具体实施方式
请参照图式，其中相同的组件符号代表相同的组件，本申请的原理是以实施在一适当的运算环境中来举例说明。以下的说明是基于所例示的本申请具体实施例，其不应被视为限制本申请未在此详述的其它具体实施例。
本申请实施例首先提供一种摄像头控制方法，该摄像头控制方法应用于电子设备。请参照图1，图1为摄像头控制方法所应用的电子设备的一结构示意图。其中，电子设备20可为计算设备诸如膝上型计算机、包含嵌入式计算机的计算机监视器、平板电脑、蜂窝电话、媒体播放器、或其他手持式或便携式电子设备、较小的设备(诸如腕表设备、挂式设备、耳机或听筒设备、被嵌入在眼镜中的设备或者佩戴 在用户的头部上的其他设备，或其他可佩戴式或微型设备)、电视机、不包含嵌入式计算机的计算机显示器、游戏设备、导航设备、嵌入式系统(诸如其中具有显示器的电子设备被安装在信息亭或汽车中的系统)、实现这些设备中的两个或更多个设备的功能的设备、或其他电子设备。在图1的示例性配置中，电子设备20是便携式设备，诸如蜂窝电话、媒体播放器、平板电脑、或者其他便携式计算设备。如果需要，其他配置可用于电子设备20。应当说明的是，图1所示出的结构仅是示例性的。
如图1所示，电子设备20包括壳体诸如壳体200。壳体200可由塑料、玻璃、陶瓷、纤维复合材料、金属(例如，不锈钢、铝等)、其他合适的材料、或这些材料的任意两种或更多种的组合形成。壳体200可使用一体式配置形成，在该一体式配置中，一些或全部壳体200被加工或模制成单一结构，或者可使用多个结构(例如，内框架结构、形成外部外壳表面的一种或多种结构等)形成。
壳体200可以作为电子设备20的载体，可以承载电子设备20的器件。
如图1所示，电子设备20还可以包括电路板诸如电路板400。电路板400可以作为电子设备20的主板，电路板400上可以集成处理器、存储器、摄像头等器件。电子设备20的存储器可以存储电子设备20的各种计算机程序和数据。电子设备20的处理器可以是电子设备20的控制中心，可以利用各种借口和线路连接整个电子设备20的各个部分，通过运行或调用存储在存储器内的计算机程序，以及调用存储在存储器内的数据，执行电子设备20的各种功能和处理数据，诸如处理器可以控制电子设备20的摄像头拍照等。
如图2所示，图2为图1所示电子设备中电路板的结构示意图。电路板400上可以集成多个电子设备20的功能器件，诸如摄像头、传感器等。在一些实施例中，电路板400上可以设置一个或多个安装区诸如安装区440。安装区440可以安装电子设备20的各种功能器件，诸如摄像头。在一些实施例中，电路板400上也可以设置一个或多个收纳空间诸如收纳空间420。收纳空间420可以收纳电子设备20的功能器件，或者说收纳空间420可以避让电子设备20的功能器件，诸如摄像头。
其中，收纳空间420可以为设置在电路板400边缘的缺口，或者说凹槽。收纳空间420也可以为在电路板400厚度方向上贯穿电路板400的通孔，或者说镂空设置。其中，安装区440可以排布电路板400的线路。
可以理解的是，电子设备400上的安装区440和收纳空间420可以相互间隔开设置。需要说明的是，电子设备400上的其中一个安装区440和其中一个收纳空间420可以相邻设置。
请参阅图3，图3为图1所示电子设备的后视图。电子设备20还可以包括摄像头模组40。摄像头模组40可设置在电子设备20的壳体200上，诸如摄像头模组40可以设置在壳体200的后盖位置，摄像头模组40可以作为电子设备20的后置摄像头。需要说明的是，摄像头模组40也可以作为电子设备20的前置摄像头，可以将摄像头模组40设置在电子设备20的显示屏位置。
