技术领域
本发明涉及电子设备技术领域，特别是涉及一种电子设备实现哈哈镜拍照效果的方法和装置。
背景技术
哈哈镜由于具有趣味性而受到很多人的欢迎，但是哈哈镜特有的效果并不能很方便的保存成电子照片来进行纪念或分享。
现在智能手机的拍照技术很成熟，但是目前还没有成熟的方案将哈哈镜效果添加进手机的相机应用。如果用户想给照片添加哈哈镜效果，则只能利用PhotoShop(一种图像处理软件)等后期处理软件进行处理，效率很低，并且照片质量会有一定程度的损失，用户体验差。
发明内容
本发明实施例提供一种电子设备实现哈哈镜拍照效果的方法和装置，用以在一定程度上解决目前没有成熟的方案将哈哈镜效果添加进手机的相机应用，以及后期处理软件进行哈哈镜效果处理时，效率很低，并且照片质量会有一定程度的损失，用户体验差的问题。
为了解决上述问题，本发明实施例公开了一种电子设备实现哈哈镜拍照效果的方法，包括以下步骤：运行电子设备的拍摄模式；获取电子设备的摄像头模组实时取景的每一帧图像数据，并根据预设哈哈镜算法实时对所述每一帧图像数据进行处理，将处理后的图像数据显示在电子设备的拍摄预览界面；接收拍照指令；获取摄像头模组采集的图像数据，并根据所述预设哈哈镜算法对所述采集的图像数据进行处理，根据处理后的图像数据生成压缩编 码图片。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于 本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明实施例的电子设备可以为手机、相机、笔记本电脑或平板电脑等具有拍照功能的电子设备。
参照图1，示出了本发明的一种电子设备实现哈哈镜拍照效果的方法实施例的步骤流程图。该电子设备实现哈哈镜拍照效果的方法可以包括以下步骤：
S1，运行电子设备的拍摄模式。
其中，当用户打开电子设备的相机功能后，步骤S1运行电子设备的拍摄模式。
S2，获取电子设备的摄像头模组实时取景的每一帧图像数据，并根据预设哈哈镜算法实时对每一帧图像数据进行处理，将处理后的图像数据显示在电子设备的拍摄预览界面。
其中，摄像头模组可以包括摄像头、模数转换模块等。具体地，步骤S1后，电子设备的摄像头模组实时取景即摄像头模组接收光信息，并对接收的光信息进行模数转换等前期处理以获得上述的每一帧图像数据。
通过步骤S2，可以实现在摄像头模组取景时，通过电子设备的软件系统对取景的每一帧图像数据，直接先根据预设哈哈镜算法进行处理之后，再送给电子设备的显示屏显示，从而可以最大程度保证拍摄预览界面例如相机APP(Application，应用程序)的拍摄预览界面中图片像素不损失，且使得用户在拍摄预览界面，就可以实时直观的看到照片的哈哈镜效果，极大地提高了用户体验。
S3，接收拍照指令。
具体地，当用户根据拍摄预览界面确定所需哈哈镜效果为当前哈哈镜效果后，若用户点击拍摄按钮，步骤S3接收拍照指令。
S4，获取摄像头模组采集的图像数据，并根据预设哈哈镜算法对采集的图像数据进行处理，根据处理后的图像数据生成压缩编码图片。
步骤S3后，摄像头模组采集光信息，并对采集的光信息进行模数转换等前期处理后以获得上述采集的图像数据。
其中，在本发明的一个实施例中，当摄像头模组采集到图像数据后，可以缓存该采集的图像数据至系统内存，以便于步骤S4可以高效的根据预设哈哈镜算法对采集的图像数据进行处理。
