智能手机等移动终端已经不再是简单的通信工具，而是集休闲、娱乐和通信等功能的工艺品。与此同时，用户对拍照效果的要求也越来越高。现有技术中，人们采用移动终端进行拍照，通常只能选取一个焦点，拍照得到一张在焦点区域内较为清楚的照片，这也是人们拍照过程中经常会遭遇的景深大小的问题。例如，在这样一个场景下拍照：一个人，一丛花，人与花在移动终端的前后相隔一定的距离；如果人距离移动终端较前而花距离移动终端较远，这时，如果选择人为焦点区域，则花在呈现在照片上是模糊，而如果选择花的所在区域为焦点区域，则人在呈现在照片上是模糊。Mobile terminals such as smart phones are no longer simple communication tools, but handicrafts that integrate leisure, entertainment and communication functions. At the same time, users have higher and higher requirements for camera effects. In the prior art, people use mobile terminals to take pictures, usually only one focal point can be selected, and a photo that is relatively clear in the focal area can be obtained by taking pictures, which is also the problem of depth of field that people often encounter in the process of taking pictures. For example, take a picture in such a scene: a person, a bunch of flowers, the person and the flower are separated by a certain distance in front of the mobile terminal; if the person is farther away from the mobile terminal and the flower is farther away from the mobile terminal, If the focus area is selected, the flowers will appear blurred in the photo, and if the area where the flower is located is selected as the focus area, the person will appear blurred in the photo.

It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
实施例一Embodiment one
参照图1，示出了本发明实施例的一种图像处理方法实施例的步骤流程图，所述移动终端包括多个摄像头；具体可以包括如下步骤：Referring to FIG. 1 , it shows a flow chart of the steps of an embodiment of an image processing method according to an embodiment of the present invention. The mobile terminal includes multiple cameras; specifically, the following steps may be included:
步骤101，接收用户的拍照请求；Step 101, receiving a photo taking request from a user;
本发明实施例中，移动终端可以包括多个摄像头的智能设备，采用所述移动终端进行拍照，首先接收用户触发的拍照请求，其中，用户触发拍照请求的方式可以通过接触屏幕的点击事件，也可以是通过按压实体按键的按压事件，本发明实施例对此不作任何的限制。In the embodiment of the present invention, the mobile terminal may include a smart device with multiple cameras, and the mobile terminal is used to take pictures. First, it receives a photo request triggered by the user. It may be a pressing event of pressing a physical key, which is not limited in this embodiment of the present invention.
步骤102，针对所述拍照请求采用多个摄像头拍摄多张图片；其中，所述多张图片为所述多个摄像头通过不同的焦平面拍摄得到；Step 102, using a plurality of cameras to take a plurality of pictures in response to the photographing request; wherein, the plurality of pictures are obtained by the plurality of cameras through different focal planes;
具体而言，针对所述拍照请求，移动终端采用预先设置的焦距参数调节多个摄像头，获取不同焦平面的多张图片，例如，取焦距参数的范围为10mm-35mm将焦距参数平均分成多份，得到多个不同的焦距参数，采用上述不同焦距参数的设置多个摄像头，同时采用取景框(移动终端的屏幕)上随机不同的点作为焦点信息，采用所述焦点信息进一步设置多个摄像头，而移动终端的摄像头的快门时间、光圈大小、增益等可以取固定值，比如，取快门时间为1/30s，光圈大小F2.8，增益为400，当然，上述的参数设置方式只是本发明实施例的枚举，还可以是其它的参数设置方式，例如，焦距参数的范围以等差数列的方式划分为N个不同的焦距参数，按照取景框的对角线上的点作为焦点，本发明实施例对此不作限制。Specifically, for the photographing request, the mobile terminal uses preset focal length parameters to adjust multiple cameras to obtain multiple pictures of different focal planes. , to obtain a plurality of different focal length parameters, adopt the above-mentioned different focal length parameters to set multiple cameras, and use random different points on the viewfinder frame (screen of the mobile terminal) as focus information, and further set multiple cameras by using the focus information, The shutter time, aperture size, gain, etc. of the camera of the mobile terminal can take fixed values. For example, the shutter time is 1/30s, the aperture size is F2.8, and the gain is 400. Of course, the above-mentioned parameter setting method is only the implementation of the present invention. The enumeration of example can also be other parameter setting methods, for example, the scope of the focal length parameter is divided into N different focal length parameters in the mode of arithmetic sequence, according to the point on the diagonal line of the viewfinder frame as the focus, the present invention The embodiment does not limit this.
