具体实施方式
本申请涉及拍摄领域，为了便于理解本申请提供的方法，下面对拍摄领域的一些术语进行介绍。
1.合并(binning)
binning是一种图像读出模式，将相邻的像元中感应的电荷被加在一起，以一个像素的模式读出。例如，电子设备在拍摄图像的过程中，目标对象反射的光线被摄像头采集，以使得该反射的光线传输至图像传感器。图像传感器上包括多个感光元件，每个感光元件采集到的电荷为一个像素，并对像素信息执行binning操作。具体地说，binning可以将n×n个像素合并为一个像素。例如，binning可以将相邻的2×2个像素合成为一个像素，也就是说，相邻2×2个像素的颜色以一个像素的形式呈现。
示例性的，图1为本申请实施例提供的一种合并以及DCG的原理示意图。如图1所示，当图像为一个4×4的像素时，binning可以实现将相邻的2×2个像素合成为一个像素，使得图像传感器可以将4×4的图像合并为2×2的图像，并将该2×2的图像作为图像传感器基于binning的图像输出。
2.双转换增益(dual conversion gain，DCG)
具有双转换增益DCG能力的图像传感器，一个像素有两个势阱，两个势阱对应不同的满阱容量以及不同的转换增益CG，大满阱容量对应低转换增益(low conversion gain，LCG)、低感光度，小满阱容量对应高转换增益(high conversion gain，HCG)、高感光度。这样，传感器可以在同一场景下使用两个势阱(两种感光度)和两种转换增益，一次曝光获取两张图像：高感光模式下的图像和低感光模式下的图像。再由电子设备将获取的两张图像合成一张图像，也就是HDR技术。
示例性的，如图1所示，在将相邻的n×n个像素合成一个像素之后，图像传感器可以进一步的使用两种转换增益，例如分别基于HCG以及LCG得到两种转换增益下的出图数据，对该基于HCG的出图数据以及基于LCG的出图数据进行融合，得到融合后的图像，并将该融合后的图像作为图像传感器基于DCG的图像输出。
为了便于清楚描述本申请实施例的技术方案，在本申请的实施例中，采用了“第一”、“第二”等字样对功能和作用基本相同的相同项或相似项进行区分。例如，第一值和第二值仅仅是为了区分不同的值，并不对其先后顺序进行限定。本领域技术人员可以理解“第一”、“第二”等字样并不对数量和执行次序进行限定，并且“第一”、“第二”等字样也并不限定一定不同。
需要说明的是，本申请中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其他实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
本申请中，“至少一个”是指一个或者多个，“多个”是指两个或两个以上。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B的情况，其中A，B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项(个)”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a，b，或c中的至少一项(个)，可以表示：a，b，c，a和b，a和c，b和c，或a、b和c，其中a，b，c可以是单个，也可以是多个。
随着技术的发展，用户对手机等终端设备所拍摄的视频的拍摄效果的要求越来越高，因此较多终端设备可以支持拍摄得到HDR视频。然而受终端设备的HDR能力的限制，HDR视频可以支持的帧率通常为30帧/秒(fps)，则无法实现对于明亮场景、运动场景、以及夜景等拍摄场景对于不同帧率的需求，进而影响视频拍摄效果。其中，该HDR能力可以包括：基于交错(stagger)HDR的成像方法、以及基于DCG成像方法。
示例性的，针对运动场景以及高亮场景，无论是基于stagger HDR的成像方法还是基于DCG的成像方法均只能支持30fps的帧率，这就对高亮场景、或运动场景等需要展现更多的画面信息的拍摄场景造成影响。例如，当终端设备采用帧率为30fps拍摄运动场景时，由于帧率数值较小，使得拍摄得到的视频可能出现卡顿的情况，进而影响视频的平滑程度。
