Description
本发明涉及通信领域，具体而言，涉及一种摄像处理方法及装置。
随着智能设备(例如，智能手机)性能的提升，很多单反相机上的功能都可以在智能设备上实现了，因此，对于智能设备上Camera功能的需求，就越来越专业化。目前，在各种高端的终端项目都实现了慢动作高速摄像功能，通过高速摄像能够帮助人眼来感受时间的快慢。这是个很有趣味的应用，可以将各种场景，定格在比较短的瞬间。对于目前实现的方案，在高速摄像中，摄像帧率在一个几乎固定的范围内，使得摄像速度也是固定的，而摄像帧率一般是比较高的，如，摄像帧率为360fps时，也就是一秒钟会有360帧数据，如果播放的时候，视屏播放器按照播放帧率为30fps来播，这样视屏播放器就需要12秒钟播放完高速摄像一秒钟的内容，因为播放时每一帧之间差异变得更小，即每一帧之间的时间差变长，对于眼睛的直观感觉上，会达到一种画面放慢的效果。但是，视屏播放器在播放高速摄像的内容时，会存在一个问题，播放过程中每一帧之间的时间差是相同的，用户感受到的慢的感觉是固化的。
因此，相关技术中无法动态的调节高速摄像的摄像速度，导致视频播放器在播放高速摄像内容过程中每一帧之间的时间差相同的问题，使得用户感受到的慢的感觉是固化的，无法感觉到画面的速度感。

实施例1
本申请实施例1所提供的方法实施例可以在移动终端、计算机终端或者类似的运算装置中执行。以运行在移动终端上为例，图1是本发明实施例的一种摄像处理方法的移动终端的硬件结构框图。如图1所示，移动终端10可以包括一个或多个(图中仅示出一个)处理器102(处理器102可以包括但不限于微处理器MCU或可编程逻辑器件FPGA等的处理装置)、用于存储数据的存储器104、以及用于通信功能的传输装置106。本领域普通技术人员可以理解，图1所示的结构仅为示意，其并不对上述电子装置的结构造成限定。例如，移动终端10还可包括比图1中所示更多或者更少的组件，或者具有与图1所示不同的配置。
存储器104可用于存储应用软件的软件程序以及模块，如本发明实施例
中的摄像处理方法对应的程序指令/模块，处理器102通过运行存储在存储器104内的软件程序以及模块，从而执行各种功能应用以及数据处理，即实现上述的方法。存储器104可包括高速随机存储器，还可包括非易失性存储器，如一个或者多个磁性存储装置、闪存、或者其他非易失性固态存储器。在一些实例中，存储器104可进一步包括相对于处理器102远程设置的存储器，这些远程存储器可以通过网络连接至移动终端10。上述网络的实例包括但不限于互联网、企业内部网、局域网、移动通信网及其组合。
传输装置106用于经由一个网络接收或者发送数据。上述的网络具体实例可包括移动终端10的通信供应商提供的无线网络。在一个实例中，传输装置106包括一个网络适配器(Network Interface Controller，NIC)，其可通过基站与其他网络设备相连从而可与互联网进行通讯。在一个实例中，传输装置106可以为射频(Radio Frequency，RF)模块，其用于通过无线方式与互联网进行通讯。
在本实施例中提供了一种运行于上述移动终端的摄像处理方法，图2是根据本发明实施例的摄像处理方法的流程图，如图2所示，该流程包括如下步骤：
步骤S202，获取预定音频源在预定时刻的音频对应的音频速度；
步骤S204，根据获取的音频速度，以及音频速度与摄像帧率的对应关系，确定获取的音频速度对应的摄像帧率；
步骤S206，根据确定的摄像帧率调整摄像速度。
通过上述步骤，将高速摄像的摄像帧率与音频结合在一起，根据获取的音频源的的音频对应的音频速度，确定高速摄像的摄像帧率，因为音频的音频速度总是动态变化的，所以根据音频的音频速度确定的摄像帧率也是动态变化的，进而实现了动态的调节摄像速度，因此，可以解决相关技术中无法动态调节高速摄像的摄像速度的问题，使得用户可以感觉到画面
的速度感。
在本发明实施例一实施方式中，获取预定音频源在预定时刻的音频速度包括：获取预定音频源在预定时刻的音频对应的音频信息至少之一：响度加速度，音调加速度，音色加速度；根据获取的音频信息至少之一，确定音频速度。通过上述步骤，通过音频的响度、音调、音色中之一确定音频速度，或者通过三者的结合确定音频速度，又或者通过两者的结合确定音频速度，使得用户可以根据喜好，方便的获取所需的音频速度。
在本发明实施例一实施方式中，在获取预定音频源在预定时刻的音频对应的音频速度之前，还包括：对预定时刻的音频进行加权滤波。通过上述步骤，滤除预定音频源中用户不可听的频率，将预定音频源的频率限定在用户可听的范围内容，提高了用户的体验度。
在本发明实施例一实施方式中，在根据获取的音频速度，以及音频速度与摄像帧率的对应关系，确定获取的音频速度对应的摄像帧率之前，还包括：根据最大摄像帧率，预先选择的视频播放器的固定播放帧率，以及预定时刻的音频信息至少之一，确定音频速度与摄像帧率的对应关系，其中，最大摄像帧率由摄像设备的硬件决定。通过上述步骤，根据选定的视频播放器的固定播放帧率确定音频速度与摄像帧率的对应关系，使得通告确定的摄像帧率获取的摄像内容可以流利的在选定的视频播放器上播放。
例如，关于判断声音速度的模型，我们建立一种帧率与声音三因素相关的公式，用来将声音与帧率做一个匹配。
Current FR＝Play FR–(WFacotr_Volume*AV+WFacotr_Freq*BV+WFacotr_Tone*CV)*t；其中，t对应的是时间。
Current FR:变量，在高速摄像过程中，根据音频速度确定的、下发到Camera sensor的摄像帧率,控制图像传感器输出图像的速度；
Play FR：常量，视频播放器固定的播放帧率，例如，可以设置为{30-720}中的某个值。所通过有音频分析模块得出的帧率，取值都在{30-Play FR}，
{Play FR-720}这个范围内，上述720帧只是假设的摄像设备的最大帧率的一个值，随着技术发展，也会出现更高帧率，本专利不限制它，720仅仅作为一个例子。
WFacotr_Volume、WFacotr_Freq、WFacotr_Tone：分别对应响度、音调、音色判断声音速度的权重,可以动态调节，取值范围{0-100％}，WFacotr_Volume+WFacotr_Freq+WFacotr_Tone＝100％
AV、BV、CV：响度、音调以及音色，三者变化的加速度；对于AV，表示在单位时间内，声音从一个量度DB值变化到另外一个DB值，而BV则是表示在单位频率变化的幅度，CV则表示在单位时间内，声音的谐波成分的变化情况。三因素的加速度对应的单位为：帧率/每单位变化率，即声音的强度、频率、和谐波范围的变化率。
在本发明实施例一实施方式中，上述音频源包括以下至少之一：本地存储的音频文件，实时录制的音频文件。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到根据上述实施例的方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本发明的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端设备(可以是手机，计算机，服务器，或者网络设备等)执行本发明各个实施例所述的方法。
