Description

一种视频拍摄方法及电子设备
本申请要求于2021年6月16日提交国家知识产权局、申请号为202110676709.3、发明名称为“一种基于故事线模式的用户视频创作方法及电子设备”的中国专利申请的优先权，以及于2021年10月9日提交国家知识产权局、申请号为202111178141.9、发明名称为“一种视频拍摄方法及电子设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及终端技术领域，尤其涉及一种视频拍摄方法及电子设备。
背景技术
目前，手机等电子设备中，不仅可以提供图片拍摄功能，还能提供视频拍摄功能。电子设备采用该视频拍摄功能，可以启动一个摄像头来录制视频。
然而，在多人聚会、亲子互动等具有多个拍摄对象的场景中，若采用上述视频拍摄功能，极有可能出现多个拍摄对象无法同时同框的情况。或者，在演唱会等活动现场中，具有同时拍摄远景和近景的需求，若采用上述视频拍摄功能，也可能无法同时满足用户的多种拍摄需求。
由此可见，亟需一种视频拍摄方案，以灵活适配于各种需要拍摄视频的场景。在此基础上，更缺少一种在各种拍摄场景中，可以灵活设置美颜效果的方案。
发明内容
本申请实施例提供一种视频拍摄方法及电子设备，在切换为采用两个摄像头采集图像的情况下，智能设置美颜效果，以自动关闭后置摄像头的美颜效果。
为达到上述目的，本申请的实施例采用如下技术方案：
第一方面，本申请实施例提供一种视频拍摄方法，该方法可以应用于手机、平板等支持拍摄视频的电子设备。其中，电子设备显示第一界面，第一界面是电子设备录像的取景界面，第一界面中包括第一预览图像，第一预览图像是对第一摄像头采集的第一图像添加第一美颜效果后得到的。第一摄像头是前置摄像头或者后置摄像头。也就是说，在切换前，电子设备为第一摄像头采集的图像添加了第一美颜效果。应注意，该第一美颜效果可以是通过取景界面中的美颜控件(即第一控件)设置的，也可以在采用本申请方案后，自动设置的。而后，电子设备接收用户对第一界面的第一操作，第一操作用于触发电子设备切换使用第二摄像头和第三摄像头采集图像。也就是说，切换后的拍摄模式(即多镜子模式)是采用两个摄像头采集图像的模式。例如，前后双镜模式、后后双镜模式或者画中画模式。在采用两个摄像头采集图像的模式中，通常不会使用后置摄像头来采集人像，因此不需要美颜效果。基于此，在本申请实施例中，电子设备响应于第一操作，显示第二界面，第二界面是电子设备录像的取景界面，第二界面中包括第二预览图像和第三预览图像，第二预览图像是处理第二摄像头采集的第二图像得到的，第三预览图像是处理第三摄像头采集的第二图像得到的。其中，第二预览图像和第三预览图像中对应后置摄像头的预览图像未添加美颜效果。也就是说，在切换后，电子设备不为两个摄像头中的后置摄像头采集的图像 添加美颜效果。
综上所述，采用本实施例的方法，在切换前，电子设备为第一摄像头采集的图像添加了第一美颜效果，而在切换为使用两个摄像头采集图像后，则关闭后置摄像头的美颜效果。从而可以随着拍摄模式的切换，智能的设置美颜效果，提高美颜设置的智能性和合理性。
应注意，在本实施例中，第一摄像头可能与第二摄像头或者第三摄像头相同，例如，第一摄像头是后置主摄像头，第二摄像头是后置主摄像头，第三摄像头是前置摄像头。或者，第一摄像头可能与第二摄像头和第三摄像头都不同，例如，第一摄像头是前置摄像头，第二摄像头是后置广角摄像头，第三摄像头是后置长焦摄像头。本申请实施例对此不作具体限定。
在第一方面的另一种可能的设计方式中，第一界面和第二界面是电子设备录像前的取景界面，或者，第一界面和第二界面是电子设备正在录像的取景界面。
也就是说，采用本实施例的方法，电子设备可以在录像前或者正在录像的过程中，随着拍摄模式的切换，智能的设置美颜效果。其中，通常仅在录像前的取景界面中，提供美颜控件供用户选择美颜效果，而正在录像的取景界面中通常没有。可见，采用本实施例的方法，可以弥补正在录像的过程中，用户不能选择美颜效果的不足，实现自动设置美颜效果。
在第一方面的另一种可能的设计方式中，第一界面全屏显示第一预览图像。
也就是说，采用本实施例的方法，电子设备在从采用单个摄像头采集图像的模式，如单前置模式或者单后置模式，切换到采用两个摄像头采集图像的模式后，可以自动关闭后置摄像头的美颜效果。
在第一方面的另一种可能的设计方式中，第一摄像头是前置摄像头，第二摄像头是前置摄像头，第三摄像头是后置摄像头，第二预览图像是对第二图像添加第一美颜效果后得到的，第三预览图像未添加美颜效果。
也就是说，采用本实施例的方法，电子设备在从采用一个前置摄像头采集图像的模式(如单前置模式)，切换为采用一个前置摄像头和一个后置摄像头采集图像的模式(如前后双镜模式、画中画模式)后，切换后的前置摄像头仍沿用切换前的前置摄像头第一美颜效果，而切换后的后置摄像头则关闭美颜效果。从而可以在从采用一个前置摄像头采集图像的模式，切换到采用一个前置摄像头和一个后置摄像头采集图像的模式后，仅为前置摄像头添加美颜效果。
在第一方面的另一种可能的设计方式中，第一摄像头是后置摄像头，第二摄像头是前置摄像头，第三摄像头是后置摄像头，第二预览图像和第三预览图像均未添加美颜效果。
也就是说，采用本实施例的方法，电子设备在从采用一个后置摄像头采集图像的模式(如单后置模式)，切换为采用一个前置摄像头和一个后置摄像头采集图像的模式(如前后双镜模式、画中画模式)后，切换后的前置摄像头不继续沿用第一美颜效果。同时，关闭切换后的后置摄像头的美颜效果。从而可以在从采用一个后置摄像头采集图像的模式切换为采用一个前置摄像头和一个后置摄像头采集图像的模式后，同时关闭前置摄像头和后置摄像头的美颜效果。其中，关闭前置摄像头的美颜，可以避免切换前后置摄像头的美颜效果，不匹配切换后前置摄像头采集的图像。以及，关闭后置摄像头的美颜效果，可以避免在采用一个前置摄像头和一个后置摄像头采集图像的模式下，开启后置摄像头的美颜效 果。最终可以提升美颜设置的合理性。
在第一方面的另一种可能的设计方式中，第一界面和第二界面是电子设备录像前的取景界面。第一界面包括第一控件，第一界面中的第一控件用于触发电子设备设置第一图像的美颜效果。第二界面包括第一控件，第二界面中的第一控件用于触发电子设备设置第二图像的美颜效果。
也就是说，采用本实施例的方法，在录像前，电子设备可以在采用单个摄像头采集图像的模式的取景界面中提供美颜控件，以供触发电子设备设置该单个摄像头采集的图像的美颜效果。在录像前，电子设备可以在采用一个前置摄像头和一个后置摄像头采集图像的模式的取景界面中提供美颜控件，以供触发电子设备设置其中前置摄像头采集的图像的美颜效果。
在第一方面的另一种可能的设计方式中，第二摄像头是后置摄像头，第三摄像头是后置摄像头，第二预览图像和第三预览图像均未添加美颜效果。
也就是说，采用本实施例的方法，电子设备在从采用一个摄像头采集图像的模式，如单前置模式或者单后置模式，切换为采用两个后置摄像头采集图像的模式，如后后双镜模式后，则两个后置摄像头采集的图像均不添加美颜效果。
在第一方面的另一种可能的设计方式中，第一界面和第二界面是电子设备录像前的取景界面。第一界面包括第一控件，第二界面不包括第一控件；第一控件用于触发电子设备设置美颜效果。
也就是说，采用本实施例的方法，由于采用两个后置摄像头采集图像的模式中，两个后置摄像头都是不支持的美颜的，本实施例中，在录像前，采用两个后置摄像头采集图像的模式的取景界面中，电子设备不提供美颜控件。从而可以适配于两个后置摄像头不支持美颜的情况。
在第一方面的另一种可能的设计方式中，在电子设备显示第二界面之后，上述方法还包括：电子设备接收用户对第二界面的第二操作，第二操作用于触发电子设备切换使用第四摄像头采集图像。电子设备响应于第二操作，显示第三界面，第三界面中全屏显示第四预览图像，第四预览图像是对第四摄像头采集的第四图像添加第一美颜效果后得到的。
也就是说，采用本实施例的方法，在从采用单个摄像头采集图像的模式切换为采用两个摄像头采集图像的模式后，再次从采用两个摄像头采集图像的模式切回采用单个摄像头采集图像的模式，则可以恢复最初单个摄像头的美颜效果。从而可以在切回采用单个摄像头采集图像的模式后，快速恢复美颜效果。
应注意，第四摄像头可以与第一摄像头相同，例如，第一摄像头和第四摄像头都是后置主摄像头。或者，第四摄像头可以与第一摄像头不同，例如，第一摄像头是前置摄像头，第四摄像头是后置主摄像头。
在第一方面的另一种可能的设计方式中，第一摄像头是前置摄像头，第二摄像头和第三摄像头均是后置摄像头。第一界面中还包括第五预览图像，第五预览图像是处理第五摄像头采集的第五图像得到的，第五摄像头是后置摄像头，第五预览图像未添加美颜效果。
也就是说，采用本实施例的方法，电子设备在从采用一个前置摄像头和一个后置摄像头采集图像的模式，如前后双镜模式、画中画模式，切换为采用两个后置摄像头采集图像的模式，如后后双镜模式后，则两个后置摄像头采集的图像均不添加美颜效果。
应注意，与第一摄像头类似，第五摄像头可以与第二摄像头或者第三摄像头相同，或者，第五摄像头
在第一方面的另一种可能的设计方式中，第一界面和第二界面是电子设备录像前的取景界面。第一界面中包括第一控件，第二界面中不包括第一控件。第一控件用于触发电子设备设置美颜效果。
也就是说，采用本实施例的方法，由于采用两个后置摄像头采集图像的模式中，两个后置摄像头都是不支持的美颜的，本实施例中，在录像前，采用两个后置摄像头采集图像的模式的取景界面中，电子设备不提供美颜控件。从而可以适配于两个后置摄像头不支持美颜的情况。
在第一方面的另一种可能的设计方式中，在电子设备显示第二界面之后，上述方法还包括：电子设备接收用户对第二界面的第三操作，第三操作用于触发电子设备切换使用第六摄像头和第七摄像头采集图像。第六摄像头是前置摄像头，第七摄像头是后置摄像头。电子设备响应于第三操作，显示第四界面，第四界面中包括第六预览图像和第七预览图像，第六预览图像是对第六摄像头采集的第六图像添加第一美颜效果得到的，第七预览图像是处理第七摄像头采集的第七图像得到的，第七预览图像未添加美颜效果。
也就是说，采用本实施例的方法，在从采用一个前置摄像头和一个后置摄像头采集图像的模式切换为采用两个后置摄像头采集图像的模式后，再次切回采用一个前置摄像头和一个后置摄像头采集图像的模式，则可以恢复最初采用一个前置摄像头和一个后置摄像头采集图像时的美颜效果。从而可以在切回采用一个前置摄像头和一个后置摄像头采集图像的模式后，快速恢复美颜效果。
