实施例1
图1是本发明实施例1提供的一种摄像头升降控制方法的流程图，该方 法应用于设置有升降摄像头的移动终端，所述移动终端在预设位置设置有霍尔传感模块，包括上霍尔传感器以及下霍尔传感器，所述升降摄像头具有磁性，所述上霍尔传感器以及下霍尔传感器所在直线平行于所述升降摄像头升降方向；包括如下步骤：
步骤S11：当控制所述升降摄像头升降时，开启所述霍尔传感模块，利用所述霍尔传感模块采集所述升降摄像头运动过程中的磁感应强度。
本发明实施例中，为了使移动终端拥有百分之百的屏占比，也即实现全面屏，移动终端的前置摄像头可以设置在移动终端的内部，利用升降装置驱动摄像头从移动终端的一侧弹出，在不需要使用的时候收回移动终端内部，也即为升降摄像头。其中，升降摄像头进行升降的过程采用步进电机来驱动，也即在用户将移动终端的摄影模式调至前置摄像模式时，升降摄像头的步进电机将驱动该摄像头进行升起，在关闭前置摄像头或切换至其它不需要使用前置摄像头的模式时，可以驱动步进电机下降该摄像头，将摄像头收回移动终端内部。
本发明实施例中，所述霍尔传感模块包括上霍尔传感器以及下霍尔传感器；所述上霍尔传感器和所述下霍尔传感器所在直线平行于所述升降摄像头的升降方向；所述上霍尔传感器与所述下霍尔传感器之间有预设间隔。
本发明实施例中，如图2以及图3所示，该移动终端200的预设位置中设置有霍尔传感模块210，该霍尔传感模块210的位置固定，而活动的升降摄像头230上设置有磁铁220，该磁铁220可以为永久磁铁，或者是电磁铁，在进行摄像头的升降时激活，这里不做限定。其中，该霍尔传感模块210包括上霍尔传感器211以及下霍尔传感器212，该上霍尔传感器211在所述升降摄像头230完全上升时检测的磁感应强度最强，在升起所述升降摄像头230时，利用该上霍尔传感器211采集磁感应强度；该下霍尔传感器212在所述升降摄像头230完全下降时检测的磁感应强度最强，在下降所述升降摄像头230时，利用该下霍尔传感器212采集磁感应强度。也即上霍尔传感器211 与下霍尔传感器212可以设置在升降摄像头230的一侧，其上霍尔传感器211与下霍尔传感器212之间的间隔刚好是升降摄像头230所能移动的最大距离，在摄像头完全升起时磁铁的中心点与上霍尔传感器211的中心点在一条水平线上，而在摄像头完全下降时磁铁的中心点与下霍尔传感器212的中心点在一条水平线上。
本发明实施例中，当移动终端的升降摄像头开始升起或下降时，该霍尔传感模块启动，具体的，在摄像头升起时可以仅开启上霍尔传感器，在摄像头下降时可以仅开启下霍尔传感器，以降低移动终端的能耗。同时，无论升起或下降摄像头，该上霍尔传感器以及下霍尔传感器均可同时开启，以提高检测摄像头移动的精确度。
步骤S12：根据所述磁感应强度以及预设条件判断所述升降摄像头是否完全升起或完全下降。
本发明实施例中，在通过霍尔传感模块实时采集升降摄像头上磁铁的磁感应强度后，该移动终端可以根据预设条件以及实时的磁感应强度进行摄像头是否完全升起或完全下降的判断，具体地，例如可以在升起摄像头时利用上霍尔传感器实时采集磁感应强度，当磁感应强度等于或超过预设值一段时间后，则可确定该摄像头已经完全升起；在下降摄像头时利用下霍尔传感器实时采集磁感应强度，当磁感应强度等于或超过预设值一段时间后，则确定该摄像头完全下降。
步骤S13：当所述升降摄像头完全升起或完全下降时，关闭带动所述升降摄像头升降的步进电机。
本发明实施例中，上述根据磁感应强度以及预设条件进行摄像头完全升降判断的过程可以利用算法或应用程序来实现，例如可以在移动终端中设置有应用程序，该应用程序接收上霍尔传感器或下霍尔传感器采集的磁感应强度，并利用该磁感应强度与预设强度值进行比较，在等于或超过预设值一段时间后生成关闭指令发送至驱动摄像头升降的步进电机。通过上述方法步骤， 可以在摄像头完全升起或者完全下降后及时关闭驱动摄像头升降的步进电机，避免步进电机因空转产生故障，提高升降摄像头的寿命，并且避免步进电机空转产生噪音，提高用户体验度。
实施例2
图4是本发明实施例2提供的一种摄像头升降控制方法的流程图，该方法应用于设置有升降摄像头的移动终端，所述移动终端在预设位置设置有霍尔传感模块，包括上霍尔传感器以及下霍尔传感器，所述升降摄像头具有磁性，所述上霍尔传感器以及下霍尔传感器所在直线平行于所述升降摄像头升降方向；包括如下步骤：
步骤S41：当控制所述升降摄像头升降时，开启所述霍尔传感模块，利用所述霍尔传感模块采集所述升降摄像头运动过程中的磁感应强度。
