在一个实施例中，如图2所示，提供了一种屏幕保护方法，以该方法应用于图1中的终端为例进行说明，包括以下步骤：
步骤202，确定当前显示界面上显示图像中的目标视图元素。
其中，视图(View)是指显示界面上满足用户交互需求的一系列元素；视图存在对应的视图元素标识，视图元素标识用于标记不同的视图。其中，目标视图元素是需要进行亮度检测的视图，显示界面是指应用程序的界面，应用程序至少包括一个显示界面。视图可以是一个元素集合(ViewGroup)，可以包括多个视图元素；视图是以树状结构组织起来的，在视图树状结构中，树的根节点对应的界面根节点(ViewRoot)，根节点中的每个子节点与视图中每个视图元素存在一一对应的关系。视图可以但不仅限于是窗口、文本框、按钮、滚动条等。
具体地，当终端中的应用启动时，在终端OLED显示屏显示应用对应的显示界面，显示界面上显示图像包括至少一个视图；获取应用的应用标识，从终端的本地数据库中查询与该应用标识对应的历史烧屏数据，并保存查询时间；本地数据库中包括分层配置信息库，历史烧屏数据可以是分层配置信息集合，分层配置信息集合中包括导致烧屏应用的应用标识、界面标识、视图元素标识等；根据分层配置信息集合中与应用标识对应的视图元素标识确定当前显示界面上显示图像中的目标视图元素。
