至此，已经按照其功能描述了移动终端。下面，为了简要起见，将描述诸如折叠型、直板型、摆动型、滑动型移动终端等等的各种类型的移动终端中的滑动型移动终端作为示例。因此，本发明能够应用于任何类型的移动终端，并且不限于滑动型移动终端。
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描述其中根据本发明的移动终端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。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BS 270的BSC 275形成接口。回程线路可以根据若干已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BSC 275。
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2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1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2中，示出了几个全球定位系统(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2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。作为图1中所示的位置信息模块115的GPS模块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BS 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。BSC 275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 280与BSC 275形成接口，并且BSC275相应地控制BS 270以将正向链路信号发送到移动终端100。
基于上述移动终端硬件结构以及通信系统，提出本发明方法各个实施例。

S101、终端采集拍照区域中待处理的第一图像。
需要说明的是，本发明实施例的应用场景可以是在终端进行摄像或照相的过程中，终端在拍照区域(例如，镜头的成像区域)采集到的待拍摄的图像，即未处理过的第一图像，配置为作为摄像或照相的预览，对这个第一图像进行风格化处理。
在本发明实施例中，终端可以为手机、平板电脑等具有摄像或照相功能的电子设备。
需要说明的是，本发明实施例中实现摄像或照相的即时性风格化功能，可以通过设置好的风格化按钮来实现。以终端为手机为例进行说明，用户在使用手机进行照相时，该手机启动照相功能后，可以启动在手机显示器上设置好的风格化按钮，这样拍出的照片就可以是处理好的风格化图像。
优选地，在本发明实施例中，风格化按钮的设置位置即形状、大小等 基本信息，本发明实施例并不作限制，可以根据实际的需要和喜好进行设计。
例如，终端采集拍照区域中待处理的第一图像，该第一图像可以为终端通过摄像头获取的图像或画面。
需要说明的是，在本发明实施例中的第一图像为彩色图像，本发明实施例的目的是对第一图像进行彩色风格化图像的处理。
可以理解的是，在终端的拍摄的过程中，通过对原始的第一图像做风格化处理，使得终端显现的拍摄风格多样化，于是，提升了用户的体验感。
优选地，终端采集的第一图像中会存在拍照区域中特定的对象如比较重要的物体，即第一图像的主体，或者说是第一图像中想要表达的物体。
可选的，第一图像的主体可以为：人物、建筑、大海、动物等等，本发明实施例并不作限制，而是根据实际拍摄情况来决定的。
S102、终端对第一图像进行边缘化处理，生成彩色边缘轮廓图像。
终端采集拍照区域中待处理的第一图像之后，该终端并不是将拍摄到的第一图像直接显示使用，而是会对该第一图像进行一些处理，达到用户想要的效果，即该终端对该第一图像进行边缘化处理，将第一图像的主体边缘突出，生成或者得到彩色边缘轮廓图像。
需要说明的是，现有的对第一图像的边缘化处理的方法都可以应用到本发明实施例中来，其中，对第一图像的边缘化处理的主要目的是为了将第一图像中的主体的边缘轮廓更好地体现出来。
其中，本发明实施例中可以通过下面的方法对第一图像进行边缘化处理：
(1)、终端对第一图像进行对比度处理，生成第二图像。
(2)、终端将第二图像进行平滑处理，得到第三图像。
(3)、终端对第二图像和第三图像进行色彩差值运算，得到彩色边缘 轮廓图像。
优选地，(1)、(2)和(3)的实现过程和事例将在后续的实施例中进行详细地说明。
S103、终端对彩色边缘轮廓图像进行边缘和色彩的深化，生成滤镜图像。
