一种移动终端、图片处理方法及计算机存储介质
相关申请的交叉引用
本申请基于申请号为201610822269.7、申请日为2016年09月13日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本申请涉及图像处理技术领域，尤其涉及一种移动终端、图片处理方法及计算机存储介质。
背景技术
随着移动通讯技术的不断进步及高速发展，手机、平板电脑等许多智能终端都具有拍照功能，例如，用户通过使用智能终端拍摄照片之后，可以通过图像处理软件对拍摄的照片进行修改，以改变照片的对比度、饱和度及颜色等图片属性，从而可以使得拍摄的照片更加美观。其中，移动终端中的图片拼接功能也越来越被广泛应用。图片拼接是将两张或者多张具有部分重叠的图像进行无缝拼接，生成一张具有较宽视角的高分辨率图像；它的基本拍摄原理是搜索两张图片的边缘部分，并将成像效果最为接近的区域加以重合，生成一张具有更大视角的图片。
在现有图片拼接的方法中，用户按下拍照键之后，随着移动终端旋转角度的改变，移动终端实时地检测每两张图片的重合区域，然后实时地将拍摄到的图片进行拼接。
在现有图片拼接的方法中，移动终端实时地将拍摄到的图片进行拼接，也就是说，移动终端需要实时地计算每两张图片的重合区域，这样不仅会增加移动终端的处理功耗；而且当拍摄到的全部图片中存在不清晰的图片时，图片拼 接后的显示效果也会受到影响。
发明内容
有鉴于此，本申请实施例提供了一种移动终端及图片处理方法，不仅能够降低移动终端的处理功耗，而且还可以提高图片拼接后的显示效果。
本申请实施例的技术方案是这样实现的：
本申请实施例提供了一种移动终端，所述移动终端包括：
选择单元，当预先保存的图片中存在至少M张清晰度大于预设阈值的图片时，在预先保存的图片中选择清晰度大于预设阈值的M张图片作为待拼接图片，将M张待拼接图片发送给拼接单元，其中，M为大于等于2的自然数；
拼接单元，当M张待拼接图片均满足预设拼接条件时，将M张待拼接图片拼接为一张全景图片。
上述方案中，所述移动终端还包括：
判断单元，判断预先设置的拼接模式是否为开启状态，当所述拼接模式为开启状态时，向所述选择单元发送一个选择指令；

从预先保存的全部图片中，选取N张划分为一组；
以此类推，直至所述预先保存的全部图片中的剩余图片的数量小于N时，将剩余图片划分为一组，得到M组图片。
上述方案中，所述在每组图片中选择一张图片作为待拼接图片包括：
当每组图片中存在大于一张清晰度大于预设阈值的图片时，从清晰度大于预设阈值的图片中选取一张作为待拼接图片。
上述方案中，所述从清晰度大于预设阈值的图片中选取一张作为待拼接图片包括：
选择清晰度最高的图片作为待拼接图片。
上述方案中，所述所述预设拼接条件为：
各个待拼接图片均与M张待拼接图片中的至少一个待拼接图片存在重合区域。
本申请提供一种计算机存储介质，所述计算机存储介质中存储有计算机可执行指令，所述计算机可执行指令包括：

以此类推，直至所述预先保存的全部图片中的剩余图片的数量小于N时， 将剩余图片划分为一组，得到M组图片。
上述方案中，所述计算机可执行指令还包括：
当每组图片中存在大于一张清晰度大于预设阈值的图片时，从清晰度大于预设阈值的图片中选取一张作为待拼接图片。
上述方案中，所述计算机可执行指令还包括：
选择清晰度最高的图片作为待拼接图片。
由此可见，本申请实施例的技术方案中，当预先保存的图片中存在至少M张清晰度大于预设阈值的图片时，可以先在预先保存的图片中选择清晰度大于预设阈值的M张图片作为待拼接图片，然后当M张待拼接图片均满足预设拼接条件时，将M张待拼接图片拼接为一张全景图片。也就是说，在本申请的提出的技术方案中，移动终端可以在预先保存的图片中选择清晰度大于预设阈值的M张图片进行拼接，而不是像现有技术中，移动终端实时地将拍摄到的全部图片进行拼接。由此可见，和现有技术相比，本申请实施例提出的移动终端及图片处理方法，不仅能够降低移动终端的处理功耗，而且还可以提高图片拼接后的显示效果；并且，实现起来简单方便，便于普及，适用范围更广。

如图1中所示的移动终端100可以被构造为利用经由帧或分组发送数据的诸如有线和无线通信系统以及基于卫星的通信系统来操作。
