基于上述移动终端硬件结构以及通信网络系统，提出本申请各个实施例。
第一实施例
图3是根据第一实施例示出的处理方法的流程示意图，该处理方法可以适用于摄像头成像的情况，该处理方法可以由本申请实施例提供的一种处理装置来执行，该处理装置可以采用软件和/或硬件的方式来实现，在具体应用中，该处理装置可以具体是终端设备等。所述终端设备可以以各种形式来实施，本实施例中描述的终端设备可以包括设置有至少两个摄像头的诸如手机、平板电脑、笔记本电脑、掌上电脑、个人数字助理(Personal Digital Assistant，PDA)、便捷式媒体播放器(Portable Media Player，PMP)、可穿戴设备、智能手环、计步器等终端设备。本实施例中以所述处理方法的执行主体为终端设备且所述终端设备设置有至少两个摄像头为例，该处理方法包括：
步骤S1：获取至少一拍摄场景信息；
可选地，终端设备在接收到相机开启指令或预设指令后获取拍摄场景信息，或者在拍摄过程中实时、不定时或定期获取拍摄场景信息。
需要说明的是，所述终端设备包括至少两个具有不同目标参数的摄像头，比如具有不同分辨率、和/或不同视场角、和/或不同焦距的多个摄像头，根据拍摄场景的不同，选择与拍摄场景信息匹配的摄像头进行拍摄能够有效提高拍摄效果。此外，在终端设备包括多个摄像头且处于拍照的情况下，所述多个摄像头可能都处于工作状态，也可能只有一个摄像头处于工作状态，通常为默认摄像头处于工作状态，而成像可能是对处于工作状态的一个摄像头所采集的数据进行处理得到的。可选地，所述拍摄场景信息可以根据实际情况需要进行设置，比如，所述拍摄场景信息可包括以下信息中的至少一种：拍摄对象的肤色亮度、环境亮度、终端设备与拍摄对象之间的距离、拍摄对象肤色亮度与环境亮度之间的亮度差、拍摄对象的数量、拍摄对象的类型、拍摄对象在取景画面中所占的比例、终端设备的拍摄角度。这里，拍摄对象的类型可以是人像，也可以是非人像，如车辆、树木、天空、海水、动物等，在此不做具体限定。以拍摄对象的类型为人像为例，不同地区的人的肤色亮度存在差异，例如，非洲人的面部肤色通常比亚洲人的面部肤色要黑，即非洲人的面部肤色亮度低于亚洲人的面部肤色亮度。此外，同一地区的人的肤色亮度也会存在差异。
可选地，若所述拍摄对象的类型为人像，所述获取至少一拍摄场景信息，包括：基于人脸检测技术对拍摄场景中的拍摄对象进行检测，获得所述拍摄对象的肤色亮度。可选地，可先获取对拍摄场景中的人的图像如预览图像，然后基于人脸检测技术如FACE AE工具等对所述图像中的人的肤色亮度进行检测，以获得所述拍摄对象的肤色亮度。如此，能够快速且准确获取拍摄对象的肤色亮度，以实现准确选择对应的摄像头进行拍摄，进一步提升了用户拍摄体验。
可选地，环境亮度可用于表征拍摄对象所在拍摄场景的环境亮度信息，通常，环境越暗，则环境亮度值越小；环境越亮，则环境亮度值越大。在具体应用中，所述环境亮度可以是直接通过光线传感器获取的，也可以是通过图像的亮度等信息获取的。可选地，所述获取至少一拍摄场景信息，包括：根据当前摄像头的拍摄参数获取拍摄场景的环境亮度；可选地，所述拍摄参数可包括光圈大小、曝光时间和感光度值中的至少一种。可以理解地，由于在开启相机应用后，终端设备可以自动根据拍摄场景的环境亮度调节摄像头的拍摄参数，如光圈大小、曝光时间和感光度值等，当然，用户也可主动根据拍摄场景的环境亮度对摄像头的拍摄参数进行调节，也就是说，当前摄像头的拍摄参数与拍摄场景的环境亮度之间存在关联关系，因此，可根据当前摄像头的拍摄参数获取拍摄场景的环境亮度。此外，所述光圈大小、曝光时间以及感光度值之间的对应通常是预先设置的，根据其中一种或两种参数便可获知对应未知参数。如此，能够快速且准确获取拍摄场景的环境亮度，以实现准确选择对应的摄像头进行拍摄，进一步提升了用户拍摄体验。
