Description

一种视频处理方法和移动设备 技术领域
本申请涉及终端技术领域，尤其涉及一种视频处理方法和移动设备。
背景技术
手机中相机应用的拍照或视频录制功能已经成为用户使用频率较高的功能之一。现在，用户更希望使用手机能够拍摄(或录制)出更有趣味性的图像(或视频)。
请参见图1所示，为现有技术中手机中相机应用的区域界面的示意图。取景界面中包括两种视频录制模式。其中一种为慢动作拍摄，另一种为延时拍摄。当用户选择慢动作拍摄视频时，假设手机1秒采集480帧图像，且录制2s，即手机得到的视频中包括960帧图像，手机以每秒30帧的速率播放该视频，播放完960帧图像需要使用32s，即手机将视频内容慢速的呈现给用户(将录制2秒的视频使用32秒播完)。当用户选择延时摄影时，假设手机1秒采集15帧，且录制2s，即手机得到的视频中包括30帧图像，手机以30fps播放该视频时，只需1秒播完，即手机将视频内容快速的呈现给用户(将录制2秒的视频使用1秒播完)。
综上，现有技术中，无论慢动作录制还是延时摄影，手机都是对整个视频画面的快速或慢速呈现。但是，如果一段视频是通过延时摄影的方式录制的，那么这段视频播放时只能快速播放，如果视频中有用户感兴趣的内容，那么感兴趣的内容也会快速播放，用户就无法更好的查看这部分内容。
发明内容
本申请提供一种视频处理方法和移动设备，该方法可以使视频中不同内容以不同的播放速度播放。
第一方面提供一种视频处理方法，该方法可以由具有显示屏的电子设备(比如手机、ipad、笔记本电脑等)执行，该方法包括：检测到用于播放视频文件的第一操作；所述视频文件是所述电子设备中存储的视频文件；响应于所述第一操作，播放所述视频文件，所述视频文件中第一目标对象的播放速度大于所述视频文件中所述第一目标对象以外的其它对象的播放速度；检测到用于更换目标对象的第二操作；响应于所述第二操作，继续播放所述视频文件，在继续播放所述视频文件的过程中，所述视频文件中的第二目标对象的播放速度大于所述第二目标对象以外的其它对象的播放速度；所述第二目标对象是所述视频文件中与所述第一目标对象不同的至少一个对象。
应理解，电子设备播放视频文件时，视频文件中的目标对象可以快速播放，而且目标对象可以切换，比如，视频文件中的某个目标对象快速播放，其它对象正常播放，当切换目标对象之后，该视频文件中的另一个目标对象快速播放，其它对象正常播放。通过这种方式，用户可以快速观看视频文件中的用户感兴趣对象，提升视频播放的趣味性，提升用户体验。
在一种可能的设计中，所述第一目标对象包括：预设的目标对象；或者为所述电子设备根据所述视频文件中的多个对象自动确定的对象；或者，为所述电子设备根据用户在所述视频文件中的一帧图像上的选定操作，确定的对象；所述第二目标对象包括：预 设的目标对象；或者，所述电子设备根据所述视频文件中的多个对象自动确定的对象；或者，所述电子设备根据用户在所述视频文件中的一帧图像上的选定操作，确定的对象。
应理解，视频文件中的目标对象可以是预先设置的，或者电子设备自动确定的，或者是用户选择的。通过这种方式，用户可以快速观看视频文件中的用户感兴趣对象，提升视频播放的趣味性，提升用户体验。
在一种可能的设计中，所述第一目标对象或者所述第二目标对象的播放速度为预设的播放速度；或者，所述第一目标对象或者所述第二目标对象的播放速度为所述电子设备根据用户在所述视频文件中的一帧图像上的选择操作，确定的播放速度。
应理解，视频文件中目标对象的播放速度可以是预先设置的，或者用户选择的。通过这种方式，用户可以快速观看视频文件中的用户感兴趣对象，提升视频播放的趣味性，提升用户体验。
在一种可能的设计中，所述第二目标对象为所述电子设备根据用户在所述视频文件中的一帧图像上的选定操作，确定的对象，包括：检测到作用在所述一帧图像上的至少一个点击操作，确定每个点击操作所在位置对应的对象为所述第二目标对象；或者检测到作用在所述一帧图像上的至少一个圈选操作，确定每个圈选操作所围成的区域内包括的对象为所述第二目标对象；或者检测到作用在所述一帧图像上的每个对象的标识信息中选择至少一个目标标识信息的操作，确定所述一帧图像上每个目标标识信息对应的对象为所述第二目标对象。
应理解，用户选择目标对象的方式可以有多种，比如在视频文件的一帧图像上点击对象，或者圈选对象，或者根据目标对象的标识选择对象，方便用户操作，提升用户体验。
在一种可能的设计中，所述第二目标对象的播放速度为所述电子设备根据用户在所述视频文件中的一帧图像上的选择操作，确定的播放速度，包括：响应于触发显示播放速度选项的操作，显示多个播放速度选项；检测到用于在多个播放速度选项中选择目标播放速度选项的选择操作，确定所述目标播放速度选项对应的播放速度。
应理解，电子设备可以为用户提供目标对象的播放速度的多个选项，用户通过多个选项选择速度，为用户提供一个选择机会，提升用户体验。
在一种可能的设计中，当所述第二目标对象播放完毕时，停止播放所述视频文件；或者当所述第二目标对象播放完毕时，显示所述第二目标对象的最后一帧画面，继续播放所述视频文件的其它对象。
应理解，当目标对象播放完毕时，停止视频文件的播放，或者目标对象播放完毕时，停留到目标对象的最后一帧画面，其它对象继续播放。通过这种方式，用户可以快速观看视频文件中的用户感兴趣对象，提升视频播放的趣味性，提升用户体验。
在一种可能的设计中，电子设备在所述播放所述视频文件之前，从所述视频文件的N帧原始图像中每隔M帧抽取一帧原始图像，从抽取出的原始图像中提取K帧包含第一目标对象的图像；其中；N为大于等于2的整数；M是大于等于1小于N的整数，K是大于等于1小于N的整数；所述第一目标对象是抽取出的原始图像上的至少一个对象；将所述N帧原始图像中的所述第一目标对象使用背景覆盖，使得使用背景覆盖后的所述N帧原始图像中不包括所述第一目标对象；将提取出的所述K帧包含第一目标对象的图像和使用背景覆盖后的N帧原始图像中的K帧原始图像对应融合，得到K帧新图像；其中，使用背景覆盖后 的N帧原始图像中的K帧原始图像是连续的图像；将所述K帧新图像和剩余的N-K帧使用背景覆盖后的原始图像合成第一目标视频文件；所述电子设备播放所述视频文件，包括：播放所述第一目标视频文件。
应理解，以视频文件包括11帧原始图像为例，电子设备从11帧原始图像中每隔4帧图像抽取一帧原始图像，共抽取出3帧原始图像(即抽取出第1帧原始图像、第5帧原始图像和第9帧原始图像)。示例性的，手机100抽取图像时，可以从第1帧开始抽取，也可以从第2帧开始抽取等等，只要保证从第i帧开始抽取时，后续帧数足够即可。
电子设备从抽取出的原始图像中提取3帧包括第一目标对象的图像，然后将11帧原始图像中的第一目标对象使用背景覆盖(可以仅对11帧原始图像中包括第一目标对象的原始图像中的第一目标对象使用背景覆盖，对于不包含第一目标对象的原始图像可以不作背景覆盖处理)，使得使用背景覆盖之后的图像上不包括第一目标对象。应理解：本文中对于任一帧原始图像的第一目标对象，使用背景覆盖的时候，该背景可以采用原始图像上的背景，也可以是通用的背景，此处不做限定。
电子设备将提取出的3帧包含第一目标对象的图像和使用背景覆盖之后的11帧原始图像中的3帧原始图像对应融合，得到3帧新图像。其中，使用背景覆盖之后的11帧原始图像中的3帧原始图像是连续的，比如可以是使用背景覆盖之后的11帧原始图像中的前3帧图像。
电子设备将3帧新图像和剩余的8帧使用背景覆盖之后的图像合成第一目标视频文件，当该第一目标视频文件被播放时，第一目标对象快速播放。因此，电子设备可以根据视频文件的N帧原始图像，经过一系列的处理步骤，合成新的视频，然后播放新视频，在新视频的播放过程中，第一目标对象快速播放。
在一种可能的设计中，电子设备在所述继续播放所述视频文件之前，还可以从所述视频文件的N帧原始图像中每隔P帧抽取一帧原始图像，从抽取出的原始图像中提取Q帧包含第二目标对象的图像；其中；N为大于等于2的整数；P是大于等于1小于N的整数，Q是大于等于1小于N的整数；所述第一目标对象是抽取出的原始图像上的至少一个对象；将所述N帧原始图像中的所述第二目标对象使用背景覆盖，使得使用背景覆盖后的所述N帧原始图像中不包括所述第二目标对象；将提取出的所述Q帧包含第二目标对象的图像和使用背景覆盖后的N帧原始图像中的Q帧原始图像对应融合，得到Q帧新图像；其中，使用背景覆盖后的N帧原始图像中的Q帧原始图像是连续的图像；将所述Q帧新图像和剩余的N-Q帧使用背景覆盖后的原始图像合成第二目标视频文件；所述继续播放所述视频文件，具体为：播放所述第二目标视频文件。
应理解，以视频文件包括11帧原始图像为例，电子设备从11帧原始图像中每隔4帧图像抽取一帧图像，共抽取出3帧原始图像(即抽取出第1帧原始图像、第5帧原始图像和第9帧原始图像)。示例性的，手机100抽取图像时，可以从第1帧开始抽取，也可以从第2帧开始抽取等等，只要保证从第i帧开始抽取时，后续帧数足够即可。
