图1为本申请实施例提供的一种动态调节终端的节能等级的方法的流程图，该方法可以由动态调节终端的节能等级的装置来执行，该装置可由软件和/或硬件实现，该装置可集成于电子设备中，该电子设备可以是智能手机、平板电脑及掌上游戏机等移动终端，该方法包括：
步骤110、获取当前显示的应用程序的应用标识。
示例性的，可以通过窗口管理服务（Window Manager Service，简称WMS）确定当前屏幕中显示的窗口。进而，获取该窗口中显示的应用程序的应用标识。其中，在Android系统中，采用窗口管理服务WMS对系统中的所有窗口进行管理，包括窗口的显示、隐藏或切换等。
应用标识是一个应用程序区别与其它应用程序的唯一标识，例如，应用标识可以是应用包名或进程名等。
可以理解的是，获取当前显示的应用程序的方法并不限于上述示例列举的方式，还可以通过安卓Android系统提供的进程管理服务确定前台运行的应用程序。例如，对于基于安卓Android系统的终端，可以通过Process.myPid()和RunningAppProcessInfo来确定前台运行的应用程序。
步骤120、根据所述应用标识查询设定的第一白名单，确定所述应用程序对应的第一节能等级，并获取所述第一节能等级对应的显示效果参数。
根据应用场景将终端的节能功能细分成多个节能等级。其中，应用场景可以包括预先设定的纯白场景、纯黑场景、图片灰阶过渡频繁的场景、动态场景、静态场景、透明场景或半透明场景等。应用场景还可以是预先设定的不同应用程序。不同节能等级具有不同的效果参数和省电程度。第一节能等级代表该多个节能等级中的任意一个等级。
节能等级可以为保真优化信号缩放FOSS（Fidelity Optimized Signal Scaling，保真优化信号缩放）等级，或者，内容适应背光控制CABC（Content Adaptive Brightness Control，内容适应背光控制）等级。
其中，FOSS是通过优化基于HVS(Human Visual System人类视觉系统)域的图像显示效果，来降低OLED屏幕的功耗。在一些实施例中，通过对不同显示内容的直方图进行重新计算，得出新的直方图，在屏幕上显示该新的直方图对应的显示内容，实现在保证显示效果的前提下降低一定的色阶值达到降功耗的目的。
例如，可以设置六个FOSS等级（即等级0至等级5），预先根据应用场景配置各个FOSS等级对应的显示效果参数，各个FOSS等级具有不同的效果参数和省电程度。其中，等级0表示FOSS功能关闭，不省电，等级1至等级5的省电程度逐渐增加，显示效果逐渐变差。
其中，CABC是通过对待显示的图片（input image）的图像进行统计分析，对待显示的图片的亮度进行调整，同时降低背光亮度，使显示屏采用降低后的背光亮度显示调整后的待显示图片。从而，在保证显示效果的基础上降低了功耗。CABC技术是LCD（Liquid Crystal Display，液晶显示屏）驱动IC中提供的一种背光驱动节电技术。其可以与SRE（Sunlight Readable Enhancement，阳光下视角增强技术，用于强光下提高显示对比度，增强可见度）协同使用。
可以理解的是，节能等级不限于本示例列举的数量，还可以根据实际需要设置节能等级的数量。例如，可以设置3个、4个或5个FOSS等级或CABC等级。
第一白名单中存储有应用标识和节能等级之间的关联关系。该第一白名单可以是在移动终端出厂前被预置于移动终端内的。例如，统计出用户常用的应用程序，作为设定的应用程序。针对不同型号、不同显示屏的终端分别适配上述设定的应用程序的节能等级。针对采用相同显示屏的同一型号的移动终端，分别采用上述多个节能等级中的一个节能等级对应的效果参数，处理该移动终端前台运行的应用程序的显示内容，根据均衡考虑显示效果和节能程度的方式确定该应用程序的节能等级。在该应用程序的节能等级确定后，将该应用程序与节能等级的对应关系存储于第一白名单。
