc.

[0019] In some implementations, the second electronic device is specifically used to: convert N frames of first images from a red, green, and blue (RGB) color space into a hue, saturation, and brightness (HSV) color space; filter the hue H domain of each frame of the N frames of first images to obtain N frames of second images, wherein the angle value corresponding to the hue H domain included in the second images is greater than a first preset value and less than a second preset value; binarize the N frames of second images to obtain N frames of third images; and determine the second part based on the N frames of third images.

[0020] It should be understood that the embodiment of the present application does not limit the specific values ​​of the first preset value and the second preset value.

[0021] Based on the embodiments of the present application, through the conversion of the color space and the corresponding threshold filtering, the reflection phenomenon in the first image can be filtered out, the interference of the reflection on the second electronic device obtaining the second part can be reduced, and the possibility of successful decoding can be improved.

[0023] Based on the embodiment of the present application, the second part is determined by a closed operation, which can reduce the interference of reflection on the second electronic device obtaining the second part, and improve the possibility of successful decoding. In addition, in the case where the second part is more blocked or severely reflected, the second part can still be successfully obtained through the results of cluster analysis, which improves the possibility of the electronic device successfully decoding the second part later.

[0024] In some implementations, before the second electronic device performs cluster analysis on the N frames of third images, the second electronic device is further configured to: filter particle points in the N frames of third images whose areas are smaller than a first area threshold.

In some embodiments, the modem processor may be an independent device. In other embodiments, the modem processor may be independent of the processor 110 and be set in the same device as the mobile communication module 150 or other functional modules.

[0115] In some embodiments, antenna 1 of electronic device 100 is coupled to mobile communication module 150, and antenna 2 is coupled to wireless communication module 160, so that electronic device 100 can communicate with the network and other devices through wireless communication technology.

[0116] The electronic device 100 implements the display function through a GPU, a display screen 194, and an application processor. The GPU is a microprocessor for image processing, which connects the display screen 194 and the application processor. The GPU is used to perform mathematical and geometric calculations for graphics rendering. The processor 110 may include one or more GPUs that execute program instructions to generate or change display information.

[0117] The display screen 194 is used to display images, videos, etc. The display screen 194 includes a display panel. The display panel can be a liquid crystal display (LCD), or a display panel made of one of the materials such as an organic light-emitting diode (OLED), an active matrix organic light-emitting diode or an active matrix organic light-emitting diode (AMOLED), a flexible light-emitting diode (FLED), miniled, microled, micro-oled or quantum dot light emitting diodes (QLED).

[0118] In an embodiment of the present application, the display screen 194 can also be used to display a ring pattern (such as a Hongmeng ring) including encoding device connection information.

[0119] The electronic device 100 can realize the shooting function through ISP, camera 193, video codec, GPU, display screen 194 and application processor.

[0120] The ISP is used to process the data fed back by the camera 193. The camera 193 is used to capture static images or videos. In the embodiment of the present application, the camera 193 in the old device can be used to scan the display interface of another electronic device to obtain an image including a ring pattern.

[0121] Digital signal processors are used to process digital signals. In addition to processing digital image signals, they can also process other digital signals.

[0122] Video codecs are used to compress or decompress digital video.

[0123] The external memory interface 120 can be used to connect an external memory card, such as a Micro SD card, to expand the storage capacity of the electronic device 100 .

[0124] The internal memory 121 may be used to store computer executable program codes, wherein the executable program codes include instructions. The processor 110 executes various functional applications and data processing of the electronic device 100 by running the instructions stored in the internal memory 121 .

[0125] The electronic device 100 can implement audio functions through the audio module 170, the speaker 170A, the receiver 170B, the microphone 170C, the headphone jack 170D, and the application processor.

[0126] The audio module 170 is used to convert digital audio information into analog audio signal output, and is also used to convert analog audio input into digital audio signals.

[0127] The speaker 170A, also called a "horn", is used to convert audio electrical signals into sound signals.

[0128] The receiver 170B, also called a "handset", is used to convert audio electrical signals into sound signals.

[0129] Microphone 170C, also called "microphone" or "microphone", is used to convert sound signals into electrical signals.

[0130] The earphone jack 170D is used to connect a wired earphone.

[0131] Among them, the sensor module 180 may include a pressure sensor 180A, a gyroscope sensor 180B, an air pressure sensor 180C, an acceleration sensor 180E, a distance sensor 180F, a fingerprint sensor 180H, a touch sensor 180K, a bone conduction sensor 180M, etc.

[0134] Indicator 192 may be an indicator light, which may be used to indicate charging status, power changes, messages, missed calls, notifications, etc.

[0135] The SIM card interface 195 is used to connect a SIM card.

[0136] Figure 2 1 is a software structure diagram of the electronic device 100 of the embodiment of the present application. The layered architecture divides the software into several layers, each layer has a clear role and division of labor. The layers communicate with each other through software interfaces. In some embodiments, the operating system is divided into four layers, from top to bottom, namely, the application layer, the application framework layer, the system library, and the kernel layer. The application layer can include a series of application packages.

[0137] like Figure 2 As shown, the application package may include applications (application, App) such as camera, gallery, calendar, call, map, navigation, WLAN, Bluetooth, music, video, short message, wallet, etc.

[0138] The application framework layer provides an application programming interface (API) and a programming framework for the applications in the application layer. The application framework layer includes some predefined functions.

[0139] like Figure 2 As shown, the application framework layer may include a window manager, a content provider, a view system, a phone manager, a resource manager, a notification manager, and the like.

[0140] The window manager is used to manage window programs. The window manager can obtain the display screen size, determine whether there is a status bar, lock the screen, capture the screen, etc.

[0141] Content providers are used to store and retrieve data and make it accessible to applications. The data may include videos, images, audio, calls made and received, browsing history and bookmarks, phone books, etc.

[0142] The view system includes visual controls, such as controls for displaying text, controls for displaying images, etc. The view system can be used to build applications. A display interface can be composed of one or more views. For example, a display interface including a text notification icon can include a view for displaying text and a view for displaying images.

[0143] The phone manager is used to provide communication functions of the electronic device 100, such as management of call status (including connecting, hanging up, etc.).

[0144] The resource manager provides various resources for applications, such as localized strings, icons, images, layout files, video files, and so on.

[0145] The notification manager enables applications to display notification information in the status bar. It can be used to convey notification-type messages and can disappear automatically after a short stay without user interaction. For example, the notification manager is used to notify download completion, message reminders, etc. The notification manager can also be a notification that appears in the system top status bar in the form of a chart or scroll bar text, such as notifications of applications running in the background, or a notification that appears on the screen in the form of a dialog window. For example, a text message is displayed in the status bar, a prompt sound is emitted, an electronic device vibrates, an indicator light flashes, etc.

[0146] The core library consists of two parts: one part is the function that the Java language needs to call, and the other part is the core library.

[0147] The application layer and the application framework layer run in a virtual machine. The virtual machine executes the Java files of the application layer and the application framework layer as binary files. The virtual machine is used to perform functions such as object life cycle management, stack management, thread management, security and exception management, and garbage collection.

[0148] The system library may include multiple functional modules, such as surface manager, media libraries, 3D graphics processing library (such as OpenGL ES), 2D graphics engine (such as SGL), etc.

[0149] The surface manager is used to manage the display subsystem and provide the fusion of 2D and 3D layers for multiple applications.