电子设备从抽取出的原始图像中提取3帧包括第二目标对象的图像，然后将11帧原始图像中的第二目标对象使用背景覆盖(可以仅对11帧原始图像中包括第二目标对象的原始图像中的第二目标对象使用背景覆盖，对于不包含第二目标对象的原始图像可以不处理)，使得使用背景覆盖之后的图像上不包括第二目标对象。
电子设备将提取出的3帧包含第二目标对象的图像和使用背景覆盖之后的11帧原始图像中的3帧原始图像对应融合，得到3帧新图像。其中，使用背景覆盖之后的11帧原始图像 中的3帧原始图像是连续的，比如可以是使用背景覆盖之后的11帧原始图像中的前3帧图像。
电子设备将3帧新图像和剩余的8帧使用背景覆盖之后的图像合成第二目标视频文件，当该第二目标视频文件被播放时，第二目标对象快速播放。因此，电子设备可以根据视频文件的N帧原始图像，经过一系列的处理步骤，合成新的视频，然后播放新视频，在新视频的播放过程中，第二目标对象快速播放。也就是说，电子设备正在播放一视频文件时，若检测到目标对象切换的操作时，可以对视频文件中的所有图像进行处理，得到新视频，然后播放新视频，新视频的播放过程中，切换后的目标对象快速播放。
在一种可能的设计中，电子设备在所述继续播放所述视频文件之前，还可以从所述视频文件当前播放的图像的后续W帧原始图像中每隔P帧抽取一帧原始图像，从抽取出的原始图像中提取Q帧包含第二目标对象的图像；其中；W为大于等于2的整数；P是大于等于1小于W的整数，Q是大于等于1小于W的整数；所述第二目标对象是抽取出的原始图像上的至少一个对象；将所述W帧原始图像中的所述第二目标对象使用背景覆盖，使得使用背景覆盖后的所述W帧原始图像中不包括所述第二目标对象；将提取出的所述Q帧包含第二目标对象的图像和使用背景覆盖后的W帧原始图像中的Q帧原始图像对应融合，得到Q帧新图像；其中，使用背景覆盖后的W帧原始图像中的Q帧原始图像是连续的图像；将所述Q帧新图像和剩余的N-Q帧使用背景覆盖后的原始图像合成第二目标视频文件；所述继续播放所述视频文件，包括：播放所述第二目标视频文件。
应理解，电子设备在播放一视频文件，该视频文件包括11帧原始图像，该视频文件中第一目标对象在快速播放。假设电子设备检测到用于切换目标对象的操作时，正播放第3帧原始图像，则电子设备可以对视频文件中当前帧图像+后续未播放的图像(即第3帧原始图像到第11帧原始图像)进行处理，或者，仅对后续帧图像(即第4帧原始图像到第11帧原始图像)进行处理。
以电子设备仅对后续未播放的图像为例，电子设备可以从第4帧图像开始，进行抽帧、提取目标对象等处理，得到新视频，然后播放新视频，新视频的播放过程中，切换后的目标对象快速播放。
应理解，电子设备可以判断后续帧图像是否足够，若不够，电子设备可以从第1帧开始抽取。举例来说，视频文件包括11帧原始图像，当电子设备播放到第10帧时，检测到切换目标对象的操作，但后续帧只剩下1帧，则手机100可以从第1帧开始从抽取。
第二方面还提供一种视频处理方法，该方法可以由具有显示屏的电子设备(比如手机、ipad、笔记本电脑等)执行，该方法包括：响应于所述第一操作，播放所述视频文件，播放界面中处于第一区域中的第一内容的播放速度大于第二区域中的第二内容的播放速度；所述第二区域是播放界面中所述第一区域以外的其它区域；所述第一内容和所述第二内容属于所述视频文件中的播放内容；检测到用于切换快速播放区域的第二操作；响应于所述第二操作，继续播放所述视频文件，在继续播放所述视频文件的过程中，播放界面中处于第三区域中的第三内容的播放速度大于第四区域中第四内容的播放速度；所述第四区域是播放界面中所述第三区域以外的其它区域，所述第三内容和所述第四内容属于所述视频文件中的播放内容。
应理解，电子设备播放视频文件时，视频文件中的第一区域(或者称为目标区域)中的内容可以快速播放，而且在视频文件播放的过程中，第一区域可以切换。比如，当前，视频文件中的一个区域中的内容快速播放，其它区域内的内容正常播放，当切换区 域之后，该视频文件中的另一个区域内的内容快速播放，其它区域内的内容正常播放。通过这种方式，视频文件中某个区域内的内容可以快速呈现给用户，提升视频播放的趣味性，提升用户体验。

第四方面还提供一种视频处理方法，应用于具有摄像头和显示屏的电子设备，所述方法包括：检测到用于启动所述摄像头的第一操作；响应于所述第一操作，所述显示屏显示所述相机应用的取景界面，所述取景界面中包括预览图像，所述预览图像中包括至少一个对象；响应于第二操作，所述摄像头采集的N帧原始图像；N为大于等于2的整数；从所述N帧原始图像中每隔M帧抽取一帧原始图像，抽取出K帧原始图像；M为大于等于1小于N的整数，K为大于等于1小于N的整数；从抽取出的每帧原始图像中提取第一图像，共得到K帧第一图像；第一图像是抽取出的每帧原始图像上的第一区域内的图像；将所述N帧原始图像中每帧原始中的第一区域的第一图像使用背景覆盖，使得使用背景覆盖后的所述N帧原始图像中每帧原始图像上不包括所述第一图像；将所述K帧第一图像填充在使用背景覆盖后的N帧原始图像中的K帧原始图像上的所述第一区域，得到K帧新图像；其中，所述使用背景覆盖后的N帧原始图像中的K帧原始图像是连续的；将所述K帧新图像和剩余的N-K帧使用背景覆盖后的原始图像合成目标视频文件。
应理解，电子设备在录制视频的过程中，采集11帧原始图像后，从11帧原始图像中每隔4帧图像抽取一帧图像，共抽取出3帧原始图像，(即抽取出第1帧原始图像、第5帧原始图像和第9帧原始图像)。示例性的，手机100抽取图像时，可以从第1帧开始抽取，也可以从第2帧开始抽取等等，只要保证从第i帧开始抽取时，后续帧数足够即可。
电子设备从抽取出的每帧原始图像中提取第一图像(即每帧原始图像上的第一区域内的内容)，然后将11帧原始图像中每帧原始图像上的第一图像使用背景覆盖，使得11帧原始图像上不包括第一图像。
电子设备将提取出的3帧第一图像和使用背景覆盖之后的11帧原始图像中的3帧原始图像对应融合，得到3帧新图像。其中，使用背景覆盖之后的11帧原始图像中的3帧原始图像是连续的，比如可以是使用背景覆盖之后的11帧原始图像中的前3帧图像。
电子设备将3帧新图像和剩余的8帧使用背景覆盖之后的图像合成目标视频文件。当该目标视频文件被播放时，第一区域内的内容快速播放。电子设备通过该方式录制得到的视频文件，是经过特殊处理的视频文件，当该视频文件在播放时，第一区域的内容可以快速播放。通过这种方式，有助于提升视频录制的趣味性，提升用户体验。

在一种可能的设计中，所述第一区域为所述电子设备根据用户在所述预览图像上的选定操作，确定的区域，包括：检测到作用在所述预览图像上的至少一个圈选操作，确定每个圈选操作所围成的区域为所述第一区域。
应理解，用户可以取景界面中的预览图像上圈选一个区域，当电子设备录制视频文件之后，该视频文件在播放时，圈选的区域的内容可以快速播放。通过这种方式，有助于提升视频录制的趣味性，提升用户体验。
在一种可能的设计中，电子设备保存所述目标视频文件，所述目标视频文件的封面上显示标识，所述标识用于指示所述目标视频文件中第一区域播放速度大于其它区域的播放速度，所述其它区域是所述目标视频文件中除所述第一区域之外的区域。

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描述。
以下，对本申请实施例中的部分用语进行解释说明，以便于本领域技术人员理解。
本申请实施例涉及的应用程序(application，简称app)，为能够实现某项或多项特定功能的软件程序。通常，移动设备中可以安装多个应用程序。比如，相机应用、短信应用、邮箱应用、微信(WeChat)、WhatsApp Messenger、连我(Line)、照片分享(instagram)、Kakao Talk、钉钉等。下文中提到的应用程序，可以是移动设备出厂时已安装的应用程序，也可以是用户在使用移动设备的过程中从网络下载或其他移动设备获取的应用程序。需要说明的是，本申请实施例提供的视频处理方法应用于任何能够播放视频的应用程序中。
本申请实施例涉及的视频播放帧率，即每秒播放图像的帧数，单位是每秒帧数(frames per second，fps)。通常，视频由多帧图像构成，视频播放是将视频中的多帧图像连续的切换，每帧图像上的内容不同，以呈现出画面动图播放的过程。当图像的切换速度太慢时，会呈现出现画面不流畅，存在跳跃感，画面“闪烁”的感受。因此，视频的正常播放帧率与人的视觉反映时间相关。比如，正常播放帧率设置为24fps时，即每秒切换24帧图像时，在人眼看来已经是连续的动画了。目前，移动设备的视频播放帧率通常设置在25fps～30fps区间内。
