背景技术
在全面屏终端的设计中，为了避免前置摄像头影响终端的屏占比，相关技术中的解决方案是将前置摄像头设计成升降式的。当需要进行前置拍照时，通过终端内部的驱动机构驱动摄像头，使摄像头升出终端的壳体，在保证终端屏占比的同时完成拍照。
上述解决方案带来了新的问题，由于用户在使用终端进行拍照时都会经过“摄像头升起-进行拍照-拍照结束-摄像头收回”的过程，在该过程中，均需要驱动机构驱动摄像头的升起与下降。当用户多次进行拍照时，驱动机构频繁工作，使得终端的耗电量明显增加，导致终端的使用时间减少。

具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，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，都属于本公开保护的范围。
本公开实施例中的终端可以是手机、平板电脑、笔记本电脑、掌上电脑、车载终端、可穿戴设备、以及计步器等，该终端包括但不限于：摄像头、用于驱动摄像头升起或下降的驱动机构和显示屏，该驱动机构能够驱动摄像头沿预定方向往复移动，使该摄像头具有两种工作状态：升起状态和收回状态。
需要说明的是，上述终端可以包括多个摄像头，在该多个摄像头中至少有一个摄像头能够在驱动机构的驱动下进行升降，例如：该终端为全面屏的手机，包括一个前置摄像头和一个后置摄像头，其中前置摄像头和/或后置摄像头能够在驱动机构的驱动下进行升降。以前置拍照为例，当用户使用全面屏的手机进行前置拍照时，该前置摄像头处于升起状态。
参见图1，本公开实施例提供了一种摄像头控制方法，应用于终端，具体步骤如下：
步骤101：获取终端的剩余电量；
步骤102：当终端的剩余电量符合预设条件，且终端满足摄像头升降条件时，控制摄像头维持在升起状态或收回状态。
在本公开实施例中，预设条件为终端的剩余电量小于或等于预设的电量门限值。摄像头升降条件是指摄像头有升降需求的条件，例如：当用户打开视频聊天应用程序时，需要摄像头升起，则开启视频聊天应用程序为摄像头升降条件，本公开实施例对摄像头升降条件的内容不做具体限定。
本公开实施例中，当终端剩余电量符合预设条件，且终端满足摄像头升降条件时，终端的摄像头将维持升起状态或收回状态，避免因摄像头频繁升起或下降而增加终端的耗电量。
驱动机构的工作模式包括：第一工作模式和第二工作模式，其中第一工作模式是指驱动机构不响应驱动摄像头下降或升起的控制指令的工作模式；第二工作模式是指驱动机构能够响应驱动摄像头下降或升起的控制指令的工 作模式。
以该摄像头为前置摄像头，且驱动机构进入第一工作模式时摄像头的工作状态为升起状态为例。该场景对应于用户对前置拍照的需求较高，当用户进行前置拍照或者使用前置摄像的应用程序时，由于摄像头已经处于升起状态，摄像头能够直接开始工作。当用户完成拍照或者关闭需要前置摄像的应用程序时，驱动机构会接收到驱动摄像头下降的控制指令，但是，由于驱动机构处于第一工作模式，并不会响应该驱动摄像头下降的控制指令，摄像头的工作状态继续处于升起状态。这样，通过不响应驱动摄像头下降的控制指令，使摄像头能够基于当前升起状态直接开始工作，避免了驱动机构多次驱动摄像头升降，减少了终端的耗电量。
以该摄像头为前置摄像头，且驱动机构进入第一工作模式时摄像头的工作状态为收回状态为例。该场景对应于用户对前置拍照的需求较低，当用户由于误操作触碰了终端自带的前置拍照的开关时，驱动机构会接收到驱动摄像头升起的控制指令，但是，由于驱动机构处于第一工作模式，并不会响应该控制指令，摄像头的工作状态将保持为收回状态。
类似的，当用户由于误操作打开了需要前置摄像的应用程序，例如：具有视频聊天功能的应用程序，驱动机构不会响应驱动摄像头升起的控制指令。这样，通过不响应驱动摄像头升起的控制指令，避免由于用户误操作导致驱动机构工作，防止不必要的电量消耗。
