具体实施方式Detailed ways
本申请提供了一种图像处理方法和装置，以提高图像摄取的灵活度，提高用户与他人或景物合影的便捷性。The present application provides an image processing method and device to improve the flexibility of image capture and the convenience for users to take pictures with other people or scenes.
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.
参见图1，其示出了本申请一种图像处理方法一个实施例的流程示意图，本实施例的方法可以包括：Referring to Fig. 1, it shows a schematic flow chart of an embodiment of an image processing method of the present application, the method of this embodiment may include:
101，当检测到预设指令时，启动电子设备的第一摄像头和第二摄像头的图像采集功能。101. When a preset instruction is detected, start an image acquisition function of a first camera and a second camera of an electronic device.
其中，该第一摄像头与所述第二摄像头分别处于该电子设备的两个相互平行的面板上。即，该第一摄像头与第二摄像头的图像采集区域不重叠，如以手机为例，该第一摄像头和第二摄像头可以分别为该手机的前摄像头和后摄像头。Wherein, the first camera and the second camera are respectively located on two panels parallel to each other of the electronic device. That is, the image acquisition areas of the first camera and the second camera do not overlap. Taking a mobile phone as an example, the first camera and the second camera may be the front camera and the rear camera of the mobile phone respectively.
其中，该预设指令可以根据需要设定，该预设指令用于触发电子设备控制开启该第一摄像头和第二摄像头，使得第一摄像头在其摄像范围内进行图像采集的同时，该第二摄像头也同样在其摄像范围内进行图像采集Wherein, the preset instruction can be set according to needs, and the preset instruction is used to trigger the electronic device to control to turn on the first camera and the second camera, so that while the first camera is collecting images within its imaging range, the second The camera also performs image acquisition within its camera range
如，该预设指令可以为开启电子设备的摄像头。例如，以手机为例，可以是点击手机上的相机图标，触发电子设备开启摄像头。For example, the preset instruction may be to turn on the camera of the electronic device. For example, taking a mobile phone as an example, clicking a camera icon on the mobile phone may trigger the electronic device to turn on the camera.
又如，该预设指定也可以是触按该电子设备预置的指定按键。例如，在该第一摄像头和第二摄像头均未被开启的情况下，当触按该指定按键后，则同时开启该第一摄像头和第二摄像头；也可以是在第一摄像头和第二摄像头中的一个摄像头开启后，如果触按该指定按键，则控制该第一摄像头和第二摄像头同时处于开启状态。As another example, the preset designation may also be pressing a preset designated button of the electronic device. For example, when the first camera and the second camera are not turned on, when the specified button is pressed, the first camera and the second camera are turned on at the same time; After one of the cameras is turned on, if the designated button is pressed, the first camera and the second camera are controlled to be turned on at the same time.
102，获取该第一摄像头采集到的第一预览图像，以及该第二摄像头采集到的第二预览图像。102. Acquire a first preview image captured by the first camera and a second preview image captured by the second camera.
在检测到图像摄取指令之前，该第一摄像头和第二摄取头可以采集图像，但此时采集到的图像并不是最终摄取成像的图像。为了便于区分这两个摄像头采集到的图像，将该第一摄像头采集到的图像称为第一预览图像，将该第二摄像头采集到的图像称为第二预览图像。Before the image capturing instruction is detected, the first camera and the second camera can capture images, but the images captured at this time are not the final captured and imaged images. In order to distinguish the images captured by the two cameras, the image captured by the first camera is called a first preview image, and the image captured by the second camera is called a second preview image.
103，当检测到图像摄取指令时，将该第一预览图像与该第二预览图像拼接为合成图像。103. When an image capture instruction is detected, stitch the first preview image and the second preview image into a composite image.
与现有的不同，在本申请实施例中检测到图像摄取指令时，将该第一预览图像与该第二预览图像拼接成的合成图像作为最终摄取到的图像。Different from the existing ones, when an image capture instruction is detected in the embodiment of the present application, a composite image formed by splicing the first preview image and the second preview image is used as the finally captured image.
其中，当检测到图像摄取指令时，可以是直接获取采集到的该第一预览图像与该第二预览图像并拼接；也可以是检测到该图像摄取指令后，控制该第一摄像头和第二摄像头同时进行图像摄取，摄取到该第一预览图像和该第二预览图像后，再将该第一预览图像与该第二预览图像进行拼接，得到该合成图像。Wherein, when the image capture instruction is detected, the first preview image and the second preview image collected may be directly acquired and spliced; or after the image capture instruction is detected, the first camera and the second preview image may be controlled. The camera captures images at the same time, and after capturing the first preview image and the second preview image, splicing the first preview image and the second preview image to obtain the synthesized image.
