请参阅图1，图1为本申请实施例提供的一种动态调节屏幕刷新率的方法的流程图，该方法可以由动态调节屏幕刷新率的装置执行，其中该装置可由软件和/或硬件实现，一般可集成在诸如移动终端的电子设备中。如图1所示，该方法包括：
步骤110、获取用户输入的操作指示，确定与所述操作指示关联的目标对象。
在一些实施例中，本申请实施例中的移动终端可为智能手机、智能手表、平板电脑、游戏机、个人数字助理和数字多媒体播放器等包含显示屏的电子设备。
其中，操作指示包括在屏幕上的触摸操作、设定的空间手势或设定的声音。该目标对象包括应用程序或图层等。
在一些实施例中，本步骤可以为获取用户作用于屏幕上的触摸操作，确定所述触摸操作对应的触点坐标，根据所述触点坐标确定所述触摸操作关联的目标对象。其中，触摸操作包括各种形式的与屏幕接触的操作，如点击、长按及滑动等。当用户触碰触摸屏时，触摸屏会检测到触摸信息，进而识别出用户的触摸操作。以电容式触摸屏为例，其通过感应人体触摸所产生的电容变化而判断触摸点。其具有两组信号线：驱动线与感应线，驱动线发射信号，感应线侦测电容值的变化。当手指触摸在金属层上时，由于人体电场的存在，手指和触摸屏表面形成一个耦合电容，对于高频电流来说，电容是直接导体，于是手指从接触点吸走一个很小的电流。影响了触摸点附近两个电极之间的耦合，从而改变了这两个电极之间的电容量。检测互电容大小时，驱动线方向的电极依次发出激励信号，感应线方向的所有电极同时接收信号，这样可以得到所有横向和纵向电极交汇点的电容值的变化，即整个触摸屏的二维平面的电容大小，根据触摸屏二维电容变化量数据，可以计算出每一个触摸点的坐标，因此屏上即使有多个触摸点，也能计算出每个触摸点的真实坐标。从而，可以确定包括触摸点的x坐标、y坐标、接触面的尺寸（包括长和宽等）以及触摸的手指数量等触摸信息，在识别到触摸信息后，通过input系统向上层上报坐标信息，便可利用触摸信息检测到屏幕的某处发生的触摸操作（可以包括触点坐标和触摸类型）。将触点坐标与屏幕中显示的界面进行匹配，确定触摸操作对应的目标对象。
请参阅图2，图2是本申请实施例提供的一种移动终端的屏幕示意图。由图2所示，屏幕显示的图像是101和广告102。用户拖动进度条103可以调整播放进度。若检测到用户拖动进度条103的操作，则认为用户当前着重关注视频图层，将包括该进度条103的视频图层作为目标对象。又如，若检测到打开弹幕功能的操作指示，则认为用户当前着重关注弹幕图层，将弹幕图层作为目标对象。
在一些实施例中，本步骤还可以为通过摄像头获取用户输入的手势信息，根据预先设置的手势与目标对象的关联关系确定所述手势信息对应的目标对象。其中，手势信息为预先设定的用于控制应用程序的姿态信息。例如，可以预先设置控制手势用于调节视频声音、打开弹幕功能或关闭广告等。
步骤120、获取所述目标对象对应的预设刷新率。
预先为目标对象设置对应的刷新率，以采用目标对象对应的刷新率将该待显示内容刷新至显示屏上进行显示，而不是采用屏幕的固定分辨率执行刷新操作。
在一些实施例中，可以采用刷新率表存储各个应用程序或图层的预设刷新率。例如，可以预先为视频图层（视频UI）和弹幕图层（用户UI）等图层设置不同的刷新率。在目标对象是弹幕图层时，查询该刷新率表确定弹幕图层对应的预设刷新率。还可以预先为视频应用、照片库应用或浏览器应用等设置刷新率。若浏览器应用被确定为目标对象，则根据浏览器应用的包名或进程名查询该刷新率表，可以确定与浏览器应用对应的预设刷新率。
步骤130、根据所述预设刷新率调整屏幕的刷新率。
将所确定的预设刷新率作为新的屏幕刷新率，显示屏根据该预设刷新率执行刷新操作。
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。请参阅图3，图3为本申请实施例提供的一种显示过程示意图。