[0150] The media library supports playback and recording of a variety of commonly used audio and video formats, as well as static image files, etc. The media library can support a variety of audio and video encoding formats, such as: MPEG4, H.264, MP3, AAC, AMR, JPG, PNG, etc.

[0151] The 3D graphics processing library is used to implement 3D graphics drawing, image rendering, compositing, and layer processing.

[0152] A 2D graphics engine is a drawing engine for 2D drawings.

[0153] The kernel layer is the layer between hardware and software. The kernel layer contains at least display driver, camera driver, audio driver, and sensor driver.

[0154] In some scenarios where information needs to be transmitted between devices, scanning a QR code is usually used for connection pairing between devices, account login, etc. For example, when a user uses a first device to change devices or clone data, data needs to be transferred from the old device to the first device. The old device needs to scan the QR code displayed on the first device for connection pairing. However, the interaction path of scanning a QR code is long and not convenient enough.

[0155] In view of this, the embodiments of the present application provide a method and electronic device for information transmission. In this technical solution, the first device can superimpose the information to be transmitted on a specially designed image. For example, when a device connection is required, the first device can display the specially designed image, and the second device can scan the image to obtain the device connection information therein to achieve the connection between the first device and the second device. When the first device is replaced or data is cloned, the interaction path of the device can be shortened and the sense of technology can be enhanced.

[0156] Before introducing the technical solution of the present application, some professional terms that may be involved in the present application are first introduced as follows.

[0157] Region of interest (ROI): In image processing, the area to be processed is outlined from the image being processed in the form of a box, circle, ellipse, irregular polygon, etc., which is called the region of interest.

[0158] Hue, saturation, value (HSV) color space: A color space that uses hue, saturation, and value to express color, often used in image processing. Hue H represents color, saturation S represents the depth of color, and value V represents the brightness of color.

[0159] Red, green, blue (RGB) color space: A color space that uses the three basic colors of red, green, and blue as the basis, and produces rich and wide-ranging colors by superimposing them to varying degrees. RGB color space is commonly used in video, multimedia, and web design, and the display screens of electronic devices are based on RGB color space.

[0160] Moiré: High-frequency interference stripes that appear on the photosensitive element are high-frequency irregular stripes of color that appear on the image.

[0161] Image binarization: Set the grayscale value of the pixels on the image to 0 or 255. After the image is binarized, the entire image presents a visual effect of only black and white.

[0162] The following will introduce the process of changing the first device and the process of data cloning in the present application in combination with several groups of graphical user interfaces (GUIs). The following description will be made by taking the first device as the electronic device 200 as an example.

[0163] For example, Figure 3 is a schematic diagram of a set of GUIs provided in an embodiment of the present application. Figure 3 (a) to (k) in the figure show the process of a user performing a power-on experience on the electronic device 200 .

[0164] See also Figure 3 In (a), the GUI is a startup display interface 210 of the electronic device 200. The display interface 210 may include multiple language options for the user to select. For example, the user selects Simplified Chinese, or the electronic device 200 selects Simplified Chinese by default.

[0165] The display interface 210 may further include a start function button 211. When the electronic device 200 detects that the user clicks the start function button 211, the display interface 210 may display the following information: Figure 3 GUI shown in (b) in .

[0166] See also Figure 3 In (b), the GUI is a display interface 220 of the electronic device 200 for the user to select a region. The display interface 220 may include a card 221 and a continue function button 222. The card 221 may include multiple countries or regions. For example, the user can select China in the card 221.

[0167] For example, when the electronic device 200 detects that the user clicks the continue function button 222, the following information may be displayed: Figure 3 GUI shown in (c) in FIG.

[0168] See also Figure 3 In (c), the GUI is a display interface 230 of the electronic device 200. The display interface 230 may include text content "Quick Start" and an icon 231 for indicating the electronic device.

[0169] Before the electronic device 200 displays the display interface 230, or when the electronic device 200 displays the display interface 230, the electronic device 200 may broadcast a Bluetooth message to discover a nearby second device. The display interface 230 may display a text content "discovering nearby devices".

[0170] When the user uses the second device to approach the electronic device 200, for example, when the distance between the second device and the electronic device 200 is less than or equal to the preset distance, the second device can display a setting card. When the second device detects that the user clicks the setting function button in the setting card, it can send instruction information to the electronic device 200 via Bluetooth, so that the electronic device 200 can display the following information: Figure 3 GUI shown in (d).

[0171] See also Figure 3 In (d), the GUI is a display interface 240 for connection verification of the electronic device 200. The display interface 240 may include specially designed images, such as dynamic patterns, which can be used for device connection, account login, data transmission, and smooth communication between the electronic device 200 and other electronic devices, and can also be used for screen projection, conference participation, etc. of the electronic device 200.

[0172] Exemplarily, the dynamic pattern may be a ring, such as a Hongmeng ring, or other shapes, such as a rectangle, a circle, an ellipse, etc. The embodiment of the present application takes the dynamic pattern as a ring as an example for explanation, and the ring may be composed of a plurality of white and blue particles, and the plurality of white and blue particles may contain the first information of the electronic device 200. The plurality of white and blue particles may be dynamic or static.

[0173] For example, the first information may include device connection information, verification code, account login information, screen projection information, meeting information, etc. The device connection information may be a connection pairing code, such as a 6-digit number "147258". In other examples, the connection pairing code may also include English letters, or the connection pairing code may also be 4 digits or 8 digits.

[0174] Alternatively, the device connection information may also include other information of the electronic device 200, such as device identification, model, media access control (MAC) address, etc.

[0175] It should be understood that the embodiment of the present application is described by taking the example that the first information may include device connection information, and the device connection information is a connection pairing code.

[0176] It should be understood that the electronic device 200 may use a certain coding method to hide the connection pairing code in the ring pattern.

[0177] In some examples, the electronic device 200 may divide the ring into a plurality of regions, each of which may represent a digit. For example, the electronic device 200 may divide the ring pattern into six regions on average, each of which may include a different number of particles, thereby distinguishing different digits.

[0178] It is understandable that the electronic device 200 can also divide the annular pattern into 9 areas on average, and the 9 areas can include some of the same connection pairing codes. Through this redundant coding method, the success rate of decoding by the peer electronic device can be improved. For example, when the peer electronic device scans the annular pattern, it may only be able to successfully decode part of the annular pattern due to interference such as reflections and moiré. In this case, even if the peer electronic device decodes part of the area, it can still obtain a complete connection pairing code to complete the device connection.

[0179] Alternatively, the electronic device 200 may further divide the annular pattern into a greater number of regions, such as including three or more groups of connection pairing codes, which is not limited in this embodiment of the present application.

[0180] It should be understood that the electronic device 200 may also be encoded in other ways. For example, particles may be displayed at corresponding positions in each area according to a preset order, so that different numbers can be distinguished.

[0181] After the electronic device 200 displays the annular pattern, the user can use the second device to scan the annular pattern, or the user can use the second device to shoot the display interface 240 of the electronic device 200, so that the second device can obtain the annular pattern and decode it to obtain the connection pairing code therein, and the second device uses the connection pairing code to connect and pair to connect the devices. In this way, the second device only needs to shoot or scan the annular pattern displayed by the first device to complete the device connection, thereby improving the efficiency and technological sense of device connection.

[0182] After the devices are connected, the electronic device 200 may display Figure 3 GUI shown in (e) in .

