背景技术Background technique
随着具有拍摄功能的电子设备的广泛应用，一般的，在拍摄照片或视频过程中可以选择对人脸图像进行自动美颜，即根据美颜参数对人脸图像进行美颜处理。具体的，自动美颜可以根据美学理论(如，平均脸、对称性或黄金分割等)对人脸图像进行调整。但是，依据美学理论对人脸图像进行的普适化的美颜处理，无法满足用户的个性化需求。With the widespread use of electronic devices with shooting functions, generally, during the process of taking photos or videos, you can choose to automatically beautify the face image, that is, perform beautification processing on the face image according to the beautification parameters. Specifically, automatic beautification can adjust the face image according to aesthetic theories (such as average face, symmetry, or golden section, etc.). However, universal beautification processing of facial images based on aesthetic theory cannot meet the personalized needs of users.
在相关技术中，可以通过不同的调整项目，对人脸图像中的部分区域(如，脸型、眼睛或嘴巴等)进行美颜处理。上述调整项目还可以进一步细化，如，将眼睛对应的调整项目拆分成与眼睛大小、眼睛亮度、眼球色彩分别对应的调整项目，以便于对人脸图像进行精细化地美颜处理。用户可以通过用户交互界面对上述调整项目进行逐个调整，以便于得到每个调整项目的调整结果对应的美颜参数，然后采用美颜参数对人脸图像进行美颜处理，得到美颜图像。In related technologies, beautification processing can be performed on some areas in a face image (such as face shape, eyes or mouth, etc.) through different adjustment items. The above-mentioned adjustment items can be further refined. For example, the adjustment items corresponding to the eyes are split into adjustment items corresponding to eye size, eye brightness, and eyeball color, so as to facilitate refined beautification processing of the face image. The user can adjust the above adjustment items one by one through the user interaction interface in order to obtain the beautification parameters corresponding to the adjustment results of each adjustment item, and then use the beautification parameters to perform beautification processing on the face image to obtain a beautification image.
然而，由于上述调整项目的数量可能是几个、十几个、甚至几十个，并且，各个调整项目之间对人脸图像进行美颜处理时相互影响，因此，需要对调整项目逐个调整，并根据美颜效果反复调整。然而，用户并不是专业调试人员，上述美颜参数的获取方式，操作繁琐，耗时较长，并且，采用美颜参数对人脸图像进行美颜处理后的美颜图像，难以达到用户满意的美颜效果。However, since the number of the above adjustment items may be several, a dozen, or even dozens, and each adjustment item affects each other when beautifying the face image, the adjustment items need to be adjusted one by one. And adjust it repeatedly according to the beauty effect. However, the user is not a professional debugger. The above-mentioned method of obtaining the beautification parameters is cumbersome and time-consuming. Moreover, the beautification image processed by using the beautification parameters to beautify the face image is difficult to satisfy the user. Beauty effect.

可选地，在本申请实施例中，电子设备根据默认设置方式或者图像标识，确定素颜人脸图像(如图13所示)和带妆人脸图像(如图17中的(b)所示)，再根据素颜人脸图像和带妆人脸图像的像素差异，得到自定义美颜参数。需要说明的是，获取美颜参数的实现过程，可以由图像处理芯片实现，或者由电子设备(安装具有确定美颜参数功能的应用程序的)中的处理器实现。需要说明的是，如果第一类型图像是素颜人脸图像，则第二类型图像是带妆人脸图像，相反的，如果第一类型图像是带妆人脸图像，则第二类型图像是素颜人脸图像。Optionally, in this embodiment of the present application, the electronic device determines the face image without makeup (as shown in Figure 13) and the face image with makeup (as shown in (b) of Figure 17 ), and then obtain customized beauty parameters based on the pixel difference between the face image without makeup and the face image with makeup. It should be noted that the process of obtaining the beautification parameters can be implemented by an image processing chip, or by a processor in an electronic device (installed with an application program capable of determining the beautification parameters). It should be noted that if the first type of image is a face image without makeup, then the second type image is a face image with makeup. On the contrary, if the first type image is a face image with makeup, then the second type image is a face image with no makeup. Face images.
