Description

Method, device, electronic equipment and medium for acquiring beauty parameters

Technical Field

The present application relates to the field of image processing technologies, and in particular, to a method, an apparatus, an electronic device, and a medium for obtaining a beauty parameter.

Background

With the wide application of electronic devices with shooting functions, in general, automatic face beautifying can be selected in the process of shooting photos or videos, that is, face beautifying processing can be performed on face images according to beautifying parameters. In particular, automatic facial beautification may be based on aesthetic theory (e.g., average face, symmetry, golden section, etc.) to adjust the facial image. However, the universal beautifying treatment on the face image according to the aesthetic theory cannot meet the personalized requirements of the user.

In the related art, the beauty treatment may be performed on a partial region (e.g., face shape, eyes, mouth, etc.) in the face image through different adjustment items. The above adjustment items may be further refined, for example, the adjustment items corresponding to the eyes may be split into adjustment items corresponding to the eye size, the eye brightness, and the eyeball color, so as to perform fine face-beautifying processing on the face image. The user can adjust the adjustment items one by one through the user interaction interface so as to obtain the beauty parameters corresponding to the adjustment results of each adjustment item, and then the face image is subjected to beauty treatment by adopting the beauty parameters to obtain the beauty image.

However, since the number of the above-mentioned adjustment items may be several, ten or more, or even several tens, and the face images are subjected to the face beautifying process between the respective adjustment items, it is necessary to adjust the adjustment items one by one and repeatedly adjust according to the face beautifying effect. However, the user is not a professional debugger, the above-mentioned method for obtaining the beauty parameters is cumbersome to operate and takes a long time, and the beauty parameters are adopted to make the face image be the beauty image after the face image is subjected to the beauty treatment, so that the user's satisfied beauty effect is difficult to achieve.

Disclosure of Invention

The embodiment of the application provides a method, a device, electronic equipment and a medium for acquiring beauty parameters, which are used for solving the problems that the operation of a mode for acquiring the beauty parameters is complicated, the time consumption is long, and the beauty effect satisfied by a user is difficult to achieve by adopting the beauty parameters to perform the beauty treatment on the beauty images of face images.

In order to achieve the above purpose, the embodiment of the present application adopts the following technical scheme:

in a first aspect, a method for obtaining a beauty parameter is provided, the method comprising: the customized beauty parameters are acquired by receiving and responding to the first operation of the user. Secondly, the user is prompted to take the first type image, the user is guided to input a second operation, and the first type image is acquired in response to the second operation of the user. Again, the user is prompted to take a second type of image, guided to input a third operation, and the second type of image is acquired in response to the third operation of the user. Finally, the user can obtain the custom beauty parameters according to the first image and the second image without inputting other operations by the user. Wherein the second type image and the first type image comprise the same face image, and the second type image and the first type image are different.

In one implementation, a first operation is received at a preview interface of a shot, where the first operation may be a two-finger up-slide operation, so as to quickly trigger to acquire a custom beauty parameter.

In another implementation, the user-defined beauty parameters are obtained through triggering through the preset triggering path and through multiple interactions of the user with the interface.

In the present application, prompting the user to take the first type of image and prompting the user to take the second type of image may adopt at least one prompting mode of: displaying text prompt information, displaying image prompt information and playing sound prompt information. For example, "please shoot a plain face image", play "how to aim the face at the face frame" animation, play "please draw a satisfactory make-up" audio for oneself, play a cue tone.

It should be understood that, in the shot preview interface, the text prompt information or the image prompt information may be displayed on the upper layer, and the preview image may be displayed on the lower layer. If the text or image cues partially overlap the preview image, the transparency of the text or image cues may be increased so that the user can see the complete preview image.

In the application, the first type image and the second type image can be stored in the cache, and after the custom beautifying parameters are obtained, the first type image and the second type image are temporarily reserved or deleted according to the use condition of the cache.

Thus, the user-defined beautifying parameters are obtained by sequentially responding to the first operation, the second operation and the third operation, repeated debugging of the beautifying parameters according to the beautifying effect is not needed, and the operation steps are simple and the time consumption is short. The face image with make-up can be understood as the face effect expected to be achieved by the user, so that the face image which is photographed daily can achieve the face effect satisfied by the user by adopting the face image which is obtained after the face treatment is carried out by adopting the custom face parameters.

In another possible design manner of the first aspect, the user-defined beauty parameters are applied in the beauty treatment process, and the first image may be collected, and the second image may be obtained by processing the first image according to the user-defined beauty parameters.

It should be understood that after the camera acquires the first image, a second image is obtained in response to an image acquisition operation of the user on the first image, where the second image is an image obtained by processing the first image according to the custom beauty parameters.

In this way, the first image acquired is subjected to the beautifying processing in the process of obtaining the second image, namely the first image is processed according to the user-defined beautifying parameters, so that the speed of displaying the first image in response to the user operation is improved.

In another possible design manner of the first aspect, the custom beauty Yan Canshu is applied in the beauty treatment process, and before the second image is obtained by processing the first image according to the custom beauty parameter, the second image may be displayed on the photographed preview interface.

Therefore, the second image is displayed through the shot preview interface, namely, the second image obtained by processing the first image according to the user-defined beautifying parameters is displayed, and the user can observe the beautifying effect image (the second image) through the preview interface in real time, so that the shooting speed of the user is improved, and further, the system resources are saved.

In another possible design manner of the first aspect, the custom beauty Yan Canshu is applied in a beauty treatment process, before the first image is processed according to the custom beauty parameter to obtain the second image, the first image may be displayed on a shot preview interface, the shot preview interface includes a custom beauty application control, and then the second image is displayed on the shot preview interface in response to a fourth operation of the user on the custom beauty application control, where the fourth operation is used to trigger to start a beauty effect.

In this way, the second image is displayed on the shooting preview interface in response to the fourth operation of the user on the custom beauty application control, so that the user can select to display the first image without beauty according to the instant requirement, or display the second image after the first image is processed according to the custom beauty parameter, so as to meet the diversified requirement of the user on the shot preview interface display. The user can observe the beauty effect image (second image) through the preview interface in real time so as to improve the shooting speed of the user and further save system resources.

