Detailed Description
The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some of the structures related to the present application are shown in the drawings, not all of the structures.
Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the steps as a sequential process, many of the steps can be performed in parallel, concurrently or simultaneously. In addition, the order of the steps may be rearranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Fig. 1 is a flowchart of a frame rate adjustment method according to an embodiment of the present disclosure, where the method may be performed by a frame rate adjustment device, where the device may be implemented by software and/or hardware, and may be generally integrated in a terminal. As shown in fig. 1, the method includes:
For example, the terminal in the embodiment of the present application may include a device provided with an operating system, such as a mobile phone, a tablet computer, a notebook computer, a handheld game console, and a smart appliance. The type of the operating system in the embodiment of the present application is not limited, and may include an Android (Android) operating system, a Windows (Windows) operating system, an apple (ios) operating system, and the like.
It should be noted that, when the target application is started or ended, the target application sends setting information to the background service of the operating system, and when the setting information is detected, a frame rate adjustment event is triggered. The target application may be an application currently started and run by the terminal. It will be appreciated that the target application may be any application installed on the terminal. For example, the target application may be a third-party game application installed in the terminal, and after the third-party game accesses the background service, the corresponding scene ID is issued when the game starts or ends. The scene ID is a unique identifier for indicating the start or end of a game, and may be a number or a character such as a combination of a letter and a number. The game application is opened and the game application is ended corresponding to different scene IDs, i.e., corresponding to different characters.
The background service may be a background Daemon preset in the terminal by a terminal manufacturer for optimizing performance/power consumption, and may be a Daemon program or the like. The Daemon () program is a server-side program that runs all the time, also called a Daemon process. The Daemon program is generally used as system service, and generally runs in a system background without a control terminal and interaction with a foreground.
Taking a game application as an example, when a scene ID issued when the game application starts is detected, a frame rate regulation event is triggered. If the scene ID corresponding to the application program can be obtained, the scene ID is compared with the ID standard characters corresponding to the application program. If the scene ID is an ID standard character which represents the start of the application under the application program, determining the scene ID issued when the game application is detected to start, and correspondingly triggering a frame rate regulation event to instruct the terminal to execute the system frame rate regulation related operation.
In this embodiment of the present application, the game information of the game at the preset office may be counted to form a sample space, which is used to calculate the average frame rate and the frame interval standard deviation, and then a frame rate adjustment event is triggered each time a scene ID issued when the game application starts is detected. The game is returned to the game hall from the end of loading to the end of game, which may be called a game, and the game information of the counted game in the preset game may form a sample space. It can be understood that, for the game application corresponding to the sample space, even if the scene ID issued when the game application is detected to start is detected, the frame rate regulation event is not triggered, but frame rate related parameters of the game are calculated, such as a reference average frame rate and a frame interval reference standard deviation.
It should be noted that, for different third party games, the definition of one game may be different and associated with the definition of the third party game. For example, for a game such as a game in which a player is glory or a battlefield is stimulated, the start and stop of a game may be from the end of loading to the end of the game, and the game returns to the game hall.
It should be noted that there are many ways to trigger the frame rate adjustment event, and the embodiment of the present application is not limited in particular. For example, when the scene identifier is a preset start identifier, the background server notifies the Surface flunger to start calculation of the average frame rate and the standard deviation of the frame interval. The frame rate adjustment event may be triggered by a notification sent by the background server to the Surface flag. For another example, when the number of game plays exceeds the preset threshold, if the scene ID issued when the game is accessed to the background service is detected again, a frame rate adjustment event is triggered, and the like.
And step 120, obtaining the average frame rate and the frame interval standard deviation of the target application in the target sampling time.
The target sampling time may be a preset time period, or a set of time intervals corresponding to the starting and ending of the target application for a preset number of times. For example, the target sampling time is 50 hours. For another example, the target sampling time is a time interval from start to end of each target application, and a set of the time intervals of a preset number of times is used as the target sampling time, or a sum of the time intervals is used as the target sampling time.
