具体实施方式
下面将结合本公开实施例中的附图，对本公开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公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，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，都属于本公开保护的范围。
如图1所示，为本公开的实施例中拍照方法的步骤流程图，该方法包括如下步骤：
步骤101：在第一预览界面显示摄像头采集的第一预览图像的状态下，接收用户在第一预览界面上选取目标区域的第一输入。
在本步骤中，具体的，摄像头采集的第一预览图像为摄像头实时采集的、显示在第一预览界面上的图像。此外，第一输入包括用户在第一预览界面上输入的预设图形轨迹或者图像轮廓的勾勒轨迹，其中，预设图形轨迹所包括的区域为目标区域。具体的，预设图形轨迹可以为矩形、圆形等图形轨迹。当然，图像轮廓的勾勒轨迹所包括的区域同样为目标区域。
这样，通过接收用户在第一预览界面上选取目标区域的第一输入，使得移动终端能够针对该第一输入做出响应。
例如，如图2所示，当在第一预览界面21显示第一预览图像时，若用户2想要基于该第一预览图像进行拍照，则可以在该第一预览界面21上输入选取目标区域的第一输入，该第一输入可以包括矩形图形轨迹22，且该矩形图形轨迹22所包括的区域为目标区域。再例如，如图3所示，当在第一预览界 面31显示第一预览图像时，若用户3想要基于该第一预览图像进行拍照，则可以在该第一预览界面31上输入选取目标区域的第一输入，该第一输入可以为在第一预览界面中输入的图像轮廓的勾勒轨迹32，当然该勾勒轨迹32所包括的区域为目标区域。
步骤102：响应于第一输入，在第一预览界面上叠加显示第二预览界面，第二预览界面显示目标区域的第二预览图像。
在本步骤中，具体的，在接收到第一输入之后，可以响应于第一输入，在第一预览界面上叠加显示第二预览界面，其中第二预览界面显示有目标区域中的第二预览图像。这使得响应于第一输入得到的图像包括叠加的显示有第一预览图像的第一预览界面和显示有第二预览图像的第二预览界面，即使得响应于第一输入后所得图像具有两个层次，实现了在拍照过程中得到具有多个层次的图像，并突出显示了用户从第一预览界面中选择的第二预览图像。
其中，第一预览界面包括第一预览图像显示区，第一预览图像显示区中显示第一预览图像；第二预览界面包括第二预览图像显示区，第二预览图像显示区显示第二预览图像；其中，第二预览界面包括预先存储的边框区域图像，边框区域图像包括移动终端的边框图像和第一预览界面中除第一预览图像之外的控件区域图像所组成的图像，第二预览图像位于边框区域图像的显示范围内。这样，使得第二预览界面的显示形式与第一预览界面的显示形式类似，实现了图中图的拍摄效果，增加了拍摄所得图像的层次感。
例如，参见图4所示，可以在图2中显示有第一预览图像的第一预览界面21上叠加显示第二预览界面41，其中，第二预览界面41中显示有图2中目标区域中的第二预览图像23。其中，第二预览界面41包括边框区域图像42，该边框区域图像可以包括移动终端的边框图像和第一预览界面中除第一预览图像之外的控件区域图像所组成的图像，且图2中目标区域内的第二预览图像23显示于边框区域图像的显示范围内，这增加了第二预览界面与第一预览界面的相似度，实现了图中图的拍摄效果，进一步增加了所显示图像的层次感。当然，在图3中显示有第一预览图像的第一预览界面31上叠加显示第二预览界面时，与在图2中的第一预览界面21上叠加显示第二预览界面的方式相同，在此不在进行具体说明。
当然，第一预览界面还可以包括控件显示区，以使用户能够在控件显示区上对控件输入操作，从而实现在拍摄过程中对图像的操作。
步骤103：接收用户的第二输入。
在本步骤中，具体的，第二输入包括对移动终端拍照按键的点击操作或者对移动终端显示屏幕上任一位置的长按操作。当然在此并不具体限定第二输入的具体形式。这样通过接收用户的第二输入，使得移动终端可以根据该第二输入执行拍照操作。
步骤104：响应于第二输入，执行拍照操作，输出目标图像。
