除非另有定义，本文所使用的所有的技术和科学术语与属于本申请中的技术领域的技术人员通常理解的含义相同。本申请的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在于限制本申请。应理解，本申请中除非另有说明，“/”表示或的意思。例如，A/B可以表示A或B。本申请中的“和/或”仅仅是一种描述关联对象的关联关系，表示可以存在三种关系。例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B三种情况。“至少一个”是指一个或者多个。“多个”是指两个或多于两个。例如，a、b或c中的至少一个，可以表示：a，b，c，a和b，a和c，b和c，a、b和c七种情况。
本申请实施例中的用户界面(User Interface，UI)，是应用程序或操作系统与用户之间进行交互和信息交换的介质接口，可实现信息的内部形式与用户可以接受形式之间的转换。应用程序的用户界面是通过JAVA、可扩展标记语言(extensible markup language，XML)等特定计算机语言编写的源代码，界面源代码在电子设备上经过解析、渲染，最终呈现为用户可以识别的内容，比如图片、文字、按钮等控件。控件(control)，是用户界面的基本元素，典型的控件有按钮(button)、小工具(widget)、工具栏(toolbar)、菜单栏(menu bar)、文本框(text box)、滚动条(scrollbar)、图片(image)和文本(text)。界面中的控件的属性和内容是通过标签或者节点来定义的，比如XML通过<Textview>、<ImgView>、<VideoView>等节点来规定界面所包含的控件。一个节点对应界面中一个控件或属性，节点经过解析和渲染之后呈现为用户可视的内容。此外，很多应用程序，比如混合应用(hybrid application)的界面中通常还包含有网页。网页，也称为页面，可以理解为内嵌在应用程序界面中的一个特殊的控件，网页是通过特定计算机语言编写的源代码，例如超文本标记语言(hyper text markup language，HTML)，层叠样式表(cascading style sheets，CSS)，JAVA脚本(JavaScript，JS)等，网页源代码可以由浏览器或与浏览器功能类似的网页显示组件加载和显示为用户可识别的内容。网页所包含的具体内容也是通过网页源代码中的标签或者节点来定义的，比如HTML通过<p>、<img>、<video>、<canvas>来定义网页的元素和属性。
用户界面常用的表现形式是图形用户界面(graphic user interface，GUI)，是指采用图形方式显示的与计算机操作相关的用户界面。它可以是在电子设备的显示屏中显示的一个图标、窗口、控件等界面元素。
在不冲突的情况下，下述的实施例及实施例中的特征可以相互组合。
为了更好地理解本申请实施例提供的显示屏亮度调整方法，下面首先对本申请显示屏亮度调整方法的应用场景进行描述。
参阅图1A所示，为本申请实施例提供的显示屏亮度示意图。在显示屏亮屏时，电子设备的环境光传感器可以采集环境光亮度，并基于环境光亮度设置合适的显示屏亮度。例如，在环境光亮度为5lux(勒克斯)时，显示屏亮度设置为18阶，在环境光亮度为20lux时，显示屏亮度设置为58阶。
参阅图1B所示，为本申请实施例提供的显示屏亮度调整界面的示意图。由于不同用户对电子设备自动设置的显示屏亮度的喜好程度不一致，或同一用户在不同环境光亮度下对电子设备自动设置的显示屏亮度的喜好程度不一致，用户可以在显示屏亮度调整界面上拖动亮度条，从而在电子设备自动设置的显示屏亮度的基础上，手动调整显示屏亮度，使得显示屏亮度适应个人需求。例如，如图1A所示，在环境光亮度为50lux时，显示屏亮度设置为87.5阶，用户手动调整后的显示屏亮度为107.98阶，在环境光亮度为100lux时，显示屏亮度设置为95阶，用户手动调整后的显示屏亮度为120.6阶。
参阅图1C所示，为本申请实施例提供的默认亮度曲线和手动调整后的亮度曲线的示意图。在不同的环境光亮度下，电子设备的默认亮度曲线L1与用户手动调整后的亮度曲线L2存在差异。
