以下实施例将以图1和图2所示的手机100为例对本申请的技术方案进行详细介绍。以下实施例中，以手机100中的第三方相机应用为例，其中第三方相机应用例如可以是美颜相机、萌拍等应用。
本申请中，手机100可以根据当前的场景判断是否需要升起或下降摄像头，而不是单纯在第三方相机应用启动的情况下，升起摄像头，在第三方相机应用退出的情况下，收回摄像头。在一些实施例中，当前的场景可以包括：手机100将第三方相机应用从前台运行切换到后台运行；或者，手机100将第三方相机应用从后台运行切换到前台运行；或者，手机100在第三方相机应用的显示界面中进行分辨率切换、前后置摄像头的切换；或者，手机100中第三方相机应用的显示界面由图像拍摄模式切换到视频录制模式；或者，手机100在显示第三方相机应用的显示界面时，检测到用于灭屏的操作而熄灭显示屏等场景。
图3中的(a)示出了本申请一实施例提供的GUI的示意图，该GUI可以称为主界面301。主界面301中可以包括多个应用的图标。其中，包括第三方相机应用(比如美图秀秀)的图标302。手机100检测到针对图标302的操作时，显示另一GUI，参见图3中的(b)所示，该GUI可以称为第三方相机应用的显示界面303。该显示界面303中可以包括一个或多个控件。比如，包括“超清人像拍摄”控件304和“图片精修”控件305，以及相机控件306。手机100检测到针对相机控件306的操作时，显示取景界面307，如图3中的(c)所示，取景界面307中包括预览图像，以及一个或多个控件。
在一些实施例中，手机100检测到针对主界面301中的图标302的操作时，可以升起前置摄像头，并启动该前置摄像头。在另一些实施例中，手机100检测到针对第三方相机应用的显示界面303中的相机控件306的操作时，可以升起前置摄像头，并启动该前置摄像头，在取景界面307中显示该前置摄像头采集的图像，即预览图像。
场景1：第三方相机应用在前台运行。
以图3中的(c)为例，手机100升起前置摄像头，即取景界面307中显示的是前置摄像头采集的图像，后置摄像头处于关闭状态。在一些实施例中，手机100在前台运行第三方相机应用的过程中，可以保持前置摄像头一直处于升起状态，直到第三方相机应用切换到后台运行，收回前置摄像头。
示例1：以图3中的(c)为例，手机100检测针对关闭控件308的操作，关闭取景界面，返回图3中的(b)所示的界面303。该过程中，手机100可以继续保持前置摄像头升起状态。因为，用户控制手机100返回第三方相机应用的主页303，可能是想要重新选择其它的拍摄方式，比如选择“美妆拍摄”等。因此，这种情况下，手机100可以不收回前置摄像头，以避免前置摄像头的频繁升降。
示例2：以图3中的(c)为例，手机100检测到针对分辨率切换控件309的操作，手机100将当前的预览图像的分辨率切换到目标分辨率，比如从1:1切换到9:16。该过程中，手机100可以继续保持前置摄像头处于升起状态。
示例3；以图3中的(c)为例，手机100检测针对关闭控件308的操作，关闭取景界面，返回图3中的(b)所示的界面303。手机100检测到针对界面303中“图片精修”控件305的操作时，手机100进入修图模式，对手机100中存储的图像进行修图。该过程中，手机100也可以继续保持前置摄像头处于升起状态。
示例4：手机100关闭第三方相机应用的取景界面(取景界面中包括预览图像)，但是仍然在前台运行(比如，显示第三方相机应用的非取景界面的其它界面)时，可以等待预设时长，若手机100在该时长内未再次打开取景界面，则收回前置摄像头。
举例来说，以图3中的(c)为例，手机100检测针对关闭控件308的操作，关闭取景界面，返回图3中的(b)所示的界面303。假设手机100停留在界面303的时长超过预设时长，则收回前置摄像头；或者，手机100检测到针对界面303中的“图片精修”控件305的操作，进入修图模式，修图模式中无需使用前置摄像头，则收回前置摄像头。当手机100再次打开取景界面时，可以再次升起前置摄像头。需要说明的是，本申请实施例中，“打开”取景界面是指在前台显示取景界面。
示例5：