在移动终端被激活后或被用户使用的过程中，可以在线更新该第一白名单。例如，在移动终端更新操作系统的版本时，可以同时更新终端内置的第一白名单。又如，移动终端厂商的服务器推送第一白名单更新消息至移动终端，以提示用户可以更新该第一白名单。
在确定当前显示的应用程序的应用标识后，可以根据该应用标识查询第一白名单，获取与该应用标识匹配的第一节能等级。然后，采用设定的接口访问存储有节能等级与显示效果参数的配置文件，获取该第一节能等级对应的显示效果参数。例如，在节能等级为FOSS等级时，调用设定的配置文件访问接口读取FOSS配置文件，获取第一FOSS等级对应的显示效果参数。
步骤130、根据所述第一节能等级设置终端的节能等级，并根据所述第一节能等级对应的显示效果参数对待显示画面进行处理。
将终端当前的节能等级设置为第一节能等级。将第一节能等级对应的显示效果参数传递给算法设置模块，以供画面调节模块根据所述算法设置模块中的显示效果参数，对所述当前场景模式对应的画面进行调节。其中，画面调节模块可以是FOSS模块或CABC模块。例如，将第一节能等级对应的显示效果参数传递给算法设置模块，以供FOSS模块根据所述算法设置模块中的显示效果参数对待显示画面的色阶进行调节，显示调节后的所述待显示画面。
可以理解的是，本实施例中对待显示画面的调节不限于对待显示画面的色阶进行调节，还可以调节画面的对比度、亮度等参数，或者综合调节色阶、对比度或亮度等。
在当前显示的应用程序变化时，可以通过节能等级服务层调整终端的节能等级。节能等级服务层是预置于终端内部的用于根据应用场景自动匹配最佳的效果和节能等级，使得节能等级可以在各个应用场景之间灵活切换的功能模块。例如，移动终端在出厂前被预置FOSS服务层。通过FOSS服务层提供的方法检测当前显示的应用程序，确定对应的节能等级，通过新确定的节能等级设置终端的节能等级，可以根据场景自动匹配最佳显示效果和省电程度的FOSS等级，使得FOSS等级在各个场景之间灵活切换，实现最佳显示效果和节省功耗的双重目的。
可以理解的是，若当前屏幕中同时显示至少两个应用程序时，分别确定各个应用程序对应的节能等级。然后，比较各个节能等级，根据低节能等级调整终端的节能等级，即根据低节能等级对应的参数调整待显示内容，将调整后的待显示内容发送至显示屏进行显示。还可以监测用户对该同时显示的至少两个应用程序的操作频率，根据操作频率最高的应用程序对应的节能等级调整终端的节能等级。
本实施例的技术方案，通过获取当前显示的应用程序的应用标识；根据所述应用标识查询设定的第一白名单，确定所述应用程序对应的第一节能等级，并获取所述第一节能等级对应的显示效果参数；根据所述第一节能等级设置终端的节能等级，并根据所述第一节能等级对应的显示效果参数对待显示画面进行处理，可以根据应用场景动态地调整终端的功耗。本申请的技术方案可以在降低终端的功耗的同时兼顾显示效果，延长了终端的续航时间。
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）或有机发光显示器（Organic Light Emitting Display，OLED）。
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。
另外，Android系统在将待显示画面传输给显示硬件的过程中引入了显示屏节能机制。图4是本申请实施例提供的一种基于FOSS的显示屏节能机制示意图。如图4所示，处理器310除将待显示画面的数据发送至显示屏330的驱动芯片320的图像分析器321之外，还可以将终端的当前FOSS等级对应的显示效果参数输入至第一算法设置模块322，进行存储。该待显示画面的数据即为需要在显示屏330中显示的图像数据，图像分析器321接收到处理器310发送的待显示画面的数据之后，可以进行分析，从而获知该图像的颜色、对比度、灰阶值等信息，以供后续处理。图像分析器321完成对待显示画面的数据的分析后，会将分析后的数据发送至FOSS模块323，由FOSS模块323采用设定的算法及第一算法设置模块322中存储的显示效果参数对分析后的数据进行处理。例如，对于色阶值符合显示效果参数的调整要求的像素点，进行调整，其余像素点可以不作灰阶亮度的调整。
