具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处描述的实施例仅仅用以解释本申请，并不用于限定本申请。
本申请提供的移动终端帧率的控制方法，可以应用于如图1所示的应用场景中。该应用场景包括移动终端102和服务器104，移动终端102通过网络与服务器104连接。移动终端102发起画面切换请求，服务器104接收画面切换请求，画面切换请求用于请求切换应用程序中的画面；根据画面切换请求，调用应用程序对应的控件，控件用于绘制应用程序对应的待切换画面；当检测到应用程序调用预设的特征控件时，得到应用程序对应的场景以及场景对应的显示帧率；根据画面切换请求以及显示帧率，显示应用程序对应的待切换画面。移动终端102可以是手机、平板电脑、笔记本电脑等中的至少一种。服务器104可以用独立的服务器或者是多个服务器组成的服务器集群来实现。
需要指出的是，本申请实施例中的移动终端帧率的控制方法还可以由终端来执行，终端接收外部输入的画面切换请求，画面切换请求用于请求切换应用程序中的画面；根据画面切换请求，调用应用程序对应的控件，控件用于绘制应用程序对应的待切换画面；当检测到应用程序调用预设的特征控件时，得到应用程序对应的场景以及场景对应的显示帧率；根据画面切换请求以及显示帧率，显示应用程序对应的待切换画面。具体地，终端执行本申请实施例中的移动终端帧率的控制方法可以通过处理器来执行，终端可以接收来自外部其他终端的输入的画面切换请求，以执行上述操作，完成切换画面的显示。
在一个实施例中，如图2所示，提供了一种移动终端帧率的控制方法，以该方法应用于图1中的服务器为例进行说明，包括以下步骤。
步骤202，接收画面切换请求，画面切换请求用于请求切换应用程序中的画面。
其中，画面切换请求是指用于请求切换移动终端的应用程序中的画面， 可以是由用户在移动终端的交互页面触发相应的控件发起画面切换请求，移动终端的处理器接收该画面切换请求；也可以是用户在移动终端的交互页面触发相应的控件发起画面切换请求，移动终端在检测到将该画面切换请求时，将其发送至服务器。画面切换请求可以是基于一个应用程序，请求从一个场景画面切换至另一个场景画面，比如从用户登录页面切换至视频观看页面；也可以是基于不同的应用程序，请求从一个应用程序页面切换至另一个应用程序页面，比如从某一个视频应用程序切换至某一个游戏应用程序。
步骤204，根据画面切换请求，调用应用程序对应的控件，控件用于绘制应用程序对应的待切换画面。
其中，应用程序在显示不同的场景画面时需要调用不同的控件来实现，比如，游戏应用程序在显示场景画面时，需要调用SurfaceView控件、TextureView控件、NativeActivity控件等控件。
步骤206，当检测到应用程序调用预设的特征控件时，得到应用程序对应的场景以及场景对应的显示帧率。
其中，特征控件是指应用程序在某个场景下需要使用而其它场景下不需要使用的控件，可以通过特征控件的调用来识别不同的场景。显示帧率是指移动终端的显示屏幕更换一帧画面的时间间隔，预先存储场景与显示帧率的对应关系表，比如，游戏场景对应60Hz的显示帧率、视频场景对应60Hz的显示帧率、网页浏览场景对应90Hz的显示帧率等。移动终端的屏幕硬件支持多种显示帧率，比如支持60Hz和90Hz的显示帧率，屏幕工作在90Hz时能够给用户带来更流畅的体验，而工作在60Hz时能够节省屏幕功耗。具体地，游戏场景和视频场景由于画面内容限制，电影录制一般而言是每秒24帧，因此这两种场景下的显示帧率不会超过60Hz，如果此时屏幕以90Hz或更高的显示帧率工作并不能提高流畅性，而屏幕工作在60Hz却可以节省功耗；对于滑动应用列表或者浏览微博等场景，不受画面内容限制，此时屏幕工作在90Hz，能给用户带来更流畅的体验。
步骤208，根据画面切换请求以及显示帧率，显示应用程序对应的待切 换画面。
在画面切换请求包括多个请求的情况下，可以基于画面切换请求中携带的特征信息，比如时间属性信息，对画面切换请求按时间先后排序，依次处理画面切换请求。
上述移动终端帧率的控制方法，通过接收画面切换请求，画面切换请求用于请求切换应用程序中的画面；根据画面切换请求，调用应用程序对应的控件，以生成应用程序对应的待切换画面；当检测到应用程序调用预设的特征控件时，得到应用程序对应的场景以及场景对应的显示帧率；根据画面切换请求以及显示帧率，显示应用程序对应的待切换画面，这样实现了显示帧率与移动终端的场景对应，即不同场景下对应不同的显示帧率，而不是所有的场景下都对应同一个较高的显示帧率，因而可以降低移动终端的功耗。