参见图4中的(a)所示，手机100启动第三方相机应用，升起前置摄像头，显示第三方相机应用的取景界面401，该取景界面401中包括前置摄像头采集的图像。当手机100检测到针对取景界面401中的摄像头切换控件402的操作时，启动后置摄像头，参见图4中的(b)所示，取景界面403中显示后置摄像头采集的图像。在一些实施例中，手机100启动后置摄像头后，可以不下降前置摄像头。当手机100确定满足一定条件时，再下降前置摄像头。比如，手机100检测到第三方相机应用从前台切换到后台时，下降前置摄像头。再比如，第三方相机应用在前台运行，但是较长时间未从后置摄像头切换到前置摄像头，则下降前置摄像头。再比如，手机100启动后置摄像头后，可以输出提示信息，该提示信息用于提示用户是否下降前置摄像头，若手机100接收到下降前置摄像头的确认指令后，下降前置摄像头。
举例来说，以图4中的(b)为例，取景界面403显示后置摄像头采集的图像，手机100中前置摄像头处于升起状态。手机100检测到针对关闭控件404的操作，返回第三方相机应用的上一级界面，比如第三方相机应用的主页，例如类似于图3中的(b)所示的主页303，手机100仍然保持前置摄像头升起状态。再例如，继续以图4中的(b)为例，取景界面403 显示后置摄像头采集的图像，手机100中前置摄像头处于升起状态。手机100检测到针对分辨率切换控件405的操作，切换预览图像的分辨率，手机100仍然保持前置摄像头处于升起状态。
示例6：
参见图5中的(a)所示，手机100启动第三方相机应用，升起前置摄像头，显示第三方相机应用的取景界面501，该取景界面501中包括前置摄像头采集的图像。当手机100检测到针对取景界面501中的视频控件502的操作时，由图像拍摄模式切换为视频录制模式，参见图5中的(b)所示。在一些实施例中，手机100由图像拍摄模式改变为视频录制模式后，可以不下降前置摄像头。
应理解，上述各个示例的技术特征可以组合使用。例如，示例5和示例6可以组合使用。示例6中手机100从图像拍摄模式改变为视频录制模式之后，保持前置摄像头升起状态。当手机100确定满足一定条件时，再下降前置摄像头。比如，手机100检测到第三方相机应用从前台切换到后台时，下降前置摄像头。再比如，手机100进入视频录制模式之后，检测到针对取景界面中的摄像头切换控件的操作，启动后置摄像头，视频录制模式下取景界面中显示后置摄像头采集的图像。手机100确定预设时长内，未从后置摄像头切换到前置摄像头，则下降前置摄像头。再比如，手机100进入视频录制模式后，检测到针对取景界面中的摄像头切换控件的操作，启动后置摄像头，可以输出提示信息，该提示信息用于提示用户是否下降前置摄像头，若手机100接收到下降前置摄像头的确认指令后，下降前置摄像头。
再例如，上述示例6和示例2可以组合使用，示例6中手机100进入视频录制模式后，保持前置摄像头处于升起状态。手机100检测到针对视频录制模式下取景界面中的分辨率切换控件的操作，切换预览图像的分辨率。该过程中，手机100可以保持前置摄像头处于升起状态。
在场景1所示的实施例中，手机100在前台运行第三方相机应用的过程中，不会频繁的升降前置摄像头，有助于提升用户体验。
场景2，第三方相机应用从前台切换到后台运行。
在一些实施例中，以图4中的(a)为例，手机100显示第三方相机应用的取景界面401，当手机100检测到第三方相机应用切换到后台运行的操作(比如，检测到返回主界面的操作，或者将取景界面401切换成其他应用的显示界面的操作)时，收回前置摄像头。或者，手机100检测到第三方相机应用切换到后台运行时，等待一定的时长，当手机100确定在该时长内第三方相机应用未切换到前台，手机100收回前置摄像头。在该实施例中，手机100确定第三方相机应用从前台切换到后台运行时，可以关闭后置摄像头。
示例1：
以图3中的(c)为例，手机100启动第三方相机应用，升起前置摄像头，显示取景界面307，取景界面307中包括前置摄像头采集的图像。手机100检测到用于返回主界面的操作后，显示主界面，比如可以是图3中的(a)所示的主界面301，此时第三方相机应用在后台运行，这种情况下，手机100可以收回前置摄像头；或者，手机100显示主界面后，可以等待一定的时长，当手机100确定在该时长内第三方相机应用未再次切到前台运行，手机100收回前置摄像头。
示例2：