其中，步骤S4可以通过电子设备的软件系统，直接根据预设哈哈镜算法对摄像头模组采集且未压缩编码的图像数据进行处理，进而通过电子设备的软件系统，再对处理后的图像数据进行压缩编码为预设格式的图片，该图片为具有用户所需哈哈镜效果的图片。从而可以最大程度保证成片像素不损失，极大地提高了用户体验。具体地，预设格式可以为JPEG(Joint Photographic Experts Group，联合图像专家小组)格式、GIF(Graphics Interchange Format，图像互换格式)格式或PNG((Portable Network Graphic Format，可移植网络图形格式)格式等格式。
其中，当缓存该采集的图像数据至系统内存后，在步骤S4根据处理后的图像数据生成压缩编码图片后，还可以释放该采集的图像数据所占用的系统内存，从而可以提高系统效率。
具体地，在本发明的一个实施例中，上述预设哈哈镜算法可以包括：对第一指定图像区域内的图像数据按第一预设比例进行压缩。
其中，对第一指定图像区域内的图像数据按第一预设比例进行压缩可以为对第一指定图像区域内的图像数据中像素数目按第一预设比例进行压缩，第一预设比例大于0且小于1。
具体地，当用户打开相机功能后，拍摄预览界面可以显示压缩方向选择列表，压缩方向选择列表可以包括横向压缩按钮、纵向压缩按钮和圆形压缩按钮等，以及拍摄预览界面可以显示压缩比例调整按钮或压缩比例选择列表等。
其中，当用户选择横向压缩按钮时，拍摄预览界面显示两条纵向的调整线，该两条纵向的调整线之间的区域即为第一指定图像区域，用户移动任一条调整线，即可调整第一指定图像区域的大小；当用户选择纵向压缩按钮时，拍摄预览界面显示两条横向的调整线，该两条横向的调整线之间的区域即为第一指定图像区域，用户移动任一条调整线，即可调整第一指定图像区域的大小；当用户选择圆形压缩按钮时，拍摄预览界面显示圆形的调整线，该圆形的调整线之间的区域即为第一指定图像区域，用户调整圆形的半径，即可 调整第一指定图像区域的大小。另外，用户可以通过压缩比例调整按钮或通过压缩比例选择列表等，对第一预设比例进行调整。
在本发明的一个具体实施例中，当用户选择横向压缩按钮，并设置第一预设比例为50％，第一指定图像区域内的图像数据如图2所示，则在根据预设哈哈镜算法进行压缩处理后的第一指定图像区域内的图像数据如图3所示，其中，图2中的两条纵向的调整线如图中虚线所示。
具体地，在本发明的一个实施例中，上述预设哈哈镜算法可以包括：对第二指定图像区域内的图像数据按第二预设比例进行扩充。第二预设比例大于1。
其中，对第二指定图像区域内的图像数据按第二预设比例进行扩充可以为对第二指定图像区域内的图像数据中像素数目按第二预设比例进行扩充。
具体地，当用户打开相机功能后，拍摄预览界面可以显示扩充方向选择列表，扩充方向选择列表可以包括横向扩充按钮、纵向扩充按钮和圆形扩充按钮等，以及拍摄预览界面可以显示扩充比例调整按钮或扩充比例选择列表等。
其中，当用户选择横向扩充按钮时，拍摄预览界面显示两条纵向的调整线，该两条纵向的调整线之间的区域即为第二指定图像区域，用户移动任一条调整线，即可调整第二指定图像区域的大小；当用户选择纵向扩充按钮时，拍摄预览界面显示两条横向的调整线，该两条横向的调整线之间的区域即为第二指定图像区域，用户移动任一条调整线，即可调整第二指定图像区域的大小；当用户选择圆形压缩按钮时，拍摄预览界面显示圆形的调整线，该圆形的调整线之间的区域即为第二指定图像区域，用户调整圆形的半径，即可调整第二指定图像区域的大小。另外，用户可以通过扩充比例调整按钮或通过扩充比例选择列表等，对第二预设比例进行调整。
在本发明的一个具体实施例中，当用户选择横向扩充按钮，并设置第二预设比例为200％，第二指定图像区域内的图像数据与第一指定图像区域内的图像数据相同，即第二指定图像区域内的图像数据如图2所示，此时，在根据预设哈哈镜算法进行扩充处理后第一指定图像区域内的图像数据如图4所示。