应注意，第六摄像头可以与第一摄像头或者第五摄像头相同，或者，第六摄像头可以与第一摄像头和第五摄像头都不同。第七摄像头可以与第一摄像头或者第五摄像头相同，或者，第七摄像头可以与第一摄像头和第五摄像头都不同。

也就是说，采用本实施例的方法，可以在不为后置摄像头自动设置美颜效果的情况下，显示不设置美颜的原因的提示消息。从而可以提升人机交互的体验。
第二方面，本申请实施例提供一种视频拍摄方法，该方法可以应用于手机、平板等支持拍摄视频的电子设备。其中，电子设备显示第一界面，第一界面是电子设备录像的取景界面，第一界面中包括全屏显示的第一预览图像，第一预览图像是对第一摄像头采集的第一图像添加第一美颜效果后得到的。第一摄像头是后置摄像头。即，第一界面是以单后置模式录像的取景界面。并且，第一界面中还包括第一控件，该第一控件可以是模式图标或者是面板展示控件。第一控件用于触发电子设备切换录制模式，录制模式包括：采用单个摄像头采集图像并以全屏显示的模式，如单前置模式或者单后置模式；采用一个前置摄像头和一个后置摄像头采集图像，并以分屏显示的模式，如前后双镜模式；和，采用一个前置摄像头和一个后置摄像头采集图像，并以画中画显示的模式，如画中画模式。电子设备接收用户对第一界面中第一控件的点击操作。电子设备响应于点击操作，在第一界面中显示多个选项，多个选项与多种录制模式一一对应。即，提供录制模式供用户选择。电子设 备接收用户对第一选项的选择操作，第一选项是多个选项中的一个，第一选项对应采用一个前置摄像头和一个后置摄像头采集图像，并以分屏显示的模式；或者，第一选项对应采用一个前置摄像头和一个后置摄像头采集图像，并以画中画显示的模式。电子设备响应于选择操作，显示第二界面，第二界面是电子设备录像的取景界面，第二界面中包括第二预览图像和第三预览图像，第二预览图像是对第二摄像头采集的第二图像处理、且未添加美颜效果后得到的，第三预览图像是对第三摄像头采集的第三图像处理、且未添加美颜效果后得到的。
综上所述，采用本申请实施例的方法，在采用单个后置摄像头采集图像，并全屏显示的模式录像的情况下，若为后置摄像头采集的图像添加有第一美颜效果，则在切换为采用一个前置摄像头和一个后置摄像头采集图像后，如切换为前后双镜模式或者画中画模式后，一方面自动取消掉采用两个摄像头采集图像的场景中，后置摄像头的美颜效果；另一方面为了避免将切换前单个后置摄像头的美颜效果，应用到切换后两个摄像头中的前置摄像头采集的图像上，而自动取消掉前置摄像头的美颜效果。即，电子设备不为切换后的前置摄像头和后置摄像头采集的图像添加美颜效果。从而可以自动提升美颜效果设置的合理性。

下文实施例中的视频拍摄方法，可以在具有上述硬件结构的手机100中实现。
本申请实施例提供的视频拍摄方法，可以应用于手机100中各种需要拍摄视频的场景中，例如，婚礼现场、朋友聚会、旅游等场景。并且，近些年来，随着视频平台的发展，出现了各种新型的视频形式，其中一种典型的形式是视频日志(video log，vlog)，vlog是以影像代替文字或相片，来承载日志的内容的形式。在拍摄vlog的过程中，通常需要拍摄多个对象，例如，拍摄用户自身和用户所在环境。或者，需要以不同的视觉来拍摄同一对象，例如，以近景和远景拍摄同一舞台现场。
然而，受限于常规技术中视频拍摄功能的限制，通常难以满足上述新型的视频形式中的需求。
基于此，本申请实施例提供了一种视频拍摄方法，该视频拍摄方法基于一种新的视频拍摄功能来实现。其中，该视频拍摄功能也可以称为多镜录像模式，与光圈、夜景、人像、拍照、录像等多种常见的拍摄模式构成相机功能的多种拍摄模式。并且，采用多镜录像模式，手机100可同时开启至少两个摄像头来采集预览图像并在取景界面中同时显示该至少两个摄像头采集的预览图像。
示例性的，图2A中的(a)示出的相机应用的取景界面201a中包括子菜单202a，该子菜单202a中不仅包括光圈、夜景、人像、拍照、录像等多种常见的拍摄模式，还包括多镜录像模式。而后，用户选择该多镜录像模式，则可触发手机100开启多镜录像。例如，手机响应于用户对该多镜录像模式的选择操作，可显示图2A中的(b)示出的取景界面203。该取景界面203a中包括摄像头a采集的预览图像204a和摄像头b采集的预览图像205a。即，有两个摄像头在同时采集预览图像。
应注意，图2A中的(b)示出的取景界面203a中仅包括两个摄像头采集的预览图像。 但是实际实施时，多镜录像模式的取景界面中还可以包括三个摄像头、四个摄像头……采集的预览图像，本申请实施例并不以图2A中的(b)示出的摄像头的数量为限。在下文实施例中，将主要以两个摄像头为例来说明本申请方案。
应理解，在采用摄像头a和摄像头b，即两个摄像头，同时采集预览图像的场景中，该摄像头a和摄像头b可以是手机100的多个摄像头中任两个摄像头的组合。例如，图2A中的(b)示出的取景界面203a中，摄像头a可以是后置主摄像头，摄像头b可以是前置摄像头。又如，图2B中的(a)示出的取景界面201b中，包括后置长焦摄像头采集的预览图像202b和后置广角摄像头采集的预览图像203b。即，摄像头a可以是后置长焦摄像头，摄像头b可以是后置广角摄像头。
应注意，图2A中的(b)示出的取景界面203a中预览图像204a和预览图像205a以分屏布局来显示。实际实施时，在多镜录像模式的取景界面中，两个摄像头采集的预览图像还可以以画中画布局来显示。示例性的，手机还可以显示图2B中的(b)示出的取景界面204b，该取景界面204b中包括摄像头a采集的预览图像205b和摄像头b采集的预览图像206b。其中，预览图像205b显示在大窗(即全屏窗口)205B中，预览图像206b显示在小窗206B中，并且，小窗206B在大窗205B内。即，预览图像205b和预览图像206b以画中画布局显示。
另外，在一些实施例中，在多镜录像模式中，手机100可以响应于用户的操作从两个摄像头切换到单个摄像头来取景(具体的实现方式可参见下文中实施例一的说明)。也就是说，多镜录像模式中也可以提供单个摄像头采集预览图像的功能。
示例性的，在多镜录像模式中，手机100可以显示图2C中的(a)示出的取景界面201c。该取景界面201c中包括单个摄像头(如前置摄像头)采集的预览图像202c。或者，手机可以显示图2C中的(b)示出的取景界面203c。该取景界面203c中包括单个摄像头(如后置主摄像头)采集的预览图像204c。
在多镜录像模式的取景界面中，除包括摄像头采集的预览图像外，通常还包括以下元素(如控件、图标)中的一个或多个：
图库资源控件：图库资源控件用于触发手机100展示已拍摄的图片或者视频。例如，图库资源控件是图2A中的(b)示出的取景界面203a中的控件210。
录制控件：录制控件用于触发手机100开始录制视频。例如，录制控件是图2A中的(b)示出的取景界面203a中的控件211。
前后摄像头切换控件：前后置摄像头控件用于触发手机100切换前置摄像头和后置摄像头。例如，前后摄像头切换控件是图2A中的(b)示出的取景界面203a中的控件212。关于前后置摄像头切换的具体内容可参见下文中实施例一的说明，此处暂不做详细说明。
拍摄模式切换控件：拍摄模式切换控件用于触发手机100切换拍摄模式。例如，图2A中的(b)示出的取景界面203a中包括子菜单202a，子菜单202a中的“拍照”是拍照模式的切换控件，“录像”是录像模式的切换控件，“多镜录像”是多镜录像模式的切换控件。
美颜控件：美颜控件用于触发手机100调节美颜级别。例如，美颜控件是图2A中的(b)示出的取景界面203a中的控件213。关于美颜调节的具体内容可参见下文中实施例二的说明，此处暂不做详细说明。
微电影控件：微电影控件用于触发手机100拍摄微电影。例如，微电影控件是图2A 中的(b)示出的取景界面203a中的控件214。关于微电影拍摄的具体内容化可参见下文中关于实施例六的说明，此处暂不做详细说明。
模式图标：模式图标用于指示手机100当前采用的多镜子模式，即，当前采集预览图像的摄像头，以及预览图像的布局。例如，模式图标是图2A中的(b)示出的取景界面203a中的图标215。该图标215由空白矩形和带有笑脸的矩形构成，空白矩形表示后置摄像头，带有笑脸的矩形表示前置摄像头。并且，空白矩形和带有笑脸的矩形上下排列，表示预览图像以上下布局显示。
应注意，在每种多镜子模式下，手机100可以特定摄像头采集预览图像，并将预览图像以特定布局显示。其中，特定摄像头可以是手机100中的任一个摄像头，或者是手机100中的任意两个摄像头的组合。特定布局包括分屏布局、画中画布局和/或全屏布局。
在下文实施例中，为方便说明，主要以多镜子模式包括：采用一个前置摄像头和一个后置摄像头采集预览图像，并以分屏布局显示的模式(简称为前后双镜模式，如图2A中的(b)示出的取景界面203a对应的多镜子模式)；采用两个后置摄像头采集预览图像，并以分屏布局显示的模式(简称为后后双镜模式，如图2B中的(a)示出的取景界面201b对应的多镜子模式)；采用一个前置摄像头和一个后置摄像头采集预览图像，并以画中画布局显示的模式(简称为画中画模式，如图2B中的(b)示出的取景界面204b对应的多镜子模式)；以及，采用一个前置摄像头或者一个后置摄像头采集预览图像，并以全屏布局显示的模式(若采用前置摄像头，则简称为单前置模式，如图2C中的(a)示出的取景界面201c对应的多镜子模式；若采用后置摄像头，则简称为单后置模式，如图2C中的(b)示出的取景界面203c对应的多镜子模式)。
通常情况下，手机100响应于用户对多镜录像模式的选择操作，则默认进入前后双镜模式的取景界面。也就是说，多镜录像模式中，默认的多镜子模式是前后双镜模式。而其它多镜子模式则是直接或者间接从前后双镜模式切换而得到的。
闪光灯图标：闪光灯图标用于触发手机100设置拍摄时的闪光灯参数。例如，闪光灯图标是图2A中的(b)示出的取景界面203a中的图标216。
滤镜图标：滤镜图标用于触发手机100添加拍摄时的滤镜。例如，滤镜图标是图2A中的(b)示出的取景界面203a中的图标217。
设置图标：设置图标218用于触发手机100设置相机参数。例如，设置图标是图2A中的(b)示出的取景界面203a中的图标218。