Optionally, the target sampling time may also be a time period between an opening time of a certain function in the target application and a closing time of the function, or may also be a time period of any period of time in an opening state of the target application, and of course, the target running time period may also be a time period between a starting time and an ending time when the target application runs a certain script or runs a certain copy, which is not specifically limited in this embodiment of the present invention.
Taking a game application as an example, the average frame rate may be determined according to the number of frames and the time interval in the time interval corresponding to the target application from each turn-on to turn-off within the target sampling time. The number of frames refers to the number of generated frames, that is, the number of frames processed and displayed in a period of time, and the frames may refer to still images. For example, the number of frames in the time interval corresponding to each game within the target sampling time is counted, and the reference average frame rate of each game is determined according to the ratio of the number of frames to the time interval. And determining the average frame rate according to the game number corresponding to the target sampling time and the reference average frame rate and the game number. And calculating the standard deviation of the frame interval based on the standard deviation formula according to the average frame rate. For example, the average frame rate is 50, the frame rate of each frame in the target sampling time interval (the derivative of the time for which each frame is drawn and synthesized to be displayed can be taken as the frame rate of the frame) is 50, 52, 50, 53, 50, 52, 49, 50, 49 and 45, respectively, and the calculation formula of the frame interval standard deviation is as follows:
illustratively, outside the target sampling time, the average frame rate and the standard deviation of the frame interval of the target application within the target sampling time are obtained each time the target application is started. Taking the game as an example, the target sampling time may be the time of 10 games, i.e. the sample data in the sample space is 10 sets. When detecting the scene ID issued when the game application is started and the scene ID issued when the game application is ended, considering that a game is detected, acquiring the frame number in the time interval of the game, taking the frame number and the time interval corresponding to the game as samples in the sample space, and calculating the reference average frame rate and the frame interval reference standard deviation according to the frame number and the time interval. And calculating the average frame rate and the frame interval standard deviation of 10 games according to the reference average frame rate and the frame interval reference standard deviation of each game, and storing. If the scene ID issued when the game application is started is detected again, the game information (including the average frame rate and the frame interval standard deviation) is obtained from the storage position of the average frame rate and the frame interval standard deviation.
It should be noted that, if the frame interval standard deviation is an average value of the frame interval reference standard deviations in the time intervals of starting and ending of the target application program, when the frame interval standard deviation exceeds a preset threshold, it is determined that the frame interval standard deviation meets a preset condition. If the frame interval standard deviation is a set of frame interval reference standard deviations in the time interval of starting and ending of each target application program, when at least one frame interval standard deviation exceeds a preset threshold, determining that the frame interval standard deviation meets a preset condition, and specifying the number of frame interval standard deviations exceeding the preset threshold according to actual needs to serve as a threshold for judging whether the preset condition is met.
The system frame rate may also be referred to as a frame rate of the Surface flanger (layer composition module).
For convenience of understanding, the following uses the Android system as an example, and a process from generation to display of a display screen in the Android system is briefly described. Fig. 2a is a schematic diagram of a display process according to an embodiment of the present invention.
Firstly, in an Application (Application) layer, each Application program (hereinafter, referred to as Application or APP) comprises 1 or a plurality of layers, each Application APP1, APP2, 8230, the APPN independently executes layer drawing (Render) operation (i.e. drawing images on the layers) according to the Application design condition (generally determined by the corresponding installation package APK), and after the drawing operation is finished, each Application sends all the drawn layers to a layer synthesis module (Surface maker) for executing the layer synthesis operation.
Then, at an application Framework (Framework) layer, all layers (including visible layers and invisible layers) form a layer list, which is defined as ListAll. And the layer composition module selects a visible layer from the ListAll to form a visible layer list, and the visible layer list is defined as a DisplayList. Then, the layer composition module finds out a free FB from three Frame buffers (BF or Buffer for short) that can be recycled in the system, and superimposes layers included in the DisplayList together through composition (composite) operation on the free FB according to application configuration information, such as which layer should be set at the bottom, which layer should be set at the top, which area is a visible area, and which area is a transparent area, to obtain a final picture to be displayed.
Finally, at the Kernel layer, the to-be-displayed picture can be transmitted to the Display hardware (including the Display controller and the Display screen, so that the to-be-displayed picture is finally displayed on the Display screen.