In another possible design manner of the first aspect, for the second image, in a case of displaying the second image, a beautifying prompt message is sent to prompt the second image to be an image obtained by processing the first image according to the custom beautifying parameter.

It should be understood that the beauty prompt information may be text information, graphic information or sound information, and is sent by using a display screen or a sound tube as a carrier, for example, the beauty prompt information is displayed or played.

Therefore, by sending out the beautifying prompt information, the second image is prompted to be the beautifying image after the beautifying treatment so as to facilitate the user to determine whether to reprocess the second image.

In another possible design of the first aspect, after displaying the second image, a fifth operation input by the user on the second image may also be received, and an image editing interface may be displayed in response to the fifth operation. Wherein the image editing interface includes one or more controls for editing the second image.

In the present application, one or more controls may be used to adjust the hue, environmental enhancement, blurring, rotation, cropping, shooting parameters, filters, matting, graffiti, adding mosaics, adding special effects and text, etc. of the second image.

In this way, the second image can be reprocessed through one or more controls in the image editing interface so as to meet the diversified editing requirements of the user on the image effect.

In another possible design manner of the first aspect, the one or more controls include a beauty degree control bar, where the beauty degree control bar is used to adjust a strength of the second image with custom beauty Yan Canshu. On the basis, a third image is received and displayed in response to the user's adjustment operation of the beauty degree control bar. The third image is an image obtained by processing the second image according to the strength of the beauty treatment corresponding to the adjusted beauty degree control bar and the custom beauty parameters.

Therefore, the implementation strength of the custom beauty parameters is adjusted through the adjustment operation of the beauty degree control bar, so that the probability that the edited third image meets the diversified editing requirements is improved.

In another possible design manner of the first aspect, after prompting the user to capture the second type of image, receiving a third operation of the user, and in response to the third operation of the user, capturing the second type of image if the capturing trigger condition is satisfied. Wherein the shooting trigger condition includes at least one of: the background similarity of the second type image compared with the first type image is larger than a first preset threshold value, the ambient light similarity of the second type image compared with the first type image is larger than a second preset threshold value, and the shooting parameters of the second type image compared with the first type image are the same.

Therefore, the acquisition environment of the second type of image is limited by shooting triggering conditions, the influence of the acquisition environment on the display effect of the second type of image is weakened, the difference between the first type of image and the second type of image is only the cosmetic effect, the probability of obtaining the image after the user-defined beautifying parameters are adopted for carrying out the beautifying treatment is improved, and the user satisfaction effect can be achieved.

In another possible design of the first aspect, an effect selection interface may also be displayed before receiving the first operation of the user. The effect selection interface includes a custom beauty Yan Kongjian, and the first operation is a click operation of the custom beauty Yan Kongjian by the user.

Therefore, the electronic equipment can receive the first operation of the user aiming at the user-defined beauty Yan Kongjian in the effect selection interface, trigger and start the guiding flow for acquiring the beauty parameters, and improve the probability that the user-defined beauty parameters meet the user requirements, so that the speed for acquiring the user-defined beauty parameters is improved.

In another possible design manner of the first aspect, in the case that the first type image is a plain face image, the corresponding second type image is a makeup-carrying face image including the same face image as the first type image; or, in the case that the first type image is a face image with make-up, the corresponding second type image is a plain face image including the same face image as the first type image.

Therefore, according to the self-defined beautifying parameters obtained by the first type image and the second type image, the change from the plain face image to the face image with makeup can be represented, so that the image processed according to the self-defined beautifying parameters has the beautifying effect with makeup.

In another possible design manner of the first aspect, the custom beauty Yan Canshu is obtained according to the first type image and the second type image, firstly, the first type image and the second type image are divided into areas, and then, the pixel differences of the face areas corresponding to each group are compared to obtain the custom beauty parameters. The method specifically comprises the following steps: dividing plain face images in the first type image and the second type image into at least one first face area through a preset face area segmentation algorithm, and dividing makeup-carrying face images in the first type image and the second type image into at least one second face area through a preset face area segmentation algorithm; and comparing the pixel difference between the first face region and the second face region corresponding to the first face region according to the region type of the first face region to obtain the custom face-beautifying parameters, wherein the region type comprises a uniform color region type and a color difference region type.

Therefore, the first face region is classified according to the cosmetic effect characteristics (the region types comprise uniform color region types and different color region types), and then the color mapping relation between the plain face image and the face image with the cosmetic is established according to different region types, so that the efficiency of acquiring the self-defined cosmetic parameters can be improved.

Finally, the custom beauty parameters are obtained according to the effect differences, wherein the program for implementing the effect difference analysis mode and the custom beauty parameters can be stored in the internal memory 221. After the user-defined beautifying parameters are obtained, the user-defined beautifying parameters can be adopted to carry out the beautifying treatment on the face image, so that the beautifying image after the beautifying treatment can achieve the satisfactory beautifying effect of the user.

The method for acquiring the beauty parameters provided by the embodiment of the disclosure is described below with reference to the accompanying drawings. Specifically, referring to fig. 4, one of the flow diagrams of the method for acquiring the beauty parameters provided by the present application is shown, and the method may be applied to an electronic device. As shown in fig. 4, the method includes:

step 401, the electronic device receives a first operation of a user.

The first operation is used for triggering and acquiring the customized beautifying parameters. In the embodiment of the application, the first operation may be a key triggering operation (for example, a volume enlarging key and a volume reducing key are pressed for a long time) input through a mechanical key, a preset operation or a screen triggering operation of a preset gesture input through a touch screen, an image recognition triggering operation of a specific image acquired through a camera, a voice triggering operation of preset voice received through an audio module, or a wireless triggering operation sent by other electronic devices.

In some embodiments, the electronic device may receive the first operation at a photographed preview interface. For example, the first operation may be a two-finger up operation by the user on the photographed preview interface shown in fig. 5.

In other embodiments, the electronic device can display an effect selection interface that includes custom beauty controls. The first operation may be a click operation of custom beauty Yan Kongjian by the user. The effect selection interface is displayed in response to the continuously input user operation through a preset path.