参见图6中的(a)所示，手机100启动第三方相机应用，升起前置摄像头，显示取景界面601，取景界面601中显示前置摄像头采集的图像。手机100中的微信应用收到新消息，在状态栏中显示新消息，手机100检测到针对状态栏的操作(比如，点击操作)，显示如图6中的(b)所示的微信应用的显示界面，此时第三方相机应用在后台运行，手机100可以收回前置摄像头；或者，手机100显示微信应用的显示界面后，可以等待一定时长，当手机100确定该时长内第三方相机应用未再次切换到前台，手机100收回前置摄像头。
示例3：
参见图7中的(a)所示，手机100启动第三方相机应用，升起前置摄像头，显示取景界面701。取景界面701中包括前置摄像头采集的图像。此时，手机100检测到灭屏的操作，比如针对电源键的操作，熄灭显示屏，如图7中的(b)所示。一种可能的情况为，手机100检测到屏幕熄灭之后，立即收回前置摄像头。另一种可能的情况为，手机100检测到屏幕熄灭之后，可以等待预设时长，在预设时长之后再收回前置摄像头。例如，手机100确定该预设时长内，未重新点亮手机，或者未重新点亮手机并重新进入第三方相机应用的取景界面，则收回前置摄像头。
在场景2所示的实施例中，手机100可以在用户不使用前置摄像头的情况下，收回前置摄像头，以节省资源。比如，手机100将第三方相机应用从前台切换到后台，可以立即收回前置摄像头，也可以等待预设时长，若该预设时长内所述第三方相机应用未切回到前台，则收回前置摄像头。
场景3：第三方相机应用从后台切换到前台。
在一些实施例中，手机100前台运行第三方相机应用时，升起前置摄像头。当手机100将第三方相机应用从前台切换到后台时，收回前置摄像头。当手机100将第三方相机应用从后台切换的前台时，再次升起前置摄像头。
示例1：
参见图8中的(a)所示，手机100启动第三方相机应用，升起前置摄像头，显示取景界面801，取景界面801中包括前置摄像头采集的图像。手机100检测到将第三方相机应用切换到后台运行的操作，比如返回主界面802，手机100收回前置摄像头，参见图8中的(b)所示。手机100检测到将第三方相机应用切换到前台运行的操作(例如，针对主界面802中的第三方相机应用的图标的点击操作)，再次升起前置摄像头，显示如图8中的(c)所示的界面。
在场景3所示的实施例中，手机100可以根据当前场景决定前置摄像头的升降。比如，比如，手机100将第三方相机应用从前台切换到后台，可以收回前置摄像头。当手机100将所述第三方相机应用从后台切换到前台，可以再次升起前置摄像头。
图9示出了本申请一实施例提供的手机100的软件架构的示意图。如图9所示，手机100的软件架构自下而上主要包含5层：内核(kernel)层、硬件抽象层(hardware abstraction layer，HAL)、安卓运行时(Android runtime)和系统库、框架(framework，FWK)层以及应用(application)层。
其中，应用层包括多个应用，比如，应用1到应用n，n为大于等于2的整数。比如，系统相机、第三方相机应用，抖音、微信/QQ等。
框架层为应用层的应用程序提供应用编程接口(application programming interface，API)和编程框架。框架层可以包括一些预先定义的函数。例如，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。
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手机100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。
此外，如图9所示，框架层还可以包括：升降系统和升降管理服务模块。其中，升降系统可以是应用层中的第三方相机应用和框架层中的升降管理服务模块之间的桥梁。比如，升降系统可以接收第三方相机应用发送的升起或下降摄像头指令，然后将该指令发送给升降管理服务模块。升降管理服务模块，用于判断是否需要升起或下降摄像头。在一些实施例中，升降管理服务模块可以是升降系统中的一部分，或者独立于升降系统。若升降管理服务模块确定需要升起摄像头，则通过HAL层控制摄像头升起；或者，升降管理服务模块确定需要下降摄像头，则通过HAL层控制摄像头收回。
在一些实施例中，升降管理服务模块可以监听第三方相机应用的活动(activity)，比如，监听第三方相机应用的activity是否变化。升降管理服务模块可以根据activity的变化情况决定升起或下降摄像头。具体内容将在后文介绍。
