下面参考附图描述本发明实施例的摄像模组控制方法和装置。
为了更加清楚的描述本发明实施例的摄像模组控制方法，下面首先对本发明的电子装置进行结构上的描述。
具体地，为了降低摄像模组等安装在电子装置前置面板上的硬件设备对屏幕占比的影响，本发明提出了一种滑动组件，通过滑动组件的滑动控制摄像模组等在需要的时候滑出，在不需要的时候收容于电子装置本体内，由此，在不进行摄像模组等组件的功能服务时，使其不占用电子装置前置面板。
具体而言，如图1-图4所示，本发明实施例的电子装置100包括本体10、滑动组件20和驱动组件50。滑动组件20用于在收容于本体10的第一位置A和自本体10露出的第二位置B之间滑动。驱动组件50用于驱动滑动组件20在收容于本体的第一位置和自本体露出的第二位置之间滑动。
当然，为了使得驱动组件50获知驱动滑动组件20滑动至相应位置，该电子装置中还必然包括检测滑动组件20当前位置的检测组件30，在本发明的实施例中，检测组件30用于检测滑动组件20的位置，检测组件30包括磁场产生元件32、霍尔元件34和处理器60，磁场产生元件32和霍尔元件34分别固定在本体10和滑动组件20上，处理器60用于接收霍尔元件34输出的检测信号值，以及用于根据检测信号值确定滑动组件20相对于本体10的当前相对位置。
值得注意的是，此处“磁场产生元件32和霍尔元件34分别固定在本体10和滑动组件20上”包括两种情况，一是磁场产生元件32固定在本体10上，霍尔元件34固定在滑动组件20上，二是磁场产生元件32固定在滑动组件20上，霍尔元件34固定在本体10上。此外，磁场产生元件32和霍尔元件34可以在竖直方向上相对放置，也可以在水平方向上相对放置。也即是说，只要磁场产生元件32和霍尔元件34可以产生相对运动，不对磁场产生元件32和霍尔元件34的具体位置做限制。
在某些实施方式中，本体10形成有滑槽16，滑动组件20在第一位置A时收容于滑槽16内。如此，可以使得滑动组件20通过滑槽16在第一位置A和第二位置B之间滑动。
具体地，本体10包括壳体12和显示组件14，壳体12和显示组件14组合在一起构成封闭式结构。滑槽16开设在壳体12，从而实现滑动组件20的滑回与滑出。可以理解，滑槽16可以开设在壳体12的任意一条侧边。优选地，滑槽16开设在壳体12的顶边。如此可以符合用户的使用习惯。
显示组件14包括触控面板(图未示)和盖板142。触控面板包括显示模组(图未示)和设置在显示模组上的触控层(图未示)。显示模组例如为液晶显示模组(LCD Module，LCM)，当然，显示模组也可以为柔性的显示模组。触控层用于接收用户的触控输入，以产生用于控制显示模组显示的内容的信号和控制滑动组件20滑动的信号。
盖板142的材料可以由玻璃、陶瓷或蓝宝石等透光材料制成。由于盖板142由于作为电子装置100的输入零件，盖板142经常受到碰撞或刮划等接触。例如，用户将电子装置100放入口袋时，盖板142可能被用户口袋中的钥匙刮划而损伤。因此，盖板142的材料可以采用硬度较大的材料，例如以上的蓝宝石材料。或者在盖板142的表面形成硬化层以提高盖板142的抗刮能力。
触控面板与盖板142例如通过光学胶(Optically Clear Adhesive，OCA)粘接固定在一起，光学胶不仅粘接固定触控面板及盖板142，还可以透过触控面板发出的光线。
为了更加清楚的说明本发明实施例的滑动组件20的功能，参照图5，当在某些实施方式中，电子装置100包括摄像模组42，滑动组件20包括承载件22，摄像模组42设置在承载件22上。如此，摄像模组42可以随着滑动组件20滑动。当然，可以将用户打开摄像模组42和关闭摄像模组42作为触发信号，也即是说，当用户打开摄像模组42时，触发滑动组件20滑出，当用户关闭摄像模组42时，触发滑动组件20滑回。如此用户只需依照现有的习惯打开或关闭摄像模组，而无需针对滑动组件20进行另外的操作，可以方便用户的使用。