在本申请实施例中，自定义美颜参数即为颜色查找表(Look-Up-Table，LUT)，也可以称为LUT文件或者LUT参数，是一种红绿蓝(Red Green Blue，RGB)的映射表。具体的，一张图像包括很多像素，每个像素由RGB值表示。电子设备的显示屏可以根据该图像中每个像素点的RGB值来显示该图像。也就是说，这些RGB值会告诉显示屏如何发光，以混合出各种各样的色彩呈现给用户。如果想要改变该图像的色彩(或者风格、效果)，则可以调整这些RGB值即可。LUT是一种RGB的映射表，用于表征调整前后的RGB值的对应关系。例如，请参考表1，其示出一种LUT的示例。In the embodiment of this application, the custom beauty parameter is a color look-up table (Look-Up-Table, LUT), which can also be called a LUT file or LUT parameter. It is a red, green, blue (Red Green Blue, RGB) mapping table. Specifically, an image includes many pixels, each pixel is represented by an RGB value. The display screen of the electronic device can display the image based on the RGB value of each pixel in the image. In other words, these RGB values will tell the display how to emit light to mix a variety of colors for the user. If you want to change the color (or style, effect) of the image, you can adjust these RGB values. LUT is an RGB mapping table, used to represent the corresponding relationship between RGB values before and after adjustment. For example, please refer to Table 1, which shows an example of a LUT.
表1Table 1
当原始RGB值为(14,22,24)时，经过表1所示的LUT的映射，输出RGB值为(6,9,4,)。当原始RGB值为(61,34,67)时，经过表1所示的LUT的映射，输出RGB值为(66,17,47)。当原始RGB值为(94,14,171)时，经过表1所示的LUT的映射，输出RGB值为(117,82,187)。当原始RGB值为(241,216,222)时，经过表1所示的LUT的映射，输出RGB值为(255,247,243)。When the original RGB value is (14,22,24), after mapping by the LUT shown in Table 1, the output RGB value is (6,9,4,). When the original RGB value is (61,34,67), after mapping by the LUT shown in Table 1, the output RGB value is (66,17,47). When the original RGB value is (94,14,171), after mapping by the LUT shown in Table 1, the output RGB value is (117,82,187). When the original RGB value is (241,216,222), after mapping by the LUT shown in Table 1, the output RGB value is (255,247,243).
需要说明的是，针对同一张图像，未采用LUT处理过的图像的显示效果与采用LUT处理过的图像的显示效果不同；采用不同的LUT处理同一张图像，可以得到不同风格的显示效果。本申请实施例中所述的图像的“显示效果”是指图像被显示屏显示后，可以被人眼观察到的图像效果。It should be noted that for the same image, the display effect of the image without LUT processing is different from the display effect of the image processed by LUT; using different LUTs to process the same image can obtain different styles of display effects. The "display effect" of an image described in the embodiments of this application refers to the image effect that can be observed by human eyes after the image is displayed on the display screen.
在本申请实施例中，由于素颜人脸图像和带妆人脸图像所包含的人脸图像高度相似，仅有色彩、亮度等效果维度的差异，因此，可以逐个像素分别提取素颜人脸图像和带妆人脸图像的人脸区域的色彩，建立像素级的映射关系，该映射关系用于表示素颜状态和带妆状态之间的差异，即，等效于自定义美颜参数。In the embodiment of the present application, since the face images contained in the face image without makeup and the face image with makeup are highly similar, with only differences in effect dimensions such as color and brightness, the face image without makeup and the face image with makeup can be extracted pixel by pixel respectively. The color of the face area of the face image with makeup establishes a pixel-level mapping relationship. This mapping relationship is used to represent the difference between the state without makeup and the state with makeup, that is, it is equivalent to a custom beauty parameter.
可选地，在本申请实施例中，电子设备可以首先检测素颜人脸图像或带妆人脸图像的人脸关键点并基于关键点将人脸分割为若干区域，然后分别提取每个区域的色彩信息，最后针对素颜人脸图像和带妆人脸图像相对应的人脸区域，建立像素级的对应关系，生成LUT，以提高得到自定义美颜参数的速度。Optionally, in the embodiment of the present application, the electronic device can first detect the key points of the face in the face image without makeup or the face image with makeup, segment the face into several regions based on the key points, and then extract the facial features of each region respectively. Color information, and finally establish a pixel-level correspondence between the face areas corresponding to the face image without makeup and the face image with makeup, and generate a LUT to increase the speed of obtaining customized beauty parameters.
进一步可选地，在本申请实施例中，依据总体实现思路：首先对第一图像和第二图像进行区域划分，然后比较每一组对应的人脸区域的像素差异，得到自定义美颜参数。如图18所示，本步骤404还可以通过如下步骤1801至步骤1802实现。Further optionally, in the embodiment of the present application, according to the overall implementation idea: first divide the first image and the second image into regions, and then compare the pixel differences of the corresponding face regions in each group to obtain the customized beauty parameters. . As shown in Figure 18, this step 404 can also be implemented through the following steps 1801 to 1802.