示例性的，针对暗光场景，基于DCG的成像方法将会在暗光场景中产生噪声等问题。可以理解的是，由于基于DCG的成像方法是基于HCG以及LCG共同确定的，因此基于DCG的成像方法输出的图像数据是基于HCG得到的图像数据以及4倍基于LCG得到的图像数据的合并得到的。由于在拍摄暗光场景中，基于LCG得到的图像数据比基于HCG得到的图像数据具有更大的噪声，因此在暗光场景下LCG的噪声被放大，因而基于DCG方法拍摄暗光场景时，视频的拍摄效果较差。
因此，无论是在运动场景或高亮场景中由于帧率较小对视频的平滑程度造成影响，还是在暗光场景中基于DCG的成像方法带来的噪声较大的问题，都会影响最终的视频拍摄效果。
有鉴于此，本申请实施例提供一种视频处理方法，终端设备可以为拍摄场景匹配合适的帧率，并根据拍摄场景的变换，对帧率进行动态调整，使得终端设备可以基于不同的帧率得到拍摄效果较好的视频。
可以理解的是，上述终端设备也可以称为终端，(terminal)、用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)等。终端设备可以为支持视频录制功能的手机(mobile phone)、智能电视、穿戴式设备、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)设备、增强现实(augmented reality，AR)设备、工业控制(industrial control)中的无线终端、无人驾驶(self-driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无 线终端、智慧家庭(smart home)中的无线终端等等。本申请的实施例对终端设备所采用的具体技术和具体设备形态不做限定。

感知模块用于基于预览画面的亮度情况、拍摄对象、终端设备的状态数据(如陀螺仪数据、以及加速度数据)等数据对拍摄场景进行识别，并且将识别到的场景发送至决策模块。其中，感知模块可以基于自动曝光控制模块对预览画面的灰度直方图、以及预览画面中的像素点的灰度情况进行统计。
决策模块用于基于拍摄场景与帧率之间的对应关系为不同的拍摄场景匹配合适的帧率，并且指示摄像头中的相应传感器输出该帧率对应的图像序列。
可能的实现方式中，该感知模块、决策模块、以及自动曝光模块的位置可以根据需求设置在其他层中，本申请实施例中对此不做限定。
可能的实现方式中，该硬件抽象层中可以还包括：音频接口、视频接口、通话接口、以及全球定位提供(global positioning system，GPS)接口等(图3中未示出)。
内核层是硬件和软件之间的层。内核层中可以包含：显示驱动、以及摄像头驱动等。
本申请实施例中，该摄像头驱动中可以设置有不同的图像传感器设置(sensor setting)策略，使得终端设备可以实现不同帧率下的sensor setting的切换。示例性的，表1为本申请实施例提供的一种sensor setting示意表。
表1 sensor setting示意表
Figure PCTCN2023071381-appb-000001
如表1所示，sensor setting中可以包括：DCG设置信息以及binning设置信息等。其中，该DCG设置信息可以支持的出图数据可以包括：帧率为30fps、支持12比特bit的数据存储、输出格式为RAW12、以及支持相位对焦PDAF等；该binning设置信息可以支持 的出图数据可以包括：帧率1fps-60fps、支持12bit的数据存储、输出格式为RAW12、以及支持PDAF等。
可以理解的是，该binning设置信息可以同时支持：sensor工作模式为binning24对应的24fps的帧率、sensor工作模式为binning30对应的30fps的帧率、以及sensor工作模式为binning60对应的60fps的帧率。