变焦控件：变焦控件用于触发手机100调节变焦倍率，从而在多个后置摄像头之间切换。例如，变焦控件是图2A中的(b)示出的取景界面203a中的变焦条219，手机100响应于用户对该变焦条219的滑动操作，可切换到相应的后置摄像头来采集预览图像。关于通过变焦条切换后置摄像头的具体内容可参加下文中关于实施例一的说明，此处暂不做详细说明。
关于多镜录像模式，前文主要以录像前的取景取景界面来示意说明。应理解，在多镜录像模式中，录制中开启的摄像头及其数量、预览图像的布局等，基本与录像前类似。
示例性的，在采用两个摄像头取景的场景中。在录像前，手机100可以显示图2A中的(b)示出的录像前的取景界面203a，在录制中，手机100则可以显示图2D中的(a)示出的取景界面201d。该取景界面201d中包括摄像头a(如后置主摄像头)采集的预览图 像202d和摄像头b(如前置摄像头)采集的预览图像203d。其中，预览图像202d和预览图像203d以分屏布局显示。
或者，在录像前，手机100可以显示图2B中的(a)示出的取景界面201b，在录制中，手机100则可以显示图2D中的(b)示出的取景界面204d。该取景界面204d中包括摄像头a(如后置长焦摄像头)采集的预览图像205d和摄像头b(如后置广角摄像头)采集的预览图像206d。其中，预览图像205d和预览图像206d以分屏布局显示。
或者，在录像前，手机100可以显示图2B中的(b)示出的录像前的取景界面204b，在录制中，手机100则可以显示图2D中的(c)示出的取景界面207d。该取景界面207d中包括摄像头a(如后置主摄像头)采集的预览图像208d和摄像头b(如前置摄像头)采集的预览图像209d。预览图像208d显示在大窗(即全屏窗口)208D中，预览图像209d显示在小窗209D中。其中，大窗208D中包括小窗209D。即，预览图像208d和预览图像209d以画中画布局显示。
又示例性的，在采用单个摄像头取景的场景中。在录像前，手机100可以显示图2C中的(a)示出的取景界面201c，在录制中，手机100则可以显示图2E中的(a)示出的取景界面201e。该取景界面201e中包括单个摄像头(如前置摄像头)采集的预览图像202e。
或者，在录像前，手机100可以显示图2C中的(b)示出的取景界面203c，在录制中，手机100则可以显示图2E中的(b)示出的取景界面203e。该取景界面203e中包括单个摄像头(如后置主摄像头)采集的预览图像204e。
应注意，在多镜录像模式中，录制中的取景界面中的元素和录像前的取景界面中的元素会有所不用。通常情况下，在录制中的取景界面中，还可以包括以下元素中的一个或多个：
拍照控件：拍照控件用于触发手机100在拍摄视频过程中截取视频帧。例如，拍照控件是图2D中的(a)示出的取景界面201d中的控件220。
结束录制控件：结束录制控件用于触发手机100结束视频录制。例如，结束录制控件是图2D中的(a)示出的取景界面201d中的控件221。
暂停录制控件：暂停录制控件用于触发手机100暂停视频录制。例如，暂停录制控件是图2D中的(a)示出的取景界面201d中的控件222。
前后摄像头切换控件：与录像前的取景界面类似的，录制中的取景界面中也包括前后置摄像头控件。例如，前后摄像头切换控件是图2D中的(a)示出的取景界面201d中的控件223。同样的，关于前后置摄像头切换的具体内容可参见下文中实施例一的说明，此处暂不做详细说明。
面板展示控件：面板展示控件用于触发手机100展示多镜子模式的选择面板。例如，面板展示控件是图2D中的(a)示出的取景界面201d中的控件224。其中，该模式面板选择控件可以是静态的，或者，该面板展示控件也可以是动态的。若动态显示面板展示控件，可以吸引用户对该面板展示控件的关注。从而引导用户使用该控件。关于该选择面板，以及通过该选择面板切换多镜子模式的具体内容，可参见下文中实施例一的说明，此处暂不做详细说明。
模式图标：与录像前类似，录制中的取景界面中也包括模式图标。例如，模式图标是图2D中的(a)示出的取景界面201d中的控件225。
倍速标识：倍速标识用于指示手机100播放当前预览帧的倍速。例如，倍速标识是图2D中的(a)示出的取景界面201d中的标识226，该标识226指示手机100将以1倍速播放当前预览帧。应注意，在录像过程中，可以暂停录制，暂停状态下倍速标识处于不可操作的状态，如置灰状态。即，暂停状态下无法调整播放视频的倍速。
闪光灯图标：与录像前类似，录制中的取景界面中也包括闪光灯图标。应注意，视频录制过程中通常不允许调整闪光灯参数，因此，录制中的闪光灯图标是不可操作的。例如，闪光灯图标是图2D中的(a)示出的取景界面201d中的图标227，该图标227置灰，表示不可操作。
变焦控件：与录像前类似，录制中的取景界面中也包括变焦控件。例如，变焦控件是图2D中的(a)示出的取景界面201d中的变焦条228，手机100响应于用户对该变焦条228的滑动操作，可切换到相应的后置摄像头来采集预览图像。关于通过变焦条切换后置摄像头的具体内容可参加下文中关于实施例一的说明，此处暂不做详细说明。
前文中，主要以竖屏形式来说明多镜录像模式。应理解，横屏形式下也基本与竖屏形式类似。关于横屏形式与竖屏形式的细微不同之处，在下文实施例的相关内容中再做说明，此处暂不做详细说明。
下文实施例中，将结合前文对多镜录像模式的说明，并主要以多镜录像模式中的前后双镜模式、后后双镜模式、画中画模式、单前置(或后置)模式为例，来依次进一步说明多镜录像模式中的模式切换功能(如实施例一)和美颜功能(如实施例二)
实施例一，模式切换功能。
本申请实施例提供的一种视频拍摄方法，可应用于手机100。其中，在多镜录像模式的取景界面(包括录像前的取景界面和录制中的取景界面)中，手机100可以响应于用户的操作1而显示多个模式选项供用户选择。其中，每个模式选项对应一种多镜子模式。而后，手机100响应于用户对任一模式选项的选择操作，则可以切换到相应的多镜子模式。从而可以实现在录像前或者录制中灵活的切换多镜子模式。
下面分别以录像前和录制中的切换来说明本申请方案。
第一，录像前切换多镜子模式。在录像前，操作1主要是指用户对模式图标的点击操作。
本申请实施例提供一种视频拍摄方法，可以在多镜录像模式中、开始录像前切换多镜子模式。如图3A所示，该视频拍摄方法包括：
S301a、手机100显示界面a，该界面a是以子模式1录像前的取景界面。该界面a中包括子模式1的模式图标1。其中，子模式1包括前后双镜模式、后后双镜模式、画中画模式、单前置模式或者单后置模式。
S302a、手机100响应于用户对模式图标1的点击操作，在界面a中显示多个模式选项。其中，多个模式选项和多个多镜子模式一一对应。
示例性的，子模式1是前后双镜模式，则界面a可以是图2A中的(b)示出的取景界面203a，模式图标1可以是取景界面203a中的图标215。手机100响应于用户对图标215的点击操作，可在图3B中的(a)示出的取景界面203a中进一步显示选择面板310。该选择面板310中包括前后双镜模式、后后双镜模式、画中画模式、单前置模式和单后置模式共5个模式的模式选项。
在一些实施例中，每个模式选项中可以包括多镜子模式的标识，用于指示不同的多镜子模式。例如，图3B中的(a)的选择面板310中的简称“前/后”表示前后双镜模式。又如，图3B中的(a)的选择面板310中的简称“画中画”表示画中画模式。
在另一些实施例中，每个模式选中可以包括多镜子模式的布局样式，用于指示多镜子模式下摄像头采集的预览图像在取景界面中的布局。其中，手机100可以通过图片、图片大小以及图片的排列来表示布局样式。其中，图片可以是摄像头实时采集的，也可以是预先设置的。采用本实施例，可以在切换多镜子模式前，向用户提供各种多镜子模式的布局样式，可以方便快速、准确的切换。从而提高切换的效率和准确性。
例如，图3B中的(a)的选择面板310中以植物图片表示后置摄像头采集的预览图像，以人像图片表示前置摄像头采集的预览图像，则植物图片和人脸图片上下排列可以指示前后双镜模式的布局效果。
又如，图3B中的(a)的选择面板310中以植物图片表示后置摄像头采集的预览图像，以人像图片表示前置摄像头采集的预览图像，则植物图片显示在人脸图片内可以指示画中画双镜模式的布局效果。
在一些实施例中，在多个模式选项中，当前采用的多镜子模式(如子模式1)的模式选项可突出显示。从而便于指示当前采用的多镜子模式。
仍以子模式1是前后双镜模式为例，图3B中的(a)的选择面板310中。前后双镜模式的模式选项的布局样式边框加粗显示。从而达到突出的效果。
在一些实施例中，在未显示多个模式选项时，手机100以状态1显示模式图标(如模式图标1)。该情况下，手机100响应于用户对模式图标的点击操作，可显示多个模式选项。在显示多个模式选项时，手机100以状态2显示模式图标(如模式图标1)。该情况下，手机100响应于用户对模式图标的点击操作，可关闭多个模式选项的显示。例如，状态1是正常显示的状态，状态2是置灰状态。从而可以通过模式图标的显示状态来指示模式选项的显示与关闭状态，实现界面元素之间的统一。
在一些实施例中，在显示多个模式选项时，手机100关闭前后摄像头切换控件。例如，图3B中的(a)示出的取景界面203a的右下角处不再显示前后摄像头切换控件。在显示多个模式选项的情况下，用户的需求通常是通过模式选项来切换多镜子模式，而不是通过前后摄像头切换控件来切换摄像头。此时，关闭前后摄像头切换控件的显示，一方面不会影响用户的需求，另一方面可以简化界面元素，便于切换多镜子模式的操作。
上述关于S302a的说明中，主要以子模式1是前后双镜模式来说明。应理解，子模式1是后后双镜模式、画中画模式、单前置模式或者单后置模式时的原理也是类似的。下面仅简单的示出子模式1分别是后后双镜模式、画中画模式和单后置模式时，显示多个模式选项的示意图。
示例一，子模式1是后后双镜模式，则界面a可以是图2B中的(a)示出的取景界面201b，模式图标1可以是取景界面201b中的图标230。手机100响应于用户对图标230的点击操作，可在图3B中的(b)示出的取景界面201b中进一步显示选择面板311。该选择面板311中包括前后双镜模式、后后双镜模式、画中画模式、单前置模式和单后置模式共5个模式的模式选项。其中，后后双镜模式的模式选项突出显示。