需要说明的是，activity可以是一个应用产生的交互界面。比如，第三方相机应用启动后，可以创建activity，即交互界面，交互界面可以包括取景界面。升降管理服务模块可以监听第三方相机应用的activity的生命周期。其中，activity的生命周期可以是一个应用创建activity开始，直到关闭activity的周期/时长。继续以第三方相机应用为例，升降管理服务模块监听第三方相机应用的activity的生命周期可以包括监听该activity的任何变化(比如，从前台切换后台，或者，从后台切换到前台等)，然后根据activity的变化情况确定是否升起或下降摄像头。
在另一些实施例中，每个应用可以对应一个或多个activity。为了方便区分哪一个应用的activity，每个activity可以设置activity名称。升降管理服务模块监听到activity发生变化时，可以判断该activity是哪一个应用的，如果是第三方相机应用的，则根据该activity的变化情况决定升起或下降摄像头。
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。应用程序层和应用程序框架层运行在虚拟机中。虚拟机将应用程序层和应用程序框架 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。
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。
HAL层可以包括一些调用接口，该调用接口可以将内核层中复杂的驱动或接口统一化。例如，HAL层可以包括音视频接口、GPS接口、通话接口(radio interface layer，RIL)、WIFI接口等。另外，HAL层还可以作为框架层和内核层的桥梁，比如，HAL层可以接收框架层中升降管理服务模块发送的弹出或收回摄像头的命令，然后HAL层通过内核层控制摄像头弹出或收回。
内核层包括触摸传感器驱动、显示驱动、摄像头驱动等。其中，触摸传感器驱动用于将触摸传感器检测到的触摸操作上报框架层，显示驱动用于驱动显示屏显示内容，摄像头驱动用于打开或关闭摄像头等。
需要说明的是，图1是本申请实施例提供的手机100的硬件架构，图9是本申请实施例提供的手机100的软件架构，图9中的软件架构对应的软件程序和/或模块存储在内部存储器121中，处理器110(比如，NPU或CPU)运行内部存储器121中存储的软件程序和/或模块以执行相应的摄像头的升降过程。
参见图10所示，为手机100通过图8所示的软件架构实现第三方相机应用从后台切换到前台，或者从前台切换到后台时对摄像头的处理过程。如图10所示，该过程可以包括：
1001：第三方相机应用向升降系统发送第一指令，该第一指令用于指示打开前置摄像头。
在1001之前，手机100还可以包括其它过程，比如，触摸传感器驱动将检测到的输入事件(比如检测到在主界面中的点击操作、点击时间、位置坐标等)发送给框架层。框架层中可以存储有当前显示界面(即主界面)中每个触摸区域的坐标，所以框架层可以将输入事件中点击操作的位置坐标和存储的触摸区域的坐标比对，确定输入事件对应的触摸区域，然后确定该触摸区域内的显示内容，假设该触摸区域内是第三方相机应用的图标，则框架层可以确定该输入事件对应第三方相机应用，并上报应用层中的第三方相机应用。第三方相机应用接收到输入事件后，向升降系统发送打开前置摄像头的指令。
1002：升降系统将第一指令发送给升降管理服务模块。
如前述内容可知，升降系统没有直接向HAL层发送打开前置摄像头的指令，而是向升降管理服务模块发送打开前置摄像头的指令，由升降管理服务模块决定是否升降摄像头。
1003：升降管理服务模块根据摄像头状态记录表确定前置摄像头当前处于收回状态。
在一些实施例中，升降管理服务模块可以记录每个摄像头的状态，比如，每个摄像头处于开启或关闭状态，和/或每个摄像头处于升起或收回状态。作为一种示例，参见表1，为本申请一实施例提供的升降管理服务模块记录的每个摄像头的状态记录表的示例。
摄像头 收回/升起 开启/关闭
前置摄像头 收回 关闭
后置摄像头 NA 关闭
表1