在一个实施例中，如图3所示，当检测到应用程序调用预设的特征控件时，得到应用程序对应的场景以及场景对应的显示帧率包括：步骤302，当检测到应用程序调用预设的特征控件时，获取特征控件的显示尺寸、特征控件的属性以及预设的白名单；步骤304，根据特征控件的显示尺寸、特征控件的属性以及白名单，得到应用程序对应的场景以及场景对应的显示帧率。具体地，场景包括第一类场景和第二类场景，第一类场景和第二类场景对应的显示帧率不同；根据特征控件的显示尺寸、特征控件的属性以及白名单，得到应用程序对应的场景以及场景对应的显示帧率包括：根据白名单查询应用程序对应的显示帧率属于第一类场景对应的显示帧率或属于第二类场景对应的显示帧率，得到查询结果；根据特征控件的显示尺寸、特征控件的属性以及查询结果，确定应用程序对应场景以及场景对应的显示帧率。更为具体地，当特征控件的显示尺寸为预设尺寸值、特征控件的属性包括预设的标签属性，且根据白名单查询得到应用程序对应的显示帧率为预设第一类场景对应的显示帧率，得到应用程序对应的场景为第一类场景以及第一类场景对应的显示帧率；当特征控件的显示尺寸小于预设尺寸值、特征控件的属性不包括预设的标签属性，且根据白名单查询得到应用程序对应的显示帧率为预设 第二类场景对应的显示帧率，得到应用程序对应的场景为第二类场景以及第二类场景对应的显示帧率。其中，预设尺寸值可以是移动终端的屏幕尺寸值，第一类场景是指画面内容受限于录制帧率的场景，比如游戏场景或视频场景等，第一类场景对应的显示帧率可以是60Hz，第二类场景是指画面内容不受限的场景，比如网页浏览场景，第二类场景对应的显示帧率可以是90Hz。
特征控件的显示尺寸是指调用特征控件在屏幕上进行显示时，对应的画面尺寸。比如在视频场景下，应用程序调用的某个特征控件对应的显示尺寸应该是全屏，如果实际情况下获取到该应用程序中声明的该特征控件的显示尺寸小于屏幕尺寸的一半，此时判定该实际情况对应的并不是视频场景，也即该场景不属于需要将显示帧率设置为60Hz的场景。特征控件的属性是指在不同场景下调用特征控件，特征控件所携带的特定标签。不同的特征控件对应不同的属性，同一个特征控件在不同场景下某些属性也会不同，可以通过这些特定的属性来识别不同的场景。比如SurfaceView控件的sublayer属性，这个属性在游戏和视频应用程序调用时一般会携带media标签，而其它应用程序调用该控件时则不会携带该标签。可以预先配置一个白名单，该白名单的内容包括工作在60Hz的应用程序清单以及工作在90Hz的应用程序清单。非必要的，该白名单可以支持用户在线配置，根据需要进行修改。通过特征控件的调用对场景进行识别，可能会出现场景识别不准确的问题，比如有些小说类应用程序、谷歌浏览器在运行时调用SurfaceView控件，但是这些应用程序并不属于游戏视频类应用程序，且工作在90Hz时，用户体验会更流畅。在应用程序调用预设的特征控件基础上，再通过特征控件的显示尺寸、特征控件的属性以及白名单进行场景确认，可以提高场景识别率。
在一个实施例中，根据画面切换请求以及显示帧率，显示应用程序对应的待切换画面包括：根据画面切换请求确定目标应用程序，将目标应用程序对应的显示帧率设置为场景对应的显示帧率；在接收到目标应用程序对应的画面绘制完成消息时，根据设置的显示帧率显示目标应用程序对应的待切换画面。以操作系统为android系统的手机作为移动终端为例，屏幕工作模式客 户端ScreenModeClient和应用程序运行在同一进程，当某个应用程序调用特征控件时，得到该应用程序对应的场景以及该场景对应的显示帧率，将该应用程序以及该应用程序在该场景下对应的显示帧率发送至屏幕工作模式服务ScreenModeService。ScreenModeService在系统服务中，为每个应用程序建立一条记录，记录该应用程序在该场景下对应的显示帧率。android原生服务WindowManagerService先判断将某个应用程序显示于前台，然后从屏幕工作模式服务ScreenModeService获取该应用程序在该场景下对应的显示帧率，并且将待显示的应用程序对应的显示帧率设置为场景对应的显示帧率。从用户点击屏幕切换应用程序，到应用程序完成切换显示于屏幕，这中间存在延迟，不可避免地造成显示帧率切换不够迅速，比如从60Hz切换至90Hz不够快可能会造成待切换画面以60Hz运行，造成画面卡的问题。对此进行优化，无需等待目标应用程序画面绘制完毕后，才设置该应用程序对应的显示帧率，而在用户点击屏幕，系统判断某个应用程序将要调至前台显示时，先查询基于该应用程序画面切换请求得到的场景对应的显示帧率，提前将待显示的应用程序对应的显示帧率设置为场景对应的显示帧率。这之后这个应用程序确实显示于屏幕，由此提高了切换速度。
