Description

一种屏幕唤醒方法、装置及终端设备 技术领域
本发明实施例涉及触控技术领域，尤其涉及一种屏幕唤醒方法、装置及终端设备。
背景技术
指纹识别技术是一种通过指纹传感器采集到人体的指纹图像，然后与系统里的已有指纹信息进行比对，通过判断正确与否以实现身份识别的技术。
依据人体指纹的唯一性和使用便捷性，指纹识别技术已经大量应用于多个领域的设备上。指纹识别解锁技术是指纹识别技术的重要组成部分，其中，暗屏解锁是其中最为常见的技术之一。
对于终端设备来说，可能有两种情况会使终端设备暗屏，一种为终端设备处于待机状态，一种为终端设备处于深度休眠状态。其中，当终端设备开机但不进行任何实质性工作时，可以认为终端设备会处于待机状态；待机状态持续一段时间后，终端设备将进入更加低功耗省电模式，此时，可以认为终端设备处于深度休眠状态。在这两种状态下，终端设备都会暗屏。
当用户对暗屏的终端设备的指纹传感器进行触摸操作时，会触发终端设备的亮屏及后续的指纹解锁过程。目前，对于处于深度休眠状态的终端设备，当终端设备接收到触摸操作时，需要等待操作系统唤醒处理器后，才能进行后续操作。
然而，对于处于深度休眠状态的终端设备，触摸操作引发唤醒处理器的过程需要相当长的时间，相应地，当终端设备处于深度休眠状态时的解锁时间也更长。因此，如何在终端设备处于深度休眠状态下，尽可能缩短处理器的唤醒时间，提高对触摸操作的处理效率成为亟待解决的一个问题。
发明内容
本发明实施例提供一种屏幕唤醒方法、装置及终端设备，以解决现有终端设备处于深度休眠状态时，如何缩短处理器唤醒时间的问题。
根据本发明实施例的第一方面，提供了一种屏幕唤醒方法，包括：在获取到指纹传感器被触摸所触发的中断指令时，判断终端设备当前是否处于深度休眠状态；若处于深度休眠状态，则向所述终端设备的处理器发送唤醒指令，唤醒所述处理器。
根据本发明实施例的第二方面，还提供了一种屏幕唤醒装置，包括：判断模块，用于在获取到指纹传感器被触摸所触发的中断指令时，判断终端设备当前是否处于深度休眠状态；唤醒模块，用于若处于深度休眠状态，则向所述终端设备的处理器发送唤醒指令，唤醒所述处理器。
根据本发明实施例的第三方面，还提供了一种终端设备，包括：指纹传感器和控制单元，所述指纹传感器与所述控制单元电连接；所述指纹传感器，用于接收触摸操作，并采集所述触摸操作的指纹信息；所述控制单元，用于依据所述指纹传感器接收的所述触摸操作和采集的所述指纹信息，执行如第一方面中所述的屏幕唤醒方法所对应的操作。
根据本发明实施例提供的屏幕唤醒方案，在获取到指纹传感器被触摸所触发的中断指令时，判断终端设备当前是否处于深度休眠状态，若处于深度休眠状态，则向终端设备的处理器发送唤醒指令，唤醒处理器，进而唤醒终端设备的显示屏幕。与现有技术相比，本发明实施例提供的方案中，一旦收到中断指令且判断终端设备处于深度休眠状态时，即向处理器主动发起唤醒指令，唤醒指令无需到达操作系统HAL层，不再需要等待操作系统HAL层对处理器的唤醒处理，节省了处理器唤醒的等待时间，提高了对触摸操作的处理效率，也提高了处理器唤醒效率。

具体实施方式
为使得本发明实施例的发明目的、特征、优点能够更加的明显和易懂，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明实施例一部分实施例，而非全部实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明实施例保护的范围。
请参阅图1，其为一种典型的屏幕唤醒方法的流程图。从图1中可见当用户触摸指纹传感器后，指纹传感器依据用户的触摸操作触发中断，生成中断指令，将该中断指令上报至操作系统HAL层；操作系统HAL层接收到该中断指令时，判断当前终端设备的状态，当确定当前终端设备处于深度休眠状态时，由操作系统HAL层唤醒终端设备的处理。然而，对于处于深度休眠状态的终端设备，触摸操作引发的指令到达操作系统HAL层，以及操作系统HAL层对该指令进行处理后再唤醒处理器的过程均需要相当长的时间，相应地，当终端设备处于深度休眠状态时的解锁时间也更长。