For example, the electronic apparatus displays a plurality of shooting parameter setting interfaces shown in fig. 6 (b) in response to a click operation by the user on more controls in the preview interface of shooting shown in fig. 6 (a). Then, the electronic device displays an effect selection interface shown in fig. 6 (c) in response to a click operation of the beauty effect control in the photographing parameter setting interface by the user. Finally, the electronic device may receive a first operation for custom beauty Yan Kongjian in the effects selection interface.

In one example, if the custom beauty parameter does not exist, the electronic device sets the custom beauty control to an on state in response to a click operation of a status switch shown in (c) in fig. 6 on the right side of custom beauty Yan Kongjian by a user, that is, receives a first operation for custom beauty Yan Kongjian at the effect selection interface, and triggers acquisition of the custom beauty parameter.

In another example, if the custom beauty parameter exists, the electronic device sets the custom beauty control to an on state in response to a click operation of a status switch on the right side of custom beauty Yan Kongjian by a user (as shown in (a) of fig. 7), and displays a drop-down menu of the custom beauty control, where the drop-down menu includes a beauty effect collection control and at least one custom beauty effect control. If the switch on the right side of custom beauty Yan Kongjian in the effect selection interface is in an on state, a drop-down menu of custom beauty control is displayed in response to a click operation (shown in (b) of fig. 7) by the user on the "> >" identifier.

As shown in fig. 8 (a), the electronic device may display a drop-down menu of the custom beauty control on the effect selection interface, and divide the effect selection interface into a first display area and a second display area. Specifically, the electronic device sets an area corresponding to the custom beauty Yan Kongjian as a first display area, sets an area corresponding to a pull-down menu of the custom beauty control as a second display area, and sets different fonts, font sizes, colors and shading for the control and the icon in the first display area and the second display area to perform differential display, for example, reduces the transparency of the first display area, sets the shading of the first display area as gray, and sets the first display area as a non-operation area.

As shown in fig. 8 (b), after receiving an operation of displaying a drop-down menu of the custom beauty control, the electronic device opens the custom beauty effect interface and displays the drop-down menu of the custom beauty control. The user-defined beautifying effect interface and the effect selection interface are different interfaces.

It should be noted that, the electronic device receives the first operation of the user input on the beauty effect acquisition control in the effect selection interface, that is, triggers to acquire the custom beauty parameters in a multistage control manner, so that the probability that the acquired custom beauty parameters meet the user requirements can be improved, and the speed of acquiring the custom beauty parameters is further improved.

In the embodiment of the present application, the effect selection interface may further include a default beauty Yan Kongjian, as shown in (a) in fig. 9, and the effect selection interface includes a default beauty control and a custom beauty Yan Kongjian. The default beauty control and the custom beauty Yan Kongjian cannot be in an on state at the same time.

In one example, as shown in (b) of fig. 9, if there is a unique default beautifying effect and the beautifying parameters cannot be modified, the electronic device sets the default beautifying control to an on state in response to a click operation of a status switch on the right side of the default beautifying Yan Kongjian by a user, that is, the image displayed on the photographed preview interface is subjected to the beautifying processing according to the beautifying parameters corresponding to the default beautifying effect.

In another example, as shown in (b) of fig. 9, if there are at least two default beauty effects, or/and a beauty parameter can be modified, the electronic device sets the default beauty control to an on state in response to a click operation of a status switch on the right side of the default beauty Yan Kongjian by the user, and displays a drop-down menu of the default beauty control. As shown in (c) of fig. 9, if the switch on the right side of default beauty Yan Kongjian is in an on state, the electronic device may display a drop-down menu of custom beauty control in response to a click operation by the user for the "> >" identifier.

It should be noted that, the drop-down menu of the default beauty control may include a default beauty effect, a personalized beauty effect, and a personalized setting. The default beautifying effect can be girl make-up effect, student make-up effect, banquet make-up effect and the like. The personalized beauty effect is to acquire personalized beauty parameters through the adjustment degree of the custom beauty adjustment items, and present the personalized beauty effect.

As shown in (a) in fig. 10, the electronic device may display a drop-down menu of a default beautifying control on the effect selection interface, divide the effect selection interface into a first display area and a second display area, specifically, the electronic device may set an area corresponding to the default beautifying control and the custom beauty Yan Kongjian as the first display area, set a display area corresponding to the drop-down menu of the default beautifying control as the second display area, and set different fonts, font sizes, colors and shading for distinguishing display by using the controls and icons in the first display area and the second display area. For example, the transparency of the first display area is reduced, the ground tint of the first display area is set to gray, and the first display area is set to a non-operation area.

As shown in fig. 10 (b), after receiving an operation of displaying a drop-down menu of the default beauty control, the electronic device may further open a default beauty effect interface to display the drop-down menu of the default beauty control. The default beautifying effect interface and the effect selection interface are different interfaces.

Therefore, the default beautifying control and the custom beautifying Yan Kongjian are displayed on the effect selection interface, two modes for acquiring the beautifying parameters are provided for the user, the diversity of the beautifying effect can be realized, and the possibility that the beautifying effect can meet the actual needs of the user is improved.

Step 402, the electronic device prompts a user to shoot a first type image in response to a first operation, and acquires the first type image in response to a second operation of the user.

In the embodiment of the application, the electronic equipment can respond to the first operation to display a shot preview interface. The electronic device may display a prompt message prompting the user to capture the first type of image on the captured preview interface. And the electronic equipment can display the preview image acquired by the camera on the shot preview interface.

The first type of image can be a plain face image or a face image with makeup.

In some embodiments, the prompting manner for prompting the user to take the first type of image may be: displaying text prompt information and/or displaying image prompt information. The image prompt information may be a static display image or a dynamic playing image (e.g., animation, video). For example, the text prompt may be please capture a plain face image, and the image prompt may be an animation of how to aim the face at the face frame. The text prompt information and the image prompt information displayed in a static state and/or the image prompt information displayed in a loop or single play and dynamic play can be displayed after the first operation is responded and before the second operation is responded.

In other embodiments, the prompting manner for prompting the user to take the first type of image may be: and playing the voice prompt information. Specifically, the electronic device may play the prompt voice information through the sound tube, and the voice prompt information may be a prompt tone or a prompt voice. For example, the voice prompt message may be a voice of "please draw a satisfactory makeup for oneself". The electronic device may set a loop play or a single play of the voice prompt.

