Detailed Description
To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.
In the description of the present application, it is to be understood that the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. In the description of the present application, it is to be noted that, unless otherwise explicitly specified or limited, the terms "connected" and "connected" are to be interpreted broadly, e.g., as being fixed or detachable or integrally connected; can be mechanically or electrically connected; may be directly connected or indirectly connected through an intermediate. The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art. Further, in the description of the present application, "a plurality" means two or more unless otherwise specified. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
In order to make the solution shown in the embodiments of the present application easy to understand, several terms appearing in the embodiments of the present application will be described below.
High resource occupancy scenarios: a scenario for indicating that a target application occupies processor resources above a specified threshold. In one possible implementation, if the specified threshold is 35%, when the processor resource occupied by the target application exceeds 35%, the terminal determines that the target application is currently in a high resource occupation scenario. It should be noted that the specified threshold is a value preset by a developer according to the actual performance of the target application and the terminal hardware, and the value may be determined according to the model or hardware configuration of the terminal, the performance requirement of the target application, and other actual factors, which is not limited in this embodiment of the application. Alternatively, the specified threshold may be a constant value such as 20%, 30%, 35%, or 45%, and any constant value smaller than 1 may be used as the specified threshold indicated in the embodiments of the present application, and the present application does not limit this.
Resource bottleneck scenario: and indicating that the target application is in a scene with high resource occupation scene and the time length of the scene is more than or equal to a first time length threshold value. Taking the first time threshold as 5 seconds as an example, when the duration of the target application in the high resource occupation scene is 6 seconds, the terminal confirms that the target application is in the resource bottleneck scene. It should be noted that, in one possible scenario, when the target application is in a high resource occupancy scenario, the terminal can continuously provide the corresponding resource for the target application at a higher load. However, when the target application is in a high resource occupation scene and too long, the terminal is easily unable to process the data to be processed in the target application in time, which causes a jam. Therefore, in the embodiment of the application, when it is determined that the target application is in the resource bottleneck scene, the display parameters of the target application are adjusted from the original display parameters to the display parameters corresponding to the resource bottleneck scene.
Display parameters: parameters of resolution and picture quality may be included. In one aspect, resolution, also known as resolution or resolution, may include display resolution and image resolution. In the embodiment of the present application, since the scheme is applied in a specified terminal, the display resolution may be fixed, and the change in resolution in the display parameter is used to indicate the change in resolution of the image. On the other hand, the parameter of the image quality including at least one of sharpness, dispersion degree, color gamut, color balance, or color purity is used to indicate the effect of image display.
Frame rate fluctuation value: indicating the difference between the highest frame rate and the lowest frame rate of the target application within a unit period. The unit period may be a specified unit length of time before the current system time. Alternatively, the unit length may be a constant value such as 500 milliseconds, 1 second, 2 seconds, or 5 seconds, which is not limited in the embodiment of the present application. For example, if the unit length is 1 second, and the highest frame rate of the target application within 1 second is 55 frames, and the lowest frame rate is 35 frames, the frame rate fluctuation value is 20.
Fluctuation threshold value: a threshold value for indicating whether the frame rate is stable. In the present application, if the frame rate fluctuation value exceeds the fluctuation threshold, it indicates that the frame rate of the target application is in an unstable state. If the frame rate fluctuation value does not exceed the fluctuation threshold, it indicates that the frame rate of the target application is in a stable state.
The target application comprises the following steps: refers to a designated application that can run in the operating system of the terminal and provide a visual user interface. Wherein the target application may be at least one of a gaming application, a shopping application, an instant messaging application, a blogging application, a mapping and drawing application, a text editing application, a ticketing application, a map navigation application, a video playback application, a live broadcast application, a browser application, a reading application, a music application, a financial payment application, a camera application, a photo beautification program, a smart device control application, a telephony application, a text messaging program, a weather application, a clock program, a system search application, a contacts program, a shared traffic application, a logistics application, a taxi taking application, a take-away application, an attendance card punching application, and a code scanning application.

In one possible implementation, the application that provides access via the third-party application can be used without downloading an installation package, and accordingly, does not need to be uninstalled when the application is not needed.

