本申请实施例提出了一种图像处理方法，请参见图1，该方法具体包括以下步骤：
步骤S101，获取终端的预览界面中的预览图像的属性信息。
当用户打开终端的相机APP(Application，应用程序)时，终端的摄像头将获取该摄像头取景范围内的图像，并在终端的预览界面上显示所获取的预览图像；其中，终端可以包括但不限于手机、平板电脑等。为了分析预览图像的拍摄场景，需要获取该预览图像的属性信息。预览图像的属性信息可以包括但不限于色彩值、亮度值、景深等，其中，各属性信息都采用数值形式表示，并包含在一定的取值范围内；例如，色彩值采用数值形式表示，其取值范围为0～255。
步骤S102，根据所述预览图像的属性信息确定所述终端的拍摄场景。
根据预览图像的属性信息可以获取拍摄场景的配置信息，从而确定所述终端的拍摄场景。其中，所述终端的拍摄场景为终端当前的拍摄场景。例如，终端当前处于自然环境中，则终端当前的拍摄场景可以是风景拍摄场景。所述拍摄场景的配置信息存储于场景数据库中，该场景数据库包括至少一个拍摄场景的标识及各拍摄场景的配置信息，各拍摄场景的配置信息可以包括但不限于色彩范围、亮度范围及景深范围等。例如，所述场景数据库存储的部分内容如表1所示。
表1：场景数据库
| 拍摄场景的标识 | 拍摄场景的配置信息 | ||
| 色彩范围 | 亮度范围 | 景深范围 | |
| 风景拍摄场景 | 10-200 | 10-150 | 10-50 |
| 人物拍摄场景 | 50-150 | 50-150 | 5-20 |
| 夜间拍摄场景 | 10-50 | 10-50 | 10-50 |
| 室内拍摄场景 | 10-100 | 50-100 | 5-10 |
可以理解的是，该场景数据库被预先存储于终端的存储空间，或者云端的存储空间中。根据上述表1的内容，将预览图像的属性信息与各拍摄场景的配置信息分别进行比较，可以确定预览图像的属性信息属于哪一种拍摄场景的配置信息的取值范围内，则可以确定终端当前的拍摄场景。
步骤S103，获取与所述终端的拍摄场景相适配的目标示例图片。
确定终端的拍摄场景后，获取与终端的拍摄场景相适配的目标示例图片，该目标示例图片可以作为拍摄构图的参考图片。其中，拍摄构图可以参考多种构图模式，例如平衡式构图模式、垂直式构图模式、黄金比例构图模式等。在不同的构图模式下，可以包括一张或多张示例图片，其中，所述目标示例图片为目标构图模式下的目标示例图片。所述构图模式、每种构图模式适配的拍摄场景的标识及每种构图模式下的示例图片存储于构图数据库中。例如，所述构图数据库存储的部分内容如表2所示：
表2：构图数据库
| 拍摄场景的标识 | 构图模式 | 构图模式的示例图片 |
| 风景拍摄场景 | 平衡式构图模式 | 图1 |
| 垂直式构图模式 | 图2 | |
| 人物拍摄场景 | 垂直式构图模式 | 图2 |
| 黄金比例构图模式 | 图3、图4 | |
| 夜间拍摄场景 | 平衡式构图模式 | 图1 |

| 三角式构图模式 | 图5、图6 | |
| 室内拍摄场景 | 垂直式构图模式 | 图2 |
可以理解的是，该构图数据库被预先存储于终端的存储空间，或者云端的存储空间中。可以理解的是，目标构图模式可以为一种或多种构图模式，目标示例图片为目标构图模式下的任意一张示例图片。根据所述终端的拍摄场景的标识，可以在构图数据库中查询对应的目标构图模式及目标构图模式下的目标示例图片。
步骤S104，在所述终端的预览界面中输出所述目标示例图片。