举例来说，升降管理服务模块可以基于表1确定前置摄像头目前处于收回状态，那么升降管理服务模块可以向HAL层发送第二指令，该第二指令用于指示升起/弹出前置摄像头。应理解，后置摄像头的“NA”可以用于指示后置摄像头无法升降，是固定设置在手机100的背面的。
1004：升降管理服务模块向HAL层发送弹出命令，该弹出命令用于指示弹出前置摄像头。
在一些实施例中，HAL层可以通过下层比如内核层控制前置摄像头弹出。比如，以图2所示的结构为例，HAL层可以通过内核层控制前置摄像头所在的升降件升起，带动前置摄像头升降。在一实施例中，手机100弹出前置摄像头之后，可以开启前置摄像头，前置摄像头采集图像。
1005：升降管理服务模块更新摄像头的状态记录表。
当HAL层通过内核层控制前置摄像头弹出之后，内核层可以向HAL层中的升降管理服务模块发送反馈指令，该反馈指令用于指示前置摄像头已经弹起，且前置摄像头已经开启。升降管理服务模块接收到反馈指令后，可以更新摄像头状态记录表，比如上表1，更新后的表可以如下表2：
摄像头 收回/升起 开启/关闭
前置摄像头 弹起 开启
后置摄像头 NA 关闭
表2
在一些实施例中，升降管理服务模块可以根据更新后的摄像头状态记录表，进行后续处理。
1006：第三方相机创建activity。
示例性的，第三方相机应用启动后，可以创建activity，可以通过内核层的显示驱动来驱动显示屏显示第三方相机应用的取景界面，比如图3中的(c)所示的取景界面307。该取景界面307中包括前置摄像头采集的图像。
1007：升降管理服务模块监听该activity的生命周期。
在一些实施例中，升降管理服务模块可以监听该activity的生命周期，即该activity的变化情况。
1008：第三方相机应用从前台切换到后台运行。
在一些示例中，以图6中的(a)为例，手机100的显示屏显示第三方相机应用的取景界面601。手机100中的微信收到新消息，在显示屏的状态栏显示微信收到的新消息。触摸传感器驱动检测到针对新消息的输入事件，将该输入事件通过上层上报给第三方相机应用。第三方相机应用后台运行，比如，第三方相机应用可以调用activity中暂停(onPause)功能，使得第三方相机应用后台运行。
1009：升降管理服务模块监听到该activity由焦点activity变化为非焦点activity。
在一些实施例中，焦点activity可以是可见的显示界面对应的activity，例如前台显示的 显示界面对应的activity；非焦点activity可以是不可见的显示界面对应的activity，例如，可以是后台运行的应用的显示界面对应的activity。通常，焦点activity可以接收用户输入操作，比如在触摸屏上的点击、滑动等操作，非焦点activity不可以接收用户输入操作。当一个activity由焦点activity变为非焦点activity时，即该activity对应的显示界面被切换到后台运行；当一个activity由非焦点activity变为焦点activity时，即该activity对应的显示界面前台到前台运行。
例如，电子设备启动第三方相机应用，第三方相机应用可以创建activity，前台显示该activity对应的显示界面即取景界面。也就是说，第三方相机应用创建的activity当前是焦点activity。若电子设备检测到返回主界面或者显示其他应用的显示界面的操作后，第三方应用创建的activity调用onPause，以启动另一个activity，则第三方相机应用创建的activity变为非焦点activity，所述另一个activity变为焦点activity，所述另一个activity例如可以是主界面对应的activity或者其它应用的显示界面对应的activity，即将第三方相机应用的显示界面从前台切换到后台，而前台显示主界面或其它应用的显示界面。再例如，电子设备在后台运行第三方相机应用，即第三方相机应用创建的activity当前是非焦点activity，前台显示主界面或者其他应用的显示界面，即主界面或其他应用的显示界面的activity是焦点activity。电子设备检测到用于将第三方相机应用切换到前台的操作，第三方相机应用创建的activity调用回调(onResume)功能，由非焦点activity变为焦点activity，在前台显示；而主界面或其他应用的显示界面对应的activity变为非焦点activity，在后台运行。