[0183] See also Figure 3 In (e), the GUI is a display interface 250 for the electronic device 200 to verify the lock screen password of the second device. The display interface 250 can be used by the user to input the lock screen password of the second device. In this way, the security of the device connection can be improved. It should be understood that the lock screen password of the second device input by the user will be used as the lock screen password of the electronic device 200. In this way, the user does not need to set the lock screen password in the electronic device 200 separately, which simplifies the user's operation and improves the interaction efficiency between the user and the electronic device 200.

[0184] When the electronic device 200 detects that the user has entered the correct lock screen password, the following information may be displayed: Figure 3 GUI shown in (f) in .

[0185] It should be understood that Figure 3 (e) is an optional solution. In some examples, after the second device scans the annular pattern in the display interface 240 and performs device connection, the electronic device 200 may directly display the following Figure 3 GUI shown in (f) in .

[0186] See also Figure 3 In (f), the GUI is a display interface 255 of the electronic device 200. The display interface 255 may include text content "setting..." and a loading icon.

[0187] It should be understood that when the electronic device 200 displays the display interface 255, the second device can transmit some data to the electronic device 200, such as Huawei account information, Wi-Fi information (such as the name and password of the wireless local area network successfully accessed by the second device), protocol statement or privacy, etc. In this way, the account and wireless network can be quickly migrated without the user having to set it up separately on the electronic device 200, thereby simplifying the user's operation.

[0188] When the electronic device 200 detects that the data transmission is completed, it can display Figure 3GUI shown in (g).

[0189] See also Figure 3 In (g), the GUI is a display interface 260 for data import of the electronic device 200. The display interface 260 may include a display card 261 and a display card 262. The display card 261 may include text content "import directly from the device in use" and the time required for data import (e.g., it takes about 20 minutes), and the display card 262 may include text content "download via cloud backup" and the time required for data import (e.g., it takes about 15 minutes).

[0190] The display interface 260 may further include a function button 263 for not transmitting data. When the user clicks the function button 263, the electronic device 200 will not execute the data import process.

[0191] In other examples, after the electronic device 200 detects that the user clicks on the display card 262, the data of the second device can be downloaded from the cloud server.

[0192] For example, when the electronic device 200 detects that the user clicks on the display card 261, the following information may be displayed: Figure 3 GUI shown in (h).

[0193] See also Figure 3 In (h), the GUI is a display interface 265 for the electronic device 200 to import data options. The display interface 265 may include a display card 2651 for basic data, a display card 2652 for applications and data, a display card 2653 for system settings, and a start import function button 2654.

[0194] The display card 2651 may include the number of basic data items in the second device (e.g., 1526 items) and the size of the memory occupied (e.g., 45.3 GB). The display card 2652 may include the number of applications and data items in the second device (e.g., 2531 items) and the size of the memory occupied (e.g., 35.6 GB). The display card 2653 may include the number of system setting data items (e.g., 531 items) and the size of the memory occupied (e.g., 5 MB).

[0195] For example, when the electronic device 200 detects that the user clicks the function button 2654 to start importing, the following information may be displayed: Figure 3 The GUI shown in (i) in FIG.

[0196] See also Figure 3In (i), the GUI is a display interface 270 for displaying the progress of data importing by the electronic device 200. The display interface 270 may include a progress bar 271 for the progress of data importing and the remaining time of data importing.

[0197] When the electronic device 200 detects that the data import is complete, it may display the following Figure 3 GUI shown in (j) in FIG.

[0198] See also Figure 3 In (j), the GUI may be a display interface 275 of an electronic device. The display interface 275 may include icons of multiple electronic devices and a function button 2751 for immediate experience.

[0199] When the electronic device 200 detects that the user clicks the function button 2751, the following information may be displayed: Figure 3 GUI shown in (k).

[0200] It should be understood that in other examples, after the electronic device 200 detects that the data import is completed, the electronic device 200 may also directly display Figure 3 The GUI shown in (k) is not limited to this embodiment of the present application.

[0201] See also Figure 3 In (k), the GUI is a display interface 280 of the electronic device 200. The display interface 280 may be a display desktop of the electronic device 200, and the display interface 280 may include multiple applications, and the layout of the applications in the display interface 280 is the same as the layout of the display desktop on the second device. At this point, after the user turns on the device, the data migration from the second device to the first device is completed.

[0202] Based on the embodiments of the present application, when using the first device, the user can hide the device connection information in a specially designed image (such as a ring pattern), and the second device scans the specially designed image to obtain the device connection information, and establishes a connection relationship with the first device based on the device connection information, thereby simplifying the device connection process and enhancing the sense of technology of device connection. After the devices are connected, the first device can obtain the data in the second device through convenient operations on the first device, complete data migration, make the new device quickly available, and enhance the user's boot experience of the first device.

[0203] Combination of the above Figure 3 This describes the process of users operating on the first device. Figure 4 This section describes the user's operation process on the second device during the startup experience.

[0204] For example, Figure 4is a schematic diagram of a set of GUIs provided in an embodiment of the present application. Figure 4 (a) to (g) in the figure show the process in which a user operates on the second device to transfer data to the first device.

[0205] See also Figure 4 In (a), the GUI is a display desktop 310 of the electronic device 300. The display desktop 310 may include multiple applications in the electronic device 300.

[0206] It should be understood that the Bluetooth of the electronic device 300 is turned on. When the electronic device 300 detects the Bluetooth broadcast message of the electronic device 200, the following information may be displayed: Figure 4 GUI shown in (b) in .

[0207] Alternatively, when the electronic device 300 detects a Bluetooth broadcast message from the first device (such as the electronic device 200), the first distance from the electronic device 200 can be determined by Bluetooth distance measurement. When the first distance is less than or equal to the preset distance, the electronic device 300 can display a message such as Figure 4 GUI shown in (b) in .

[0208] In other examples, the electronic device 300 displays Figure 4 Before the GUI shown in (b), it can also be in the lock screen display interface or the display interface of other applications, which is not limited in this embodiment of the present application.

[0209] See also Figure 4 In (b), the electronic device 300 may display a display interface 311. The display interface 311 may include an indication icon 3111 of the first device, a model of the first device (such as P60), and a setting function button 3112. The display interface 311 may also include a close function button for closing the display interface 311.

[0210] When the electronic device 300 detects that the user clicks the setting function button 3112, the following information may be displayed: Figure 4 GUI shown in (c) in FIG.

[0211] As described above, after the user clicks the setting function button 3112 , the electronic device 200 displays the display interface 240 which implicitly contains the connection pairing code.

[0212] See also Figure 4 In (c), the electronic device 300 may display a display interface 312. The display interface 312 may include a viewfinder 3121 and text contents such as "Scan to verify" and "Aim the viewfinder at the pattern on the new device".

[0213] Exemplarily, the new device is the first device.

[0214] In other examples, the display interface 312 may also be a viewfinder display interface of a camera or a viewfinder display interface of a camera, which is not limited in the embodiments of the present application.

[0215] It should be understood that the display interface 312 may be a portion covering the display interface 310, that is, the display interface 312 may be displayed in a semi-modal manner. The embodiment of the present application does not limit the specific position of the display interface 312, and the display interface 312 may be located at the bottom of the display interface 310, or at the top of the display interface 310, or at the middle of the display interface 310. The viewfinder 3121 may be located at the center of the display interface 312, or at other positions of the display interface 312, which is not limited in the embodiment of the present application.