请参阅图4，图4为图3所示电子设备中摄像头模组的结构示意图。摄像头模组40可包括至少两个摄像头。至少一个摄像头设置在电路板400上，诸如至少一个摄像头可以设置在电路板400的安装区440上。至少一个摄像头可以设置在电路板400上开设的收纳空间420内。
可以理解的是，通常摄像头模组40的多个摄像头中各个摄像头的功能作用不同，各个摄像头的尺 寸也不同。诸如摄像头模组40中有些摄像头的高度较高，有些摄像头的高度较低。本申请实施例可以将高度较高的摄像头设置在电路板400上开设的收纳空间420内，可以将高度较低的摄像头设置在电路板400上的安装区440。相比将所有的摄像头都安装在电路板400上可以减少电路板400和摄像头模组40相互层叠的厚度。而且相比将所有摄像头都安装在电路板400开设的收纳空间420内可以增加电路板400上的线路排布。
需要说明的是，在电子设备功能越来越多，内部器件越来越多的情况下，电路板400的空间越来越有限。本申请不仅可以在整体上不会额外整机电子设备20的厚度，而且还可以增加电路板的尺寸，以排布线路，实现电路板400更多的功能和控制。
示例性的，摄像头模组40可以包括A摄像头42、B摄像头44、C摄像头46和D摄像头48。其中，A摄像头42和D摄像头48至少有一个的高度大于B摄像头44和C摄像头46的高度。比如：A摄像头42的高度均大于B摄像头44和C摄像头46的高度，D摄像头48的高度与B摄像头44或C摄像头46的高度基本相等。再比如：A摄像头42和D摄像头48两者的高度均大于B摄像头44和C摄像头46的高度。其中，B摄像头44和C摄像头46两者的高度大致相等。本申请实施例可以将A摄像头42和D摄像头48设置在电路板400开设的收纳空间420内，可以将B摄像头44和C摄像头46设置在电路板400的安装区46。这样有利于摄像头模组40整体高度的排布，可以更大程度上减少电子设备20的厚度。
本申请提供一种摄像头控制方法，应用于电子设备，所述电子设备包括多个焦距不同的摄像头，所述摄像头控制方法包括：
在处于拍摄预览模式时，侦测前台运行的第一摄像头的对焦距离变化趋势，所述第一摄像头采集的图像被设为预览图像；
根据预设的对焦距离变化趋势和摄像头的对应关系，确定对应所述对焦距离变化趋势的第二摄像头；
在后台启动确定的所述第二摄像头；
当所述第一摄像头的实时对焦距离位于所述第二摄像头对应的对焦距离区间内时，将所述第二摄像头切换至前台运行，并将所述第二摄像头采集的图像设为预览图像。

基于以上电子设备的结构，对本申请实施例提供的摄像头控制方法进行说明，请参照图5，图5为本申请实施例提供的摄像头控制方法的流程示意图。该摄像头控制方法应用于本申请实施例提供的电子设备，该电子设备包括多个焦距不同的摄像头，如图5所示，本申请实施例提供的摄像头控制方法的流程可以如下：
101，在处于拍摄预览模式时，侦测前台运行的第一摄像头的对焦距离变化趋势，第一摄像头采集的图像被设为预览图像。
应当说明的是，在本申请实施例中，电子设备包括多个焦距不同的摄像头，比如两个摄像头、三个摄像头、四个摄像头等。以四个摄像头为例，请参照图4，电子设备包括A摄像头42、B摄像头44、C摄像头46以及D摄像头48，其中，D摄像头48的焦距小于C摄像头46的焦距，C摄像头46的焦距 小于A摄像头42的焦距，A摄像头42的焦距小于B摄像头的焦距。可以理解的是，不同焦距的摄像头所适于拍摄的距离不同。
