本发明实施例首先提供一种图像采集结构，该图像采集结构可为相机。图1为相机的电气结构框图。摄影镜头1211由用于形成被摄体像的多个光学镜头构成，为单焦点镜头或变焦镜头。摄影镜头1211在镜头驱动器1221的控制下能够在光轴方向上移动，镜头驱动器1221根据来自镜头驱动控制电路1222的控制信号，控制摄影镜头1211的焦点位置，在变焦镜头的情况下，也可控制焦点距离。镜头驱动控制电路1222按照来自微型计算机1217的控制命令进行镜头驱动器1221的驱动控制。
在摄影镜头1211的光轴上、由摄影镜头1211形成的被摄体像的位置附近配置有摄像元件1212。摄像元件1212用于对被摄体像摄像并取得摄像图像数据。在摄像元件1212上二维且呈矩阵状配置有构成各像素的光电二极管。各光电二极管产生与受光量对应的光电转换电流，该光电转换电流由与各光电二极管连接的电容器进行电荷蓄积。各像素的前表面配置有拜耳排列的RGB滤色器。
摄像元件1212与摄像电路1213连接，该摄像电路1213在摄像元件1212中进行电荷蓄积控制和图像信号读出控制，对该读出的图像信号(模拟图像信号)降低重置噪声后进行波形整形，进而进行增益提高等以成为适当的信号电平。
摄像电路1213与A/D转换器1214连接，该A/D转换器1214对模拟图像信号进行模数转换，向总线1227输出数字图像信号(以下称之为图像数据)。
总线1227是用于传送在相机的内部读出或生成的各种数据的传送路径。在总线1227连接着上述A/D转换器1214，此外还连接着图像处理器1215、JPEG处理器1216、微型计算机1217、SDRAM(Synchronous Dynamic random access memory，同步动态随机存取内存)1218、存储器接口(以下称之为存储器I/F)1219、LCD(Liquid Crystal Display，液晶显示器)驱动器1220。

步骤S140：显示所述第二图像。
本实施例提供一种图像处理方法，可应用于包括采集模组的电子设备中，这里的采集模组可包括图1所示的相机或现有的任意一种摄像机等结构。
在本实施例中所述步骤S110中将响应变焦操作，控制采集膜组件进行 数码变焦。例如，用户通过手指触摸触控屏，向电子设备输入变焦操作，在变焦后用户手指撤离，通常会导致电子设备的抖动，再比如说照相机，用户通过旋转镜头的硬件结构进行变焦，当用户撤离操作之后，也有很大概率出现手持设备的抖动。而抖动可能会导致采集的图像因抖动出现重影等图像模糊现象。
在本实施例中为了提高图像质量，例如，减少图像模糊现象，提升图像清晰度，在进行图像采集时会以较大的第一尺寸进行图像采集，获得第一图像。这里的第一尺寸可为对应于单位像素点的个数。
通常电子设备的抖动，会导致采集模块在其所在的竖直平面内的上下左右移动，这样的话，会使图像中的部分区域出现模糊等不清晰的图像质量问题。
在本实施例中电子设备在后台，会裁剪所述第一图像，获得相对于第一图像更小尺寸的第二图像。例如，所述第一尺寸包括S1个单位像素；所述第二图像可包括S2个单位像素；所述S2小于所述S1；且这S2个单位像素为所述S1个单位像素中的部分像素。通常裁剪掉的S1-S2个像素为不满足清晰条件的部分，这样的话，通过电子设备后台的图像裁剪可以使显示的图像清晰度更高，从而对于用户而言实现了防抖处理，提升了电子设备的智能性，
在具体的实现过程中，所述方法还包括删除所述第一图像及存储所述第二图像，方便后续用户的查阅所述第二图像。
在一些实施例中，所述步骤S130可包括：
根据裁剪策略，裁剪掉所述第一图像的至少部分周边区域，形成所述第二图像。
在本实施例中所述电子设备中预先存储有裁剪策略，或从其他电子设备有接收裁剪策略。研究发现，在电子设备抖动过程中采集的图像，模糊 区域通常位于图像的周边。在本实施例中主要根据裁剪策略，裁剪掉第一图像的周边区域，保留所述第一图像的中间区域，形成所述第二图像。
图3A的左图为所述第一图像，图3A的右图为所述第二图像，第一图像中虚线框对应的部分为所述第二图像的部分。显然裁剪获得第二图像的尺寸小于所述第一图像的尺寸，同时第二图像为所述第一图像的中间区域。