可选地，所述与拍摄对象之间的距离是指终端设备与拍摄对象之间的距离，可以是直接通过距离传感器获取的，也可以是通过预览图像的景深等信息获取的。所述拍摄对象的数量可以是指需要被拍摄对象的数量，具体可以是预览图像中包含的拍摄对象的数量，以拍摄对象的类型为人像为例，若预览图像中包含多个用户，说明拍摄对象的数量相应有多个。可选地，若所述拍摄对象的类型为人像，所述获取至少一拍摄场景信息，包括：基于人脸检测技术对拍摄场景中的拍摄对象进行检测，获得所述拍摄对象的数量。可选地，可先获取对拍摄场景中的人像的预览图像，然后基于人脸检测技术如FACE AE工具等对所述预览图像中的所述人像进行检测，以获得所述人像的数量。如此，能够快速且准确获取拍摄对象的数量，以实现准确选择对应的摄像头进行拍摄，进一步提升了用户拍摄体验。此外，所述拍摄对象肤色亮度与环境亮度之间的亮度差可用于表征拍摄对象肤色亮度与环境亮度之间的差异大小，所述亮度差越小，说明拍摄对象肤色亮度与环境亮度越接近，而所述亮度差越大，说明拍摄对象的肤色亮度远远高于或低于环境亮度，因此，在所述拍摄对象肤色亮度与环境亮度之间的亮度差较大时，需要采用分辨率大的摄像头进行成像，以提升所述拍摄对象的清晰度。
可选地，所述拍摄对象在取景画面中所占的比例是指拍摄对象在取景画面中所占的面积与取景画面整体面积之间的比值，若所述拍摄对象在取景画面中所占的比例较大，说明用户可能是需要单独拍摄某一物或人，此时为了能够获得所述拍摄对象的整体画面，需要采用视角大的摄像头进行成像。所述终端设备的拍摄角度，也可称为当前摄像头的拍摄角度，具体可通过设置于终端设备内的传感器如陀螺仪、重力感应器、角度感应器等进行获取。
可选地，所述步骤S1，包括：识别预览图像，根据识别结果获取至少一拍摄场景信息。可以理解地，在拍摄对象包含在预览图像中的情况下，通过对预览图像中的拍摄对象进行识别，可以获得拍摄对象的类型、和/或拍摄对象的数量、和/或拍摄对象在取景画面中所占的比例、和/或终端设备与拍摄对象之间的距离等信息。如此，能够便捷且灵活地获取拍摄场景信息，提升了处理效率。
可选地，所述步骤S1，包括：按照各拍摄场景信息的优先级顺序，获取至少一拍摄场景信息。可以理解地，有些拍摄场景信息可能会严重影响拍摄效果，而有些拍摄场景信息可能对拍摄效果的影响较小，此外，受到成像时摄像头使用数量限制等因素影响，可能并不需要考虑所有拍摄场景信息，而只需要考虑其中一种拍摄场景信息即可，因此，可对各拍摄场景信息设置相应的优先级，进而按照各拍摄场景信息的优先级的高低获取至少一拍摄场景信息。如此，根据拍摄场景信息的优先级的高低获取对应的拍摄场景信息，以实现灵活获取拍摄场景信息，进一步提升了用户拍摄体验。
此外，为了避免频繁进行摄像头切换，可按照各拍摄场景信息的优先级的高低获取一个所述拍摄场景信息，而获取的所述拍摄场景信息的优先级可能是最高的，也可能不是最高的。可选地，所述按照各拍摄场景信息的优先级顺序，获取至少一拍摄场景信息，包括以下至少一种：在获取前一优先级对应的拍摄场景信息成功时，获取前一优先级对应的拍摄场景信息；在获取前一优先级对应的拍摄场景信息失败时，获取下一优先级对应的拍摄场景信息。可选地，所述获取前一优先级对应的拍摄场景信息失败，可以是当前拍摄场景不存在前一优先级对应的拍摄场景信息。以最高优先级对应的拍摄场景信息为拍摄对象肤色亮度、且所述拍摄对象为人体、最高优先级的下一优先级对应的拍摄场景信息为环境亮度为例，当只需要获取一个拍摄场景信息时，若拍摄场景中不存在人体，则无法获得人体肤色亮度，即获取最高优先级对应的拍摄场景信息失败，此时可获取最高优先级的下一优先级对应的拍摄场景信息即环境亮度。