电子设备可以根据用户的操作指令开启拍摄预览模式，在开启拍摄预览模式时，电子设备启动用户配置或者缺省配置的摄像头至前台运行，从而通过该前台运行的摄像头采集预览图像，并通过显示屏显示前台运行的摄像头所采集的预览图像。此外，电子设备还可以根据用户操作，对前台运行的摄像头的对焦距离进行调整，以对不同距离对象进行拍摄，比如，可以增大对焦距离以拍摄更远距离的对象，可以减小对焦距离以拍摄更近距离的对象。
应当说明的是，本申请实施例中将电子设备前台运行的用于采集预览图像的摄像头的记为第一摄像头，该第一摄像头可以为电子设备包括的多个摄像头中的任一摄像头。
比如，以图4所示的四个摄像头为例，电子设备缺省配置的在开启拍摄预览模式时启动至前台运行的摄像头为A摄像头42。
在拍摄预览模式下，电子设备对前台运行的第一摄像头的对焦距离变化趋势进行侦测，得到侦测结果。
其中，在侦测前台运行的第一摄像头的对焦距离变化趋势时，电子设备可以按照预设时间间隔(该预设时间间隔可由本领域普通技术人员根据实际需要取经验值，比如设置为500耗秒)，采样得到第一摄像头在相邻两个时刻的对焦距离，然后，比较相邻两个时刻的对焦距离的大小关系，若后一时刻的对焦距离大于前一时刻的对焦距离，则可得到第一摄像头的对焦距离变化趋势为变大，若后一时刻的对焦距离小于前一时刻的对焦距离，则可得到第一摄像头的对焦距离变化趋势为变小。
在102中，根据预设的对焦距离变化趋势和摄像头的对应关系，确定对应对焦距离变化趋势的第二摄像头。
如上所述，电子设备包括的多个摄像头分别适用于不同距离场景的拍摄，可以理解的是，当前台运行的第一摄像头的对焦距离变化趋势为变大时，说明用户想要拍摄更远距离的对象，而当前台运行的第一摄像头的对焦距离变化趋势为变小时，说明用户想要拍摄更近距离的对象，基于此，还在电子设备中预先设置有对焦距离变化趋势和摄像头的对应关系。
相应的，电子设备在侦测到前台运行的第一摄像头的对焦距离变化趋势之后，进一步根据预设的对焦距离变化趋势和摄像头的对应关系，确定对应第一摄像头的对焦距离变化趋势的摄像头，记为第二摄像头。
在103中，在后台启动确定的第二摄像头。
电子设备在确定出第二摄像头之后，在后台启动确定的第二摄像头，以待切换至前台运行。应当说明的是，当第二摄像头在后台启动后，其将实时采集图像，但电子设备并不将第二摄像头采集到的图像作为预览图像，而是进行将第一摄像头实时采集的图像作为预览图像。
在104中，当第一摄像头的实时对焦距离位于第二摄像头对应的对焦距离区间内时，将第二摄像头切换至前台运行，并将第二摄像头采集的图像设为预览图像。
应当说明的是，根据电子设备所包括的多个摄像头适于拍摄距离场景的不同，为每一摄像头划分有 对应的对焦距离区间。其中，针对每一摄像头所划分的对焦距离区间不超过其实际所能达到的对焦距离。
比如，以图4所示的四个摄像头为例，D摄像头48对应的对焦距离区间为[a，b)，A摄像头42对应的对焦距离区间为[b，c)，C摄像头46对应的对焦距离区间为[c，d)，B摄像头44对应的对焦距离区间为[d，e]，其中，对焦距离a<b<c<d<e。
本申请实施例中，电子设备在侦测到第一摄像头的实时对焦距离位于第二摄像头对应的对焦距离区间内时，即将第二摄像头切换切换至前台运行，成为新的第一摄像头，同时，将之前的第一摄像头切换至后台运行，并将第二摄像头采集的图像设为预览图像，即通过该新的第一摄像头采集用于预览的预览图像，以通过屏幕显示其所采集到的预览图像。
比如，以图4所示的四个摄像头为例，缺省启动的第一摄像头为A摄像头42，若确定的第二摄像头为B摄像头44，则在将B摄像头44切换至前台运行的同时，将A摄像头42切换至后台运行，在完成切换后，B摄像头44即成为新的第一摄像头。