图3B的左图为所述第一图像，图3B的右图为所述第二图像，第一图像中虚线框对应的部分为所述第二图像的部分。显然裁剪获得第二图像的尺寸小于所述第一图像的尺寸，同时第二图像包括了所述第一图像的中间区域及部分周边区域。
在有些实施例中，所述步骤S120可包括：
利用变焦后的所述采集模组，采集N张所述第一尺寸的第一图像；其中，所述N为不小于2的整数；
所述步骤S130可包括：
比对N张所述第一图像，裁剪时保留所述N张所述第一图像中的重叠区域，形成所述第二图像。
在本实施例中所述采集模组会在输出第二图像之前，采集多张所述第一图像；所述第一图像为电子设备抖动过程中不同时刻的采集图像。由于电子设备在抖动的过程中，会使得采集模组采集的景物、人物和/或动物等采集对象发生变化，而首先发生变化的区域肯定是周边区域。只要所述电子设备的抖动幅度不是特别大，则两个第一图像肯定会有部分采集对象是保持不变的，且通常这些采集对象均是显现在第一图像的中间区域的，且通常都是清晰的，即所述重叠区域为所述N张第一图像的中间区域。在本实施例中，为了确定保留下来中间区域的尺寸，在本实施例中通过N张第一图像的比对，选择出N张第一图像的重叠区域作为所述中间区域保留，生成所述第二图像。显然，这样形成的所述第二图像的尺寸显然是小于第 一图像的尺寸。
在一些实施例，所述第二尺寸为变焦后预定输出的图像尺寸；
所述步骤S130可包括：
选择所述第一图像中等于所述第二尺寸的中间区域作为保留区域，裁剪所述第一图像，形成所述第二图像。
数码变焦后都会对应一个图像尺寸，在本实施例中所述第二尺寸直接为所述预定的图像尺寸。在本实施例中在裁剪时，以所述第一图像的中心点为第二图像的中心点保留第二尺寸的图像区域，形成第二图像。如前述提到的由于根据研究模糊更高频次的发生在周边区域，显然这样可以提升第二图像的清晰度，提升图像的图像质量。
在一些实施例中，所述步骤S130还可包括：
获取所述第一图像各个区域的清晰度；
选择清晰度满足预设清晰度条件的区域作为保留区域，形成所述第二图像。
在本实施例中可以首先将第一图像划分为多个区域；再利用各种处理方式获取第一图像中各个区域的清晰度。例如，利用边缘梯度检测、相关性检测以及基于统计和/或变化的评价函数，检测各个区域的清晰度。
接下来选择清晰度大于预设阈值或清晰度较高的多个区域，作为裁剪的保留区域，形成所述第二图像。
当然，本实施例所述的方法，根据统计概率清晰度低的区域大概率出现在第一图像的周边，故在本实施例中也可以是基于图像策略的形成所述第二图像。当然，也存在这种可能，周边区域也有部分清晰的时候，本实施例中所述保留区域可以不局限于中间区域，这样可以获得最大的尺寸的第二图像。
可选地，所述步骤S130可包括：将所述第一图像划分为N个等面积 的区域；再根据所述图像的清晰度，选择连续分布的M个满足预设清晰度条件的区域作为保留区域，形成所述第二图像。所述M小于或等于所述N。例如，所述N等于16，所述M可以等于4。保留下来的M个区域可以为所述N个区域的中间区域和/或周边区域。例如，所述步骤S130可包括：
从N个区域中选择清晰度满足所述预设清晰度条件且连续分布的M个区域作为所述保留区域，形成所述第二图像；其中，所述M为小于N的正整数；所述N为第一图像的区域的总个数。
在一些实施例中，所述步骤S120可包括：在变焦后基于一个采集确定操作之后，采集多张等于所述第一尺寸的第一图像；相当于一个采集指令，设备会自动采集2个或2个以上的第一图像。
所述步骤S130可包括：比对N张所述第一图像的清晰度，选择最清晰的第一图像进行裁剪以获得裁剪后的所述第二图像。
在本实施例中选择最清晰的一张进行裁剪即可，不必裁剪每一张第一图像，未裁剪的不够清晰的图像可以直接丢弃，减少存储数据量。
所述步骤S130可包括：当多张所述第一图像中没有一张图像的有连续分布图像且满足预设清秀度的图像区域等于所述第二尺寸时，裁剪多张所述第一图像，获得满足所述预设清晰度的多个图像区域；拼接多个图像区域，获得满足所述预设清晰度条件的所述第二图像。
当没有一张第一图像可以提供第二尺寸的连续清晰的区域时，在本实施例中可以通过裁剪，从不同给的第一图像中获取比较小的满足清晰度的图像区域，然后拼接形成第二图像，对于用户而言可以减少反复采集的次数。