It should be understood that the electronic device may set up to display text prompt information or display image prompt information on the upper layer and may also set up to display a preview image on the lower layer on the preview interface of the shooting. If the text or image cues partially overlap the preview image, the electronic device may alter the transparency of the text or image cues to enable the user to see the complete preview image.

In the application, aiming at the prompt information for prompting the user to shoot the first type image, the electronic equipment can respond to the operation of the user and does not prompt any more, or does not prompt any more under the condition that the prompt time exceeds the preset time, or does not prompt any more after receiving the second operation of the user.

Taking the first type of image as a face image of a plain face as an example, as shown in (a) of fig. 11, the electronic device displays text prompt information on a shot preview interface: please shoot a face image of the plain face. The prompt information can be displayed by a message prompt box, bubbles, labels and the like. For the display mode of the message prompt box, the prompt information can be statically displayed in the message prompt box at the preset position, can be scrolled and displayed in the message prompt box at the preset position, can be statically displayed in the message prompt box which is displayed according to the preset movement rule, and can be scrolled and displayed in the message prompt box which is displayed according to the preset movement rule.

For example, as shown in (b) in fig. 11, the electronic device may further display a face frame on the preview interface of the photographing, and display a prompt message of "place face in face frame". The boundary of the face frame is the outline of a face image (front face image), and the user is prompted to acquire the front face image so as to improve the probability of meeting the user requirements of the face image obtained after the face processing is carried out by adopting the custom face parameter. It will be appreciated that the boundaries of the above-described face box are universal blur contours that can fit all users' face images.

Optionally, in the embodiment of the present application, since the first type image may be a plain face image or a face image with makeup, the electronic device may set a face makeup attribute of the first type image to be a plain face image, may set a face makeup attribute of the first type image to be a face image with makeup, and may set a detection result of the face makeup attribute of the first type image to be a face image with makeup, where the detection result of the face makeup attribute is a plain face image or a face image with makeup.

It can be understood that the electronic device detects the facial makeup attribute of the first type of image, specifically, can detect the color of the skin around the eyes, the smoothness of the skin or the contour of the eyebrows through an image recognition algorithm, and detects whether the facial makeup attribute is a plain facial image or a makeup facial image. Thereafter, the electronic device marks the first image with the detection result as a tag. The detection result of the face dressing attribute can be identified by a preset code, a preset identifier or a preset file name, and the preset code can be 00, 01 or 88, the preset identifier can be triangle, circle or exclamation mark, the preset file name can be a single character with the first bit of the file name set as fixed, a plurality of characters with the first few bits of the file name set as fixed, a single character with the last bit of the file name set as fixed, and a plurality of characters with the last few bits of the file name set as fixed. The fixed plurality of characters may be the same character or different characters, which is not limited in the present application.

In an embodiment of the present application, as shown in fig. 12, after the preview image is displayed on the photographed preview interface, the electronic device obtains the first type image in response to a second operation (e.g., a click operation on the photographing operation control) of the user. In order to ensure the stability of the photographing light, the flash may be set to be turned off.

The second operation is used for acquiring the first type of image, and the second operation can be a key triggering operation (such as simultaneously pressing an amplifying volume key and a reducing volume key) input through a mechanical key, a preset operation or a screen triggering operation of a preset gesture input through a touch screen, an image recognition triggering operation of a specific image acquired through a camera, a voice triggering operation of preset voice received through an audio module, and a wireless triggering operation sent by other electronic equipment.

In one example, after the first type of image is acquired, the electronic device may not display the first type of image, directly buffer the first type of image, and jump to the next step.

In another example, as shown in fig. 13, after the first type of image is acquired, the electronic device may also display the first type of image and display a hint operation control including a re-beat control and a continue control to jump to the next step. The electronic device may prompt the user to capture the first type of image again in response to a click operation on the re-capture control, and re-capture the first type of image if a second operation is received again. The electronic device may also jump to the next step in response to a click operation on the continue control. In this repeated operation, a first type image satisfying the user is acquired.

Optionally, in the embodiment of the present application, after the first type of image is acquired, the electronic device may further detect whether the first type of image is a front face image, and jump to the next step if the first type of image is a front face image; in the case where the first type image is not a front face image, the first type image is reacquired or the process jumps to the next step in response to an operation by the user.

For example, after the preview image shown in (a) of fig. 14 is acquired by the captured preview interface, after the first type image is acquired and displayed in response to the clicking operation of the capturing operation control by the user, if the first type image is not the front face image through detection, as shown in (b) of fig. 14, the prompt information, the re-capturing control, and the continuing control may be further re-captured, where the re-capturing prompt information is that the front face image is requested to be captured. Thereafter, as shown in (c) in fig. 14, the electronic device deletes the first type image in response to the click operation of the user on the re-shooting control, and redisplays the preview interface for capturing the shots of the first type image as shown in (d) in fig. 14. Alternatively, as shown in (e) of fig. 14, the electronic device jumps to the next step in response to the click operation of the user on the continuation control, and displays a preview interface for capturing a photograph of the second type image as shown in (f) of fig. 14.

Wherein the re-beat control and the continue control can be operated in response to a single click, double click, or long press. After the first type image, the re-shooting prompt information, the re-shooting control and the continuous control are displayed, if the click operation of the user is not received after the preset time, the electronic equipment defaults to delete the first type image according to the click operation of the re-shooting control, and a shooting preview interface for shooting the first type image is redisplayed.

In this way, after the first type image is acquired, before the next step is executed, the first type image, the re-shooting prompt information, the re-shooting control and the continuing control are displayed so as to receive clicking operation of the re-shooting control or the continuing control, and acquire the first image which can be satisfied by the user.

Optionally, in the embodiment of the present application, before responding to the second operation of the user, the electronic device may further detect whether the preview image displayed on the photographed preview interface is a front face image; if the detection result is no, displaying adjustment prompt information shown in (a) in fig. 15, wherein the adjustment prompt information is used for prompting a user to adjust the distance and the angle between the face and the camera so as to acquire a preview image meeting the requirements; if the detection result is yes, an operation prompt message as shown in (b) in fig. 15 is displayed.