现在将参考图2描述其中根据本申请的移动终端100能够操作的通信系统。
这样的通信系统可以使用不同的空中接口和/或物理层。例如，由通信系统使用的空中接口包括例如频分多址(FDMA)、时分多址(TDMA)、码分多址(CDMA)和通用移动通信系统(UMTS)(特别地，长期演进(LTE))、全球移动通信系统(GSM)等。作为非限制性示例，下面的描述涉及CDMA通信系统，但是这样的教导同样适用于其它类型的系统。
参考图2，CDMA无线通信系统可以包括多个移动终端100、多个基站(BS)270、基站控制器(BSC)275和移动交换中心(MSC)280。MSC280被构造为与公共电话交换网络(PSTN)290形成接口。MSC280还被构造为与可以经由回程线路耦接到基站270的BSC275形成接口。回程线路可以根据若干己知的接口中的任一种来构造，所述接口包括例如E1/T1、ATM、IP、PPP、帧中继、HDSL、ADSL或xDSL。将理解的是，如图2中所示的系统可以包括多个BSC275。
每个BS270可以服务一个或多个分区(或区域)，由多向天线或指向特定方向的天线覆盖的每个分区放射状地远离BS270。或者，每个分区可以由用于分集接收的两个或更多天线覆盖。每个BS270可以被构造为支持多个频率分配，并且每个频率分配具有特定频谱(例如，1.25MHz，5MHz等)。
分区与频率分配的交叉可以被称为CDMA信道。BS270也可以被称为基站收发器子系统(BTS)或者其它等效术语。在这样的情况下，术语“基站”可 以用于笼统地表示单个BSC275和至少一个BS270。基站也可以被称为“蜂窝站”。或者，特定BS270的各分区可以被称为多个蜂窝站。
作为无线通信系统的一个典型操作，BS270接收来自各种移动终端100的反向链路信号。移动终端100通常参与通话、消息收发和其它类型的通信。特定BS270接收的每个反向链路信号被在特定BS270内进行处理。获得的数据被转发给相关的BSC275。BSC提供通话资源分配和包括BS270之间的软切换过程的协调的移动管理功能。BSC275还将接收到的数据路由到MSC280，其提供用于与PSTN290形成接口的额外的路由服务。类似地，PSTN290与MSC280形成接口，MSC与BSC275形成接口，并且BSC275相应地控制BS270以将正向链路信号发送到移动终端100。
移动终端中无线通信单元110的移动通信模块112基于移动终端内置的接入移动通信网络(如2G/3G/4G等移动通信网络)的必要数据(包括用户识别信息和鉴权信息)接入移动通信网络为移动终端用户的网页浏览、网络多媒体播放等业务传输移动通信数据(包括上行的移动通信数据和下行的移动通信数据)。
无线通信单元110的无线互联网模块113通过运行无线热点的相关协议功能而实现无线热点的功能，无线热点支持多个移动终端(移动终端之外的任意移动终端)接入，通过复用移动通信模块112与移动通信网络之间的移动通信连接为移动终端用户的网页浏览、网络多媒体播放等业务传输移动通信数据(包括上行的移动通信数据和下行的移动通信数据)，由于移动终端实质上是复用移动终端与通信网络之间的移动通信连接传输移动通信数据的，因此移动终端消耗的移动通信数据的流量由通信网络侧的计费实体计入移动终端的通信资费，从而消耗移动终端签约使用的通信资费中包括的移动通信数据的数据流量。
基于上述移动终端100硬件结构以及通信系统，提出本申请方法各个实施例。
图3为本申请实施例一提供的移动终端的组成结构示意图，如图3所示， 本申请实施例一提供的移动终端可以包括：选择单元301和拼接单元302；其中，

在本申请的具体实施例中，选择单元301可以采用多种方法在预先保存的图片中选择清晰度大于预设阈值的M张图片作为待拼接图片。较佳地，选择单元301可以先将预先保存的图片划分为M组，然后可以在每组图片中选择一个待拼接图片。
具体地，在本申请的具体实施例中，当预先保存的图片的数量不少于N时，选择单元301可以将预先保存的图片中的N张图片划分为一组；当预先保存的图片的数量少于N时，选择单元301可以将预先保存的图片中全部剩余的图片划分为一组。当每组图片中存在至少一张清晰度大于预设阈值的图片时，选择单元301可以在每组图片中选择一张图片作为待拼接图片。