首先，在应用（Application）层，每个应用程序（以下简称应用或APP）包含1个或多个图层，各个应用APP1、APP2…APPN按照自己的应用设计情况（一般由对应的安装包APK决定）各自单独执行图层绘制（Render）操作（即绘制图层上的图像），并在绘制操作处理完成后，各应用将所绘制的所有图层发送给执行图层合成操作的图层合成模块（Surface flinger）。
然后，在应用框架（Framework）层，所有图层（包括可见图层和不可见图层）组成一个图层列表，定义为ListAll。图层合成模块从ListAll中挑选出可见图层组成可见图层列表，定义为DisplayList。随后，图层合成模块从系统中三个可循环使用的帧缓冲器（Frame Buffer，简称BF或buffer）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，例如哪个图层应该置底、哪个图层应该置顶、哪个区域为可见区以及哪个区域为透明区等等，通过合成（Compose）操作，将DisplayList中包含的图层叠加在一起，得到最终的待显示画面。
最后，在内核（Kernel）层，可以将待显示画面传输给显示硬件（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（Liquid Crystal 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。请参阅图4，图4为本申请实施例提供的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，以控制每次图层绘制操作和图层合成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信号的频率目前常见为60Hz。如图2b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向各应用转发该第一个Vsync信号Vsync1，各应用响应用户在显示屏上的触摸滑动等操作，开始执行绘制操作；在各应用完成绘制操作后，得到各应用所绘制的多个图层。第二个Vsync信号Vsync2到达CPU后，CPU向图层合成模块转发该第二个Vsync信号Vsync2，图层合成模块开始执行图层合成操作，将各应用所绘制的多个图层进行合成，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。由上述描述可知，应用程序、图层合成模块和显示屏接收到的Vsync信号的频率是一致的，且是预先设置好的固定值。
在移动终端图层绘制、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。
其中，绘制帧率为图层绘制完成后，触发图层合成模块进行图层合成的帧率，可以理解为单位时间（例如，1秒钟）绘制的图层帧数。所述绘制帧率包括应用程序的绘制帧率和图层的绘制帧率。系统中运行的应用程序可能有多个，每个应用程序可能包括多个图层，例如，视频播放器应用程序下一般包括三个图层：一个显示视频内容的图层，可定义为U1；两个SurfaceView类型的图层，一个用于显示弹幕内容，可定义为U2，另一个用于显示用户界面（User Interface，UI）控件（如播放进度条、音量控制条以及各种控制按钮等）和广告，可定义为U3。所述应用程序的绘制帧率为应用程序单位时间内执行绘制操作的次数，其中，执行一次绘制操作时可能绘制了一个或者多个图层。所述图层的绘制帧率为同一编号或名称（如前面的U1、U2或U3）的图层单位时间内被触发绘制的次数。
合成帧率为把各个应用程序绘制的图层合成为一个待显示画面的帧率，可以理解为单位时间合成的画面帧数。