[0216] In other examples, the display interface 312 may also be displayed in full screen. Figure 4 (c) in can be Figure 5 Make a substitution. Figure 5 is a schematic diagram of a full-screen display of an electronic device provided in an embodiment of the present application. Figure 5 The electronic device 300 can display the display interface 312 in full screen, and the display interface 312 can refer to the description in the previous text.

[0217] Exemplarily, the user may use the electronic device 300 to scan the display interface 240 of the electronic device 200 , obtain the annular area therein, decode the annular area to obtain the connection pairing code contained therein, and use the connection pairing code to establish a connection relationship with the electronic device 200 .

[0218] It should also be understood that the viewfinder 3121 may also display a breathing effect or a loading effect when framing the annular area, which is not limited in the embodiment of the present application.

[0219] For example, the breathing effect can be understood as the viewfinder 3121 gradually acquiring the annular area from large to small when framing the annular area. And the annular area acquired by the viewfinder 3121 can also display the dynamic change effect of the color stroke. It should be understood that the color stroke can be regular or irregular, and the color stroke can also rotate in a preset direction, or the color stroke can also dynamically change from large to small or from small to large. Alternatively, when acquiring the annular area, the viewfinder 3121 can also display a dynamic icon for indicating the loading content in the acquired annular area. Alternatively, when acquiring the annular area, the viewfinder 3121 can also display the dynamic change effect of the loading process in the acquired annular area.

[0220] For example, after the electronic device 300 detects that the viewfinder has scanned the annular area, the following may be displayed: Figure 4 GUI shown in (d).

[0221] It should be understood that the process of the electronic device decoding the annular area to obtain the connection pairing code will be described below in conjunction with specific embodiments, which will not be described in detail here.

[0222] It should be understood that the display interface 312 may also include a manual verification option. When the electronic device 300 detects that the user clicks on manual verification, it will display a display interface for entering a 6-digit connection pairing code. At this time, the electronic device 200 will display a display interface including a 6-digit connection pairing code. After the user enters the connection pairing code, the electronic device 300 and the electronic device 200 can establish a connection relationship after mutual verification. At this time, the electronic device 300 can display the following Figure 4 GUI shown in (d).

[0223] See also Figure 4 In (d), the electronic device 300 may display a display interface 313. The display interface 313 may include an icon indicating that two devices are connecting and text content “Connecting”.

[0224] After the electronic device 300 is connected to the electronic device 200, the electronic device 300 may display Figure 4 GUI shown in (e) in .

[0225] See also Figure 4 In (e), the electronic device 300 may display a display interface 314. The display interface 314 may include an icon of the connection between the two devices and text content "operate on the new device".

[0226] Exemplarily, the new device is the first device.

[0227] For example, at this time, the electronic device 200 may display the display interface 250 to improve the security of the device connection. After the user selects data on the electronic device 200 to perform data operations, for example, when the electronic device 200 detects that the user clicks the function button 2654 to start importing, the electronic device 300 may display the following Figure 4 GUI shown in (f) in .

[0228] See also Figure 4 In (f), the electronic device 300 may display a display interface 315. The display interface 315 may display a guide for migrating data from one device to another device and a text content “data is being imported”.

[0229] When the electronic device 300 detects that the data import is complete, it may display the following Figure 4 GUI shown in (g).

[0230] See also Figure 4 In (g), the electronic device 300 may display a display interface 316. The display interface 316 is used to prompt the user that the data import is complete.

[0231] Based on the embodiment of the present application, when a user uses a first device, he can use a second device to scan the circular pattern displayed on the first device to obtain the connection pairing code therein, and establish a connection relationship with the first device based on the connection pairing code. Afterwards, when the second device transmits data to the first device, the second device can also display operation instructions and the progress of data transmission, so that the user can obtain the data transmission status.

[0232] In some cases, when cloning data on an electronic device that is not turned on for the first time, the second device can also establish a device connection by scanning a ring pattern. Figure 6 Introduce the technical solution.

[0233] For example, Figure 6 is a schematic diagram of another set of GUIs provided in an embodiment of the present application. Figure 6 (a) to (k) in FIG. 4 show the process in which a user operates on the electronic device 400 to perform data cloning.

[0234] See also Figure 6 In (a), the GUI may be a display desktop 410 of the electronic device 400. The display desktop 410 may include multiple applications. For example, the multiple applications may include a first application, and the first application may be an application for data cloning, such as mobile phone cloning.

[0235] For example, when the electronic device 400 detects that the user clicks on the first application, the following information may be displayed: Figure 6 GUI shown in (b) in .

[0236] See also Figure 6 In (b), the GUI is a display interface 420 of the first application. The display interface 420 may include a display card 421 and a display card 422. The display card 421 may include text content "This is the second device" and an icon. The display card 422 may include text content "This is the first device" and an icon.

[0237] When the electronic device 400 detects that the user clicks the display card 422, the following may be displayed: Figure 6 GUI shown in (c) in FIG.

[0238] See also Figure 6In (c), the electronic device 400 may display a display interface 430. The display interface 430 may include multiple types of second devices, such as Huawei, Android, etc. The display interface 430 may be used for the user to select the type of the second device.

[0239] For example, when the electronic device 400 detects that the user selects the type of operation "Huawei", the following information may be displayed: Figure 6 GUI shown in (d).

[0240] It can be understood that the electronic device 400 can broadcast a Bluetooth message. When the second device (such as the electronic device 300) detects the Bluetooth message and the distance between the electronic device 300 and the electronic device 400 is less than or equal to the preset distance, the electronic device 300 can display the display interface 311. When the user clicks the setting function button 3112, the electronic device 300 can send an indication message to the electronic device 400. At this time, the electronic device 400 can display the following information: Figure 6 GUI shown in (d).

[0241] In other examples, after the electronic device 400 detects that the user selects the type "Huawei", it can also directly display the following Figure 6 GUI shown in (e) in .

[0242] See also Figure 6 In (d), the GUI is a display interface 450 for connection verification of the electronic device 400. The display interface 450 may include a specially designed image, such as a dynamic pattern, and the specially designed image may be used to connect the electronic device 400 to other electronic devices.

[0243] It should be understood that Figure 6 For details of (d) in Figure 3 The relevant description in (d) in .

[0244] It should also be understood that Figure 6 For (e) to (k) in Figure 3 For the sake of brevity, the relevant descriptions of (e) to (k) in FIG. 1 are not repeated here.

[0245] Based on the embodiments of the present application, when performing data cloning, the first device can hide the device connection information in a specially designed image (such as a ring pattern), and the second device scans the specially designed image to obtain the device connection information, and establishes a connection relationship with the first device based on the device connection information, thereby simplifying the device connection process and enhancing the sense of technology of device connection. After the devices are connected, the first device can obtain the data in the second device through convenient operations on the first device to complete data migration.

[0246] In other examples, device A can also encode account information into a specially designed image (such as a ring pattern). When account login is required, device A can display the ring pattern, and device B can scan and parse the ring pattern displayed by device A to implement the account login function. It should be understood that the above solution is also applicable to scenarios such as device connection establishment, data transmission, account login, screen projection, free connection, video conference, etc.

[0247] Combination of the above Figure 3-6 The GUI introduces the process of quickly making new machines available and cloning data. Figure 7-11 The process of an electronic device acquiring and decoding a ring pattern in an embodiment of the present application is introduced.

[0248] It should be understood that the present application embodiment is described by taking the first device encoding the device connection information in a ring pattern as an example. Figure 7-8 The process of the second device acquiring the ring pattern is introduced.