确定目标示例图片后，在终端的预览界面中显示该目标示例图片以指导用户进行更美观的拍摄构图。具体实现中，由于终端的预览界面既要显示摄像头的取景范围内的图像，又要显示该目标示例构图，则可以将预览界面进行划分。在预览界面中划分的一个用于进行构图提示的区域，并在该提示区域中显示目标示例图片供用户参考。
本申请实施例中，获取终端的预览界面中的预览图像的属性信息；根据所述预览图像的属性信息确定所述终端的拍摄场景；获取与所述终端的拍摄场景相适配的目标示例图片；在所述终端的预览界面中输出所述目标示例图片；可见，实施本申请实施例，能够在用户拍摄前提供不同构图模式下的示例图片以指导用户拍摄更美观的图片，增强终端的拍摄辅助功能。
参照图2，图2为本申请图像处理方法另一种实施例的流程示意图。
本实施例中，所述图像处理方法包括以下步骤：

a3，若是，根据预览图像的景深值判断所述景深值是否包含于一种拍摄场景的景深范围内；
a4，若是，确定该拍摄场景为所述终端的拍摄场景。
上述步骤a1-a4中，将预览图像的属性信息分别从场景数据库中各拍摄场景的配置信息进行比对，从而确定终端的拍摄场景；例如：预览图像的属性信息包括：色彩值150，亮度值100，景深50；根据上述表1可知该预览图像的色彩值、亮度值及景深均位于风景拍摄场景的配置信息所定义的范围，因此终端当前的拍摄为风景拍摄场景。
步骤S203，获取与所述终端的拍摄场景相适配的目标示例图片。
具体实现中，步骤S203包括以下步骤b1-b3：
b1，获取构图数据库，所述构图数据库包括至少一种构图模式、每种构图模式适配的拍摄场景的标识及每种构图模式下的至少一张示例图片；
b2，根据终端的拍摄场景的标识从构图数据库中查找与所述终端的拍摄场景相适配的目标构图模式；
b3，从所述构图数据库中获取所述目标示例图片。
上述步骤b1-b3中，根据终端的拍摄场景的标识，可以从构图数据库中获取与终端的拍摄场景标识相适配的目标构图模式及目标示例图片；例如，终端的拍摄场景标识为风景拍摄场景，从构图数据库中获取与终端的拍摄场景标识相适配的目标构图模式包括平衡式构图模式及垂直式构图模式，获取目标示例图片包括图1及图2。
步骤S204，在所述终端的预览界面中输出所述目标示例图片。本实施例的步骤S204可参考图1所示的步骤s104，在此不赘述。
步骤S205，若检测到拍摄事件，按照所述目标构图模式存储所述预览界面当前显示的预览图像。
在预览界面显示所述目标示例图片后，终端将检测用户是否进行拍摄。其中，目标示例图片用于为用户提供一种直观的构图模式展示，实际拍摄时需要进行目标构图模式的设置。在一种可行的实施方式中，检测用户是否进行拍摄之前，需要先判断终端是否已加载目标构图模式，从而调用所述目标构图模式进行拍照构图；若未加载，则在终端加载所述目标构图模式。具体实现中，判断终端存储的构图数据库是否包括所述目标构图模式，若不包括，则从云端存储的构图数据库中下载所述目标构图模式。
当目标构图模式包括两种或两种以上的构图模式时，按照所述目标构图模式存储所述预览界面当前显示的预览图像，具体包括以下两种情况：终端随机选择一种构图模式作为目标构图模式，或者用户选择一种构图模式作为目标构图模式。对应于上述第一种情况，步骤S205具体包括以下步骤c1-c2：
c1，若检测到拍摄事件，从所述目标构图模式中随机选择一种构图模式；
c2，按照随机选择的构图模式存储所述预览界面当前显示的预览图像。
对应于上述第二种情况，步骤S205具体包括以下步骤d1-d2：
d1，若检测到拍摄事件，接收用户从所述目标构图模式中选择一种构图模式的指令；
d2，按照用户选择的构图模式存储所述预览界面当前显示的预览图像。