本申请实施例涉及的图像采集帧率，即采集图像的速度，即每秒采集多少帧图像，以帧/秒为单位。通常，播放帧率小于等于图像采集帧率。比如，终端设备采集图像的帧率为60fps，播放帧率为30fps。
本申请实施例涉及的正常播放、快速播放，慢速播放。这三种播放速度是相对而言的。在本申请实施例中，正常播放、快速播放和慢速播放都是以相同的视频播放帧率(比如都是30fps)播放图像的，但是，对于同一视频文件来说，正常播放、快速播放和慢速播放所播放的图像的总帧数不同。通常，对于同一个视频文件，正常播放时，播放的图像的总帧数大于快速播放时播放的图像的总帧数，小于慢速播放时播放的图像的总帧数。
下面通过举例来介绍。
示例一，以移动终端是手机为例，手机从中存储有一个视频文件(比如手机从网络 侧下载的视频文件，或者接收其它设备发送的视频文件，或者手机已录制好的视频文件)。通常，手机播放视频文件时，将视频文件中的图像一帧一帧播放的，且是以正常播放速度(比如30fps)播放的。
请参见图2A所示，为本申请实施例提供的对于同一视频文件，快速播放和正常播放的示意图。假设该视频文件包括1200帧图像，正常播放帧率是30fps，正常播放时，不提取部分图像，即播放完1200帧图像，需要时长为40s。那么快速播放可以是从1200帧图像中每4帧图像提取一帧图像，得到300帧图像，只播放提取出的300帧图像，因为播放速度仍然是30fps，即快速播放时需要时长为10s(快速播放时的播放时长是正常播放所需时长的1/4)。
由此可见，手机都是以30pfs播放图像的，但是快速播放时，手机只播放了抽取出的300帧图像，正常播放时手机播放了1200帧图像，所以快速播放时播放的图像总帧数小于正常播放时播放的图像总帧数。
在示例一中，介绍手机已经获得视频文件，播放视频文件时，快速播放和正常播放的不同之处。
应理解，在示例一中，比如手机从网络侧下载的视频文件，该视频文件中包含的图像帧数已确定(比如1200帧)。通常，手机正常播放视频文件时，是从第一帧开始依次播放视频文件中的每一帧图像，直到播放完最后一帧图像，以图2A为例，正常播放是依次播放1200帧图像。因此，对于已经下载的视频文件，手机无法做到慢速播放，因为慢速播放需要播放更多的图像，但是由于视频中的图像帧数已确定，无法做到播放更多的图像。但是，手机可以按照图2A所示的方式快速播放，即从视频文件的图像中抽取部分图像，只播放抽取出的部分图像，实现快速播放。
当然，在另一些实施例中，对于已经下载的视频文件，手机也可以按照图2B所示的方式，实现快速、慢速和正常播放。请参见图2B所示，假设一个视频文件包括1200帧图像，且正常播放的速度为30fps。正常播放时可以每2帧图像提取一帧图像，提取出600帧图像，正常播放时仅播放提取出的600帧图像，需要时长为20s。慢速播放可以不提取部分图像，而是完全部分1200帧图像，则慢速播放时，需要时长为40s(时长是正常播放所需时长的2倍)。快速播放可以是每4帧图像提取一帧图像，提取出300帧图像，则快速播放时，需要时长为10s(时长是正常播放所需时长的1/2)。在这个实施例中，手机可以正常播放速度并不是将1200帧图像一帧一帧播放的，而是每2帧播一帧，这样的话，可以做到慢速播放，也可以做到快速播放。在这个实施例中，手机从网络侧下载一段视频之后，可以按照图2B所示的方式呈现慢速、快速、正常播放。
在上面的例子中，是以手机已经获取一个视频文件，播放这个视频文件为例，介绍正常、快速、慢速播放的区别，下面从另一个角度(手机录制视频文件的角度)，正常、快速、慢速播放的区别。
示例二：以移动终端是手机为例，且以手机录制视频的过程为例。通常，手机录制视频时，正常图像采集帧率等于正常播放帧率(比如都是30fps)。
举例来说，手机以30fps采集图像，且录制1s，则手机拍摄得到的视频有30帧，以30fps播放该视频时可以播放1s。这种方式为正常播放。
再例如，手机以高帧率(比如60fps)采集图像，录制1s，拍摄得到60帧图像，手机以30fps播放该视频时，播放2s，即慢速播放。
再例如，手机以低帧率(比如15fps)采集图像，录制1s，拍摄得到15帧图像，手机以30fps播放该视频时，播放0.5s，即快速播放。
通过上面的示例二可知，手机是以30fps播放视频的，但是由于录制的视频文件时，图像采集帧率不同，所以相同时间内录制的视频文件包含的图像的帧数不同，所以手机播放录制的视频文件时，需要的时长不同，所以呈现出不同的播放效果(快速或者慢速)。
应理解，上面的示例二中，手机录制视频时的图像采集帧率与快速播放或者慢速播放相关，这部分内容将在后文介绍。
通过上面的例子可知，无论快速播放、慢速播放或者正常播放，都是相同的播放帧率，但是快速播放的情况下，终端设备需要播放的图像帧数小于慢速播放(或者正常播放)情况下要播放的图像帧数，所以对比来看，同一个视频文件，快速播放比慢速播放(或者正常播放)需要的时间较短，给人呈现快速播放的效果。
本申请实施例涉及的视频文件，可以是移动终端从网络侧下载的视频文件，也可以是移动终端自身录制的视频文件，还可以是网络在线加载的视频文件等。本申请实施例提供的视频处理方法可以适用于各种格式的视频文件，比如，rmvb，avi，MP4等等格式的视频文件。而且，本申请实施例提供的视频处理方法可以适用于通过任何视频编码方式获得的视频，比如动态图像专家组(moving picture experts group，MPEG)等视频编码方式。
本申请实施例涉及的多个，是指大于或等于两个。
需要说明的是，本文中术语“和/或”，仅仅是一种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这三种情况。另外，本文中字符“/”，如无特殊说明，一般表示前后关联对象是一种“或”的关系。且在本申请实施例的描述中，“第一”、“第二”等词汇，仅用于区分描述的目的，而不能理解为指示或暗示相对重要性，也不能理解为指示或暗示顺序。
以下介绍移动设备、用于这样的移动设备的图形用户界面(graphical user interface，GUI)、和用于使用这样的移动设备的实施例。在本申请一些实施例中，移动设备可以是手机、平板电脑、笔记本计算机或具备无线通讯功能的可穿戴设备(如智能手表或智能眼镜等)等。该移动设备包含能够采集图像或视频的图像采集模块，以及能够运行本申请实施例提供的图像处理算法的器件(比如应用处理器，或，图像处理器，或，其他处理器)。该移动设备的示例性实施例包括但不限于搭载
Figure PCTCN2019076360-appb-000001
或者其它操作系统的设备。上述移动设备也可以是其它便携式设备，只要能够采集图像或视频，并运行本申请实施例提供的图像处理算法即可。还应当理解的是，在本申请其他一些实施例中，上述移动设备也可以不是便携式移动设备，而是能够采集图像或视频，并运行本申请实施例提供的图像处理算法的台式计算机。
当然，在本申请另一些实施例中，移动设备也可以无需具有图像采集功能，只需具有运行本申请实施例提供的图像处理算法的能力即可，可以使用本申请实施例提供的图像处理算法处理其它设备发送的图像。在下文中，以移动设备自己采集图像，并运行图像处理算法为例。
以移动设备是手机为例，图3示出了手机100的结构示意图。

可以理解的是，本申请实施例示意的结构并不构成对手机100的具体限定。在本申请另一些实施例中，手机100可以包括比图示更多或更少的部件，或者组合某些部件，或者拆分某些部件，或者不同的部件布置。图示的部件可以以硬件，软件或软件和硬件的组合实现。
下面对图3示出的手机100中的部件进行介绍。
处理器110可以包括一个或多个处理单元，例如：处理器110可以包括应用处理器(application processor，AP)，调制解调处理器，图形处理器(graphics processing unit，GPU)，图像信号处理器(image signal processor，ISP)，控制器，存储器，视频编解码器，数字信号处理器(digital signal processor，DSP)，基带处理器，和/或神经网络处理器(neural-network processing unit，NPU)等。其中，不同的处理单元可以是独立的器件，也可以集成在一个或多个处理器中。其中，控制器可以是手机100的神经中枢和指挥中心。控制器可以根据指令操作码和时序信号，产生操作控制信号，完成取指令和执行指令的控制。
处理器110中还可以设置存储器，用于存储指令和数据。在一些实施例中，处理器110中的存储器为高速缓冲存储器。该存储器可以保存处理器110刚用过或循环使用的指令或数据。如果处理器110需要再次使用该指令或数据，可从所述存储器中直接调用。避免了重复存取，减少了处理器110的等待时间，因而提高了系统的效率。