[0249] For example, Figure 7 An embodiment of the present application provides a process for obtaining a ring pattern.

[0250] When connecting devices, the first device encodes the device connection information in a ring pattern and displays a display interface containing the ring pattern. After the second device uses a camera to scan the display interface containing the ring pattern on the first device, it first recognizes the ring pattern from the image. Figure 7 As shown, the process of the second device acquiring the annular pattern may include steps 1 to 5.

[0251] Step 1: The second device converts the RGB image containing the ring pattern into an HSV image.

[0252] Exemplarily, the image containing the annular pattern acquired by the second device is generally an RGB image, and the second device converts the RGB into an HSV image. In the HSV image, there is a corresponding value distribution in the H domain, the S domain, and the V domain.

[0253] It should be understood that the second device can convert the RGB image containing the ring pattern into an HSV image using the following formula.

[0254]

[0255] v=max

[0256] Among them, (r, g, b) represents the red, green, and blue coordinates of a color, respectively, and their values ​​are real numbers between 0 and 1. max is the maximum value among r, g, and b. min is the minimum value among r, g, and b.

[0257] Step 2: The second device performs threshold filtering in the H domain, S domain, and V domain respectively.

[0258] Exemplarily, the H domain can be measured by angle, ranging from 0 to 360 degrees. In the embodiment of the present application, the second device can retain the components in the H domain of the image whose angles are greater than the first angle and less than or equal to the second angle, and filter out the remaining angles.

[0259] In some examples, the annular pattern is mainly blue, the first angle may be 210 degrees, and the second angle may be 270 degrees. The second device can retain the blue component in the image and filter out the other color components by this filtering method. In this way, even if there is reflection in the image containing the annular pattern obtained by the second device, the reflection can be filtered out to reduce the interference caused by the reflection.

[0260] In some other examples, the annular pattern is mainly green, the first angle may be 90 degrees, and the second angle may be 150 degrees. The second device can retain the green component in the image and filter out the other color components through this filtering method.

[0261] It should be understood that the first angle and the second angle can be set by the developer based on experience, and can also be determined by the second device based on the numerical distribution of the H domain. The embodiment of the present application does not limit the specific method of obtaining the first angle and the second angle.

[0262] Similarly, the S domain represents saturation, which represents the degree to which the color is close to the spectral color, and can be expressed by 0 to 1 (or 100%), where 0 represents the lowest saturation (pure white) and 1 represents the highest saturation, which is closest to the spectral color of the color.

[0263] The V domain represents brightness, which represents the lightness or darkness of a color, and can be expressed from 0 to 1 (or 100%), where 0 represents the lowest brightness (pure black) and 1 represents the highest brightness, the brightest color.

[0264] By setting the S threshold and V threshold, you can filter out the darker colors in the image.

[0265] For example, the second device may retain components in the S domain whose values ​​are greater than the first saturation threshold and less than or equal to the second saturation threshold, and retain components in the V domain whose values ​​are greater than the first brightness threshold.

[0266] It should be understood that the embodiments of the present application do not limit the specific values ​​of the first saturation threshold, the second saturation threshold, and the first brightness threshold. For example, the first saturation threshold is 0.3 or 0.35, the second saturation threshold is 0.9 or 0.85, and the first brightness threshold is 0.5 or 0.6.

[0267] In other examples, the second device may also perform threshold filtering in the H domain alone in step 2, and not perform threshold filtering in the S domain and the V domain.

[0268] Step 3: The second device performs binarization processing on the image.

[0269] After threshold filtering in step 2, the second device can perform binarization processing on the image. For example, the second device can set a grayscale threshold in the S domain and the V domain, and the value of the part greater than the grayscale threshold is 1 (or the grayscale value is 255), that is, white, and the value of the part less than or equal to the threshold is 0 (or the grayscale value is 0), that is, black.

[0270] Exemplarily, in the S domain, the second device may set a first grayscale threshold, and the value of a portion greater than the first grayscale threshold is 1, indicating white, and the value of a portion less than or equal to the first grayscale threshold is 0, indicating black.

[0271] In the V domain, the second device may set a second grayscale threshold, and the value of the portion greater than the second grayscale threshold is 1, indicating white, and the value of the portion less than or equal to the second grayscale threshold is 0, indicating black.

[0272] In this way, the second device can obtain a binarized image A, which includes only black or white.

[0273] Step 4: The second device performs a closing operation on the binarized image A.

[0274] For example, the second device may first dilate image A and then erode it, so that the discrete points form a connected domain. Figure 7 , after the closing operation is performed on image A, the discrete white points in image A form a connected domain.

[0275] For example, dilating image A can be understood as using a first rectangle (with a width of m pixels and a height of n pixels), placing pixel X at the center of the first rectangle for each pixel X in image A, traversing all other pixels covered by the first rectangle, and modifying the value of pixel X to the maximum value of the pixels covered by the first rectangle.

[0276] The erosion of image A can be understood as using a first rectangle (with a width of m pixels and a height of n pixels), for each pixel X in image A, placing pixel X at the center of the first rectangle, traversing all other pixels covered by the first rectangle, and modifying the value of pixel X to the smallest value among the pixels covered by the first rectangle.

[0277] In other examples, the second device may also use other methods to perform a closing operation on image A, which is not limited in the embodiments of the present application.

[0278] Step 5: The second device extracts a region of interest ROI, which is the area where the annular pattern is located.

[0279] Exemplarily, the second device may perform ellipse fitting on the connected domain to extract a ROI containing a ring pattern.

[0280] It should be understood that the embodiment of the present application does not limit the fitting method. In other examples, the second device can also adopt rectangular fitting and the like.

[0281] Based on the embodiment of the present application, the second device can successfully acquire the annular pattern displayed in the first device.

[0282] In some cases, due to severe reflection or partial obstruction of the ring pattern, the second device will not be able to form a connected domain of discrete points when performing a closing operation on the binarized image, which may cause the second device to be unable to recognize the complete ring pattern, which will cause the second device to be unable to successfully decode and cause the device connection to fail. Therefore, for this situation, the embodiment of the present application can use particle point clustering to obtain the complete ring pattern. Figure 8 Introduce the technical solution.

[0283] For example, Figure 8 Another process for obtaining a ring pattern is provided in an embodiment of the present application. Figure 8 As shown, the process of the electronic device acquiring the ring pattern may include steps 1 to 5.

[0284] Step 1: The second device converts the image containing the ring pattern into an HSV image.

[0285] Step 2: The second device performs threshold filtering in the H domain, S domain, and V domain respectively.

[0286] Step 3: The second device performs binarization processing on the image.

[0287] It should be understood that the above steps 1 to 3 can refer to the above Figure 7 For the sake of brevity, the relevant descriptions of steps 1 to 3 in are not repeated here.

[0288] Step 4: The second device performs particle point filtering on the binarized image A.

[0289] The second device obtains image A after binarizing the image, and the image A includes black and white colors, wherein white particle points are distributed in a discrete manner in image A. Since there may be some interfering points among these particle points, for example, some particle points with a larger area may be interfering points. Therefore, the second device may filter the particle points included in image A.

[0290] Exemplarily, the second device may set an area threshold for particle points, retaining particle points whose areas are less than or equal to the first threshold m1, or retaining particle points whose areas are less than or equal to the first threshold m1 and greater than the second threshold m2, and filtering out the remaining particle points.

[0291] In this way, the second device can filter out some interfering particle points in the image, which helps to improve the possibility of subsequent decoding.