In addition, the Android system introduces a synchronous (Vsync) refresh mechanism in the display refresh process. Fig. 2b is a schematic diagram of a Vsync display refresh mechanism according to an embodiment of the present invention. Specifically, the Vsync refresh mechanism is a unified management mechanism that inserts a "heartbeat", that is, a system synchronization (Vsync) signal, in the whole display process, and the signal is sent to the CPU by the display controller to generate a Vsync interrupt, so as to control that each layer drawing operation and layer composition operation need to be completed according to the heartbeat, thereby incorporating key steps in the whole display process into the Vsync. The frequency of the Vsync signal is currently typically 60Hz. As shown in fig. 2b, assuming that the period of the Vsync signal is T, regardless of the transmission delay of the signal, after the first Vsync signal Vsync1 reaches the CPU, the CPU forwards the first Vsync signal Vsync1 to each application, and each application starts to perform a drawing operation in response to a user's touch slide or the like on the display screen; and obtaining a plurality of layers drawn by each application after each application finishes the drawing operation. After the second Vsync signal Vsync2 reaches the CPU, the CPU forwards the second Vsync signal Vsync2 to the layer composition module, and the layer composition module starts to perform layer composition operation to combine a plurality of layers drawn by each application, thereby generating a picture to be displayed. After the third Vsync signal Vsync3 reaches the CPU, the system starts to perform display refresh and finally displays the picture to be displayed on the display screen. As can be seen from the above description, the frequencies of the Vsync signals received by the application program, the layer composition module, and the display screen are consistent and are fixed values set in advance.
Illustratively, if the frame interval standard deviation meets the preset condition, the Surface flanger is notified by the background service to adjust the Vsync signal of the system, so as to fix the system frame rate to the average frame rate.
According to the technical scheme of the embodiment of the application, if the frame rate regulation event is triggered, the average frame rate and the frame interval standard deviation of the target application in the target sampling time are obtained; and when the frame interval standard deviation meets a preset condition, adjusting the system frame rate to the average frame rate. By adopting the technical scheme, the average frame rate and the frame interval standard deviation of the target application in the target sampling time can be calculated in advance, whether the system frame rate is adjusted to the average frame rate of the target application is judged based on the frame interval standard deviation, the adjustment of the system frame rate based on historical frame rate information is realized to provide a personalized frame rate regulation and control scheme, the use habits of users are effectively adapted, and the method and the system are easy to popularize to other intelligent terminals.
In some examples, detecting that the frame rate adjustment event is triggered may be performed by detecting a scene identifier corresponding to the target application; and judging whether the scene identifier is a preset opening identifier, and if so, triggering a frame rate regulation and control event. By adopting the technical scheme, the frame rate regulation and control event can be triggered when the target application is started, and the situation that the frame rate is unstable due to the fact that the system frame rate is regulated in the game running process is avoided. For example, the game application comprises high, middle and low frame rates, and if the user selects the high frame rate, the system frame rate performs drawing and displaying at the frame rate. After the system is operated for a period of time, the frame rate of the system is adjusted to the average frame rate, which may cause unstable frame rate when switching occurs, thereby affecting the smoothness of the game.
In some examples, before triggering the frame rate adjustment event, the method further includes: recording the opening times of the target application; when the times are less than the preset sampling times, determining the reference average frame rate and the frame interval reference standard deviation in the corresponding time interval from the starting to the ending of the target application each time; and when the times are equal to the preset sampling times, determining the average frame rate according to the reference average frame rate, and determining the frame interval standard deviation according to the frame interval reference standard deviation. By adopting the technical scheme, the operation data of the target application in the target time can be examined in advance, the reference frame rate and the frame interval standard deviation of each time of the operation of the target application are calculated based on the operation data, and the average frame rate and the frame interval standard deviation in the target time interval are calculated based on the reference frame rate and the frame interval standard deviation. Whether the system frame rate of the target application in the subsequent operation is regulated or not is determined based on the frame interval standard deviation in the target time interval, so that the dynamic regulation of the frame rate can be more suitable for the use habit of a user.
