具体实施方式
下面将结合本申请实施例中的附图，对本申请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申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”，一般表示前后关联对象是一种“或”的关系。
下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的视频拍摄方法进行详细地说明。
本申请实施例提供的视频拍摄方法，可以是包括摄像头的电子设备，例如手机、笔记本电脑、一体机或平板电脑等具有通讯功能的终端设备，也可以是在物理机上运行的虚拟机或模拟器模拟的设备，或者，也可以是服务器，例如，云服务器或者服务器集群等具有存储以及计算功能的设备。其中，摄像头组件可以集成在电子设备中，例如，具有拍摄功能的手机、平板电脑等，或者带有摄像头的笔记本电脑；或者，摄像头也可以作为电子设备外接设备，通过有线或无线的通信方式与电子设备建立通信连接，以通过对应的通信方式与电子设备传输拍摄数据等通信数据。
本申请实施例提供的一种可选的视频拍摄方法，可以通过已经配置好切换时间点以及对应的摄像头配置的录像模板(第一录像模板)进行录像，可以在拍摄录像时，按照预设的录像模板进行拍摄视频，以在视频拍摄的过程中，在每次到达切换时间点时，将摄像头的配置切换为预设的配置，进而通过预设的摄像头配置拍摄视频，这样，可以在视频拍摄之前可以将摄像头配置以及切换摄像头配置的时间点设置好，从而在拍摄时自动切换，解决了视频录制时手动切换摄像头配置导致录制画面抖动的问题，方便了用户拍摄视频时的操作，不仅可以使录制画面更稳定，而且避免了在拍摄视频时切换配置可能会导致用户误操作，切换至非用户需求的摄像头配置，使得用户不得不重新拍摄视频的情况。
在一些可选的实施方式中，用户可以在视频拍摄之前，录制好视频拍摄的模板，对切换时间点和切换的摄像头配置进行设置，设置好之后可以进行保存。接着，在拍摄视频时，用户就可以选择已录制的模板拍摄视 频，用户拍摄视频时，摄像头配置就可以在对应的时间点切换，方便了用户的操作。
以下结合图1对本申请实施例提供的视频拍摄方法进行说明，如图1所示，本申请实施例提供的一种可选的视频拍摄方法具体可以包括如下步骤：
步骤101，接收用户的第一输入。
第一输入是用户指示使用第一录像模板拍摄录像的输入。第一输入可以包括用户多个操作输入的组合，如用户可以先输入指示使用第一录像模板的输入，再输入指示拍摄录像的输入。可选的，如果在手机中不存在其它的录像模板，或者用户在设置好第一录像模板之后开始拍摄的情况下，可以默认选择第一录像模板作为录像模板，也即，在诸如上述的一些情况下，第一输入可以只包括指示开始拍摄录像，而拍摄录像时所使用的录像模板则是默认的。第一输入可以是通过用户输入单元接收的，例如，用户输入单元可以包括触摸屏、键盘、鼠标、触控面板等输入组件或外接设备。
例如，以本申请实施例提供的方法由手机执行为例，接收用户的第一输入的一种可选的实现方式可以是，在如图2所示的手机200的***桌面的界面201上，点击“相机”功能图标202，以打开如图3a所示的相机功能界面301。在如图3a所示的相机功能界面301中，用户可以点击“选择录像模板”的功能图标302，以弹出如图3b所示的选择录像模板的菜单弹窗303，在候选的录像模板中，用户可以点击选择“第一录像模板”的选项304。其中，候选录像模板可以包括用户在该手机上预先录制并保存的模板，也可以包括在其它的电子设备上录制并保存的模板，通过本地导入或者网络下载等方式，使其它电子设备上的模板可以作为该手机中的候选录像模板。在用户选中第一录像模板之后，候选录像模板的菜单弹窗303可以消失，接着，用户可以在如图3a所示的相机功能界面301中，点击“录像”的功能图标305，以指示手机基于第一录像模板开始录像。
步骤102，响应于第一输入，基于第一录像模板开始拍摄录像；第一录像模板中包括多个摄像头配置及其对应的切换时间点的组合。
在接收到第一输入之后，可以确定接收到基于第一录像模板拍摄录像的指示，进而，响应于第一输入，可以开始基于第一录像模板开始拍摄录像。