在一些实施例中，预先声明FOSS等级对应显示效果参数，以等级1为例，预先声明等级1的等级号（mode id）及对应的应用场景，例如应用场景是视频场景。同时，设定该FOSS等级对应的第一参数，例如对比度、画面更新延迟计数、节电步长、节电输入参数及节电输出参数等。其中，对比度表示FOSS等级提供的对比度增强程度，取值范围是0至255，其中，0代表不进行对比度增强处理，255代表采用设定的最大值进行对比度增强处理。画面更新延迟计数代表算法调整画面的时间间隔，例如，若画面更新延迟计数的取值为3，则认为算法每隔3毫秒调整一帧画面。节电步长代表设定的色阶区间的边界，取值是0至255。步长越大，表示画面的色阶区间越多。节电输入参数代表显示画面包括的像素点的色阶值，取值范围是0至1023，其中，0代表黑色，1023代表白色。节电率输出参数代表按照设定的算法规则，将节电输入参数包含的像素点的色阶值映射到设定的灰阶亮度区间，取值范围是1至255，且由1至255省电程度逐渐降低，其中，1代表省电程度最高，255代表不省电。
示例性的，若节电步长为4，节电输入参数为32,48,700和788，节电输出参数为255,204,204和192，则以32,48,700和788为边界，将一幅色阶范围为0-1023的待显示图像划分为多个区间。将第一区间[0,32]内的色阶值映射为255（即待显示图像中色阶值0对应的省电程度为255，……,色阶值10对应的省电程度为255，……色阶值32对应的省电程度为255），将第二区间[33,48]内的色阶值映射为204，将第三区间[48,700]内的色阶值映射为204，将第四区间[701,788]内的色阶值映射为204。可替换的，还对待显示画面的对比度和灰阶亮度均进行调整等。
FOSS模块323可以将处理后的待显示画面的数据发送至显示屏330。其中，显示屏330为有机发光显示器（Organic Light Emitting Display，OLED）或AMOLED（Active Matrix/Organic Light Emitting Diode）屏幕。
图5是本申请实施例提供的一种基于CABC的显示屏节能机制示意图。如图5所示，处理器310除将待显示画面的数据发送至显示屏330的驱动芯片340的图像分析器341之外，还可以将终端的当前CABC等级对应的CABC参数输入至第二算法设置模块342，进行存储。该待显示画面的数据即为需要在显示屏330中显示的图像数据，图像分析器341接收到处理器310发送的待显示画面的数据之后，可以进行分析，从而获知该图像的颜色、对比度、灰阶值等信息，以供后续处理。图像分析器341完成对待显示画面的数据的分析后，会将分析后的数据发送至CABC模块343，由CABC模块343采用设定的算法及第二算法设置模块342中存储的CABC参数对分析后的数据进行处理。例如，可以是对待显示画面的灰阶亮度进行调整等。同时，CABC模块343输出脉冲信号给电源管理芯片350，电源管理芯片350通过预设的驱动算法控制背光灯驱动模块351的输出波形；通过该输出波形控制作为显示屏330的背光源的发光二极管360的亮度。例如，当移动终端的处理器310传送一张图片的数据到驱动芯片340，内容分析器341在计算并分析图片的数据后，通过CABC模块343依据设定算法自动的将该图片的灰阶亮度提高30%（此时图片变亮），再通过电源管理芯片350将背光亮度降低30%（此时图片变暗）。对于使用者来说，该图片的显示效果与未经过CABC模块343调整的图片的显示效果相差无几，但减少了30%的背光功耗。