较佳地，在本申请的具体实施例中，选择单元301还可以用于当每组图片中清晰度大于预设阈值的图片的数量不止一张时，在每组图片中选择清晰度最高的图片作为待拼接图片。
拼接单元302，用于当M张待拼接图片均满足预设拼接条件时，将M张待拼接图片拼接为一张全景图片。
在本申请的具体实施例中，当M张待拼接图片均满足预设拼接条件时，拼接单元302可以将M张待拼接图片拼接为一张全景图片。其中，所述预设拼接条件可以为：各个待拼接图片均与M张待拼接图片中的至少一个待拼接图片存在重合区域。
由此可见，本申请实施例提出的技术方案，移动终端可以先在预先保存的图片中选择清晰度大于预设阈值的M张图片作为待拼接图片，然后当M张待 拼接图片均满足预设拼接条件时，将M张待拼接图片拼接为一张全景图片，不仅能够降低移动终端的处理功耗，而且还可以提高图片拼接后的显示效果；并且，实现起来简单方便，便于普及，适用范围更广。
图4为本申请实施例二提供的移动终端的组成结构示意图，如图4所示，选择单元301可以包括：划分子单元3011和选择子单元3012；其中，
划分子单元3011，用于将预先保存的图片划分为M组图片，将M组图片发送给选择子单元3012。
在本申请的具体实施例中，划分子单元3011可以将预先保存的图片划分为M组图片。从预先保存的全部图片中，选取N张划分为一组；以此类推，直至所述预先保存的全部图片中的剩余图片的数量小于N时，将剩余图片划分为一组，得到M组图片。
划分单元3011可以具体用于当预先保存的图片的数量不少于N时，将预先保存的图片中的N张图片划分为一组；当预先保存的图片的数量少于N时，划分子单元3011可以将预先保存的图片中全部剩余的图片划分为一组。例如，假设预先保存的图片为10张，当N为3时，M为4。即：将第1～3张图片划分为第一组；将第4～6张图片划分为第二组；将第7～9张图片划分为第三组；将第10张划分为第四组。
所述选择子单元，用于当每组图片中存在大于一张清晰度大于预设阈值的图片时，从清晰度大于预设阈值的图片中选取一张作为待拼接图片。
所述选择子单元，用于选择清晰度最高的图片作为待拼接图片。
选择子单元3012，用于当每组图片中存在至少一张清晰度大于预设阈值的图片时，在每组图片中选择一张图片作为待拼接图片。
在本申请的具体实施例中，当每组图片中存在至少一张清晰度大于预设阈值的图片时，选择子单元3012可以在每组图片中选择一张图片作为待拼接图片。较佳地，当每组图片中清晰度大于预设阈值的图片的数量不止一张时，选择子单元3012可以在每组图片中选择清晰度最高的图片作为待拼接图片。
拼接单元302，用于当M张待拼接图片均满足预设拼接条件时，将M张待拼接图片拼接为一张全景图片。
在本申请的具体实施例中，当M张待拼接图片均满足预设拼接条件时，拼接单元302可以将M张待拼接图片拼接为一张全景图片。其中，所述预设拼接条件可以为：各个待拼接图片均与M张待拼接图片中的至少一个待拼接图片存在重合区域。
较佳地，在本申请的具体实施例中，所述移动终端还可以包括：
判断单元303，用于判断预先设置的拼接模式是否为开启状态；当拼接模式为开启状态时，向选择单元301发送一个选择指令；
选择单元301，用于在接收到选择指令之后，在预先保存的图片中选择清晰度大于预设阈值的M张图片作为待拼接图片。
在本申请的具体实施例中，可以在移动终端中预先设置拼接模式；当拼接模式为开启状态时，移动终端才可以将待拼接图片拼接为一张全景图片；当拼接模式为关闭状态时，移动终端则不能将待拼接图片拼接为一张全景图片。较佳地，在本申请的具体实施例中，判断单元303可以先判断预先设置的拼接模式是否为开启状态，当拼接模式为开启状态时，判断单元303向选择单元301发送一个选择指令；选择单元301，用于在接收到选择指令之后，在预先保存的图片中选择清晰度大于预设阈值的M张图片作为待拼接图片。
本申请实施例提供的选择单元301和拼接单元302都可以通过移动终端中的处理器来实现；当然也可通过具体的逻辑电路实现；在具体实施例的过程中，处理器可以为中央处理器(CPU)、微处理器(MPU)、数字信号处理器(DSP)或现场可编程门阵列(FPGA)等。