除摄像模组42之外，承载件22上也可以承载其他的功能器件40，功能器件40比如为光线传感器、接近传感器和听筒44等，如图1所示。这些功能器件40可以根据用户的输入随着滑动组件20的滑出而从本体10露出从而正常工作，也可以根据用户的输入随着滑动组件20的滑回而收容在本体10内。如此，可以尽量少地在显示组件14上设置通孔，有利于满足电子装置100全面屏的设计需求。
具体地，当承载件22上承载有光线传感器时，可以将光线传感器设置在承载件22的顶部，也即是说，当滑动组件20完全收容于滑槽16内时，光线传感器依旧可以从承载件22的顶部露出，从而实时感应光线。
请参阅图6，当承载件22上承载有接近传感器和听筒44时，可以将用户接听电话和挂断电话作为触发信号，也即是说，当用户接听电话时，触发滑动组件20滑出，当用户挂 断电话时，触发滑动组件20滑回。如此用户只需依照现有的习惯接听或挂断电话，而无需针对滑动组件20进行另外的操作，可以方便用户的使用。
可以理解，多个功能器件40可以承载在同一个承载件22上，也可以承载在多个承载件上。当多个功能器件40承载在同一个承载件22上时，多个功能器件40可以纵向排列，处理器60可以通过控制滑动组件20滑出的距离控制设置在承载件22下部的功能器件40是否露出。当多个功能器件40承载在同多个承载件22上时，处理器60可以通过控制某个承载件22的滑动从而选择需要露出的功能器件40。
请参阅图7，在某些实施方式中，滑动组件20包括设置在承载件22中部的螺纹孔24和与螺纹孔24配合的转动丝杆26。滑槽16包括与螺纹孔24相对设置且位于滑槽16底部的凹槽162。电子装置100包括设置在凹槽162的驱动组件50。驱动组件50包括与处理器60连接的驱动电机52和与转动丝杆26的底部连接的输出轴(图未示)。
可以理解，处理器60可以通过控制驱动电机52来控制滑动组件20的滑动。当用户命令滑动组件20从第一位置A向第二位置B滑动时，处理器60控制驱动电机52正转，从而使得输出轴带动转动丝杆26在螺纹孔24内转动，进而使得滑动组件20从第一位置A向第二位置B滑动。当用户命令滑动组件20从第二位置B向第一位置A滑动时，处理器60控制驱动电机52反转，从而使得输出轴带动转动丝杆26在螺纹孔24内转动，进而使得滑动组件20从第二位置B向第一位置A滑动。值得注意的是，此处的“从第一位置A向第二位置B”和“从第二位置B向第一位置A”是指滑动的方向，而不是指滑动的起点和终点。
本发明实施方式的电子装置100利用霍尔元件34和磁场产生元件32确定滑动组件20的当前相对位置，在前置相机等功能器件40承载在滑动组件20上时，可以实时地检测滑动组件20的状态，从而确定功能器件40的位置。
可以理解，摄像模组42等功能器件40需要自本体10露出，否则无法正常工作。本发明实施方式的电子装置100通过在滑动组件上承载功能器件40，使得功能器件40在不需要工作时收容在本体10内，在需要工作时随着滑动组件20从本体10露出。如此，无需在显示组件14上开设用以露出摄像模组42等功能器件40的通孔，从而增大屏占比，进而提高用户的体验。