可以理解的是，binning只有高10bit有数据，因此binning需要做低两位补充处理，以保证12bit的数据存储。
可能的实现方式中，任一组sensor setting中可以支持的出图数据还可以包括：出图分辨率、出图速率、以及数据传输速率等。
可以理解的是，sensor setting中DCG设置信息以及binning设置信息中的数据传输速率以及支持数据存储的位数的一致性，可以实现图像传感器中的DCG对应的sensor工作模式以及binning对应的sensor工作模式之间的无缝切换。其中，在DCG对应的sensor工作模式以及binning对应的sensor工作模式进行模式切换时，可以会拉长一帧的10毫秒-20毫秒，并对图像后处理中的防抖处产生一个移码(frame shift)。
可能的实现方式中，表1仅作为sensor setting的一种示例，可能的实现方式中，该sensor setting中还可以包括更多设置信息，本申请实施例中对此不做限定。
可以理解的是，binning以及DCG可以对应于不同的动态范围收益(dynamic range DR)。示例性的，图4为本申请实施例提供的一种图像感光度(ISO值)与动态范围收益的示意图。在图4对应的实施例中，横轴为ISO值，纵轴为DR(db)。
ISO值越低，拍摄场景的亮度越高，基于binning以及DCG分别得到的图像的DR越高，相比于binning以及DCG，DCG在亮度越高的场景下具有更好的DR，因而DCG更适合用在亮度较高的场景下。
ISO值越高，拍摄场景越暗，曝光时间越短，基于binning以及DCG分别得到的图像的DR越低，由于binning以及DCG在越暗的场景下噪声越大，因此通常采用帧率为30fps获取暗光场景的图像数据，而相比于binning以及DCG，binning的功耗低于DCG，因此终端设备可以倾向于采用binning获取暗光场景下的图像数据。
下面结合视频生成场景以及图3对应的实施例，示例性说明第一设备的软件以及硬件的工作流程。
触摸传感器接收到用户针对相机应用中的录像模式的开启操作时，相应的硬件中断被发给内核层，内核层将触摸操作加工成原始输入事件(包括触摸坐标，触摸操作的时间戳等信息)，原始输入事件被存储在内核层。应用程序框架层从内核层获取原始输入事件，识别该输入事件所对应的控件。进而相机应用调用应用框架层的接口，启动相机应用中的录像模式。相机应用通过程序框架层中的相机API、系统库中的相机服务、指示硬件抽象层中的感知模块对拍摄画面进行场景识别，并将识别到的场景发送至决策模块；决策模块基于拍摄场景与sensor工作模式的对应关系，为当前拍摄场景确定合适的sensor工作模式，并将该sensor工作模式发送至内核层中的摄像头驱动，使得摄像头驱动可以基于该sensor工作模式对应的sensor setting采集图像序列；摄像头驱动将采集的图像序列分为预览流以及录像流，将预览流发送至表面视图，将录像流发送至媒体录制进行编码并存储在终端设备中。
下面以具体地实施例对本申请的技术方案以及本申请的技术方案如何解决上述技术问题进行详细说明。下面这几个具体的实施例可以独立实现，也可以相互结合，对于相同或相似的概念或过程可能在某些实施例中不再赘述。
可以理解的是，为了保证终端设备可以根据拍摄场景对视频录制过程中的帧率进行自动调节，终端设备可以设置自动视频帧率。
示例性的，图5为本申请实施例提供的一种设置视频帧率的界面示意图。在图5对应的实施例中，以终端设备为手机为例进行示例说明，该示例并不构成对本申请实施例的限定。