[0292] It should be understood that step 4 is an optional step.

[0293] In other examples, before step 4, the second device may first perform edge detection on the binarized image A to extract the contour in image A to determine the area in image A where the display screen of the first device is located.

[0294] Step 5: The second device extracts ROI, which is the area where the annular pattern is located.

[0295] Exemplarily, the second device may use a ring clustering algorithm to cluster the particle points to obtain multiple rings. Afterwards, the second device may select a ring from the multiple rings whose aspect ratio is approximately equal to 1 and whose ratio of the center of the ring to the particle point density of the ring area is greater than a third density threshold, and use the ring as the extracted ROI.

[0296] Alternatively, the second device may also select a circular ring from multiple circular rings whose aspect ratio is approximately equal to 1 and whose particle point density in the circular ring area is greater than a fourth density threshold, and use the circular ring as the extracted ROI.

[0297] It should be understood that the ring clustering algorithm may be, for example, a spectral clustering algorithm, a clustering algorithm based on Euclidean distance such as a K-means algorithm, or the like.

[0298] Continue to see Figure 8 , the ROI finally extracted by the second device may include the complete annular pattern. In other examples, if the annular pattern is partially blocked, the ROI finally obtained by the second device may include part of the annular pattern, such as 60% or 75% of the entire annular pattern. However, due to the partial redundancy of the first device during encoding, even though the second device obtains part of the entire annular pattern, it may still be successfully decoded and obtain the device connection information.

[0299] After the second device successfully extracts the ROI including the annular pattern, the second device may process the ROI to obtain the device connection information encoded therein. Fig. 9 Introduce the technical solution.

[0300] For example, Fig. 9 FIG. 1 is a schematic diagram of obtaining a connection pairing code provided in an embodiment of the present application. Fig. 9 As shown, the process of the second device acquiring the device connection information may include steps 1 to 7.

[0301] The second device can Figure 8 The ROI is extracted from continuous or discontinuous multiple frame images in the manner described above to obtain multiple frame images including ring patterns.

[0302] Step 1: The second device performs intra-frame difference processing on img1, img2 to imgn, respectively, to obtain grayscale images img1-1, img2-1 and imgn-1, respectively. n is greater than or equal to 2.

[0303] The intra-frame difference processing performed by the second device on img1 is taken as an example to illustrate the process of intra-frame difference.

[0304] img1 has three channels of RGB. The second device first decomposes the three channels of RGB on img1 to obtain an R channel image, a G channel image, and a B channel image, and the corresponding values ​​are counted as R1, G1, and B1, respectively.

[0305] In one example, the second device may use the formula img1-1=|(B1-R1)+(B1-G1)| to perform intra-frame difference processing to obtain a grayscale image img1-1.

[0306] In another example, the second device may perform intra-frame difference processing using the formula img1-1=|(G1-R1)+(G1-B1)| to obtain a grayscale image img1-1.

[0307] Similarly, the second device performs intra-frame difference processing on img2 to imgn respectively to obtain grayscale images img2-1 to imgn-1 respectively.

[0308] In this way, by performing intra-frame difference processing on img1, img2 to imgn respectively, the characteristic particle points included in the obtained grayscale image can be made more obvious, which is beneficial for the second device to obtain the connection pairing code encoded therein.

[0309] Step 2: The second device performs inter-frame difference processing on img1-1, img2-1 to imgn-1 respectively to obtain differential images img1-2, img2-2 to imgn-2.

[0310] Exemplarily, the second device may perform pairwise differential processing on img1-1, img2-1 to imgn-1 respectively.

[0311] For example, take n as 3. The second device may perform a differential operation on img1-1 and img2-1 as image img1-2; the second device may perform a differential operation on img2-1 and img3-1 as image img2-2; the second device may perform a differential operation on img3-1 and img1-1 as image img3-2.

[0312] It should be understood that the differential operation can be understood as a process of subtracting the grayscale values ​​of corresponding pixels of two frames of images and taking the absolute value.

[0313] It should be understood that the embodiment of the present application does not limit the specific execution order of step 1 and step 2. In some examples, the second device may also execute step 2 first and then execute step 1.

[0314] It should be understood that between step 1 and step 2, the second device may also perform multi-frame alignment processing on the grayscale images img1-1, img2-1 to imgn-1.

[0315] Exemplarily, the description is made by taking n as 3. The second device may align img1-1 and img1-3 based on the intermediate image img2-1.

[0316] For example, the second device may align img1-1 and img1-3 by using affine transformation or feature point alignment, thereby reducing the effect of misalignment caused by jitter when the second device acquires the image of the ROI.

[0317] In other examples, the second device may also perform alignment processing on multiple frames of images based on img1-1 or img1-3.

[0318] It should be understood that the second device can also use other existing multi-frame alignment methods to align the above-mentioned images, and the embodiments of the present application are not limited to this.

[0319] Step 3: The second device determines the degree of moiré in img1-2, img2-2 to imgn-2.

[0320] Exemplarily, taking img1-2 as an example, the second device performs binarization processing on the image img1-2 to obtain the binarized image img1-2, and determines the degree of moiré according to the density of particle points in the image img1-2.

[0321] For example, the second device may classify the moiré into three levels: none, low, and high according to the density of the particle points. Alternatively, the second device may classify the moiré levels according to other indicators, which are not limited in this application.

[0322] For example, if the second device determines that the density of particle points is less than the first density threshold, it can be determined that there is no moiré. If the second device determines that the density of particle points is greater than the first density threshold or less than or equal to the second density threshold, and the second density threshold is twice the first density threshold, it can be determined that the degree of moiré is low. If the second device determines that the density of particle points is greater than the second density threshold, it can be determined that the degree of moiré is high.

[0323] It should be understood that the second device may further divide the moiré pattern into none or two degrees, or the second device may further divide the moiré pattern into more degrees, which is not limited in the present application.

[0324] In this way, the second device can determine the severity of the moiré in the image, which helps to remove the moiré later.

[0325] Step 4: The second device sets the binarization threshold according to the degree of moiré in img1-2, img2-2 to imgn-2, respectively, to obtain binary images img1-3, img2-3 to imgn-3.

[0326] Exemplarily, taking img1-2 as an example, if there is no moiré in img1-2, the second device can set a first grayscale threshold to filter out the grayscale value of the pixel in the grayscale image that is less than the first grayscale threshold. If there is moiré in img1-2, and the degree of the moiré is low, the second device can set a second grayscale threshold to filter out the grayscale value of the pixel in the grayscale image that is less than the second grayscale threshold. If there is moiré in img1-2, and the degree of the moiré is high, the second device can set a third grayscale threshold w3 to filter out the grayscale value of the pixel in the grayscale image that is less than the third grayscale threshold.

[0327] The higher the degree of moiré, the larger the corresponding grayscale threshold. Correspondingly, the first grayscale threshold is smaller than the second grayscale threshold, and the second grayscale threshold is smaller than the third grayscale threshold.

[0328] It should be understood that the first grayscale threshold, the second grayscale threshold, and the third grayscale threshold may be set by a developer, or may be determined by the second device according to the distribution of the moiré pattern, and the embodiments of the present application are not limited thereto.

[0329] In this way, the second device sets a corresponding filtering threshold according to the degree of the moiré pattern, so that the moiré pattern can be filtered out as much as possible, thereby reducing the influence of the moiré pattern on the recognition result.