参阅图2所示，为现有技术中显示屏亮度的调整架构示意图。用户在手动调整显示屏亮度后，在使用环境不变(即环境光亮度不变)的情况下，电子设备经过灭屏再亮屏，显示屏亮度保持不变，即仍然保持用户调整后的显示屏亮度。在使用环境产生变化(即环境光亮度产生变化)的情况下，电子设备经过灭屏再亮屏，可以基于变化后的环境光亮度对显示屏亮度进行适应性调整。例如，在环境光亮度增大时，提高用户调整后的显示屏亮度，在环境光亮度减小时，减小用户调整后的显示屏亮度。
然而，用户可能不接受对于不同环境光亮度下电子设备自适应调整的显示屏亮度，如此，在使用环境产生变化时，电子设备在灭屏并亮屏后自适应调整的显示屏亮度不符合用户需求，导致用户无法正常观看显示屏内容，从而影响用户体验。此外，用户可能因误操作而手动调整了显示屏亮度，如此，无论在使用环境不变时电子设备保持手动调整后的显示屏亮度，以及使用环境变化时电子设备自适应调整的显示屏亮度都不符合用户需求，导致用户无法正常观看显示屏内容，从而影响用户体验。
参阅图3所示，为本申请实施例提供的电子设备的软件架构图。分层架构将软件分成若干个层，每一层都有清晰的角色和分工。层与层之间通过软件接口通信。例如，将安卓系统分为四层，从上至下分别为应用程序层101，框架层102，安卓运行时(Android runtime)和系统库103，硬件抽象层104，内核层105以及硬件层106。
应用程序层可以包括一系列应用程序包。例如，应用程序包可以包括相机，图库，日历，通话，地图，导航，WLAN，蓝牙，音乐，视频，短信息，设备控制服务等应用程序。
框架层为应用程序层的应用程序提供应用编程接口(Application Programming Interface，API)和编程框架。应用程序框架层包括一些预先定义的函数。例如，应用程序框架层可以包括窗口管理器，内容提供器，视图系统，电话管理器，资源管理器，通知管理器等。
其中，窗口管理器用于管理窗口程序。窗口管理器可以获取显示屏大小，判断是否有状态栏，锁定屏幕，截取屏幕等。内容提供器用来存放和获取数据，并使这些数据可以被应用程序访问。所述数据可以包括视频，图像，音频，拨打和接听的电话，浏览历史和书签，电话簿等。视图系统包括可视控件，例如显示文字的控件，显示图片的控件等。视图系统可用于构建应用程序。显示界面可以由一个或多个视图组成的。例如，包括短信通知图标的显示界面，可以包括显示文字的视图以及显示图片的视图。电话管理器用于提供电子设备的通信功能。例如通话状态的管理(包括接通，挂断等)。资源管理器为应用程序提供各种资源，比如本地化字符串，图标，图片，布局文件，视频文件等。通知管理器使应用程序可以在状态栏中显示通知信息，可以用于传达告知类型的消息，可以短暂停留后自动消失，无需用户交互。比如通知管理器被用于告知下载完成，消息提醒等。通知管理器还可以是以图表或者滚动条文本形式出现在系统顶部状态栏的通知，例如后台运行的应用程序的通知，还可以是以对话窗口形式出现在屏幕上的通知。例如在状态栏提示文本信息，发出提示音，电子设备振动，指示灯闪烁等。
Android Runtime包括核心库和虚拟机。Android runtime负责安卓系统的调度和管理。核心库包含两部分：一部分是java语言需要调用的功能函数，另一部分是安卓的核心库。
应用程序层和框架层运行在虚拟机中。虚拟机将应用程序层和框架层的java文件执行为二进制文件。虚拟机用于执行对象生命周期的管理，堆栈管理，线程管理，安全和异常的管理，以及垃圾回收等功能。
系统库可以包括多个功能模块。例如，表面管理器(surface manager)，媒体库(Media Libraries)，三维图形处理库(例如：OpenGL ES)，2D图形引擎(例如SGL)等。
其中，表面管理器用于对显示子系统进行管理，并且为多个应用程序提供了2D和3D图层的融合。媒体库支持多种常用的音频，视频格式回放和录制，以及静态图像文件等。媒体库可以支持多种音视频编码格式，例如:MPEG4，H.264，MP3，AAC，AMR，JPG，PNG等。三维图形处理库用于实现三维图形绘图，图像渲染，合成，和图层处理等。2D图形引擎是2D绘图的绘图引擎。
