[0026] like Figure 1 As shown, this application embodiment provides an image display method, executed by a first device, which may specifically include the following steps S102 to S108:
[0027] S102: Receive the first input to the lightweight image.
[0028] The image display method proposed in this application is executed by a first device, which may be an electronic device such as a smartphone, tablet computer, or laptop computer, and is not specifically limited to these devices.
[0029] The first device stores lightweight images, which include, but are not limited to, thumbnails, preview images, low-resolution images, and indexed images, without any specific restrictions.
[0030] Optionally, the second device may be different from the first device. Specifically, the second device may be an electronic device such as a smartphone, tablet, or laptop computer, without any specific limitations.
[0031] Optionally, the second device stores a high-resolution image corresponding to the lightweight image. The high-resolution image corresponding to the lightweight image includes the original image of the lightweight image. The high-resolution image corresponding to the lightweight image may also include adapted images of the original image of the lightweight image at different resolutions, such as adapted images of the original image at the screen resolution of the first device.
[0032] Optionally, the first device stores lightweight images in a first database, and the second device stores high-resolution images in a second database.
[0033] In practical applications, the first database maintains a real-time mapping relationship between the stored lightweight images and the high-resolution images in the second database, while the second database also maintains a real-time mapping relationship between the stored high-resolution images and the lightweight images in the first database. Specifically, the changes in the stored images are synchronized between the first and second databases in real time to ensure consistency in the mapping link between the two databases, thereby guaranteeing the accuracy of subsequent image display.
[0034] Optionally, the first input mentioned above is a user's touch input to the lightweight image. The touch input can specifically be a single-click input, a long-press input, a double-click input, a swipe input, or an input along a preset trajectory. Those skilled in the art can set the specific form of the first input according to the actual situation, and no specific restrictions are made here.
[0035] S104: Send image request information to the second device.
[0036] The image request information is used to request the high-resolution image corresponding to the lightweight image from the second device.
[0037] Optionally, the image request information includes image display parameters for a high-resolution image, which are related to the input parameters of the first input.
[0038] In practical applications, image display parameters include, but are not limited to, image resolution, image sharpness, image display size, and image bitrate, etc., which are not specifically limited here.
[0039] Optionally, input parameters include, but are not limited to, input type, input position, and number of inputs, etc., without specific restrictions.
[0040] S106: Receive image data fed back by the second device.
[0041] The image data corresponds to the image display parameters.
[0042] Optionally, the image data may be the original high-resolution image stored in the second device, or it may be the image data obtained after compression, encoding, or other processing of the high-resolution image stored in the second device. No specific restrictions are imposed here.
[0043] S108: Display the image corresponding to the image data.
[0044] Specifically, in the image display method provided in this application embodiment, a first device stores a lightweight image, and a second device stores a high-resolution image corresponding to the lightweight image. When a user needs to view the high-resolution image corresponding to the lightweight image through the first device, the first device can establish a communication connection with the second device and receive a first input from the user regarding the lightweight image, wherein the first input is used to instruct the display of the high-resolution image corresponding to the lightweight image. Based on this, the first device sends image request information to the second device to request the acquisition of the high-resolution image corresponding to the lightweight image, wherein the image request information includes image display parameters of the high-resolution image, and the image display parameters are related to the input parameters of the first input. On this basis, the second device will feed back image data corresponding to the image display parameters to the first device according to the image request information. The first device receives the image data fed back by the second device and displays the image corresponding to the image data by performing operations such as decoding and rendering on the image data.
[0045] The image display method provided in this application embodiment is executed by a first device that stores lightweight images. During image display, the first device receives a first input to the lightweight image, which instructs the display of a high-resolution image corresponding to the lightweight image. It then sends image request information to a second device, requesting the acquisition of the high-resolution image corresponding to the lightweight image. The image request information includes image display parameters for the high-resolution image, which are related to the input parameters of the first input. The first device receives image data fed back by the second device, which corresponds to the image display parameters. Finally, the first device displays the image corresponding to the image data. Through this image display method, the first device stores only lightweight images, while the second device stores the high-resolution image corresponding to the lightweight image. When a user needs to view the high-resolution image corresponding to the lightweight image through the first device, based on the first input to the lightweight image, the first device obtains the image data corresponding to the image display parameters from the second device by sending image request information containing the image display parameters, and displays the image corresponding to the image data. The image display parameters are related to the input parameters of the first input. In this way, a device-coordinated image display method is achieved by using external devices such as idle devices. This allows the electronic devices actually operated by the user to store only lightweight images, reducing the amount of image data originally stored in the electronic devices. Furthermore, the image display parameters of high-resolution images are controlled by input parameters, which makes it easy to limit the amount of data loaded for high-resolution images and save local storage space on electronic devices.