在一个实施例中，根据设置的显示帧率显示目标应用程序对应的待切换画面之后，还包括：当接收到待切换画面未显示的反馈消息时，延时预设时长，对目标应用程序对应的显示帧率进行切换，以使移动终端根据切换后的显示帧率显示待切换画面。在用户点击屏幕，系统判断某个应用程序将要调至前台显示时，先查询基于该应用程序画面切换请求得到的场景对应的显示帧率，提前将待显示的应用程序对应的显示帧率设置为场景对应的显示帧率，并保持预设时长，比如保持1秒。在1秒后，如果待切换画面没有在终端显示，对待显示的应用程序对应的显示帧率进行切换，以使移动终端根据切换后的显示帧率显示待切换画面。比如，提前设置的显示帧率为60Hz时，画面没有在终端显示，1秒后自动将显示帧率切换至90Hz，以显示画面。
在一个实施例中，移动终端用户交互界面设置有场景切换帧率控件，如 图4所示，根据画面切换请求以及显示帧率，显示应用程序对应的待切换画面之前，还包括：步骤404，获取应用程序基于系统帧率切换原生机制得到的显示帧率；步骤405，响应对场景切换帧率控件的激活操作，根据基于系统帧率切换原生机制得到的显示帧率以及场景对应的显示帧率，确定目标显示帧率；根据画面切换请求以及显示帧率，显示应用程序对应的待切换画面包括：步骤406，根据画面切换请求以及目标显示帧率，显示应用程序对应的待切换画面。可选地，根据基于系统帧率切换原生机制得到的显示帧率以及场景对应的显示帧率，确定目标显示帧率包括：获取预设的帧率影响因素优先级；根据帧率影响因素优先级、基于系统帧率切换原生机制得到的显示帧率以及场景对应的显示帧率，确定目标显示帧率。本实施例中的方案可以兼容移动终端的原生机制，比如安卓原生系统提供了接口，通过该接口可以设置应用程序的显示帧率。ScreenModeService综合考虑安卓原生接口、用户的设置、白名单、特征控件等影响因素，根据各个影响因素的优先级，得出合适的显示帧率。
应该理解的是，虽然图2-4的流程图中的各个步骤按照箭头的指示依次显示，但是这些步骤并不是必然按照箭头指示的顺序依次执行。除非本文中有明确的说明，这些步骤的执行并没有严格的顺序限制，这些步骤可以以其它的顺序执行。而且，图2-4中的至少一部分步骤可以包括多个子步骤或者多个阶段，这些子步骤或者阶段并不必然是在同一时刻执行完成，而是可以在不同的时刻执行，这些子步骤或者阶段的执行顺序也不必然是依次进行，而是可以与其它步骤或者其它步骤的子步骤或者阶段的至少一部分轮流或者交替地执行。
在一个实施例中，如图5所示，提供了一种移动终端帧率的控制装置，移动终端帧率的控制装置包括：请求接收模块502、请求响应模块504、特征控件检测模块506和画面显示模块508。其中，请求接收模块502，用于接收画面切换请求，画面切换请求用于请求切换应用程序中的画面。请求响应模块504，用于根据画面切换请求，调用应用程序对应的控件，控件用于绘制 应用程序对应的待切换画面。特征控件检测模块506，用于当检测到应用程序调用预设的特征控件时，得到应用程序对应的场景以及场景对应的显示帧率。画面显示模块508，用于根据画面切换请求以及显示帧率，显示应用程序对应的待切换画面。
在一个实施例中，特征控件检测模块506还用于当检测到应用程序调用预设的特征控件时，获取特征控件的显示尺寸、特征控件的属性以及预设的白名单；根据特征控件的显示尺寸、特征控件的属性以及白名单，得到应用程序对应的场景以及场景对应的显示帧率。
在一个实施例中，场景包括第一类场景和第二类场景，第一类场景和第二类场景对应的显示帧率不同；特征控件检测模块还用于根据白名单查询应用程序对应的显示帧率属于第一类场景对应的显示帧率或属于第二类场景对应的显示帧率，得到查询结果；根据特征控件的显示尺寸、特征控件的属性以及查询结果，确定应用程序对应场景以及场景对应的显示帧率。

在一个实施例中，帧率确定模块还用于获取预设的帧率影响因素优先级； 根据帧率影响因素优先级、基于系统帧率切换原生机制得到的显示帧率以及场景对应的显示帧率，确定目标显示帧率。
