[0002] The implementation of cloud gaming involves a cloud server encoding the game screen into a cloud game video stream, which is then pushed to the terminal. The terminal displays the game screen based on the received cloud game video stream.

[0003] Currently, cloud gaming image quality adjustment mainly relies on two aspects: one is to perform image quality processing before cloud encoding and streaming, but this will bring additional computing pressure to the cloud; the other is to perform image quality processing after the terminal receives the video stream and then display the image. However, it is often difficult to meet the dynamic image quality processing needs of different scenes in the game when adjusting the image quality on the terminal. Summary of the Invention

[0020] According to another embodiment of this application, a storage medium stores a computer program thereon, which, when executed by a computer's processor, causes the computer to perform the methods described in the embodiments of this application.

[0032] The present disclosure will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the embodiments provided herein are merely illustrative of the present disclosure and are not intended to limit the present disclosure. Furthermore, the embodiments provided below are some embodiments for implementing the present disclosure, and not all embodiments for implementing the present disclosure.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure.

[0036] Figure 1 A flowchart illustrating a cloud gaming image quality adjustment method according to an embodiment of this application is shown. Figure 1 The cloud gaming graphics quality adjustment method shown can be executed by any cloud server with processing power.

[0037] like Figure 1 As shown, the cloud gaming image quality adjustment method may include steps S110 to S140.

[0038] Step S110: Obtain the terminal display features corresponding to the cloud game screen, including target resolution, number of scene objects, viewing angle distance, and anti-aliasing settings; Step S120: Determine whether the target resolution, number of scene objects, viewing angle distance, and anti-aliasing settings meet the image quality pre-adjustment conditions; Step S130: If the image quality pre-adjustment conditions are met, perform image quality pre-adjustment on the cloud game screen to obtain the adjusted game screen; Step S140: Encode the adjusted game screen to obtain a cloud game video stream, and send the cloud game video stream to the terminal for cloud game screen display.

[0039] In this manner, based on steps S110 to S140, the cloud server can acquire terminal display characteristics such as the target resolution, number of scene objects, viewing angle, and anti-aliasing settings of the cloud game screen before encoding it into a video stream. When it determines that the terminal display characteristics meet the image quality pre-adjustment conditions, it performs image quality pre-adjustment on the cloud game screen to obtain the adjusted game screen. Then, it encodes the adjusted game screen to obtain the cloud game video stream and sends it to the terminal for display. Furthermore, the cloud server only performs image quality pre-adjustment when the terminal display characteristics meet the image quality pre-adjustment conditions, rather than pre-adjusting for all screens, avoiding unnecessary computational pressure on the cloud server. Moreover, the cloud server's adjustment can easily meet the needs of different dynamic image quality processing for different scenes within the game.

[0040] The following description Figure 1 The embodiments describe the steps involved in adjusting the image quality of cloud games and the specific embodiments that can be further selected under each step.

[0041] Step S110: Obtain the terminal display features corresponding to the cloud gaming screen. The terminal display features include target resolution, number of scene objects, viewing angle distance, and anti-aliasing settings.

[0042] The cloud server can obtain the terminal display characteristics of the cloud game screen to be displayed on the terminal. The terminal display characteristics are the key features displayed on the terminal. The terminal display characteristics can include the target resolution, the number of objects in the scene, the viewing angle, and anti-aliasing settings.

[0043] The target resolution is the resolution set in the terminal for displaying the cloud game screen, and it can be obtained from the terminal. The number of scene objects is the number of scene objects included in the cloud game screen, such as virtual characters or virtual equipment, etc. The number of scene objects can be identified from the cloud game screen.

[0044] The field of view refers to the range and level of detail in the cloud game visuals that the user can see. This field of view can be obtained from the cloud game settings on the device. Anti-aliasing settings refer to the anti-aliasing configuration on the device, which can also be obtained from the cloud game settings on the device.

[0045] Step S120: Determine whether the target resolution, the number of scene objects, the distance of the viewing angle, and the anti-aliasing settings meet the image quality pre-adjustment conditions.

[0046] The image quality pre-adjustment conditions are preset conditions used to determine whether image quality pre-adjustment should be performed on the cloud server. Judging whether several terminal display characteristics, such as target resolution, number of objects in the scene, viewing angle distance, and anti-aliasing settings, meet the image quality pre-adjustment conditions can effectively assess the necessity of image quality pre-adjustment on the cloud server.