步骤1801、电子设备将素颜人脸图像通过预置人脸区域分割算法划分为至少一个第一人脸区域，将带妆人脸图像通过预置人脸区域分割算法划分为至少一个第二人脸区域。Step 1801. The electronic device divides the face image without makeup into at least one first face area through a preset face area segmentation algorithm, and divides the face image with makeup into at least one second face area through a preset face area segmentation algorithm. area.
步骤1802、电子设备根据第一人脸区域的区域类型，第一人脸区域，以及与第一人脸区域对应的第二人脸区域，得到自定义美颜参数。Step 1802: The electronic device obtains customized beauty parameters based on the area type of the first face area, the first face area, and the second face area corresponding to the first face area.
在本申请实施例中，素颜人脸图像为第一类型图像或第二类型图像，相对应的，带妆人脸图像为第二类型图像或第一类型图像。第一人脸区域与第二人脸区域一一对应，区域类型包括色彩均匀区域类型和色彩差异区域类型。可以理解的是，由于素颜人脸图像和带妆人脸图像，都符合人脸框的边界限定，从整体上图像的大小，人脸位置、人脸中的五官位置都较为相似，因此，根据相同的预置人脸区域分割算法划分的第一人脸区域与第二人脸区域时一一对应的。In this embodiment of the present application, the face image without makeup is a first type image or a second type image, and correspondingly, the face image with makeup is a second type image or a first type image. The first face area corresponds to the second face area one-to-one, and the area types include a uniform color area type and a color difference area type. It is understandable that since the face images without makeup and the face images with makeup both comply with the boundary limits of the face frame, the overall size of the image, the position of the face, and the position of the facial features in the face are relatively similar. Therefore, according to The first face area and the second face area divided by the same preset face area segmentation algorithm are in one-to-one correspondence.
进一步可选地，在本申请实施例中，上述步骤1801中的将素颜人脸图像通过预置人脸区域分割算法划分为至少一个第一人脸区域，具体实现方式为：根据预置样本，训练主动形状模型(Active Shape Model，ASM)，其中，预置样本为具有脸部特征点标识的人脸图像；将素颜人脸图像输入训练好的ASM，获取素颜人脸图像的第一搜索特征点；根据第一搜索特征点，构建人脸区域的形状向量，得到至少一个第一人脸区域。Further optionally, in this embodiment of the present application, in the above step 1801, the plain face image is divided into at least one first face area through a preset face area segmentation algorithm. The specific implementation method is: according to the preset sample, Train the Active Shape Model (ASM), in which the preset samples are face images with facial feature point identifiers; input the plain face image into the trained ASM to obtain the first search feature of the plain face image points; construct a shape vector of the face area according to the first search feature point, and obtain at least one first face area.
在本申请实施例中，ASM是基于特征点分布模型(Point Distribution Model，PDM)提取形状的方法，在PDM中，外形相似的物体，如，人脸、手、心脏、肺部等几何形状，可以通过若干关键特征点的坐标依次串联形成一个形状向量。在ASM训练过程中，收集训练样本、标记人脸部特征点，构建形状向量、再对所有人脸图像进行归一化和对齐，为每个特征点构建局部特征，以此实现对ASM的训练。在完成训练后，即可根据训练好的ASM在素颜人脸图像的人脸中搜索特征点，得到人脸特征点的区域分割结果。如此，通过ASM得到的第一搜索特征点，构建人脸区域得到的第一人脸区域，与人脸五官的外轮廓相似度较高，与实际的化妆区域相对应，能够提高判断第一人脸区域对应的区域类型的准确度，进而提高用于对于自定义美颜参数的满意度。In the embodiment of this application, ASM is a method of extracting shapes based on the feature point distribution model (PDM). In PDM, objects with similar appearances, such as faces, hands, hearts, lungs and other geometric shapes, A shape vector can be formed by concatenating the coordinates of several key feature points in sequence. During the ASM training process, training samples are collected, facial feature points are marked, shape vectors are constructed, all face images are normalized and aligned, and local features are constructed for each feature point to achieve ASM training. . After completing the training, the trained ASM can be used to search for feature points in the face of the plain face image, and obtain the regional segmentation results of the face feature points. In this way, the first search feature point obtained by ASM and the first face area obtained by constructing the face area have a high similarity with the outer contour of the facial features and correspond to the actual makeup area, which can improve the judgment of the first person. The accuracy of the area type corresponding to the face area, thereby improving the degree of satisfaction with custom beauty parameters.