The third-party application may be at least one of the target applications, or may be an application such as an application market or an application store.
Alternatively, when the game application is a game application integrated in a third-party application, the game may be started by a designated start button or start operation while the third-party application is running.

The display component 160 is used to display the image frames rendered by the processor 120. When the target application is running, the display component 160 is used to display image frames of the target application that are rendered by the processor 120.
In the present application, the terminal 100 is an electronic device having an image display function. When a target application in the terminal 100 is in a resource bottleneck scene, the terminal 100 adjusts display parameters of the target application from original display parameters to display parameters corresponding to the resource bottleneck scene, the original display parameters are display parameters of the target application before the resource bottleneck scene, the resource bottleneck scene is a scene in which the duration of occupying processor resources exceeding a specified threshold is greater than or equal to a first time threshold, when the display parameters of the target application are adjusted to the display parameters corresponding to the resource bottleneck scene, a frame rate fluctuation value of the target application is obtained, and the frame rate fluctuation value is a difference value between a highest frame rate and a lowest frame rate in a unit period; when the frame rate fluctuation value of the target application is smaller than the fluctuation threshold value, adjusting the display parameters of the target application from the display parameters corresponding to the resource bottleneck scene to the original display parameters; and displaying the image of the target application according to the original display parameters.

Referring to fig. 2, fig. 2 is a flowchart illustrating a method for adjusting display parameters according to an exemplary embodiment of the present application. The method for adjusting the display parameters can be applied to the terminal shown in fig. 1. In fig. 2, the method of adjusting the display parameter includes:
step 210, when the target application is in the resource bottleneck scene, adjusting the display parameters of the target application from the original display parameters to the display parameters corresponding to the resource bottleneck scene, wherein the original display parameters are the display parameters of the target application before the resource bottleneck scene, and the resource bottleneck scene is a scene in which the time length of the occupied processor resources exceeding the specified threshold is greater than or equal to the first time length threshold.
In the embodiment of the application, the terminal can install and run the target application. When the target application runs, the terminal can detect whether the target application is in a high resource occupation scene currently. In a possible implementation manner of the embodiment of the present application, the resource occupation scenario may refer to a scenario in which processor resources are occupied beyond the specified threshold. For example, when the specified threshold is 30%, the terminal detects the processor resource occupied by the target application in real time, and when the terminal determines that the processor resource occupied by the target application exceeds 30%, the terminal determines that the target application is in a high-resource-occupied scene, in which case the terminal continues to detect the total duration of the high-resource-occupied scene of the target application. And if the duration of the high resource occupation of the target application is greater than or equal to the first duration threshold, determining that the target application is in a resource bottleneck scene. And then, the terminal can acquire the display parameters corresponding to the resource bottleneck scene and display the image of the target application according to the display parameters corresponding to the resource bottleneck scene.
In a possible implementation manner, the display parameters corresponding to the resource bottleneck scene are a set of fixed numerical values, and the terminal displays the image of the target application according to the fixed numerical values.
In another possible implementation manner, the display parameters corresponding to different scenes may be selected according to a specific value of the processor resource occupancy rate. For example, the terminal divides the value of the processor resource occupancy rate into three levels, namely a high occupancy level, a medium occupancy level and a low occupancy level. Accordingly, the display parameters may be classified into high-performance display parameters, medium-performance display parameters, and low-performance display parameters in terms of performance. Referring to table one, a possible mapping of display parameters and processor resource occupancy is shown.
Watch 1
Processor resource occupancy High occupancy level Medium occupancy level Low occupancy level
Displaying parameters High performance display parameters Middle performance display parameter Low performance display parameter
If the target application is in the resource bottleneck scene, the terminal cannot continuously provide the high-performance display parameters, the terminal adopts the display parameters corresponding to the resource bottleneck scene, and the occupation amount of the display parameters on the hardware resources is smaller than that of the hardware resources corresponding to the high-resource occupation scene. For example, the resolution corresponding to the resource bottleneck scenario may be 720p, and the resolution corresponding to the high resource occupancy scenario may be 1080 p.