当终端设备接收到用户开启相机应用的操作时，终端设备可以显示图5中的a所示的界面，该界面可以为相机应用的主界面(或理解为拍照模式对应的界面)。如图5中的a所示，该界面中可以包括下述一种或多种，例如：拍照模式对应的拍照控件、预览图像、用于开启人工智能(artificial intelligence，AI)摄影功能的控件、用于开启或关闭闪光灯控件、用于对相机应用进行设置的设置控件501，用于调整拍摄倍数的控件、用于翻转摄像头的控件、以及用于打开图库的控件等。该图5中的a所示的界面中还可以包括相机应用的一级菜单中的多个功能控件，例如：用于开启夜景模式的控件、用于开启人像模式的控件、用于开启拍照模式的控件、用于开启录像模式的控件502、以及用于开启电影模式的控件等。其中，该用于打开图库的控件可用于开启图库应用程序。图库应用程序是智能手机、平板电脑等电子设备上的一款图片管理的应用程序，又可以称为“相册”，本实施例对该应用程序的名称不做限制。图库应用程序可以支持用户对存储于终端设备上的视频进行各种操作，例如浏览、编辑、删除、选择等操作。

可能的实现方式中，终端设备也可以基于除图5中的a所示的界面以外的其他界面，进入如图5中的b所示的设置界面，本申请实施例对此不做限定。
在如图5中的b所示的界面中，当终端设备接收到用户针对视频帧率功能控件503的操作时，终端设备可以显示图5中的c所示的界面。如图5中的c所示的界面，该界面中可以包括视频帧率提示框504，该视频帧率提示框504中可以包括：用于设置帧率为50fps的选项、用于设置帧率为60fps的选项、以及用于设置帧率为自动的选项505等。其中，如图5中的c所示的界面中，该用于设置帧率为50fps的选项可以为选中状态，该界面中 显示的其他内容可以与图5中的b所示的界面类似，在此不再赘述。
在如图5中的c所示的界面中，当终端设备接收到用户针对用于设置帧率为自动的选项505的操作时，终端设备可以显示图5中的d所示的界面。如图5中的d所示的界面，该界面中的用于设置帧率为自动的选项505可以为选中状态，且该界面中显示的其他内容可以与图5中的d所示的界面类似，在此不再赘述。
可能的实现方式中，在帧率设置为自动的情况下，相机应用中的录像模式可以支持的变焦范围为1x-10x；录像模式可以实现在视频分辨率为4K对应的场景下不可以支持美颜以及滤镜等功能；录像模式中可以支持主摄工作，不支持多摄切换。
可以理解的是，在终端设备基于图5对应的实施例中将帧率设置为自动的情况下，终端设备则可以基于下述图6对应的视频处理方法，在开始视频录制时为拍摄场景匹配合适的帧率，进而使得终端设备可以录制得到视频画面效果较好的视频。
示例性的，图6为本申请实施例提供的一种视频处理方法的流程示意图。
如图6所示，视频处理方法可以包括如下步骤：
S601、当终端设备接收到用户在相机应用中开始视频录制的操作时，终端设备利用感知模块确定拍摄场景。
本申请实施例中，该相机应用可以为终端设备的系统支持的应用，或者该相机应用也可以为具有视频录制功能的应用等；该开始视频录制的操作可以为语音操作、或者也可以为针对录像模式中的用于开始拍摄的控件的点击操作或滑动操作等；该感知模块所在位置以及作用可以参见图2对应的实施例中的描述，在此不再赘述。
示例性的，图7为本申请实施例提供的一种开启视频录制的界面示意图。在如图5中的a所示的界面中，当终端设备接收到用户针对用于开启录像模式的控件502的操作时，终端设备可以显示图7中的a所示的界面。该图7中的a所示的界面中可以包括：用于开启或关闭闪光灯控件、用于对相机应用进行设置的设置控件、以及用于开启视频录制的控件701等，该界面中显示的其他内容可以与图5中的a所示的界面类似，在此不再赘述。
在如图7中的a所示的界面中，当终端设备接收到用户针对用于开启视频录制的控件701的操作时，终端设备可以显示图7中的b所示的界面。该图7中的b所示的界面中可以包括：用于结束视频录制的控件702、用于暂停视频录制的控件、用于在视频录制过程中拍摄的控件、用于指示视频拍摄时间的数字信息、用于开启或关闭闪光灯控件、以及用于调整拍摄时的镜头放大倍数的控件等。
进一步的，在终端设备基于图7对应的实施例开启视频录制的情况下，终端设备可以利用感知模块确定拍摄场景。