可以理解的是，与上述对素颜人脸图像的划分过程类似，上述步骤1801中的将带妆人脸图像通过预置人脸区域分割算法划分为至少一个第二人脸区域，具体包括：根据预置样本，训练ASM，其中，预置样本为具有脸部特征点标识的人脸图像；将带妆人脸图像输入训练好的ASM，获取带妆人脸图像的第一搜索特征点；根据第一搜索特征点，构建人脸区域的形状向量，得到至少一个第一人脸区域。对于带妆人脸图像对应的第二人脸区域的划分过程，在此不再赘述。It can be understood that, similar to the above-mentioned dividing process of the face image without makeup, the face image with makeup in step 1801 is divided into at least one second face area through the preset face area segmentation algorithm, specifically including: according to Preset samples to train ASM, where the preset samples are face images with facial feature point identifiers; input the face image with makeup into the trained ASM to obtain the first search feature point of the face image with makeup; according to First search for feature points, construct a shape vector of the face area, and obtain at least one first face area. The process of dividing the second face area corresponding to the face image with makeup will not be described again here.
需要说明的是，在本申请实施例中，对于人脸区域的划分方式还可以采取其他划分方法，在此不做限定。It should be noted that in the embodiment of the present application, other division methods can also be adopted for dividing the face area, which are not limited here.
如此，根据化妆效果特征，对第一人脸区域进行分类(区域类型包括色彩均匀区域类型和色彩差异区域类型)，再根据不同的区域类型建立素颜人脸图像和带妆人脸图像之间的色彩映射关系，能够提高自定义美颜参数的获取效率。In this way, the first face area is classified according to the characteristics of the makeup effect (area types include uniform color area type and color difference area type), and then the relationship between the face image without makeup and the face image with makeup is established based on different area types. The color mapping relationship can improve the efficiency of obtaining customized beauty parameters.
进一步可选地，在本申请实施例中，在得到自定义美颜参数之前，电子设备还可以判断至少一个第一人脸区域中的每个第一人脸区域的区域类型。具体的，电子设备可以将图像特征中偏均匀和平滑的第一人脸区域的区域类型判断为色彩均匀区域类型。区域类型的判断方法具体包括：获取第一人脸区域的区域内像素的第一色彩分量均值，以及素颜人脸图像的图像内像素的第二色彩分量均值，其中，第一色彩分量均值包括：第一R分量平均值、第一G分量平均值和第一B分量平均值，第二色彩分量均值包括：第二R分量平均值、第二G分量平均值和第二B分量平均值；将第一色彩分量均值与第二色彩分量均值进行比较；在第一色彩分量均值与第二色彩分量均值之间的平均差异小于第三预置阈值的情况下，确定第一人脸区域的区域类型为色彩均匀类型；在第一色彩分量均值与第二色彩分量均值之间的平均差异大于或等于第三预置阈值的情况下，确定第一人脸区域的区域类型为色彩差异类型。Further optionally, in this embodiment of the present application, before obtaining the customized beautification parameters, the electronic device may also determine the area type of each first face area in the at least one first face area. Specifically, the electronic device may determine the area type of the first face area that is relatively uniform and smooth in the image features as a uniform color area type. The method for determining the area type specifically includes: obtaining the first color component mean value of the pixels in the first face area, and the second color component mean value of the pixels in the image of the plain face image, where the first color component mean value includes: The first R component average value, the first G component average value and the first B component average value, the second color component average value includes: the second R component average value, the second G component average value and the second B component average value; Compare the first color component mean value with the second color component mean value; when the average difference between the first color component mean value and the second color component mean value is less than the third preset threshold, determine the area type of the first face area It is a color uniform type; when the average difference between the first color component mean value and the second color component mean value is greater than or equal to the third preset threshold, the area type of the first face area is determined to be the color difference type.
可以理解的是，色彩均匀类型对应的人脸区域是均匀平坦的，色彩差异类型对应的人脸区域是细节纹理丰富的。示例性的，上述第三预置阈值可以设置为10％。It can be understood that the face area corresponding to the uniform color type is uniform and flat, and the face area corresponding to the color difference type is rich in detail and texture. For example, the above third preset threshold may be set to 10%.