[0330] Step 5: The second device performs an OR operation on the binary images img1-3, img2-3 to imgn-3 to obtain image img-a.

[0331] The second device can perform an OR operation on the multiple frames of binary images so that the obtained img-a can include more characteristic particle points, thereby improving the probability of the second device performing decoding.

[0332] It should be understood that step 5 is an optional step, and in some examples, step 5 may not be performed.

[0333] Step 6: The second device performs threshold filtering on the area of ​​the particle points in the image img-a to obtain the image img-f.

[0334] For example, the second device may determine the area of ​​all particle points in the image img-a and sort them in descending order of area, and then the second device may set a first area threshold to filter the particle points. For example, if the first area threshold is 70%, the second device may retain the first 70% of the particle points.

[0335] It should be understood that the first area threshold may also be other values, such as 65% or 75%, etc. The embodiment of the present application does not limit the specific value of the first area threshold.

[0336] In other examples, the second device may determine the area of ​​all particle points in the image img-a and set a second area threshold to filter the particle points. For example, the particle points in img-a whose area is less than or equal to the second area threshold are filtered out, and the particle points whose area is greater than the second area threshold are retained.

[0337] Step 7: The second device parses the image img-f to obtain device connection information.

[0338] It should be understood that the specific execution order of the above steps 1-7 is not limited in the embodiment of the present application. In other examples, steps 3-6 in the steps 1-7 are optional steps.

[0339] The device connection information may be a connection pairing code. Alternatively, the device connection information may also include a device identification, a MAC address, etc. of the first device. In the embodiment of the present application, the device connection information is described as a 6-digit connection pairing code.

[0340] In one example, the second device may evenly divide the annular region where the particle points in the image img-f are located into a plurality of regions, and determine a corresponding number according to the number of particle points in each region.

[0341] For example, Fig.10 is a schematic diagram of an annular region provided in an embodiment of the present application. Fig.10, the second device can divide the annular area into n areas in order, namely area 1, area 2, area 3,..., area n, and decode the n areas respectively to obtain corresponding numbers. It should be understood that the embodiment of the present application does not limit the specific value of n. For example, n is 6, and area 1 to area 6 can encode a set of connection pairing codes. Or, n is 9, in this case, the second device can redundantly decode part of the connection pairing codes, and accordingly, the first device also redundantly encodes part of the connection pairing codes. Through this redundant encoding method, when there are some areas in area 1 to area n that cannot be recognized by the second device, the second device can still successfully obtain the connection pairing code, thereby increasing the possibility of successful decoding by the second device.

[0342] It should be understood that the first device can cyclically encode the n areas. For example, when n is 18, the first device can cyclically encode the 6-digit connection pairing code and can encode 3 groups of 6-digit connection pairing codes. Through this redundant encoding method, the possibility of successful decoding by the second device can be increased.

[0343] In other examples, the first device may further set a check digit in the first area of ​​each group of connection pairing codes or in an area before an area of ​​each group of connection pairing codes, so that the second device can determine the order of the digits of the connection pairing codes.

[0344] The second device can determine its coded number according to the number of particle points in each area. For example, for area 1, if there is one particle point therein, it can be determined that its coded number is 1. For area 2, if there are 4 particle points therein, it can be determined that its coded number is 4.

[0345] The second device can obtain the final 6-digit connection pairing code, such as 147258, through the above decoding method.

[0346] It should be understood that the second device may also divide the annular area into more areas in sequence, such as 15 areas, 18 areas or 24 areas, etc., so as to increase the possibility of successful decoding by the second device.

[0347] In another example, the second device may evenly divide the annular region where the particle points in the image img-f are located into a plurality of regions, such as 6 regions, and determine the corresponding number according to the distribution of the particle points in each region.

[0348] For example, for area 1, the second device may evenly divide area 1 into 10 grids (numbered 0 to 9). If there is a particle point in area 1, then the number represented by the area can be determined by the grid in which the particle point is located. For example, if the particle point is located in the first grid, it can be determined that area 1 corresponds to number 1.

[0349] If there are multiple particle points in the area 1, the number of the grid containing the largest number of particle points is determined as the number obtained by decoding. For example, if the second grid contains the largest number of particle points, it can be determined that the area 1 corresponds to number 2.

[0350] In some cases, in order to increase the probability that the second device successfully decodes and obtains the correct connection pairing code, the second device may also combine multiple decoding results to determine the final connection pairing code.

[0351] For example, Fig.11 Schematic diagram of determining a connection pairing code by combining multiple decoding results provided by an embodiment of the present application. Fig.11 As shown, through Fig. 9 and Fig.10 In the decoding method, the second device decodes the three frames of images, image 1, image 2, and image 3, to obtain the connection pairing code 1 "147258", decodes the three frames of images, image 2, image 3, and image 4, to obtain the connection pairing code 2 "147256", and decodes the three frames of images, image 3, image 4, and image 5, to obtain the connection pairing code 3 "147258", then the second device can finally determine that the obtained connection pairing code is "147258". In this way, even if the last digit of the connection pairing code 2 decoded by the second device is wrong, the second device can determine the final correct connection pairing code by combining the connection pairing code 1 and the connection pairing code 3.

[0352] It should be understood that Fig.11 Only three results obtained by the second device are used as an example for illustration. In other examples, the second device may also obtain more results to improve the correctness of the connection pairing code finally determined.

[0353] Based on the embodiment of the present application, the second device can determine the final connection pairing code based on the results of multiple decodings, thereby avoiding the phenomenon that the device connection fails due to incorrect decoding once.

[0354] It should be understood that after the second device obtains the device connection information, it can use the device connection information to establish a connection relationship with the first device.

[0355] Fig.12 is a schematic interactive diagram of a method for information transmission provided by an embodiment of the present application. Fig.12 As shown, the method 600 may be applied to a first electronic device and a second electronic device, and the method 600 may at least include steps 610 to 650.

[0356] It should be understood that the first electronic device may be the first device mentioned above, and the second electronic device may be the second device mentioned above.

[0357] 610: The first electronic device sends a first message, and correspondingly, the second electronic device receives the first message.

[0358] Exemplarily, the first message may be a Bluetooth broadcast message. The first message may also be other wireless messages, which is not limited in the embodiment of the present application.

[0359] The first message may be used to discover devices around the first electronic device.

[0360] 620. The second electronic device sends first indication information to the first electronic device according to the first message.

[0361] The first indication information may be used to indicate that there are devices around the first electronic device. Alternatively, the first indication information may be confirmation information after the first message is scanned.

[0362] In some examples, the second electronic device also displays a target display interface based on the first message, which target display interface may include relevant information of the first electronic device. In response to the user's operation in the target display interface, the second electronic device may send the above-mentioned first indication information to the first electronic device.

[0363] 630. The first electronic device displays a first image according to the first indication information, where the first image includes a first part and a second part.

[0364] It should be understood that the first part may be the background of the first image, and the second part may be the part of the first image encoding the first information. Exemplarily, the second part may be superimposed on the first part.

[0365] For example, see Figure 3 In (d), the first image may be an image corresponding to the display interface 240, the second part may be an information point in the annular pattern therein, and the first part may be the background part outside the information point.

[0366] It should be understood that when the electronic device displays N frames of the first image, positions of the second parts in two adjacent frames of the N frames of the first image are the same, and N is greater than or equal to 2.

[0367] In other examples, the colors of the second parts of two adjacent frames of images in N frames may be different. Or, the colors of the second parts of any three consecutive frames of images in N frames may be different, which is not limited in the embodiment of the present application.

