Description

切换摄像头的方法与电子设备
本申请要求于2022年10月24日提交国家知识产权局、申请号为202211303569.6、申请名称为“切换摄像头的方法与电子设备”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
本申请涉及终端领域，具体地，涉及一种切换摄像头的方法与电子设备。
背景技术
电子设备在拍摄时，为了采集清晰的图像，经常会面临自动切换摄像头的需求；例如，当电子设备拍摄远距离的景物时，可以切换至长焦摄像头；当电子设备拍摄近距离的景物时，可以切换至超广角摄像头。在电子设备中不包括激光传感器的情况下，电子设备可以基于广角摄像头的参数，进行不同摄像头的自动切换；例如，电子设备可以根据广角摄像头的参数识别电子设备与拍摄物体之间的距离较近时，可以自动切换至将超广角摄像头作为主摄摄像头，进入超级微距模式；但是，在电子设备与拍摄对象之间的距离较近的情况下，电子设备与拍摄对象之间的距离小于广角摄像头进行对焦的有效距离，导致广角摄像头的参数的准确性降低，使得电子设备在处于超级微距模式拍摄时可能会出现自动退出的问题，导致超级微距模式的稳定性较差。
因此，如何提高电子设备中拍摄模式(例如，超级微距模式或者超级远景模式)的稳定性成为一个亟需解决的问题。
发明内容
本申请提供了一种切换摄像头的方法与电子设备，能够提高电子设备中拍摄模式(例如，超级微距模式)的稳定性，提高用户的拍摄体验。
第一方面，提供了一种切换摄像头的方法，应用于电子设备，所述电子设备包括摄像头模组，所述摄像头模组包括第一摄像头与第二摄像头，所述方法包括：
运行所述电子设备中的相机应用程序；
显示第一图像，所述第一图像为所述第一摄像头作为主摄摄像头进行采集图像得到的；
确定第一距离与第二距离是否满足第一预设条件，其中，所述第一距离与所述第二距离用于指示所述电子设备与拍摄对象之间的物距，所述第一距离为基于所述第一摄像头的参数得到的物距，所述第二距离为基于所述第二摄像头的参数得到的物距；
在所述第一距离与所述第二距离满足所述第一预设条件的情况下，显示第二图像，所述第二图像为所述第二摄像头作为主摄摄像头进行采集图像得到的。
在本申请的实施例中，在第一距离与第二距离满足第一预设条件时，电子设备切换至将第二摄像头作为主摄摄像头，显示第二图像；由于第一距离为根据第一摄像头的参数得到的物距，第二距离为根据第二摄像头的参数得到的物距；因此，在本申请的实施例中， 在判断是否切换至第二摄像头作为主摄摄像头时，会根据双重限制条件确定是否切换摄像头；与现有的方案中，只基于第二摄像头的参数判断是否切换摄像头相比，本申请实施例提供的切换摄像头的方法的准确性更高，即电子设备中拍摄模式的稳定性更好。
结合第一方面，在第一方面的某些实现方式中，所述第一距离与第二距离满足第一预设条件，包括：
确定所述第一距离大于第一预设阈值，且所述第二距离大于第二预设阈值，其中，所述第一预设阈值与所述第二预设阈值不同。
结合第一方面，在第一方面的某些实现方式中，所述第一预设阈值为基于第一距离范围得到的预设阈值，所述第一距离范围用于表示所述第一摄像头进行对焦的有效距离范围。

结合第一方面，在第一方面的某些实现方式中，还包括：

在所述亮度参数小于或者等于所述第一亮度阈值的情况下，显示所述第二图像。
在本申请的实施例中，在第一距离和/或第二距离不满足预设条件的情况下，电子设备还可以进一步根据拍摄场景的亮度参数确定是否退出超级微距模式；由于在电子设备所处的拍摄场景较暗的情况下，第一摄像头采集的参数与第二摄像头采集的参数的准确性较低；由于第一摄像头采集的参数与第二摄像头采集的参数的准确性较低，则第一距离与第二距离的准确性较低；此时，电子设备可以直接退出超级微距模式。
结合第一方面，在第一方面的某些实现方式中，所述第一亮度阈值为基于第一亮度范围得到的预设阈值，所述第一亮度范围用于表示所述第一摄像头进行对焦的有效亮度范围。

在所述亮度参数大于所述第一亮度阈值的情况下，确定所述第二变焦倍率与所述第一变焦倍率是否相同；
在所述第二变焦倍率与所述第一变焦倍率不相同的情况下，显示所述第二图像。
在本申请的实施例中，在第一距离和/或第二距离不满足预设条件，且电子设备所处的拍摄场景的亮度参数大于第一亮度阈值的情况下，可以确定电子设备的变焦倍率是否发生变化；若电子设备的变焦倍率发生变化，则电子设备退出超级微距模式；例如，电子设备的变焦倍率发生变化，则可能是用户对电子设备的变焦倍率进行了调整；此时，电子设备退出超级微距模式。
结合第一方面，在第一方面的某些实现方式中，所述显示第一图像，包括：
在所述电子设备所处的拍摄环境的亮度参数大于第二亮度阈值，且所述第二距离小于或者等于第三预设阈值的情况下，显示所述第一图像。
在本申请的实施例中，在电子设备进入超级微距模式时，可以根据电子设备的拍摄场 景的亮度与第二距离确定电子设备是否进入超级微距模式；与基于第二距离确定电子设备是否进入超级微距模式相比，本申请实施例中进入超级微距模式的准确性更高。
结合第一方面，在第一方面的某些实现方式中，所述第二亮度阈值为基于第二亮度范围得到的预设阈值，所述第二亮度范围用于表示所述第二摄像头进行对焦的有效亮度范围。
结合第一方面，在第一方面的某些实现方式中，在所述第一摄像头包括开环马达的情况下，还包括：