硬件抽象层运行于用户空间，对内核层驱动进行封装，向上层提供调用接口。
内核层是硬件和软件之间的层。内核层至少包含显示驱动，摄像头驱动，音频驱动，传感器驱动。
内核层是电子设备的操作系统的核心，是基于硬件的第一层软件扩充，提供操作系统最基本的功能，是操作系统工作的基础，负责管理系统的进程、内存、设备驱动程序、文件和网络系统，决定了系统的性能和稳定性。例如，内核可以决定一个应用程序对某部分硬件的操作时间。
内核层包括与硬件紧密相关的程序，例如中断处理程序、设备驱动程序等，还包括基本的、公共的、运行频率较高的模块，例如时钟管理模块、进程调度模块等，还包括关键性的数据结构。内核层可以设置于处理器中，或固化在内部存储器。

在本申请的一实施例中，设置的显示屏亮度为显示屏的背光亮度等级，单位是阶。响应于自动亮度设置指令，设置显示屏亮度的细化流程包括：基于电子设备的使用场景产生的自动亮度设置指令，设置显示屏亮度。
在本申请的一实施例中，基于电子设备的使用场景产生的自动亮度设置指令，设置显示屏亮度的细化流程如图5所示，具体包括：
S501，判断电子设备的使用场景是否为预设的第一使用场景或第二使用场景。
在本申请的一实施例中，判断电子设备的使用场景是否为预设的第一使用场景或第二使用场景由应用程序层执行。
电子设备至少预设有第一使用场景和第二使用场景。预设的第一使用场景包括，但不局限于电子设备运行视频应用程序、电子设备运行二维码软件及电子设备处于前置摄像头补光状态。具体地，电子设备运行二维码软件为电子设备的显示屏正在显示二维码。电子设备处于前置摄像头补光状态为电子设备正在使用前置摄像头进行拍摄且环境光亮度小于预设亮度。可选地，预设亮度为20lux。预设的第二使用场景包括，但不局限于电子设备处于热限制状态、电子设备处于前置摄像头亮度限制状态、电子设备处于低电量模式、电子设备处于人脸解锁状态、电子设备处于场景识别状态。具体地，电子设备处于热限制状态为电子设备的壳体温度或主板温度大于或等于阈值温度。可选地，阈值温度为50℃。电子设备处于前置摄像头亮度限制状态为电子设备正在使用前置摄像头进行拍摄。电子设备处于低电量模式为电子设备的电量小于或等于预设百分比。可选地，预设百分比为20％。电子设备处于人脸解锁状态为电子设备亮屏且处于锁定状态进行人脸解锁的状态。电子设备处于场景识别状态为电子设备开启后置摄像头进行拍摄以识别目标物件的状态。

在本申请的一实施例中，若确定电子设备的使用场景为预设的第一使用场景，传递自动亮度设置指令至框架层的电源(power)框架(例如，如图3所示，框架层102包括电源框架1021)，由电源框架将第一亮度范围内的亮度值确定为显示屏亮度。
可选地，第一亮度范围为0-1。若确定电子设备的使用场景为预设的第一使用场景，可以将第一亮度范围内的任一亮度值确定为显示屏亮度，例如，将第一亮度范围0-1内的亮度值1确定为显示屏亮度。
需要说明的是，在第一使用场景下，例如电子设备正在播放视频、正在显示二维码或在较低的环境光亮度下使用前置摄像头进行拍照时，需要设置较高或最高的显示屏亮度，所需的显示屏亮度阶数较小，因此基于较小的亮度范围获取显示屏亮度。
S503，若确定电子设备的使用场景为预设的第二使用场景，基于第二亮度范围的亮度值确定显示屏亮度。
在本申请的一实施例中，若确定电子设备的使用场景为预设的第二使用场景，传递自动亮度设置指令至框架层的电源框架，由电源框架基于第二亮度范围确定显示屏亮度。

例如，在电子设备正在显示二维码时，确定的显示屏亮度为第一亮度范围内的亮度值1，所述显示屏亮度映射得到第二亮度范围内的亮度值255，再映射得到第三亮度范围内的亮度值10000，作为第三亮度范围内的显示屏亮度。
例如，在电子设备处于低电量模式时，确定的显示屏亮度为第二亮度范围内的亮度值25，所述显示屏亮度映射得到第三亮度范围内的子亮度范围为900-1200，然 后可以确定所述子亮度范围900-1200内的任一亮度值为第三亮度范围内的显示屏亮度。