示例二，子模式1是画中画模式，则界面a可以是图2B中的(b)示出的取景界面204b， 模式图标1可以是取景界面204b中的图标231。手机100响应于用户对图标231的点击操作，可在图3B中的(c)示出的取景界面204b中进一步显示选择面板312。该选择面板312中包括前后双镜模式、后后双镜模式、画中画模式、单前置模式和单后置模式共5个模式的模式选项。其中，画中画模式的模式选项突出显示。
示例三，子模式1是单后置模式(单前置时同理)，则界面a可以是图2C中的(b)示出的取景界面203c，模式图标1可以是取景界面203c中的图标232。手机100响应于用户对图标232的点击操作，可在图3B中的(d)示出的取景界面203c中进一步显示选择面板313。该选择面板313中包括前后双镜模式、后后双镜模式、画中画模式、单前置模式和单后置模式共5个模式的模式选项。其中，单后置模式的模式选项突出显示。
应注意，在一些实施例中，在子模式1是单前置模式或者单后置模式的情况下，手机100显示多个模式选项时，可以仅显示前后双镜模式、后后双镜模式和画中画模式的模式选项，同时保留前后摄像头切换控件。如此，在减少对取景界面的改动的前提下，通过多个模式选项，可以切换到前后双镜模式、后后双镜模式或者画中画模式；通过前后摄像头切换控件可以在单前置模式和单后置模式之间切换。
实际中，多个模式选项的显示可能遮挡取景界面中的预览图像，从而影响预览。
基于此，在一些实施例中，在取景界面中显示多个模式选项的情况下，手机100可响应于用户的操作(如操作2)而隐藏多个模式选项，从而灵活关闭多个模式选项的显示，避免对预览图像造成遮挡。
其中，操作2可以是用户在取景界面输入的预设手势1。例如，操作2可以是用户在图3B中的(b)示出的取景界面201b中输入的下滑手势。或者，操作2可以是用户对多个模式选项之外的，且未显示图标、控件等元素的区域的点击操作或者长按操作。或者，取景界面中包括面板隐藏控件，操作2可以是用户对面板隐藏控件的点击操作。其中，该面板隐藏控件可以是模式图标。例如，面板隐藏控件可以是图3B中的(b)示出的取景界面201b中置灰的图标314。或者，该面板隐藏控件可以是选择面板中的预设控件。例如，是面板隐藏控件可以是图3B中的(b)示出的取景界面201b中的控件3111。
在另一些实施例中，在当前的取景界面显示多个模式选项的情况下，手机100从显示该多个模式选项开始，若预设时长内未接收到用户对多个模式选项的操作，则隐藏该多个模式选项。如此，则可以在用户长时间无操作的情况下，隐藏多个模式选项，避免影响预览。
S303a、手机100响应于用户对模式选项1的选择操作，显示界面b。模式选项1对应子模式2，界面b是以子模式2录像前的取景界面。该界面b中包括子模式2的模式图标2，子模2与子模式1不同。
示例性的，以子模式1是前后双镜模式为例，手机100可以显示图3B中的(a)示出的取景界面203a，该取景界面203a中包括选择面板310。
若模式选项1是选择面板310中的选项3101，即子模式2是后后双镜模式。手机100响应于用户对该选项3101的选择操作，可显示图2B中的(a)示出的取景界面201b。
若模式选项1是选择面板310中的选项3102，即子模式2是画中画模式。手机100响应于用户对该选项3102的选择操作，可显示图2B中的(b)示出的取景界面204b。
若模式选项1是选择面板310中的选项3103，即子模式2是单后置模式。手机100响 应于用户对该选项3103的选择操作，可显示图2C中的(b)示出的取景界面203c。
若模式选项1是选择面板310中的选项3104，即子模式2是单前置模式。手机100响应于用户对该选项3104的选择操作，可显示图2C中的(a)示出的取景界面201c。
上述关于S303a的说明中，主要以子模式1是前后双镜模式来说明。应理解，子模式1是后后双镜模式、画中画模式、单前置模式或者单后置模式时的原理也是类似的。即，手机100响应于用户对任一模式选项的选择操作，则可显示该模式选项对应的子模式的取景界面。此处不再一一赘述。
应注意，前述S301a-S303a仅说明了录像前的一次切换过程，实际实施时，多个多镜子模式之间可以两两多次切换，每次的切换过程均可参见S301a-S303a的说明。在每次切换过程中，切换前的多镜子模式记为子模式1，切换后的多镜子模式记为子模式2。
综上所述，采用本实施例的方法，在进入多镜录像模式的取景界面后，开始录像前，手机100可以依据用户对多镜子模式的选择，灵活的在多个多镜子模式之间切换。从而可以在开始录像前切换到满意的多镜子模式。
第二，录制中切换多镜子模式。在录制中，操作1可以是用户对模式图标的点击操作，也可以是用户对面板展示控件的点击操作或者上滑操作。
本申请实施例提供一种视频拍摄方法，可以在多镜录像模式的录制中切换多镜子模式。在本实施例中，主要以操作1是用户对面板展示控件的上滑操作为例来说明。如图3C所示，该视频拍摄方法包括：
S301c、手机100显示界面c，该界面c是以子模式1录制中的取景界面。该界面c中包括面板展示控件。其中，子模式1包括前后双镜模式、后后双镜模式、画中画模式、单前置模式或者单后置模式。面板展示控件用于触发手机100展示选择面板，该选择面板中包括多个模式选项，多个模式选项与多个多镜子模式一一对应。
在一些实施例中，只有录制中才有面板展示控件。从而在录制中提供一种新的切换多镜子模式的快捷入口，方便录制中切换多镜子模式。例如，子模式1是前后双镜模式，则界面c可以是图2D中的(a)示出的取景界面201d，取景界面201d中包括控件224，该控件224可用于触发手机100展示选择面板。即，控件224是面板展示控件。
S302c、手机100响应于用户对面板展示控件的上滑操作，在界面c中显示多个模式选项。
示例性的，子模式1是前后双镜模式，则界面c可以是图2D中的(a)示出的取景界面201d，面板展示控件可以是取景界面201d中的控件224。手机100响应于用户对控件224的上滑操作，可在图4中的(a)示出的取景界面201d中进一步显示选择面板320。该选择面板320中包括前后双镜模式、后后双镜模式、画中画模式、单前置模式和单后置模式共5个模式的模式选项。
其中，关于选择面板、模式选项及其显示，可参见图3A所示的实施例中的相关说明，此处不再赘述。在本实施例中，主要针对录制中与录像前的不同之处进行说明。
在一些实施例中，在显示多个模式选项时，手机100则隐藏面板展示控件。例如，图4中的(a)示出的取景界面201d中不再显示面板展示控件。如此，可以简化界面元素。
在一些实施例中，与录像前类似的，在显示多个模式选项时，手机100关闭前后摄像头切换控件。例如，图4中的(a)示出的取景界面201d的右下角处不再显示前后摄像头 切换控件。
上述关于S302c的说明中，主要以子模式1是前后双镜模式来说明。应理解，子模式1是后后双镜模式、画中画模式、单前置模式或者单后置模式时的原理也是类似的。下面仅简单的示出子模式1分别是后后双镜模式、画中画模式和单后置模式时，显示多个模式选项的示意图。
示例一，子模式1是后后双镜模式，则界面c可以是图2D中的(b)示出的取景界面204d，面板展示控件可以是取景界面204d中的控件240。手机100响应于用户对控件240的上滑操作，可在图4中的(b)示出的取景界面204d中进一步显示选择面板321。该选择面板321中包括前后双镜模式、后后双镜模式、画中画模式、单前置模式和单后置模式共5个模式的模式选项。其中，后后双镜模式的模式选项突出显示。
示例二，子模式1是画中画模式，则界面c可以是图2D中的(c)示出的取景界面207b，面板展示控件可以是取景界面207d中的控件241。手机100响应于用户对控件241的上滑操作，可在图4中的(c)示出的取景界面207d中进一步显示选择面板322。该选择面板322中包括前后双镜模式、后后双镜模式、画中画模式、单前置模式和单后置模式共5个模式的模式选项。其中，画中画模式的模式选项突出显示。
示例三，子模式1是单前置模式(单后置时同理)，则界面a可以是图2E中的(a)示出的取景界面201e，面板展示控件可以是取景界面201e中的控件242。手机100响应于用户对控件242的上滑操作，可在图4中的(d)示出的取景界面201e中进一步显示选择面板323。该选择面板323中包括前后双镜模式、后后双镜模式、画中画模式、单前置模式和单后置模式共5个模式的模式选项。其中，单前置模式的模式选项突出显示。
应注意，在一些实施例中，与录像前类似的，在子模式1是单前置模式或者单后置模式的情况下，手机100显示多个模式选项时，可以仅显示前后双镜模式、后后双镜模式和画中画模式的模式选项，同时保留前后摄像头切换控件。
在录制中显示多个模式选项时，多个模式选项也会遮挡取景界面中的预览图像，从而影响预览。因此，手机100也可以采用与录像前类似的方式来隐藏多个模式选项，此处不再赘述。
S303c、手机100响应于用户对模式选项1的选择操作，显示界面d。模式选项1对应子模式2，界面d是以子模式2录制中的取景界面。子模2与子模式1不同。
该S303c的实现原理和过程，与前文S303a类似，具体可参见前文S303a的说明。此处不再赘述。唯一需要注意的是，该界面d是录制中的取景界面，而S303a中的界面b是录像前的取景界面。
应注意，前述S301c-S303c仅说明了录像前的一次切换过程，实际实施时，多个多镜子模式之间可以两两多次切换，每次的切换过程均可参见S301c-S303c的说明。在每次切换过程中，切换前的多镜子模式记为子模式1，切换后的多镜子模式记为子模式2。
综上所述，采用本实施例的方法，在进入多镜录像模式的取景界面，并开始录制后，手机100可以依据用户对多镜子模式的选择，灵活的在多个多镜子模式之间切换。
前述图3C所示的实施例主要以操作1是用户对面板展示控件的点击操作来说明录制中的切换过程。在另一些实施例中，操作1是用户对模式图标的点击操作的实现原理也相同，而只是触发显示多个模式选项的条件不同，此处将不再赘述。另外，在录制中，可以 将上述两种操作1的形式结合。从而可以通过多种方式触发显示多个模式选项，提高切换的灵活性。
应注意，录像前的切换过程不会体现在最终形成的视频文件中。例如，录像前从前后双镜模式切换后后后双镜模式，而后开始录制，则在最终形成的视频文件中不会包括录像前从前后双镜模式切换到后后双镜模式的过程，而只会呈现以后后双镜模式录制的视频。
