The method of this embodiment can be executed by a device for controlling the frame rate of a mobile terminal, which can be implemented through hardware and/or It is realized by means of software, and the device can be set inside the mobile terminal as a part of the mobile terminal.
如图1所示，本实施例提供的移动终端帧率的控制方法包括以下步骤：As shown in Figure 1, the method for controlling the frame rate of a mobile terminal provided in this embodiment includes the following steps:
步骤101、确定移动终端的显示屏的刷新率大于第一设定值。Step 101. Determine that the refresh rate of the display screen of the mobile terminal is greater than a first set value.
为了便于理解，下面以Android系统为例，对Android系统中显示画面从生成到显示的过程进行简单的说明。图2为本发明一个实施例提供的一种显示过程的示意图。For ease of understanding, the Android system is taken as an example below to briefly describe the process from generation to display of the display screen in the Android system. Fig. 2 is a schematic diagram of a display process provided by an embodiment of the present invention.
首先，在应用(Application)层，每个应用程序(以下简称应用或APP)按照自己的应用设计情况(一般由对应的安装包APK决定)各自单独执行图像绘制(Render)操作，并在绘制操作处理完成后，各应用将所绘制的所有图像发送给执行图像合成操作的合成模块(Surface flinger)。First, at the application layer, each application (hereinafter referred to as application or APP) executes the image rendering (Render) operation independently according to its own application design (generally determined by the corresponding installation package APK). After the processing is completed, each application sends all the drawn images to a composite module (Surface flinger) that performs image composite operations.
然后，在应用框架(Framework)层，系统有三个帧缓冲器(Frame Buffer，FB)，三个FB可以循环使用。Surface flinger从三个FB中找出一个空闲的FB，并在该空闲的FB上，根据应用配置信息，例如哪个图像应该置底、哪个图像应该置顶、哪个图像采用透底效果等，通过合成(Compose)操作，将各个应用分别绘制的多个图像叠加在一起，得到最终显示的显示帧(待显示画面)。Then, in the application framework (Framework) layer, the system has three frame buffers (Frame Buffer, FB), and the three FBs can be used cyclically. Surface flinger finds an idle FB from the three FBs, and on the idle FB, according to the application configuration information, such as which image should be placed at the bottom, which image should be placed at the top, and which image should use the bottom effect, etc., through compositing (Compose ) operation to superimpose multiple images drawn by each application to obtain a final displayed display frame (image to be displayed).
最后，在内核(Kernel)层，可以将待显示画面通过移动终端显示处理(MobileDisplay Process，MDP)模块传输给显示硬件(包括显示控制器和显示屏，使待显示画面最终显示在显示屏上。这里对显示屏的类型不做限定，例如可以是液晶显示器(LiquidCrystal Display，LCD)。Finally, at the kernel (Kernel) layer, the picture to be displayed can be transmitted to the display hardware (including a display controller and a display screen) through a mobile terminal display processing (Mobile Display Process, MDP) module, so that the picture to be displayed is finally displayed on the display screen. The type of the display screen is not limited here, for example, it may be a liquid crystal display (LiquidCrystal Display, LCD).
另外，Android系统在显示刷新的过程中，引入了同步(Vsync)刷新机制。图3给出了本发明一个实施例提供的Vsync显示刷新机制的示意图。具体地，Vsync刷新机制其实就是在整个显示流程中，插入“心跳”即系统同步(Vsync)信号，由显示控制器发送给CPU，用于产生Vsync中断，以控制每次Render操作和Compose操作都需要按照心跳来完成，从而将整个显示过程中的关键步骤都纳入到Vsync的统一管理机制。Vsync信号频率目前常见为60Hz。In addition, the Android system introduces a synchronous (Vsync) refresh mechanism during the display refresh process. FIG. 3 shows a schematic diagram of a Vsync display refresh mechanism provided by an embodiment of the present invention. Specifically, the Vsync refresh mechanism is actually to insert a "heartbeat" or system synchronization (Vsync) signal in the entire display process, which is sent by the display controller to the CPU to generate a Vsync interrupt to control the timing of each Render operation and Compose operation. It needs to be completed according to the heartbeat, so that the key steps in the entire display process are included in the unified management mechanism of Vsync. The frequency of the Vsync signal is currently 60 Hz.