Step 220, after the display parameter of the target application is adjusted to the display parameter corresponding to the resource bottleneck scene, obtaining a frame rate fluctuation value of the target application, where the frame rate fluctuation value is a difference value between a highest frame rate and a lowest frame rate in a unit period of time.
In the embodiment of the application, the terminal can obtain the frame rate fluctuation value of the target application after the display parameter of the target application is adjusted to the display parameter corresponding to the resource bottleneck scene. In a possible implementation manner, the manner in which the terminal obtains the frame rate fluctuation value may be obtained in real time. In a possible implementation manner, the manner in which the terminal obtains the frame rate fluctuation value may be periodic.
And step 230, when the frame rate fluctuation value of the target application is smaller than the fluctuation threshold, adjusting the display parameters of the target application from the display parameters corresponding to the resource bottleneck scene to the original display parameters.
In the embodiment of the application, when the target application is in the high resource occupation scene, the terminal displays the image of the target application according to the display parameters corresponding to the high resource occupation scene. Therefore, the terminal can ensure the display effect of the target application in the scene with high resource occupation. When the target application enters a resource bottleneck scene, the terminal displays the image by adopting the display parameters occupying a small amount of hardware resources. After the terminal adopts the display parameters corresponding to the resource bottleneck scene, if the image is not blocked any more during the image display, the terminal keeps a stable frame rate and has a small frame rate fluctuation value. Therefore, in this scenario, the frame rate fluctuation value of the target application is monitored, and whether the target application has departed from the resource bottleneck scenario is determined by the frame rate fluctuation value.
In this scenario, when the frame rate fluctuation value of the target application is smaller than the fluctuation threshold, it indicates that the target application is no longer in the resource bottleneck scenario, and the terminal may recover the current display parameters to recover the high-quality image display of the target application. In the embodiment of the application, the terminal acquires the original display parameters of the target application, wherein the original display parameters are the display parameters of the target application before the resource bottleneck scene. Optionally, the hardware resource occupation value corresponding to the original display parameter may be higher than the hardware resource occupation value corresponding to the display parameter corresponding to the resource bottleneck scene.
Optionally, in this embodiment of the application, the terminal may further be capable of displaying an image of the target application according to the original display parameters.
In the embodiment of the application, the terminal can display the image of the target application according to the original display parameters. The image quality and/or resolution of the target application is higher due to the original display parameters. Therefore, the embodiment provided by the application can display the image according to the display parameter corresponding to the resource bottleneck scene in time when the target application is in the resource bottleneck scene, and can also restore the original display parameter display image when the target application is no longer in the resource bottleneck scene, so that the terminal can intelligently adjust the display parameter, the utilization efficiency of the hardware resource of the terminal is improved on the premise of ensuring that the target application is not blocked, and the high display effect of the image of the target application is ensured.
In summary, according to the method for adjusting display parameters provided in this embodiment, when the target application is in the resource bottleneck scene, the display parameters of the target application are adjusted from the original display parameters to the display parameters corresponding to the resource bottleneck scene, and after the adjustment operation is completed, the frame rate fluctuation value of the target application is obtained, and when the frame rate fluctuation value of the target application is smaller than the fluctuation threshold value, the display parameters of the target application are adjusted from the display parameters corresponding to the resource bottleneck scene to the original display parameters, so that the terminal can adjust the display parameters to avoid stuttering when the resource is in the bottleneck, thereby reducing the risk of stuttering and high power consumption caused by the terminal to meet the higher performance requirement of the target application, and improving the frame rate stability under the new display parameters. On the basis, the method and the device can also recover to use the corresponding display parameters in time when the target application is no longer in the resource bottleneck, so that the target application can recover to have a higher display effect in time when the hardware resources of the terminal are not in shortage, and the resource scheduling capability of the terminal in displaying the image of the target application is improved. In a possible implementation manner, when the scheme is applied to the target application in the terminals of different models, the corresponding original display parameters and the display parameters corresponding to the bottleneck scene can be configured, so that the self-optimization capability of the target application in the terminals of different models during running is improved.