[0047] In one embodiment, determining whether the target resolution, the number of objects in the scene, the viewing angle distance, and the anti-aliasing settings meet the image quality pre-adjustment conditions includes:

[0048] The system determines whether the target resolution is higher than a predetermined resolution, whether the number of objects in the scene is greater than a predetermined number, whether the viewing distance is less than a predetermined distance, and whether anti-aliasing is enabled in the anti-aliasing settings, to obtain multiple first judgment results; if at least one of the multiple first judgment results is yes, then it is determined that the image quality pre-adjustment conditions are met.

[0049] The cloud server can obtain a first judgment result by determining whether the target resolution is higher than the predetermined resolution, whether the number of objects in the scene is greater than the predetermined number, whether the viewing distance is less than the predetermined distance, and whether anti-aliasing is enabled in the anti-aliasing settings, thereby obtaining multiple first judgment results.

[0050] Furthermore, if at least one of the multiple first judgment results is true, then the terminal display characteristics are determined to meet the image quality pre-adjustment conditions. That is, if the cloud server determines that any one of the following conditions is met: the target resolution is higher than a predetermined resolution, the number of objects in the scene is greater than a predetermined number, the viewing distance is less than a predetermined distance, or anti-aliasing is enabled, then the image quality pre-adjustment conditions are currently met. Determining that the image quality pre-adjustment conditions are met based on the satisfaction of any one of these terminal display characteristics reliably confirms the necessity for image quality pre-adjustment on the cloud server.

[0051] In one embodiment, determining whether the target resolution, the number of objects in the scene, the viewing angle distance, and the anti-aliasing settings meet the image quality pre-adjustment conditions includes:

[0052] Obtain predetermined terminal-related data from the terminal and predetermined cloud-related data from the cloud server; based on the predetermined terminal-related data and the predetermined cloud-related data, determine the matching resolution threshold, number of objects, distance threshold, predetermined level, and pass result combination; determine whether the target resolution is higher than the resolution threshold, whether the number of objects in the scene is greater than the number of objects, whether the distance of the viewing angle is less than the distance threshold, and whether the anti-aliasing level in the anti-aliasing settings is higher than the predetermined level, to obtain multiple second judgment results; if the multiple second judgment results meet the pass result combination, it is determined that the image quality pre-adjustment conditions are met.

[0053] The data related to the pre-ordered terminal refers to data specific to the pre-ordered terminal. This data may include, but is not limited to, the terminal model, the user's visual acuity parameters, and the terminal's vibration data. The cloud server can obtain the pre-ordered terminal data from the terminal in real time.

[0054] The reserved cloud-related data refers to data stored on a reserved cloud server. This data may include, but is not limited to, throughput, concurrent users, response time, and resource utilization. The cloud server can obtain the reserved cloud-related data in real time.

[0055] The cloud server can use a large language model or a dedicated parameter analysis model to analyze the relevant data of the predetermined terminal and the relevant data of the predetermined cloud, thereby dynamically combining the relevant data in the cloud server and the terminal to determine the more suitable resolution threshold, number of objects, distance threshold, predetermined level, and result combination.

[0056] The cloud server can further determine whether the target resolution is higher than the resolution threshold to obtain a second judgment result 1, whether the number of objects in the scene is greater than the number of objects to obtain a second judgment result 2, whether the viewing distance is less than the distance threshold to obtain a second judgment result 3, and whether the anti-aliasing level in the anti-aliasing settings is higher than the predetermined level to obtain a second judgment result 4, thereby obtaining multiple second judgment results.

[0057] Furthermore, if multiple second judgment results match the combination of passing results, then it is determined that the current image quality pre-adjustment condition is met. For example, if a combination of passing results is that both second judgment result 1 and second judgment result 3 are yes, then the cloud server determines that the current image quality pre-adjustment condition is met if it determines that the target resolution is higher than the resolution threshold and the viewing distance is less than the distance threshold.

[0058] It is understood that as the relevant data of the predetermined terminal and the relevant data of the predetermined cloud change dynamically, the resolution threshold, the number of objects, the distance threshold, the predetermined level, and the combination of results also change dynamically. The cloud server can dynamically determine whether the current image quality pre-adjustment conditions are met based on the relevant data, and further reliably determine whether there is a need to pre-adjust the image quality in the cloud server.