本发明实施例提供一种屏幕唤醒方法、装置及终端设备，以缩短终端设备处于深度休眠状态的唤醒时间。

参照图2，示出了本发明实施例一的一种屏幕唤醒方法的步骤流程图。
本实施例的屏幕唤醒方法包括以下步骤：
步骤101：在获取到指纹传感器被触摸所触发的中断指令时，判断终端设备当前是否处于深度休眠状态。
用户对指纹传感器的操作通常会触发中断指令，例如，对指纹传感器进行手指按下操作或者手指抬起操作等。本发明实施例中，指纹传感器被触摸所触发的中断指令主要是用户进行手指按下操作时触发的中断指令。当获取到该中断指令时，会进一步判断终端设备当前是否处于深度休眠状态。
本发明实施例中，指纹传感器是实现指纹采集的关键器件。其中，指纹传感器包括但不限于光学指纹传感器、半导体指纹传感器、热敏式指纹传感 器、超声波指纹传感器、压感式指纹传感器等。
此外，本发明实施例中的终端设备可以是任意适当的终端设备，包括但不限于：手机、平板电脑、台式电脑等。
步骤102：若处于深度休眠状态，则向终端设备的处理器发送唤醒指令，唤醒处理器。
一种典型的处理器唤醒方式中，当用户触摸指纹传感器后，指纹传感器依据用户的触摸操作触发中断，生成中断指令，将该中断指令上报至操作系统HAL层；操作系统HAL层接收到该中断指令时，判断当前终端设备的状态，当确定当前终端设备处于深度休眠状态时，由操作系统HAL层唤醒终端设备的处理器。而对于本发明实施例，当用户触摸指纹传感器后，指纹传感器依据用户的触摸操作触发中断，在生成中断指令的同时判断终端设备是否处于深度休眠状态；当判断结果为终端设备处于深度休眠状态时，即向终端设备的处理器发起唤醒指令，依据唤醒指令唤醒终端设备的处理器；当中断指令上报到操作系统HAL层时，终端设备的处理器已经处于唤醒状态。
可见，相比现有技术中对处理器的唤醒过程，唤醒指令无需到达操作系统HAL层，不再需要等待操作系统HAL层对处理器的唤醒处理，节省了处理器唤醒的等待时间。
根据本发明实施例提供的屏幕唤醒方法，在获取到指纹传感器被触摸所触发的中断指令时，判断终端设备当前是否处于深度休眠状态，若处于深度休眠状态，则向终端设备的处理器发送唤醒指令，唤醒处理器，进而唤醒终端设备的显示屏幕。与现有技术相比，本发明实施例提供的方案中，一旦收到中断指令且判断终端设备处于深度休眠状态时，即向处理器主动发起唤醒指令，唤醒指令无需到达操作系统HAL层，不再需要等待操作系统HAL层对处理器的唤醒处理，节省了处理器唤醒的等待时间，提高了对触摸操作的处理效率，也提高了处理器唤醒效率。
本实施例的屏幕唤醒方法可以由任意适当的具有数据处理功能的装置或设备实现，如终端设备等。
实施例二
参照图3，示出了本发明实施例二的一种屏幕唤醒方法的步骤流程图。
本实施例的屏幕唤醒方法包括以下步骤：
步骤201：在获取到指纹传感器被触摸所触发的中断指令时，判断终端设备当前是否处于深度休眠状态。
如前所述，本发明实施例中，指纹传感器被触摸所触发的中断指令主要是用户进行手指按下操作时触发的中断指令。当获取到该中断指令时，进一步判断终端设备当前是否处于深度休眠状态。
在一种可行方式中，在获取到指纹传感器被触摸所触发的中断指令时，通过终端设备的驱动层判断终端设备当前是否处于深度休眠状态。
一般来说，处于深度休眠状态的终端设备在进行处理器唤醒时，以Android系统为例，唤醒指令从Android系统的最上层(如Java的应用程序)，经过Java、C++和C语言写的Framework层、JNI(Java Native Interface)层、HAL层最后到达Android系统的最底层(Kernel层)。经过这一系列的操作，最终由HAL层判断终端设备当前是否处于深度休眠状态，进而进行后续的唤醒处理。与上述方式不同，本发明实施例中，在获取到指纹传感器被触摸所触发的中断指令时，即向驱动层发送，由驱动层判断终端设备当前是否处于深度休眠状态，进而进行后续的唤醒处理。可见，不论是进行终端设备当前状态判断的具体执行主体，还是进行唤醒处理的时机，本发明实施例的方案均与上述方式不同，也由此提高了唤醒处理的效率，缩短了唤醒处理的等待时间。
步骤202：若终端设备处于深度休眠状态，判断用于指示是否唤醒处理器的唤醒开关是否处于打开状态。