It should be understood that the adjustment prompt is determined according to the actual display state of the preview image, for example, please move the face upward, please move the face downward, please turn the head right, please turn the head left, and so on. The operation prompt information is used for prompting the user to input a second operation.

In this way, the preview image in the shot preview interface is detected whether to be the front face image, and the adjustment prompt information prompt is displayed, and the prompt information of the second operation is displayed and input under the condition that the preview image is the front face image, so that the probability that the first type image meets the user requirement can be improved.

Further optionally, in an embodiment of the present application, the electronic device detects whether the preview image or the first type image is a front face image, and specifically includes: and acquiring a face coordinate list corresponding to the preview image or the first type image, wherein the face coordinate list comprises two groups of coordinates of a face rectangular frame, left and right eye coordinates, nose coordinates and left and right mouth corner coordinates. Under the condition that a null value exists in a list value in the face coordinate list, determining that the first type image is not a positive face image; and determining that the preview image or the first type image is a front face image when the list value in the face coordinate list does not have a null value.

Therefore, through the method, the first type image can be ensured to be the front face image, so that the probability that the custom beauty parameters obtained according to the first type image meet the requirements of users is improved.

Optionally, in the embodiment of the present application, after prompting to capture the first type of image, the electronic device may further display the gallery interface in response to an image importing operation of the user, then select a target image from the gallery in response to a selection operation of the user for the image in the gallery interface, then display the target image on a captured preview interface, and finally obtain the first type of image in response to a second operation of the user.

Thus, the first type of image is obtained by importing the saved image from the gallery, so that when the environment where the user is located is not suitable for changing the face dressing attribute (namely, the face dressing state is changed from the makeup carrying state to the makeup carrying state or the face dressing state is changed from the makeup carrying state to the makeup removing state), the custom face can be obtained Yan Canshu, the environmental limit for obtaining the custom face parameter is reduced, and the environmental adaptability for obtaining the custom face function is improved. Meanwhile, a user can shoot a plurality of images in a plain state or a makeup state at the same time, and select a most satisfactory image from the images as a first type image, so that the problem that the satisfaction of a photo shot by the user in time is not high can be solved, and whether the user repeatedly acquires the first type image in the process of acquiring the custom beauty parameters can be avoided, and the efficiency of acquiring the custom beauty parameters is improved.

It should be noted that, in order to obtain the custom beauty parameters, the face image of the face with the makeup needs to be obtained, and in combination with the actual life scene, the makeup process from the face state to the makeup state or the makeup removal process from the makeup state to the face state may need a long time for any user's face makeup attribute. In this period, the electronic device may exit the photographing application, or the photographing application is in a background running state, and further, may cause interruption in the operation flow of acquiring the custom beauty parameters. Thus, the electronic device can set the beauty effect collection control to include an effect collection menu. The effect acquisition menu comprises a first image acquisition control and a second image acquisition control. If the operation interruption sent after the first type image is acquired is detected, the first type image is saved, the first type image is marked by the first type image acquisition control in the effect acquisition menu, the first type image is identified to be acquired, and after the first type image is saved, if the clicking operation on the beautifying effect acquisition control is received again, the effect acquisition menu is displayed in response to the clicking operation on the beautifying effect acquisition control. And, the electronic device may re-prompt the shooting of the first type of image in response to a click operation of the user on the capture first type of image control, and acquire the first type of image in response to a second operation. The electronic device can also jump to the next step in response to a click operation by the user on the capture second type image control.

Step 403, the electronic device prompts the user to shoot the second type of image, and the second type of image is acquired in response to the third operation of the user.

In the embodiment of the present application, the prompting mode for prompting the user to shoot the second type image and the prompting mode for prompting the user to shoot the first type image are not described herein. The second type image includes the same face image as the first type image, and the second type image is different from the first type image.

In the embodiment of the application, when the first type image is a face image of a plain face, the second type image is a face image with makeup, which comprises the same face image as the first type image; alternatively, in the case where the first type image is a makeup-carrying face image, the second type image is a plain face image that includes the same face image as the first type image.

In one example, if the detected result of the first type of image is a face image with a face, the second type of image should be a face image with makeup, and the image capturing requirement may be to prompt the user to make up or similar information, as shown in fig. 16, please draw a satisfactory makeup for himself.

In another example, if the detected result of the first type of image is a face image with makeup, the second type of image should be a face image with plain color, and the image capturing requirement may be a prompt to ask the user to remove makeup or similar information.

In the embodiment of the present application, after the first type image is acquired, as shown in fig. 16, the electronic device displays the photographed preview interface again. And the electronic equipment displays prompt information for prompting the user to shoot the second type of image on the shot preview interface. And the electronic equipment can also display the preview image acquired by the camera on a shot preview interface. The electronic device may receive a third operation of the user at the photographed preview interface, and acquire the second type image in response to the third operation.

Wherein the third operation is for acquiring a second type of image. In the embodiment of the application, the third operation may be a key triggering operation (for example, a volume enlarging key and a volume reducing key are pressed for a long time) input through a mechanical key, a preset operation or a screen triggering operation of a preset gesture input through a touch screen, an image recognition triggering operation of a specific image acquired through a camera, a voice triggering operation of preset voice received through an audio module, or a wireless triggering operation sent by other electronic devices.

Optionally, in the embodiment of the present application, the electronic device may further recognize a gesture through an interface control or a screen on the photographed preview interface, and return to the previous step to reacquire the first type image. The user can distinguish whether the currently photographed preview interface is used for acquiring the first type of image or the second type of image through the displayed prompt information.

Illustratively, as shown in (a) of fig. 17, the user moves the distance and angle between the electronic device and the user according to the prompt information as shown in fig. 16 so that the target image is displayed at the photographed preview interface. The electronic device also displays prompt information on the preview interface of the shooting, for example, please draw a satisfactory makeup for himself, please shoot a face image with makeup, and place the face in the face frame. And then, the electronic equipment responds to the click operation of the shooting control by the user to acquire a second image. After the second image is acquired, the electronic device may not display the second type of image, directly buffer the second type of image, and jump to the next step. After the second type of image is acquired, as shown in (b) of fig. 17, the electronic device may further display the second type of image and display a prompt operation control including a re-shooting control and an acquire beauty parameter control to jump to the next step. The electronic device may prompt the user to capture the second type of image again in response to a click operation on the re-capture control, and re-capture the second type of image if a third operation is received again. The electronic device may also jump to the next step in response to a click operation on the continue control. In this repeated operation, a second image satisfying the user is acquired.