在本发明的再一个实施例中，上述预设哈哈镜算法可以包括：将第三指 定图像区域内的像素沿预设方向等分为100份，并分别按顺序依次赋予不同的坐标，其中，每份像素对应坐标的范围为1-100，进而根据预设变换公式对每份像素对应坐标进行变换处理，最后将每份像素移位至变换处理后的坐标。其中，预设方向可以为横向或纵向或圆周方向等。
具体地，预设变换公式具体可以为：
Figure PCTCN2016088886-appb-000001
或
y＝(x/10)2
其中，x为100份像素中任一份像素对应坐标，y为变换处理后的坐标。
需要说明的是，对于预设变换公式
Figure PCTCN2016088886-appb-000002
或y＝(x/10)2，当x的取值范围为0～100时，y的取值范围也是0～100，其中，x的取值范围可以为0～100内的整数或非整数。因此，上述预设哈哈镜算法可以对第三指定图像区域内的图像进行形变，第三指定图像区域内的图像像素不溢出且不减少，不会影响第三指定图像区域外的图像。
例如，在本发明的一个具体实施例中，第三指定图像区域内的图像数据为如图5所示长度均匀的一条彩带，该彩带一共10个颜色。预设哈哈镜算法将第三指定图像区域内的像素沿横向等分为100组，从左到右依次赋予坐标为0至100。预设哈哈镜算法根据
Figure PCTCN2016088886-appb-000003
对每份像素对应坐标进行变换处理，以实现正向压缩形变，那么：
对应坐标为0的一份像素在变换处理后对应的坐标为0；
对应坐标为10的一份像素在变换处理后对应的坐标为32；
对应坐标为20的一份像素在变换处理后对应的坐标为45；
对应坐标为30的一份像素在变换处理后对应的坐标为55；
对应坐标为40的一份像素在变换处理后对应的坐标为63；
对应坐标为50的一份像素在变换处理后对应的坐标为71；
对应坐标为60的一份像素在变换处理后对应的坐标为77；
对应坐标为70的一份像素在变换处理后对应的坐标为84；
对应坐标为80的一份像素在变换处理后对应的坐标为89；
对应坐标为90的一份像素在变换处理后对应的坐标为95；
对应坐标为100的一份像素在变换处理后对应的坐标为100。
所以第三指定图像区域内的彩带经过预设哈哈镜算法处理，处理后的 彩带如图6所示。
在本发明的又一个实施例中，预设哈哈镜算法可以包括：将第四指定图像区域分为第一图像区域和第二图像区域，进而对第一图像区域中的图像数据按第三预设比例进行扩充，同时对第二图像区域中的图像数据按第四预设比例进行压缩。其中，第三预设比例大于0且小于1，第四预设比例大于1。
具体地，当用户打开相机功能后，拍摄预览界面可以显示形变方向选择列表，其中，形变方向选择列表可以包括从左向右形变按钮、从右向左形变按钮、从上向下形变按钮和从下向上形变按钮等，以及拍摄预览界面可以显示矩形或方形或圆形的调整线等，矩形或方形或圆形的调整线之间的的区域即为第四指定图像区域，以及拍摄预览界面可以显示压缩比例调整按钮或压缩比例选择列表等，或拍摄预览界面可以显示扩充比例调整按钮或扩充比例选择列表等。
其中，当用户选择从左向右形变按钮或从右向左形变按钮时，预设哈哈镜算法可以通过纵向分割线将第四指定图像区域分为左部的第一图像区域和右部的第二图像区域，纵向分割线与第四指定图像区域上部外框之间具有第一交点，纵向分割线与第四指定图像区域下部外框之间具有第二交点；当用户选择从上向下形变按钮或从下向上形变按钮时，预设哈哈镜算法可以通过横向分割线将第四指定图像区域分为上部的第一图像区域和下部的第二图像区域，横向分割线与第四指定图像区域左部外框之间具有第三交点，横向分割线与第四指定图像区域右部外框之间具有第四交点。