此外，由于用户通常对人体的拍摄效果比较关注，因此，终端设备在根据拍摄场景信息确定是否需要切换摄像头进行成像时，可设置所述拍摄对象肤色亮度对应的优先级高于其他拍摄场景信息对应的优先级，以在获取拍摄场景信息时，能够先获取拍摄对象肤色亮度或只获取拍摄对象肤色亮度，进而基于拍摄对象肤色亮度确定是否需要切换摄像头进行成像。如此，按照优先级的顺序获取拍摄场景信息，以实现利用用户想要使用的目标摄像头进行成像，进一步提升了用户拍摄体验。
步骤S2：确定所述至少一拍摄场景信息符合预设场景条件时，根据预设策略从所述至少两个摄像头中确定目标摄像头；
可以理解地，对于不同的拍摄场景信息，为了获得较好的拍摄效果，用于成像的摄像头可能对应不同，即需要的目标摄像头不相同。所述符合预设场景条件可以根据实际情况需要进行设置，可选地，若所述拍摄场景信息为拍摄对象的类型，则所述符合预设场景条件可以为所述拍摄对象的类型为人像；若所述拍摄场景信息为终端设备与拍摄对象之间的距离，则所述符合预设场景条件可以为所述终端设备与拍摄对象之间的距离大于或等于预设距离阈值；若所述拍摄场景信息包括拍摄对象的类型和终端设备与拍摄对象之间的距离，则所述符合预设场景条件可以为所述拍摄对象的类型为人像且所述终端设备与拍摄对象之间的距离大于或等于预设距离阈值；若所述拍摄场景信息为拍摄对象的数量，则所述符合预设场景条件可以为拍摄对象的数量为至少两个；若所述拍摄场景信息为拍摄对象在取景画面中所占的比例，则所述符合预设场景条件可以为所述拍摄对象在取景画面中所占的比例大于或等于预设比例阈值；若所述拍摄场景信息为终端设备的拍摄角度，则所述符合预设场景条件可以为终端设备的拍摄角度满足预设角度条件，比如拍摄角度大于预设角度阈值；若所述拍摄场景信息为环境亮度，则所述符合预设场景条件可以为环境亮度满足预设第一亮度条件，比如环境亮度大于第一预设亮度阈值或者环境亮度小于第二预设亮度阈值；若所述拍摄场景信息包括拍摄对象的类型和环境亮度与拍摄对象肤色亮度之间的亮度差，则所述符合预设场景条件可以为拍摄对象的类型为人像、且所述环境亮度与拍摄对象肤色亮度之间的亮度差满足预设第二亮度条件，比如所述亮度差大于预设亮度阈值。如此，基于拍摄场景信息的不同确定对应的目标摄像头，操作灵活且便捷，进一步提升了拍摄效果。
可选地，预设策略可以根据实际情况需要进行设置，可选地，在所述拍摄对象的类型为人像、和/或所述终端设备与拍摄对象之间的距离大于或等于预设距离阈值时，将所述至少两个摄像头中焦距满足第一预设条件的摄像头作为目标摄像头；和/或，在所述拍摄对象的数量为至少两个、和/或所述拍摄对象在取景画面中所占的比例大于或等于预设比例阈值、和/或所述终端设备的拍摄角度满足预设角度条件时，将所述至少两个摄像头中视角满足第二预设条件的摄像头作为目标摄像头；和/或，在所述环境亮度满足第一预设亮度条件时，将所述至少两个摄像头中分辨率满足第三预设条件的摄像头作为目标摄像头；和/或，若所述拍摄对象的类型为人像且所述环境亮度与拍摄对象肤色亮度之间的亮度差满足第二预设亮度条件时，将所述至少两个摄像头中分辨率满足第四预设条件的摄像头作为目标摄像头。可选地，所述将所述至少两个摄像头中分辨率满足第四预设条件的摄像头作为目标摄像头，包括：确定所述环境亮度对应的亮度等级；基于具有不同分辨率的摄像头与亮度等级之间的对应关系，确定分辨率与所述环境亮度对应的亮度等级所匹配的摄像头作为目标摄像头。