其中，唤醒开关是用来控制是否唤醒处理器的指示开关，用于指示是否唤醒处理器。若唤醒开关处于打开状态，则表示当前终端设备的处理器处于深度休眠状态，需要唤醒处理器，因此，打开状态可以指示对处理器进行唤醒操作；若唤醒开关处于关闭状态，则表示当前终端设备的处理器处于唤醒状态，不需要对处理器进行唤醒，因此，关闭状态可以指示不对处理器进行唤醒操作。对唤醒开关的设置如下文所述，在此不再详述。
步骤203：若唤醒开关处于打开状态，则向终端设备的处理器发送唤醒指令。
在一种可行方式中，若唤醒开关处于打开状态，可以通过终端设备的HAL 层向终端设备的处理器发送唤醒指令。HAL层是位于终端设备的操作系统内核与硬件设备之间的接口层，其可以将硬件设备抽象化后供开发人员使用，屏蔽了硬件设备的复杂实现。通过HAL层向处理器发送唤醒指令，简化了唤醒操作的复杂实现，减轻了开发人员的负担。
一种通过本实施例的方案唤醒处理器的过程示意如图4所示，从图4中可见，当用户触摸指纹传感器后，指纹传感器依据用户的触摸操作触发中断，在生成中断指令的同时判断终端设备是否处于深度休眠状态；当确定终端设备处于深度休眠状态时，即向终端设备的处理器发起唤醒指令，依据唤醒指令唤醒终端设备的处理器；当中断指令上报到操作系统HAL层时，终端设备的处理器已经处于唤醒状态。
通过上述过程，实现了终端设备的处理器的唤醒。进一步地，基于唤醒后的处理器，本领域技术人员还可以进行以下可选操作的设置。
步骤204：对指纹传感器被触摸时采集的指纹信息进行识别，并根据识别结果对终端设备解锁。
当处理器处于唤醒状态后，依据指纹传感器采集的指纹信息进行指纹识别。例如，处理器可以将指纹传感器采集的指纹数据与终端设备内存储的指纹数据进行比对，当比对结果一致时，对终端设备进行解锁；而当比对结果不一致时，则可以由本领域技术人员根据实际情况适当设置，如，提示出错、终端设备的处理器再次进入深度休眠状态等。
步骤205：确定中断指令对应的触摸操作的类型。
需要说明的是，本步骤与步骤204的执行不分先后顺序，也可以并行执行，还可以择一执行。
在一种可行方式中，可以通过终端设备的HAL层接收终端设备的驱动层发送的中断指令，并通过HAL层根据中断指令确定触摸操作的类型。HAL层依据接收的中断指令对触摸操作的类型进行确定。其中，触摸操作的类型包括：抬起操作和按下操作。
步骤206：依据触摸操作的类型设置唤醒开关的状态。
包括：若触摸操作的类型为按下操作时，将唤醒开关的状态设置为关闭状态；若触摸操作的类型为抬起操作时，将唤醒开关的状态设置为打开状态。
在一种可行方式中，可以通过终端设备的HAL层向驱动层发送与触摸操 作的类型对应的设置指令；通过终端设备的驱动层将唤醒开关设置为所述设置指令所指示的状态。
例如：当触摸操作的类型为抬起时，设置指令为1，指示将唤醒开关设置为打开状态；当触摸操作的类型为按下时，设置指令为0，指示将唤醒开关设置为关闭状态。
本实施例中，唤醒开关的状态可以由操作系统的HAL层以及驱动层配合进行设置和调整，HAL层是位于操作系统内核与硬件设备之间的接口层，其可以将硬件设备抽象化后供开发人员使用，屏蔽了硬件设备的复杂实现；驱动层可以提供控制硬件设备的途径。通过HAL层和驱动层，可以简单有效地实现唤醒开关的设置。
通过本实施例的上述屏幕唤醒方案，当对处于深度休眠状态的终端设备中进行解锁时，通过检测，可以节省50-100ms的时间。
根据本实施例提供的屏幕唤醒方法，在获取到指纹传感器被触摸所触发的中断指令时，判断终端设备当前是否处于深度休眠状态，若处于深度休眠状态，则向终端设备的处理器发送唤醒指令，唤醒处理器，进而唤醒终端设备的显示屏幕。与现有技术相比，本实施例提供的方案中，一旦收到中断指令且判断终端设备处于深度休眠状态时，即向处理器主动发起唤醒指令，唤醒指令无需到达操作系统HAL层，不再需要等待操作系统HAL层对处理器的唤醒处理，节省了处理器唤醒的等待时间，提高了对触摸操作的处理效率，也提高了处理器唤醒效率。
本实施例的屏幕唤醒方法可以由任意适当的具有数据处理功能的装置或设备实现，如终端设备等。