可以理解的是，通过将第一摄像头采集到的第一预览图像与该第二摄像头采集到的第二预览图像进行拼接，可以同时将两处不同景物摄取到同一幅图像中。这样，用户便可以基于该电子设备的一个摄像头摄取用户，另一个摄像头摄取该用户之外的其他待拍摄的目标人物或景物，从而实现用户与其他人或景物合影。It can be understood that by splicing the first preview image captured by the first camera and the second preview image captured by the second camera, two different scenes can be captured into the same image at the same time. In this way, the user can capture the user based on one camera of the electronic device, and the other camera captures other target people or scenes to be photographed besides the user, so that the user can take a group photo with other people or scenes.
如，用户在希望游览景物过程中如果希望在游览地拍照留念，则可以通过本申请的方法同时开启电子设备的两个摄像头，使得一个摄像头正对用户，而另一个摄像头正对待拍摄景物，当该用户触发图像摄取时，则该电子设备会将这两个摄取到的图像进行拼接，从而使得拼接出的图像中包含了该用户与该景物，达到了在该游览地拍照留念的目的。For example, if a user wants to take pictures at a place to take pictures during the process of visiting a scene, the two cameras of the electronic device can be turned on at the same time through the method of this application, so that one camera is facing the user, while the other camera is facing the scene. When the user triggers image capture, the electronic device will stitch the two captured images, so that the stitched image includes the user and the scene, achieving the purpose of taking pictures at the tourist destination.
又如，以手机为例，当用户A与另一用户B在餐厅吃饭时，如果该两个用户相对而坐的情况下，如果用户A希望与用户B进行合影，则可以触发手机同时启动前、后两个摄像头，并通过这两个摄像头分别采集用户A以及用户B的图像，当用户A触发手机摄取图像后，手机将前后摄像头采集到的图像进行拼接，从而生成了用户A与用户B的合影图像。As another example, taking a mobile phone as an example, when user A and another user B are eating in a restaurant, if the two users are sitting opposite each other, if user A wants to take a group photo with user B, the mobile phone can be triggered to start at the same time. , the last two cameras, and collect images of user A and user B through these two cameras. When user A triggers the mobile phone to capture images, the mobile phone will splice the images collected by the front and rear cameras, thereby generating user A and user B. photo image.
本申请实施例中，当检测到预设指令后，控制该第一摄像头和第二摄像头同时处于开启状态，并当检测到图像摄取指令时，将该第一摄像头采集到的第一预览图像与第二摄像头采集到的第二预览图像进行拼接，得到包含有第一预览图像和第二预览图像的合成图像，实现了将处于不同摄像头摄像范围内的两处不同景物同时摄取到一幅图像中，从而使得用户与处于该用户所在的摄像范围之外的人或景物的合影，提高了摄像的灵活性，避免了求助他人来为用户进行拍照，降低了摄像的复杂度。In the embodiment of the present application, when the preset instruction is detected, the first camera and the second camera are controlled to be turned on at the same time, and when the image capture instruction is detected, the first preview image captured by the first camera is combined with the The second preview image collected by the second camera is spliced to obtain a composite image including the first preview image and the second preview image, which realizes the simultaneous capture of two different scenes within the shooting range of different cameras into one image , so that the user takes a photo with a person or scene outside the user's camera range, improves the flexibility of the camera, avoids asking others to take pictures for the user, and reduces the complexity of the camera.
可以理解的是，在本申请实施例中，将该第一预览图像与该第二预览图像拼接为合成图像之前，可以根据需要设定该第一预览图像和该第二预览图像在该需要合成的合成图像的位置，如，可以将该第一预览图像设置在待合成的合成图像的第一展现区域，将该第二预览图像设置在该待合成的合成图像的第二展现区域，并基于该第一展现区域与该第二展现区域的相位位置关系，将该第一预览图像与该第二预览图像进行拼接为该合成图像。可见，在本实施例中，合成图像的第一展现区域对应着该第一摄像头摄取到的图像，而该第二展现区域对应着第二摄像头摄取到图像，从而使得两个摄像头摄取到的图像在该合成图像中的展现位置固定，以便于用户根据需要调整这两个摄像头所需摄取的目标。It can be understood that, in the embodiment of the present application, before the first preview image and the second preview image are spliced into a composite image, the first preview image and the second preview image can be set as required to be composited The location of the synthesized image, for example, the first preview image can be set in the first presentation area of the synthesized image to be synthesized, the second preview image can be set in the second presentation area of the synthesized image to be synthesized, and based on The phase position relationship between the first display area and the second display area, the first preview image and the second preview image are spliced into the composite image. It can be seen that in this embodiment, the first display area of the composite image corresponds to the image captured by the first camera, and the second display area corresponds to the image captured by the second camera, so that the images captured by the two cameras The presentation position in the composite image is fixed, so that the user can adjust the objects to be captured by the two cameras according to needs.