至此，已经按照其功能描述了移动终端100。下面，为了简要起见，将描述诸如折叠型、直板型、摆动型、滑动型移动终端100等等的各种类型的移动终端100中的滑动型移动终端100作为示例。因此，本发明能够应用于任何类型的移动终端100，并且不限于滑动型移动终端100。
如图5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6描述其中根据本发明的移动终端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6，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。MSC 280被构造为与公共电话交换网络(PSTN)290形成接口。MSC 280还被构造为与可以经由回程线路耦接到基站270的BSC 275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6中所示的系统可以包括多个BSC 2750。
每个BS 270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BS 270。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BS 270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等等)。
分区与频率分配的交叉可以被称为CDMA信道。BS 270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BSC 275和至少一个BS 270。基站也可以被称为“蜂窝站”。或者，特定BS 270的各分区可以被称为多个蜂窝站。
如图6中所示，广播发射器(BT)295将广播信号发送给在系统内操作的移动终端100。如图5中所示的广播接收模块111被设置在移动终端100处以接收由BT295发送的广播信号。在图6中，示出了几个卫星300，例如可以采用全球定位系统(GPS)卫星300。卫星300帮助定位多个移动终端100中的至少一个。
在图6中，描绘了多个卫星300，但是理解的是，可以利用任何数目的卫星获得有用的定位信息。如图5中所示的GPS模块115通常被构造为与卫星300配合以获得想要的定位信息。替代GPS跟踪技术或者在GPS跟踪技术之外，可以使用可以跟踪移动终端100的位置的其它技术。另外，至 少一个GPS卫星300可以选择性地或者额外地处理卫星DMB传输。
作为无线通信系统的一个典型操作，BS 270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。特定基站270接收的每个反向链路信号被在特定BS 270内进行处理。获得的数据被转发给相关的BSC 275。BSC提供通话资源分配和包括BS 270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MSC 280，其提供用于与PSTN 290形成接口的额外的路由服务。类似地，PSTN 290与MSC 280形成接口，MSC与BSC 275形成接口，并且BSC 275相应地控制BS 270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)。

以上所述，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，凡按照本发明原理所作的修改，都应当理解为落入本发明的保护范围。
工业实用性
本发明实施例提供的图像处理技术方案，在完成一次数码变焦之后，会采集面积较大的图像，然后通过图像裁剪得到面积较小且清晰度高的图像，作为最终的采集图像存储和/或输出，这样的话，相对于直接采集所需面积的图像，可能因为边缘区域出现不清晰的现象，导致图像质量差的问题，从而提升了用户最终看到的图像的清晰度，提升了用户体验，具有积极的工业效果，且具有实现简便可在工业上广泛推广的应用前景。
