图1为本发明实施例中提供的一种屏幕背光调节方法的流程示意图,该方法可以由屏幕背光调节装置执行,该装置可由软件或硬件实现,一般可集成或加载在电子设备中。如图1所示,该方法可以包括:
步骤11、若背光控制功能处于开启状态,则确定当前应用程序是否为图像处理类应用程序。
其中,图像处理类应用程用于编辑和/或展示图像。如图像处理类应用程序可以是终端中预先确定的画面质量要求高的应用程序,诸如相册应用、光影魔术和美图秀秀之类的应用程序可以是图像处理类应用程序。
其中,终端可以依据用户需求个性化地确定图像处理类应用程序。例如,终端中应用程序可以具有标识符,该标识符用于表征应用程序的类型,如具有特定标识符的应用程序属于图像处理类应用。相应的,用户在安装或使用某一应用程序的过程中,若对该应用程序的画面质量要求较高,可以为该应用程序添加特定标识符,从而将该应用程序确定为图像处理类应用程序。
步骤12、若所述当前应用程序为图像处理类应用程序,则控制背光控制功能处于关闭状态。
在一实施方式中,若当前应用程序属于画面质量要求高的图像处理类应用程序,则直接控制背光控制功能处于关闭状态,避免了通过背光控制功能对图像处理类应用程序的图像灰阶以及屏幕背光亮度进行调整,可以满足用户对画面质量的要求,相比于通过人工方式关闭背光控制功能,简化了操作,降低了终端的功耗。
步骤13、将屏幕背光亮度减去亮度基准值。
其中,亮度基准值的数量可以是一个,也可以是多个,即在关闭背光控制功能后可以不止一次降低屏幕背光亮度,从而避免背光闪烁。并且,亮度基准值可以是与屏幕亮度无关的固定数值,也可以依据屏幕亮度确定。
其中,在有一个亮度基准值的情况下,将背光控制功能关闭后的第一屏幕背光亮度减去背光控制功能关闭前的第二屏幕背光亮度,得到所述亮度基准值。该方案可以降低背光控制功能关闭后,屏幕背光亮度恢复导致的背光闪烁。
进一步的,在有多个亮度基准值的情况下,可以将背光控制功能关闭后的第一屏幕背光亮度减去背光控制功能关闭前的第二屏幕背光亮度,得到第一亮度基准值,并将屏幕背光亮度减去第一亮度基准值;随后,将第一屏幕背光亮度减去预设数值得到第二屏幕背光亮度,并将屏幕背光亮度减去第二亮度基准值,以此类推,直到检测出不存在背光闪烁现象。另外,可以依据屏幕相邻显示帧的变化信息来确定是否存在背光闪烁现象。
本发明实施例在背光控制功能处于开启状态过程中,确定当前应用程序是否为图像处理类应用程序,若是,则控制背光功能处于关闭状态,并将屏幕背光亮度减去亮度基准值。可以保证图像处理类应用程序的画面质量,以及降低终端功耗,防止背光闪烁。

若所述当前应用程序不为图像处理类应用程序,则检测屏幕背光亮度;
若检测到的屏幕背光亮度低于预设的背光亮度阈值,则控制背光控制功能处于关闭状态。
在一实施方式中,若屏幕背光亮度低于背光亮度阈值,则屏幕背光亮度的下降空间较小,可以直接控制背光控制功能处于关闭状态。

需要说明的是,若所述当前应用程序不为图像处理类应用程序,在控制背光控制功能处于关闭状态后,也可以将屏幕背光亮度减去亮度基准值,从而避免背光控制功能切换导致的背光闪烁。
在上述实施例的基础上,参考图2,为了进一步提高屏幕背光调节效果,屏幕背光调节方法可以包括:
步骤21、若背光控制功能处于开启状态,则获取所述当前应用程序的标识信息。