然而，驱动组件和滑动组件等都是有寿命的，如果能够在非必要的情况下，减少对驱动组件以及滑动组件的使用，则会大大提高其寿命，提升用户的使用体验。比如，很多用户喜欢对一些应用进行加密，比如微信等，当直接从微信界面灭屏后，亮屏人脸解锁成功后第一个界面就是应用加密了，这时候人脸识别已经成功，我们会设置延时下降时间，如果在延时时间内应用加密没有去请求人脸识别服务持有相机，滑动组件就会降下，但是紧接着因为微信应用加密需要进行人脸识别，滑动组件又会升起，导致在较短的时间内，滑 动组件多次升降，增加对滑动组件等相关组件的损耗。
为了避免这种损耗，本发明准确识别短时间内多次调用摄像模组的场景，针对短时间内多次调用摄像模组的操作，仅仅释放对摄像头的调用，而延时滑动组件滑入，避免短时间内对摄像模组的多次滑入和滑出控制。
下面具体描述对摄像模组控制方法。
图8是根据本发明一个实施例的摄像模组控制方法的流程图，如图8所示，该方法包括：
步骤101，在接收到人脸识别应用发送的人脸识别请求后，控制驱动组件驱动滑动组件带动摄像模组滑出至第二位置。
人脸识别应用在启用时，会发送针对摄像模组的调用请求，在接收到该请求后，控制驱动组件驱动滑动组件带动摄像模组由第一位置滑出至第二位置，以为该人脸识别应用提供人脸图像采集服务。
需要说明的是，本发明实施例的人脸识别应用除了可以是任意使用人脸加密的应用，包括使用人脸加密的文件应用、微信应用、锁屏等。
步骤102，在获取到人脸识别应用对摄像模组的释放请求后，根据预设的延时策略，向驱动组件发送延时预设时长的延时收回指令，以维持滑动组件在预设时长内处于第二位置。
可以理解，当获取到人脸识别应用对摄像模组的释放请求后，并不立即滑入滑动组件，而是根据预设的延时策略，向驱动组件发送延时预设时长的延时收回指令，以维持滑动组件在预设时长内处于第二位置，也就是说，在本发明的实施例中，为了避免短时间内存在连续的人脸是被应用调用摄像模组，在前一个人脸识别应用释放对摄像模组的调用后，并不立即滑入滑动组件，以避免在滑入后短时间内收到下一个人脸识别应用发送的人脸识别请求，导致滑动组件在短时间内多次滑入滑出导致的硬件损耗。
其中，预设时长根据大量实验数据标定，通常，在预设时长内，还以涵盖顿时间内两个人脸识别应用调用摄像模组的场景，当然，在本实施例中，预设时长还可以通过用户的操作习惯设置，比如，用户的操作习惯为在解锁手机后，先查看当日新闻，再进入人脸加密的解锁应用，则针对该用户对应的电子装置设置的预设时长较长。
在实际执行过程中，申请人发现在针对灭屏的电子装置进行人脸识别解锁过程中，除了人脸识别服务去控制滑动组件外，锁屏应用直接去控制滑动组件的滑入滑出将会提高摄像模组的服务质量，因为亮屏后锁屏应用是提前于人脸识别模块知道的，同理滑动组件滑入时锁屏应用也会提前知道，以便提前于人脸识别服务降下滑动组件或者识别失败控制滑动组件维持升起，因此，当根据人脸识别应用的应用标识，确定人脸识别应用是否是锁屏 应用时，由于锁屏应用相对人脸识别模块可以较早的获知对滑动组件的控制需求，因而，还可以设置锁屏应用控制驱动滑动组件的驱动组件的驱动操作，由此，提高了对滑动组件的控制效率，便于提高滑动组件的快速滑入滑出。
在本发明的一个实施例中，如图9所示，获取到人脸识别应用对摄像模组的释放请求的场景包括两种，第一种为人脸识别成功，此时人脸识别应用释放掉对摄像模组的调用，还有一种是人脸识别一直失败，此时造成人脸识别一直失败的原因可能的是对应的人脸识别应用个卡顿等原因导致，在这种情况下，为了不影响其他人脸识别应用对摄像模组的调用，在检测到人脸识别应用占用摄像模组的时长超过预设时长，比如超过30秒，或者人脸识别失败次数超过预设次数，则强制该人脸识别应用释放对摄像模组的调用。
步骤103，在预设时长内，检测是否获取到人脸识别请求，若没有获取到人脸识别请求，则控制驱动组件在预设时长后驱动滑动组件带动摄像模组滑入至第一位置。