具体地，用户通过调整矩形或方形或圆形的调整线，即可调整第四指定图像区域的大小，通过设置压缩比例调整按钮或压缩比例选择列表等即可对第三预设比例进行调整，通过设置扩充比例调整按钮或扩充比例选择列表即可对第四预设比例进行调整。
其中，对第一图像区域中的图像数据按第三预设比例进行扩充，同时对第二图像区域中的图像数据按第四预设比例进行压缩包括：
对第一图像区域中的图像数据按预设过渡方式逐级递增进行扩充，同时对第二图像区域中的图像数据按预设过渡方式逐级递增进行压缩。
需要说明的是，对第一图像区域中的图像数据按预设过渡方式逐级递增进行扩充，同时对第二图像区域中的图像数据按预设过渡方式逐级递增进行 压缩，可以保证第四指定图像区域边缘的图像与第四指定图像区域外的图像实现平滑渐变过渡。

需要说明的是，本发明实施例的预设哈哈镜算法可以包括但不仅限于上述四种。
在本发明的一个实施例中，可以将上述四种预设哈哈镜算法中的多种或全部集成到电子设备的相机APP中，此时，第一指定图像区域、第二指定图像区域、第三指定图像区域和第四指定图像区域可以为相同的图像区域或部分为相同的图像区域，从而在拍照时，相机APP可以提供多种哈哈镜效果供用户选择，并可以叠加使用哈哈镜效果，例如可以在对第一指定图像区域内 的图像数据按第一预设比例进行压缩后，和/或再次对第一指定图像区域内的图像数据按第二预设比例进行扩充，和/或再次将第一指定图像区域内的像素沿预设方向等分为100份，并分别按顺序依次赋予不同的坐标，其中，每份像素对应坐标的范围为1-100，进而根据预设变换公式对每份像素对应坐标进行变换处理，最后将每份像素移位至变换处理后的坐标，和/或再次将第一指定图像区域分为第一图像区域和第二图像区域，进而对第一图像区域中的图像数据按第三预设比例进行扩充，同时对第二图像区域中的图像数据按第四预设比例进行压缩。从而极大地提高了用户体验更好。
根据本发明实施例的电子设备实现哈哈镜拍照效果的方法，在运行电子设备的拍摄模式后，获取电子设备的摄像头模组实时取景的每一帧图像数据，并根据预设哈哈镜算法实时对每一帧图像数据进行处理，将处理后的图像数据显示在电子设备的拍摄预览界面。以及在接收拍照指令后，获取摄像头模组采集的图像数据，并根据预设哈哈镜算法对采集的图像数据进行处理，根据处理后的图像数据生成压缩编码图片。从而实现直接从电子设备的相机功能入手，将一种或多种哈哈镜效果引入拍照中，使得用户在拍照时，可以根据需要自由选择哈哈镜效果，且拍摄预览界面和成片直接呈现哈哈镜效果，直观高效，用户体验好；另外，由于在压缩编码前，通过软件系统根据预设哈哈镜算法直接对摄像头模组采集到的图像数据进行处理，可以最大程度保证图片像素不损失。
参照图11，示出了本发明的一种电子设备实现哈哈镜拍照效果的装置实施例的结构框图。该电子设备实现哈哈镜拍照效果的装置可以包括：
运行模块1，运行电子设备的拍摄模式。
其中，当用户打开电子设备的相机功能后，运行模块1运行电子设备的拍摄模式。
显示模块2，用于获取电子设备的摄像头模组实时取景的每一帧图像数据，并根据预设哈哈镜算法实时对每一帧图像数据进行处理，将处理后的图像数据显示在电子设备的拍摄预览界面。
其中，摄像头模组可以包括摄像头、模数转换模块等。具体地，运行模块1后，电子设备的摄像头模组实时取景即摄像头模组接收光信息，并对接 收的光信息进行模数转换等前期处理以获得上述的每一帧图像数据。