刷新率为移动终端显示屏画面刷新的帧率。一般，显示屏会以60Hz的刷新率刷新。
可通过降低用于绘制图层、合成图层或屏幕刷新的参考信号（如Vsync信号）的频率来实现降低图层绘制帧率、降低图层合成帧率或降低屏幕刷新率，且绘制图层、合成图层和屏幕刷新对应的Vsync信号的频率可以相同（如均由60Hz降为50Hz）也可以各不相同（如由60Hz分别降为50Hz、52Hz和54Hz）。也可通过变更图层绘制操作、图层合成操作和屏幕刷新操作对参考信号的响应机制来实现降低图层绘制帧率、降低图层合成帧率或降低屏幕刷新率。例如，接收到的第2n+1个信号响应，接收到的第2n个信号不响应；又如，以n个（如5个）信号为一组，每组中的第一类预设编号（如1,2,4,5）的信号响应，第二类预设编号（如4）的信号不响应。
本实施例的技术方案，通过获取用户输入的操作指示，确定与所述操作指示关联的目标对象；获取所述目标对象对应的预设刷新率；根据所述预设刷新率调整屏幕的刷新率，可以根据用户的操作动态的调整屏幕的刷新率。本申请实施例的技术方案可以解决终端的显示屏采用固定刷新率进行刷新的问题，实现根据用户当前操作的目标应用程序或目标图层等目标对象，有针对性地设置显示屏的刷新率，降低了显示屏的功耗，延长了终端的续航时间。
在上述技术方案的基础上，在根据所述预设刷新率调整屏幕的刷新率之后，优选的还包括：获取处于显示状态的应用程序或图层的绘制帧率和当前终端的合成帧率；在所述绘制帧率和/或合成帧率高于调整后的刷新率时，根据所述刷新率调整高于所述刷新率的绘制帧率和/或合成帧率。其中，该绘制帧率是处于显示状态的应用程序单位时间内执行绘制操作的次数，或者，该绘制帧率是处于显示状态的同一编号或名称（如前面的U1、U2或U3）的图层单位时间内被触发绘制的次数。该合成帧率是把当前处于显示状态的应用程序绘制的图层合成为一个待显示画面的帧率，可以理解为单位时间合成的画面帧数。该刷新率为移动终端的屏幕上显示画面刷新的帧率，可以理解为每秒刷新画面的帧数。例如，当前处于显示状态的应用程序包括APP1、APP2和APP3。其中，APP1的绘制帧率为50Hz，APP2的绘制帧率为54Hz，APP3的绘制帧率为56Hz。若通过本实施例的技术方案确定屏幕的刷新率为52Hz，则将高于该屏幕的刷新率的APP2的绘制帧率和APP3的绘制帧率降低至52Hz，可以进一步降低终端功耗。
请参阅图5，图5是本申请实施例提供的另一种动态调节屏幕刷新率的方法的流程图。如图5所示，该方法包括：
步骤310、获取用户输入的操作指示，确定与所述操作指示关联的目标对象。
示例性的，若用户先后开启弹幕功能和执行拖动进度条的操作，则认为弹幕图层和视频图层均为目标对象。
步骤320、判断目标对象的数量是否大于1，若是，则执行步骤330，否则执行步骤360。
步骤330、确定用户在设定时间长度内对所述目标对象的操作频率。
在检测到用户输入对目标对象的操作指示时，分别启动计时器和计数器，以确定用户在设定时间长度内对目标对象的操作频率。
例如，在检测到用户开启弹幕功能时，启动第一计时器，用于记录设定时间长度，同时将第一计数器的计数值加1。若随后检测到用户发布弹幕，判断弹幕发布时刻是否在该设定时间长度内，若是，则将第一计数器的计数值累加1，否则，维持第一计数器的计数值不变。根据设定时间长度内的第一计数器的计数值，可以确定用户在该设定时间长度内对弹幕图层的操作频率。
若用户在该设定时间长度内还执行了拖动进度条的操作，可以通过类似的方式确定用户在设定时间长度内对视频图层的操作频率。
可以理解的是，在目标对象是应用程序（APP）时，可以采用类似的方法确定用户对各个APP的操作频率。
步骤340、获取所述操作频率最高的所述目标对象对应的预设刷新率。
比较各个目标对象对应的操作频率，确定在设定时间长度内用户对其操作最频繁的一个目标对象，获取该目标对象对应的预设刷新率。