具体实施方式
在本申请的实施例中，以下术语“第一”、“第二”等仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本实施例的描述中，除非另有说明，“多个”的含义是两个或两个以上。
为了便于对本申请实施例的理解，首先对本申请实施例中涉及的相关概念进行简要说明。
1、视场角(field of view，FOV)
视场角在光学工程中又称视场，视场角的大小决定了光学仪器的视野范围；电子设备 的视场角用于指示电子设备在对拍摄对象进行拍摄的过程中，摄像头所能拍摄到的最大角度。
应理解，视场角还可以被称为“视场范围”、“视野范围”、“视野区域”等。
2、距离参数
距离参数可以用于表示镜头与电子设备中传感器之间的距离信息；例如，距离参数越大，则表示镜头与传感器之间的距离越大，即可以表示电子设备与拍摄对象之间的距离越近；距离参数越小，则表示镜头与传感器之间的距离越小，即可以表示电子设备与拍摄对象之间的距离越远。应理解，距离参数可以被称为“code值”；或者，距离参数又可以被称为镜头位置(lens position)。
3、一次性编程(One Time Programmable，OTP)数据
OTP为MCU的一种存储器类型，用于表示一次性编程；多是采用融丝结构，编程过程是不可逆的破坏活动。
应理解，在本申请的实施例中，OTP数据为存储在摄像头的器件中的数据；OTP数据不会随着拍摄场景或者拍摄对象的改变而改变。
可选地，在本申请的实施例中，OTP数据中包括摄像头的code值与物距之间的映射关系；物距是指电子设备与拍摄对象之间的物距；code值用于表示电子设备中摄像头对焦时输出的马达的移动距离。
4、变焦倍率(zoom)
变焦倍率用于表示电子设备在拍摄时的变焦大小。
5、主摄摄像头与辅助摄像头
电子设备中可以包括多个摄像头；例如，多个摄像头中可以包括主摄摄像头与辅助摄像头；在电子设备采集图像时，通常以主摄摄像头采集的图像作为基准，对主摄摄像头采集的图像进行处理；在处理的过程中，可以提取辅助摄像头采集的部分图像信息对主摄摄像头采集的图像进行补偿，实现对两个摄像头采集的图像进行融合，并经过处理后得到显示的图像，来达到从而提升拍摄质量、背景虚化、光学变焦等功能。
示例性地，若电子设备采集图像时为单摄模式，即电子设备开启一个摄像头采集图像，该摄像头即为主摄摄像头。
示例性地，若电子设备采集图像时为双摄模式，即电子设备开启两个摄像头采集图像；其中，一个摄像头为主摄摄像头，另一个摄像头为辅助摄像头；在采集图像时，通常以主摄摄像头采集的图像作为基准，对主摄摄像头采集的图像进行处理；在处理过程中，可以提取部分辅助摄像头采集的部分图像信息对主摄摄像头采集的图像进行补偿，实现对两个摄像头采集的图像进行融合，并经过处理后得到显示的图像，来达到从而提升拍摄质量、背景虚化、光学变焦等功能。
在一个示例中，电子设备中的双摄可以为广角摄像头与长焦摄像头；其中，广角摄像头可以作为主摄摄像头，长焦摄像头可以作为辅助摄像头；将广角摄像头采集的图像作为基准，在对广角摄像头采集的图像进行处理的过程中，可以提取长焦摄像头采集的远处拍摄对象的图像信息，实现将广角摄像头与长焦摄像头采集的图像进行融合，通过长焦摄像头可以补充远处拍摄对象的细节信息；并经过处理后得到显示的图像，使得电子设备在拍摄时具有更远的光学变焦。

6、超级微距模式
超级微距模式是指电子设备在1倍变焦倍率(1×)至2倍变焦倍率(2×)之间，电子设备自动切换至超广角摄像头作为主摄摄像头进行拍摄的拍摄模式。
示例性地，电子设备在由远至近的拍摄场景中；例如，在电子设备的位置保持不变的情况下，第一时刻电子设备的变焦中心为第一拍摄对象；第二时刻电子设备的变焦中心为第二拍摄对象，第一拍摄对象与电子设备距离较远，第二拍摄对象与电子设备距离较近；则在电子设备在拍摄第二拍摄对象时，电子设备可以自动将超广角摄像头作为主摄摄像头，进入超级微距模式从而增大电子设备拍摄时的视场角。
例如，如图1中的(a)所示，在同一拍摄场景中包括第一拍摄对象260与第二拍摄对象270，第一拍摄对象与电子设备之间的距离为d1，第二拍摄对象与电子设备之间的距离为d2,d2小于d1；图2为该拍摄场景的侧视图，电子设备100包括摄像模组272；在拍摄过程中，电子设备保持位置不变；电子设备开启相机应用程序，在第一时刻电子设备对准第一拍摄对象260进行对焦，电子设备可以显示显示界面280；此时，电子设备的变焦倍率为1×(可以理解的，也可以为1×到2×之间的任意值，也可以为其他值，本申请实施例不进行限定)；如图1中的(b)所示，在第二时刻，电子设备保持1×(可以理解的，也可以为1×到2×之间的任意值，也可以为其他值，本申请实施例不进行限定)且改变拍摄对象；例如，电子设备对第二拍摄对象270进行对焦，此时电子设备识别到第二拍摄对象270与电子设备之间的距离较近，电子设备可以进入超级微距模式自动切换至超广角摄像头作为主摄摄像头进行对焦，显示显示界面290。

8、自动对焦系统
电子设备上拍摄装置(例如，摄像头)通常会采用自动对焦系统进行对焦。自动对焦系统主要由镜头、马达、马达驱动芯片和感光芯片构成。其中，镜头和感光芯片是成像的主要器件，马达和马达驱动芯片是自动对焦的主要器件。镜头和感光芯片之间的距离别称为焦距。拍摄对象距离摄像头的位置不同，对应的成像位置不同，需要调整镜头和感光芯片的距离(焦距)，使得感光芯片上可以获得清晰的成像。自动对焦系统通常是通过马达带动镜头移动来调整焦距的。
9、开环马达(open loop)
开环马达是指带动镜头移动的马达是根据输入的电流大小确定镜头的移动距离，在移动镜头的过程中没有反馈信号来修正所移动的距离。相当于输入开环马达的马达驱动芯片的是电流值，输出的是镜头的移动距离，马达驱动芯片不会根据镜头实际的移动距离调整输出的移动距离。因此，采用开环马达的定焦通常精度不高。
10、闭环马达(close loop)
与开环马达相比，闭环马达在镜头上加装霍尔芯片，通过霍尔芯片来感应四周磁铁的磁通量，进而推算出镜头实际的位置。闭环马达可以将镜头的实际位置作为反馈信号输入马达驱动芯片，马达驱动芯片根据该反馈信号调整输出的移动距离。也即是说，闭环马达可以将镜头实际的移动位置作为反馈信号，精确调整镜头的位置，成像质量高。

上文详细描述了电子设备100的硬件系统，下面介绍电子设备100的软件系统。
图10是本申请实施例提供的电子设备的软件系统的示意图。
如图10所示，系统架构中可以包括应用层210、应用框架层220、硬件抽象层230、驱动层240以及硬件层250。