可以理解地，在所述拍摄对象的类型为人像时，说明用户可能是在自拍或者为他人拍照，由于可能受到场地大小、手臂长短等因素的限制，使得终端设备与拍摄对象之间的距离较近，可能导致无法拍摄出用户想要的拍摄效果，此时可将所述至少两个摄像头中焦距满足第一预设条件的摄像头作为目标摄像头，比如将所述至少两个摄像头中焦距最大的摄像头作为目标摄像头。此外，在所述终端设备与拍摄对象之间的距离大于或等于预设距离阈值时，说明此时是对处于较远位置的拍摄对象进行拍摄，为了拍摄出清晰的拍摄对象，此时可将所述至少两个摄像头中焦距满足第一预设条件的摄像头作为目标摄像头，比如将所述至少两个摄像头中焦距最大的摄像头作为目标摄像头。需要说明的是，也可以基于终端设备与拍摄对象之间的距离与焦距之间的对应关系，选择与所述距离对应的焦距关联的摄像头作为目标摄像头。
可选地，在拍摄对象的数量较多时，如拍摄班级毕业照、拍摄多棵树时，为了使每个拍摄对象都能够被拍摄到，可以将所述至少两个摄像头中视角满足第二预设条件的摄像头作为目标摄像头，比如将所述至少两个摄像头中视角最宽的摄像头作为目标摄像头。如图4所示，在预览画面中有多个人时，可将视角最宽的摄像头作为目标摄像头。或者，在所述拍摄对象在取景画面中所占的比例大于或等于预设比例阈值时，说明用户可能希望尽可能将拍摄对象全部拍摄到，此时，可以将所述至少两个摄像头中视角最宽的摄像头作为目标摄像头。如图5所示，在预览画面中的树所占的比例较大时，可将视角最宽的摄像头作为目标摄像头。又或者，在所述终端设备的拍摄角度满足预设角度条件时，如所述终端设备的拍摄角度大于预设角度阈值，说明此时用户可能是以从下往上或从上往下的角度进行拍摄，为了尽可能将拍摄对象全部拍摄到，此时，可以将所述至少两个摄像头中视角最宽的摄像头作为目标摄像头。
可选地，第一预设亮度条件和第三预设条件可以根据实际情况需要进行设置，例如，若所述第一预设亮度条件为环境亮度小于第一预设亮度阈值，则所述第三预设条件可以为分辨率最低；若所述第一预设亮度条件为环境亮度大于第二预设亮度阈值，则所述第三预设条件可以为分辨率最高，所述第一预设亮度阈值可以等于或小于所述第二预设亮度阈值。在一实施例中，所述将所述至少两个摄像头中分辨率满足第三预设条件的摄像头作为目标摄像头，包括：确定所述环境亮度对应的亮度等级；基于具有不同分辨率的摄像头与亮度等级之间的对应关系，确定分辨率与所述环境亮度对应的亮度等级所匹配的摄像头作为目标摄像头。可以理解地，对于不同的环境亮度，可预先设置亮度等级划分方式，比如按照需求划分为高、中、低三个亮度等级，并将环境亮度大于200划分为高亮等级，环境亮度大于30且小于200划分为中亮等级，环境亮度小于30划分为低亮等级。对于具有不同分辨率的不同摄像头，可建立具有不同分辨率的摄像头与亮度等级之间的对应关系，进而在获取当前拍摄场景的环境亮度对应的亮度等级后，基于所述对应关系选择分辨率与所述环境亮度对应的亮度等级匹配的摄像头作为目标摄像头进行拍摄。如此，根据具有不同分辨率的摄像头与环境亮度对应的亮度等级之间的对应关系，可快速确定与拍摄场景的环境亮度匹配的目标摄像头，提升了处理速度，进一步提升了用户拍摄体验。
可选地，第二预设亮度条件可以根据实际情况需要进行设置，例如在所述拍摄对象的类型为人像时，若所述环境亮度与拍摄对象肤色亮度之间的亮度差小于预设亮度阈值时，说明环境亮度与拍摄对象肤色亮度之间存在的差异较小，此时可将所述至少两个摄像头中分辨率最大的摄像头作为目标摄像头进行拍摄成像，以能够从成像数据中清楚获知拍摄对象；若所述环境亮度与拍摄对象肤色亮度之间的亮度差大于预设亮度阈值时，说明环境亮度与拍摄对象肤色亮度之间存在较大差异，此时将所述至少两个摄像头中分辨率最小的摄像头作为目标摄像头进行拍摄成像，即可从成像数据中清楚获知拍摄对象。