In the embodiment of the application, the electronic device responds to the third operation of the user, and acquires the second type of image under the condition that the shooting trigger condition is met, wherein the shooting trigger condition comprises at least one of the following: the background similarity of the second type image compared with the first type image is larger than a first preset threshold value, the ambient light similarity of the second type image compared with the first type image is larger than a second preset threshold value, and the shooting parameters of the second type image compared with the first type image are the same. The closer the first preset threshold value and the second preset threshold value are to 100%, the more the obtained custom beauty parameters can meet the requirements of users. The flash states in the shooting parameters corresponding to the first type of image are all off states. Wherein ambient light may include light intensity and light color.

Further optionally, in the embodiment of the present application, after receiving the third operation of the user, if the shooting trigger condition is not satisfied, the electronic device detects whether the shooting trigger condition is satisfied again until it is detected that the shooting trigger condition is satisfied to acquire the second type image. If the third operation is received again after the third operation of the user is received and within a period of time when the shooting trigger condition is not satisfied, the electronic device responds to the third operation once after the shooting trigger condition is satisfied.

It should be further noted that the capturing of the first type image and the second type image under the indoor light may be selected to increase the probability that the similarity of the ambient light of the second type image to the first type image is greater than the second preset threshold.

Generally, in order to meet the personalized requirements of users on the beauty images, custom beauty Yan Canshu needs to be obtained, and the beauty treatment is performed on the face images of the users, and the custom beauty parameters are generally applied to the owners of the electronic devices, that is, the owners of the electronic devices. Therefore, the electronic device can set the authority for acquiring the custom beauty parameters in a face recognition mode, and specifically comprises the following steps: and carrying out face recognition on the face image in the shot preview interface, and acquiring a first type image and a second type image under the condition that the face image is consistent with the face of the user.

Optionally, in the embodiment of the present application, after prompting to capture the second type of image, the electronic device may further display a gallery interface in response to an image importing operation of the user, and then, the electronic device selects the target image from the gallery in response to a selection operation of the user for the image in the gallery interface. And finally, the electronic equipment responds to a third operation of the user to acquire a second type image.

Thus, by importing the saved images from the gallery, the second type of image is obtained, so that when the environment where the user is located is not suitable for changing the face dressing attribute (i.e. the face dressing state is changed from the makeup carrying state to the makeup carrying state or the face dressing state is removed from the makeup carrying state to the makeup carrying state), the custom beauty Yan Canshu can also be obtained, so that the environmental limitation of obtaining the custom beauty parameters is reduced, and the environmental adaptability of obtaining the custom beauty function is improved. Meanwhile, the user can shoot a plurality of images in the plain or makeup state at the same time, and select one of the most satisfactory images as a second type image for acquiring the custom beauty parameters, so that the problem of low satisfaction of the photos shot by the user in time can be solved, and whether the user repeatedly acquires the second type image in the process of acquiring the custom beauty parameters can be avoided, and the efficiency of acquiring the custom beauty parameters is improved.

It should be noted that the electronic device may set the beautifying effect collection control to include an effect collection menu. The effect acquisition menu comprises a first image acquisition control and a second image acquisition control. If the operation interruption sent before the second type image is acquired is detected, the electronic equipment stores the first type image, marks the first type image acquisition control in the effect acquisition menu, and identifies that the first type image is acquired. If the operation interruption sent after the second type of image is acquired is detected, the electronic equipment stores the first type of image and the second type of image, marks the acquired first type of image in the effect acquisition menu, marks the acquired first type of image, marks the acquired second type of image in the effect acquisition menu, and marks the acquired second type of image. Then, after the first type image or the first type image and the second type image are saved, if the clicking operation of the beautifying effect acquisition control is received again, the electronic equipment responds to the clicking operation of the beautifying effect acquisition control and displays the effect acquisition menu. And the electronic device may re-prompt the shooting of the first type of image in response to a click operation of the user on the capture of the first type of image control and acquire the first type of image in response to a second operation, or re-prompt the shooting of the second type of image in response to a click operation of the user on the capture of the second type of image control and acquire the second type of image in response to a third operation.

Step 404, the electronic device obtains the custom beauty parameters according to the first type image and the second type image.

Optionally, in the embodiment of the present application, the electronic device determines the face image of the plain face (as shown in fig. 13) and the face image of the makeup face (as shown in fig. 17 (b)) according to a default setting manner or an image identifier, and obtains the custom beauty parameters according to the pixel difference between the face image of the plain face and the face image of the makeup face. The process of acquiring the beauty parameters may be implemented by an image processing chip or by a processor in the electronic device (in which the application program having the function of determining the beauty parameters is installed). It should be noted that if the first type image is a face image of a plain face, the second type image is a face image of a makeup-carrying face, and conversely, if the first type image is a face image of a makeup-carrying face, the second type image is a face image of a plain face.

In the embodiment of the present application, the custom beauty parameter is a Look-Up Table (LUT), which may also be called a LUT file or LUT parameter, and is a mapping Table of Red Green Blue (RGB). Specifically, an image includes a plurality of pixels, each pixel being represented by an RGB value. The display screen of the electronic device may display the image according to the RGB values for each pixel in the image. That is, these RGB values tell the display how to illuminate to mix out the various colors for presentation to the user. If it is desired to change the color (or style, effect) of the image, these RGB values may be adjusted. The LUT is an RGB mapping table, which is used to characterize the correspondence between RGB values before and after adjustment. For example, please refer to table 1, which shows an example of a LUT.