[0046] In this embodiment, the first input includes a first sub-input and a second sub-input, and the image display parameters include the image resolution. Based on this, S104 may specifically include S104a and S104b as described below, and S106 may specifically include S106a and S106b as described below:
[0047] S104a: Send the first request information to the second device.
[0048] The first sub-input mentioned above is the user's touch input to the lightweight image. The touch input can be a single click, a long press, a double click, a swipe, or input along a preset trajectory. Those skilled in the art can set the specific form of the first sub-input according to the actual situation, and no specific restrictions are made here.
[0049] Optionally, the first sub-input is used to trigger a low-resolution loading of the lightweight image.
[0050] Optionally, the first request information includes a first resolution, which corresponds to a first sub-input. The first resolution is greater than the resolution of the lightweight image, and the first resolution is less than the resolution of the original image of the lightweight image.
[0051] In practical applications, the first resolution can specifically refer to the screen resolution of the first device, without any specific restrictions.
[0052] S106a: Receive the first image data sent by the second device.
[0053] The first image data corresponds to the first resolution.
[0054] Optionally, the first image data corresponds to the first image, which may specifically be the original image of the lightweight image adapted to the first resolution.
[0055] Specifically, in the image display method provided in this application embodiment, the first input includes a first sub-input, and the image display parameters include image resolution. Based on this, when a user needs to view a high-resolution image corresponding to a lightweight image through a first device, after the first device and the second device establish a communication connection, the user can send first request information containing the first resolution to the second device through the first sub-input of the lightweight image. Based on this, the second device will obtain first image data corresponding to the first resolution according to the first request information and send the first image data to the first device. The first device receives the first image data fed back by the second device and displays the first image by decoding and rendering the first image data.
[0056] S104b: Send a second request message to the second device.
[0057] The second sub-input mentioned above is the user's touch input to the lightweight image or the first image. The touch input can be a single click, a long press, a double click, a swipe, or input along a preset trajectory. Those skilled in the art can set the specific form of the second sub-input according to the actual situation, and no specific restrictions are made here.
[0058] Optionally, the second sub-input may differ from the first sub-input. For example, the first sub-input may be a swipe input, and the second sub-input may be a two-finger zoom input. Alternatively, the first sub-input may be an input to a first control such as a "Preview" button, and the second sub-input may be an input to a second control such as a "Get Original Image" button.
[0059] Optionally, the second sub-input is used to trigger high-resolution loading of the lightweight image.
[0060] Optionally, the second request information includes a second resolution, which corresponds to a second sub-input. The second resolution is greater than the first resolution, and the second resolution may specifically be the resolution of the original image of the lightweight image.
[0061] S106b: Receive second image data sent by the second device.
[0062] The second image data corresponds to the second resolution.
[0063] Optionally, the second image data corresponds to a second image, which may specifically be the original image of the lightweight image.
[0064] Specifically, in the image display method provided in this application embodiment, the first input further includes a second sub-input. Based on this, when a user needs to view a high-resolution image corresponding to a lightweight image through the first device, after the first device loads and displays the first image at the first resolution, the first device can continue to receive the user's second sub-input and send second request information containing a second resolution to the second device, wherein the second resolution is greater than the first resolution. Based on this, the second device will obtain the second image data corresponding to the second resolution according to the second request information and send the second image data to the first device. The first device receives the second image data fed back by the second device and displays the second image by decoding and rendering it.
[0065] In practical applications, after rendering the original image of the lightweight image, the first device can also cache the original image in the local storage space for direct retrieval and use later.
[0066] In the embodiments provided in this application, the first input includes a first sub-input and a second sub-input, and the image display parameters include image resolution. A first request message is sent to a second device, the first request message including the first resolution, which corresponds to the first sub-input. First image data is received from the second device, the first image data corresponding to the first resolution. A second request message is sent to the second device, the second request message including the second resolution, the second resolution corresponding to the second sub-input, and the second resolution being greater than the first resolution. Second image data is received from the second device, the second image data corresponding to the second resolution. This achieves hierarchical loading of image resolution from low to high, reducing image display bandwidth consumption and loading latency.
[0067] In this embodiment of the application, prior to S102, the image display method may further include the following S110 to S116:
[0068] S110: Send registration requests to multiple third-party devices.
[0069] Among them, multiple third devices are multiple electronic devices that store high-resolution images corresponding to the lightweight images that the user wants to view.