其中，处理器110可以运行本申请实施例提供的视频播放算法的代码，实现视频中用户感兴趣的内容快速播放，用户不感兴趣的内容慢速播放。以处理器110集成GPU为例，GPU可以运行视频播放算法的代码。
内部存储器121可以用于存储计算机可执行程序代码，所述可执行程序代码包括指令。处理器110通过运行存储在内部存储器121的指令，从而执行手机100的各种功能应用以及数据处理。内部存储器121可以包括存储程序区和存储数据区。其中，存储程序区可存储操作系统，至少一个功能所需的应用程序(比如声音播放功能，图像播放功能等)等。存储数据区可存储手机100使用过程中所创建的数据(比如相机应用拍摄的图像，视频)等。
内部存储器121还可以用于存储本申请实施例提供的视频播放算法的代码。处理器100访问并运行内部存储器121中的所述代码，实现相关功能。当然，本申请实施例提供的视频播放算法的代码也可以存储在处理器110自身的内存中(比如，处理器110是CPU时，本申请实施例提供的视频播放算法的代码可以存储在CPU缓存中)。
其中，内部存储器121可以包括高速随机存取存储器，还可以包括非易失性存储器，例如至少一个磁盘存储器件，闪存器件，通用闪存存储器(universal flash storage，UFS)等。
下面介绍传感器模块180的功能。
压力传感器180A用于感受压力信号，可以将压力信号转换成电信号。在一些实施例中，压力传感器180A可以设置于显示屏194。
距离传感器180F，用于测量距离。手机100可以通过红外或激光测量距离。在一些 实施例中，拍摄场景，手机100可以利用距离传感器180F测距以实现快速对焦。在另一些实施例中，手机100还可以利用距离传感器180F检测是否有人或物体靠近。
接近光传感器180G可以包括例如发光二极管(LED)和光检测器，例如光电二极管。发光二极管可以是红外发光二极管。手机100通过发光二极管向外发射红外光。手机100使用光电二极管检测来自附近物体的红外反射光。当检测到充分的反射光时，可以确定手机100附近有物体。当检测到不充分的反射光时，手机100可以确定手机100附近没有物体。手机100可以利用接近光传感器180G检测用户手持手机100贴近耳朵通话，以便自动熄灭屏幕达到省电的目的。接近光传感器180G也可用于皮套模式，口袋模式自动解锁与锁屏。
指纹传感器180H用于采集指纹。手机100可以利用采集的指纹特性实现指纹解锁，访问应用锁，指纹拍照，指纹接听来电等。
触摸传感器180K，也称“触控面板”。触摸传感器180K可以设置于显示屏194，由触摸传感器180K与显示屏194组成触摸屏，也称“触控屏”。触摸传感器180K用于检测作用于其上或附近的触摸操作。触摸传感器180K可以将检测到的触摸操作传递给应用处理器，以确定触摸事件类型。可以通过显示屏194提供与触摸操作相关的视觉输出。在另一些实施例中，触摸传感器180K也可以设置于手机100的表面，与显示屏194所处的位置不同。
触摸传感器180K可以用于检测用户的触摸操作。比如，手机100显示主界面，主界面中包括多个应用程序的图标(比如，微信、相机、电话、备忘录等)。触摸传感器180K检测到用户在主界面中的触摸操作后，将触摸操作发送给处理器110。处理器110将基于该触摸操作确定该触摸操作的触摸位置，并确定该触摸位置对应的图标。假设处理器110确定该触摸操作对应的图标是相机应用的图标，则手机100启动相机应用。
显示屏194用于显示图像，视频等。显示屏194包括显示面板。显示面板可以采用液晶显示屏(liquid crystal display，LCD)，有机发光二极管(organic light-emitting diode，OLED)，有源矩阵有机发光二极体或主动矩阵有机发光二极体(active-matrix organic light emitting diode的，AMOLED)，柔性发光二极管(flex light-emitting diode，FLED)，Miniled，MicroLed，Micro-oLed，量子点发光二极管(quantum dot light emitting diodes，QLED)等。在一些实施例中，手机100可以包括1个或N个显示屏194，N为大于1的正整数。
另外，手机100可以通过音频模块191(扬声器，受话器，麦克风，耳机接口)，以及处理器110等实现音频功能。例如音乐播放，录音等。手机100可以接收按键190输入，产生与手机100的用户设置以及功能控制有关的键信号输入。手机100中的SIM卡接口195用于连接SIM卡。SIM卡可以通过插入SIM卡接口195，或从SIM卡接口195拔出，实现和手机100的接触和分离。
尽管图3未示出，手机100还可以包括摄像头，例如前置摄像头、后置摄像头；还可以包括马达，用于产生振动提示(比如来电振动提示)；还可以包括指示器比如指示灯，用于指示充电状态，电量变化，也可以用于指示消息，未接来电，通知等。
如前述内容可知，现有技术中，手机是对整个视频画面的快速或慢速呈现。本申请实施例提供的视频播放方式中，视频播放画面中不同区域(或不同对象)的播放方式可以不同。比如，视频播放画面中的区域A(或对象A)快速播放，而区域B(或对象B)慢速播放或正常速度。通过这种方式，能够实现比如视频中的精彩部分或者用户感兴趣 的部分可以慢速播放，将其他内容可以快速播放，有助于提升视频播放的趣味性，提升用户体验，吸引广大消费者。
为了便于理解，本申请以下实施例将以具有图3所示结构的手机为例，结合附图对本申请实施例提供的视频处理方法进行具体阐述。
图4中的(a)示出了手机100的一GUI，该GUI为手机的桌面401。当手机100检测到用户点击桌面401上的相册(或图库、照片)应用的图标402的操作后，可以启动相册应用，显示如图4中的(b)所示的另一GUI，该GUI中包括多个视频文件(图中以2个视频文件为例)。当手机100检测到用户点击视频404的操作后，显示如图4中的(c)所示的又一GUI，该GUI包括视频404的第一帧图像的预览界面405。通常，预览界面405中显示一个播放控件406，当该播放控件405被触发时，手机100开始播放视频404(比如从第一帧图像开始播放)。
在一些实施例中，在图4中的(c)所示的GUI中，当手机100检测到用户用于指示对视频404“智能播放”的操作后，手机100可以对视频404中不同对象以不同的播放速度播放。
为了帮助用户了解智能播放，手机100可以提供智能播放的相关信息。作为一种示例，请参见图5中的(a)所示，在预览界面405中包括播放选项控件501，当该播放选项控件501被触发时，手机100显示播放模式选择框502，该播放模式选择框502中包括普通播放选项503和智能播放选项504。
当手机100检测到普通播放选项503被触发时，手机100按照现有技术方式播放视频(比如，视频中每帧图像连续播放，每个对象播放速度相同)。当用户触发智能播放选项504时，手机100显示如图5中的(b)所示的界面。手机100显示详情控件505，完成控件506，以及提示信息“请选择目标对象”(后文介绍)。当用户触发详情控件505时，手机100显示如图5中的(c)所示的界面，即手机100提供智能播放模式的相关信息的示例，以帮助用户了解智能播放的功能。图5中的(c)仅是一种智能播放模式的简介的示例，并不是限定。
在一些实施例中，目标对象可以是用户指定的。比如，用户可以在图5中的(b)所示的界面中手动选择目标对象。下面介绍几种示例。
示例一，请参见图6中的(a)所示，手机100显示文字信息“请您点击画面中的目标对象”。当手机100检测到用户在第一帧图像中的点击操作后，基于该点击操作确定目标对象。假设用户点击第一帧图像中的天鹅，手机100确定天鹅是目标对象。
为了方便提示用户已选择的目标对象，手机100可以显示已选择的目标对象的标识信息。比如，请参见图6中的(a)中的标识信息601。需要说明的是，用户点击一个目标对象，则标识信息601中包括一个目标对象的标识信息。当用户继续点击其它目标对象时，标识信息601中新增其它目标的标识信息。请对比图6中的(a)和(b)可知，当用户只点击天鹅时，标识信息601中只包括黑天鹤，当用户继续点击鱼时，标识信息601中新增鱼。
当然，当用户选择多个目标对象后，若想要删除一个目标对象，可以再次点击该目标对象(单击或者双击)，标识信息601中可以删除该目标对象的标识信息。
当手机100检测到确定按钮602的操作时，手机100确定标识信息601中包括的对象是目标对象。
示例二，请参见图7中的(a)所示，手机100显示选择框以及提示信息“请您移动选择框以选择目标对象”。手机100将选择框中包含的对象，确定为目标对象。该选择框的位置可以移动，大小可以变化。