与上述录像前的切换不同的是，录制中的切换过程会体现在最终形成的视频文件中。示例性的，在S303c之后，手机响应于用户对界面d的操作3，生成视频文件1。该操作3用于触发手机结束视频录制。例如，操作3可以是用户对结束录制控件的点击操作。该视频文件1包括视频流a和视频流b。其中，视频流a是以子模式1录制视频形成的视频流，视频流b是以子模式2录制视频形成的视频流。
进一步的，视频流a可以由n个子视频流组成，n是正整数，n的值等于子模式1采用的摄像头的数量。n个子视频流与子模式1采用的n个摄像头对应。即，n个子视频流中每个子视频流由子模式1采用的相应摄像头采集的多帧预览图像构成。同样的，视频流b可以由m个子视频流组成，m是正整数，m的值等于子模式2采用的摄像头的数量。m个子视频流与子模式2采用的m个摄像头对应。即，m个子视频流中每个子视频流由子模式2采用的相应摄像头采集的多帧预览图像构成。
示例性的，以子模式1是前后双镜模式，子模式2是后后双镜模式，并且录制视频过程中切换一次多镜子模式为例。如图5所示，从00:00：00(第0秒开始)到00:09:59(第9秒结束)的前10秒钟内，采用后置主摄像头和前置摄像头以前后双镜模式录制视频。在00:09:59(或00:10:00)，手机100将多镜子模式切换为后后双镜模式，采用后置长焦摄像头和后置广角摄像头采集预览图像。而后，从00:10:00(第10秒开始)到00:14:59(第14秒结束)的5秒钟内，以后后双镜模式录制视频。在00:14:59，手机100结束视频录制，生成视频文件1。视频文件1包括视频流a1、视频流a2、视频流b1和视频流b2。其中，视频流a1包括前后双镜模式下后置主摄像头采集的多帧预览图像，视频流a2包括前后双镜模式下前置摄像头采集的多帧预览图像。也就是说，视频流a包括两个子视频流，即，视频流a1和视频流a2。视频流b1包括后后双镜模式下后置长焦摄像头采集的多帧预览图像，视频流b2包括后后双镜模式下后置广角摄像头采集的多帧预览图像。也就是说，视频流b包括两个子视频流，即，视频流b1和视频流b2。
综上所述，在录制过程中切换多镜子模式，可以录制得到由多种多镜子模式下录制得到的视频流构成的视频文件。从而可以提高视频录制的灵活性和多样性。
进一步的，在录制中的一些场景中，需要同时显示变焦控件和面板展示控件，并且面板展示控件可能与变焦控件邻近。例如，在图2D中的(c)示出的画中画模式的录制中的取景界面207d中，面板展示控件241和变焦控件243相邻显示。又如，在图2E中的(b)示出的单后置模式的录制中的取景界面203e中，面板展示控件244和变焦控件245相邻显示。
针对上述场景，在一些实施例中，通过为不同的控件划分互不干扰的响应机制，以准确响应用户的操作。在一种具体的实现方式中，在单后置模式或者画中画模式录制中的取景界面中，面板展示控件的响应热区(简称为面板展示热区，其中包括面板展示控件)包括变焦控件的响应热区(简称为变焦热区，其中包括变焦控件)。其中，在面板展示热区 内，用户输入滑动操作的起点和终点之间的连线，与屏幕的底部之间的最小夹角大于预设角度(如60°)时，才能触发手机100展示选择面板，以供切换多镜子模式。在变焦热区内，用户输入滑动操作的起点和终点之间的连线，与屏幕的底部之间的最小夹角小于或等于预设角度(如60°)时，才能触发手机100切换后置摄像头。应理解，由于面板展示热区包括变焦热区，则在变焦热区内，就意味着在面板展示区域内。
在该实现方式中，面板展示热区较大，可以方便用户触发手机100展示选择面板。从而可以降低多镜子模式的切换难度。同时，手机100以用户输入滑动操作的起点和终点之间的连线，与屏幕的底部之间的最小夹角的大小，来响应用户的操作，可以准确的响应用户的操作，且不会发生混乱。
示例性的，以单后置模式、预设角度是60°为例。如图2F中的(a)所示，在单后置模式录制中的取景界面中，面板展示热区包括变焦热区，例如，面板展示热区的高度为60像素(dp)，宽度为屏幕的宽度，变焦热区的高度为130dp，宽度也是屏幕的宽度。滑动操作1由起点A，沿着箭头1，滑动到终点B，由于A点和B点都在面板展示热区，且A点和B点的连线与屏幕底部的最小夹角大于60°，相应的，手机100响应于该滑动操作1，可以展示选择面板，以供切换多镜子模式。滑动操作2由起点A，沿着箭头2，滑动到终点C，由于A点和C点都在变焦热区，且A点和C点的连线与屏幕底部的最小夹角小于60°，相应的，手机100响应于该滑动操作2，可以切换采集图像的后置摄像头。
另外，在录制前或者录制中的另一些场景中，如在前后双镜模式、后后双镜模式录制中的取景界面中，又如在各种多镜子模式录制前的取景界面中，面板展示控件的邻近位置并未显示变焦控件。在这些场景中，单独为面板展示控件划分相应的热区即可。其中，针对动态的面板展示控件和静态的面板展示控件，可设置不同的面板展示热区。例如，为动态的面板展示控件设置更大的面板展示热区。
示例性的，以前后双镜模式为例。如图2F中的(b)所示，在前后双镜模式录制中的取景界面中，面板展示控件和变焦控件相隔较远，则可以设置面板展示热区为如图所示的矩形区域，如高度为60dp，宽度为屏幕的宽度。
前文关于实施例一的说明中，主要通过模式图标或者面板展示控件来切换多镜子模式，但是实际实施时，并不以此为限。在一些实施例中，还可以通过预设手势来触发切换多镜子模式。示例性的，竖屏形式下，在采用单个摄像头采集图像的模式的情况下，手机100响应于用户从屏幕的下边缘或者上边缘往屏幕中间的滑动手势，可以从采用单个摄像头采集图像的模式，切换为采用两个摄像头采集图像的模式。如，切换为前后双镜模式。又示例性的，竖屏形式下，在采用两个摄像头采集图像的模式的情况下，手机100响应于用户从两个预览图像的相交区域附近的位置向屏幕的上边缘或者下边缘的滑动手势，可以从采用两个摄像头采集图像的模式，切换为采用单个摄像头采集图像的模式。在本实施例中，通过预设手势可以直接触发手机100切换多镜子模式，无需展示模式选项，从而可以提高切换的便捷性。
在下文实施例中，将主要以通过模式图标和面板展示控件来切换多镜子模式的方式来说明本申请方案。
前述实施例一中，主要通过模式选项来切换多镜子模式，即切换摄像头、布局等。
在一些实施例中，为了进一步提高切换的便捷性，还提供有如下切换方式：
方式一，通过前后摄像头切换控件来触发手机100切换前置摄像头和后置摄像头。
示例性的，在单前置模式下，手机100响应于用户对前后摄像头切换控件的点击操作，可以切换到单后置模式。或者，在单后置模式下，手机100响应于用户对前后摄像头切换控件的点击操作，可以切换到单前置模式。
又示例性的，在前后双镜模式或者画中画模式中，手机100响应于用户对前后摄像头切换控件的点击操作，可以将其中的前置摄像头切换为后置摄像头(如后置主摄像头)。
再示例性的，在后后双镜模式中，手机100响应于用户对前后摄像头切换控件的点击操作，可以将其中一个后置摄像头切换为前置摄像头，从而切换为前后双镜模式。例如，手机100响应于用户对图2D中的(b)示出的取景界面204d中前后摄像头切换控件的点击操作，可以显示图2D中的(a)示出的取景界面201d。
方式二，在当前采用的摄像头有后置摄像头的情况下，可以通过变焦控件来触发手机100切换后置摄像头。
示例性的，在单后置模式下，手机100响应于用户对变焦控件中变焦倍速的选择操作，可以切换到相应的后置摄像头。例如，当选择2倍倍率时，手机100可以切换到后置2倍长焦镜头。
又示例性的，在前后双镜模式或者画中画模式中，手机100响应于用户对变焦控件中变焦倍速的选择操作，可以将当前的后置摄像头切换为其他的后置摄像头。例如，手机100响应于用户对图2D中的(a)示出的取景界面201d中变焦条228的滑动操作，可将当前采用的后置摄像头(如后置主摄像头)切换为其他的后置摄像头。如从1x滑动到2x，则可以从后置主摄像头切换到后置2倍长焦摄像头。
再示例性的，在后后双镜模式中，手机100响应于用户对变焦控件中变焦倍率的选择操作，可以将其中一个后置摄像头切换为其他的后置摄像头。例如，手机100响应于用户对图2D中的(b)示出的取景界面204d中变焦条的滑动操作，可以将预览图像显示在上方的后置摄像头(如后置2倍长焦摄像头)切换为其他的后置摄像头。如从2x滑动到4x，则可以从后置2倍长焦摄像头切换到后置4倍长焦摄像头。
方式三，通过手指缩放来触发后置摄像头的切换。例如，手指打开，则触发切换至后置长焦摄像头。打开程度越大，则切换至倍率更大的后置长焦摄像头。手指捏合，则触发切换至广角摄像头。
应注意，若前置摄像头有多个，也可以通过方式二或者方式三来切换。
方式四，通过对双景取景界面中的预览图像的双击操作来对调两个摄像头采集的预览图像的显示区域。
示例性的，在前后双镜模式下，手机100响应于用户对任一预览图像的双击操作，可以对调前置摄像头采集的预览图像和后置摄像头采集的预览图像的显示区域。例如，手机100响应于用户对图2D中的(a)示出的取景界面201d中预览图像202d或者预览图像203d的双击操作，可以对调预览图像202d和预览图像203d的显示区域。对调后，预览图像202d显示在预览图像203d的下方。
又示例性的，在后后双镜模式下，手机100响应于用户对任一预览图像的双击操作，可以对调两个后置摄像头采集的预览图像的显示区域。例如，手机100响应于用户对图2D中的(b)示出的取景界面204d中预览图像205d或者预览图像206d的双击操作，可以对 调预览图像205d和预览图像206d的显示区域。对调后，预览图像205d显示在预览图像206d的下方。
再示例性的，在画中画模式下，手机100响应于用户对任一预览图像的双击操作，可以对调前置摄像头采集的预览图像和后置摄像头采集的预览图像的显示区域。例如，手机100响应于用户对图2D中的(c)示出的取景界面207d中预览图像208d或者预览图像209d的双击操作，可以对调预览图像208d和预览图像209d的显示区域。对调后，预览图像208d显示在小窗209D中，预览图像209d显示在大窗208D中。
方式五，在画中画模式下，通过手指缩放小窗窗口或者拖拽小窗边缘可以触发手机100缩放小窗的窗口尺寸。
实施例二、美颜功能。