[0070] In practical applications, the first device can initiate registration requests to multiple third devices corresponding to the lightweight image based on the user's touch input to the lightweight image.
[0071] For example, such as Figure 2 As shown, a thumbnail 202 is displayed in the first device. The first device receives and responds to the user's click input on the thumbnail 202 and initiates registration requests to multiple third devices corresponding to the thumbnail 202.
[0072] Optionally, the plurality of third devices may include the aforementioned second device.
[0073] Optionally, the registration request may specifically be a SIP (Session Initiation Protocol) registration request, which is used for registration and connection verification between devices.
[0074] Optionally, the registration request may include screen configuration parameters of the first device.
[0075] Optionally, screen configuration parameters include, but are not limited to, the screen resolution and DPI (Dots Per Inch) of the first device, etc., without specific limitations.
[0076] Specifically, in the image display method provided in the embodiments of this application, during the process of establishing a communication connection between the first device and the second device, the first device initiates a SIP registration request to multiple third devices. The SIP registration request carries screen configuration parameters such as the screen resolution and DPI of the first device. The first device and the third devices complete parameter pass-through through a SIP custom extension header.
[0077] The SIP registration request includes the screen resolution of the first device, facilitating negotiation with the third device regarding the image size to be loaded. This allows the second device to subsequently provide corresponding image data based on the pre-negotiated resolution. This achieves image display adaptation, reducing bandwidth consumption during image display, improving loading speed, and resolving browsing lag issues.
[0078] In addition, in actual applications, before the first device initiates a SIP registration request to multiple third devices, the first device will also complete identity verification with the SIP server and the account server based on the bound account.
[0079] S112: Receive response messages from multiple third-party devices for the registration request.
[0080] The response message includes the device status information of the third device and the resolution compatibility between the image stored in the third device and the first device.
[0081] Optionally, the device status information is used to indicate the battery level and network connectivity of the third device, so as to reflect the data transmission capability of the third device.
[0082] Optionally, the resolution fit is used to indicate the degree of deviation between the resolution of the high-resolution image stored in the third device and the screen resolution of the first device. Specifically, the resolution fit can be the minimum difference between the screen resolution of the first device and the resolution of the high-resolution image stored in the third device.
[0083] Specifically, in the image display method provided in this application embodiment, after the third device receives the SIP registration request from the first device, if the registration request is successful, the third device will return a response message to the first device. The response message carries the device status information of the third device and the resolution compatibility between the image stored in the third device and the first device.
[0084] In practical applications, after the first device receives the response message sent by the third device, it can store the device status information of the third device in the local device status list.
[0085] S114: Determine the second device from multiple third devices based on device status information and resolution compatibility.
[0086] Specifically, in the image display method provided in this application embodiment, after the first device receives the response message sent by the third device, the first device can automatically select the optimal third device as the second device from multiple third devices based on the resolution compatibility between the image stored in the third device and the first device, and the locally stored device status list.
[0087] S116: Establish a communication connection with the second device.
[0088] Specifically, in the image display method provided in this application embodiment, after determining the second device from a plurality of third devices, the first device sends a SIP session establishment request to the selected second device. After receiving the SIP session establishment request, the second device establishes a signaling channel with the first device. If the establishment is successful, the second device returns an acknowledgment message to the first device, indicating that the first device and the second device have successfully established a communication connection, which can provide a reliable channel for the subsequent transmission of image data.
[0089] In practical applications, if the first device and the second device are bound to the same account, the account server can quickly trigger the communication connection between the first device and the second device by directly sending a notification.
[0090] Based on this, the communication architecture between the first device and the second device can be as follows: Figure 3As shown, during image display, the first device forwards image request information to the second device via a SIP server. The second device returns image data of a pre-negotiated size, which is then forwarded to the first device for rendering and display via a WS (WebSocket) server. In this way, the image display process is completed seamlessly using SIP, resulting in a simple, efficient, and low-latency workflow.
[0091] In addition, in practical applications, the first device also supports users manually selecting a second device. Specifically, the first device can display a device list at each location of the lightweight image, based on multiple third devices that store high-resolution images corresponding to the lightweight images. Users can then select the second device to interact with by touching the device list.
[0092] For example, such as Figure 4 As shown, a thumbnail 202 is displayed in the first device, and a device list 204 is displayed near the thumbnail 202. The device list 204 is used to indicate multiple third devices corresponding to the thumbnail 202. The first device receives and responds to the user's selection input of any third device in the device list 204, and uses the third device selected by the user as the second device to be interacted with.