示例性的，终端设备的感知模块可以基于陀螺仪传感器以及加速度传感器感知终端设备的状态，例如终端设备为手持状态、或终端设备为三脚架状态。进一步的，在手持状态或三脚架状态下，终端设备的感知模块还可以基于自动曝光控制模块统计预览画面的亮度情况，确定当前是否满足HDR场景、高亮场景、或暗光场景等；或者，终端设备的感知模块还可以基于拍摄场景中是否具有跑马灯的预设图案确定当前是否满足预设的跑马灯场景。其中，该跑马灯场景可以为拍摄场景中具有跑马灯的预设图案的场景；跑马灯的预设图案为用于测试视频帧率的循环显示的图案，例如循环点亮的灯泡图案等。
具体的，终端设备的感知模块基于陀螺仪传感器以及加速度传感器感知终端设备的状态的一种可能的实现可以为：终端设备的感知模块可以获取基于陀螺仪传感器检测到的角加速度数据，以及基于加速度传感器检测到的加速度数据，由于相比于三脚架状态，手持状态下用户的抖动较为明显，使得检测到的角速度数据以及角速度数据的数值较大。因此，当感知模块确定角加速度数据大于角加速度阈值，和/或加速度数据大于加速度阈值时，则终端设备可以确定当前为手持状态；或者，当感知模块确定角加速度数据小于等于角加速度阈值，和/或加速度数据小于或等于加速度阈值时，则终端设备可以确定当前为三脚架状态。
具体的，终端设备的感知模块可以统计预览画面的亮度情况，确定当前是否满足HDR场景、高亮场景、或暗光场景等的一种可能的实现可以为：终端设备可以对预览画面进行4倍下采样得到预览小图，并确定该预览小图中的高亮像素的个数占预览小图中的所有像素的比例是否大于HDR场景对应的第一像素阈值，或者，该预览小图中的高亮像素的个数占预览小图中的所有像素的比例是否大于高亮场景对应的第二像素阈值，或者，该预览小图中的暗光像素的个数占预览小图中的所有像素的比例是否大于暗光场景对应的第三像素阈值。或者，终端设备中可以设置典型的HDR场景、高亮场景、或暗光场景等分别对应的灰度直方图，因此终端设备可以获取预览画面对应的灰度直方图，并确定该预览画面对应的灰度直方图与该典型的HDR场景、高亮场景、或暗光场景等分别对应的灰度直方图之间的相似度，进而确定当前的拍摄场景。其中，该高亮场景以及暗光场景等均可以为非HDR场景。其中，该高亮场景也可以基于拍摄场景的亮度确定，例如当该拍摄场景不满足HDR场景，且拍摄场景的亮度大于(或大于等于)亮度阈值时，则为高亮场景；或者，当该拍摄场景不满足HDR场景，且拍摄场景的亮度小于(或小于等于)亮度阈值时，则为暗光场景。
具体的，终端设备的感知模块基于拍摄场景中是否具有跑马灯的预设图案确定当前是否满足预设的跑马灯场景的一种可能的实现可以为：终端设备可以基于预设的AI模型，对当前拍摄场景中的对象进行识别，当终端设备基于预设的AI模型识别拍摄场景中包含如广告牌等跑马灯的预设图案时，则可以确定当前满足跑马灯场景。
可能的实现方式中，除了实际拍摄视频的场景之外，电子设备的视频录制过程还有可能用于某些测试过程中，测试过程会使用特定的预设图案来进行测试，为了更好匹配特定的测试过程，因此，可以基于预设图案结合场景和高亮情况来切换sensor工作模式。
可以理解的是，终端设备的感知模块也可以基于其他方法对终端设备的状态、当前的亮度场景以及跑马灯场景等进行识别，本申请实施例中对此不做具体限定。
S602、终端设备利用决策模块确定拍摄场景对应的sensor工作模式。
本申请实施例中，决策模块中可以存储有拍摄场景与sensor工作模式之间的对应关系。
可能的实现方式中，决策模块还可以基于终端设备的温度，例如终端设备的温度大于温度阈值时对应的高温状态，匹配相应的sensor工作模式。这样，使得终端设备可以通过降低帧率，避免高温对于终端设备的影响。
示例性的，表2为本申请实施例提供的一种拍摄场景与sensor工作模式的对应关系示意表。
表2拍摄场景与sensor工作模式的对应关系示意表
Figure PCTCN2023071381-appb-000002
可以理解的是，DCG(或binning)的动态范围收益DR与图像感光度(ISO值)之间的关系可以为：ISO值越高(或理解为越到暗光场景)，DCG(或binning)的DR值越小，因此可以采用帧率为30fps的出图方式；并且，由于DCG在暗光场景下具有较大的噪声，因此在暗光场景中可以采用binning30。