在本步骤中，具体的，当移动终端接收到第二输入时，可以响应于第二输入，执行拍照操作，输出目标图像。其中，目标图像为基于第一预览界面和第二预览界面显示的图像内容生成的合成图像。这使得拍照所得的目标图像包括第一预览界面和第二预览界面所显示的图像，从而使得拍照所得照片内的图像具有两个层次，实现了在拍照过程中拍摄得到具有多个层次图像的照片，增加了照片的层次感。
其中，合成图像可以包括第一预览图像和第二预览图像，且第二预览图像的外侧包括第一边框区域图像；或者，合成图像包括第一预览图像和第二预览图像，且第一预览图像的外侧包括第二边框区域图像，第二预览图像的外侧包括第三边框区域图像。具体的，外侧指预览图像的周围区域，即第一预览图像的周围区域为第二边框区域图像；或者，第一预览图像的周围区域为第二边框区域图像，第二预览图像的周围区域为第三边框区域图像。
这样，通过在合成图像中第二预览图像的外侧包括第一边框区域图像，或者第一预览图像的外侧包括第二边框区域图像，第二预览图像的外侧包括第三边框区域图像，使得第一预览图像的外侧即可以有边框区域图像，也可以没有边框区域图像，实现了用户能够从两种拍照效果中进行选择，增加了用户在拍照时对拍照效果的选择性。
本实施例通过在第一预览界面显示摄像头采集的第一预览图像的状态下，接收用户在第一预览界面上选取目标区域的第一输入，然后响应于第一输入，在第一预览界面上叠加显示包括目标区域的第二预览图像的第二预览界面，然后接收用户的第二输入，响应于第二输入，执行拍照操作，输出目标图像， 其中目标图像为基于第一预览界面和第二预览界面显示的图像内容生成的合成图像，使得拍照所得的目标图像包括第一预览界面和第二预览界面显示的图像内容生成的合成图像，即能够在照片中得到具有第一预览界面和第二预览界面两个层次的图像内容，实现了在拍照过程中拍摄出具有多个层次的图像。
进一步地，在本实施例中用户可以选取多个目标区域，从而使得第一预览界面上可以叠加显示多个第二预览界面，进而使得拍摄所得图像能够呈现较多的图像内容，进一步地增加拍摄所得图像的层次，实现拍摄所得图像的多元化和层次化。具体的，实现过程可以如下：
第一输入所选取的目标区域的个数为N，N大于1；此时在响应于第一输入，在第一预览界面上叠加显示第二预览界面，第二预览界面显示目标区域的第二预览图像的步骤中，响应于第一输入，在第一预览界面上叠加显示N个第二预览界面，N个第二预览界面分别显示每个目标区域的预览图像；其中，输出的目标图像为基于第一预览界面、N个第二预览界面显示的图像内容生成的合成图像。
这样使得用户能够在第一预览界面上指定多个不同的目标区域，从而使得能够在第一预览界面上叠加生成多个第二预览界面，且每个第二预览界面上显示一个目标区域内的预览图像，实现了拍照所得图像的第二预览界面上能够突出显示多个用户选择的图像。
例如，如图5所示，在第一预览界面51上显示有摄像头实时采集的第一预览图像时，若用户5需要基于实时采集的第一预览图像在第一预览界面51上叠加显示多个第二预览界面，则用户5可以通过第一输入选取多个目标区域，例如可以为2个目标区域。具体的，第一输入为图像轮廓的勾勒轨迹。例如用户5可以在图5所示的第一预览界面51中输入2个图像轮廓的勾勒轨迹52，此时勾勒轨迹52所包括的范围为目标区域。
此时，移动终端在接收到该第一输入之后，参见图6，可以在图5中的第一预览界面51上叠加显示两个第二预览界面61，其中，该两个第二预览界面61中分别显示有图5中目标区域中的第二预览图像53，从而使得在响应于第二输入后得到图像上的第一预览界面上能够叠加显示多个第二预览界 面，且每个第二预览界面上显示有用户选定的第二预览图像。具体的，该两个第二预览界面可以均包括边框区域图像62，其中边框区域图像62可以包括移动终端的边框图像，且图5中目标区域内的第二预览图像53显示于边框区域图像的显示范围内。这增加了第二预览界面与第一预览界面的相似度，实现了图中图的效果，进一步增加了所显示图像的层次感。
此外，进一步地，在响应于第一输入，在第一预览界面上叠加显示第二预览界面之后，还可以对第一预览界面和第二预览界面进行不同的操作，从而使得拍照得到的目标图像能够更符合用户的需求。下面，对此进行介绍。
其一，若第一输入为用户勾勒第一预览图像中的目标对象的轮廓的操作，目标区域为包括目标对象的预设范围的预览图像区域，则在响应于第一输入，在第一预览界面上叠加显示第二预览界面之后，可以包括以下至少一项：对第一预览图像中除目标区域之外的所有图像区域进行虚化处理；对第二预览图像中除目标对象之外的所有图像区域进行虚化处理。