本申请实施例提供的一种视频拍摄方法，可应用于手机100。其中，在多镜录像模式中，录像前的取景界面中，手机100可以响应于用户对取景界面中美颜控件(也可以称为第一控件)的操作(如点击操作)而显示一个或多个美颜效果控件，供用户选择美颜效果。而后，手机100响应于用户对美颜效果控件的操作，则可以设置多镜录像模式的美颜效果。从而可以在多镜录像模式的录像前，完成美颜设置。
示例性的，美颜控件是图2A中的(b)示出的取景界面203a中的控件213。手机100响应于用户对图2A中的(b)示出的取景界面203a中的控件213的点击操作，可以在图6A中的(a)示出的取景界面203a中进一步显示美颜调节条601，该美颜调节条601记为美颜效果控件。如图6A中的(a)所示，美颜调节条601中默认的美颜级别是5级。而后，手机100可接收用户对美颜调节条601的滑动操作，即，对美颜级别的选择操作。如图6A中的(b)所示，手机100可接收用户对美颜调节条601中级别6的选择操作。手机100响应于用户对级别6的选择操作，可以调整美颜效果为6级美颜的效果。
应注意，上述图6A中的(a)和图6A中的(b)的举例中，仅以美颜效果控件是美颜调节条为例，来说明了手机100设置美颜效果的实现。实际中，美颜效果控件还可以是其他形式的。例如，美颜效果控件也可以是多个效果选项，多个效果选项与多种美颜效果一一对应。在本文实施例中，主要以美颜效果控件是美颜调节条为例来说明本申请方案。
在一些实施例中，在用户操作美颜调节条而调整美颜级别的过程中，手机100仅显示预览图像和美颜调节条。而隐藏取景界面中的其它元素。从而可以方便用户准确的调节美颜级别。例如，如图6A中的(b)所示，在用户操作美颜调节条的过程中，手机100隐藏模式图标、闪光灯图标、开始录制控件、前后摄像头切换控件等界面元素，而仅显示预览图像和美颜调节条。
应注意，多镜录像模式中，在采用两个及以上摄像头采集图像的多镜子模式中，例如前后双镜模式、后后双镜模式或者画中画模式中，通常仅在拍摄对象为人像时，才存在美颜需求。与此同时，在采用两个及以上摄像头采集图像时，通常使用前置摄像头来采集人像。基于此，在一些实施例中，在采用两个及以上摄像头采集图像的多镜子模式中，仅有前置摄像头采集的图像支持美颜。进一步，在本实施例中，手机100可以将美颜控件显示在取景界面中前置摄像头的图像附近。如此，便于明确美颜针对的对象。
例如，图2A中的(b)示出的取景界面203a中包括控件213，该控件214用于触发手机100调节美颜级别。即，控件213是美颜控件。该控件213显示在前后双镜模式下前置 摄像头采集的图像(如人脸图像)的显示区域内。又如，图2B中的(b)示出的取景界面204b中包括美颜控件，且该美颜控件显示在画中画模式下前置摄像头采集的图像(如人脸图像)的显示区域(如小窗)的下方。
在本实施例中，前后双镜模式和画中画模式中，前置摄像头采集的图像(通常为人像)支持美颜，则在通过美颜控件设置美颜效果后，仅有前置摄像头采集的图像可以添加该美颜效果。也就是说，在前后双镜模式和画中画模式中，美颜控件仅用于设置前置摄像头采集的图像的美颜效果。
示例性的，以图2A中的(b)示出的前后双镜模式录像前的取景界面为例，在通过控件213(即美颜控件)设置美颜效果为6级美颜后，手机100可显示图6B示出的取景界面602，该取景界面602中仅有前置摄像头采集的预览图像604添加有6级美颜的美颜效果，而后置摄像头采集的预览图像603并未添加美颜效果。
另外，在采用两个及以上摄像头采集图像的多镜子模式中，若当前采用的多镜子模式下，采集图像的摄像头不包括前置摄像头(例如后后双镜模式)，手机100则可以不显示美颜控件，或者将美颜控件默认显示在手机100的底部附近的位置。例如，图2B中的(a)示出的取景界面201b为后后双镜模式的取景界面，后后双镜模式中采集图像的摄像头是两个后置摄像头，即不包括前置摄像头，手机100则可将美颜控件显示手机100的底部附近的位置。
或者，在单前置模式或者单后置模式中，都有可能使用当前的单个摄像头来采集人像，因此都可能存在美颜的需求。基于此，在一些实施例中，前置摄像头和后置摄像头均支持美颜。进一步的，在单前置模式或者单后置模式中，手机100均可以在取景界面中显示美颜控件。并且，在通过美颜控件设置美颜效果后，美颜效果可以添加在全屏显示的预览图像上。
也就是说，常见的多镜子模式中，单前置模式和单后置模式支持美颜，前后双景模式和画中画模式中前置摄像头采集的图像支持美颜(也可以称为部分支持美颜)，后后双镜模式通常不支持美颜。而基于前述实施例一的说明可知，在多镜录像模式中，手机100可以在多个多镜子模式中两两之间切换。以此为前提，则可能从支持美颜的模式(如单后置模式)切换到部分支持美颜或者不支持美颜的模式；或者，也可能从部分支持美颜的模式切换为不支持美颜的模式。
基于此，本申请实施例提供了一种视频拍摄方法，可以应用于手机100。在本实施例中，手机100可以根据切换前后的多镜子模式，来智能的设置美颜效果，以适配多镜子模式对美颜的支持情况。下面以几种典型的场景来说明智能设置美颜效果的具体实现：
场景1，从采用单个摄像头采集图像的模式切换到采用两个摄像头采集图像，且切换后的两个摄像头中包括后置摄像头。
请参见图6C，为本申请实施例提供的一种视频拍摄方法的流程图，可以应用于手机100。在本实施例中，主要以场景1为例，来说明智能设置美颜效果的具体实现。
如图6C所示，本实施例的视频拍摄方法可以包括：
S611、手机100显示界面a，界面a是采用第一摄像头录像的取景界面。该界面a中包括全屏显示的第一预览图像。其中，第一预览图像是手机100对第一摄像头采集的第一图像添加第一美颜效果后得到的。第一摄像头是前置摄像头或者后置摄像头。
其中，录像的取景界面可以是录像前的取景界面，也可以是正在录像的取景界面。即，界面a(也可以称为第一界面)可以是录像前的取景界面，也可以是正在录像的取景。也就是说，在录像前和正在录像的过程中，都可以采用本实施例的方法来智能设置美颜效果。
在一些实施例中，界面a中的美颜效果是手机100根据用户对美颜控件和美颜效果控件的操作，而设置的。
在本实施例中，在S611之前，手机100需要根据用户对美颜控件和美颜效果控件的操作，设置采用第一摄像头录像的美颜效果为第一美颜效果。具体设置美颜效果的过程前文已说明，此处不再赘述。在完成美颜效果设置后，手机100则可显示界面a，界面a中的预览图像具有第一美颜效果。即，界面a是录像前的取景界面的情况。或者，在完成美颜设置后，手机100响应于用户开始录制视频的操作(如点击开始录制控件的操作)，可显示界面a，界面a中的预览图像具有第一美颜效果。即，界面a是正在录像的取景界面的情况。下文实施例中，将主要以界面a是正在录像的取景界面为例来说明本申请方案。
在另一些实施例中，界面a中的美颜效果，可以是手机100在采用本申请方案之后，根据多镜子模式的切换，而智能的设置美颜效果的结果。
示例性的，在一种场景中，第一摄像头可以是前置摄像头，则界面a可以是图6D中的(a)示出的取景界面621，第一预览图像可以是该取景界面621中包括预览图像622，该预览图像622是手机100对前置摄像头采集的图像添加第一美颜效果(如6级美颜)后得到的。
示例性的，在另一种场景中，第一摄像头也可以是后置摄像头，则界面a可以是图6D中的(b)示出的取景界面623，第一预览图像可以是该取景界面623中包括预览图像624，该预览图像624是手机100对后置摄像头采集的图像添加第一美颜效果(如6级美颜)后得到的。
S612、手机100响应于用户对界面a的操作1，在界面a中显示多个模式选项。其中，多个模式选项与多个多镜子模式一一对应。
在S612之前，手机100可接收用户对界面a的操作1。
S613、手机100响应于用户对模式选项1的选择操作，显示界面b。模式选项1对应采用第二摄像头和第三摄像头采集图像的模式，界面b是采用第二摄像头和第三摄像头采集图像的取景界面，界面b中包括处理第二摄像头采集的第二图像得到的第二预览图像和处理第三摄像头采集的第三图像得到的第三预览图像。第二预览图像和第三预览图像中后置摄像头采集的预览图像未添加美颜效果。
在S613之前，手机100可接收用户对模式选项1的选择操作。
关于切换多镜子模式(如S612-613中从采用单个摄像头采集图像的模式切换到采用两个摄像头采集图像的模式)的具体实现，可参见前文实施例一中的相关说明，此处不再赘述。另外，为了方便说明，可以将触发手机100从采用单个摄像头采集图像切换到采用两个摄像头(第二摄像头和第三摄像头)采集图像的操作，称为第一操作。例如，用户对模式选项1的选择操作为第一操作。同样为了方便说明，界面b可以称为第二界面。
其中，模式选项1可以对应前后双镜模式，即第二摄像头可以是前置摄像头，第三摄像头可以是后置摄像头。相应的，界面b是前后双镜模式的取景界面。进一步的，针对不同的第一摄像头，手机100智能设置美颜效果的结果具体如下：
第一种，第一摄像头为前置摄像头。
前后双镜模式中的后置摄像头不支持美颜，则第三摄像头采集的第三图像不能使用美颜效果。同时，第一摄像头是前置摄像头，则第二摄像头采集的第二图像可以继续沿用第一美颜效果。也就是说，第一摄像头是前置摄像头，第二摄像头是前置摄像头，第三摄像头是后置摄像头，界面b中包括第二预览图像和第三预览图像，则第二预览图像添加有第一美颜效果，第三预览图像未添加美颜效果。即，前置摄像头采集的图像沿用切换前的美颜效果，而后置摄像头采集的图像不使用美颜效果。
示例性的，界面a是图6D中的(a)示出的单前置模式的取景界面621，在切换为前后双镜模式后，手机100可以显示图6E中的(a)示出的前后双镜模式的取景界面625，即取景界面625是界面b。该取景界面625中包括预览图像627和预览图像626，预览图像627是第二预览图像，预览图像626是第三预览图像。预览图像627添加有第一美颜效果，预览图像626未添加美颜效果。
第二种，第一摄像头为后置摄像头。
前后双镜模式中的后置摄像头不支持美颜，则第三摄像头采集的第三图像不能使用美颜效果。同时，第一摄像头是后置摄像头，则第二摄像头采集的第二图像不能沿用切换前后置摄像头的美颜效果。也就是说，第一摄像头是后置摄像头，第二摄像头是前置摄像头，第三摄像头是后置摄像头，界面b中包括第二预览图像和第三预览图像，则第二预览图像和第三预览图像均未添加美颜效果。即，前置摄像头采集的图像不使用美颜效果，后置摄像头采集的图像也不再沿用切换前的美颜效果。
