图5是本发明实施例提供的待机状态控制移动终端的结构示意图。
为使本发明的目的、技术方案和优点更加清楚明白，以下结合具体实施例，并参照附图，对本发明进一步详细说明。
需要说明的是，本发明实施例中所有使用“第一”和“第二”的表述均是为了区分两个相同名称非相同的实体或者非相同的参量，可见“第一”“第二”仅为了表述的方便，不应理解为对本发明实施例的限定，后续实施例对此不再一一说明。
本发明的第一个方面，提供了一种在不借助于用户的手动操作的情况下，也能实现待机状态的控制的待机状态控制方法。如图1所示，图1为本发明提供的待机状态控制方法的一个实施例的流程示意图。
所述待机状态控制方法，应用于移动终端，所述移动终端具有加速度传感器和前置摄像头；所述加速度传感器是，可以检测到移动终端发生移动并将该移动产生的物理数据(如速度、加速度、位移等)转换成加速度数据或传递到移动终端的处理器后可以通过计算得到加速度数据的传感器或与传感器类似的设备，例如陀螺仪、重力传感器、振动传感器、加速度计等等；
所述方法包括以下步骤：
步骤101：在处于待机状态时，持续采集所述加速度传感器产生的加速度数据；亦即，在移动终端处于待机状态时，开启对加速度传感器的监测；
步骤102：根据所述加速度数据，判断是否发生预开机动作；
其中，所述预开机动作是指所述移动终端在用户的操作下发生了预设的动
作，而这种动作通常情况下表明用户需要使用移动终端，例如被用户拿起；所述预开机动作的判断方法可以是，在移动终端中预先设置，当加速度数据出现某种变化或呈现某种变化趋势时，认定为发生预开机动作；
步骤103：若发生所述预开机动作，则开启所述前置摄像头，利用该前置摄像头采集图像；
步骤104：根据所述前置摄像头采集的图像，判断用户是否正在注视屏幕；
其中，用户是否正在注视屏幕的判断方法可以是，通过人脸识别技术，识别图像中的人脸图像，若能够识别完整的人脸图像，则判定用户正在注视屏幕；或者通过识别人脸图像中是否具有用户的眼睛的图像或者双眼的图像，若有，则判定用户正在注视屏幕；当然也可根据实际需求来进行设计，而不采用前述两种方法；
步骤105：若判定用户正在注视屏幕，则退出待机状态并进入正常工作状态，此时，用户即可正常使用移动终端。
从上述实施例可以看出，本发明提供的待机状态控制方法，通过在待机状态判断是否发生预开机动作，若发生预开机动作则开启前置摄像头并采集图像，通过图像内容判定用户是否正在注视移动终端的屏幕，从而判定用户此时需要使用移动终端，接着使移动终端自动切换为正常工作状态，使得用户不通过手动开机即可开始使用移动终端，方便了用户的操作，提升了用户体验。
进一步的，在一些可选实施方式中，所述持续采集所述加速度传感器产生的加速度数据的步骤101之前还可包括以下步骤：
判断移动终端当前所处状态，例如，判断是正常工作状态，亦或是待机状态；
若处于正常工作状态，则开启所述前置摄像头；
根据所述前置摄像头采集的图像，判断用户是否正在注视屏幕；
若用户未注视屏幕，则持续监测用户未注视屏幕的状态并开始计时；
判断计时时长是否达到预设待机时限；
若达到预设待机时限，则退出正常工作状态并进入待机状态；
若在未达到预设待机时限时，又监测到用户正在注视屏幕，则进行保持正常工作状态。
其中，所述预设待机时限可以是系统默认的时长，也可以是用户自定义设置的时长；用户是否正在注视屏幕的判断方法可以采用上述实施例中的方式，在此不再赘述。
这样，通过判断用户是否注视屏幕来得出用户是否正在使用移动终端，使得移动终端在不被用户使用，例如搁置于桌面，且在用户不使用移动终端的时长达到预设待机时限时，自动进入待机状态，而无需用户手动进行待机控制，一方面简化了用户操作，另一方面节约了移动终端的电量。
较佳的，在一些可选实施方式中，所述开启所述前置摄像头的步骤103之后还包括以下步骤：
发出提醒用户注视所述前置摄像头的提示信息；如图4所示，提示信息401发出后的移动终端屏幕400的显示示意图。