如此，由于“色彩”是素颜人脸图像与带妆人脸图像的主要区别，因此，根据色彩分量均值判断第一人脸区域的区域类型，使得同一区域类型的像素分布特点类似，能够提高针对不同区域类型采用不同映射方式的准确度，进行提高得到自定义美颜参数的速度。In this way, since "color" is the main difference between a face image without makeup and a face image with makeup, the area type of the first face area is determined based on the mean value of the color components, so that the pixel distribution characteristics of the same area type are similar, which can improve the target Different area types use different mapping methods to improve the accuracy of obtaining customized beauty parameters.
在一种示例中，在第一人脸区域的区域类型为色彩均匀类型的情况下，电子设备根据第一人脸区域，以及与第一人脸区域对应的第二人脸区域，采用逐个像素点映射的方式，建立第一人脸区域和第二人脸区域的映射关系；在第一人脸区域的区域类型为色彩差异类型的情况下，电子设备根据第一人脸区域，以及与第一人脸区域对应的第二人脸区域，采用区域平均像素整体映射的方式，建立第一人脸区域和第二人脸区域的映射关系；电子设备将映射关系中的参数确定为自定义美颜参数。In one example, when the area type of the first face area is a uniform color type, the electronic device uses a pixel-by-pixel method based on the first face area and the second face area corresponding to the first face area. Point mapping is used to establish a mapping relationship between the first face area and the second face area; when the area type of the first face area is a color difference type, the electronic device determines the relationship between the first face area and the second face area based on the color difference type. The second face area corresponding to one face area uses a regional average pixel overall mapping method to establish a mapping relationship between the first face area and the second face area; the electronic device determines the parameters in the mapping relationship as custom beauty Color parameters.
在另一种示例中，在第一人脸区域的区域类型为色彩差异类型的情况下，以第一人脸区域中的第一像素点为起点，电子设备按照预置区域大小将第一人脸区域划分为至少一个第一矩形区域，并获取至少一个第一矩形区域中的每个第一矩形区域的像素平均值；以第二人脸区域中的第二像素点为起点，电子设备按照预置区域大小将第二人脸区域划分为至少一个第二矩形区域，并获取至少一个第二矩形区域中的每个第二矩形区域的像素平均值，第一像素点与第二像素点相对应；电子设备建立第一矩形区域的像素平均值，与第二矩形区域的像素平均值的映射关系。示例性的，预置区域大小可以设置为包含10000个像素点。In another example, when the area type of the first face area is the color difference type, taking the first pixel in the first face area as the starting point, the electronic device divides the first person into the first face area according to the preset area size. Divide the face area into at least one first rectangular area, and obtain the pixel average value of each first rectangular area in the at least one first rectangular area; taking the second pixel point in the second face area as a starting point, the electronic device follows The preset area size divides the second face area into at least one second rectangular area, and obtains the pixel average value of each second rectangular area in the at least one second rectangular area, and the first pixel point is relative to the second pixel point. Correspondingly: the electronic device establishes a mapping relationship between the average pixel value of the first rectangular area and the average pixel value of the second rectangular area. For example, the preset area size can be set to include 10,000 pixels.
需要说明的是，在上述示例中的映射关系是通过LUT实现的。在图像处理方面，LUT可以用来完成类似滤镜的效果，其原理是一种映射关系，输入颜色(r，g，b)，通过LUT查找等到一个新的颜色(R，G，B)，则完成了一次映射操作。LUT本质上属于独立像素点替换，让每个像素点都会对应一个新的颜色值。It should be noted that the mapping relationship in the above example is implemented through LUT. In terms of image processing, LUT can be used to achieve filter-like effects. The principle is a mapping relationship. Input a color (r, g, b), and wait until a new color (R, G, B) is found through the LUT. A mapping operation is completed. LUT is essentially an independent pixel replacement, so that each pixel corresponds to a new color value.
可以理解的是，由于素颜人脸图像和带妆人脸图像中的人脸图像内容高度相似，仅有色彩、亮度等效果维度的差异，因此，逐个像素分别提取第一人脸区域，以及与第一人脸区域对应的第二人脸区域的色彩，建立像素级映射关系，即，同一人脸的素颜状态和带妆状态之间的差异，等同于用户自定义的美颜参数。It can be understood that since the content of the face image in the face image without makeup and the face image with makeup are highly similar, with only differences in effect dimensions such as color and brightness, the first face area is extracted pixel by pixel, and the first face area is extracted pixel by pixel. The color of the second face area corresponding to the first face area establishes a pixel-level mapping relationship, that is, the difference between the bare makeup state and the makeup state of the same face is equivalent to the user-defined beauty parameters.