终端对第一图像进行边缘化处理，生成彩色边缘轮廓图像之后，终端就已经处理得到第一图像的彩色边缘轮廓，然后在检测彩色边缘轮廓(例如，使用边缘检测算法)的同时，保留第一图像中的色彩的差异性，即对彩色边缘轮廓图像进行边缘和色彩的深化，最后得到滤镜图像。
例如，终端可以根据第二图像和第三图像，对彩色边缘轮廓图像进行边缘和色彩的深化，生成滤镜图像。
需要说明的是，滤镜图像与第一图像相比，第一图像的主体的彩色边缘轮廓更明显，且保留了留第一图像中主体的色彩的差异性，因此，可以轻易检测到第一图像中的主体的影像。
S104、终端将第一图像和滤镜图像进行图像混合，生成风格化图像。
终端对彩色边缘轮廓图像进行边缘和色彩的深化，生成滤镜图像之后，该终端可以将第一图像和滤镜图像进行图像混合，生成风格化图像。
需要说明的是，终端生成了滤镜图像，将第一图像与滤镜图像混合，就可以得到想要的风格化第一图像后的图像了。
可以理解的是，本发明实施例中的滤镜图像的生成是风格化模型的形成过程，想要将第一图像风格化，就要将第一图像和风格化模型进行混合来实现。
优选地，在本发明实施例中，对所有图像的处理都是基于R、G、B三基色的通道上进行的处理，将在后续实施例中进行详细的说明。
本发明实施例所提供的一种图像处理方法，通过采集拍照区域中待处 理的第一图像；对第一图像进行边缘化处理，生成彩色边缘轮廓图像；对彩色边缘轮廓图像进行边缘和色彩的深化，生成滤镜图像；将第一图像和滤镜图像进行图像混合，生成风格化图像，采用上述技术实现方案，由于终端在进行实时摄像或照相时，可以对拍照区域的未处理的第一图像进行彩色风格化的处理，实现了终端实时自动生成风格化图像的过程，且采用彩色边缘轮廓提取和色彩差异化保持，因此，提高了图像的风格化的效果。
实施例二
本发明实施例提供一种图像处理方法，如图4所示，该方法可以包括：
S201、终端采集拍照区域中待处理的第一图像。
需要说明的是，本发明实施例的应用场景可以是在终端进行摄像或照相的过程中，终端在拍照区域(例如，镜头的成像区域)采集到的待拍摄的图像，即未处理过的、预览到的第一图像，对这个第一图像进行风格化处理。
在本发明实施例中，终端可以为手机、平板电脑等具有摄像或照相功能的电子设备。
需要说明的是，本发明实施例中实现摄像或照相的即时性风格化功能，可以通过设置好的风格化按钮来实现。以终端为手机为例进行说明，用户在使用手机进行照相时，该手机启动照相功能后，可以启动在手机显示器上设置好的风格化按钮，这样拍出的照片就可以是处理好的风格化图像。
优选地，在本发明实施例中，风格化按钮的设置位置即形状、大小等基本信息，本发明实施例并不作限制，可以根据实际的需要和喜好进行设计。
例如，终端采集拍照区域中待处理的第一图像，该第一图像可以为终端通过摄像头获取的图像或画面。
需要说明的是，在本发明实施例中的第一图像为彩色图像，本发明实 施例的目的是对第一图像进行彩色风格化图像的处理。
可以理解的是，在终端的拍摄的过程中，通过对原始的第一图像做风格化处理，使得终端显现的拍摄风格多样化，于是，提升了用户的体验感。
优选地，终端采集的第一图像中会存在这个图像中比较重要的物体，即第一图像的主体，或者说是第一图像中想要表达的物体。
可选的，第一图像的主体可以为：人物、建筑、大海、动物等等，本发明实施例并不作限制，而是根据实际拍摄情况来决定的。
S202、终端对第一图像进行对比度处理，生成第二图像。
终端采集拍照区域中待处理的第一图像之后，该终端并不是将拍摄到的第一图像直接显示使用，而是会对该第一图像进行一些处理，达到用户想要的效果，即该终端对该第一图像进行边缘化处理，将第一图像的主体边缘突出，生成或者得到彩色边缘轮廓图像。
需要说明的是，现有的对第一图像的边缘化处理的方法都可以应用到本发明实施例中来，其中，对第一图像的边缘化处理的主要目的是为了将第一图像中的主体的边缘轮廓更好地体现出来。
在本发明实施例中，首先终端对第一图像进行对比度处理，生成第二图像。
例如，终端降低(例如，按照既定幅度降低)第一图像中最亮区域和最暗区域的边缘对比度，提高该第一图像中主体的边缘对比度，并对主体的边缘强度进行放大(例如，按照既定倍数放大)，从而生成第二图像。
需要说明的是，终端将第一图像中的颜色相近线条的色调统一，这样就将主体的彩色边缘的对比度体现了出来。
在本发明实施例中，对所有图像的处理都是基于R、G、B三基色的通道上分别进行的处理，对第一图像进行对比度处理时，将第一图像分解为三基色的分量图像，对三基色的分量图像的对比度进行处理，合并处理后 三基色分量图像得到第二图像。
例如，终端对第一图像进行对比度调整，得到第二图像本发明中对比度的调整采用公式(1)：
Figure PCTCN2016101934-appb-000001