[0093] The embodiments provided in this application send registration requests to multiple third devices, the registration requests including screen configuration parameters of the first device; receive response messages from the multiple third devices to the registration requests, the response messages including device status information of the third devices and the resolution adaptation of the images stored in the third devices with that of the first device; determine a second device from the multiple third devices based on the device status information and the resolution adaptation; and establish a communication connection with the second device. This achieves optimal selection of the loading source device, i.e., the second device, which can improve the stability and speed of subsequent image display.
[0094] In this embodiment of the application, the device status information includes remaining battery power information and network quality information. Based on this, the above-mentioned S114 may specifically include the following S114a and S114b:
[0095] S114a: Weighted calculation of the remaining power information, network quality information and resolution adaptation of each third device to obtain the comprehensive score of each third device.
[0096] The network quality information may specifically include the type of network the third device is connected to, such as 4G (4th Generation Mobile Communication Technology), 5G (5th Generation Mobile Communication Technology), and WiFi (Wireless Fidelity) networks. The network quality information may also include the network latency of the network the third device is connected to, but no specific restrictions are imposed here.
[0097] S114b: The third device with the highest overall score among multiple third devices is identified as the second device.
[0098] Specifically, in the image display method provided in this application embodiment, during the process of the first device selecting a second device from multiple third devices, the first device performs weighted calculations on the remaining power information, network quality information and resolution adaptation of each third device according to a preset comprehensive scoring rule to obtain a comprehensive score for each third device, and then determines the third device with the highest comprehensive score among multiple third devices as the second device.
[0099] In practical applications, when performing weighted calculations, those skilled in the art can set the weighting coefficients for remaining battery power, network quality, and resolution compatibility according to the actual situation, without making specific restrictions here.
[0100] In the embodiments provided in this application, the device status information includes remaining battery power information and network quality information. A weighted calculation is performed on the remaining battery power information, network quality information, and resolution adaptation of each third device to obtain a comprehensive score for each third device. The third device with the highest comprehensive score among multiple third devices is determined as the second device. In this way, by combining the remaining battery power information, network quality information, and resolution adaptation of different devices, the accuracy of selecting the loading source device is improved, ensuring the stability and speed of subsequent image display.
[0101] In this embodiment of the application, prior to S102, the image display method may further include S118 as described below. Furthermore, S104 may specifically include S104c and S104d as described below:
[0102] S118: Establish communication connections with multiple third-party devices.
[0103] Among them, multiple third devices include second devices.
[0104] Specifically, in the image display method provided in the embodiments of this application, such as Figure 5As shown, the first device 302 can establish near-field communication connections with multiple third devices 304, including the second device, by creating a hotspot group or the same local area network. At this time, the first device 302 and the third devices 304 exchange data in a P2P (Per-to-Per) manner.
[0105] In the process of establishing near-field communication connections between the first device and multiple third devices, identity verification can be performed through the offline mode of the bound account.
[0106] S104c: Determine the second device from multiple third devices based on the mapping address information of the high-resolution image corresponding to the lightweight image.
[0107] The mapping address information is the address information of the second database that has a mapping relationship with the lightweight image. The mapping address information can be specifically determined based on the file information of the lightweight image and the mapping relationship between the first database and the second database.
[0108] S104d: Send image request information to the second device.
[0109] Specifically, in the image display method provided in the embodiments of this application, when the first device has established a near-field communication connection with multiple third devices, the first device can receive and respond to the user's first input on a lightweight image, determine the second device from the multiple third devices according to the mapping address information of the high-resolution image corresponding to the lightweight image, and then send image request information to the second device.
[0110] The embodiments provided in this application establish communication connections with multiple third devices, including a second device; the second device is determined from the multiple third devices based on the mapping address information of the high-resolution image corresponding to the lightweight image; and an image request message is sent to the second device. This achieves a device-coordinated image display method in near-field communication scenarios, and by utilizing image mapping relationships to select the loading source device, it improves the speed and accuracy of data transmission.
[0111] In summary, this application provides a cross-platform image display scheme based on distributed storage and hierarchical loading collaboration. The overall timing diagram of the image display process can be seen as follows: Figure 6 As shown, on the first device side, such as Figure 7 As shown, the image display method provided in this application embodiment may specifically include the following steps S402 to S430:
[0112] S402: First device starts.
[0113] S404: Send SIP registration requests to multiple third-party devices.
[0114] S406: Determine if the registration request was successful. If yes, proceed to S408; otherwise, proceed to S410.