1010：升降管理服务模块从更新的摄像头的状态记录表中确定当前升起的摄像头。
如前文所述，升降管理服务模块升起前置摄像头后更新了摄像头的状态记录表。当升降管理服务模块监听到activity从前台切换到后台时，查询更新后的摄像头状态记录表比如上述表2，确定处于升起状态的是前置摄像头。升降管理服务模块可以向HAL层发送收回前置摄像头的命令。
1011：升降管理服务模块向HAL层发送收回前置摄像头的命令。
在一些实施例中，HAL层可以通过下层比如内核层控制前置摄像头收回。比如，以图2所示的结构为例，HAL层可以通过内核层控制前置摄像头所在的升降件收回，带动前置摄像头收回。在一实施例中，手机100收回前置摄像头之后，可以关闭前置摄像头。
示例性的，升降管理服务模块确定收回前置摄像头之后，可以更新摄像头记录状态表。比如更新上述表3，得到下表3。
摄像头 收回/升起 开启/关闭
前置摄像头 收回 开启
后置摄像头 NA 关闭
表3
1012：第三方相机应用从后台切换到前台运行。
在一些示例中，以图8中的(b)为例，手机100显示主界面802，后台运行第三方相机应用。触摸传感器驱动检测到输入事件(比如，点击主界面802中的第三方相机应用的输入事件)，将该输入事件通过上层上报给第三方相机应用。第三方相机应用从后台切换到前台运行，比如，第三方相机应用可以调用activity中回调(onResume)功能，使得第三方相机应用从后台切到前台运行。
1013：升降管理服务模块监听到该activity从非焦点activity变化为焦点activity。
在一些实施例中，第三方相机应用创建的activity后，若该activity调用onResume，则从非焦点activity改变为非焦点activity，所以第三方相机应用从后台切换到前台。
1014：升降管理服务模块根据摄像头的记录状态表，确定当前打开的摄像头是前置摄像头。
在一些实施例中，升降管理服务模块可以根据最新的摄像头状态记录表比如上表3，确定当前处于开启状态的摄像头，即前置摄像头，然后向HAL层发送升起前置摄像头的命令。
1015：升降管理服务模块向HAL层发送升起前置摄像头的命令。
因此，图8所示的实施例中，手机100将第三方相机应用从前台切换到后台时，可以收回前置摄像头，将第三方相机应用从后台切换到前台时，可以升起前置摄像头。
在一些实施例中，第三方相机应用启动前置摄像头后，若第三方相机应用始终在前台运行，该第三方相机应用对应的activity不会发生变化，也就是说，手机100显示第三方相机应用的取景界面时，若手机100检测到针对取景界面中的一个或多个控件的操作时，activity不会发生变化。升降管理服务模块检测到activity未变化时，可以保持前置摄像头处于升起状态。
举例来说，以图3中的(c)为例，手机100启动第三方相机应用，升起前置摄像头，显示取景界面307，取景界面307中包括分辨率切换控件309。触摸传感器驱动检测到输入事件，比如点击分辨率控件309的输入事件。触摸传感器驱动将该输入事件经过上层发送给第三方相机应用。第三方相机应用切换预览图像的分辨率。在该过程中，升降管理服务模块检测到activity未发生变化，所以可以不收回前置摄像头。
在其它实施例中，本申请实施例提供的摄像头升降控制方法，还可以适用于视频录制、视频通话等场景。视频录制场景，比如手机100通过系统相机或第三方相机应用录制视频；视频通话场景，比如手机100使用微信/QQ等即时通讯应用与其他设备进行视频通话场景。
参见图11所示，为手机100通过图9所示的软件架构实现视频通话时对摄像头的处理过程。以下实施例以微信应用为例。如图11所示，该过程可以包括：
1101，微信应用启动后，创建activity；例如，该activity可以对应微信应用中与某个联系人的聊天界面。
1102，升降管理服务模块监听该activity的生命周期。
1103，微信应用调用音频通话接口，启动音频模块。
在一些实施例中，微信应用可以通过HAL层中的音视频接口调用内核层中的音视频驱动，以驱动音频模块播放通话声音，例如，音频模块可以包括一个或多个扬声器。
1104，系统进入音频通话模式。