具体而言，当选择框包括一个对象的部分区域(比如图6中选择框包括天鹅的部分身体)时，手机100可以确定该对象处于选择框内的区域的面积占该对象的整个面积的比例，若比例大于预设比例，则确定选择框包括这个对象。
当然，为了方便提示用户已选择的目标对象，手机100可以显示已选择的目标对象的标识信息701。比如，当手机100检测到选择框被放大，则选择框中包括的对象增多，标识信息701中包括的对象增多。类似的，用户也可以删除目标对象(比如缩小选择框的大小)。当手机100检测到确定按钮702的操作时，手机100确定标识信息701中包括的对象是目标对象。
示例三，请参见图8中的(a)所示，手机100识别第一帧图像中所包含的对象，并显示识别出的每个对象的编号。手机100检测到用户选择某个编号的操作时，手机100确定该编号对应的对象是目标对象。
当然，手机100可以显示已选择的目标对象的标识信息801。比如，当手机100检测到用户选择编号1的对象之后，标识信息801包括编号1、当用户继续选择编号2的对象之后，标识信息802中增加编号2。类似的，用户也可以删除目标对象(比如再次点击编号1的对象，标识信息801中删除编号1)。当手机100检测到确定按钮802的操作时，手机100确定标识信息801中包括的编号对应的对象是目标对象。
示例四，请参见图9中的(a)所示，手机100检测到用户在第一帧图像上的画圈操作后，确定该画圈操作的轨迹所围成的区域内的对象为目标对象。当然，用户画圈操作的轨迹所围成的区域的大小，显示位置可以变化。比如，请对比图9中的(a)和(b)，当画圈操作形的轨迹所围成区域被放大，该区域内的对象增多，标识信息901中增加鱼。当然，用户也可以删除目标对象(比如缩小选择框的大小)，标识信息901中删除移出选择框的目标对象的标识信息。
当然，请参见图9中的(c)所示，用户也可以在第一帧图像上，进行多次画圈操作，每个画圈操作所围区域的对象都是目标对象。用户也可以删除目标对象。比如，长按某个画的圈，删除该圈，请参见图9中的(d)所示。
在另一些实施例中，目标对象还可以是手机100自动选择的。举例来说，手机100按照预设策略识别第一帧图像中的目标对象。比如，手机100中预设有物体类型“人物”、“动物”、“建筑物”等。手机100识别第一帧图像中一个或多个对象属于预设的物体类型，则手机100确定一个或多个对象是目标对象。手机100中预设的物体类型可以是手机100出厂之前设置好的，也可以是用户自定义的。
应理解，第一帧图像上包含的物体种类可能较多。因此，手机100可以设置有多个物体类型的优先级顺序：人物高于动物，动物高于建筑。示例性的，若第一帧图像上包括人物、动物和建筑，则优先级最高的物体类型人物为目标对象，或者优先级最高的两个物体类型人物和动物为目标对象。再示例性的，若第一帧图像上不包括人物，而包括动物和其他物体，则原始图像上包括的优先级最高的动物为目标对象。
当然，手机100还可以有其它方式选择目标对象。比如，第一帧图像中处于中间位置的对象确定为目标对象，第一帧图像中的人物默认为目标对象，第一帧图像所占面积最 大的对象作为目标对象等等。
当手机100确定目标对象之后，还可以确定目标对象的播放速度。
在一些实施例中，请参见图10所示，手机100显示已选择的目标对象，以及速度播放选项，包括：2倍速选项，1.5倍速选项，0.5倍速选项。假设用户触发2倍速选项，当手机100检测到触发完成控件1001的操作时，手机100开始播放视频404，其中，目标对象以2倍速播放，其它对象以正常速度播放。
在另一些实施例，手机100确定出的目标对象有多个时，可以确定每个目标对象的播放速度。比如，请参见图11所示，手机100显示两个目标对象各自的播放速度选项。假设用户选择天鹅的播放速度是2倍速，鱼的播放速度是0.5倍速，当手机100检测到触发完成控件1101的操作时，开始播放视频404，其中，天鹅快速播放，鱼慢速播放。
在另一些实施例中，手机100还可以确定除去目标对象之外的背景的播放速度。比如，请参见图12A所示，手机100还显示背景(除去天鹅和鱼之外的其它对象)的播放速度选项。假设用户选择背景的播放速度是1.5倍速，手机100以1.5倍速播放背景。
当然，在实际应用中，手机100还可以有其它方式确定目标对象的播放速度，本申请实施例不限定。
在本申请另一些实施例中，手机100播放视频时，无需用户选择目的对象，也无需用户选择播放速度。比如，手机100进入智能播放模式后，手机100自动识别视频文件中的目标对象，然后将目标对象以默认的速度(比如2倍速)播放。再比如，手机100进入智能播放模式时，播放视频，但是视频播放界面中包括一窗口，该窗口中的内容以默认速度(比如2倍速)播放，窗口外的内容以正常速度播放。
在以上的实施例(图4-图10)中，是以视频404的第一帧图像为例的，即目标对象的选择、播放速度的选择都是针对视频404的第一帧图像的。在实际应用中，若手机100当前正在播放一个视频，若手机100检测到暂停播放的控件时，手机100暂停到当前播放的一帧图像。用户可以在当前帧图像上选择目标对象、以及目标对象的播放速度等操作。手机100从当前帧图像开始到播放后续帧图像，在后续帧图像的播放过程中，不同对象以不同播放速度显示。
在一些实施例中，视频文件的播放过程中，还可以切换目标对象。比如，请参见图12B(a)所示，手机100当前选择的目标对象是天鹅(比如用户指定的天鹅，或者手机100自动确定的天鹅)，所以手机100播放视频的过程中，天鹅快速播放，在播放界面中显示用于指示切换目标对象的控件1203，当该控件1203被触发时，手机100将目标对象由天鹅切换为鱼，请参见图12B(b)所示。在后续播放过程中，手机100快速播放鱼；或者，从头开始播放视频文件，在从头播放的过程中，鱼被快速播放。
应理解，手机100检测到用户触发控件1203的操作时，可以自动确定其他目标对象，以替换当前的目标对象，比如手机100从视频文件中的多个对象中选择与当前的目标对象不同的对象。
当然，手机100也可以在检测到用户触发控件1203的操作时，暂停播放视频文件，用户可以在暂停的画面中选择新的目标对象(点击、圈选等)；或者，手机100暂停播放视频文件时，若暂停画面中没有用户要选择的目标对象时，用户可以将暂停画面中切换到其它画面，在其它画面中选择新的目标对象。
当然，图12B中还可以包括添加目标对象的控件(图中未示出)，当该控件被触发时， 手机100增加目标对象的数量；或者，图12B中还可以包括减少目标对象的控件(图中未示出)，当该控件被触发时，手机100减少目标对象的数量。
在另一些实施例中，手机100无需确定目标对象，而是确定目标区域，视频播放过程中，播放界面中处于目标区域内的内容快速播放。具体而言，目标区域可以是用户指定的，比如在视频文件的一帧图像上选择的区域；或者目标区域是手机100自动确定的区域，比如目标对象较多的区域或面积较大的目标对象所在的区域等；或者，目标区域是预先设置好。
示例性的，手机100在播放视频文件的过程中，还可以切换目标区域。请参见图12C(a)所示，手机100在播放视频文件的过程中，矩形框(第一区域)中的内容快速播放，当手机100检测到用于指示切换目标区域的控件1205的操作时，手机100继续播放视频，在继续播放视频文件的过程中，第三区域中的内容快速播放；或者，当手机100检测到用于指示切换目标区域的控件1205的操作时，手机100从头播放视频文件，在从头播放视频文件的过程中，第三区域中的内容快速播放。
应理解，手机100检测到用户触发控件1205的操作时，可以自动确定新的目标区域；或者，手机100也可以在检测到用户触发控件1205的操作时，暂停播放视频文件，用户可以在暂停的画面中指定新的目标区域(比如圈选新的目标区域等)；或者，手机100暂停播放视频文件时，用户可以将暂停画面中切换到其它画面，在其它画面中指定新的目标区域。
当然，图12C中还可以包括增大目标区域的控件(图中未示出)，当该控件被触发时，手机100增加目标区域所占的面积；或者，图12C中还可以包括缩小目标区域的控件(图中未示出)，当该控件被触发时，手机100缩小目标区域所占的面积。
通过以上描述可知，本申请实施例提供的视频处理方法中，视频播放画面中不同区域(或不同对象)的播放方式可以不同。比如，视频播放画面中的区域A(或对象A)快速播放，而区域B(或对象B)慢速播放或正常速度。因此，这段视频的播放过程中，区域A(或对象A)以较慢的速度呈现给用户，而区域B(或对象B)以较快的速度呈现给用户。通过这种方式，能够实现视频播放画面中不同区域或对象以不同的播放速度呈现给用户，比如视频中的精彩部分或者用户感兴趣的部分可以慢速播放，将其他内容可以快速播放，有助于提升视频播放的趣味性，提升用户体验，吸引广大消费者。
下面以视频画面中目标对象以2倍速播放，其它对象正常播放为例，介绍手机100如何快速播放目标对象。