In some examples, after adjusting the system frame rate to the average frame rate, the method further includes:
if the scene identifier corresponding to the target application is detected to be a preset end identifier, the system frame rate is adjusted to the default frame rate by adjusting the frame synchronization information, so that the average frame rate corresponding to the target application is used as the system frame rate in the running process of the target application. By adopting the technical scheme, the system frame rate is adjusted to the average frame rate corresponding to the target application during the operation of the target application, and the system frame rate is restored to the default system frame rate of the terminal after the operation is finished, so that the condition that the display quality is influenced due to the unmatched frame rates when other applications are operated can be avoided, and the display is smoother.
Fig. 3 is a flowchart of another frame rate adjustment method according to an embodiment of the present application, and as shown in fig. 3, the method includes:
It should be noted that the scene identifier, i.e., the scene ID, is a unique identifier for indicating the start or end of the game. The target application may be a default application of the system, such as some game applications (which may be determined by analyzing historical usage data), or may be an application that the user selects on his/her own as needed. For example, when the user installs the third-party application, the application program is marked as the target application, and the target application can be stored through the white list.
Illustratively, when it is detected that the target application runs, a background server (e.g., a daemon process) obtains a scene identifier issued by the target application.
It should be noted that, when it is detected that the scene identifier of the target application is the corresponding start identifier each time, 1 is added to the start times of the target application to obtain the latest start times of the target application, and the latest start times are used as the start times of the target application.
It should be noted that the preset sampling times are defaulted by the system, or may be set by the user according to actual needs.
Illustratively, when a first scene ID issued when the game application starts and a second scene ID issued when the game application ends are detected later, it is determined that one time of game application starting to ending is detected, and a time period from the detection of the first scene ID to the detection of the second scene ID is recorded as a time interval corresponding to the time of game application starting to ending. And acquiring the number of frames in a time interval corresponding to the time interval from the starting to the ending of the game application each time. The sample space can be formed according to the number of frames and the time interval in the time interval corresponding to the starting to the ending each time. And determining the reference average frame rate and the frame interval reference standard deviation in the corresponding time interval from the start to the end of each target application according to the frame number and the corresponding time interval.
For example, if the game application is installed for the first time, after the game application accesses the background server, 10 game information of the game application running is recorded, and 10 reference average frame rates and 10 reference standard deviations of frame intervals are obtained. The average frame rate is calculated as the average of the 10 reference average frame rates. Further, the average of the 10 frame interval reference standard deviations is calculated as the frame interval standard deviation.
And 307, determining that the times are greater than the preset sampling times, and triggering a frame rate regulation event.
The frame synchronization information includes a Vsync signal, and accordingly, the adjustment of the frame synchronization information may be an adjustment of the Vsync signal, thereby realizing adjustment of parameters related to frame image display, such as a drawing frame rate, a composite frame rate, and a refresh rate.
And when the frame interval standard deviation exceeds a preset threshold value, the background service computer informs a VSYNC model of a Surface Flinger switching system so that the Surface Flinger receives Vsync signals with different frequencies.
It should be noted that the default frame rate may be understood as a frame rate value before the system frame rate is switched to the average frame rate.
In the embodiment of the present application, if the system frame rate is fixed to the average frame rate of the game application, after the game application exits, the system frame rate is restored to the default frame rate of the terminal, that is, the frame rate before the system frame rate is adjusted, or the frame rate before the game application is considered to be running.
And step 311, keeping the system frame rate unchanged.
It should be noted that, maintaining the system frame rate may be maintaining the system frame rate at the default frame rate.
According to the technical scheme of the embodiment, the reference average frame rate and the frame interval reference standard deviation in each game application operation time are determined based on the frame number and time in each game application operation time interval in the sample space, and then the average frame rate and the frame interval standard deviation of the target application in the sampling time are determined. Whether a fixed system frame rate is needed or not is judged according to a comparison result of the frame interval standard deviation and a preset threshold, if yes, the Surface flag switching system frame rate is notified through background service, system-level frame rate regulation is achieved, the use habit of a user can be effectively adapted, compared with a dynamic frame rate regulation scheme based on a white name list in the related technology, the method and the device have higher intelligence and are easy to popularize to other intelligent terminals.