可选地，所述步骤S2步骤，可包括：基于具有不同目标参数的摄像头与拍摄场景信息之间的对应关系，选择目标参数与所述拍摄场景信息匹配的摄像头作为目标摄像头；可选地，所述目标参数包括以下参数的至少一种：分辨率、视角、焦距。可以理解地，对于具有不同目标参数的不同摄像头，可建立具有不同目标参数的摄像头与拍摄场景信息之间的对应关系，进而在获取当前拍摄场景信息后，基于所述对应关系选择目标参数与所述拍摄场景信息匹配的摄像头作为目标摄像头进行拍摄。以所述终端设备包括第一摄像头和第二摄像头，且所述第一摄像头的分辨率大于所述第二摄像头的分辨率为例，所述基于具有不同目标参数的摄像头与拍摄场景信息之间的对应关系，选择目标参数与所述拍摄场景信息匹配的摄像头作为目标摄像头，以调用所述目标摄像头拍摄，包括：若所述环境亮度大于预设环境亮度阈值，则调用所述第一摄像头进行拍摄；和/或，若所述环境亮度小于或等于预设环境亮度阈值，则调用所述第二摄像头进行拍摄。可选地，终端设备确定所述环境亮度大于预设环境亮度阈值时，则调用所述第一摄像头进行拍摄，以在环境较亮时通过分辨率高的摄像头进行拍摄，从而提升亮光画质；终端设备确定所述环境亮度小于或等于预设环境亮度阈值时，则调用所述第二摄像头进行拍摄，以在环境较暗时通过分辨率低的摄像头进行拍摄，从而提升暗光画质。如此，根据具有不同目标参数的摄像头与拍摄场景信息之间的对应关系，可快速确定与拍摄场景信息匹配的目标摄像头，提升了处理速度，进一步提升了用户拍摄体验。
综上，上述实施例提供的处理方法中，根据拍摄场景信息自动选择对应的摄像头进行成像，以使用户能够随时随地体验到最佳的拍摄效果，且无需用户手动调用摄像头，提升了用户拍摄体验。

可选地，所述方法还可包括：检测到所述目标摄像头所拍摄的图像质量不满足预设要求时，根据所述拍摄场景信息或所述图像的预设信息确定画质增强策略；根据所述画质增强策略，处理所述目标摄像头所拍摄的图像。可以理解地，因受到摄像头性能、拍摄参数等因素的影响，终端设备使用所述目标摄像头所拍摄的图像质量可能不满足预设要求，例如，使用长焦距摄像头所拍摄的图像的清晰度可能小于预设清晰度阈值，或者，拍摄时所采用的感光度较大，使得图像存在明显的噪声等，此时，可根据所述拍摄场景信息或所述图像的预设信息确定画质增强策略，进而根据所述画质增强策略处理所述目标摄像头所拍摄的图像。可选地，所述画质增强策略可以根据实际情况需要进行设置，在一实施例中，所述根据所述拍摄场景信息或所述图像的预设信息确定画质增强策略，包括以下至少一种：若所述拍摄对象的类型为预设类型，则确定需要对所述图像进行色彩增强处理；若所述图像的感光度大于或等于预设感光度阈值，则确定需要对所述图像进行降噪处理；若所述图像的尺寸小于或等于预设尺寸，则确定需要对所述图像进行清晰度提升处理。可选地，若所述拍摄对象的类型为物如花、草等，此时可采用色彩增强算法、和/或同时结合自动对焦、自动曝光、自动白平衡算法以及图像处理算法对所述图像进行色彩增强处理。若所述图像的感光度大于或等于预设感光度阈值，比如所述图像的感光度大于或等于200或400等，则可采用单帧降噪或多帧降噪方式。若所述图像的尺寸小于或等于预设尺寸，比如所述图像的尺寸小于或等于终端设备中多个摄像头同轴的图像输出尺寸的一半或四分之一等，此时认为图像质量较差，则可通过超分算法等对所述图像进行图像增强，以提升图像清晰度。此外，在所述图像的感光度大于或等于预设感光度阈值时，除了可通过降噪算法对图像进行降噪处理之外，还可叠加超分算法对图像进行图像增强处理。如此，结合画质增强策略对图像的整体画质进行提升，进一步提升了用户拍摄体验。