[0059] Step S130: If the image quality pre-adjustment conditions are met, the image quality of the cloud game screen is pre-adjusted to obtain the adjusted game screen. Step S140: The adjusted game screen is encoded to obtain a cloud game video stream, and the cloud game video stream is sent to the terminal for cloud game screen display.

[0060] When the cloud server determines that the terminal's display characteristics meet the image quality pre-adjustment conditions, it performs image quality pre-adjustment on the cloud game screen, resulting in an improved game screen. This improved game screen can be either a first or a second improved screen. Then, the improved game screen is encoded to obtain a cloud game video stream, which is sent to the terminal. The terminal can decode the cloud game video stream to obtain the improved game screen for display. The cloud server only performs image quality pre-adjustment when the terminal's display characteristics meet the conditions, avoiding pre-adjustment for all screens. This avoids unnecessary computational load on the cloud server, and the cloud server-side adjustments easily meet the dynamic image quality processing requirements of different scenes within the game.

[0061] In one embodiment, the adjusted game screen includes a first adjusted screen; the step of pre-adjusting the image quality of the cloud gaming screen to obtain the adjusted game screen includes: determining a first cloud-based image quality adjustment parameter corresponding to the cloud gaming screen; performing image quality pre-adjustment on the cloud gaming screen according to the first cloud-based image quality adjustment parameter to obtain the first adjusted screen; correspondingly, the step of encoding the adjusted game screen to obtain a cloud gaming video stream and sending the cloud gaming video stream to the terminal for displaying the cloud gaming screen includes: encoding the first adjusted screen to obtain a cloud gaming video stream and sending the cloud gaming video stream to the terminal, so that the terminal decodes the first adjusted screen from the cloud gaming video stream for display. 。

[0062] The cloud server can use a large language model or a dedicated image quality processing and analysis model to analyze the cloud game image and determine the first cloud image quality adjustment parameters to match the image. These first cloud image quality adjustment parameters may include, but are not limited to, contrast, saturation, and other image quality adjustment parameters. The cloud server can then perform pre-adjustment of the cloud game image quality based on these first cloud image quality adjustment parameters to obtain the first adjusted image.

[0063] Furthermore, the cloud server can encode the first adjusted image to obtain a cloud gaming video stream, and send the cloud gaming video stream to the terminal. The terminal can then decode the first adjusted image from the cloud gaming video stream and display it. That is, after the cloud server pre-adjusts the image quality of the cloud gaming image according to the first cloud image quality adjustment parameters, the terminal does not perform any further image quality adjustments.

[0064] In one embodiment, the adjusted game screen includes a second adjusted screen; the step of pre-adjusting the image quality of the cloud gaming screen to obtain the adjusted game screen includes: obtaining second cloud image quality adjustment parameters and terminal image quality adjustment parameters based on the predetermined terminal-related data and the predetermined cloud-related data; performing image quality pre-adjustment on the cloud gaming screen according to the first cloud image quality adjustment parameters to obtain the second adjusted game screen; correspondingly, the step of encoding the adjusted game screen to obtain a cloud gaming video stream and sending the cloud gaming video stream to the terminal for displaying the cloud gaming screen includes: encoding the second adjusted screen to obtain a cloud gaming video stream, and sending the cloud gaming video stream and the terminal image quality adjustment parameters to the terminal, so that the terminal decodes the second adjusted screen from the cloud gaming video stream, and performs image quality adjustment on the second adjusted screen according to the terminal image quality adjustment parameters to obtain a third adjusted screen for display. 。

[0065] The cloud server can use a large language model or a dedicated image quality processing and analysis model to analyze the predetermined terminal-related data, the predetermined cloud-related data, and the cloud game screen to determine the second cloud-based image quality adjustment parameters and the terminal image quality adjustment parameters. The second cloud-based image quality adjustment parameters and the terminal image quality adjustment parameters may include, but are not limited to, image quality adjustment parameters such as contrast and saturation.

[0066] The second cloud-based image quality adjustment parameters are those used in the cloud server for image quality adjustment, and the terminal image quality adjustment parameters are those used in the terminal for image quality adjustment. The cloud server can pre-adjust the image quality of the cloud game screen according to the second cloud-based image quality adjustment parameters to obtain a second adjusted image. Then, the cloud server can encode the second adjusted image to obtain a cloud game video stream, and send the cloud game video stream and the terminal image quality adjustment parameters to the terminal. The terminal can decode the cloud game video stream to obtain the second adjusted image, and adjust the image quality of the second adjusted image according to the terminal image quality adjustment parameters to obtain a third adjusted image for display.