例如，硬件抽象层230中包括相机硬件抽象层与相机算法。相机硬件抽象层可以调用相机算法；相机算法中可以包括用于图像处理的软件算法。
示例性地，相机算法库中可以包括本申请实施例提供的切换摄像头的方法对应的算法。
示例性地，相机算法中的算法可以是指不依赖特定硬件实现；比如，通常可以在CPU中运行的代码等。
驱动层240用于为不同硬件设备提供驱动。例如，驱动层可以包括摄像头驱动。
硬件层250位于操作系统的最底层；如图10所示，硬件层250可以包括摄像头1、摄像头2、摄像头3等。其中，摄像头1、摄像头2、摄像头3可对应于电子设备上的多个摄像头。
为了便于理解，下面以电子设备100为具有上述软硬件结构的手机为例，先对本申请实施例提供的切换摄像头的方法所适用的电子设备100上的摄像头和界面先进行详细描述。
本申请实施例提供的切换摄像头的方法所适用的电子设备上至少具有多个摄像头193，例如，具有3种摄像头193；该3种摄像头分别为主摄摄像头(例如，广角摄像头)、超广角摄像头与长焦摄像头；该3种摄像头可以用于拍摄同一待拍摄场景。
可选地，电子设备100上还可以具有其他摄像头193，摄像头193的种类以及每种摄像头193的个数均可以根据需要进行设置，本申请实施例对此不进行任何限制。
示例性的，如图11所示以电子设备100可以具有3个摄像头193为例进行说明；3个摄像头的排布方式可以如图11中的(a)所示，或者如图11中的(b)所示；例如，该3个摄像头193可以为主摄摄像头1931(例如，广角摄像头)、超广角摄像头1932和长焦摄像头1933。
应理解，上述仅为两种排布方式的示例，也可以为其他的排布方式；具体排布方式可以根据需要进行设计和更改，本申请实施例对此不进行任何限制。
需要说明的是，上述3个摄像头在拍摄时，通常主摄摄像头1931对应的视场角范围大于长焦摄像头1933对应的视场角范围；而超广角摄像头1932对应的视场角范围大于主摄摄像头1931对应的视场角范围；超广角摄像头1932的视场角与主摄摄像头1931的视场角之间可能存在重叠；也就是说，超广角摄像头1932可以拍摄到主摄摄像头1931拍摄的场景内容及其周边的场景内容。
应理解，长焦摄像头1933对应的视场角范围小于主摄摄像头1931对应的视场角范围，主摄摄像头1931的视场角与长焦摄像头1933的视场角之间可能存在重叠；也就是说，主摄摄像头1931可以拍摄到长焦摄像头1933拍摄的场景内容及其周边的场景内容。超广角摄像头1932的视场角与长焦摄像头1933的视场角之间可能存在重叠的；也就是说，超广角摄像头1932可以拍摄到长焦摄像头1933拍摄的场景内容及其周边的场景内容。
其中，超广角摄像头1932由于对焦距离较小，所以适合拍摄近景；并且，顾名思义，超广角摄像头1932适合拍摄视场角比较大的场景；主摄摄像头1931，由于清晰度较高，比较适合拍摄肖像，而长焦摄像头1933比较适合拍摄远景特写。
示例性地，如图12所示，超广角摄像头的变焦倍数可以小于M倍变焦倍率；广角摄 像头即主摄摄像头的变焦倍数范围可以为[M,N)；长焦摄像头的变焦倍数可以大于或者等于N倍变焦倍率。
例如，M可以为1，N可以为3.5；则超广角摄像头的变焦倍数为小于1倍变焦倍率(1×)；广角摄像头的变焦倍率范围为1倍变焦倍率至3.5倍变焦倍率[1×～3.5×)；长焦摄像头的变焦倍率为大于或者等于3.5倍变焦倍率。
应理解，在电子设备拍摄的过程中，变焦倍率越大，则对应的视场角越小。
目前，在电子设备中不包括激光传感器的情况下，电子设备可以基于广角摄像头的参数，进行不同摄像头的自动切换；例如，电子设备可以根据广角摄像头的参数识别电子设备与拍摄物体之间的距离较近时，可以自动切换至将超广角摄像头作为主摄摄像头，进入超级微距拍摄模式；但是，在电子设备与拍摄对象之间的距离较近的情况下，电子设备与拍摄对象之间的实际物距不在广角摄像头采集距离参数的有效范围内，导致广角摄像头的参数的准确性降低；使得电子设备在处于超级微距拍摄模式拍摄时容易出现自动退出超级微距拍摄模式的问题，导致超级微距拍摄模式的稳定性较差；例如，根据广角摄像头的参数映射出的有效物距范围为8cm～5m；若电子设备与拍摄对象之间的实际物距小于8cm，则基于广角摄像头采集的参数得到的电子设备与拍摄对象之间的距离不准确，或者，不稳定；因此，在电子设备与拍摄对象距离较近时，广角摄像头采集的参数可能存在误差，使得电子设备在处于超级微距拍摄模式拍摄时容易出现自动退出超级微距拍摄模式的问题；如图13中的(a)所示，电子设备处于超级微距模式；若拍摄对象移动至与电子设备更近的距离，由于广角摄像头采集的参数存在一定的误差，导致电子设备可能出现闪退现象；如图13中的(b)所示，电子设备可能自动退出超级微距模式。
有鉴于此，本申请实施例提供了一种切换摄像头的方法与电子设备，该方法应用于电子设备，电子设备包括摄像头模组，摄像头模组包括第一摄像头(例如，超广角摄像头)与第二摄像头(例如，广角摄像头)，方法包括：运行电子设备中的相机应用程序；显示第一图像，第一图像为第一摄像头作为主摄摄像头进行采集图像得到的；确定第一距离与第二距离是否满足第一预设条件，其中，第一距离与第二距离用于指示电子设备与拍摄对象之间的物距，第一距离为基于第一摄像头的参数得到的物距，第二距离为基于第二摄像头的参数得到的物距；在第一距离与第二距离满足第一预设条件的情况下，显示第二图像，第二图像为第二摄像头作为主摄摄像头进行采集图像得到的。在本申请的实施例中，在第一距离与第二距离满足第一预设条件时，电子设备切换至将第二摄像头作为主摄摄像头；由于第一距离为根据第一摄像头的参数得到的物距，第二距离为根据第二摄像头的参数得到的物距；因此，在本申请的实施例中，在判断是否切换至第二摄像头作为主摄摄像头时，会根据双重限制条件确定是否切换摄像头；与现有的方案中，只基于第二摄像头的参数判断是否切换摄像头相比，本申请实施例提供的切换摄像头的方法的稳定性更高。

示例性地，本申请实施例中的切换摄像头的方法还可以应用于录制视频的场景，或者，视频通话场景中，其中，视频通话场景可以包括但不限于以下场景中：

在本申请的实施例中，在电子设备进入超级微距模式时，可以根据电子设备的拍摄场景的亮度与第二距离确定电子设备是否进入超级微距模式；与基于第一距离确定电子设备是否进入超级微距模式相比，本申请实施例中进入超级微距模式的准确性更高。
可选地，第二亮度阈值为基于第二亮度范围得到的预设阈值，第二亮度范围用于表示第二摄像头进行对焦的有效亮度范围。
例如，第二摄像头进行有效对焦的亮度范围为[L1,L2]，则第二亮度阈值大于或者等于L1。
步骤S330、确定第一距离与第二距离是否满足第一预设条件。
其中，第一距离与第二距离用于指示电子设备与拍摄对象之间的物距，第一距离为基于第一摄像头的参数得到的物距，第二距离为基于第二摄像头的参数得到的物距。

在本申请的实施例中，在电子设备的第一摄像头(例如，超广角摄像头)包括开环马达的情况下，可以对第一摄像头的参数进行补偿处理；例如，可以对超广角摄像头输出的code值进行补偿处理，使得code值的准确性跟高；在code值准确性更高的情况下，得到的电子设备与拍摄对象之间的第一距离更准确。
步骤S340、在第一距离与第二距离满足第一预设条件的情况下，显示第二图像。
其中，第二图像为第二摄像头作为主摄摄像头进行采集图像得到的。
在本申请的实施例中，在第一距离与第二距离满足预设条件的情况下，电子设备会将第二摄像头作为主摄摄像头显示第二图像；由于第一距离为根据第一摄像头的参数得到的物距，第二距离为根据第二摄像头的参数得到的物距；因此，在本申请的实施例中，在判断是否切换至第二摄像头作为主摄摄像头时，会根据双重限制条件确定是否切换摄像头；与现有的方案中，只基于第二摄像头的参数判断是否切换摄像头相比，本申请实施例提供的切换摄像头的方法的稳定性更高。
示例性地，在电子设备处于超级微距模式的情况下，电子设备可以将超广角摄像头(第一摄像头的一个示例)作为主摄摄像头显示第一图像；在电子设备确定基于超广角摄像头的参数得到的电子设备与拍摄对象之间的第一距离，与基于广角摄像头(第二摄像头的一个示例)的参数得到的电子设备与拍摄对象之间的第二距离满足预设条件的情况下，电子设备退出超级微距模式；例如，电子设备根据第一距离与第二距离确定电子设备与拍摄对象之间的距离较远时，电子设备退出超级微距模式；若根据第一距离和/或第二距离不满足预设条件，则电子设备保持超级微距模式；在本申请的实施例中，电子设备可以基于超广角摄像头的参数与广角摄像头的参数确定是否退出超级微距模式，在一定程度上能够避免在广角摄像头采集的参数存在一定的误差，导致电子设备可能出现超级微距模式的闪退现象；从而提高超级微距模式的稳定性，即提 高电子设备切换摄像头的稳定性。