Referring to fig. 3, fig. 3 is a flowchart illustrating a method for adjusting display parameters according to another exemplary embodiment of the present application. The method for adjusting the display parameters can be applied to the terminal shown in fig. 1. In fig. 3, the method for adjusting display parameters includes:
in step 311, when the display parameter of the target application is the original display parameter, a rendering duration of the image frame of the target application rendered by the target application is detected.
In the embodiment of the application, the terminal can detect the rendering duration of one image frame in the rendering target application by the processor when the display parameter of the target application is the original display parameter.
In the embodiment of the application, the rendering duration of one image frame in the rendering target application by the processor may be an average duration of rendering a plurality of image frames by the terminal, for example, the terminal may use an average rendering duration of rendering 10 frames as the detected rendering duration.
And step 312, when the rendering duration is greater than or equal to the second duration threshold, confirming that the target application is in the resource bottleneck scene.
In an embodiment of the present application, on one hand, the terminal may use the rendering duration as a condition for confirming that the target application is in a resource bottleneck scene. On the other hand, the terminal may use the situation that the target application occupies the processor resource as a condition for confirming that the target application is in a resource bottleneck scenario.
As another way to determine the resource bottleneck scenario, when the processor resource occupied by the target application is greater than or equal to the first duration threshold, the terminal can confirm that the target application is in the resource bottleneck scenario. Wherein the processor resources may include at least one of CPU frequency, CPU load, GPU frequency, and GPU load.
When determining whether the target application is in a resource bottleneck scenario according to the situation of the processor resource occupied by the target application, the terminal may select one of the steps 321, 322, 323, and 324 to execute, or may select at least two of the steps to execute. When the terminal selects at least two steps to execute, the terminal may execute the selected steps simultaneously or in a preset execution order. Optionally, the step numbers in this embodiment are only different from the exemplary distinguishing steps, and do not limit the execution sequence between the steps.
In step 321, when the duration that the CPU load occupied by the target application is higher than the first load threshold is greater than or equal to the first duration threshold, it is determined that the target application is in a resource bottleneck scene.
In the embodiment of the application, the terminal can determine whether to display the image of the target application according to the display parameters corresponding to the resource bottleneck scene according to the CPU load occupied by the target application. When the duration that the CPU load occupied by the target application is higher than the first load threshold is greater than or equal to the first duration threshold, the terminal can confirm that the target application is in a resource bottleneck scene. It should be noted that the first load threshold may be a constant value preset by a developer, and the constant value may be associated with parameters such as a model of the terminal or a configuration of a target application.
And 322, when the time length of the GPU load occupied by the target application is higher than the second load threshold is larger than or equal to the first time length threshold, confirming that the target application is in a resource bottleneck scene.
In the embodiment of the application, the terminal can confirm that the target application is in a resource bottleneck scene when the GPU load occupied by the target application is higher than the second load threshold.
Step 323, when the duration that the CPU frequency occupied by the target application is higher than the first frequency threshold is greater than or equal to the first duration threshold, determining that the target application is in a resource bottleneck scene.
And 324, when the time length of the GPU frequency occupied by the target application is higher than the second frequency threshold is larger than or equal to the first time length threshold, confirming that the target application is in a resource bottleneck scene.
Step 331, when the target application is in the resource bottleneck scenario, a signaling interface in the operating system is called to send a first signal to an engine in the target application.
In the embodiment of the application, when the terminal confirms that the target application is in the resource bottleneck scene, the terminal can call a signal sending interface in the operating system to send a first signal to an engine side in the target application, so that the engine in the target application is notified to acquire information of the resource bottleneck scene.
Step 332, when the engine receives the first signal through the signal receiving interface, adjusting the display parameter of the target application from the original display parameter to the display parameter corresponding to the resource bottleneck scene.
In an embodiment of the application, a target application controls the display of the application through an engine embedded in the application. When the engine receives the first signal through the signal, the terminal adjusts the display parameter of the target application from the original display parameter to the display parameter corresponding to the resource bottleneck scene. Optionally, after the display parameter is adjusted, the terminal may further display the image of the target application according to the display parameter. Or, after the display parameters are adjusted, the terminal may further calculate corresponding image data according to the display parameters to generate an image frame to be displayed.