步骤350、根据所述预设刷新率调整屏幕的刷新率。
在目标对象的数量超过1个时，根据设定时间长度内用户操作最频繁的一个目标对象的预设刷新率调整屏幕的刷新率。
步骤360、获取所述目标对象对应的预设刷新率，转至执行步骤350。
在目标对象的数量为1个时，根据目标对象对应的预设刷新率调整屏幕的刷新率。
本申请实施例提供的动态调节屏幕刷新率的方法针对终端屏幕上显示多个图层或应用程序时，可以采用用户频繁操作的一个图层或应用程序的预设刷新率调整屏幕的刷新率，保证用户关注的图层或应用程序的显示效果的同时，达到了降低功耗的目的。
请参阅图6，图6是本申请实施例提供的又一种动态调节屏幕刷新率的方法的流程图。如图6所示，该方法包括：
步骤410、获取用户输入的操作指示，确定与所述操作指示关联的目标对象。
示例性的，若当前终端显示屏终同时显示视频应用和微信。用户在聊天时，在微信中输入聊天内容。即与用户输入的操作指示关联的目标对象是微信。
步骤420、获取所述目标对象对应的预设刷新率，将所述预设刷新率与设定的第一权值关联。
预先设置不同数量的应用程序或图层关联的权值集合。例如，在终端显示2个应用程序或图层时，设定作为目标对象的应用程序或图层的权值是0.8，另一个应用程序或图层的权值是0.2。在终端显示3个应用程序或图层时，设定作为目标对象的应用程序或图层的权值为0.6，剩余两个应用或图层可以根据预设的优先级关系，将优先级较高的应用程序或图层的权值设定为0.3，将优先级较低的应程序或图层的权值设定为0.1。可替换的，在终端显示3个应用程序或图层时，若设定目标对象的应用程序或图层的权值为0.6，剩余两个应用或图层的权值可均为0.2。可以理解的是，权值可以预先设定在移动终端内，还可以由用户自行设置。
在一些实施例中，本步骤可以为根据目标对象查询设定的刷新率表，确定与该目标对象对应的预设刷新率。根据当前显示的应用程序或图层可以确定对应的权值集合。将该权值集合中最大的一个权值作为第一权值，与该目标对象的刷新率进行关联。
步骤430、获取当前处于显示状态的该目标对象之外的应用程序或图层的预设刷新率，确定该目标对象之外的所述应用程序或图层的预设刷新率关联的设定的权值。
在一些实施例中，本步骤可以为根据当前处于显示状态的目标对象之外的应用程序或图层查询设定的刷新率表，确定当前显示的目标对象之外的应用程序或图层对应的预设刷新率。在当前显示的应用程序或图层对应的权值集合中，确定第一权值以外的权值。根据当前处于显示状态的目标对象之外的应用程序或图层的优先级顺序，将目标对象之外的当前显示的应用程序或图层对应的预设刷新率与第一权值以外的权值进行关联。例如，优先级较高的应用程序或图层对应的权值较高。
步骤440、计算当前显示的应用程序或图层的预设刷新率的加权值，将所述加权值作为屏幕的刷新率。
根据当前显示的应用程序或图层的预设刷新率及其对应的权值，计算当前显示的应用程序或图层的预设刷新率的加权值，将该加权值作为屏幕的刷新率。
例如，以当前终端显示屏终同时显示视频应用和微信为例，可以确定视频应用和微信关联的权值集合为（0.8,0.2），其中，第一权值为0.8。根据用户的操作指示可以确定当前用户关注的对象是微信，则为微信的预设刷（50Hz）新率与0.8关联，将视频应用（60Hz）的预设刷新率与0.2关联。从而，根据计算加权值的算法可以确定屏幕的刷新率为52Hz，低于屏幕的固定刷新率（60Hz）。
本申请实施例提供的动态调节屏幕刷新率的方法，在调节屏幕刷新率的过程中，以用户当前操作的应用程序或图层的预设刷新率为主要考虑因素，同时兼顾当前显示的其它应用程序或图层的预设刷新率，实现在保证用户关注的目标对象的显示效果的同时，兼顾其它应用程序或图层的显示效果，同时降低了终端功耗，延长了终端的续航时间。