通过显示模块2，可以实现在摄像头模组取景时，通过电子设备的软件系统对取景的每一帧图像数据，直接先根据预设哈哈镜算法进行处理之后，再送给电子设备的显示屏显示，从而可以最大程度保证拍摄预览界面例如相机APP的拍摄预览界面中图片像素不损失，且使得用户在拍摄预览界面，就可以实时直观的看到照片的哈哈镜效果，极大地提高了用户体验。
指令接收模块3，用于接收拍照指令。
具体地，当用户根据拍摄预览界面确定所需哈哈镜效果为当前哈哈镜效果后，若用户点击拍摄按钮，指令接收模块3接收拍照指令。
图片生成模块4，用于获取摄像头模组采集的图像数据，并根据预设哈哈镜算法对采集的图像数据进行处理，根据处理后的图像数据生成压缩编码图片。
指令接收模块3后，摄像头模组采集光信息，并对采集的光信息进行模数转换等前期处理后以获得上述采集的图像数据。
其中，在本发明的一个实施例中，当摄像头模组采集到图像数据后，可以缓存该采集的图像数据至系统内存，以便于图片生成模块4可以高效的根据预设哈哈镜算法对采集的图像数据进行处理。
其中，图片生成模块4可以通过电子设备的软件系统，直接根据预设哈哈镜算法对摄像头模组采集且未压缩编码的图像数据进行处理，进而通过电子设备的软件系统，再对处理后的图像数据进行压缩编码为预设格式的图片，该图片为具有用户所需哈哈镜效果的图片。从而可以最大程度保证成片像素不损失，极大地提高了用户体验。具体地，预设格式可以为JPEG格式、GIF格式或PNG格式等格式。
其中，当缓存该采集的图像数据至系统内存后，在图片生成模块4根据处理后的图像数据生成压缩编码图片后，还可以释放该采集的图像数据所占用的系统内存，从而可以提高系统效率。
具体地，在本发明的一个实施例中，上述预设哈哈镜算法可以包括：对第一指定图像区域内的图像数据按第一预设比例进行压缩。
其中，对第一指定图像区域内的图像数据按第一预设比例进行压缩可以为对第一指定图像区域内的图像数据中像素数目按第一预设比例进行压缩， 第一预设比例大于0且小于1。
具体地，当用户打开相机功能后，拍摄预览界面可以显示压缩方向选择列表，压缩方向选择列表可以包括横向压缩按钮、纵向压缩按钮和圆形压缩按钮等，以及拍摄预览界面可以显示压缩比例调整按钮或压缩比例选择列表等。
其中，当用户选择横向压缩按钮时，拍摄预览界面显示两条纵向的调整线，该两条纵向的调整线之间的区域即为第一指定图像区域，用户移动任一条调整线，即可调整第一指定图像区域的大小；当用户选择纵向压缩按钮时，拍摄预览界面显示两条横向的调整线，该两条横向的调整线之间的区域即为第一指定图像区域，用户移动任一条调整线，即可调整第一指定图像区域的大小；当用户选择圆形压缩按钮时，拍摄预览界面显示圆形的调整线，该圆形的调整线之间的区域即为第一指定图像区域，用户调整圆形的半径，即可调整第一指定图像区域的大小。另外，用户可以通过压缩比例调整按钮或通过压缩比例选择列表等，对第一预设比例进行调整。

具体地，当用户打开相机功能后，拍摄预览界面可以显示扩充方向选择列表，扩充方向选择列表可以包括横向扩充按钮、纵向扩充按钮和圆形扩充按钮等，以及拍摄预览界面可以显示扩充比例调整按钮或扩充比例选择列表等。
其中，当用户选择横向扩充按钮时，拍摄预览界面显示两条纵向的调整线，该两条纵向的调整线之间的区域即为第二指定图像区域，用户移动任一条调整线，即可调整第二指定图像区域的大小；当用户选择纵向扩充按钮时，拍摄预览界面显示两条横向的调整线，该两条横向的调整线之间的区域即为第二指定图像区域，用户移动任一条调整线，即可调整第二指定图像区域的大小；当用户选择圆形压缩按钮时，拍摄预览界面显示圆形的调整线，该圆形的调整线之间的区域即为第二指定图像区域，用户调整圆形的半径，即可 调整第二指定图像区域的大小。另外，用户可以通过扩充比例调整按钮或通过扩充比例选择列表等，对第二预设比例进行调整。