如图3所示，假设Vsync信号周期为T，不考虑信号的传输延迟，第一个Vsync信号Vsync1到达CPU后，CPU控制合成模块向各应用转发该第一个Vsync信号Vsync1，各应用响应于用户在显示屏上的触摸滑动等操作，开始执行Render操作；并在各应用完成Render操作后，得到各应用所绘制的多个图像。第二个Vsync信号Vsync2到达CPU后，CPU控制显示控制器向合成模块转发该第二个Vsync信号Vsync2，合成模块开始执行图像合成操作，将各应用所绘制的多个图像进行合成，生成待显示画面。第三个Vsync信号Vsync3到达CPU后，系统开始执行显示刷新，并将该待显示画面最终显示在显示屏上。As shown in Figure 3, 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 controls the synthesis module to forward the first Vsync signal Vsync1 to each application, and each application responds to The user performs operations such as touch and slide on the display screen to start the Render operation; and after each application completes the Render operation, multiple images drawn by each application are obtained. After the second Vsync signal Vsync2 reaches the CPU, the CPU controls the display controller to forward the second Vsync signal Vsync2 to the compositing module, and the compositing module starts to perform the image compositing operation, compositing multiple images drawn by each application to generate images to be displayed picture. 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.
在移动终端图像绘制、合成和刷新显示的流程中，存在3种帧率：绘制帧率、合成帧率和刷新率。In the process of drawing, compositing and refreshing the display of images on the mobile terminal, there are three frame rates: frame rate for drawing, frame rate for compositing and refresh rate.
其中，绘制帧率为应用程序在图像绘制完成后，触发合成模块合成的帧率，可以理解为应用程序单位时间(例如，1秒钟)绘制图像的次数。Wherein, the drawing frame rate is the frame rate at which the application program triggers the composition module to synthesize after the image drawing is completed, which can be understood as the number of times the application program draws the image per unit time (for example, 1 second).
合成帧率为把各个应用程序的绘制图像合成为一个待显示画面的帧率。Compositing frame rate is the frame rate for compositing the drawn images of various application programs into a frame to be displayed.
刷新率为移动终端显示屏显示画面刷新的帧率。The refresh rate refers to the frame rate at which the display screen of the mobile terminal is refreshed.
本发明的帧率控制方法主要涉及上述待显示画面显示流程中的图像绘制操作。其中，绘制操作的执行方式，可以为软件方式、硬件方式或其他方式。软件方式一般是在移动终端设备的CPU中使用算法实现绘制操作。硬件方式一般是在移动终端设备的GPU(GraphicProcessing Unit，图形处理器)或移动终端显示处理(Mobile Display Process，MDP)模块中使用专用芯片来实现绘制操作。The frame rate control method of the present invention mainly involves the image drawing operation in the display process of the above-mentioned picture to be displayed. Wherein, the execution mode of the drawing operation may be software mode, hardware mode or other modes. The software method generally uses an algorithm in the CPU of the mobile terminal device to implement the drawing operation. The hardware method generally uses a dedicated chip in a GPU (Graphic Processing Unit, Graphics Processing Unit) or a mobile terminal display processing (Mobile Display Process, MDP) module of the mobile terminal device to implement the drawing operation.
不同性能的移动终端所支持的最大刷新率也不同，例如60HZ、75HZ和120HZ等。一般，移动终端都是以固定的刷新率在刷新，当移动终端的刷新率较大时，有一些应用程序的绘制帧率会比较大，刷新频率也比较高，但其实际所需要绘制和刷新的频率并不是很大，那么这些应用程序的绘制和刷新操作将会给移动终端带来不必要的功耗。Mobile terminals with different performances support different maximum refresh rates, such as 60HZ, 75HZ, and 120HZ. Generally, mobile terminals are refreshed at a fixed refresh rate. When the refresh rate of the mobile terminal is relatively high, some applications have a relatively high drawing frame rate and a relatively high refresh rate, but the actual drawing and refreshing required The frequency of the application is not very high, then the drawing and refresh operations of these applications will bring unnecessary power consumption to the mobile terminal.
该步骤的作用于是确定显示屏的刷新率为较大的刷新率。例如，所述第一设定值可取值70HZ或者100HZ等。The function of this step is to determine the higher refresh rate of the display screen. For example, the first set value may take a value of 70HZ or 100HZ or the like.
步骤102、从当前运行的各个应用程序中确定满足设定降帧率条件的目标应用程序。Step 102: Determine the target application program that satisfies the set frame rate reduction condition from the currently running application programs.
其中，所述满足降帧率条件的应用程序可以为应用属性为设定属性的应用程序，例如，将应用类型为阅读器或者通讯录等画面更新较慢的应用程序确定为满足降帧率条件的应用程序，或者将优先级低的应用程序确定为满足降帧率条件的应用程序。Wherein, the application that satisfies the frame rate reduction condition may be an application program whose application attribute is a set attribute, for example, an application whose screen update is slow such as a reader or an address book is determined to meet the frame rate reduction condition applications, or determine an application with a low priority as an application that satisfies the frame rate reduction condition.