请参见图13所示，为本申请实施例提供的视频处理方法的流程的示意图。如图13所示，假设视频文件包括1200帧原图像，手机100确定目标对象。且目标对象以2倍速播放之后，从1200帧原图像中每2帧图像提取一帧图像，得到600帧原图像，然后从这600帧原图像中提取目标对象(比如将目标对象分割出来)，得到600帧目标对象图像(比如将分割出的目标对象作为单独的图像，即目标对象图像)。手机100可以将1200帧原图像中的目标对象使用背景覆盖，使得使用背景覆盖后的原图像中不包括目标对象。手机100将提取出的600帧目标对象图像和使用背景覆盖后的1200帧中前600帧图像对应融合，得到600帧新图像，然后将600帧新图像和剩余的600帧使用背景覆盖后的原图像合成一个新的视频文件，手机100在播放该新的视频文件时，呈现出目标对象快速播放，而其它对象正常播放的效果。
在一些实施例中，手机100还可以将目标对象图像和得到的新视频文件对应存储。比如，手机100将目标对象图像存在图库中，当手机100检测到用户打开图库中的该目标对象图像的操作时，该目标对象图像上显示一标记，当该标记被触发时，手机100打开与该目标对象对应存储的视频文件，在该视频文件中目标对象快速播放。
在另一些实施例中，以图13所示的实施例为例，手机100还可以将提取出的600帧目标对象图像和使用背景覆盖之后的1200帧原图像，对应存储。当手机100检测到用户指示该视频文件中的目标对象(用户指示的目标对象与存储的600帧目标对象图像中的目标对象相同)以2倍速播放时，将存储的600帧目标对象图像和使用背景覆盖后的1200帧原图像中的前600帧原图像对应融合，得到新视频，然后播放该视频。这个过程中，手机100无需执行从原图像中抽帧、提取目标对象图像的过程，只需执行融合过程即可，有助于提升效率。
当然，在另一些实施例中，当手机100再次检测到用户指示该视频文件中的目标对象以2倍速播放时，也可以仍然按照图13所示的流程，再次执行抽帧、提取目标对象图像、然后图像融合合成新视频等过程。
应理解，在图13所示的示例中，手机100是先抽取出600帧原图像，然后从600帧原图像中提取目标对象图像。当然，手机100可以先从1200帧图像中的每帧图像中提取目标对象图像，然后再从提出出的目标对象图像中抽帧(比如从1200个目标对象图像中抽取出600个目标对象图像)。因为，在实际应用中，1200帧图像中可能部分图像中没有目标对象，假设只有1000帧图像中有目标对象，那么手机100可以先从1000帧图像中提取目标对象图像，得到1000帧目标对象图像，然后从1000帧目标对象图像中抽出600帧目标对象图像。当然，手机100还可以有其它方式来提取目标对象，只要满足目标对象的帧数少于原图像的帧数即可，本申请实施例不限定。下文中，以手机100先抽取出部分原图像，然后从抽取出的原图像中提取目标对象图像为例。
请参见图14所示，为本申请实施例提供的视频处理方法的流程示意图，如图14所示，该方法的流程包括：
S1401：手机100获取待处理视频文件，所述视频文件包括N帧原图像，N为大于等于2的整数。
手机100可以拍摄得到视频文件(比如通过相机应用拍摄得到视频)，或者从网络侧下载视频文件(比如从爱艺奇、腾讯等客户端下载的视频文件)，或者从其它设备接收到的视频文件(比如手机100通过微信应用接收其它设备发送的视频)等等，本申请实施例不限定。
应理解，本申请实施例的视频处理方法，不仅可以适用于视频文件的播放，还可以应用在动图文件，或者利用应用程序合成的一组图片文件等的播放。
S1402：手机100确定视频文件中的目标帧原图像，所述目标帧原图像是所述N帧原图像中的一帧图像。
可选的，目标帧图像可以是待处理视频文件包含的多帧图像中的一帧图像。下面介绍手机100确定待播放视频文件中目标帧图像的几种方式。
作为一种示例，手机100并未播放该待处理视频文件时，手机100可以将视频文件的封面作为目标帧原图像。请参见图4中的(c)所示，手机100还未播放视频404时，则手机100确定视频404的封面就是目标帧原图像。
作为另一种示例，手机100当前正在播放待处理视频文件，若手机100检测到用户触发暂停播放的操作，则暂停播放该视频文件，暂停时显示的一帧图像可以作为目标帧原图像。
作为又一种示例，手机100暂停视频播放时，暂停时显示的一帧图像中可以显示一第一控件和第二控件，当第一控件被触发时，手机100切换到上一帧图像，当第二控件被触发时，手机100切到到下一帧图像，即用户可以通过这两个控件，切换图像来选择目标帧原图像。
作为另一种示例，手机100暂停视频播放时，手机100可以自动显示该视频文件中包含较多目标对象的一帧图像，该图像为目标帧原图像。
当然，目标帧图像的确定方式不限于上述列举的几种，在此不再一一列举。
S1403：手机100确定目标帧原图像中的目标对象，并确定目标对象的第一播放速度，所述第一播放速度大于所述待播放视频的正常播放速度，所述目标对象是所述当前帧图像中的至少一个对象。
关于手机100确定目标对象的过程，前文已经描述过程(用户指定目标对象或者手机100自动识别目标对象等)，在此不再重复赘述。
S1404：手机100基于第一播放速度，确定图像抽取帧数。
需要说明的是，由于第一播放速度是快速播放目标对象，所以手机100需要抽取出部分原图像。
作为一种示例，手机100中可以存储有播放速度和图像抽取帧数之间的对应关系，基于该对应关系，确定要抽取多少帧图像。请参见表1，为本申请实施例提供的播放速度与图像抽取帧数之间的对应关系的示例。
表1
播放速度 图像抽取帧数
2倍速度 每隔2帧抽取一帧图像
3倍速度 每隔3帧抽取一帧图像
4倍速度 每隔4帧抽取一帧图像
若用户选择以2倍速播放目标对象，手机100基于表1可以确定每隔2帧抽取一帧图像。
S1405：手机100按照确定出的图像抽取帧数从待处理视频文件的N帧原图像中抽取M帧原图像，M为大于等于1小于N的整数。
S1405的实现方式可以有多种，下文将列举几种。
方式一，手机100可以按照确定出的图像抽取帧数从待处理视频文件中的所有原图像中抽取部分图像。
举例来说，假设视频文件包括1200帧原图像，而目标帧原图像是视频文件的封面，且封面是第一帧原图像，若手机100确定每隔2帧抽取一帧，那么手机100从第一帧原图像开始每隔2帧抽取一帧。
方式二，若手机100暂停播放视频文件，且暂停时显示的一帧图像是目标帧原图像，则手机100可以从暂停时显示的图像开始，抽取图像，即无需从目标帧图像之前的原图像中抽取图像。举例来说，暂停时显示的是第200帧，若手机100确定每隔2帧抽取一帧时， 可以从第200帧开始每隔2帧抽取一帧。
S1406：手机100从抽取出的M帧原图像中提取K帧包含目标对象的图像，K为大于等于1小于N的整数。
可选的，手机100抽取的原图像中可能部分原图像中存在目标对象，部分原图像中不存在目标对象，对于不存在目标对象的原图像，手机100可以不进行目标对象的提取步骤。
可选的，手机100提取目标对象之后，可以将目标对象从图像中分割出来，这样的话，手机100将得到目标对象图像(将分割出的目标对象称为目标对象图像)。应理解，手机100从原图像中提取目标对象时，可以以目标对象的边缘轮廓提取目标对象，也可以是提取目标对象所在区域(该区域的面积可以大于目标对象的边缘轮廓所围区域的面积)。
S1407：手机100将视频文件中N帧原图像中的目标对象去除，得到处理后的N帧原图像，处理后的N帧原图像中没有目标对象。
在前面的步骤中，手机100从原图像中抽取部分原图像，并从抽取的原图像中提取目标对象，得到目标对象图像。手机100已得到目标对象图像，所以手机100可以将原图像中的目标对象去除。其中，去除目标对象的方式可以是使用背景覆盖。以一帧原图像为例，手机100可以使用这帧原图像中的背景覆盖这帧原图像中的目标对象，比如使用该帧原图像中目标对象所在区域以外的其它区域拷贝覆盖到目标对象所在的区域，即将目标对象所在区域的内容使用其他区域的内容来填充。当然，实际应用中，还可以有其它的去处目标对象的方式，本申请实施例不作限定。
应理解，部分原图像中可能不包括目标对象，所以手机100可以只对包含目标对象的原图像中的目标对象使用背景覆盖，对于不包含目标对象的原图像可以不作背景覆盖处理。
S1408：手机100将提取出的K帧目标对象图像和处理后的N帧原图像中的K帧原图像对应融合，得到K帧新图像；处理后的N帧原图像中的K帧原图像是连续的。
示例性的，因为处理后的原图像中没有目标对象。因此，目标对象图像和处理后的图像的融合方式可以有多种，比如将目标对象图像覆盖在处理后的原图像上的一个区域，得到一张新图像，其中，一个区域可以是原图像上的任意一个区域。其中，具体的融合算法可以是小波融合算法、比值(brovey)变换法等等，本申请实施例不限定。