由上可知，本申请实施例中，电子设备包括多个焦距不同的摄像头，通过在处于拍摄预览模式时，侦测前台运行的第一摄像头的对焦距离变化趋势，并根据预设的对焦距离变化趋势和摄像头的对应关系，确定对应对焦距离变化趋势的第二摄像头，然后在后台启动确定的第二摄像头，当第一摄像头的实时对焦距离位于第二摄像头对应的对焦距离区间内时，将第二摄像头切换至前台运行，并将第二摄像头采集的图像设为预览图像。由此，通过提前启动需要切换的摄像头，从而无需在切换时实时启动需要切换的摄像头，能够节省切换时的等待时间，从而避免了预览图像的卡顿。
在一实施例中，“当第一摄像头的实时对焦距离位于第二摄像头对应的对焦距离区间内时，将第二摄像头切换至前台运行，并将第二摄像头采集的图像设为预览图像”，包括：
当第一摄像头的实时对焦距离位于第二摄像头对应的对焦距离区间内，且第二摄像头采集的图像与第一摄像头与采集的预览图像的内容重叠时，将第二摄像头切换至前台运行，并将第二摄像头采集的图像设为预览图像。
其中，电子设备并不在第一摄像头的实时对焦距离位于第二摄像头对应的对焦距离区间内时立即将第二摄像头切换至前台运行，而是先判断第一摄像头和第二摄像头采集的图像的内容是否重叠，若第一摄像头与第二摄像头采集的图像内容重叠，在将第二摄像头切换至前台运行，成为新的第一摄像头，从而通过该新的第一摄像头采集用于预览的预览图像。
由于本申请实施例中切换摄像头时不会存在预览图像内容的跳变，能够实现摄像头的无痕切换。
在一实施例中，“根据预设的对焦距离变化趋势和摄像头的对应关系，确定对应对焦距离变化趋势的第二摄像头”，包括：
当对焦距离变化趋势为预设时长内持续变大时，将多个摄像头中焦距大于第一摄像头的摄像头确定为第二摄像头。
本申请实施例中，预设的对焦距离变化趋势和摄像头的对象关系包括：
对焦距离变化趋势为预设时长内持续变大时，对应的摄像头为焦距大于第一摄像头的摄像头。
其中，以预设时长为至少两个预设时间间隔为约束，预设时长的取值可由本领域普通技术人员根据 实际需要取经验值，比如，当预设时间间隔被配置为500毫秒时，可以将预设时长配置为1秒。
相应的，电子设备在根据对焦距离变化趋势和摄像头的对应关系，确定对应对焦距离变化趋势的第二摄像头时，首先获取到第一摄像头在预设时长内的对焦距离变化趋势。比如，用于采用对焦距离变化趋势的预设时间间隔被配置为500毫秒，预设时长被配置为1秒，电子设备可以获取到距离当前时刻最近的1秒内所采样得到的两个对焦距离变化趋势，若获取到的两个对焦距离变化趋势均为变大，则可以判定对焦距离变化趋势在预设时长内持续变大。
当判定第一摄像头的对焦距离变化趋势在预设时长内持续变大时，电子设备即将多个摄像头中焦距大于第一摄像头的摄像头确定为第二摄像头。其中，若焦距大于第一摄像头的摄像头不唯一，也即是焦距大于第一摄像头的摄像头为多个时，电子设备将焦距大于第一摄像头的多个摄像头中焦距最小的摄像头确定为第二摄像头，也即是将其中焦距与第一摄像头最接近的摄像头确定为第二摄像头。
比如，以图4所示的4个摄像头为例，第一摄像头为焦距最小的D摄像头48，此时焦距大于第一摄像头的摄像头不唯一，包括A摄像头42、B摄像头44以及C摄像头46，此时电子设备将其中焦距最小的C摄像头46确定为第二摄像头。
在一实施例中，在将第二摄像头切换至前台运行之后，还包括：
若后台还启动有焦距小于第一摄像头的第三摄像头，则关闭第三摄像头。
本申请实施例中，在将电子设备所包括的多个摄像头中焦距大于第一摄像头的摄像头确定为第二摄像头，并将该第二摄像头切换至前台运行后，识别后台是否还启动有焦距小于之前的第一摄像头的摄像头，记为第三摄像头。