下面结合表2对应的拍摄场景与sensor工作模式的对应关系，对不同场景中sensor工作模式的切换进行示例说明。
本申请实施例中，当图像传感器启动时，图像传感器可以默认启动DCG30。
进一步的，在图像传感器默认启动DCG30的情况下，终端设备可以通过对手持状态以及三脚架状态的识别，确定不同的工作模式。其中，该手持状态以及三脚架状态的确定方法可以参见S601所示的步骤中的描述，在此不再赘述。
一种实现中，当终端设备确定当前为手持状态，且满足HDR场景时，终端设备可以确定当前场景可以采用DGC30，进而指示图像传感器，使得图像传感器可以继续保持DCG30的工作模式。
另一种实现中，当终端设备确定当前为手持状态，且满足高亮场景时，终端设备可以确定当前场景可以采用binning60，进而指示图像传感器，使得图像传感器可以由DCG30切换至binning60。
可能的实现方式中，在图像传感器为binning60的情况下，当终端设备确定当前为手持状态，且满足HDR场景时，终端设备可以确定当前场景可以采用DCG30，进而指示图像传感器。图像传感器接收到该DCG30时，可以先由binning60降为binning30，再由binning30切换至DCG30。可以理解的是，图像传感器由binning60降为binning30，再由binning30切换至DCG30的方式，可以避免图像传感器出现DCG60的情况，提高图像传感器对于图像输出的稳定性。
再一种实现中，当终端设备确定当前为手持状态，且满足暗光场景时，终端设备可以确定当前场景可以采用binning30，进而指示图像传感器，使得图像传感器可以由DCG30切换至binning30。
又一种实现中，当终端设备确定当前为三脚架状态，且满足跑马灯场景时，终端设备可以确定当前场景可以采用binning60，进而指示图像传感器，使得图像传感器可以由DCG30切换至binning60。
又一种实现中，当终端设备确定当前为三脚架状态，且不满足跑马灯场景(或理解为满足非跑马灯场景)时，终端设备可以确定当前场景可以采用DCG30，进而指示图像传感 器，使得图像传感器可以继续保持DCG30的工作模式。
又一种实现中，当终端设备确定当前终端设备的温度大于温度阈值时，则终端设备可以确定当前场景可以采用binning24，进而指示图像传感器，使得图像传感器可以由DCG30切换至binning24。
可以理解的是，当终端设备确定当前终端设备的温度大于温度阈值时，终端设备可以不用对其他场景进行识别就可以确定采用binning24的工作模式。
进一步的，决策模块可以将sensor工作模式发送图像传感器。
S603、终端设备利用与sensor工作模式匹配的sensor setting拍摄得到图像序列。
本申请实施例中，终端设备的摄像头可以基于表1，确定工作模式所对应的sensor setting，并基于该sensor setting中的出图数据获取图像序列。
可以理解的是，当终端设备的决策模块确定sensor工作模式，由DCG对应的工作模式切换至binning对应的工作模式，或者由binning对应的工作模式切换至DCG对应的工作模式时，终端设备可以基于该切换后的工作模式对应的sensor setting获取图像序列；进一步的，则自动曝光模块、图像前处理(或称图像信号处理器前端处理)、以及图像后处理(或称图像信号处理器后端处理)等处理过程中涉及的参数可以按照切换后的sensor工作模式进行调整。
如图6中的摄像头对应的虚线框所示，摄像头用于采集图像，当被拍摄对象的反射光通过镜头，在镜片上折射后，汇聚在图像传感器上。图像传感器可以将光信号转换成模拟电信号。该模拟电信号从传感器前端输出，再经过数模转换器输出。可以理解的是，数模传感器输出的为摄像头采集的原始数字图像，即RAW格式的图像。