第一录像模板是预先配置好切换摄像头配置时间点的配置模板，包括多个摄像头配置及其对应的切换时间点的组合。摄像头配置是对摄像头的配置。摄像头配置可以包括在多个摄像头中选择拍摄的摄像头的配置，例如，一种可选的手机可以包括“主摄”、“前置”、“潜望”、“广角”等四个摄像头，其中，“前置”可以是在手机的正面(主显示屏所在的面)设置的摄像头，“主摄”、“潜望”、“广角”则是手机的背面设置的摄像头，摄像头配置可以是在四个摄像头中选择一个作为拍摄的摄像头。可选地，摄像头配置还可以包括对摄像头参数进行的配置，例如，一种摄像头参数可以是对摄像头焦距参数的配置，如在预设的长焦模式和短焦模式中选择一个焦距模式，或者，具体设置焦距的范围，以对焦距参数进行设置；或者，摄像头参数也可以包括对摄像头的曝光参数的设置，例如可以设置为强曝光模式或弱曝光模式，以对曝光参数进行设置。
步骤103，在拍摄的过程中，在到达目标切换时间点时，将摄像头配置切换至与目标切换时间点对应的目标摄像头配置，并利用目标摄像头配置继续拍摄视频。
第一录像模板中已经提前设置好多个组合，每个组合包括一个切换时间点，和该切换时间点对应设置的摄像头配置。这样，在拍摄视频时，根据第一录像模板，每到达一个切换时间点，则切换至对应的摄像头配置。
可选地，在拍摄视频的过程中，为了更直观的向用户指示出在第一录像模板中的进度，可以在接收到用户的第一输入之后，响应于第一输入，显示第一录像模板的时间轴。第一录像模板的时间轴是通过时间轴的形式展示出第一录像模板的预设时长，并且，在第一录像模板的时间轴中，标注出每个切换时间点，以及每个切换时间点对应的摄像头配置。在拍摄视频的过程中，可以根据当前拍摄时长，在时间轴中指示出当前拍摄时长在第一录像模板的时间轴中的位置。
图4a是一种可选的拍摄过程中显示第一录像模板时间轴的界面示意 图，在开始录像之后，如图4a所示，可以显示曲线401表示时间轴，曲线401是折线，曲线401在横轴方向上的投影长度用于表示第一录像模板的预设时长，也即，横线用于表示时长，而纵轴方向上的折线用于表示对摄像头进行了切换，每个折线处用于表示切换了一次摄像头，不同摄像头在纵轴方向上的高度是不同的，一个高度对应于一个摄像头。如图4a所示，在视频开始录制的时间点402，选择使用前置摄像头进行拍摄，通过前置摄像头对应的图标403表示具体的摄像头是前置摄像头；在切换时间点403处，曲线401弯折两次，以使得横线的高度切换至主摄像头对应的高度，并通过主摄像头对应的图标405表示摄像头切换至主摄像头；在切换时间点406处，曲线再次弯折两次，以使得横线的高度切换至潜望摄像头对应的高度，并通过潜望摄像头对应的图标407表示摄像头切换至潜望摄像头。在切换时间点408处，曲线再次弯折两次，以使得横线的高度切换至广角摄像头对应的高度，并通过广角摄像头对应的图标409表示摄像头切换至广角摄像头。而在拍摄过程中，第一标识410则用于指示当前拍摄时长在第一录像模板的时间轴中的进度位置。
图4b是另一种可选的拍摄过程中显示第一录像模板时间轴的界面示意图，在开始录像之后，如图4b所示，可以显示进度条421表示时间轴，进度条421被每两个相邻的切换时间点分割出一个时段，得到多个时段，在每个时段的进度条内标记有对应的摄像头配置，具体地，每个时段的摄像头配置是对应时段的首切换时间点对应的摄像头配置。在拍摄时，每到达一个切换时间点之后，摄像头配置会切换至以该切换时间点为起始点的时段的摄像头配置。在拍摄过程中，第一标识422可以跟随拍摄时长的变化，在进度条421的下方向右移动，以指示出当前拍摄时长在进度条421中的进度位置。
以上步骤101～步骤103用于说明基于一个录像模板拍摄视频的过程，在本申请实施例的一些可选的实施方式中，在执行步骤101之前，用户可以录制录像模板。如图5所示为一种可选的实施方式，除步骤101～步骤103之外，在步骤101之前，还包括如下步骤501～步骤502：
步骤501，响应于用户的第二输入，启动第一录像模板的录制。