TABLE 1

When the original RGB value is (14,22,24), the output RGB value is (6,9,4) through the mapping of the LUT shown in table 1. When the original RGB value is (61,34,67), the output RGB value is (66,17,47) through the mapping of the LUT shown in table 1. When the original RGB value is (94,14,171), the output RGB value is (117,82,187) through the mapping of the LUT shown in table 1. When the original RGB value is (241,216,222), the output RGB value is (255,247,243) through the mapping of the LUT shown in table 1.

The display effect of the image processed by the LUT is different from the display effect of the image processed by the LUT for the same image; and different LUTs are adopted to process the same image, so that display effects of different styles can be obtained. The "display effect" of the image in the embodiment of the application refers to an image effect that can be observed by human eyes after the image is displayed by the display screen.

In the embodiment of the application, because the face images contained in the face images with the plain face and the face images with the makeup are highly similar, only the difference of effect dimensions such as color, brightness and the like exists, the colors of the face images with the plain face and the face areas with the face images with the makeup can be extracted from pixel to pixel respectively, and a mapping relation of pixel level is established, and the mapping relation is used for representing the difference between the state with the plain face and the state with the makeup, namely, the mapping relation is equivalent to the self-defined beauty parameters.

Optionally, in the embodiment of the present application, the electronic device may first detect a face key point of a face image of a plain face or a face image with makeup, divide the face into a plurality of regions based on the key point, then extract color information of each region, and finally establish a pixel-level correspondence with respect to the face regions corresponding to the face image of the plain face and the face image with makeup, and generate the LUT, so as to improve a speed of obtaining the custom beauty parameter.

Further alternatively, in the embodiment of the present application, according to the general implementation concept: firstly, carrying out region division on a first image and a second image, and then comparing pixel differences of each group of corresponding face regions to obtain custom beautifying parameters. As shown in fig. 18, this step 404 may also be implemented by the following steps 1801 to 1802.

Step 1801, the electronic device divides the face image of the plain face into at least one first face region through a preset face region division algorithm, and divides the face image of the makeup face into at least one second face region through the preset face region division algorithm.

In step 1802, the electronic device obtains a custom beauty parameter according to the region type of the first face region, and the second face region corresponding to the first face region.

In the embodiment of the application, the face image with the face is a first type image or a second type image, and the face image with the makeup is a second type image or a first type image. The first face area corresponds to the second face area one by one, and the area types comprise uniform color area types and color difference area types. It can be understood that, because the face image of the plain face and the face image of the makeup face both conform to the boundary limit of the face frame, the size of the image as a whole, the face position and the facial feature position in the face are similar, so that the first face region and the second face region divided according to the same preset face region division algorithm correspond one by one.

Further optionally, in the embodiment of the present application, in the step 1801, the plain face image is divided into at least one first face area by a preset face area segmentation algorithm, which is specifically implemented as follows: training an active shape model (Active Shape Model, ASM) according to a preset sample, wherein the preset sample is a face image with facial feature point identifications; the face images of the plain faces are input into a trained ASM, acquiring a first search feature point of a face image of a plain face; and constructing a shape vector of the face region according to the first search feature points to obtain at least one first face region.

In the embodiment of the application, ASM is a method for extracting a shape based on a feature point distribution model (Point Distribution Model, PDM), in which geometric shapes of objects with similar shapes, such as a face, a hand, a heart, a lung and the like, can be sequentially connected in series through coordinates of a plurality of key feature points to form a shape vector. In the ASM training process, training samples are collected, facial feature points of people are marked, shape vectors are constructed, normalization and alignment are carried out on all face images, and local features are constructed for each feature point, so that ASM training is achieved. After training is completed, feature points can be searched in the face of the face image of the plain face according to the trained ASM, and the region segmentation result of the face feature points can be obtained. Thus, the first face region obtained by constructing the face region through the first search feature points obtained by the ASM has higher similarity with the outline of the facial features and corresponds to the actual cosmetic region, so that the accuracy of judging the region type corresponding to the first face region can be improved, and the satisfaction degree for self-defining the cosmetic parameters is further improved.

It can be appreciated that, similar to the above-mentioned process of dividing the face image with the face, in step 1801, the face image with the make-up is divided into at least one second face region by a preset face region dividing algorithm, which specifically includes: training ASM according to a preset sample, wherein the preset sample is a face image with facial feature point marks; inputting the face image with makeup into a trained ASM, and acquiring a first search feature point of the face image with makeup; and constructing a shape vector of the face region according to the first search feature points to obtain at least one first face region. The dividing process of the second face area corresponding to the face image with makeup is not described herein.

In the embodiment of the present application, other dividing methods may be adopted for the dividing manner of the face area, which is not limited herein.

Therefore, the first face region is classified according to the cosmetic effect characteristics (the region types comprise uniform color region types and different color region types), and then the color mapping relation between the plain face image and the face image with the cosmetic is established according to different region types, so that the acquisition efficiency of the custom face parameters can be improved.

Further optionally, in an embodiment of the present application, before obtaining the custom beauty Yan Canshu, the electronic device may further determine a region type of each of the at least one first face region. Specifically, the electronic device may determine the region type of the first face region that is more uniform and smooth in the image feature as a color uniformity region type. The judging method of the region type specifically comprises the following steps: acquiring a first color component mean value of pixels in an area of a first face area and a second color component mean value of pixels in an image of a plain face image, wherein the first color component mean value comprises: the first R component average, the first G component average, and the first B component average, the second color component average comprising: a second R component average, a second G component average, and a second B component average; comparing the first color component mean value with the second color component mean value; determining that the region type of the first face region is a uniform color type under the condition that the average difference between the first color component average value and the second color component average value is smaller than a third preset threshold value; and determining the region type of the first face region as a color difference type under the condition that the average difference between the first color component mean value and the second color component mean value is greater than or equal to a third preset threshold value.

It can be understood that the face area corresponding to the color uniformity type is uniform and flat, and the face area corresponding to the color difference type is rich in detail texture. The third preset threshold may be set to 10% by way of example.

Therefore, the color is the main difference between the face image with the plain face and the face image with the makeup face, and the region type of the first face region is judged according to the color component mean value, so that the pixel distribution characteristics of the same region type are similar, the accuracy of adopting different mapping modes aiming at different region types can be improved, and the speed of obtaining the custom face parameters can be improved.