若识别到后台还启动有第三摄像头，则电子设备关闭该第三摄像头，以节省电量消耗。
在一实施例中，“根据预设的对焦距离变化趋势和摄像头的对应关系，确定对应对焦距离变化趋势的第二摄像头”，包括：
当对焦距离变化趋势为预设时长内持续变小时，将多个摄像头中焦距小于第一摄像头的摄像头确定为第二摄像头。
本申请实施例中，预设的对焦距离变化趋势和摄像头的对象关系还包括：
对焦距离变化趋势为预设时长内持续变小时，对应的摄像头为焦距小于第一摄像头的摄像头。
其中，以预设时长为至少两个预设时间间隔为约束，预设时长的取值可由本领域普通技术人员根据实际需要取经验值，比如，当预设时间间隔被配置为500毫秒时，可以将预设时长配置为1秒。
相应的，电子设备在根据对焦距离变化趋势和摄像头的对应关系，确定对应对焦距离变化趋势的第二摄像头时，首先获取到第一摄像头在预设时长内的对焦距离变化趋势。比如，用于采用对焦距离变化趋势的预设时间间隔被配置为500毫秒，预设时长被配置为1秒，电子设备可以获取到距离当前时刻最近的1秒内所采样得到的两个对焦距离变化趋势，若获取到的两个对焦距离变化趋势均为变小，则可以判定对焦距离变化趋势在预设时长内持续变小。
当判定第一摄像头的对焦距离变化趋势在预设时长内持续变小时，电子设备即将多个摄像头中焦距小于第一摄像头的摄像头确定为第二摄像头。其中，若焦距小于第一摄像头的摄像头不唯一，也即是焦 距小于第一摄像头的摄像头为多个时，电子设备将焦距小于第一摄像头的多个摄像头中焦距最大的摄像头确定为第二摄像头，也即是将其中焦距与第一摄像头最接近的摄像头确定为第二摄像头。
比如，以图4所示的4个摄像头为例，第一摄像头为焦距最大的B摄像头44，此时焦距小于第一摄像头的摄像头不唯一，包括A摄像头42、C摄像头46以及D摄像头48，此时电子设备将其中焦距最大的A摄像头42确定为第二摄像头。
在一实施例中，在将第二摄像头切换至前台运行之后，还包括：
若后台还启动有焦距大于第一摄像头的第四摄像头，则关闭第四摄像头。
本申请实施例中，在将电子设备所包括的多个摄像头中焦距小于第一摄像头的摄像头确定为第二摄像头，并将该第二摄像头切换至前台运行后，识别后台是否还启动有焦距大于之前的第一摄像头的摄像头，记为第四摄像头。
若识别到后台还启动有第四摄像头，则电子设备关闭该第四摄像头，以节省电量消耗。
在一实施例中，在“确定对应对焦距离变化趋势的第二摄像头”之后，还包括：
当第一摄像头的实时对焦距离位于第二摄像头对应的对焦距离区间内，且第二摄像头未在后台启动时，则直接启动第二摄像头至前台运行。
需要说明的是，当用户对第一摄像头的对焦距离的调整过快，或者直接将对焦距离调整至第二摄像头对应的对焦距离区间内时，将导致电子设备无法及时在后台启动确定的第二摄像头。针对于这种第一摄像头的实时对焦距离位于第二摄像头对应的对焦距离区间内，且第二摄像头未在后台启动的情况，电子设备直接启动第二摄像头至前台运行。
在一实施例中，本申请实施例提供的摄像头控制方法还包括：
在启动第二摄像头期间，对第一摄像头采集的预览图像进行模糊处理。
应当说明的是，启动摄像头需要花费一定时间，本申请实施例中为了降低启动第二摄像头所带来的卡顿感，在启动第二摄像头期间，还对第一摄像头采集的预览图像进行模糊处理。
其中，对于采用何种方式对第一摄像头采集的预览图像进行模糊处理，本申请实施例中不做具体限制，可由本领域普通技术人员根据实际需要选取模糊处理方式，比如，本申请实施例中，电子设备对第一摄像头采集的预览图像进行高斯模糊处理，使得摄像头的切过程更为平滑。