第二输入是用户指示开始录制第一录像模板的输入。第二输入可以包括用户多个操作输入的组合，如用户可以先输入指示进入录制第一录像模板的功能界面的输入，再输入指示开始录制第一录像模板的输入。第二输入可以是通过用户输入单元接收的，例如，用户输入单元可以包括触摸屏、键盘、鼠标、触控面板等输入组件或外接设备。
例如，以本申请实施例提供的方法由手机执行为例，用户可以在如图2所示的手机***桌面的界面201上，点击“相机”功能图标202，以打开如图3a所示的相机功能界面301。在如图3a所示的相机功能界面301中，用户可以点击“录制录像模板”的功能图标306，以弹出如图6a所示的录制录像模板的功能界面(模板录制页面)601，接着，用户可以点击功能界面601中的录制图标603，开始录制录像模板。一种可选的示例为，在功能界面601中，可以显示有多个候选摄像头配置的图标6021～6024，图标6021～6024用于分别表示手机的四个摄像头，用户可以点击其中一个图标，作为开始录制时默认使用的摄像头，接着，用户可以点击录制图标603开始录制录像模板，从而使得在开始录制之前用户选择的默认摄像头作为录像模板开始时的摄像头。
步骤502，在第一录像模板的录制过程中，响应于用户的第六输入，设置至少一组摄像头配置及其对应的切换时间点。
可选地，在开始录制第一录像模板时，可以开始计时。在第一录像模板录制的过程中，用户可以通过第六输入设置一组摄像头配置及其对应的切换时间点，具体而言，设置一组摄像头配置及其对应的切换时间点包括设置切换时间点，以及设置该切换时间点的摄像头配置。一个切换时间点对应于一个摄像头配置，可选地，一个摄像头配置可以包括对多种摄像头参数设置的配置，例如，对在多个摄像头中选择拍摄使用的摄像头的配置，对摄像头的焦距参数的配置，对摄像头的曝光参数的配置，等等。
例如，一种可选的实施方式为，如图6a所示，在用户点击录制图标603开始录制之后，用户可以在任意时刻点击录制图标603以暂停录制，接着点击设置摄像头配置的图标604或图标605；其中，图标604用于对摄像头的焦距范围进行设置，在点击图标604之后，可以弹出如图6b所 示的滑动条6041，用户可以按住滑动钮6042在滑动条6041上滑动，以选择摄像头的焦距数值；图标605则用于对摄像头的曝光参数进行设置，在点击图标605之后，可以弹出类似于图6b所示的滑动条6041的滑动条，以使用户调节曝光参数的数值，在此不再示出图例。在滑动至一个位置之后，如果超过一定的时长(如2秒钟)不再接收到用户针对滑动钮的操作，则确定用户设置完成，滑动条消失，切换为如图6a所示的功能界面601，接着，用户可以点击录制图标603，以继续开始录制，至此，完成对一个切换时间点及其对应的摄像头配置的设置。在任意时刻，用户都可以暂停录制，对摄像头配置进行设置。最后，用户可以点击结束录制图标606，以结束录制第一录像模板。通过对摄像头焦距范围的配置，可以在拍摄视频时变化焦距，可以实现在拍摄运动物体时对焦到物体移动到的位置，或者产生虚焦的效果等，且无需在拍摄时对手机进行操作，不仅简化了拍摄时的操作，而且也可以防止拍摄画面抖动。
又如，在另一种应用场景中，用户只针对摄像头的选择进行配置，在手机包括多个摄像头的情况下，可以通过切换不同的摄像头在视频中拍摄到不同的视角。那么，用户可以在如图6a所示的功能界面601中点击录制图标603之后，开始计时，如果在任意时刻用户点击了候选摄像头配置的图标6021～6024之一，则将用户点击图标的时刻作为一个切换时间点，将用户点击的图标对应的候选摄像头配置作为该切换时间点对应的摄像头配置。
进一步的，在录制时，可以如图6c所示，绘制一条随着时间的推进延长的横线(沿第一方向)，横线的高度表示当前选择的摄像头，如果用户点击另一个摄像头的图标，则绘制一条竖线(沿第二方向)，表示切换摄像头，竖线的高度绘制到切换的摄像头对应的高度，接着继续绘制横线，以使横线表示时间的推进，竖线表示摄像头的切换，不同的横线高度分别表示对应的摄像头。如图6c所示显示出执行以下操作之后绘制出的曲线：用户在第1.9s点击了主摄即主摄像头的图标6023，摄像头在这个时间点从前摄即前置摄像头切换到主摄，接着，用户又在第3s点击了潜望即潜望摄像头的图标6024，摄像头在这个时间点从主摄切换到潜望。可选的，还可 以在曲线上标识出摄像头配置对应的图标，如图6c所示，在每个转折点处标识出该转折点所在横线所对应的摄像头配置的图标，也即，如果是由横线切换为竖线，则在该转折点处标识出切换之前的摄像头配置的图标，如果是由竖线切换为横线，则在该转折点处标识出切换之后的摄像头配置的图标。