具体地，在预设时长内，检测是否获取到人脸识别请求，若在预设时长内，获取到人脸识别请求，则移除延时收回指令，使得发送人脸识别请求的人脸识别应用可以正常使用摄像模组。
如果在预设时长内，没有获取到人脸识别请求，则表明没有对摄像模组的调用需求，从而控制驱动组件驱动滑动组件带动摄像模组滑入至第一位置，以避免摄像模组滑出时间较长，导致资源浪费，以及增加被碰撞的机会。
当然，在一种可能的实现方式中，可以在系统前台运行的应用为人脸识别应用且电子装置亮屏时，始终保持滑动组件处于第二位置，以尽可能最大化的减小滑动组件的损耗，在本实施例中，继续参照图9，可以在控制驱动组件在预设时长后驱动滑动组件带动摄像模组滑入至第一位置之前，确定当前系统前台运行的应用类型是不是人脸识别应用类型(比如根据前台应用的应用标识与预存的人脸识别应用的应用标识进行比对，根据比对结果来确定当前系统前台运行的应用类型是不是人脸识别应用类型)，或者，电子装置是否灭屏，若在预设时长内，确定当前系统前台运行的应用类型不是人脸识别应用类型，或者，电子装置灭屏，则驱动滑动组件带动所述摄像模组滑入至第一位置，若确定当前系统前台运行的应用类型为人脸识别应用类型，和，电子装置亮屏，则为了随时为相关人脸识别应用提供人脸识别服务，维持滑动组件在预设时长内处于第二位置。
需要说明的是，根据应用场景的不同，上述在预设时长内，检测是否获取到人脸识别请求的方式不同，作为一种可能的实现方式，参照上述实施例，根据是否获取到具体的人脸识别请求来确定，作为另一种可能的实现方式，预先创建记录滑动组件请求的计数器，其中，计数器的初始值为零，在获取到人脸识别请求后，计数器加一处理，当获取到对摄像模组的释放请求后，计数器减一处理，由此，显而易见的是，当计数器的计数值为零时， 表示此时没有人脸识别应用占用摄像模组，当计数器的计数值为一时，表示此时有人脸识别应用占用摄像模组。因而，可以通过在预设时长内，检测是否存在计数器的计数值由零变化为一，检测是否获取到人脸识别请求。
举例而言，如图10所示，预先创建记录滑动组件请求的计数器，该计数器的初始值为0，当接收到锁屏应用对摄像模组的调用请求后，滑动组件接收到滑出指令，此时滑动组件带动摄像模组滑动到第二位置，计数器的计数值加一，当锁屏应用释放对摄像模组的占用后，接收到摄像模组发送的对摄像模组的释放请求，此时滑动组件虽然接收滑入指令，但是根据预设的延时策略，延时滑动组件的滑入，但此时计数器的计数值减一处理变为零，当所述计数器的计数值为零时，在预设时长内(在本实例中，预设时长为400ms)，检测是否获取到人脸识别请求，如果没有获取到人脸识别请求，则在400ms内，检测计数器的计数值为零，不存在由零变为一的情况，因而，控制驱动组件在预设时长后驱动滑动组件带动摄像模组滑入至第一位置。
综上，本发明实施例的摄像模组控制方法，通过滑动组件降低相关组件对屏幕占比的影响，且在降低了滑动组件的损耗，当在短时间内具有对摄像模组的控制请求时，维持摄像模组处于滑出状态，避免相关组件在短时间内进行多次操作，灵活性和实用性较高。
为了实现上述实施例，本发明还提出了一种摄像模组控制装置，摄像模组用于电子装置，电子装置包括本体、检测组件、滑动组件和驱动组件，驱动组件用于控制滑动组件在收容于本体的第一位置和自本体露出的第二位置之间滑动，检测组件包括磁场产生元件和霍尔元件，磁场产生元件和霍尔元件分别固定在滑动组件和本体上，摄像模组与滑动组件硬连接，图11是根据本发明一个实施例的摄像模组控制装置的结构示意图，如图11所示，该装置包括：控制模块10、发送模块20和处理模块30。其中，