在第一距离和/或所述第二距离不满足第一预设条件的情况下，确定电子设备所处拍摄场景的亮度参数是否小于或者等于第一亮度阈值；在亮度参数小于或者等于第一亮度阈值的情况下，显示第二图像。
在本申请的实施例中，在第一距离和/或第二距离不满足预设条件的情况下，电子设备还可以进一步根据拍摄场景的亮度参数确定是否退出超级微距模式；由于在电子设备所处的拍摄场景较暗的情况下，第一摄像头采集的参数与第二摄像头采集的参数的准确性较低；由于第一摄像头采集的参数与第二摄像头采集的参数的准确性较低，则第一距离与第二距离的准确性较低；此时，电子设备可以直接退出超级微距模式。
可选地，第一亮度阈值为基于第一亮度范围得到的预设阈值，第一亮度范围用于表示第一摄像头进行对焦的有效亮度范围。
示例性地，第一亮度阈值位于第一摄像头进行对焦的有效亮度范围。

在亮度参数大于第一亮度阈值的情况下，确定第二变焦倍率与第一变焦倍率是否相同；在第二变焦倍率与第一变焦倍率不相同的情况下，显示第二图像。
在本申请的实施例中，在第一距离和/或第二距离不满足预设条件，且电子设备所处的拍摄场景的亮度参数大于第一亮度阈值的情况下，可以确定电子设备的变焦倍率是否发生变化；若电子设备的变焦倍率发生变化，则电子设备退出超级微距模式；例如，电子设备的变焦倍率发生变化，则可能是用户对电子设备的变焦倍率进行了调整；此时，电子设备退出超级微距模式。
可选地，第一摄像头包括超广角摄像头或者长焦摄像头，和/或，第二摄像头包括广角摄像头。
在一个示例中，第一摄像头为超广角摄像头，第二摄像头为广角摄像头；在电子设备处于超级微距模式，以超广角摄像头作为主摄摄像头，电子设备显示第一图像；在电子设备退出超级微距模式，以广角摄像头作为主摄摄像头，电子设备显示第二图像。