经过上述的焦距参数、焦点信息设置及快门时间、光圈大小、增益的设置，移动终端采用设置了不同参数的N个摄像头拍照后，获得不同焦平面的N张图片，需要说明的是，焦平面指的是与成像系统的光轴垂直且包含成像系统焦点的平面，参照图2，示出本发明实施例的一种焦平面的图片，与焦点同一平面上且与移动终端的摄像头的感光器件(CCD，Charge-coupled Device)平行的为同一焦平面，即拍照时在同一焦平面的物象应该都是清晰的，如图2中的物象“蝴蝶”因为都在同一焦平面上，获得的图片中“蝴蝶”都是清晰的，而不在焦平面内的背景与前景都是模糊的(虚化的)。获得不同焦平面的多张图片，即获得多张有不同的清晰的物象的图片，需要说明的是，本发明实施例中，焦距参数大小的设置方式，可以将焦距参数限制在一个较小的范围内，例如取焦距参数范围为18mm-22mm，将上述的焦距范围平均分为N份，采用取景框上不同的随机点为焦点信息，这样，可以得到多张焦平面较近的图片。After the above-mentioned focal length parameter, focus information setting, and shutter time, aperture size, and gain setting, the mobile terminal adopts N cameras with different parameters to take pictures, and obtains N pictures of different focal planes. It should be noted that the focal plane Refers to the plane perpendicular to the optical axis of the imaging system and containing the focal point of the imaging system. Referring to FIG. 2 , it shows a picture of a focal plane according to an embodiment of the present invention. (CCD, Charge-coupled Device) are parallel to the same focal plane, that is, the objects on the same focal plane should be clear when taking pictures, as shown in Figure 2. Because the object image "butterfly" is on the same focal plane, the obtained picture The "butterflies" in the medium are clear, while the background and foreground that are not in the focal plane are blurred (blurred). Obtain multiple pictures of different focal planes, that is, obtain multiple pictures with different clear object images. It should be noted that, in the embodiment of the present invention, the setting method of the focal length parameter can limit the focal length parameter to a smaller Within the range, for example, the focal length parameter range is 18mm-22mm, and the above-mentioned focal length range is divided into N parts on average, and different random points on the viewfinder frame are used as the focus information. In this way, multiple pictures with closer focal planes can be obtained.
步骤103，分别提取所述多张图片中的拍摄主体和背景层；Step 103, respectively extracting the subject and the background layer in the plurality of pictures;
步骤104，将所述多张图片的背景层合成为背景图片；Step 104, synthesizing the background layers of the multiple pictures into a background picture;
实际而言，因为在焦距参数在一个较小的焦距参数范围内波动，且每个摄像头所取的焦点不同，得到的多张图片对应拍摄主体的焦平面是相近的，故多张图片的拍摄主体可以认为是相近的，只是相对于不同图片的不同拍摄主体之间具有模糊与清晰的区别，例如，图片A与图片B，图片A与移动终端的镜头的距离较近，图片B与移动终端的镜头的距离较远，可以认为在拍摄图片B时，图片A的拍摄主体是模糊的，因为在拍摄图片B时，只有在图片B所处的焦平面的拍摄主体是清晰的，其中，所述拍摄主体包括人像和物像，本发明实施例中，通过DSP(Digital Signal Processing，数字信号处理器)或移动终端的CPU的处理，获得所述N张图片的拍摄主体，其中，所述拍摄主体可以包括人像和物像。In practice, because the focal length parameter fluctuates within a small focal length parameter range, and the focal points taken by each camera are different, the focal planes of the obtained multiple pictures corresponding to the subject are similar, so the shooting of multiple pictures The subjects can be considered to be similar, but there are blurred and clear differences between different photographed subjects in different pictures, for example, picture A and picture B, the distance between picture A and the lens of the mobile terminal is relatively short, and the distance between picture B and the mobile terminal The distance of the lens is relatively far, it can be considered that when taking picture B, the subject of picture A is blurred, because when taking picture B, only the subject at the focal plane of picture B is clear, wherein, all The photographed subjects include portraits and object images. In the embodiment of the present invention, the photographed subjects of the N pictures are obtained through DSP (Digital Signal Processing, Digital Signal Processing) or CPU processing of the mobile terminal, wherein the photographed Subjects can include portraits and objects.
具体应用到本发明实施例中，将所述多张图片的背景层合成为背景图片，提取出多张图片的背景层后，将所述多张图片的背景层按照图片的位置信息进行合成操作，得到背景图片，具体而言，因为所述多张是在不同的焦距范围内拍摄的多张图片，图片的背景层不会有较大的差别，只是不同的景深信息对应不同的清晰区域的背景层，本发明实施例中，将不同的景深信息对应不同的清晰区域的背景层合成为背景图片，因为第一摄像头及第二摄像头可以用测量得到拍摄主体的距离，进一步地，根据距离可以获得图片的景深信息。Specifically applied to the embodiment of the present invention, the background layers of the multiple pictures are synthesized into a background picture, and after the background layers of the multiple pictures are extracted, the background layers of the multiple pictures are synthesized according to the position information of the pictures , to get the background picture, specifically, because the multiple pictures are taken in different focal length ranges, the background layer of the picture will not have a big difference, but the different depth of field information corresponds to different clear areas The background layer, in the embodiment of the present invention, the background layer with different depth information corresponding to different clear areas is synthesized into a background picture, because the first camera and the second camera can be used to measure the distance of the subject, and further, according to the distance can be Get the depth of field information of the image.
步骤105，将所述拍摄主体合成至背景图片，获得目标图片。In step 105, the subject is synthesized into a background picture to obtain a target picture.
本发明实施例中，获取多个拍摄主体及背景图片后，可以对背景图片中的拍摄主体进行识别，再将所述多个个拍摄主体与背景图片中的拍摄主体进行对比，提取特征像素点，将特征像素点添加到所述背景图片中，获得目标图片。In the embodiment of the present invention, after obtaining multiple subjects and background pictures, the subjects in the background picture can be identified, and then the multiple subjects can be compared with the subjects in the background picture to extract feature pixels , adding feature pixels to the background image to obtain the target image.