该步骤还可以包括：获取当前运行的各个应用程序的实时绘制帧率；根据所述各个应用程序的实时绘制帧率确定满足设定降帧率条件的目标应用程序。将实时绘制帧率与实际所需要的绘制帧率相差较大应用程序确定为目标应用程序。This step may also include: acquiring the real-time rendering frame rate of each currently running application program; and determining the target application program that satisfies the set frame rate reduction condition according to the real-time rendering frame rate of each application program. The application that has a large difference between the real-time rendering frame rate and the actual required rendering frame rate is determined as the target application.
其中，所述获取当前运行的各个应用程序的实时绘制帧率可以包括：获取所述各个应用程序的实时绘制帧率，以及设定白名单中所述各个应用程序对应的设定绘制帧率。相应的，所述根据所述各个应用程序的实时绘制帧率确定满足设定降帧率条件的目标应用程序可以包括：将所述各个应用程序分别作为当前应用程序；若当前应用程序的实时绘制帧率与对应的设定绘制帧率的差值大于第二设定值，则将当前应用程序确定为目标应用程序，所述第二设定值大于0。其中，所述白名单中包括各个应用程序对应的设定绘制帧率，所述设定绘制帧率可以为根据经验值确定的应用程序实际所需的绘制帧率，即应用程序以所述设定绘制帧率进行图像的绘制就能够满足该应用程序画面更新的需求。当然，还可以结合应用程序的运行场景为应用程序设置不同的设定绘制帧率。所述第二设定值可以根据具体需求进行设定，例如，将所述第二设定值设置为10。Wherein, the acquiring the real-time rendering frame rate of each currently running application program may include: acquiring the real-time rendering frame rate of each application program, and setting the set rendering frame rate corresponding to each application program in the whitelist. Correspondingly, the determining the target application program that satisfies the frame rate reduction condition according to the real-time rendering frame rate of each application program may include: taking each application program as the current application program; if the real-time rendering of the current application program If the difference between the frame rate and the corresponding set drawing frame rate is greater than a second set value, the current application program is determined as the target application program, and the second set value is greater than zero. Wherein, the white list includes the set drawing frame rate corresponding to each application, and the set drawing frame rate may be the drawing frame rate actually required by the application determined according to the empirical value, that is, the application program uses the setting Rendering images at a fixed rendering frame rate can meet the requirements for updating the screen of the application program. Of course, it is also possible to set different setting drawing frame rates for the application in combination with the running scene of the application. The second set value can be set according to specific requirements, for example, the second set value is set to 10.
步骤103、按照设定降帧率策略降低所述目标应用程序的绘制帧率。Step 103: Reduce the rendering frame rate of the target application program according to the set frame rate reduction strategy.
在确定了目标应用程序后，按照设定降帧率策略降低所述目标应用程序的帧率。其中，所述设定降帧率策略为预先设定的用于降低应用程序的绘制帧率的策略，可以包括将目标应用程序的当前实时绘制帧率降低10％，或者将目标应用程序的绘制帧率降低为设定值等。After the target application program is determined, the frame rate of the target application program is reduced according to the set frame rate reduction policy. Wherein, the setting frame rate reduction strategy is a preset strategy for reducing the frame rate of the application program, which may include reducing the current real-time frame rate of the target application program by 10%, or reducing the frame rate of the target application program by 10%. The frame rate is reduced to a set value, etc.
该步骤可以包括：将所述目标应用程序的绘制帧率设置为对应的设定绘制帧率。具体可以包括：确定目标应用程序当前所处的运行场景，根据所述运行场景确定所述目标应用程序在所述运行场景下对应的设定绘制帧率。This step may include: setting the rendering frame rate of the target application program to a corresponding set rendering frame rate. Specifically, it may include: determining the running scene where the target application program is currently located, and determining the corresponding set drawing frame rate of the target application program in the running scene according to the running scene.
该步骤可以包括：将用于合成图像的合成模块向所述目标应用程序提供垂直同步Vsync信号的频率设置为与所述设定绘制帧率相同。示例性的，当前一个目标应用程序的实时绘制帧率为60HZ，其对应的设定绘制帧率为40HZ，那么可将合成模块向该目标应用程序提供垂直同步Vsync信号的频率设置为40HZ，以控制该目标应用程序的绘制帧率更改为40HZ。This step may include: setting the frequency at which the synthesis module for synthesizing images provides the vertical synchronization Vsync signal to the target application program to be the same as the set rendering frame rate. Exemplarily, the real-time drawing frame rate of the current target application program is 60HZ, and its corresponding set drawing frame rate is 40HZ, then the frequency at which the synthesis module provides the vertical synchronization Vsync signal to the target application program can be set to 40HZ, in order to Control the drawing frame rate of the target application to 40HZ.