可选地，电子设备在显示所述第一图像与显示第二图像时，电子设备所处的位置相同。
示例性地，如图1中的(a)与图1中的(b)所示的场景，此处不再赘述。
在本申请的实施例中，在拍摄过程中电子设备的位置可以始终未改变，若电子设备的对焦对象从远景拍摄对象移动至近景拍摄对象，电子设备可以自动识别电子设备与拍摄对象之间的距离，进入超级微距模式；若电子设备的对焦对象从近景拍摄对象移动至远景拍摄对象，电子设备可以自动识别电子设备与拍摄对象之间的距离，退出超级微距模式；电子设备可以实现自动切换不同类型的摄像头作为主摄摄像头，从而确保采集图像的图像质量。
可选地，第一图像中包括第一拍摄对象，第二图像中包括第二拍摄对象，第一拍摄对 象与第二拍摄对象所处的位置相同，第一拍摄对象与电子设备之间的距离为第三距离，第二拍摄对象与电子设备之间的距离为第四距离，第三距离小于第四距离。
在本申请的实施例中，在拍摄过程中电子设备的位置可以发生改变；比如，电子设备可以移动着拍摄不同拍摄对象(例如，第一拍摄对象与第二拍摄对象)；在电子设备的对焦对象从近景拍摄对象移动至远景拍摄对象，电子设备可以自动识别电子设备与拍摄对象之间的距离，退出超级微距模式；电子设备可以实现自动切换不同类型的摄像头作为主摄摄像头，从而确保采集图像的图像质量。
可选地，第一图像与第二图像中包括第三拍摄对象，在显示第一图像与第二图像时，第三拍摄对象所处的位置相同；在采集第一图像时，第三拍摄对象与电子设备之间的距离为第五距离；在采集第二图像时，第三拍摄对象与电子设备之间的距离为第六距离，第五距离小于第六距离。
在本申请的实施例中，在拍摄过程中电子设备的位置可以发生改变；比如，电子设备可以移动着拍摄同一拍摄对象(例如，第三拍摄对象)；在电子设备的对焦对象从近景拍摄对象移动至远景拍摄对象，电子设备可以自动识别电子设备与拍摄对象之间的距离，退出超级微距模式；电子设备可以实现自动切换不同类型的摄像头作为主摄摄像头，从而确保采集图像的图像质量。
在本申请的实施例中，在第一距离与第二距离满足第一预设条件时，电子设备切换至将第二摄像头作为主摄摄像头，显示第二图像；由于第一距离为根据第一摄像头的参数得到的物距，第二距离为根据第二摄像头的参数得到的物距；因此，在本申请的实施例中，在判断是否切换至第二摄像头作为主摄摄像头时，会根据双重限制条件确定是否切换摄像头；与现有的方案中，只基于第二摄像头的参数判断是否切换摄像头相比，本申请实施例提供的切换摄像头的方法的准确性更高，即电子设备中拍摄模式的稳定性更好。
图15是本申请实施例提供的切换摄像头的方法的示意性流程图。该方法可以由图9所示的电子设备执行；该方法400包括步骤S410至步骤S444，下面分别对步骤S410至步骤S444进行详细的描述。
步骤S410、运行相机应用程序。
示例性地，用户可以通过单击“相机”应用程序的图标，指示电子设备运行相机应用。或者，电子设备处于锁屏状态时，用户可以通过在电子设备的显示屏上向右滑动的手势，指示电子设备运行相机应用程序。又或者，电子设备处于锁屏状态，锁屏界面上包括相机应用程序的图标，用户通过点击相机应用程序的图标，指示电子设备运行相机应用程序。又或者，电子设备在运行其他应用时，该应用具有调用相机应用程序的权限；用户通过点击相应的控件可以指示电子设备运行相机应用程序。例如，电子设备正在运行即时通信类应用程序时，用户可以通过选择相机功能的控件，指示电子设备开启相机应用程序等。
应理解，上述为对运行相机应用程序的操作的举例说明；还可以通过语音指示操作，或者其它操作的指示电子设备运行相机应用程序；本申请对此不作任何限定。
步骤S420、判断电子设备是否处于超级微距模式；若电子设备处于超级微距模式，则执行步骤S430；若电子设备不处于超级微距模式，则执行步骤S440。
应理解，超级微距模式可以是电子设备的一种拍摄模式；超级微距拍摄模式是指 电子设备在1倍变焦倍率(1×)至2倍变焦倍率(2×)之间，电子设备自动切换至超广角摄像头作为主摄摄像头进行拍摄的拍摄模式。
可选地，可以获取电子设备当前拍摄模式的标签，根据拍摄模式的标签确定电子设备是否处于超级微距模式。
示例性地，非超级微距模式对应的标签可以为flag＝1，超级微距模式对应的标签可以为flag＝0，在电子设备切换至超广角摄像头作为主摄摄像头后，可以将拍摄模式对应的标签更新为flag＝0。
步骤S430、获取超广角摄像头与广角摄像头的数据。
应理解，在超级微距模式下超广角摄像头作为主摄摄像头进行拍摄；此时，广角摄像头也可以处于运行状态，但广角摄像头采集的数据不用于送显。
可选地，超广角摄像头的数据可以包括函数关系1与code值；其中，函数关系1用于表示参数1(物距2)与参数2(超广角摄像头采集的code值)之间的映射关系。
可选地，可以获取超广角摄像头的OTP数据，OTP数据为存储在超广角摄像头器件中的数据，OTP数据包括函数关系1；例如，函数关系1如图16所示；图16为距离(物距)与code值之间的曲线关系的示意图。
可选地，广角摄像头的数据可以包括函数关系2与code值；其中，函数关系2用于表示参数3(物距1)与参数4(广角摄像头采集的code值)之间的映射关系。
可选地，可以获取超广角摄像头的OTP数据，超广角摄像头的OTP数据为存储在超广角摄像头器件中的数据，OTP数据包括函数关系1。
可选地，可以获取广角摄像头的OTP数据，广角摄像头的OTP数据为存储在广角摄像头器件中的数据，OTP数据包括函数关系1。
可选地，在本申请的实施例中，code值可以包括音圈马达(Voice Coil Motor，VCM)code值。
应理解，OTP数据为一种存储器类型的数据，即存储在器件中无法改变的数据。
步骤S431、判断超广角摄像头是否包括开环马达；若超广角摄像头包括开环马达，则执行步骤S432；若超广角摄像头不包括开环马达，则执行步骤S434。
应理解，由于开环马达中的驱动芯片不会根据镜头实际的移动距离调整输出的移动距离；因此，开环马达输出的镜头的移动距离的准确性较低；在镜头的移动距离的准确性较低的情况下，得到的电子设备与拍摄对象之间的物距地准确性也较低；在本申请的实施例中，若摄像头包括开环马达，则可以对开环马达输出的镜头距离进行修正，即执行步骤S442；提高电子设备与拍摄对象之间物距地准确性。
步骤S432、对超广角摄像头的code值进行补偿处理。
示例性地，如图17中的(a)所示，摄像头中的镜头处于向上位姿；如图17中的(b)所示，摄像头中的镜头处于水平位姿；如图17中的(c)所示，摄像头中的镜头处于向下位姿；例如，对于电子设备与拍摄对象之间的同一物距，按理来说图17中的(a)、图17中的(b)与图17中的(c)中镜头移动的距离相同；但是，由于重力作用，使得在相同物距的情况下，镜头的水平位姿与向上位姿，或者向下位姿之间存在差异，如图18所示。因此，在摄像头包括开环马达的情况下，可以根据摄像头的不同位姿对摄像头的参数进行补偿处理。
示例性地，图17中所示的F1用于表示电磁力；F2用于表示重力；F3用于表示弹片作用力；对于如图17中的(a)所示位姿的摄像头，NBI1L＝K*X1+mg；对于如图17中的(b)所示位姿的摄像头，NBI2L＝K*X2；对于如图17中的(c)所示位姿的摄像头，NBI3L＝K*X3-mg；取I1＝I2＝I3，X2-X1＝X3-X2＝mg/K；即表示对于不同位姿的摄像头，在电流相同时摄像头的行程(例如，移动距离)存在差异值；如图18所示，对于同一电流，若摄像头处于水平位姿则对应曲线中的B点；若摄像头处于向下位姿，则对应曲线中的C点；若摄像头处于向上位姿，则对应曲线中的A点。
例如，若摄像头的位置如图17中的(a)所示，则对摄像头输出的镜头移动距离叠加一个正补偿值；若摄像头的位置如图17中的(b)所示，则对摄像头输出的镜头移动距离叠加一个负补偿值；其中，该正补偿值或者负补偿值，可以通过预先对同一摄像头进行不同物距的数据标定，得到多组预选标定的补偿值；在实际拍摄过程中，可以根据摄像头的位置(例如，摄像头朝上或者摄像头朝下)，对超广角摄像头输出的镜头移动距离即code值进行补偿处理。