其中，I1为第一图像中像素点对应的R、G、B任意颜色通道的像素值；I2为第二图像中像素点对应R、G、B任意颜色通道的像素值；TL为第一图像的像素最低阈值；TH为第一图像的像素最高阈值；k为变换系数；TL、TH以及k的值可根据时间需要进行设置，本发明实施例不作限制。
可选的，k＝2.0，TL＝64，TH＝192。
可选的，R、G、B像素值的取值范围为0-255。
S203、终端将第二图像进行平滑处理，得到第三图像。
终端对第一图像进行对比度处理，生成第二图像之后，该终端将第二图像进行平滑处理，得到第三图像。
需要说明的是，这个步骤主要是对提高对比度后的第二图像进行平滑降噪的作用，去除掉杂乱的彩色边缘。
例如，终端可以对第二图像进行高斯滤波，得到第三图像，可以通过现有的高斯滤波的技术对本发明实施例进行处理，故在此不再敖述。
S204、终端对第二图像和第三图像进行色彩差值运算，得到彩色边缘轮廓图像。
终端将第二图像进行平滑处理，得到第三图像之后，该终端可以对第二图像和第三图像进行色彩插值运算，获取彩色边缘轮廓信息，得到彩色边缘轮廓图像。
例如，第二图像与第三图像进行差值运算，获取得到轮廓的彩色边缘 轮廓图像，可以根据如下公式(2)进行处理：
I4＝abs(I2-I3)         (2)
其中，I4为彩色边缘轮廓图像的R、G、B像素值；将I3表示为第三图像的R、G、B像素值。
S205、终端根据第二图像和第三图像，对彩色边缘轮廓图像进行边缘和色彩的深化，生成滤镜图像。
终端得到彩色边缘轮廓图像之后，该终端可以根据第二图像和第三图像，对彩色边缘轮廓图像进行边缘和色彩的深化，生成滤镜图像。
例如，根据如下公式(3)对彩色边缘轮廓图像进行调整计算边缘，得到滤镜图像：
I5＝255*I2/(I3+I4)          (3)
其中，I5为滤镜图像的R、G、B像素值。
需要说明的是，终端对第一图像进行边缘化处理，生成彩色边缘轮廓图像之后，终端就已经将第一图像的彩色边缘轮廓处理得到了，然后在获取彩色边缘轮廓的同时，保留第一图像中的色彩的差异性，即对彩色边缘轮廓图像进行边缘和色彩的深化，最后得到滤镜图像。其中，滤镜图像与第一图像相比，第一图像的主体的彩色边缘轮廓更明显，且保留了留第一图像中主体的色彩的差异性，因此，可以明显地看出第一图像中的主体的影像了。
S206、终端将第一图像和滤镜图像进行图像混合，生成风格化图像。
终端生成滤镜图像之后，该终端可以将第一图像和滤镜图像进行图像混合，生成风格化图像。
需要说明的是，终端生成了滤镜图像，将第一图像与滤镜图像混合，就可以得到想要的风格化第一图像后的图像了。
例如，本发明中，滤镜图像与第一图像进行混合可以根据如下的公式 (4)：
I6＝255-I1*I5/255          (4)
其中，I6为风格化图像的R、G、B像素值。
可以理解的是，本发明实施例中的滤镜图像的生成是风格化模型的形成过程，想要将第一图像风格化，就要将第一图像和风格化模型进行混合来实现。
S207、终端在显示区域显示所述风格化图像。
终端生成风格化图像之后，该终端会在显示区域内显示处理好的风格化图像。
可以理解的是，终端在风格化模式下，进行拍摄时，直接显示的是处理好的风格化图像，因此，终端可以实时地进行风格化图像的获取。
下面通过一个例子来说明本发明实施例提供的图像处理方法。
假设使用手机进行拍照，在该手机的预览区域(显示屏)看到的是一栋建筑的风景画，如图5所示，图5为本发明实施例中的第一图像，经过对比度处理后，生成图6所示的第二图像，该手机将第二图像进行平滑处理，得到如图7所示的第三图像，以及该手机对第二图像和第三图像进行色彩差值运算，得到如图8所示的彩色边缘轮廓图像，然后，手机根据第二图像和第三图像，对彩色边缘轮廓图像进行边缘和色彩的深化，生成如图9所示的滤镜图像，最后，手机将第一图像和滤镜图像进行图像混合，生成如图10所示风格化图像，并将该风格化图像在显示屏上显示出来。
需要说明的是，根据专利撰写的附图要求，本发明实施例中的图5、图6、图7、图8、图9和图10都是去色之后的图片。但是，采用本发明实施例提供的图像处理方法是对彩色图像的处理，处理的结果也是彩色的。
本发明实施例所提供的一种图像处理方法，通过采集拍照区域中待处理的第一图像；对第一图像进行边缘化处理，生成彩色边缘轮廓图像；对 彩色边缘轮廓图像进行边缘和色彩的深化，生成滤镜图像；将第一图像和滤镜图像进行图像混合，生成风格化图像，采用上述技术实现方案，由于终端在进行实时摄像或照相时，可以对拍照区域的未处理的第一图像进行彩色风格化的处理，实现了终端实时自动生成风格化图像的过程，且采用彩色边缘轮廓提取和色彩差异化保持，因此，提高了图像的风格化的效果。