通过设置提示信息401，使得当需要进一步通过前置摄像头判定用户是否在注视屏幕时，提醒用户注视摄像头可开启手机，从而引导用户的操作，提升用户体验。
可选的，在一些实施方式中，所述根据所述前置摄像头采集的图像，判断用户是否正在注视屏幕的步骤104具体可包括以下步骤：
判断所述前置摄像头采集的图像中是否有眼睛图像；这里，需先对前置摄像头采集的图像进行人脸识别，从中提取出人脸图像，再从人脸图像中提取眼睛图像；但是，若能够直接从前置摄像头采集的图像中提取出眼睛图像，则可跳过人脸识别的步骤；
若有眼睛图像，则判定用户正在注视屏幕；
若没有眼睛图像，则判定用户未注视屏幕；
通过判断前置摄像头采集的图像中是否有眼睛图像来判断用户是否在注视屏幕，从而能够更加准确的推断出用户当前的使用状态。
可选的，在另一些实施方式中，所述根据所述前置摄像头采集的图像，判断用户是否正在注视屏幕的步骤104之前还包括：
在预设采集时间内，利用所述前置摄像头采集图像；
所述根据所述前置摄像头采集的图像，判断用户是否正在注视屏幕的步骤104具体可包括：
判断所述预设采集时间的预设最后时段内采集的图像中是否持续出现眼睛图像；这里，同样的，需先对前置摄像头采集的图像进行人脸识别，从中提取出人脸图像，再从人脸图像中提取眼睛图像；但是，若能够直接从前置摄像头采集的图像中提取出眼睛图像，则可跳过人脸识别的步骤；
若持续出现眼睛图像，则判定用户正在注视屏幕；
若没有持续出现眼睛图像，则判定用户未注视屏幕。
其中，预设采集时间为默认的或自定义的预设采集时间，预设最后时段是预设采集时间的最后时段，二者的数据可根据实际需要任意设置，例如，预设采集时间是0.5秒或1秒，预设最后时段是0.3秒或0.5秒等，这种设置方式主要是考虑到用户在拿起移动终端时前置摄像头即自动开启，这时在起初的时刻用户还没开始注视屏幕，因此，在预设最后时段采集的图像更能说明用户是否在注视屏幕。
通过判断在预设采集时间的预设最后时段前置内摄像头采集的图像中是否有眼睛图像来判断用户是否在注视屏幕，从而能够更加准确的推断出用户当前的使用状态。
此外，在上述实施例中，除了直接判断摄像头采集的图像中是否有眼睛图
像外，还可通过眼睛图像来判断眼睛与屏幕距离、视线焦点等，从而更加准确地判断出用户的使用状态。
进一步的，在一些可选实施方式中，所述根据所述加速度数据，判断是否发生预开机动作的步骤102还可具体包括以下步骤：
根据所述加速度数据，判断是否发生加速度变化；
若发生加速度变化，则判断发生加速度变化的时刻所产生的加速度的垂直分量是否大于预设垂直分量阈值；所述预设垂直分量阈值可以是默认的或自定义的加速度值，可根据实际需要进行设置；
若大于所述预设垂直分量阈值，则判定发生所述预开机动作；
通过判断加速度变化的垂直分量，推断出用户是正在拿起移动终端，从而预测用户需要开启移动终端，接着开启摄像头进一步准确判断。
在一些时候，用户可能正携带着移动终端运动(走路、跑步等等)，这时用户并不需要使用移动终端，因此需要剔除这部分数据。
因此，在另一些可选实施方式中，所述根据所述加速度数据，判断是否发生预开机动作的步骤102还可具体包括以下步骤：
根据所述加速度数据，判断是否发生加速度变化；
若发生加速度变化，判断发生加速度变化后的预设加速度计算时段内采集的加速度的垂直分量的平均值是否大于预设垂直分量阈值且最后时刻的垂直分量的方向是否向上；所述预设加速度计算时段可以是默认的或自定义的一段时长，例如5秒；所述预设垂直分量阈值可以是默认的或自定义的加速度值，可根据实际需要进行设置；
若大于所述预设垂直分量阈值且最后时刻的垂直分量的方向向上，则判定发生所述预开机动作。
通过判断发生加速度变化后的预设加速度计算时段内采集的加速度的垂直分量的平均值是否大于预设垂直分量阈值且最后时刻的垂直分量的方向是否向
上，能够更加准确地推断出用户是正在拿起移动终端而不是正在走路，从而预测用户需要移动终端，接着开启摄像头进一步准确判断。