S604、终端设备对图像序列进行图像前处理，得到图像前处理后的图像序列。
本申请实施例中，该图像前处理用于将基于摄像头获取的RAW(或称为原始图像数据)格式的图像，处理为YUV(或理解为亮度和色度)格式的图像。
可以理解的是，该图像前处理过程可以包括下述一种或多种，例如：去坏点校正处理、RAW域降噪处理、黑电平校正处理、光学阴影校正处理、自动白平衡处理、颜色插值处理、色彩校正处理、全局色调映射处理、或图像转换处理等，本申请实施例中对该图像前处理过程不做限定。
如图6中的图像信号处理器对应的虚线框，图像信号处理器用于将来自摄像头的RAW格式的图像进行相关处理并生成待显示的图像。进一步的，图像信号处理器可以将待显示的图像发送给显示屏进行显示。图像信号处理器中可以包括：图像处理器前端对应的图像前处理、以及图像处理器后端对应的图像后处理等。
S605、终端设备将图像前处理后的图像序列分别作为预览流以及录像流，并进行图像后处理，得到预览流对应的图像后处理后的第一图像序列、以及录像流对应的图像后处理后的第二图像序列。
本申请实施例中，该图像后处理可以包括下述一种或多种，例如：图像矫正及调整处理、局部色调映射处理、以及伽马(Gamma)校正处理等步骤。
在图像矫正及调整处理中，终端设备可以对当前图像进行防抖处理，例如对当前图像数据进行裁剪，使得裁剪后的图像可以抵消由于终端设备的抖动带来的影响。示例性的，终端设备可以利用陀螺仪传感器获得角加速度数据，并通过电子防抖处理获取当前图像对 应的变换(warp)矩阵。进一步的，终端设备可以利用warp矩阵，对当前图像数据进行裁剪，如分别在当前图像数据的横纵方向各裁剪掉图像数据的10％-20％等，从而抵消抖动带来的影响。
在局部色调映射处理中，终端设备可以实现对图像的整体亮度进行调整，使得亮度调整后的画面可以更接近于真实世界中呈现的亮度。在Gamma校正处理中，终端设备可以对图像进行亮度调整，使其可以保留更多的亮部和暗部细节，压缩对比度，保留更多的色彩信息。
可能的实现方式中，终端设备可以将第一图像序列发送至显示屏进行显示，使得第一图像序列可以显示在终端设备的预览界面中，例如显示在如图7中的b所示的界面。并且，当终端设备接收到用户在图7中的b所示的界面中针对用于结束视频录制的控件702的操作时，终端设备可以对第二图像序列进行编码并存储为视频，使得终端设备可以在接收到用户查看该视频的操作时播放视频。
基于此，终端设备可以为拍摄场景匹配合适的帧率，并根据拍摄场景的变换，对帧率进行动态调整，使得终端设备可以基于不同的帧率得到拍摄效果较好的视频。
可以理解的是，本申请实施例提供的界面仅作为一种示例，并不能构成对本申请实施例的限定。
基于上述实施例中所描述的内容，为了更好的理解本申请各实施例，示例性的，图8为本申请实施例提供的另一种视频处理方法的流程示意图。

S802、响应于开始视频录制的操作，终端设备启动视频录制。
S803、终端设备利用第一拍摄参数，采集拍摄场景的第一图像序列。
S804、终端设备根据拍摄场景调整拍摄参数，得到第二拍摄参数。
其中，第一拍摄参数用于指示终端设备基于双转换增益DCG进行视频录制时所采用的拍摄参数。可以理解的是，该第一拍摄参数可以为本申请实施例中的DCG设置信息；第二拍摄参数可以为本申请实施例中的binning设置信息，该DCG设置参数以及binning设置操作的描述可以参见表1对应的实施例，在此不再赘述。
S805、终端设备利用第二拍摄参数，采集拍摄场景的第二图像序列。
S806、终端设备基于第一图像序列以及第二图像序列，得到视频处理结果。
其中，终端设备可以基于图6对应的实施例中的S604-S605对第一图像序列以及第二图像序列进行处理，得到视频处理结果。
可以理解的是，该第一图像序列以及第二图像序列均可以为预览流对应的图像序列，或者也可以为录像流对应的图像序列。
这样，终端设备可以为拍摄场景匹配合适的拍摄参数，并根据拍摄场景的变换，对拍摄参数进行动态调整，使得终端设备可以基于不同的拍摄参数得到拍摄效果较好的视频。