此步骤与上述步骤S11一致，在此不再赘述。
步骤S42：根据所述磁感应强度判断所述升降摄像头是否升降到预设减速位置。
步骤S43：当所述升降摄像头升降到预设减速位置时，降低所述步进电机的速度至预设速度。
本发明实施例中，还可以根据磁感应强度判断升降摄像头是否升降到预设减速位置，从而进行步进电机的减速。具体的，可以在移动终端出厂前记录减速点的磁感应强度，例如在升起过程中，距离完全升起还有0.3mm时为减速点，记录该减速点的磁感应强度。步进电机在减速后，可以降低摄像头移动至终端后的抖动，从而降低噪音，提高用户体验度。
步骤S44：根据所述磁感应强度以及预设条件判断所述升降摄像头是否完全升起或完全下降。
此步骤与上述步骤S12一致，在此不再赘述。
步骤S45：当所述升降摄像头完全升起或完全下降时，关闭带动所述升 降摄像头升降的步进电机。
此步骤与上述步骤S13一致，在此不再赘述。
图5是本发明实施例2提供的一种判断摄像头完全升降的流程图，包括如下步骤：
步骤S51：确定当前时刻磁感应强度与前一时刻磁感应强度的差值，判断所述差值是否在预设差值范围内出现两次。
步骤S52：当所述差值在预设差值范围内出现两次时，确定所述升降摄像头完全升起或完全下降。
本发明实施例中，在升降摄像头进行升降的过程中，霍尔传感器采集的磁感应强度使逐渐递增的，知道完全升降为止，也即可以根据前后两次采集的磁感应强度来判断摄像头是否完全升降至终点。具体地，在升降摄像头升起的过程中，利用上霍尔传感器采集磁感应强度，在升降摄像头升起至终点时，由于步进电机的空转，将导致升降摄像头上下抖动，因此可以判断短时间内前后磁感应强度的差值是否在预设范围内至少出现两次，如果出现两次则说明升降摄像头完全升起并在抖动状态。同时，在理想状态下如果摄像头完全升起后不抖动，则磁感应强度则不改变，也即上述差值为零，因此差值为零也可以作为一种判断的基准，这里不做限定。
本发明实施例中，由于升降摄像头的抖动非常小，因此磁感应强度的变化也比较小，因此预设差值范围可以设置一个比较小的范围，例如可以设置为(-3,3)，这里不做限定。
图6是本发明实施例2提供的另一种判断摄像头完全升降的流程图，包括如下步骤。
步骤S61：判断当前时刻磁感应强度是否比前一时刻磁感应强度小。
步骤S62：在当前时刻磁感应强度比前一时刻磁感应强度小时，确定所 述升降摄像头完全升起或完全下降。
本发明实施例中，在当前的磁感应强度是否比前一时刻磁感应强度小，则说明摄像头升降完全，其原理同样是利用了摄像头完全升降后步进电机使摄像头处于抖动的状态，这时候摄像头将会上下抖动。如果为完全升起状态时向下抖动，或者是完全下井状态时向上抖动，则会产生磁感应强度下降的情况，这时则可以确定所述升降摄像头完全升起或完全下降。
图7是本发明实施例2提供的另一种判断摄像头完全升降的流程图，包括如下步骤。
步骤S71：在所述升降摄像头升起时，判断当前时刻磁感应强度是否大于第一预设磁感应强度值。
步骤S72：在当前时刻磁感应强度大于第一预设磁感应强度值时，确定所述升降摄像头完全升起。
步骤S73：在所述升降摄像头下降时，判断当前时刻磁感应强度是否大于第二预设磁感应强度值。
步骤S74：在当前时刻磁感应强度大于第二预设磁感应强度值时，确定所述升降摄像头完全下降。
本发明实施例中，在移动终端出厂前，还可以为其设置一个预设磁感应强度，根据该预设磁感应强度判断是否完全升起或完全下降。例如在出厂前进行摄像头的升降测试，在升起过程中，在摄像头上升至15％时记录为第一磁感应强度值，在上升至85％时记录为第二磁感应强度值，其中第一磁感应强度值用于判断完全下降，第二磁感应强度值用于判断完全上升。
其中，上述三种判断摄像头完全升降的方法还可以应用在步进电机不设置减速的情况下，这里不做限定。
本发明实施例中，在降低步进电机的速度至预设速度后，也即摄像头经 过减速点后，还可以根据减速后升降的距离以及步进电机速度判断摄像头是否完全升降，具体的，可以根据预设速度以及减速点计算出理论上从减速点开始至完全升降的时间，将该时间的两倍作为预设时间值，则可根据以下步骤判断完全升降：从预设减速位置开始记录所述升降摄像头的升降时间；判断所述升降时间是否大于预设时间值；在所述升降时间大于预设时间值时，确定所述升降摄像头完全升起或完全下降。
本发明实施例中，该预设时间值只要比利用减速点的位置以及减速后的速度计算出的理论时间值大即可，这里不做限定。