本公开实施例中，驱动机构在第一工作模式下可以不响应驱动摄像头下降或升起的控制指令，使得摄像头可以一直保持升起状态或收回状态工作，避免因驱动机构频繁驱动摄像头升起或下降而增加终端的耗电量。
本公开实施例提供了另一种摄像头控制方法，应用于终端，该终端还包括用于驱动所述摄像头升起或下降的驱动机构，该驱动机构的工作模式包括：第一工作模式和第二工作模式，第一工作模式是指驱动机构不响应驱动摄像头下降或升起的控制指令的工作模式，第二工作模式是指驱动机构能够响应驱动摄像头下降或升起的控制指令的工作模式。
参见图2，该方法的具体步骤如下：
步骤201：获取终端的剩余电量；
步骤202：当终端的剩余电量小于或等于第一电量门限值，且终端满足摄像头升降条件时，控制驱动机构进入第一工作模式，由驱动机构控制摄像头维持在升起状态或收回状态。
在本公开实施例中，终端的剩余电量小于或等于第一电量门限值时，表示此时终端的电量较低，终端需要控制驱动机构进入第一工作模式。
其中，第一电量门限值可以是终端内预存的电量门限值，或者第一电量门限值也可以是用户自己设置的电量门限值，例如：该第一电量门限值可以是50％，本公开实施例对第一电量门限值的数值不做具体限定。
本公开实施例中，当终端的剩余电量小于或等于第一电量门限值时，控制驱动机构进入第一工作模式，使摄像头维持升起状态或收回状态工作，避免因驱动机构频繁驱动摄像头升起或下降而增加终端的耗电量。
参见图3，本公开实施例提供了另一种摄像头控制方法，应用于终端，该方法的具体步骤如下：
步骤301：获取终端的剩余电量；
步骤302：当终端的剩余电量小于或等于第一电量门限值，且终端满足摄像头升降条件时，控制驱动机构进入第一工作模式，由驱动机构控制摄像头维持在升起状态或收回状态；
上述步骤301和步骤302可以参照图2中的步骤201和步骤202，在此不再赘述。
步骤303：在显示屏上显示提示信息，然后执行步骤304或者步骤305；
在本公开实施例中，提示信息用于提示是否调整所述摄像头的工作状态，该提示信息可以是以悬浮窗的形式显示在显示屏中，可以理解的是，该提示信息可以显示在显示屏的中部、顶部或者底部，本公开实施例对提示信息的表现形式以及在显示屏中的显示位置不做具体限定。
参见图4a，在显示屏41的中部显示悬浮窗42，该悬浮窗42中包含提示信息的内容，该提示信息的内容可以是“是否调整摄像头的工作状态”，本公开实施例对提示信息的内容不做具体限定。
步骤304：响应于调整摄像头的工作状态的第一操作，控制驱动机构进入第二工作模式，并通过驱动机构驱动摄像头升起，将摄像头的工作状态调 整为升起状态，然后执行步骤309；
步骤305：响应于调整摄像头的工作状态的第一操作，控制驱动机构进入第二工作模式，并通过驱动机构驱动摄像头下降，将摄像头的工作状态调整为收回状态，然后执行步骤306；
在本公开实施例中，第一操作可以是在显示屏上的双击操作，或者，第一操作也可以是在显示屏上的滑动操作，第一操作可以作用在显示中显示提示信息的位置，第一操作也可以作用在显示中的其它位置，本公开实施例对第一操作的具体形式与第一操作作用在显示屏中的具体位置不做限定。
当终端接收到用户的第一操作时，先控制驱动机构进入第二工作模式，终端根据摄像头当前的工作状态，通过驱动机构驱动摄像头升起或下降，将摄像头的工作状态由收回状态调整为升起状态，或者由升起状态调整为收回状态。
具体地，参见图4b，本公开实施例提供一种应用场景，以摄像头当前的工作状态为收回状态为例，终端接收到用户的第一操作后，控制驱动机构进入第二工作模式，由于摄像头43的工作状态为收回状态，通过驱动机构驱动摄像头升起，将摄像头43的工作状态由收回状态调整为升起状态。
类似地，对于摄像头当前的工作状态为升起状态的情况，可以参照图4b的描述，在此不再赘述。
为了避免误操作，在本公开实施例中第一操作可以是具有特定轨迹的滑动操作。