这样，使得可以得到只有第一预览图像中除目标区域之外的所有图像区域进行虚化处理的处理效果，只有第二预览图像中除目标对象之外的所有图像区域进行虚化处理的处理效果，以及第一预览图像中除目标区域之外的所有图像区域和第二预览图像中除目标对象之外的所有图像区域均进行虚化处理的处理效果，从而使得用户能够针对虚化处理具有多种选择，增加了用户在进行虚化处理时的选择性。
具体的，在对第一预览图像中除目标区域之外的所有图像区域进行虚化处理时，可以在第一预览图像中除目标区域之外的所有图像区域中的任意位置输入第一操作，该第一操作包括长按或双击操作，以使移动终端对除目标区域之外的所有图像区域进行虚化处理。此外，在对第二预览图像中除目标对象之外的所有图像区域进行虚化处理时，可以在第二预览图像中除目标图像之外的所有图像区域输入第二操作，该第二操作可以为长按或双击操作，以使移动终端对除目标对象之外的所有图像区域进行虚化处理。
其二，在响应于第一输入，在第一预览界面上叠加显示第二预览界面之后，还可以接收用户在预设操作控制区的第三输入；响应于第三输入，按照第三输入的操作方向，移动第二预览界面；其中，在第二预览界面移动过程 中，第二预览界面实时显示第一预览图像中与第二预览界面的预览图像显示区相对应的对应区域的预览图像。
这样，用户通过输入第三输入，能够移动第二预览界面，此时第二预览界面实时显示第一预览图像中与第二预览界面的预览图像显示区域相对应的对应区域的预览图像，实现了实时更新第二预览界面内所显示的图像，方便了用户确定第二预览界面中所显示的图像。
具体的，在按照第三输入的操作方向，移动第二预览界面时，第二预览界面的移动方向可以与第三输入的操作方向相一致，从而为用户的操作提供便利。例如，当第三输入的操作方向为第一方向时，第二预览界面的移动方向为第一方向，当第三输入的操作方向为第二方向时，第二预览界面的移动方向为第二方向，从而使得能够通过第三输入的操作方向，在第二预览界面上实时显示相同方向的第一预览界面上的图像内容，方便了用户的操作。
其三，在响应于第一输入，在第一预览界面上叠加显示第二预览界面之后，还可以接收用户在预设操作控制区的第四输入；响应于第四输入，对第二预览界面进行缩放；其中，在第二预览界面缩放过程中，第二预览界面实时显示第一预览图像中与第二预览界面的预览图像显示区相对应的对应区域的预览图像。
这样，用户通过输入第四输入，能够对第二预览界面的尺寸进行调节，此时第二预览界面实时显示第一预览图像中与调节后的第二预览界面的预览图像显示区域相对应的对应区域的预览图像，实现了实时更新第二预览界面内所显示的图像，方便了用户确定第二预览界面中所显示的图像。
具体的，第四输入可以为缩放控制操作，该缩放控制操作可以包括用户的至少两个手指在移动终端上的扩张操作和收缩操作。其中，在缩放控制操作为用户的至少两个手指在移动终端上的扩张操作时，第二预览界面进行放大；在缩放控制操作为用户的至少两个手指在移动终端上的收缩操作时，第二预览界面进行缩小。这使得第二预览界面的缩放能够与用户输入的缩放控制操作相一致，从而使得用户能够根据第二预览界面的需求尺寸确定第四输入，方便了用户的操作。
其四，响应于第一输入，在第一预览界面上叠加显示第二预览界面之后， 还包括以下至少一项：在接收到用户的第五输入的情况下，响应于第五输入，调节第一预览图像的图像参数；在接收到用户的第六输入的情况下，响应于第六输入，调节第二预览图像的图像参数；在接收到用户的第七输入的情况下，响应于第七输入，调节第一预览图像和第二预览图像的图像参数，其中，第七输入用于调节第一预览图像和第二预览图像的同一图像参数。具体的，第五输入包括在第一预览界面上的第一预设控件的点击操作，第六输入包括在第一预览界面上的第二预设控件的点击操作，第七输入包括在第一预览界面上的第三预设控件的点击操作。此外，具体的，图像参数可以包括滤镜、图像美化等级和图像颜色的饱和度等，在此并不具体限定图像参数的具体内容。
这样，用户通过输入不同的输入操作，能够单独调节第一预览图像或第二预览图像的图像参数，还可以同时调节第一预览图像和第二预览图像的图像参数，使得为用户对目标图像的图像参数进行调节提供了多种选择，增加了用户在调节图像参数时的选择性，且操作便捷。