[0067] In this embodiment, the cloud gaming system performs some image quality preprocessing on the cloud server, while the terminal further adjusts the image quality of the preprocessed second adjusted image. The cloud server and the terminal work together to adjust the image quality, and the capabilities of the cloud server and the terminal are utilized in a balanced way, which further improves the system performance of the cloud gaming system.

[0068] In some embodiments, the cloud server determines that if the image quality pre-adjustment conditions are not met, it will not pre-adjust the image quality of the cloud game screen, but will directly encode the cloud game screen to obtain a cloud game video stream, and send the cloud game video stream to the terminal. After the terminal decodes the cloud game screen, it will automatically adjust the image quality of the cloud game screen and then display the cloud game screen.

[0069] Figure 2 A flowchart illustrating a cloud gaming image quality adjustment method according to an embodiment of this application is shown. Figure 2 The cloud gaming image quality adjustment method shown can be executed by any terminal with processing capabilities.

[0070] like Figure 2 As shown, the cloud gaming image quality adjustment method may include steps S210 to S220.

[0071] Step S210: Receive a cloud gaming video stream sent by a cloud server, wherein the cloud gaming video stream is obtained by the cloud server encoding the adjusted game screen, and the adjusted game screen is obtained by the cloud server performing image quality pre-adjustment on the cloud gaming screen when it determines that the terminal display characteristics of the cloud gaming screen meet the image quality pre-adjustment conditions, wherein the terminal display characteristics include target resolution, number of scene objects, viewing angle distance, and anti-aliasing settings; Step S220: Display the cloud gaming screen according to the cloud gaming video stream.

[0072] In this manner, based on steps S210 to S220, the cloud server can acquire terminal display characteristics such as target resolution, number of scene objects, viewing angle, and anti-aliasing settings of the cloud game screen before encoding it into a video stream. When it determines that the terminal display characteristics meet the image quality pre-adjustment conditions, it performs image quality pre-adjustment on the cloud game screen to obtain the adjusted game screen. Then, it encodes the adjusted game screen to obtain the cloud game video stream and sends it to the terminal for display. Furthermore, the cloud server only performs image quality pre-adjustment when the terminal display characteristics meet the image quality pre-adjustment conditions, rather than pre-adjusting for all screens, avoiding unnecessary computational pressure on the cloud server. Moreover, the cloud server's adjustment can easily meet the needs of different dynamic image quality processing for different scenes within the game.

[0073] In one embodiment, the adjusted game screen includes a first adjusted screen or a second adjusted screen; the display of the cloud game screen based on the cloud game video stream includes one of the following methods: first, decoding the first adjusted screen from the cloud game video stream and displaying it using the first adjusted screen; second, decoding the second adjusted screen from the cloud game video stream, and adjusting the image quality of the second adjusted screen according to the terminal image quality adjustment parameters issued by the cloud server to obtain a third adjusted screen, and displaying it using the third adjusted screen.

[0074] In the first approach, the cloud server can use a large language model or a dedicated image quality processing and analysis model to analyze the cloud game screen and determine the first cloud image quality adjustment parameters matching the cloud game screen. These first cloud image quality adjustment parameters may include, but are not limited to, contrast, saturation, and other image quality adjustment parameters. The cloud server can pre-adjust the image quality of the cloud game screen based on these first cloud image quality adjustment parameters to obtain the first adjusted image. Further, the cloud server can encode the first adjusted image to obtain a cloud game video stream and send it to the terminal. The terminal can then decode the cloud game video stream to obtain the first adjusted image and display it. That is, after the cloud server pre-adjusts the image quality of the cloud game screen based on the first cloud image quality adjustment parameters, no further image quality adjustments are performed on the terminal.

[0075] In the second approach, the second cloud-based image quality adjustment parameters are those used on the cloud server for image quality adjustment, and the terminal image quality adjustment parameters are those used on the terminal for image quality adjustment. The cloud server can pre-adjust the cloud gaming screen's image quality based on the second cloud-based image quality adjustment parameters to obtain a second adjusted image. Then, the cloud server can encode the second adjusted image to obtain a cloud gaming video stream and send the cloud gaming video stream and the terminal image quality adjustment parameters to the terminal.