参见图4c，本公开实施例提供另一种应用场景，以摄像头当前的工作状态为收回状态为例，第一操作是滑动轨迹为圆形的滑动操作，终端接收到用户的第一操作后，控制驱动机构进入第二工作模式，由于摄像头43的工作状态为收回状态，通过驱动机构驱动摄像头升起，将摄像头43的工作状态由收回状态调整为升起状态。
类似地，对于摄像头当前的工作状态为升起状态的情况，可以参照图4c的描述，在此不再赘述。
步骤306：在将摄像头的工作状态调整为收回状态之后，控制驱动机构进入第一工作模式，然后执行步骤307；
避免由于用户误操作导致驱动机构工作，防止不必要的电量消耗。
步骤307：在显示屏中显示用于切换摄像头的工作状态的虚拟开关，然后执行步骤308；
步骤308：响应于对虚拟开关的第二操作，控制驱动机构进入第二工作模式，通过驱动机构驱动摄像头升起，将摄像头的工作状态调整为升起状态，然后执行步骤309；
为了满足用户的拍照需求，可以对驱动机构的工作模式进行调整。参见图4d，当摄像头43的工作状态被调整为收回状态时，在显示屏41中生成用于切换摄像头43的工作状态的虚拟开关45。可以理解的是，该虚拟开关45可以显示在显示屏41的中部、顶部或者底部，本公开实施例对虚拟开关45在显示屏41中的显示位置不做具体限定。
当用户需要使用摄像头43进行拍照时，可以通过对该虚拟开关的第二操作，控制驱动机构进入第二工作模式，并将摄像头的工作状态切换为升起状态。
上述第二操作可以是在虚拟开关45上的双击操作，或者，第二操作也可以是在虚拟开关45上的长按操作(例如：长按操作的按压时间为1～2秒)，本公开实施例对第二操作的具体形式不做限定。
步骤309：在将摄像头的工作状态调整为升起状态之后，控制驱动机构进入第一工作模式；
本公开实施例中，终端输出用于提示是否调整摄像头的工作状态的提示信息，并响应用户的第一操作，将摄像头的工作状态调整为升起状态或收回状态；此外，当摄像头的工作状态调整为收回状态时，终端还在显示屏中显示用于切换摄像头的工作状态的虚拟开关，通过响应用户的第二操作，将摄像头的工作状态切换为升起状态，使用户能够灵活得调整终端的拍照模式以及摄像头的工作状态，在减少终端的耗电量的同时，提高了使用体验。
参见图5，本公开实施例还提供了一种摄像头控制方法，应用于终端，该方法的具体步骤如下：
步骤501：获取终端的剩余电量；
步骤502：当终端的剩余电量小于或等于第一电量门限值，且终端满足 摄像头升降条件时，控制驱动机构进入第一工作模式，由驱动机构控制摄像头维持在升起状态或收回状态；
上述步骤502可以参照图2中的步骤202，在此不再赘述。
步骤503：当终端的剩余电量小于或等于第二电量门限值，且摄像头的工作状态为升起状态时，控制驱动机构进入第二工作模式；
在本公开实施例中，第二电量门限值小于第一电量门限值，该第二电量门限值可以是终端内预存的电量门限值，或者第二电量门限值也可以是用户自己设置的电量门限值，例如：该第二电量门限值可以是10％，本公开实施例对第二电量门限值的数值不做具体限定。
当第二剩余电量小于或等于第二电量门限值，表示此时终端的电量即将耗尽。终端在电量即将耗尽时，通常采取自动关机并对摄像头进行初始化，以保护摄像头，避免受到外界磕碰。若此时摄像头的工作状态为升起状态，则终端控制驱动机构进入第二工作模式，驱动机构在第二工作模式下能够响应驱动摄像头下降的控制指令。
可以理解的是，当终端的剩余电量小于或等于第二电量门限值，且摄像头的工作状态为收回状态时，由于摄像头已经收回，不需要控制驱动机构进入第二工作模式。
步骤504：通过驱动机构驱动摄像头下降，使得摄像头的工作状态调整为收回状态。
本公开实施例中，当终端的剩余电量低于第二电量门限值，且摄像头的工作状态为升起状态时，控制驱动机构进入第二工作模式，使驱动机构能够响应驱动摄像头下降的控制指令，使摄像头的工作状态切换为收回状态，保护摄像头，延长摄像头的使用寿命。