本实施例提供的移动终端帧率的控制方法，通过在确定移动终端的显示屏的刷新率大于第一设定值后，从当前运行的各个应用程序中确定满足设定降帧率条件的目标应用程序，按照设定降帧率策略降低所述目标应用程序的绘制帧率，可以降低移动终端的功耗。In the method for controlling the frame rate of the mobile terminal provided in this embodiment, after determining that the refresh rate of the display screen of the mobile terminal is greater than the first set value, determine the target that satisfies the set frame rate reduction condition from each currently running application program. The application program reduces the drawing frame rate of the target application program according to the set frame rate reduction policy, which can reduce the power consumption of the mobile terminal.
图4给出了本发明一个实施例提供的移动终端帧率的控制方法的流程图。如图4所示，本实施例提供的方法包括以下步骤：FIG. 4 shows a flow chart of a method for controlling the frame rate of a mobile terminal provided by an embodiment of the present invention. As shown in Figure 4, the method provided in this embodiment includes the following steps:
步骤201、确定移动终端的显示屏的刷新率大于第一设定值。Step 201. Determine that the refresh rate of the display screen of the mobile terminal is greater than a first set value.
步骤202、获取当前运行的各个应用程序的实时绘制帧率，以及设定白名单中所述各个应用程序对应的设定绘制帧率。Step 202 , acquiring the real-time rendering frame rate of each currently running application program, and setting the set rendering frame rate corresponding to each application program in the white list.
步骤203、根据所述各个应用程序的实时绘制帧率确定满足设定降帧率条件的目标应用程序。Step 203 , according to the real-time rendering frame rate of each application program, determine the target application program that satisfies the set frame rate reduction condition.
具体的，可以将实时绘制帧率与对应的设定绘制帧率的差值大于第二设定值的应用程序确定为目标应用程序，所述第二设定值大于0。示例性的，若第二设定值为10，当前应用程序的实时绘制帧率为80HZ，而获取到该当前应用程序对应的设定绘制帧率为50HZ，那么确定该当前应用程序满足设定降帧率条件。Specifically, an application program whose difference between the real-time rendering frame rate and the corresponding set rendering frame rate is greater than a second set value may be determined as the target application program, and the second set value is greater than zero. Exemplarily, if the second setting value is 10, the real-time drawing frame rate of the current application is 80HZ, and the set drawing frame rate corresponding to the current application is obtained as 50HZ, then it is determined that the current application meets the setting Frame rate drop condition.
步骤204、将所述目标应用程序的绘制帧率设置为对应的设定绘制帧率。Step 204: Set the rendering frame rate of the target application program to the corresponding set rendering frame rate.
如上述示例，可将所述当前应用程序的绘制帧率设置为50HZ。因为，当前应用程序实际所需的绘制帧率为50HZ，如果以实时的绘制帧率80HZ来进行绘制，只是多执行了一些不必要的绘制操作，并不会对当前应用的图像绘制带来明显的效果且增加了移动终端的功耗，本实施例通过将目标应用程序的绘制帧率设置为对应的绘制帧率，可以降低移动终端用于执行绘制操作的CPU和/或GPU的功耗。As in the above example, the rendering frame rate of the current application program may be set to 50HZ. Because the actual drawing frame rate required by the current application is 50HZ, if the drawing is performed at a real-time drawing frame rate of 80HZ, it will only perform some unnecessary drawing operations, which will not bring significant effects to the image drawing of the current application. effect and increase the power consumption of the mobile terminal, in this embodiment, by setting the drawing frame rate of the target application program to the corresponding drawing frame rate, the power consumption of the CPU and/or GPU for performing the drawing operation of the mobile terminal can be reduced.
本实施例提供的方法，通过在确定移动终端的显示屏的刷新率大于第一设定值后，获取当前运行的各个应用程序的实时绘制帧率，以及设定白名单中所述各个应用程序对应的设定绘制帧率，根据所述各个应用程序的实时绘制帧率确定满足设定降帧率条件的目标应用程序，将所述目标应用程序的绘制帧率设置为对应的设定绘制帧率，可以降低移动终端的功耗。In the method provided by this embodiment, after determining that the refresh rate of the display screen of the mobile terminal is greater than the first set value, obtaining the real-time drawing frame rate of each application program currently running, and setting each application program in the white list Corresponding to the set drawing frame rate, according to the real-time drawing frame rate of each application program, determine the target application program that meets the set frame rate reduction condition, and set the drawing frame rate of the target application program as the corresponding set drawing frame rate rate, which can reduce the power consumption of the mobile terminal.
图5为本发明一个实施例提供的移动终端帧率的控制装置的结构示意图，该装置可由软件和/或硬件实现，集成在移动终端中。如图5所示，该装置包括刷新率确定模块31、目标应用程序确定模块32和绘制帧率降低模块33。FIG. 5 is a schematic structural diagram of a device for controlling the frame rate of a mobile terminal provided by an embodiment of the present invention.