示例性的，界面a是图6D中的(b)示出的单后置模式的取景界面623，在切换为前后双镜模式后，手机100可以显示图6E中的(b)示出的前后双镜模式的取景界面628，即取景界面628是界面b。该取景界面628中包括预览图像630和预览图像629，预览图像630是第二预览图像，预览图像629是第三预览图像。其中，预览图像630和预览图像629中均未添加美颜效果。
其中，模式选项1可以对应画中画模式，第二摄像头可以是前置摄像头，第三摄像头可以是后置摄像头。相应的，界面b是前后双镜模式的取景界面。进一步的，针对不同的第一摄像头，手机100智能设置美颜效果的结果也不同，其具体与前后双镜模式类似。具体原理可参见前文关于前后双镜模式中智能设置美颜效果的说明，此处将不再赘述，而仅以如下两个示例来说明。
示例一，第一摄像头为前置摄像头，界面a可以是图6D中的(a)示出的单前置模式的取景界面621，在切换为画中画模式后，手机100可以显示图6F中的(a)示出的画中画模式的取景界面631，即取景界面631是界面b。该取景界面631中包括预览图像632和预览图像633。预览图像632是第二预览图像，预览图像633是第三预览图像。其中，预览图像632添加有第一美颜效果，预览图像633未添加美颜效果。
示例二，第一摄像头为后置摄像头，界面a是图6D中的(b)示出的单后置模式的取景界面623，在切换为画中画模式后，手机100可以显示图6F中的(b)示出的画中画模式的取景界面634，即取景界面634是界面b。该取景界面634中包括预览图像635和预览图像636，预览图像635是第二预览图像，预览图像636是第三预览图像。其中，预览图像635和预览图像636中均未添加美颜效果。
其中，模式选项1可以对应后后双镜模式，即第二摄像头和第三摄像头都是后置摄像头。相应的，界面b是后后双镜模式的取景界面。进一步的，后后双镜模式中两个后置摄像头采集的图像都不支持美颜，则无论第一摄像头是前置摄像头还是后置摄像头，第二预览图像和第三预览图像中均未添加美颜。
示例性的，以第一摄像头是后置摄像头为例，界面a是图6D中的(b)示出的单后置模式的取景界面623，在切换为后后双镜模式后，手机100可以显示图2D中的(b)示出的取景界面204d，即取景界面204d是界面b。该取景界面204d中包括预览图像205d和预览图像206d，预览图像205d是第二预览图像，预览图像206d是第三预览图像。由于后后双镜模式中的后置摄像头均不支持美颜，则切换前后置摄像头的美颜效果无法沿用到后后双镜模式中。即，预览图像205d和预览图像206d均未添加美颜效果。
进一步的，在一些实施例中，在从采用单个摄像头采集图像的模式，切换为采用两个摄像头采集图像的模式后，手机100可以智能的针对不同的摄像头采集的图像添加美颜效果。而后，手机100可以再次切换回采用单个摄像头采集图像的模式。针对这种情况，在本实施例中，视频拍摄方法还包括：
S614、手机100响应于用户对界面b的操作1，在界面b中显示多个模式选项。
S615、手机100响应于用户对模式选项2的选择操作，显示界面c。模式选项2对应采用第四摄像头采集图像的模式，界面c是采用第四摄像头录像的取景界面。界面c中包括全屏显示的第四预览图像，第四预览图像是手机100对第四摄像头采集的第四图像添加第一美颜效果后得到的。
其中，第四摄像头可以与第一摄像头相同，也可以与第一摄像头不同。例如，第一摄像头是后置主摄像头，第四摄像头可以是后置主摄像头，也可以是前置摄像头。
通过上述S614-S615，手机100可以从采用两个摄像头采集图像的模式，再次恢复为采用单个摄像头采集图像的模式，在切换后，可以显示界面c。在界面c中，可以为单个摄像头采集的图像添加第一美颜效果。另外，为了方便说明，可以将界面c称为第三界面，将触发手机100从采用两个摄像头采集图像切换为采用单个摄像头采集图像的操作(如用户对模式选项2的选择操作)称为第二操作。
示例性的，以界面b是图6E中的(a)示出的取景界面625为例，在切换为单前置模式后，手机100可以显示图6D中的(a)示出的取景界面621，即取景界面621是界面c。该取景界面621中的预览图像622添加有第一美颜效果，即预览图像622是第四预览图像。
综上所述，采用本实施例的方法，在录像前的取景界面或者在正在录像的取景界面中，手机100可以在从采用单个摄像头采集图像的模式，切换为采用两个摄像头采集图像的模式后，智能的设置两个摄像头分别采集的图像的美颜效果。从而提高美颜设置的合理性。
场景2，从采用一个前置摄像头和一个后置摄像头采集图像(如前后双镜模式或者画中画模式)切换到采用两个后置摄像头采集图像(如后后双镜模式)。
请参见图6G，为本申请实施例提供的一种视频拍摄方法的流程图，可以应用于手机100。在本实施例中，主要以场景2为例，来说明智能设置美颜效果的具体实现。
如图6G所示，本实施例的视频拍摄方法可以包括：
S641、手机100显示界面a，界面a是以前后双镜模式或者画中画模式录像的取景界面。该界面a中包括第一预览图像和第五预览图像。第一预览图像是手机100对第一摄像 头采集的第一图像添加第一美颜效果后得到的，第二预览图像未添加美颜效果。
示例性的，界面a可以是图6E中的(a)示出的前后双镜模式的取景界面625，该取景界面625中包括预览图像626和预览图像627，预览图像627是第一预览图像，预览图像626是第五预览图像。预览图像627添加有第一美颜效果，预览图像626未添加美颜效果。
也就是说，在本实施例中，切换前的前后双镜模式中，为前置摄像头采集的图像添加了第一美颜效果。同样的，该界面a中的美颜效果可以是根据用户对美颜控件和美颜效果控件的操作而设置的，也可以是在采用本申请方案之后，根据多镜子模式的切换而智能设置的。
S642、手机100响应于用户对界面a的操作1，在界面a中显示多个模式选项。其中，多个模式选项与多个多镜子模式一一对应。
S643、手机100响应于用户对模式选项1的选择操作，显示界面b。模式选项1对应后后双镜模式，界面b是以后后双镜模式录像的取景界面。界面b中包括第二预览图像和第三预览图像，第二预览图像是手机100处理第二摄像头采集的第二图像得到，第三预览图像是手机100处理第三摄像头采集的第三图像得到的。第二预览图像和第三预览图像均未添加美颜效果。
由于后后双镜模式完全不支持美颜，则在从前后双镜模式或者画中画模式切换到后后双镜模式后，手机100则需关闭切换前前置摄像头的美颜效果(如第一美颜效果)。
示例性的，界面a是图6E中的(a)示出的前后双镜模式的取景界面625，第一预览图像是预览图像627，该预览图像627具有第一美颜效果；第五预览图像是预览图像626，预览图像626不具有第一美颜效果。在切换为后后双镜模式后，手机100可以显示图2D中的(b)示出的取景界面204d，即取景界面204d是界面b。该取景界面204d中包括预览图像205d和预览图像206d，预览图像205d是第二预览图像，预览图像206d是第三预览图像。由于后后双镜模式中的后置摄像头均不支持美颜，则预览图像205d和预览图像206d均未添加美颜效果。
进一步的，在一些实施例中，在从采用一个前置摄像头和一个后置摄像头采集图像切换到采用两个后置摄像头采集图像后，手机100可以智能的关闭美颜效果。而后，手机100可以再次切换回采用一个前置摄像头和一个后置摄像头采集图像。针对这种情况，在本实施例中，视频拍摄方法还包括：
S644、手机100响应于用户对界面b的操作1，在界面b中显示多个模式选项。
S645、手机100响应于用户对模式选项3的选择操作，显示界面d。界面d是前后双镜模式或者画中画模式的取景界面。界面d中包括第六预览图像和第七预览图像，第六预览图像是对第六摄像头采集的第六图像添加第一美颜效果得到的，第七预览图像是处理第七摄像头采集的第七图像得到的。第六摄像头是前置摄像头，第七摄像头是后置摄像头，第七预览图像未添加美颜效果。
也就是说，模式选项3对应采用前后双镜模式或者画中画模式。
其中，第六预览图像和第七预览图像在界面d中的显示布局，可以与第一预览图像和第五预览图像在界面a中的显示布局相同。示例性的，均为分屏布局或者均为画中画布局。或者，第六预览图像和第七预览图像在界面d中的显示布局，可以与第一预览图像和第五 预览图像在界面a中的显示布局相同。示例性的，第六预览图像和第七预览图像在界面d中为分屏布局，第一预览图像和第五预览图像在界面a为画中画布局。如，界面a为图6E中的(a)示出的前后双镜模式的取景界面625，界面d为图6F中的(a)示出的画中画模式的取景界面631。又示例性的，第六预览图像和第七预览图像在界面d中为画中画布局，第一预览图像和第五预览图像在界面a为分屏布局。如，界面a为图6F中的(a)示出的画中画模式的取景界面631，界面d为图6E中的(a)示出的前后双镜模式的取景界面625。
在本实施例中，在从采用一个前置摄像头和一个后置摄像头采集图像切换到采用两个后置摄像头采集图像后，手机100可以取消美颜效果；而后，再次切回采用一个前置摄像头和一个后置摄像头采集图像后，手机100可以显示界面d。在界面d中，可以恢复为前置摄像头采集的图像添加美颜效果。另外，为了方便说明，界面d也可以称为第四界面，触发手机100从采用两个后置摄像头采集图像切换为采用一个前置摄像头和一个后置摄像头采集图像的操作(如用户对模式选项3的选择操作)可以称为第三操作。
示例性的，界面b是图2D中的(b)示出的后后双镜模式的取景界面204d，在切换为采用一个前置摄像头和一个后置摄像头采集图像后，例如，切回画中画模式后，手机100可显示图6F中的(a)示出的取景界面631。取景界面631中包括预览图像632和预览图像633，预览图像632为第六预览图像，预览图像633为第七预览图像。预览图像632添加有第一美颜效果。
综上所述，采用本实施例的方法，在录像前的取景界面或者在正在录像的取景界面中，手机100可以在从采用一个前置摄像头和一个后置摄像头采集图像，切换为采用两个后置摄像头采集图像后，智能的关闭美颜效果。从而提高美颜设置的合理性。