下面介绍所述待机状态控制方法的另一个实施例，如图2所示，为本发明提供的待机状态控制方法的另一个实施例的流程示意图。
所述待机状态控制方法，包括以下步骤：
步骤201：判断移动终端当前所处状态，例如，判断是正常工作状态，亦或是待机状态；
步骤202：若处于正常工作状态，则开启所述前置摄像头；
步骤203：根据所述前置摄像头采集的图像，判断用户是否正在注视屏幕；
步骤204：若用户正在注视屏幕，则继续保持正常工作状态；
步骤205：若用户未注视屏幕，则持续监测用户未注视屏幕的状态并开始计时；
步骤206：判断计时时长是否达到预设待机时限；
步骤207：若达到预设待机时限，则退出正常工作状态并进入待机状态；
步骤208：若在未达到预设待机时限时，又监测到用户正在注视屏幕，则继续保持正常工作状态；
步骤209：若处于待机状态，则持续采集所述加速度传感器产生的加速度数据；
步骤210：根据所述加速度数据，判断是否发生预开机动作；
步骤211：若未发生所述预开机动作，则继续采集所述加速度传感器产生的加速度数据；
步骤212：若发生所述预开机动作，则开启所述前置摄像头；
步骤213：发出提醒用户注视所述前置摄像头的提示信息；
步骤214：根据所述前置摄像头采集的图像，判断用户是否正在注视屏
幕；
步骤215：若用户正在注视屏幕，则退出待机状态并进入正常工作状态。
步骤216：若用户未注视屏幕，则关闭前置摄像头并继续采集所述加速度传感器产生的加速度数据。
从上述实施例可以看出，本发明提供的待机状态控制方法，通过在正常工作状态判定用户是否离开屏幕跟前，从而在确定用户未使用时，自动进入待机状态，方便了用户的操作，节省了移动终端的电量，提升了用户体验；同时，通过在待机状态判断是否发生预开机动作，若发生预开机动作则开启前置摄像头并采集图像，通过图像内容判定用户是否正在注视移动终端的屏幕，从而判定用户此时需要使用移动终端，接着使移动终端自动切换为正常工作状态，使得用户不通过手动开机即可开始使用移动终端，方便了用户的操作，提升了用户体验。

- 根据权利要求6所述的移动终端，其特征在于，所述移动终端还包括：状态判断模块，用于判断当前所处状态；若处于正常工作状态，所述摄像头启动模块还用于开启所述前置摄像头；所述用户状态判断模块，用于根据所述前置摄像头采集的图像，判断用户是否正在注视屏幕；状态监测与计时模块，若用户未注视屏幕，用于持续监测用户未注视屏幕的状态并开始计时；待机时限判断模块，用于判断计时时长是否达到预设待机时限；若达到预设待机时限，所述状态切换模块还用于退出正常工作状态并进入待机状态。
- 根据权利要求6所述的移动终端，其特征在于，还包括提示模块，用于发出提醒用户注视所述前置摄像头的提示信息。
- 根据权利要求6-8任意一项所述的移动终端，其特征在于，所述用户状态判断模块，具体用于：判断所述前置摄像头采集的图像中是否有眼睛图像；若有眼睛图像，则判定用户正在注视屏幕；若没有眼睛图像，则判定用户未注视屏幕；或者，所述用户状态判断模块，具体用于：在预设采集时间内，利用所述前置摄像头采集图像；判断所述预设采集时间的预设最后时段内采集的图像中是否持续出现眼睛图像；若持续出现眼睛图像，则判定用户正在注视屏幕；若没有持续出现眼睛图像，则判定用户未注视屏幕。
- 根据权利要求6-8任意一项所述的移动终端，其特征在于，所述预开机动作判断模块，具体用于：根据所述加速度数据，判断是否发生加速度变化；若发生加速度变化，则判断发生加速度变化的时刻所产生的加速度的垂直分量是否大于预设垂直分量阈值；若大于所述预设垂直分量阈值，则判定发生所述预开机动作；或者，所述预开机动作判断模块，具体用于：根据所述加速度数据，判断是否发生加速度变化；若发生加速度变化，判断发生加速度变化后的预设加速度计算时段内采集的加速度的垂直分量的平均值是否大于预设垂直分量阈值且最后时刻的垂直分量的方向是否向上；若大于所述预设垂直分量阈值且最后时刻的垂直分量的方向向上，则判定发生所述预开机动作。