在用户使用终端设备的相机应用拍照的过程中，若用户想要使用某一功能模式进行拍摄，比如用户想要使用人像模式进行拍摄，可点击拍照界面上显示的预设功能按键，以使终端设备检测到预设功能按键操作，此时，可将所述至少两个摄像头中与所述预设功能匹配的摄像头作为目标摄像头，以使拍摄出的图像符合用户需求。例如，假设用户正在使用手机的相机应用拍摄街景，若用户在预览画面的工具栏中点击人像模式，此时手机检测到预设功能按键操作，进而将所述至少两个摄像头中与所述预设功能匹配的摄像头作为目标摄像头。
步骤S20、基于所述目标摄像头进行成像。
可选地，终端设备基于步骤S10所确定的所述目标摄像头进行成像，以输出所述目标摄像头成像的图像。

可选地，所述方法还可包括：检测到所述目标摄像头所拍摄的图像质量不满足预设要求时，根据所述拍摄场景信息或所述图像的预设信息确定画质增强策略；根据所述画质增强策略，处理所述目标摄像头所拍摄的图像。可以理解地，因受到摄像头性能、拍摄参数等因素的影响，终端设备使用所述目标摄像头所拍摄的图像质量可能不满足预设要求，例如，使用长焦距摄像头所拍摄的图像的清晰度可能小于预设清晰度阈值，或者，拍摄时所采用的感光度较大，使得图像存在明显的噪声等，此时，可根据所述拍摄场景信息或所述图像的预设信息确定画质增强策略，进而根据所述画质增强策略处理所述目标摄像头所拍摄的图像。可选地，所述画质增强策略可以根据实际情况需要进行设置，在一实施例中，所述根据所述拍摄场景信息或所述图像的预设信息确定画质增强策略，包括以下至少一种：若所述拍摄对象的类型为预设类型，则确定需要对所述图像进行色彩增强处理；若所述图像的感光度大于或等于预设感光度阈值，则确定需要对所述图像进行降噪处理；若所述图像的尺寸小于或等于预设尺寸，则确定需要对所述图像进行清晰度提升处理。可选地，若所述拍摄对象的类型为物如花、草等，此时可采用色彩增强算法、和/或同时结合自动对焦、自动曝光、自动白平衡算法以及图像处理算法对所述图像进行色彩增强处理。若所述图像的感光度大于或等于预设感光度阈值，比如所述图像的感光度大于或等于200或400等，则可采用单帧降噪或多帧降噪方式。若所述图像的尺寸小于或等于预设尺寸，比如所述图像的尺寸小于或等于终端设备中多个摄像头同轴的图像输出尺寸的一半或四分之一等，此时认为图像质量较差，则可通过超分算法等对所述图像进行图像增强，以提升图像清晰度。此外，在所述图像的感光度大于或等于预设感光度阈值时，除了可通过降噪算法对图像进行降噪处理之外，还可叠加超分算法对图像进行图像增强处理。如此，结合画质增强策略对图像的整体画质进行提升，进一步提升了用户拍摄体验。
第三实施例
图8是根据第三实施例示出的处理方法的具体流程示意图，本实施例中以所述终端设备为搭载有后置双摄像头的手机，后置双摄像头分别命名为01和02，其中01作为主摄模组、02作为2M暗光模组为例，如图9所示。可选地，本实施例的处理方法包括但不限于以下步骤：

步骤S304：启用01摄像头进行预览；
步骤S305：启用02摄像头进行预览；
步骤S306：接收录制指令，开始录制视频。
图10为在暗环境调用主摄模组进行拍摄的效果示意图，图11为在暗环境调用2M暗光模组进行拍摄的效果示意图，对比可知，在暗环境下自动调用2M暗光模组进行拍摄的效果优于采用主摄模组进行拍摄的效果。
综上，上述实施例提供的处理方法中，先通过对比测试主摄和2M暗光模组的效果优劣，确定调用亮度环境即亮度阈值，在对应的亮度环境下通过BV值对应环境亮度变化，BV值越大环境越亮。当用户点击相机进入视频模式时，通过BV检测确认环境亮度，选择调用的摄像头；接着，在进入视频模式后，根据用户点击录制操作而保持录制视频。因此，本实施例提供了一个自动视频暗光调用解决方案，满足用户简单易用需求；暗光模组价值得到最大化，使视频暗拍效果达到最佳；此外，无需设计调用图标（icon），不影响现有相机界面的排布。