图6是本申请实施例提供的另一种动态调节终端的节能等级的方法的流程图。所述方法包括：
步骤410、获取当前显示的应用程序的应用标识。
步骤420、判断该应用程序是否属于设定的第二白名单，若是，则执行步骤430，若否，则执行步骤470。
其中，第二白名单可以在移动终端出厂前预配置于移动终端内，还可以由用户根据自己的使用需求自行配置或更新。第二白名单内的应用程序可以包括视频应用、游戏或电子书等。第二白名单内的应用程序被赋予了节能等级调整的权限，即若第二白名单内的应用程序启动，且该应用程序满足预设的调整节能等级的条件，则可以将终端的节能等级动态调整至该应用程序对应的节能等级。其中，调整节能等级的条件为目标截图的数量超过设定的第三数量阈值。
示例性的，根据该应用标识查询设定的第二白名单，判断所述应用程序是否属于该第二白名单，若是，则执行步骤430，否则，执行步骤470。
步骤430、按照设定的周期对所述应用程序进行截屏处理，得到所述应用程序的截图。
通过截图线程按照设定的周期进行截屏处理，得到对应于应用程序画面的截图。其中，截屏处理可以理解为读取Frame Buffer（帧缓冲器）中的数据，将数据保存为一张图片。由于Frame Buffer提供接口将显示设备抽象为帧缓冲区，因此，将合成后的显示帧写入Frame Buffer，即可显示该显示帧。通过读取Frame Buffer中的数据，可以实现对应用程序进行截图。
可替换的，还可以采用view提供的方法进行应用程序内截屏。
可以理解的是，对于基于安卓Android系统的设备，截屏方法并不限于本实施例列举的方式。
步骤440、根据所述截图的直方图确定满足预设条件的目标截图的数量。
其中，直方图可以理解为是将数字图像中的所有像素按照灰阶值（灰度值或色阶值），统计其出现的频率得到的像素数量关于灰阶的分布情况示意图。
其中，将所述直方图中，像素数超过设定第一数量阈值的灰阶作为目标灰阶，预设条件为所述目标灰阶的数量超过设定的第二数量阈值。目标灰阶值的数量越多，表明图像的画面越细腻，对该图像对应的数据进行绘制（Render）、合成（Compose）及显示（Display）等一系列操作的耗电量通常较高。
示例性的，确定该截图的灰度直方图，若目标灰阶值的数量超过预先设定的第二数量阈值，则确定该截图为目标截图。采用上述方式确定设定时间长度内出现目标截图的数量。其中，第一数量阈值与第二数量阈值是根据实际需要预先设置好的。设置第一数量阈值的目的是减少噪声点对确定目标截图的操作产生干扰的情况。
步骤450、判断目标截图的数量超过设定的第三数量阈值，若是，则执行步骤460，否则执行步骤490。
将目标截图的数量与设定的第三数量阈值进行比较，若该目标截图超过设定的第三数量阈值，则执行步骤460，否则，执行步骤490。
步骤460、判定所述应用程序满足预设的调整节能等级的条件。
在目标截图的数量超过设定的第三数量阈值时，确定该应用程序满足预设的调整节能等级的条件。
步骤470、根据所述应用标识查询设定的第一白名单，确定所述应用程序对应的第一节能等级。
步骤480、根据所述第一节能等级设置终端的节能等级。
步骤490、不对终端的节能等级进行调整。
在目标截图未超过设定的第三数量阈值时，确定该应用程序不满足预设的调整节能等级的条件，此时无需对终端的节能等级进行调整。
本实施例的技术方案，通过为第二白名单内的应用程序设置调整节能等级的条件，可以使第二白名单内的应用程序的显示效果的优先级高于降功耗处理的优先级，即第二白名单内的应用程序在满足调整节能等级的条件时，才进行节能等级的动态调整，实现兼顾降低终端的功耗和显示效果的目的。
图7是本申请实施例提供的又一种动态调节终端的节能等级的方法的流程图。该方法包括：