[0368] In other examples, the second parts of two adjacent frames of images in N frames of images can encode the same information or different information. When encoding different information, the first electronic device can divide the information to be encoded into multiple parts and encode them in the second parts of images of different frames respectively. Alternatively, multiple consecutive frames of images in N frames of images can encode different information, and multiple groups of information can be encoded in the N frames of images, which is not limited in the embodiments of the present application.

[0369] When the second parts of multiple frames of first images encode different information, the first electronic device may split the information to be encoded into multiple parts, each frame of the image may encode a part of the information, and multiple frames of the image may be combined to encode the complete information.

[0370] For example, taking three frames of images as an example, the first electronic device may divide the information to be encoded into information A, information B and information C, and encode them respectively in three consecutive frames of images.

[0371] In other examples, the first parts in two adjacent frames of the N frames of the first image may be the same or different. For example, some particle points included in the first part may move or change color.

[0372] In some examples, the first part or the second part may have an animation effect. For example, a plurality of particle points forming a ring pattern may gradually converge into a ring with a flow effect.

[0373] 640. The second electronic device acquires N frames of first images, each of the N frames of first images includes a first part and a second part, and positions of the second parts of two adjacent frames of the N frames of images are the same, wherein N is greater than or equal to 2.

The second electronic device may decode img-f to obtain the connection pairing code 147258. The second part is encoded with the first information that the second electronic device needs to transmit, and the second electronic device decodes the second part of the acquired image to determine the first information therein.

[0377] Exemplarily, when the second part of each of the N frames of first images encodes the same first information, the second electronic device may decode multiple consecutive frames (such as 2 or 3 frames) and determine the first information encoded therein according to the decoding result of each frame. Alternatively, the second electronic device may also select one of the frames to decode to determine the first information encoded therein.

[0378] Exemplarily, when the second part of each of the N frames of the first image encodes different information, the second electronic device may decode the second parts of a plurality of consecutive frames of the first image and combine the decoding results to determine the final first information.

[0379] Optionally, after decoding and obtaining the first information, the second electronic device may perform the first operation according to the first information.

[0380] Exemplarily, the first information may be device connection information. In this case, the first operation is to send a device connection request. When the second electronic device needs to establish a connection relationship with the first electronic device, the second electronic device may send a device connection request to the first electronic device based on the device connection information and establish a connection relationship with the first electronic device.

[0381] Exemplarily, the first information may be account login information. In this case, the first operation may be an operation of logging into the account.

[0382] Exemplarily, the first information may also be first data. In this case, the first operation may be an operation of acquiring the first data.

[0383] Exemplarily, the first information may also be a conference link. In this case, the first operation is an operation of joining the conference.

[0384] Exemplarily, the first information may also be a website. In this case, the first operation is an operation of accessing the website.

[0385] Exemplarily, the first information may also be screen projection information. In this case, the first operation is a screen projection operation.

[0386] It should be understood that the first information may also include other content, which is not limited in the embodiment of the present application.

[0387] Based on the system provided in the embodiment of the present application, the first electronic device can encode the first information to be transmitted in the second part of the first image, and the second electronic device can obtain N frames of the first image and decode the first information based on the second part.

[0388] For example, when connecting devices, the second electronic device can scan or take a picture of the image displayed by the first electronic device to obtain the device connection information (connection pairing code), so that the device connection can be quickly established. When replacing a new device or cloning data, the device interaction path can be shortened and the sense of technology can be enhanced.

[0389] In some implementations, before the second electronic device decodes the first information according to the second part, the second electronic device is further configured to: perform color space conversion on the N frames of the first image to obtain the N frames of the second image.

[0390] Based on the embodiment of the present application, the second electronic device can reduce the impact of reflections in the first image by performing color space conversion on the first image.

[0391] For example, the first image is converted from the RGB color space to the HSV color space, or the hue, saturation, brightness HSI color space, etc.

[0392] In some embodiments, the second electronic device is specifically configured to:

[0393] Convert the first image of frame N from the red, green and blue RGB color space to the hue, saturation and brightness HSV color space;

[0394] Filtering the hue H domain of each frame of the N frames of first images to obtain N frames of second images, wherein the angle value corresponding to the hue H domain included in the second images is greater than a first preset value and less than a second preset value;

[0395] Binarizing the N frames of the second image to obtain the N frames of the third image;

[0396] The second part is determined according to N frames of third images.

[0397] For example, see Figure 7 , taking one frame of the image as an example for explanation. The second image may be an image containing a blue component obtained by filtering the hue H domain. The third image may be an image obtained by binarizing the second image.

[0398] The second part may be an annular area, or may be part of the information points included in the annular area.

[0399] It should be understood that the embodiment of the present application does not limit the specific values ​​of the first preset value and the second preset value.

[0400] Based on the embodiments of the present application, through the conversion of the color space and the corresponding threshold filtering, the reflection phenomenon in the first image can be filtered out, the interference of the reflection on the second electronic device obtaining the second part can be reduced, and the possibility of successful decoding can be improved.

[0401] In some embodiments, the second electronic device is specifically configured to:

[0402] Perform a closing operation on the N frames of the third image; determine the second part according to the result of the closing operation; or,

[0403] Perform cluster analysis on particle points in the N-frame third image; and determine the second part according to the result of the cluster analysis.

[0404] For example, see Figure 8 For some scenes with severe reflection or missing annular areas, the second electronic device can perform particle point clustering analysis on the third image obtained by binarization processing to determine the annular area. The second part can be the annular area or part of the information points included in the annular area.

[0405] Based on the embodiment of the present application, the second part is determined by a closed operation, which can reduce the interference of reflection on the second electronic device obtaining the second part, and improve the possibility of successful decoding. In addition, in the case where the second part is more blocked or severely reflected, the second part can still be successfully obtained through the results of cluster analysis, which improves the possibility of the electronic device successfully decoding the second part later.

[0406] In some embodiments, before the second electronic device performs cluster analysis on the N frames of third images, the second electronic device is further configured to: filter particle points in the N frames of third images whose areas are smaller than a first area threshold.

[0407] For example, see Figure 8 In step 4, particle points in the third image whose area is smaller than the first area threshold may be filtered.

[0408] Based on the embodiment of the present application, particle points with a smaller area in the third image can be filtered out, thereby reducing the interference of the particle points with a smaller area on the acquisition of the second part.

[0409] In some embodiments, the second electronic device is specifically configured to:

[0418] Based on the embodiment of the present application, the second electronic device can decode based on the second part included in the N frames of image to successfully obtain the first information encoded therein.

[0420] Filtering particle points whose areas in the first target image are smaller than a second area threshold value to obtain a second target image;

[0421] The first information is decoded according to the second target image.

[0422] For example, see Fig. 9 , the second target image can be img-f.

[0423] Based on the embodiment of the present application, by filtering the particle points in the first target image, the particle points with smaller areas in the first target image can be filtered out, thereby reducing the interference of the particle points with smaller areas on the decoding results.

[0429] It should be understood that the degree of the moiré determined by the second electronic device can refer to the relevant description of the degree of the moiré determined by the second device in the above text, and the embodiment of the present application is not limited thereto.

[0430] Based on the embodiment of the present application, the second electronic device can also determine the degree of moiré in the image and set a filtering threshold according to the degree of moiré, thereby reducing the interference caused by the moiré and helping to increase the probability of successful decoding.