在上述场景1和场景2的一些实施例中，在手机100智能的关闭掉全部或者部分摄像头采集的图像的美颜效果后，手机100还可以进一步在界面b中显示提示1。该提示1用于提示已关闭美颜。
示例性的，界面a是图6D中的(b)示出的单后置模式的取景界面623。该取景界面623中的预览图像624添加有第一美颜效果，即为后置摄像头采集的图像添加了第一美颜效果。而后，手机100切换为前后双镜模式，则界面b可以是图6H示出的取景界面651。该取景界面651中包括预览图像652、预览图像653和提示654。预览图像651和预览图像652均未添加美颜效果，即关闭了第一美颜效果。提示654具体为：采用两个摄像头录像时，后置摄像头不支持美颜，用于提示已关闭美颜。即，提示654是提示1。
应注意，在进入多镜录像模式至退出多镜录像模式的一次录像过程中，手机100仅在智能设置美颜效果的过程中，第一次关闭美颜效果时，显示提示1。此后则不再显示。从而避免影响预览。
场景3，从采用一个前置摄像头和一个后置摄像头采集图像切换到采用单个摄像头采集图像。
其中，采用一个前置摄像头和一个后置摄像头采集图像的模式可以为前后双镜模式或者画中画模式。下文关于场景3的说明中，主要以前后双镜模式为例来说明，画中画模式的原理与之类似，本文中将不再赘述。
切换前是前后双镜模式，并且为前置摄像头采集的图像添加了第一美颜效果。若切换后是单前置模式，则可以继续沿用第一美颜效果。即，切换后的取景界面中，预览图像添 加有第一美颜效果。若切换后是单后置模式，则取消第一美颜效果。即，切换后的取景界面中，预览图像未添加第一美颜效果。
示例性的，切换前是前后双镜模式，并且为前置摄像头采集的图像添加了第一美颜效果，则手机100可以显示图6E中的(a)示出的前后双镜模式的取景界面625。该取景界面625中的预览图像627添加有第一美颜效果，即为前置摄像头采集的图像添加了第一美颜效果。若切换后的是单前置模式，则手机100可以显示图6D中的(a)示出单后置模式的取景界面621。该取景界面621中全屏显示的预览图像622添加有第一美颜效果，即单个前置摄像头采集的图像继续沿用第一美颜效果。若切换后的是前后置模式，则手机100可以显示图2E中的(b)示出的取景界面203e。该取景界面203e中全屏显示的预览图像204e未添加第一美颜效果。即，关闭了美颜效果。
场景4，从采用两个后置摄像头采集图像(如后后双镜模式)切换到其它多镜子模式。
采用两个摄像头采集图像的情况下，后置摄像头不支持美颜，则后后双镜模式是不支持美颜的。因此，后后双镜模式的取景界面中的预览图像不会添加有美颜效果，在此基础上，切换到其它多镜子模式后，依然不会添加有美颜效果。
关于上述场景3和场景4，需要说明如下：
场景3可能出现在场景1的S613之后，即在从采用单个摄像头采集图像切换为采用一个前置摄像头和一个后置摄像头采集图像之后，再次切换为采用单个摄像头采集图像。针对场景3出现在场景1的S613之后的情况，则可以按照S615来处理，否则，则按照场景3中的方式来处理。从而可以保证智能设置美颜效果的一致性，避免发生冲突。
类似的，场景4可能出现在场景1的S613之后，即在从采用单个摄像头采集图像切换为采用两个后置摄像头采集图像之后，再次切换为采用单个摄像头采集图像。针对场景4出现在场景1的S613之后的情况，则可以按照S615来处理。或者，场景4可能出现在场景2的S643之后，即在从采用一个前置摄像头和一个后置摄像头采集图像切换为采用两个后置摄像头采集图像之后，再次切换为采用一个前置摄像头和一个后置摄像头采集图像。针对场景4出现在场景2的S643之后的情况，则可以按照S645来处理。否则，则按照场景4中的方式来处理。从而可以保证智能设置美颜效果的一致性，避免发生冲突。
另外，由于正在录像的过程中无法通过用户手动来设置美颜级别，采用上述智能设置美颜效果的方式，可以实现录像过程中美颜效果的自动设置。
在前述关于美颜功能的说明中，针对各种场景，仅以一次或者两次切换过程来说明了手机自动设置美颜的具体实现。实际中，两次以上的切换过程中，也可以自动设置美颜。下面以一个完整的示例来说明多次切换多镜子模式的过程中，手机自动设置美颜的具体实现。
在首次切换前，手机通过第一摄像头采集图像，并以全屏显示。其中，第一摄像头是后置摄像头。即，首次切换前，手机采用的录制模式是单后置模式。在单后置模式下，手机添加第一美颜效果后，可显示第一界面，第一界面是手机录像的取景界面，第一界面中包括全屏显示的第一预览图像，第一预览图像是对第一摄像头采集的第一图像添加第一美颜效果后得到的。例如，第一界面是图6D中的(b)示出的取景界面623。
该第一界面中还包括第一控件(如模式图标或者面板展示控件)，第一控件用于触发手机切换录制模式(即多镜子模式)。
在单后置模式下，手机可通过第一控件将录制模式切换为前后双镜模式或者画中画模式。具体的，手机可接收用户对第一界面中第一控件的点击操作。手机响应于点击操作，可在第一界面中显示多个选项(即多个模式选项)，多个选项与多种录制模式一一对应。手机可接收用户对第一选项的选择操作，第一选项是多个选项中的一个，第一选项对应前后双镜模式或者画中画模式。手机响应于该选择操作，可显示第二界面，第二界面是手机录像的取景界面，第二界面中包括第二预览图像和第三预览图像，第二预览图像是对第二摄像头采集的第二图像处理、且未添加美颜效果后得到的，第三预览图像是对第三摄像头采集的第三图像处理、且未添加美颜效果后得到的。即，手机响应于用户对第一选项的选择操作，则可切换到前后双镜模式或者画中画模式，并且切换后的取景界面中，两个预览图像均未添加美颜效果。例如，第一界面是图6D中的(b)示出的单后置模式的取景界面623，第二界面是图6E中的(b)示出的前后双镜模式的取景界面628。
在切换为前后双镜模式或者画中画模式后，手机还可以在第二界面中显示第一提示信息，第一提示信息用于提示在使用两个摄像头采集图像的情况下，所有后置摄像头采集的图像均不支持美颜。从而可以提示用户取消滤镜的原因。
在切换为前后双镜模式或者画中画模式，并取消美颜后，手机可继续切换为单前置模式或者单后置模式。具体的，第二界面中也可以包括第一控件，在显示第二界面之后，手机可接收用户对第二界面中第一控件的点击操作。手机响应于点击操作，在第二界面中显示多个选项。手机接收用户对第二选项的选择操作，第二选项是多个选项中的一个，第二选项对应单前置模式或者单后置模式。手机响应于选择操作，显示第三界面，第三界面是手机录像的取景界面，第三界面中包括全屏显示的第四预览图像，第四预览图像是对第四摄像头采集的第四图像添加第一美颜效果后得到的。第四摄像头是后置摄像头或者前置摄像头。即，手机响应于用户对第二选项的选择操作，则可切换到单前置模式或者单后置模式，并且可恢复至首次切换前的美颜效果，即第一美颜效果。例如，第二界面是图6E中的(b)示出的前后双镜模式的取景界面628，第三界面是图6D中的(a)示出的单前置模式的取景界面621。
若第四摄像头是前置摄像头，即切换到单前置模式，并美颜效果后，手机还可以继续切换为前后双镜模式或者画中画模式。具体的，第三界面中也可以包括第一控件，在显示第三界面之后，手机可接收用户对第三界面中第一控件的点击操作。手机响应于点击操作，在第三界面中显示多个选项。手机接收用户对第三选项的选择操作，第三选项对应前后双镜模式或者画中画模式。应注意，第四选项对应的录制模式和第一选项对应的录制模式可以相同，例如，均为前后双镜模式。或者，第四选项对应的录制模式和第一选项对应的录制模式也可以相同，例如，第四选项对应的录制模式为画中画模式，第一选项对应的录制模式为前后双镜模式。手机响应于选择操作，显示第四界面，第四界面是手机录像的取景界面，第四界面中包括第五预览图像和第六预览图像。第五预览图像是对第五摄像头采集的第五图像添加第一美颜效果后得到的，第五摄像头是前置摄像头。第六预览图像是对第六摄像头采集的第五图像处理、且未添加美颜效果后得到的，第六摄像头是后置摄像头。也就是说，在从单前置模式切换为前后双镜模式或者画中画模式后，前置摄像头采集的图像可以沿用切换前的第一美颜效果，而后置摄像头采集的图像则不添加美颜效果。例如，第三界面是图6D中的(a)示出的单前置模式的取景界面621，第四界面是图6E中的(a) 示出的前后双镜模式的取景界面625。
在从单前置模式切换为前后双镜模式或者画中画模式后，手机可以继续切换到后后双镜模式。具体的，录制模式还包括后后双镜模式，第四界面中也可以包括第一控件。在显示第四界面之后，手机可接收用户对第四界面中第一控件的点击操作。手机响应于点击操作，在第四界面中显示多个选项。手机可接收用户对第四选项的选择操作，第四选项是多个选项中的一个，第四选项对应后后双镜模式。手机响应于选择操作，显示第五界面，第五界面是手机录像的取景界面，第五界面中包括第七预览图像和第八预览图像。第七预览图像是对第七摄像头采集的第七图像处理、且未添加美颜效果后得到的，第八预览图像是对第八摄像头采集的第八图像处理、且未添加美颜效果后得到的。其中，第七摄像头和第八摄像头均是后置摄像头。也就是说，在从前后双镜模式或者画中画模式切换为后后双镜模式后，两个后置摄像头采集的图像均不添加美颜效果。例如，第四界面是图6E中的(a)示出的前后双镜模式的取景界面625，第五界面是图2D中的(b)示出的后后双镜模式的取景界面204d。
或者，在切换为前后双镜模式或者画中画模式，并取消美颜，而后继续切换为单前置模式或者单后置模式，并恢复美颜效果后，手机还可继续切换到后后双镜模式。具体的，录制模式还包括后后双镜模式，第三界面中还包括第一控件。在显示第三界面之后，手机接收用户对第三界面中第一控件的点击操作。手机响应于点击操作，在第三界面中显示多个选项。手机接收用户对第四选项的选择操作，第四选项是多个选项中的一个，第四选项对应后后双镜模式。手机响应于选择操作，显示第六界面，第六界面是手机录像的取景界面，第六界面中包括第九预览图像和第十预览图像。第九预览图像是对第九摄像头采集的第九图像处理、且未添加美颜效果后得到的。第十预览图像是对第十摄像头采集的第十图像处理、且未添加美颜效果后得到的。第九摄像头和第十摄像头均是后置摄像头。也就是说，在从单前置模式或者单后置模式切换为后后双镜式后，两个后置摄像头采集的图像均不添加美颜效果。例如，第三界面是图6D中的(a)示出的单前置模式的取景界面621，图2D中的(b)示出的后后双镜模式的取景界面204d。