步骤510、监测终端的状态参数。
其中，状态参数包括电池电量、电池温度、屏幕亮度中至少一项。
移动终端通过监听电池广播或屏幕广播的方式获取状态参数。示例性的，移动终端通过监听电池广播的状态信息的方式，获取电池电量和电池温度等参数。移动终端可以通过getScreenBrightness()函数获取屏幕亮度参数。
步骤520、判断该状态参数是否满足设定条件，若是，则执行步骤530，否则执行步骤510。
例如，将电池电量与设定的电量阈值进行比较，若该电池电量小于设定的电量阈值，则认为电池电量满足设定条件，执行步骤530，否则，执行步骤510。
又如，将电池温度与设定的温度阈值进行比较，若该电池温度超过设定的温度阈值，则认为电池温度满足设定条件，执行步骤530，否则，执行步骤510。
再如，将屏幕亮度（背光亮度）与设定的亮度阈值进行比较，若该屏幕亮度高于设定的亮度阈值，则认为屏幕亮度满足设定条件，执行步骤530，否则，执行步骤510。
可以理解的是，上述示例并不涵盖状态参数的全部，还可以是其它表征终端状态的参数。另外，上述示例中列举的参数还可以结合使用，通过上述任意2个参数结合来判断状态参数是否满足设定条件。或者，还可以采用上述3个参数结合来判断状态参数是否满足设定条件。
步骤530、执行获取当前显示的应用程序的应用标识的步骤。
步骤540、根据该应用标识查询设定的第一白名单，确定该应用程序对应的第一节能等级，并获取该第一节能等级对应的显示效果参数。
步骤550、根据该第一节能等级设置终端的节能等级，并根据该第一节能等级对应的显示效果参数对待显示画面进行处理。
本实施例的技术方案，增加预先判断终端当前状态是否满足执行动态调整节能等级的条件的步骤，即在终端的状态满足该预先设定的执行动态调整节能等级的条件时，才进行节能等级的动态调整，实现兼顾降低终端的功耗和显示效果的目的。
图8是本申请实施例提供的节能功能失效后恢复流程示意图。该方法包括：
步骤610、按照设定的周期获取终端的当前节能等级。
按照设定的周期，获取节能模块中存储的效果参数，根据该效果参数确定当前节能等级。其中，节能模块可以包括FOSS模块和CABC模块等。例如，FOSS模块通过自身存储的效果参数调整待显示画面的色阶值，在保证显示的效果的基础上减少一部分色阶，以降低终端的功耗。CABC模块通过效果参数对待显示的图片的对比度进行调整，同时降低背光亮度，在保证显示效果的基础上降低了功耗。
步骤620、根据该当前节能等级判断节能功能是否失效，若是，则执行步骤630，若否，则执行步骤640。
判断该当前节能等级是否是节能功能失效对应的节能等级，若是，则认为节能功能失效，否则，认为节能功能未失效。
示例性的，若预先设置当前移动终端包括六个FOSS等级，即等级0至等级5。其中，等级0表示FOSS功能关闭。若当前节能等级为等级0，则认为节能功能失效。
步骤630、重新启动节能功能，将节能等级配置为当前显示的应用程序对应的节能等级。
在一些实施例中，本步骤可以为重新启动FOSS功能，根据当前运行的应用程序确定对应的FOSS等级，通过FOSS服务层调用该FOSS等级对应的接口，获取该FOSS等级对应的效果参数。将该效果参数传递至FOSS模块，使FOSS模块根据该效果参数更新自身存储的参数。
步骤640、维持当前节能等级不变，直至检测到满足调整节能等级的条件时，动态调整节能等级。
其中，该调整节能等级的条件包括：当前屏幕显示的应用程序发生变化，且变化后的应用程序属于第一白名单，或者，第二白名单内的应用程序启动，且目标截图的数量超过设定的第三数量阈值。
本实施例的技术方案提供一种节能功能失效后恢复的方法，通过实时检测终端的节能功能是否失效；若是，则重新启动节能功能，将节能等级配置为当前显示的应用程序对应的节能等级，实现了在节能功能失效后，自动重启节能功能，可以达到降低功耗、延长续航时间的效果。