作为一种可选的实施方式，由于屏幕能够显示的区域有限，在录制模板时，随着时间的推进，可以控制已绘制的曲线向左移动，直至从左侧移出屏幕的显示区域，以使屏幕中只呈现最近绘制的部分曲线。最后，在用户点击结束录制图标606之后，结束录制，可以显示如图6d所示的界面示意图，展示用于表征已录制的第一录像模板的完整的折线，用户点击保存图标607之后，确定保存此次录制的录像模板，也可以点击取消图标608以放弃此次录制的录像模板。
在通过上述绘制曲线的可选实施方式录制第一录像模板的情况下，在使用第一录像模板拍摄视频时，可以在界面中显示绘制完毕的曲线来表示第一录像模板的时间轴，并通过第一标识来指示当前拍摄时刻在时间轴中的位置，一种可选的示例为如图4a所示的界面示意图。
作为另一种可选的实施方式，在录制第一录像模板时，还可以是自动设置切换时间点和/或每个切换时间点对应的摄像头配置，进一步地，可以由用户调整自动设置好的切换时间点和/或对应的摄像头配置。举例而言，用户可以为第一录像模板选择音频文件，作为拍摄视频的背景音乐，这样，电子设备可以根据音频文件的声音强度变化，在音频文件的声音强度较高、或者声音强弱变化较大等地方设置切换时间点。进而，由用户设置每个切换时间点需要切换至哪个摄像头配置。
例如，用户可以在如图3a所示的相机功能界面301中，点击“录制录像模板”的功能图标306，然后，进入如图7a所示的界面，显示手机本地的音频文件，用户在点击一个音频文件701以选中该音频文件之后，点击用于指示确定的图标702，则手机将选中的音频文件作为第一录像模板的背景音乐，并且，手机会分析音频文件的声音波形图，声音波形图是纵轴为声音强度、横轴为时间轴的波形图，一种示例的声音波形图如图7b所 示。由于音乐响度的突然增强或减弱这种关键点，通常是用户期望设置切换摄像头配置的时机，因此，手机可以将声音强度变化的幅度超过预设阈值的目标时刻作为切换时间点，接着，可以显示如图7c所示的界面，显示用于表示第一录像模板的录像时长(也即音频文件的时长)的进度条703，其中，进度条被每两个相邻的切换时间点分割为多个时段。在显示出进度条之后，用户可以分别点击每个时段的显示区域，以对该时段内的摄像头配置进行设置，如图7d所示，在设置之后，每个时段的显示区域内可以显示有已设置的摄像头配置的标识。在每个时段都设置完毕之后，用户可以点击确定图标702以指示手机保存(可以是缓存)第一录像模板。可选的，在点击确定图标702之后，还可以显示录制图标704，如果用户点击录制的图标704，则直接使用已确定的第一录像模板开始拍摄视频，并且在拍摄时按照第一录像模板设置的切换时间点切换摄像头配置。在这种情况下，拍摄视频时一种可选的显示界面可以如图4b所示。在拍摄完毕之后，手机会自动为拍摄的视频添加用户所选中的音频文件作为背景音乐。在视频拍摄结束后，视频将会保存在本地中。
本申请实施例提供的视频拍摄方法，通过录像模板预先设置好的切换时间点和摄像头配置，使得在拍摄过程中，自动的在切换时间点切换至对应的摄像头配置，以使得用户可以在拍摄过程中不对摄像头配置进行操作，从而防止了画面抖动，并且可以使用户在录制过程中可以不对摄像头配置进行操作就自动切换摄像头配置，增加了视频拍摄的可玩性和便捷性，提高了用户体验。
需要说明的是，本申请实施例提供的视频拍摄方法，执行主体可以视频拍摄装置，或者该视频拍摄装置中的用于执行加载视频拍摄方法的控制模块。本申请实施例中以视频拍摄装置执行加载视频拍摄方法为例，说明本申请实施例提供的视频拍摄方法。

第一拍摄模块802，用于响应于第一输入，基于第一录像模板开始拍 摄录像；第一录像模板中包括多个摄像头配置及其对应的切换时间点的组合；