在一个示例中，标定数据中包括Δ1与Δ2；其中，Δ1用于在同一物距下，镜头处于水平与镜头处于朝上位置时，镜头移动处理的差值；Δ2用于在同一物距下，镜头处于水平与镜头处于朝下位置时，镜头移动处理的差值；若当前拍摄时，电子设备的镜头处于朝上位置，则通过Δ1对code值进行补偿；若当前拍摄时，电子设备的镜头处于朝下位置，则通过Δ2对code值进行补偿；其中，Δ1为正数，Δ2可以为负数。
步骤S433、根据补偿处理后的code值与函数关系1，得到电子设备与拍摄对象之间的物距2。
在本申请的实施例中，在电子设备的超广角摄像头包括开环马达的情况下，可以对超广角摄像头的参数进行补偿处理；例如，可以对超广角摄像头输出的code值进行补偿处理，使得code值的准确性跟高；在code值准确性更高的情况下，得到的电子设备与拍摄对象之间的物距2更准确。
可选地，在超广角摄像头包括开环马达的情况下，可以根据以下公式对超广角摄像头的code值进行补偿处理：
其中，code2表示补偿处理后的code值；code1表示超广角摄像头的code值；cosθ用于确定摄像头的位姿；x用于表示标定值；gx表示重力传感器在x轴的数据；gy表示重力传感器在y轴的数据；gz表示重力传感器在z轴的数据。
示例性地，x可以表示Lens Sag Compensation(镜头姿势差补偿)；Lens Sag Compensation是指器件在竖直向上和竖直向下时，与水平方向的Code的差值；若gz<0，使用竖直向上的Lens Sag Compensation；即使用正补偿值进行补偿；若gz≥0，使用竖直向下的Lens Sag Compensation；即使用负补偿值进行补偿。
例如，cosθ大于0表示摄像头处于向上位姿；cosθ小于0表示摄像头处于向下位姿。
步骤S434、在超广角摄像头不包括开环马达的情况下，根据code值与函数关系1，得到电子设备与拍摄对象之间的物距2。
示例性地，在超广角摄像头包括闭环马达的情况下，无需对超广角摄像头的code值进行补偿处理；可以根据超广角摄像头的code值与函数关系1，直接得到电子设备与拍摄对象之间的物距2。
需要说明的是，闭环马达可以将镜头的实际位置作为反馈信号输入马达驱动芯片，马达驱动芯片根据该反馈信号调整输出的移动距离。也就是说，闭环马达可以将镜头实际的移动位置作为反馈信号，精确调整镜头的位置；因此，在超广角摄像头包括闭环马达的情况下，超广角摄像头的code值的准确性较高，无需对超广角摄像头的code值进行补偿处理。
步骤S435、判断物距1是否满足第一预设阈值，且物距2是否满足第二预设阈值；若物距1满足第一预设阈值，且物距2满足第二预设阈值，则执行步骤S436；若物距1不满足第一预设阈值，和/或，物距2不满足第二预设阈值，则执行步骤S437。
可选地，第一预设阈值可以为广角摄像头对应的阈值；第二预设阈值可以为超广角摄像头对应的阈值。
示例性地，物距1是否满足第一预设阈值，且物距2是否满足第二预设阈值可以是指物距1大于第一预设阈值，且物距2大于第二预设阈值。
步骤S436、退出超级微距模式。
应理解，退出超级微距模式可以是指将超广角作为主摄摄像头切换为其他摄像头作为主摄摄像头。
示例性地，在物距1满足第一预设阈值，且物距2满足第二预设阈值的情况下，电子设备可以退出超级微距模式；例如，在物距1大于第一预设阈值，且物距2大于第二预设阈值的情况下，退出超级微距模式。
需要说明的是，由于在电子设备与拍摄对象之间的物距较近时，获取的广角摄像头的code值的准确度降低；因此，在本申请的实施例中，为了避免根据广角摄像头的code值判断是否退出超级微距模式导致出现闪退问题，在判断是否退出超级微距模式时，采用与广角摄像头相关的第一预设阈值，和与超广角摄像头相关的第二预设阈值同时进行判断，从而进一步提高退出超级微距的准确性；避免出现超级微距模式的闪退问题，提高超级微距模式的稳定性与鲁棒性。
可选地，可以基于一帧图像判断是否退出超级微距模式；例如，对于一帧图像，若物距1满足第一预设阈值，且物距2满足第二预设阈值，则电子设备切换摄像头退出超级微距模式。
可选地，为了确保电子设备采集图像的稳定性，电子设备在切换摄像头之前，可以基于多帧图像进行判断；例如，可以判断对于至少连续两帧图像是否物距1满足第一预设阈值，且物距2满足第二预设阈值；若对于至少连续两帧图像物距1满足第一预设阈值，且物距2满足第二预设阈值，则电子设备切换摄像头退出超级微距模式。
在本申请的实施例中，通过第一预设阈值与第二预设阈值，为了更加准确地判断电子设备与拍摄对象之间的物距较远；在电子设备与拍摄对象之间的物距较远的情况下，电子设备可以退出超级微距模式；由于在本申请的实施例中，在退出超级微距模式时，采用了第一预设阈值与第二预设阈值双重阈值；其中，第一预设阈值为广角摄像头的阈值，第二预设阈值为超广角摄像头的阈值；通过两个预设阈值判断是否退出 超级微距模式，与采用广角摄像头的单个预设阈值确定是否退出超级微距模式相比；在本申请的实施例中，超级微距模式的稳定性更好。
可选地，在电子设备退出超级微距模式之后，电子设备可以根据如图15所示的步骤S440至步骤S444确定是否再次运行超级微距模式。
步骤S437、保持超级微距模式。
示例性地，在物距1不满足第一预设阈值，和/或，物距2不满足第二预设阈值的情况下，电子设备可以保持超级微距模式；例如，在物距1小于或者等于第一预设阈值，和/或，物距2小于或者等于第二预设阈值时，电子设备保持超级微距模式。
应理解，保持超级微距模式可以是不退出超级微距模式。
步骤S440、获取广角摄像头的数据。
可选地，广角摄像头的数据可以包括函数关系2与code值；其中，函数关系2用于表示参数3(物距1)与参数4(广角摄像头采集的code值)之间的映射关系。
可选地，可以获取广角摄像头的OTP数据，广角摄像头的OTP数据为存储在广角摄像头器件中的数据，OTP数据包括函数关系2。
应理解，OTP数据为一种存储器类型的数据，即存储在器件中无法改变的数据。
步骤S441、根据广角摄像头的code值与函数关系2，得到电子设备与拍摄对象之间的物距1。
示例性地，根据广角摄像头的code值与函数关系2，可以确定code值对应的物距1。
步骤S442、判断物距1是否满足第三预设阈值；若物距1满足第三预设阈值，则执行步骤S443；若物距1不满足第三预设阈值，则执行步骤S444。
可选地，第三预设阈值可以为10厘米。例如，物距1满足第三预设阈值可以是指物距1大于第三预设阈值，物距1不满足预设阈值可以是指物距1小于或者等于第三预设阈值。
在本申请的实施例中，由于电子设备中不包括激光传感器，因此无法通过激光传感器获取电子设备与拍摄对象之间的距离信息；通过获取广角摄像头的code值，得到电子设备与拍摄对象之间的物距1；基于电子设备与拍摄对象之间的物距1可以进行判断是否对电子设备的摄像头进行切换；例如，若电子设备与拍摄对象之间的距离较近，则电子设备可以将超广角摄像头作为主摄摄像头。
可选地，在本申请的实施例中，在电子设备判断是否运行超级微距模式时，电子设备可以根据物距1与拍摄场景的亮度值；若物距1大于第三预设阈值，且拍摄场景的亮度值大于预设亮度阈值，则可以执行步骤S443；若物距1小于或者等于第三预设阈值，和/或，拍摄场景的亮度值小于或者等于预设亮度值，则执行步骤S444。
在本申请的实施例中，电子设备在确定是否运行超级微距模式时，还可以根据拍摄场景的亮度值确定是否运行超级微距模式；在较暗拍摄场景中，对焦的准确性较低即广角摄像头的code值的准确性较低，此时可以确定不运行超级微距模式；从而能够提高运行超级微距模式的准确性。
可选地，在本申请的实施例中，在电子设备判断是否运行超级微距模式时，电子设备可以根据物距1与拍摄场景的亮度值；若物距1大于第三预设阈值，且拍摄场景 的亮度值大于预设亮度阈值，且当前的变焦倍率为1倍变焦倍率，则可以执行步骤S443；若物距1小于或者等于第三预设阈值，和/或，拍摄场景的亮度值小于或者等于预设亮度值，和/或，当前的变焦倍率不是1倍变焦倍率，则执行步骤S444。具体实现方式，参见图19所示的步骤S552。