在一些实施例中，安卓系统可以包括多种声音模式(aduio mode)，例如，正常模式(mode_normal)，即没有铃声和电话的情况，响铃模式(mode_ringtone)、通话模式(mode_in_communication)等。其中，通话模式可以包括音频通话模式和视频通话模块。在一些实施例中，音视频接口可以包括模式设置(setmode)接口。微信应用可以调用该setmode接口设置声音模式(mode)，以实现不同的通话模式。例如，微信应用可以调用setmode接口设置mode的标志位为3，表征系统处于音频通话模式，再例如，微信应用可以调用setmode接口设置mode的标志位为2，表征系统处于视频通话模式。
1105，升降管理服务模块可以监听音频通话模式的变化情况。
在一些实施例中，升降系统或升降管理服务模块可以调用audio manager的扩展接口，注册声音模式(aduio mode)的监听事件，以监听系统的声音模式。比如，升降管理服务模块监听到声音模式的标志位被设置为3，则确定系统当前处于音频通话模式。
1106，微信应用向升降系统发送打开前置摄像头的指令。
1107，升降系统向升降管理服务模块发送打开前置摄像头的指令。
1108，升降管理服务模块向HAL层发送升起/弹出前置摄像头的指令。
1109，微信应用接通视频通话。
在一些实施例中，手机100检测到对方设备接听视频通话时，可以进入视频通话模式。在视频通话模式下，手机100可以将前置摄像头采集的图像实时的、不断地发送给对方设备。
1110，系统进入视频通话模式。
在一些实施例中，微信应用接通视频接通之后可以通过setmode接口设置mode标志位为2，表征当前处于视频通话模式。
1111，升降管理服务模块监听到系统由音频通话模式进入视频通话模式。
在一些实施例中，升降管理服务模块可以监听声音模式(mode)，例如可以实时的查看声音模式的标志位，假设监听到该标志位被设置为2时，确定系统当前处于视频通话模式。
1112，升降管理服务模块记录处于视频通话模式的应用是微信应用，记录使用前置摄像头的activity是微信应用的activity。
在一些实施例中，升降管理服务模块可以记录处于视频通话模式的应用，即微信应用，还可以记录当前使用前置摄像头的activity是微信应用的activity，例如记录该activity的名称。
1113，微信应用从前台切换到后台运行。
1114，升降管理服务模块监听到微信应用的activity由焦点activity变为非焦点activity。
在该实施例中，升降服务管理模块监听到微信应用的activity从焦点activity变为非焦点activity，即微信应用从前台切换到后台运行时，可以进一步判断是否要保持前置摄像头处于升起状态。
1115，升降管理服务模块判断当前是否处于视频通话模式，若是，则执行1116，若否，则执行1118。
在一些实施例中，升降管理服务模块可以判断当前的mode的标志位是否为3，若是，确定系统处于视频通话模式；若否，说明系统当前不处于视频通话模式，无需使用摄像头，可以收回摄像头。
1116，升降管理服务模块判断当前处于视频通话模式的应用是否是微信应用，若是，则执行1117，若否，则执行1118。
如前文所述，升降管理服务模块记录处于视频通话模式的应用，所以，升降管理服务模块判断当前处于视频通话模式的仍然是微信应用时，可以继续执行1117，若不是微信应用，可以收回摄像头。
1117，升降管理服务模块判断当前使用前置摄像头的activity是微信应用的activity；若是，则执行1119，若否，则执行1118。
如前文所述，升降管理服务模块还可以记录当前使用前置摄像头的activity，例如 activity的名称。因此，升降管理服务模块可以判断使用前置摄像头的activity是否是微信应用的activity，若是，则升降管理服务模块可以不向HAL层发送收回前置摄像头的指令；若否，则向HAL层发送收回摄像头的指令。
1118，升降管理服务模块向HAL层发送收回摄像头的指令。
1119，升降管理服务模块不向HA层发送收回摄像头的指令。
在图11所示的实施例中，手机100中的微信应用进入视频通话模式后，若微信应用从前台切换到后台，手机100可以继续保持摄像头处于升起状态。在另一些实施例中，手机100中的微信应用进入视频通话模式后，若微信应用从前台切换到后台，但前台显示微信的悬浮窗口，该悬浮窗口中显示视频通话界面时，手机100可以继续保持摄像头处于升起状态。