示例性的，选取至少一个第一人脸区域中包含眼部区域的目标第一人脸区域，以及与目标第一人脸区域对应的目标第二人脸区域，提取目标第一人脸区域中目标像素点的像素值(r，g，b)作为原始值1，并提取与该目标像素点对应的目标第二人脸区域中相对像素点的像素值(R，G，B)作为输出值1，以此类推，获取眼部区域完整的原始值和输出值，将全部信息存贮为表示颜色映射关系的LUT，该LUT即是用户的自定义眼部区域美颜参数。当摄像头捕捉到的人脸图像中包括眼部区域时，将LUT应用在当前捕捉到的人脸图像的眼部区域，根据查找表的对应关系建立映射，达到美化后的眼部区域效果。Exemplarily, select at least one target first face area including the eye area in the first face area, and a target second face area corresponding to the target first face area, and extract the target first face area The pixel value (r, g, b) of the target pixel point is used as the original value 1, and the pixel value (R, G, B) of the relative pixel point in the target second face area corresponding to the target pixel point is extracted as the output value 1. By analogy, obtain the complete original value and output value of the eye area, and store all the information as a LUT representing the color mapping relationship. This LUT is the user's customized eye area beauty parameter. When the face image captured by the camera includes the eye area, the LUT is applied to the eye area of the currently captured face image, and mapping is established based on the corresponding relationship in the lookup table to achieve a beautified eye area effect.

示例性的，通过拖动操作或点击操作，更改如图22所示的美颜程度控制条的标记位置，能够改变美颜处理力度。以嘴唇颜色为例，素颜人脸图像中嘴唇颜色为浅粉色，经过带妆人脸图像中嘴唇颜色为大红色，即采集的第一图像中嘴唇颜色为浅粉色，而第二图像中的嘴唇颜色为大红色。由于大红色的色彩比较突出，可能与第二图像中的头发颜色不匹配，可以接收用户对美颜程度控制条的调整操作，将标记位置调整至中间位置，即，将美颜程度控制条对应的美颜处理的力度为50％。假设第一图像中嘴唇对应的像素点的RGB为(255,192,203)，第二图像中嘴唇对应的像素点的RGB为(255,0,0)，那么第三图像中嘴唇对应的像素点的RGB为(255,96,101)。For example, by changing the mark position of the beautification degree control bar as shown in Figure 22 through a drag operation or a click operation, the intensity of the beautification processing can be changed. Take the color of lips as an example. In the face image without makeup, the color of the lips is light pink. In the image of the face with makeup, the color of the lips is bright red. That is, the color of the lips in the first image collected is light pink, and the color of the lips in the second image is light pink. The color is bright red. Since the bright red color is more prominent and may not match the hair color in the second image, you can accept the user's adjustment operation on the beauty degree control bar and adjust the mark position to the middle position, that is, adjust the beauty degree control bar to the corresponding The strength of the beauty treatment is 50%. Assume that the RGB of the pixels corresponding to the lips in the first image is (255,192,203), and the RGB of the pixels corresponding to the lips in the second image is (255,0,0), then the RGB of the pixels corresponding to the lips in the third image is (255,96,101).
如此，通过对美颜程度控制条的调整操作，调整自定义美颜参数的实施力度，以提高编辑后的第三图像符合多样化编辑需求的概率。In this way, by adjusting the beautification degree control bar, the implementation intensity of the customized beautification parameters is adjusted to increase the probability that the edited third image meets diverse editing needs.
在一种示例中，如果第二图像为在拍摄的预览界面显示的图像，那么在图像编辑界面响应于用户的操作，显示第三图像之后，电子设备可以在拍摄的预览界面显示第三图像，或者得到第三图像。In one example, if the second image is an image displayed on the photographed preview interface, then after the image editing interface displays the third image in response to the user's operation, the electronic device may display the third image on the photographed preview interface, Or get a third image.
在另一种示例中，如果第二图像为已得到图像，那么在图像编辑界面响应于用户的操作，显示第三图像之后，电子设备可以得到第三图像。In another example, if the second image is an obtained image, the electronic device may obtain the third image after the image editing interface displays the third image in response to the user's operation.
如此，通过图像编辑界面中的编辑效果控件，能够对第二图像进行再处理，以满足用户对图像效果的多样化编辑需求。In this way, through the editing effect control in the image editing interface, the second image can be reprocessed to meet the user's diverse editing needs for image effects.