示例性的，手机100可以将提取出的K帧目标对象图像和处理后的N帧原图像中的前K帧原图像对应融合。
S1409：手机100将K帧新图像，和剩余的处理后的N-K帧原图像合成新视频文件。
手机100得到新的视频文件之后，若该新的视频文件被播放，则目标对象快速播放。
下面举一个例子来介绍本申请实施例提供的视频处理过程。
请参见图15所示，为本申请实施例提供的一种视频处理方法的示例。如图15所示，假设视频文件共有11帧原图像，当前帧是第1帧原图像。手机100确定目标对象，且目标对象的播放速度为4倍速。手机100基于表1可知，从11帧图像中每隔4帧图像抽取一帧图像，即抽取第1、5、9帧原图像。
若抽取出的第1、5、9帧原图像中每帧原图像中均包含目标对象，则手机100从抽取出的3帧原图像中的每张原图像中分割出目标对象，得到目标对象1-3(应理解，这里的目标对象1-3是为了区分从不同帧原图像上分割出的同样的对象，不是指3个不同的对象)。其中，目标对象1是从第1帧图像上分割出的(即目标对象1是第1帧原图像上的 一个或多个对象)，目标对象2是从第5帧图像中分割出的(即目标对象2是第5帧原图像上的一个或多个对象)，目标对象3是从第9帧图像上分割出的(即目标对象3是第9帧原图像上的一个或多个对象)。
应理解，手机100得到目标对象1-3之后，可以将第1-11帧原图像中的目标对象去除(可以仅对11帧原图像中包括目标对象的原图像作去除目标对象处理，对于11帧原图像中不包括目标对象的原图像可以不作去除目标对象的处理)。示例性的，请继续参见图15所示，由于目标对象1是从第1帧原图像上分割出的，所以第1帧原图像上存在空白地方，手机100可以使用背景填充该空白区域(比如，手机100将第1帧原图像中非空白区域的内容填充到该空白区域)，然后手机100将背景填充后的图像和目标对象1融合得到一帧新图像，播放该新图像。当然，由于目标对象1是从第1帧原图像上分割出的，手机100也可以无需填充空白区域，可以将目标对象1填充到该空白地方，得到一帧新图像。
由于目标对象2是从第5帧原图像中提取出的，不是从第2帧原图像中提取出的。因此，手机100可以将第2帧原图像本身包括目标对象用背景覆盖(比如使用第2帧原图像中目标对象所在区域以外的其它区域拷贝覆盖到目标对象所在的区域，即将目标对象所在区域的内容使用其他区域的内容来填充)，然后将背景覆盖之后的第2帧原图像和目标对象2融合，得到一帧新图像，该新图像中只包括从第5帧原图像中提取的目标对象2，不包含第2帧原图像本身包括目标对象。
由于目标对象3是从第9帧原图像中提取出的，不是从第3帧原图像中提取出的。因此，手机100可以将第3帧原图像本身包括目标对象使用背景覆盖，然后将背景覆盖之后的第3帧原图像和目标对象3融合，得到一帧新图像，该新图像中只包括从第9帧原图像中提取的目标对象3，不包括第3帧原图像本身包括目标对象。
由此可见，本申请实施例中，手机100在播放第2帧原图像时，同步显示的是第5帧原图像中的目标对象2，在播放第3帧原图像时，同步显示的是第9帧原图像中的目标对象3。因此，手机100呈现出将目标对象以较快的速度播放，而背景正常播放的效果。
需要说明的是，图15所示的过程是以视频文件中目标对象如何快速播放为例的，如前世内容可知，本申请实施例中，视频文件的播放界面中目标区域内的内容也可以实现快速播放，其中，目标区域可以是预设的区域，也可以是用户指定的区域等。类似的，对于这种情况，手机100也可以按照图15所示的流程来处理，只需将图15所示的目标对象替换为目标区域内的图像即可，假设目标区域是矩形，那么目标区域内的图像是目标区域所围成的矩形图像，然后将该矩形图像作为目标对象图像进行处理即可。
以图12B(a)和图12B(b)为例，视频播放过程中，目标对象由天鹅切换成鱼，这个过程中，用户可以执行两次图15所示的过程。比如，在手机100确定目标对象是天鹅时，执行一次图15所示的流程，得到一个视频文件，播放该视频文件的过程中，天鹅被快速播放。
在播放到某一帧画面时，手机100检测到用户触发控件1203的操作时，手机100对所述某一帧画面的后续帧图像重新执行图15所示的流程，得到另一个视频文件，手机100播放该另一个视频文件的过程中鱼被快速播放；或者，手机100检测到用户触发控件1203的操作时，手机100对该视频文件的所有图像重新执行图15所示的流程，得到另一个视频文件，手机100播放该视频文件时，鱼被快速播放。
以图12C为例，视频播放过程中，目标区域由第一区域切换为第三区域，这个过程 中，用户可以执行两次图15所示的过程。比如，在手机100确定目标区域是第一区域时，执行一次图15所示的流程，得到一个视频文件，播放该视频文件的过程中，第一区域中的内容快速播放。
在播放到某一帧画面时，手机100检测到用户触发控件1205的操作时，手机100基于所述某一帧画面的后续帧图像重新执行图15所示的流程，得到另一个视频文件，手机100播放另一个视频文件的过程中第三区域快速播放；或者，手机100检测到用户触发控件1203的操作时，手机100对基于该视频文件的所有图像中重新执行图15所示的流程，得到另一个视频文件，手机100播放该另一个视频文件时，鱼被快速播放。
应理解，手机100确定出目标对象之后，假设目标对象快速播放，那么手机100播放完目标对象之后，还未播放完其它对象。请继续参见图15所示，手机100从第1帧原图像播放到第3帧原图像后，目标对象1-3已经播放完毕，但是后续的原图像即第4帧图像到第11帧图像还未播放。
作为一种示例，手机100播放完目标对象后，可以停留在最后一帧目标对象图像，等待后续的原图像播放完毕。请参见图16所示，手机100播放完第3帧原图像后，仍然将目标对象3和第4帧原图像融合，后续的第5帧原图像也是和目标对象3融合，即目标对象1-3播放完毕后，将目标对象3和后续的每帧原图像融合，直到后续的每帧原图像播放完毕。当然，在这个过程中，后续的原图像中仍然使用背景覆盖本身包含的目标对象，前面已经介绍过，不再赘述。
作为另一种示例，手机100可以循环播放目标对象，直到后续的原图像播放完毕。请参见图17所示，手机100播放完第3帧原图像后，将目标对象1和第4帧原图像融合，将目标对象2和第5帧原图像融合，将目标对象3和第6帧原图像融合。也就是说，手机100呈现目标对象1-3循环播放的效果，直到播放完后续的原图像。
作为又一种示例，手机100可以在播放完目标对象之后，停止播放后续的原图像。请继续参见图15所示，手机100播放完由第3帧原图像和目标对象3融合得到的新图像之后，停止视频文件的播放。
上述实施例中，手机100提取出目标对象图像之后，原图像是播放的，在实际应用中，手机100也可以不播放原图像。请继续参见图15所示，手机100也可以将目标对象1-3均和第1帧原图像融合，得到融合后的三帧图像，然后播放这三帧图像。即手机100呈现出目标对象在播放，而背景停留在第1帧原图像的效果，即背景处于静止状态，只有目标对象处于播放状态的。当然，手机100也可以将背景填充其它内容。比如，请参见图18所示，手机100显示背景选项，背景选项中包括原背景(即视频本身的背景)、填充色，指定图像。当填充色被选中时，手机100显示颜色选项供用户选择。假设用户选择黑色，那么手机100播放视频时，目标对象之外的对象即背景全部填充黑色，呈现出画面中只有目标对象，背景为黑色的效果。
当然，手机100也可以将背景替换为其它图像(比如不属于该视频的图像)。比如，请参见图19所示，手机100显示背景选项。背景选项中包括原背景(即视频本身的背景)、填充色，指定图像。当指定图像被选中时，手机100显示图像的存储路径。手机100可以根据图像的存储路径指定图像。这样的话，手机100播放视频时，呈现出目标对象在用户指定的图像中播放的效果(目标对象位于上层，指定图像位于下层，即指定图像是目标对象的背景)。
应理解，图19中指定的图像可以是手机100中存储的任一张图像。作为一种示例，请参见图15所示，手机100提取出目标对象1-3之后，可以将目标对象1-3的图像存储下来，那么手机100指定图像时，可以使用存储下来的目标对象1-3。也就是说，手机100对某一个视频使用本申请实施例提供的视频处理方法进行处理时，可以将提取出的目标对象的图像存储，手机100对另一个视频文件使用本申请实施例的视频处理方法进行处理时，若要指定图像，可以指定所述一个视频上提取出的目标对象，这样的话，可以实现，两个视频文件中的内容互换的效果。
在上面的实施例中，介绍手机100的智能播放模式，下面介绍另一实施例，在该实施例中，手机100可以实现智能录制视频。