步骤S443、运行超级微距模式。
示例性地，在物距1满足第三预设阈值的情况下，运行超级微距模式。
应理解，超级微距模式是指电子设备在1倍变焦倍率(1×)至2倍变焦倍率(2×)之间，电子设备自动切换至超广角摄像头作为主摄摄像头进行拍摄的拍摄模式。
示例性地，在电子设备在未检测到用户的操作的情况下，电子设备可以从广角摄像头作为主摄摄像头切换至超广角摄像头作为主摄摄像头；换而言之，电子设备可以在未检测到任何操作的情况下，自动将超广角摄像头作为主摄摄像头。
应理解，电子设备中可以包括多个摄像头；例如，多个摄像头中可以包括主摄摄像头与辅助摄像头；在电子设备采集图像时，通常以主摄摄像头采集的图像作为基准，对主摄摄像头采集的图像进行处理；在处理的过程中，可以提取辅助摄像头采集的部分图像信息对主摄摄像头采集的图像进行补偿，实现对两个摄像头采集的图像进行融合，并经过处理后得到显示的图像，来达到从而提升拍摄质量、背景虚化、光学变焦等功能。示例性地，若电子设备采集图像时为单摄模式，即电子设备开启一个摄像头采集图像，该摄像头即为主摄摄像头。
示例性地，若电子设备采集图像时为双摄模式，即电子设备开启两个摄像头采集图像；其中，一个摄像头为主摄摄像头，另一个摄像头为辅助摄像头；在采集图像时，通常以主摄摄像头采集的图像作为基准，对主摄摄像头采集的图像进行处理；在处理过程中，可以提取部分辅助摄像头采集的部分图像信息对主摄摄像头采集的图像进行补偿，实现对两个摄像头采集的图像进行融合，并经过处理后得到显示的图像，来达到从而提升拍摄质量、背景虚化、光学变焦等功能。
示例性地，若电子设备采集图像时为多摄模式，例如电子设备采集图像时为三摄模式，则电子设备采集图像时可以开启三个摄像头；三个摄像头中包括一个主摄摄像头与两个辅助摄像头；在采集图像时，通常以主摄摄像头采集的图像作为基准，对主摄摄像头采集的图像进行处理；在处理过程中，可以提取两个辅助摄像头采集的部分图像信息对主摄摄像头采集的图像进行补偿，实现对三个摄像头采集的图像进行融合，并经过处理后得到显示的图像，来达到从而提升拍摄质量、背景虚化、光学变焦等功能。
情况1
若电子设备为单摄模式，则电子设备可以关闭广角摄像头；开启超广角摄像头，将超广角摄像头作为主摄摄像头。
情况2
若电子设备为多摄模式(例如，包括双摄模式或者三摄模式)，则电子设备可以将超广角摄像头作为主摄摄像头，辅助摄像头可以全部或者部分开启。
可选地，在电子设备运行超级微距模式之后，可以根据如图15所示的步骤S430至步骤S437确定是否退出超级微距模式。
步骤S444、不运行超级微距模式。
可选地，不运行超级微距模式可以包括电子设备继续运行当前的拍摄模式且不进入超级微距模式。
在本申请的实施例中，在物距1满足第一预设阈值且物距2满足第二预设阈值时，电子设备切换至将广角摄像头作为主摄摄像头，退出超级微距模式；由于物距2为根据超广角摄像头的参数得到的物距，物距1为根据广角摄像头的参数得到的物距；因此，在本申请的实施例中，在判断是否退出超级微距模式时，会根据双重限制条件确定是否切换摄像头；与现有的方案中，只基于广角摄像头的参数判断是否切换摄像头相比，本申请实施例提供的切换摄像头的方法的准确性更高，即电子设备中拍摄模式的稳定性更好。
应理解，上述步骤S401至步骤S444是以广角摄像头与超广角摄像头之间的切换为例进行描述；步骤S401至步骤S444还可以适用于其他类型的摄像头之间的切换，本申请对摄像头的类型不作任何限定。可选地，步骤S401至步骤S444还可以适用于广角摄像头与长焦摄像头之间的切换，即如图15所示的方法也可以适用于运行超级远景模式、退出超级远景模式或者保持超级远景模式，此处不再赘述。
例如，对于广角摄像头与长焦摄像头之间的切换，上述图15所示的步骤S420中的“是否处于超级微距模式”可以更改为“判断是否处于超级远景模式”，超级远景模式的显示界面可以如后续图25中的(b)所示；步骤S442中的“物距1是否满足第六预设阈值”可以更改为“物距1是否满足第四预设阈值”；步骤S443中的“运行超级微距模式”可以更改为“运行超级远景模式”；步骤S444中的“不运行超级微距模式”可以更改为“不运行超级远景模式”；步骤S430中的“获取广角摄像头与超广角摄像头的数据”可以更改为“获取广角摄像头和长焦摄像头的数据”；步骤S435中的“物距1满足第一预设阈值，且物距2满足第二预设阈值”可以更改为“物距1满足第四预设阈值，且物距2满足第五预设阈值”；步骤S436中的“退出超级微距模式”可以更改为“退出超级远景模式”；步骤S437中的“保持超级微距模式”更改为“保持超级远景模式”。
其中，超级远景模式是指电子设备自动切换将长焦摄像作为主摄摄像头采集图像的拍摄模式；第四预设阈值与第五预设阈值用于判断电子设备与拍摄对象之间的物距是否较近，从而确定退出超级远景模式，或者，保持超级远景模式；第四预设阈值与第一预设阈值可以不相等；同理，第五预设范围与第二预设范围不相等。此外，第三预设阈值与第六预设阈值不相等，基于物距1与第六预设阈值可以确定是否将长焦摄像头作为主摄摄像头；例如，若物距1值大于第六预设阈值，则电子设备可以从将长焦摄像头作为主摄摄像头切换到将广角摄像头作为主摄摄像头采集图像。
应理解，超级微距模式适用于近景拍摄；超级远景模式适用于远景拍摄；基于本申请实施例的切换摄像头的方法，能够避免在电子设备处于超级微距模式时，由于电子设备与拍摄对象之间的物距较近，使得电子设备出现超级微距模式闪退问题；或者，避免在电子设备处于超级远景模式时，由于电子设备与拍摄对象之间的物距较远，使得电子设备出现超级远景模式闪退问题；提升超级微距模式或者超级远景模式的稳定性。
可选地，在本申请的实施例中，还可以根据拍摄场景的亮度值和/或电子设备当前 的变焦倍率确定是否退出超级微距模式；从而进一步提高超级微距模式的稳定性。
在一个示例中，在物距1不满足第一预设阈值，和/或，物距2不满足第二预设阈值的情况下，可以根据拍摄场景的亮度值和电子设备当前的变焦倍率确定是否退出超级微距模式，如图19所示。
图19是本申请实施例提供的切换摄像头的方法的示意性流程图。该方法可以由图9所示的电子设备执行；该方法500包括步骤S510至步骤S554，下面分别对步骤S410至步骤S554进行详细的描述。
步骤S510、运行相机应用程序。
步骤S520、判断是否处于超级微距模式；若电子设备处于超级微距模式，则执行步骤S530；若电子设备不处于超级微距模式，则执行步骤S550。
步骤S530、获取超广角摄像头的数据。
步骤S531、判断超广角摄像头是否包括开环马达；若超广角摄像头包括开环马达，则执行步骤S532；若超广角摄像头不包括开环马达，则执行步骤S534。
步骤S533、根据补偿处理后的code值与函数关系1，得到电子设备与拍摄对象之间的物距2。
步骤S534、在超广角摄像头不包括开环马达的情况下，根据code值与函数关系1，得到电子设备与拍摄对象之间的物距2。
步骤S535、判断物距1是否满足第一预设阈值，且物距2是否满足第二预设阈值；若物距1满足第一预设阈值，且物距2满足第二预设阈值，则执行步骤S536；若物距1不满足第一预设阈值，和/或，物距2不满足第二预设阈值，则执行步骤S537。
步骤536、退出超级微距模式。
步骤S537、判断亮度参数是否小于或者等于亮度阈值1。若亮度参数小于或者等于亮度阈值1，则执行步骤538；若亮度阈值大于亮度阈值1，则执行步骤S539。
在本申请的实施例中，在电子设备处于超级微距模式的情况下，在判断是否需要退出超级微距模式时，可以根据电子设备所处拍摄场景的亮度参数进行判断；若电子设备所处的拍摄场景的亮度值较低，即拍摄场景的亮度参数小于或者等于亮度阈值1，由于在亮度较低的拍摄场景中超广角摄像头的参数与广角摄像头的参数的准确性较低，因此可以直接退出超级微距模式。
可选地，在电子设备处于超级微距模式时，电子设备中的超广角摄像头为主摄摄像头，此时的亮度阈值1可以为超广角摄像头对应的亮度阈值。