本申请实施例提出的移动终端，可以在预先保存的图片中选择清晰度大于预设阈值的M张图片进行拼接，而不是像现有技术中，移动终端实时地将拍摄到的全部图片进行拼接。由此可见，和现有技术相比，本申请实施例提出的移动终端及图片处理方法，不仅能够降低移动终端的处理功耗，而且还可以提高 图片拼接后的显示效果；并且，实现起来简单方便，便于普及，适用范围更广。
图5为本申请实施例中图片处理方法的实现流程示意图，如图5所示，图片处理方法可以包括以下步骤：
步骤501、当预先保存的图片中存在至少M张清晰度大于预设阈值的图片时，在预先保存的图片中选择清晰度大于预设阈值的M张图片作为待拼接图片。
在本申请的具体实施例中，移动终端可以采用多种方法当预先保存的图片中选择清晰度大于预设阈值的M张图片作为待拼接图片，其中，M为大于等于2的自然数。较佳地，在本申请的具体实施例中，移动终端可以先将预先保存的图片划分为M组，然后可以在每组图片中选择一个待拼接图片。
具体地，在本申请的具体实施例中，当预先保存的图片的数量不少于N时，移动终端可以将预先保存的图片中的N张图片划分为一组；当预先保存的图片的数量少于N时，移动终端可以将预先保存的图片中全部剩余的图片划分为一组。当每组图片中存在至少一张清晰度大于预设阈值的图片时，移动终端可以在每组图片中选择一张图片作为待拼接图片。
较佳地，在本申请的具体实施例中，移动终端还可以用于当每组图片中清晰度大于预设阈值的图片的数量不止一张时，在每组图片中选择清晰度最高的图片作为待拼接图片。
图6为本申请实施例中选择待拼接图片的实现方法流程示意图，如图6所示，在预先保存的图片中选择待拼接图片的方法可以包括以下步骤：
步骤501a、将预先保存的图片划分为M组图片。
在本申请的具体实施例中，移动终端可以先将预先保存的图片划分为M组，然后可以在每组图片中选择一个待拼接图片。具体地，从预先保存的全部图片中，选取N张划分为一组；以此类推，直至所述预先保存的全部图片中的剩余图片的数量小于N时，将剩余图片划分为一组，得到M组图片。
移动终端可以将预先保存的图片中的N张图片划分为一组，以此类推，每 次划分完成一组之后，就从预先保存的图片中删除已经划分的图片；当预先保存中的剩余图片的数量少于N时，移动终端可以将预先保存的图片中全部剩余的图片划分为一组。例如，假设预先保存的图片为10张，当N为3时，M为4。即：将第1～3张图片划分为第一组；将第4～6张图片划分为第二组；将第7～9张图片划分为第三组；将第10张划分为第四组。
步骤501b、当每组图片中存在至少一张清晰度大于预设阈值的图片时，在每组图片中选择一张图片作为待拼接图片。
在本申请的具体实施例中，当每组图片中存在大于一张清晰度大于预设阈值的图片时，从清晰度大于预设阈值的图片中选取一张作为待拼接图片。其中，选取可以为任意选择一张作为待拼接图片；当然还可以选取清晰度最大的一张作为待拼接图片。
具体的，当每组图片中存在至少一张清晰度大于预设阈值的图片时，移动终端可以在每组图片中选择一张图片作为待拼接图片。较佳地，当每组图片中存在不止一张清晰度大于预设阈值的图片时，移动终端可以选择清晰度最高的图片作为待拼接图片。
步骤502、当M张待拼接图片均满足预设拼接条件时，将M张待拼接图片拼接为一张全景图片。
在本申请的具体实施例中，当M张待拼接图片均满足预设拼接条件时，移动终端可以将M张待拼接图片拼接为一张全景图片。其中，所述预设拼接条件可以为：各个待拼接图片均与M张待拼接图片中的至少一个待拼接图片存在重合区域。
较佳地，在本申请的具体实施例中，可以在移动终端中预先设置拼接模式；当拼接模式为开启状态时，移动终端才可以将待拼接图片拼接为一张全景图片；当拼接模式为关闭状态时，移动终端则不能将待拼接图片拼接为一张全景图片。因此，移动终端可以先判断预先设置的拼接模式是否为开启状态，当拼接模式为开启状态时，移动终端可以在预先保存的图片中选择清晰度大于预设阈值的 M张图片作为待拼接图片。
本申请实施例提出的图片处理方法，移动终端可以在预先保存的图片中选择清晰度大于预设阈值的M张图片进行拼接，而不是像现有技术中，移动终端实时地将拍摄到的全部图片进行拼接。由此可见，和现有技术相比，本申请实施例提出的移动终端及图片处理方法，不仅能够降低移动终端的处理功耗，而且还可以提高图片拼接后的显示效果；并且，实现起来简单方便，便于普及，适用范围更广。