图20中的(a)示出了手机100的一GUI，该GUI为手机的桌面2001。当手机100检测到用户点击桌面2001上的相机应用的图标2002的操作后，可以启动相机应用，显示如图20中的(b)所示的另一GUI，该GUI中包括图像拍摄预览界面2003。预览界面2003中包括预览图像、拍照选项、视频选项、智能录像选项2004。当智能录像选项2004被选中时，手机100进入智能录像模式。当录制按键2005被触发时，手机100开始录制视频。
为了帮助用户了解智能录制模式的功能和实现方式。手机100进入智能录制模式时，可以显示如图21中的(a)所示的界面，该界面中包括详情控件2101，当详情控件2101被触发时，手机100显示智能录制模式的相关信息，请参见图21中的(b)所示。
手机100进入智能录像模式后，可以确定目标对象的，以及目标对象的播放速度，以便根据目标对象的播放速度确定视频录制方式(后文介绍)。
在一些实施例中，请参见图22中的(a)所示，手机100显示文字信息“请您点击画面中的目标对象”。假设用户点击预览图像2003中的天鹅，手机100可以显示标识信息2201“已选择天鹅”。此时，用户可以在预览界面2003中继续点击其它对象。假设用户继续点击鱼，手机100可以在标识信息2201中添加“鱼”。当手机100点击确定控件2202时，手机100确定天鹅和鱼是目标对象。
在另一些实施例中，请参见图22中的(b)所示，手机100确定选择框中包含的所有对象为目标对象。假设选择框中包括两个对象天鹅和鱼，则手机100显示标识信息2201中包括“天鹅”和“鱼”。当选择框放大时，选择框中包含的对象个数可能增多，那么标识信息2201中包含的对象增多。当手机100检测到触发确定控件2202的操作时，确定标识信息2201中包括的对象是目标对象。
在另一些实施例中，请参见图22中的(c)所示，手机100检测到用户选择编号1的对象时，手机100显示标识信息2201中包括编号1。当手机100继续选择编号2的对象时，手机100在标识信息2201中增加编号2。当手机100检测到用户触发确定控件2202的操作时，确定标识信息2201中包括的对象是目标对象。
手机100确定目标对象之后，还可以确定目标对象的播放速度。
在一些实施例中，请参见图23中的(a)所示，手机100显示速度播放选项，包括：2倍速选项，1.5倍速选项，0.5倍速选项。假设用户触发2倍速选项，当手机100检测到触发拍摄控件2005的操作时，手机100开始录制视频。该视频被播放时，以2倍速播放选择的目标对象，以正常速度播放其它对象。
在另一些实施例，手机100确定出的目标对象有多个时，可以确定每个目标对象的播 放速度。比如，请参见图23中的(b)所示，手机100显示两个目标对象各自的播放速度选项。假设用户选择天鹅的播放速度是2倍速，鱼的播放速度是0.5倍速，当手机100检测到触发拍摄控件2005的操作时，开始录制视频。该视频被播放时，天鹅快速播放，鱼慢速播放。
在另一些实施例中，手机100还可以确定除去目标对象之外的背景的播放速度。比如，请参见图23中的(c)所示，手机100还显示背景(除去天鹅和鱼之外的其它对象)的播放速度选项。假设用户选择背景的播放速度是1.5倍速，手机100检测到触发拍摄控件2005的操作时，开始录制视频。该视频被播放时，背景以1.5倍速播放。
在一些实施例中，手机100在录制视频时，可以根据目标对象的播放速度确定视频的录制方式。比如，手机100可以参考最慢的播放速度来采集图像。如前述内容可知，慢速时，手机100可以以高帧率(比如60fps)采集图像，然后将采集的图像以正常播放速度(比如30fps)播放。因此，为了保证慢速播放情况下，手机100有足够的图像来播放，所以手机可以以慢速播放的播放速率来确定图像采集帧率。因此，若手机100确定目标对象慢速播放，可以以高帧率采集图像。比如，1秒采集30帧图像，播放30帧需1秒。以0.5倍播放的话，还是1秒播放30帧，播放时间翻倍要，就要播放60帧图像。因此，手机100可以以60fps的帧率采集图像，即1秒采集60帧图像，还是1秒播放30帧，需要播放2秒，播放时间延长，呈现慢速播放的效果。因此，手机100在录制视频时，可以参考慢速播放的播放速度，以采集足够的图像。
在上述实施例中，由于手机100每秒采集的图像帧数变多，是为了保证目标对象能够慢速播放，若背景(除去目标对象之外的对象)是正常播放的，那么手机100仍然需要从视频中分割出目标对象图像，然后目标对象图像，然后将目标对象图像以正常速度播放，将背景快速播放。其中，背景快速播放的方式可以参见图15所示。这样的话，目标对象播放的过程中播放的帧数较多，而背景是抽取播放即播放帧数较少，所以视频中目标对象呈现慢速播放的效果。
在一些实施例中，手机100在录制视频时，可以根据目标对象的播放速度确定视频录制方式。比如，手机100可以参考最快的播放速度来采集图像。假设用户选择目标对象的播放速度为2倍速，即用户希望录制视频后，将目标对象以2倍速播放。手机100基于上述表1可确定2倍速播放时，要每隔4帧抽取一帧图像。因此，手机100在录制视频时，以正常采集帧率的4倍帧率来采集图像。假设正常采集帧率为60fps，那么手机100以60*4＝240fps的帧率采集图像。这样的话，手机100可以在播放视频时，每隔4帧抽取一帧图像(为了提取目标对象)时，可以保证抽取出的目标对象图像也能足够使用，即保证抽取出的目标对象图像能够连续播放。
下面介绍手机100录制得到视频文件的过程。
在一些实施例中，手机100检测到用于拍摄的指示后，可以采集多帧原图像，然后手机100可以按照图15所示的流程，对多帧原图像进行处理，得到新视频文件，存储该新视频文件(具体过程，请参见前文描述)。当手机100播放新视频时，即可呈现目标对象快速播放的效果。
可选的，目标对象图像的数量少于原图像的数量，请继续参见图15所示，目标对象图像有3个，而原图像有11帧，手机100将目标对象图像和原图像对应融合，只能得到3帧新图像。一种实现方式为，新视频只包括融合得到的3帧新图像。另一种实现方式为， 手机100将目标对象1和第1帧原图像融合得到第一帧新图像，将目标对象2和第2帧原图像融合，得到第二帧新图像，将目标对象3和第3帧图像融合，得到第三帧新图像，继续将目标对象1和第4帧原图像融合，得到第四帧新图像，将目标对象2和第5帧原图像融合，得到第五帧新图像，依次类推，直到得到11帧新图像。这种方式中，新视频中包括11帧新图像，该新视频中目标对象循环播放。又一种实现方式为，手机100将目标对象1和第1帧原图像融合得到第一帧新图像，将目标对象2和第2帧原图像融合，得到第二帧新图像，将目标对象3和第3帧图像融合，得到第三帧新图像，继续将目标对象3和第4帧原图像、第5帧原图像以及后续的每帧原图像融合。这种方式中，新视频中当目标对象播放完毕之后，最后一帧目标对象停留直到整个视频播放完毕。
在另一些实施例中，手机100检测到用于拍摄的指示后，可以采集多帧原图像，得到一个原始视频文件，然后存储该原始视频文件。当手机100检测到触发播放该原始视频文件的操作时，按照图15所示的方式对该原始视频进行处理。在这个实施例中，手机100存储的是原始视频，只有在播放该原始视频时，才执行图15所示的过程。
应理解，手机100在录制视频之前，用户可以在预览界面中指定目标对象和目标对象的播放速度，若手机100存储原始视频，还存储该原始视频的播放信息(比如，录制该原始视频之前，用户指定的目标对象，以及目标对象的播放速度)。当手机100检测到触发播放该原始视频文件的操作时，按照图15所示的方式对该原始视频进行处理(图15所示的过程中，目标对象是用户在预览界面指定的目标对象，抽帧数可以根据用户指定的播放速度和表1确定)。
当然，在另一些实施例中，手机100可以同时存储原始视频文件和新视频文件(对原始视频处理得到的新视频文件)。请参见图24所示，手机100中存储的新视频文件可以设置有标识信息2401，该标识信息2401用于指示该新视频是对原始视频处理得到的新视频。标识信息2401可以是文字信息也可以是图标等，本申请实施例不限定。在这个实施例中，当原始视频文件播放时，并未呈现目标对象快速播放或者慢速播放的效果(即没有执行图15所示的流程)，当新视频文件播放时，呈现目标对象快速播放或者慢速播放的效果。
通过以上描述可知，本申请实施例提供的视频处理方法，能够实现同一视频中不同区域或对象以不同的播放速度呈现给用户。该方法可以适用于多种领域或场景，比如，本申请实施例提供的视频处理方法可以适用于视频监控领域，即将特定的人(即目标对象)快速播放，将其它对象静止或慢速播放等，以便跟踪特定的人。该方法还可以适用于其它场景，比如视频播放app播放电影的场景，或者微信或者QQ视频通话场景、如微信表情包制作等任何可以录制或播放视频或动图的场景。
本申请的各个实施方式可以任意进行组合，以实现不同的技术效果。
在另一些实施例中，手机100可以可以采用与图14或图15类似的方式对视频进行处理，比如，手机100将一个目标对象