步骤S538、退出超级微距模式。
示例性地，在亮度参数小于或者等于亮度阈值1的情况下，退出超级微距模式。
步骤S539、判断变焦倍率是否变化；若变焦倍率变化，则执行步骤S540；若变焦倍率未改变，则执行中不S541。
可选地，在电子设备运行超级微距模式时，变焦倍率为第一变焦倍率；电子设备的当前变焦倍率为第二变焦倍率；若第二变焦倍率与第一变焦倍率不同，则表示电子设备的变焦倍率变化，则执行步骤S540；若第二变焦倍率与第一变焦倍率相同，则表示电子设备的变焦倍率未发生变化，则执行步骤S541。
可选地，在电子设备检测到调整变焦倍率的操作，则执行步骤S540；若电子设备 未检测到调整变焦倍率的操作，则执行步骤S541。
在本申请的实施例中，在电子设备运行超级微距模式的情况下，可以根据电子设备当前的变焦倍率确定是否退出超级微距模式；从能够进一步增加超级微距模式的稳定性。
步骤S540、退出超级微距模式。
可选地，在电子设备的变焦倍率大于1倍变焦倍率的情况下，可以退出超级微距模式。
示例性地，若电子设备检测到用户调整变焦倍率的操作(例如，倍率调整至大于1倍变焦)；响应于用户的操作，电子设备可以退出超级微距模式。
步骤S541、保持超级微距模式。
步骤S550、获取广角摄像头的数据。
步骤S551、根据广角摄像头的code值与函数关系2，得到电子设备与拍摄对象之间的物距1。
步骤S552、判断亮度参数是否满足亮度阈值2，且变焦倍率是否等于倍率1，且物距1是否满足第三预设阈值；若是，则执行步骤S553；若否，则执行步骤S554。
应理解，由于步骤S550至步骤S562是在电子设备未处于超级微距模式的情况下执行的步骤，因此，步骤S562中的亮度阈值2是与广角摄像头相关的亮度阈值。
可选地，亮度参数满足亮度阈值2可以是指亮度参数大于亮度阈值2；物距1满足第三预设阈值可以是指物距1小于或者等于第三预设阈值。
可选地，亮度参数可以包括照度值，或者，亮度值。
可选地，在本申请的实施例中，在运行超级微距模式的情况下，可以通过超广角摄像头获取照度值(例如，Lux index)；若照度值大于亮度阈值2时，则表示电子设备所处的拍摄环境为低亮拍摄环境。
应理解，通常情况下照度值越大，表示拍摄环境的亮度越低。
可选地，在本申请的实施例中，可以获取电子设备的亮度值；若亮度值小于亮度阈值2的情况下，则表示电子设备所处的拍摄环境为夜景拍摄环境。
例如，亮度值的具体计算公式如下：
其中，Exposure为曝光时间；Aperture为光圈大小；Iso为感光度；Luma为图像在XYZ颜色空间中，Y的平均值。
步骤S553、运行超级微距模式。
示例性地，在物距1满足第三预设阈值的情况下，运行超级微距模式。
应理解，超级微距模式是指电子设备在1倍变焦倍率(1×)至2倍变焦倍率(2×)之间，电子设备自动切换至超广角摄像头作为主摄摄像头进行拍摄的拍摄模式。
示例性地，在电子设备在未检测到用户的操作的情况下，电子设备可以从广角摄像头作为主摄摄像头切换至超广角摄像头作为主摄摄像头；换而言之，电子设备可以在未检测到任何操作的情况下，自动将超广角摄像头作为主摄摄像头。
应理解，电子设备中可以包括多个摄像头；例如，多个摄像头中可以包括主摄摄 像头与辅助摄像头；在电子设备采集图像时，通常以主摄摄像头采集的图像作为基准，对主摄摄像头采集的图像进行处理；在处理的过程中，可以提取辅助摄像头采集的部分图像信息对主摄摄像头采集的图像进行补偿，实现对两个摄像头采集的图像进行融合，并经过处理后得到显示的图像，来达到从而提升拍摄质量、背景虚化、光学变焦等功能。示例性地，若电子设备采集图像时为单摄模式，即电子设备开启一个摄像头采集图像，该摄像头即为主摄摄像头。
示例性地，若电子设备采集图像时为双摄模式，即电子设备开启两个摄像头采集图像；其中，一个摄像头为主摄摄像头，另一个摄像头为辅助摄像头；在采集图像时，通常以主摄摄像头采集的图像作为基准，对主摄摄像头采集的图像进行处理；在处理过程中，可以提取部分辅助摄像头采集的部分图像信息对主摄摄像头采集的图像进行补偿，实现对两个摄像头采集的图像进行融合，并经过处理后得到显示的图像，来达到从而提升拍摄质量、背景虚化、光学变焦等功能。
示例性地，若电子设备采集图像时为多摄模式，例如电子设备采集图像时为三摄模式，则电子设备采集图像时可以开启三个摄像头；三个摄像头中包括一个主摄摄像头与两个辅助摄像头；在采集图像时，通常以主摄摄像头采集的图像作为基准，对主摄摄像头采集的图像进行处理；在处理过程中，可以提取两个辅助摄像头采集的部分图像信息对主摄摄像头采集的图像进行补偿，实现对三个摄像头采集的图像进行融合，并经过处理后得到显示的图像，来达到从而提升拍摄质量、背景虚化、光学变焦等功能。
情况1
若电子设备为单摄模式，则电子设备可以关闭广角摄像头；开启超广角摄像头，将超广角摄像头作为主摄摄像头。
情况2
若电子设备为多摄模式(例如，包括双摄模式或者三摄模式)，则电子设备可以将超广角摄像头作为主摄摄像头，辅助摄像头可以全部或者部分开启。
可选地，在电子设备运行超级微距模式之后，可以根据如图15所示的步骤S430至步骤S437确定是否退出超级微距模式。
可选地，可以基于一帧图像判断是否运行超级微距模式；例如，对于一帧图像，若亮度参数大于亮度阈值2且变焦倍率为倍率1且物距1满足第三预设阈值，则电子设备切换摄像头运行超级微距模式。
可选地，为了确保电子设备采集图像的稳定性，电子设备在切换摄像头之前，可以基于多帧图像进行判断；例如，可以判断对于至少连续两帧图像是否物距1满足第一预设阈值，且物距2满足第二预设阈值；若对于至少连续两帧图像物距1满足第一预设阈值，且物距2满足第二预设阈值，则电子设备切换摄像头退出超级微距模式。
在本申请的实施例中，电子设备在确定是否运行超级微距模式时，还可以根据拍摄场景的亮度值、变焦倍率与物距1确定是否运行超级微距模式；在较暗拍摄场景中，对焦的准确性较低即广角摄像头的code值的准确性较低，此时可以确定不运行超级微距模式；从而能够提高运行超级微距模式的准确性。
步骤S554、不运行超级微距模式。
可选地，不运行超级微距模式可以包括电子设备继续运行当前的拍摄模式且不进 入超级微距模式。
在本申请的实施例中，在物距1满足第一预设阈值且物距2满足第二预设阈值时，电子设备切换至将广角摄像头作为主摄摄像头，退出超级微距模式；由于物距2为根据超广角摄像头的参数得到的物距，物距1为根据广角摄像头的参数得到的物距；因此，在本申请的实施例中，在判断是否退出超级微距模式时，会根据双重限制条件确定是否切换摄像头；与现有的方案中，只基于广角摄像头的参数判断是否切换摄像头相比，本申请实施例提供的切换摄像头的方法的准确性更高，即电子设备中拍摄模式的稳定性更好。
此外，在物距1不满足第一预设阈值和/或物距2不满足第二预设阈值的情况下，电子设备可以根据电子设备所处的拍摄环境的亮度参数确定是否退出超级微距模式；进一步地，在拍摄场景的亮度参数不满足退出超级微距模式的情况下，可以根据变焦倍率确定是否退出超级微距模式；基于本申请实施例提供的切换摄像头的方法的准确性更高，即电子设备中拍摄模式的稳定性更好。
应理解，上述步骤S510至步骤S554是以广角摄像头与超广角摄像头之间的切换为例进行描述；步骤S510至步骤S554还可以适用于其他类型的摄像头之间的切换，本申请对摄像头的类型不作任何限定。
可选地，步骤S510至步骤S554还可以适用于广角摄像头与长焦摄像头之间的切换，即上述方法也可以适用于运行超级远景模式、退出超级远景模式或者保持超级远景模式，此处不再赘述。
在一个示例中，在到达预设时间时，电子设备可以继续执行下一次判断流程；例如，电子设备中可以包括定时器，在定时器到达预设时刻(例如，30S)时，电子设备可以继续执行步骤S402至步骤S403，并根据步骤S403的结果执行对应的后续步骤。
应理解，上述步骤S401至步骤S414是以广角摄像头与超广角摄像头之间的切换为例进行描述；步骤S401至步骤S414还可以适用于其他类型的摄像头之间的切换，本申请对摄像头的类型不作任何限定。