其中，该第一展现区域与该第二展现区域为该合成图像的两个不同区域。如，可以将待合成的合成图像分成左右两个对称区域，左边的区域可以为第一展现区域，右边的区域可以为第二展现区域。该第一预览图像可以正向设置在该第一展现区域，且该第二预览图像可以正向设置在该第二展现区域，该第一展现区域与该第二展现区域的图像进行合并便得到该合成图像。如参见图2a-2c，其中，图2a其示出了第一摄像头摄取到的第一预览图像的示意图；图2a，示出了第二摄像头摄取到的第二预览图像的示意图；图2c示出了由第一预览图像与该第二预览图像拼接成的合成图像的示意图。由图2a-2c可以看出，第一预览图像与该第二预览图像中均包含有一个人物的图像，但这两幅图像的背景却不相同，而通过拼接，使得该合成图像中包含了第一预览图像与第二预览图像中的人物，从而实现了处于不同位置区域的人物之间的合影。Wherein, the first presentation area and the second presentation area are two different areas of the synthesized image. For example, the synthesized image to be synthesized may be divided into left and right symmetrical areas, the left area may be the first presentation area, and the right area may be the second presentation area. The first preview image can be set in the first display area in the forward direction, and the second preview image can be set in the second display area in the forward direction, and the images of the first display area and the second display area can be combined to obtain The composite image. 2a-2c, wherein, FIG. 2a shows a schematic diagram of the first preview image captured by the first camera; FIG. 2a shows a schematic diagram of the second preview image captured by the second camera; FIG. 2c shows A schematic diagram of a composite image formed by splicing the first preview image and the second preview image is shown. It can be seen from Figures 2a-2c that both the first preview image and the second preview image contain an image of a person, but the backgrounds of the two images are different, and through splicing, the composite image contains The people in the first preview image and the second preview image realize group photos between people in different locations.
需要说明的是，该第一展现区域和第二展现区域可以没有重叠，在此情况下，可以直接拼接第一展现区域与该第二展现区域展现出的图像。It should be noted that the first presentation area and the second presentation area may not overlap. In this case, the images displayed in the first presentation area and the second presentation area may be directly spliced.
当然，该第一展现区域和第二展现区域也可以有重叠，且该第一展现区域与该第二展现区域的重叠区域的面积小于该第一展现区域和该第二展现区域中任意一个区域的面积。在此情况下，如果将该第一预览图像设置在该第一展现区域，将该第二预览图像设置在该第二展现区域时，则该第一预览图像与该第二预览图像会存在重叠，则在拼接时，可以裁剪重叠区域中属于该第一预览图像的部分或者是属于该第二预览图像的部分后，再将该第一预览图像与该第二预览图像进行拼接。Of course, the first presentation area and the second presentation area may also overlap, and the area of the overlapping area between the first presentation area and the second presentation area is smaller than any one of the first presentation area and the second presentation area area. In this case, if the first preview image is set in the first display area and the second preview image is set in the second display area, the first preview image and the second preview image will overlap , then during splicing, after the part belonging to the first preview image or the part belonging to the second preview image in the overlapping area can be cropped, the first preview image and the second preview image can be spliced.
可以理解的是，由于该第一预览图像与该第二预览图像分别为两个摄像头摄取到的图像，而这两个摄像头的图像摄取范围之间不存在交集，使得这两幅图像的背景之间差异过大，如果直接将该第一预览图像与该第二预览图像进行拼接，则会使得这两幅图片的拼接处显示过于突兀。为了解决该问题，可选的，在本申请实施例在对该第一预览图像与该第二预览图像进行拼接之前，还可以将预置的连接图片设置在该待合成图像的第三展现区域，然后基于该第一展现区域、第二展现区域与该第三展现区域的相对位置关系，分别将该第一预览图像和该第二预览图像与该连接图片进行拼接，以得到拼接有该第一预览图像、第二预览图像以及连接图片的合成图像。It can be understood that since the first preview image and the second preview image are images captured by two cameras respectively, and there is no intersection between the image capture ranges of the two cameras, the background of the two images If the difference between the two images is too large, if the first preview image and the second preview image are directly spliced, the splicing of the two images will be displayed too abruptly. In order to solve this problem, optionally, in this embodiment of the present application, before splicing the first preview image and the second preview image, a preset connection picture may also be set in the third presentation area of the image to be synthesized , and then based on the relative positional relationship between the first presentation area, the second presentation area, and the third presentation area, the first preview image, the second preview image, and the connected picture are spliced respectively, so as to obtain the spliced first preview image and the second preview image. A composite image of a preview image, a second preview image and the connected pictures.
其中，该第三展现区域与该第一展现区域以及该第二展现区域均不相同，该第三展现区域与该第一展现区域和第二展现区域相邻。该第三展现区域可以为规则图形，也可以是不规则图形。而该第三展现区域与该第一展现区域以及该第二展现区域相邻，但该第三展现区域与该第一展现区域以及第二展现区域相邻有多种情况。Wherein, the third display area is different from the first display area and the second display area, and the third display area is adjacent to the first display area and the second display area. The third display area can be a regular figure or an irregular figure. The third presentation area is adjacent to the first presentation area and the second presentation area, but there are many situations where the third presentation area is adjacent to the first presentation area and the second presentation area.