[0126] S430: Send a second request message to the second device and load and display the second image.
[0127] The image display method provided in this application can be executed by an image display device. This application uses an image display device executing the above-described image display method as an example to illustrate the image display device provided in this application.
[0128] like Figure 8 As shown, this application provides an image display device 500, which is applied to a first device. The first device stores lightweight images. The image display device 500 may specifically include a communication unit 502, a receiving unit 504, a display unit 506, and a processing unit 508.
[0129] The receiving unit 504 is used to receive a first input to the lightweight image, the first input being used to indicate the display of a high-resolution image corresponding to the lightweight image;
[0130] The communication unit 502 is used to send image request information to the second device. The image request information is used to request the second device to obtain a high-resolution image corresponding to the lightweight image. The image request information includes image display parameters of the high-resolution image, and the image display parameters are related to the input parameters of the first input.
[0131] The communication unit 502 is also used to receive image data fed back by the second device, and the image data corresponds to the image display parameters;
[0132] Display unit 506 is used to display the image corresponding to the image data.
[0133] The image display device 500 provided in this application embodiment is applied to a first device that stores lightweight images. During image display, the first device receives a first input to the lightweight image, which instructs the display of a high-resolution image corresponding to the lightweight image. It then sends image request information to a second device, requesting the acquisition of the high-resolution image corresponding to the lightweight image. The image request information includes image display parameters for the high-resolution image, which are related to the input parameters of the first input. The device also receives image data from the second device, which corresponds to the image display parameters. Finally, it displays the image corresponding to the image data. Through this image display device 500, the first device stores only lightweight images, while the second device stores the high-resolution image corresponding to the lightweight image. When a user needs to view the high-resolution image corresponding to the lightweight image through the first device, based on the first input to the lightweight image, the first device obtains the image data corresponding to the image display parameters from the second device by sending image request information containing the image display parameters, and displays the image corresponding to the image data. The image display parameters are related to the input parameters of the first input. In this way, a device-coordinated image display method is achieved by using external devices such as idle devices. This allows the electronic devices actually operated by the user to store only lightweight images, reducing the amount of image data stored in the electronic devices. Furthermore, the image display parameters of high-resolution images are controlled by input parameters, which makes it easy to limit the amount of data loaded for high-resolution images and save local storage space on electronic devices.
[0134] In this embodiment, the first input includes a first sub-input and a second sub-input, and the image display parameters include image resolution. The communication unit 502 is specifically used to: send a first request message to the second device, the first request message including a first resolution, the first resolution corresponding to the first sub-input; receive first image data sent by the second device, the first image data corresponding to the first resolution; send a second request message to the second device, the second request message including a second resolution, the second resolution corresponding to the second sub-input, the second resolution being greater than the first resolution; and receive second image data sent by the second device, the second image data corresponding to the second resolution.
[0135] In the embodiments provided in this application, the first input includes a first sub-input and a second sub-input, and the image display parameters include image resolution. A first request message is sent to a second device, the first request message including the first resolution, which corresponds to the first sub-input. First image data is received from the second device, the first image data corresponding to the first resolution. A second request message is sent to the second device, the second request message including the second resolution, the second resolution corresponding to the second sub-input, and the second resolution being greater than the first resolution. Second image data is received from the second device, the second image data corresponding to the second resolution. This achieves hierarchical loading of image resolution from low to high, reducing image display bandwidth consumption and loading latency.

This achieves optimal selection of the loading source device, i.e., the second device, which can improve the stability and speed of subsequent image display.
[0138] In this embodiment of the application, the device status information includes remaining power information and network quality information. The processing unit 508 is specifically used to: perform weighted calculation on the remaining power information, network quality information and resolution adaptation of each third device to obtain a comprehensive score for each third device; and determine the third device with the highest comprehensive score among multiple third devices as the second device.
[0139] In the embodiments provided in this application, the device status information includes remaining battery power information and network quality information. A weighted calculation is performed on the remaining battery power information, network quality information, and resolution adaptation of each third device to obtain a comprehensive score for each third device. The third device with the highest comprehensive score among multiple third devices is determined as the second device. In this way, by combining the remaining battery power information, network quality information, and resolution adaptation of different devices, the accuracy of selecting the loading source device is improved, ensuring the stability and speed of subsequent image display.
[0140] In this embodiment of the application, the communication unit 502 is specifically used for: establishing a communication connection with multiple third devices, including a second device; determining the second device from the multiple third devices based on the mapping address information of the high-resolution image corresponding to the lightweight image; and sending image request information to the second device.