在本发明的再一个实施例中，上述预设哈哈镜算法可以包括：将第三指定图像区域内的像素沿预设方向等分为100份，并分别按顺序依次赋予不同的坐标，其中，每份像素对应坐标的范围为1-100，进而根据预设变换公式对每份像素对应坐标进行变换处理，最后将每份像素移位至变换处理后的坐标。其中，预设方向可以为横向或纵向或圆周方向等。
具体地，预设变换公式具体可以为：
Figure PCTCN2016088886-appb-000004
或
y＝(x/10)2
其中，x为100份像素中任一份像素对应坐标，y为变换处理后的坐标。
需要说明的是，对于预设变换公式
Figure PCTCN2016088886-appb-000005
或y＝(x/10)2，当x的取值范围为0～100时，y的取值范围也是0～100，其中，x的取值范围可以为0～100内的整数或非整数。因此，上述预设哈哈镜算法对第三指定图像区域内的图像进行形变时，第三指定图像区域内的图像像素不溢出且不减少，不会影响第三指定图像区域外的图像。
在本发明的又一个实施例中，预设哈哈镜算法可以包括：将第四指定图像区域分为第一图像区域和第二图像区域，进而对第一图像区域中的图像数据按第三预设比例进行扩充，同时对第二图像区域中的图像数据按第四预设比例进行压缩。其中，第三预设比例大于0且小于1，第四预设比例大于1。

其中，对第一图像区域中的图像数据按第三预设比例进行扩充，同时对第二图像区域中的图像数据按第四预设比例进行压缩包括：
对第一图像区域中的图像数据按预设过渡方式逐级递增进行扩充，同时对第二图像区域中的图像数据按预设过渡方式逐级递增进行压缩。
需要说明的是，对第一图像区域中的图像数据按预设过渡方式逐级递增进行扩充，同时对第二图像区域中的图像数据按预设过渡方式逐级递增进行压缩，可以保证第四指定图像区域边缘的图像与第四指定图像区域外的图像实现平滑过渡。
具体地，当用户打开相机功能后，拍摄预览界面可以显示过渡方式选择列表，其中，过渡方式选择列表可以包括直线过渡按钮、二次函数过渡按钮或圆弧过渡按钮等。其中，当用户选择直线过渡按钮时，拍摄预览界面显示第一过渡直线和第二过渡直线；当用户选择二次函数过渡按钮时，拍摄预览界面显示第一过渡弧线和第二过渡弧线；当用户选择二次函数过渡按钮时，拍摄预览界面显示过渡圆弧。

需要说明的是，本发明实施例的预设哈哈镜算法可以包括但不仅限于上述四种。
在本发明的一个实施例中，可以将上述四种预设哈哈镜算法中的多种或全部集成到电子设备的相机APP中，此时，第一指定图像区域、第二指定图像区域、第三指定图像区域和第四指定图像区域可以为相同的图像区域或部分为相同的图像区域，从而在拍照时，相机APP可以提供多种哈哈镜效果供用户选择，并可以叠加使用哈哈镜效果，例如可以在对第一指定图像区域内的图像数据按第一预设比例进行压缩后，和/或再次对第一指定图像区域内的图像数据按第二预设比例进行扩充，和/或再次将第一指定图像区域内的像素沿预设方向等分为100份，并分别按顺序依次赋予不同的坐标，其中，每份像素对应坐标的范围为1-100，进而根据预设变换公式对每份像素对应坐标进行变换处理，最后将每份像素移位至变换处理后的坐标，和/或再次将第一指定图像区域分为第一图像区域和第二图像区域，进而对第一图像区域中的图像数据按第三预设比例进行扩充，同时对第二图像区域中的图像数据按第四预设比例进行压缩。从而极大地提高了用户体验更好。