In one possible embodiment of the application, the terminal is capable of controlling the engine to reduce the resolution of the image of the target application from the original display parameters to the target resolution. In the embodiment of the application, the engine in the target application can control the resolution of the target application, and when the resolution of the target application is reduced, the definition of the target application when being displayed will be reduced, and the terminal will have more hardware resources to prevent the terminal from generating the stuck phenomenon.
In one possible embodiment of the present application, the terminal can control the engine to reduce the image quality of the target application from an original image quality to a target image quality. In the embodiment of the application, the engine in the target application can reduce the image quality of the engine to the target image quality, so that the terminal has more hardware resources to prevent the terminal from generating a pause phenomenon.
Step 341, obtaining a frame rate maximum value and a frame rate minimum value in a target unit time period, where the target unit time period is a time period of a preset length before the current system time.
In the embodiment of the application, the terminal can acquire the maximum value of the frame rate and the minimum value of the frame rate in the target unit period. It should be noted that the maximum value of the frame rate and the minimum value of the frame rate acquired by the terminal in the target unit period are related to the sampling period of the frame rate acquired by the terminal, and the terminal records the maximum value of the frame rate and the minimum value of the frame rate acquired in the target unit period. The length of the target unit period is a preset length, which is 5 seconds, 10 seconds, or other length of time. The length value of the target unit time interval is not limited in the embodiment of the application, and the duration of the embodiment of the application can be used as the length of the target unit time interval.
In step 342, the maximum value and the minimum value are subtracted to obtain the frame rate fluctuation value.
In the embodiment of the application, after the terminal obtains the maximum value and the minimum value, the terminal can make a difference between the maximum value and the minimum value to obtain a frame rate fluctuation value, where the frame rate fluctuation value is used to indicate the frame stability of the target application in a target unit time period, and also can indicate whether the resources obtained by the target application in the time period can support the normal operation of the target application. In a possible case, when the frame rate fluctuation value is small, the target application runs more stably, which indicates that the hardware resources acquired by the target application in the period are more abundant, and the occupation is likely to be wasted.
And 343, when the frame rate fluctuation value is smaller than the fluctuation threshold, adjusting the display parameters of the target application from the display parameters corresponding to the resource bottleneck scene to the original display parameters.
In the embodiment of the application, when the frame rate fluctuation value is smaller than the fluctuation threshold value and the image is displayed according to the display parameters corresponding to the resource bottleneck scene, the terminal can adjust the display parameters of the target application from the display parameters corresponding to the resource bottleneck scene to the original display parameters.
It should be noted that the original display parameter may be recorded in the running log of the target application, or may be recorded in a temporary folder indicated by the system service, which is not limited in this embodiment of the present application.
And step 350, displaying the image of the target application according to the original display parameters.
In the embodiment of the application, the terminal can also display the image of the target application according to the original display parameters.
In summary, in this embodiment, whether the target application is in a scene with high resource occupancy may be determined according to a situation that the target application occupies a CPU load or a GPU load, if the target application is in the scene with high resource occupancy, the terminal reduces the resolution of the target application to the target resolution, and reduces the image quality of the target application to the target image quality, so as to ensure smooth operation of the target application in the scene with high resource occupancy, and meanwhile, when the terminal detects that the frame rate fluctuation value of the target application is smaller than the fluctuation threshold, the terminal obtains the original display parameters of the target application, and displays an image according to the original display parameters, so as to improve the display effect of the target application in the scene with low resource occupancy.
The method for adjusting display parameters provided by this embodiment can also obtain a maximum value and a minimum value of the frame rate in a target unit time period, obtain a frame rate fluctuation value through a difference between the maximum value and the minimum value, determine whether to obtain an original display parameter of the target application through a comparison between the frame rate fluctuation value and a fluctuation threshold value, and after obtaining the original display parameter, enable the target application to resume displaying a display parameter display image before displaying the image by using the display parameter corresponding to the high resource occupation scene, thereby improving an effect of displaying the image of the target application by the terminal.