In an example, under the condition that the region type of the first face region is of a uniform color type, the electronic device establishes a mapping relationship between the first face region and the second face region in a pixel-by-pixel mapping mode according to the first face region and the second face region corresponding to the first face region; under the condition that the region type of the first face region is a color difference type, the electronic equipment establishes a mapping relation between the first face region and the second face region by adopting a region average pixel integral mapping mode according to the first face region and the second face region corresponding to the first face region; and the electronic equipment determines the parameters in the mapping relation as custom beauty parameters.

In another example, when the region type of the first face region is a color difference type, the electronic device divides the first face region into at least one first rectangular region according to a preset region size with a first pixel point in the first face region as a starting point, and obtains a pixel average value of each first rectangular region in the at least one first rectangular region; the electronic equipment divides the second face area into at least one second rectangular area according to the size of a preset area by taking a second pixel point in the second face area as a starting point, and acquires the pixel average value of each second rectangular area in the at least one second rectangular area, wherein the first pixel point corresponds to the second pixel point; the electronic equipment establishes a mapping relation between the pixel average value of the first rectangular area and the pixel average value of the second rectangular area. The preset area size may be set to include 10000 pixels, for example.

It should be noted that the mapping relationship in the above example is implemented by the LUT. In terms of image processing, the LUT can be used to accomplish filter-like effects, the principle being that a mapping relationship, input colors (R, G, B), look up through the LUT, etc. to a new color (R, G, B), a mapping operation is accomplished. The LUT essentially belongs to the replacement of individual pixels, so that each pixel corresponds to a new color value.

It can be understood that, because the face image content in the face image with the face is highly similar to the face image content in the face image with the face, only the difference of the effect dimensions such as color, brightness and the like exists, the first face region and the color of the second face region corresponding to the first face region are extracted from pixel to pixel respectively, and a pixel-level mapping relation is established, namely, the difference between the face state and the face state of the same face is equivalent to the user-defined beauty parameters.

The method includes the steps of selecting a target first face region containing an eye region in at least one first face region and a target second face region corresponding to the target first face region, extracting pixel values (R, G, B) of target pixel points in the target first face region as an original value 1, extracting pixel values (R, G, B) of opposite pixel points in the target second face region corresponding to the target pixel points as an output value 1, and the like, acquiring complete original values and output values of the eye region, and storing all information as an LUT (look-up table) representing a color mapping relation, wherein the LUT is a user-defined eye region beauty parameter. When the face image captured by the camera comprises an eye area, the LUT is applied to the eye area of the face image captured currently, and a mapping is built according to the corresponding relation of the lookup table, so that the effect of the eye area after beautification is achieved.

Therefore, the user-defined beautifying parameters are determined by adopting different mapping modes according to different region types, and the speed of obtaining the user-defined beautifying parameters can be improved.

Optionally, in the embodiment of the present application, after obtaining the custom beauty parameters, the electronic device may detect whether the custom beauty parameters exist, directly store the custom beauty parameters if the custom beauty parameters do not exist, and display a prompt control if the custom beauty parameters exist, so as to prompt the user to select to replace the existing custom beauty parameters, or add a data item to store the custom beauty parameters. And the electronic equipment responds to an operation instruction of selecting a storage mode of the prompt control by a user, and stores the custom beauty parameters according to the corresponding storage mode. Therefore, a plurality of custom beauty Yan Canshu can be saved so as to meet the requirement of users on diversification of custom beauty parameters. It can be understood that, in order to balance the system resources and the user demands, the storage quantity of the custom beauty parameters can be set, and once the storage upper limit is reached, the custom beauty parameters cannot be stored in a new mode.

In the embodiment of the application, because the requirements of the user on the beauty treatment are different, the daily decoration of the user is different, and therefore, the first type of image can be a plain face image, a face image with makeup or a face image imitating makeup. The second type of image may be a plain face image, a vanity face image, or an image of a vanity face image that is different from the first type of image. Assuming that the first type of image is a face image with a face and the second type of image is a face image with a face, the face image with the face can be obtained by processing the face image with the face according to the self-defined face beautifying parameters. And if the first type of image is a plain face image and the second type of image is a makeup-like face image, processing the plain face image according to the user-defined beauty parameters to obtain the makeup-like face image. And if the first type of image is a makeup-carrying face image and the second type of image is a makeup-simulating face image, the makeup-carrying face image is processed according to the user-defined beauty parameters to obtain the makeup-simulating face image.

According to the method for acquiring the beauty parameters, the first operation, the second operation and the third operation are sequentially responded to obtain the custom beauty parameters, repeated debugging of the beauty parameters according to the beauty effect is not needed, and the operation steps are simple and time consumption is short. The face image with make-up can be understood as the face effect expected to be achieved by the user, so that the face image which is photographed daily can achieve the face effect satisfied by the user by adopting the face image which is obtained after the face treatment is carried out by adopting the custom face parameters.

In the embodiment of the application, the face image in the first image and the face image contained in the first type image or the second type image are the same face image. Assuming that an image acquired by a camera of the electronic device is a first image as shown in (a) of fig. 19, processing the first image according to the custom beauty parameters to obtain a second image as shown in (b) of fig. 19.

After the user-defined beautifying parameters are obtained, the electronic device can default to adjust a switch on the right side of the user-defined beautifying effect control in the effect selection interface to be in an on state, and a second image obtained by processing the third image according to the user-defined beautifying parameters is displayed on the shot preview interface.

It should be further noted that, after obtaining the custom beautifying parameters, the electronic device may default to adjust the switch on the right side of the "custom beautifying effect" control in the effect selection interface to the off state. The electronic equipment displays the acquired first image on a shot preview interface; the electronic equipment responds to a fourth operation of a user and displays a second image obtained by processing the first image according to the user-defined beautifying parameters; the fourth operation is used for triggering and starting the beautifying effect.

In this way, by responding to the fourth operation of the user for the custom beauty application control, the second image is displayed on the shooting preview interface, so that the user can select to display the first image without beauty according to the instant requirement or process the second image after the first image according to the custom beauty parameter, and the diversified requirement of the user for the shot preview interface display is met. The user can observe the beauty effect image (second image) through the preview interface in real time, so that the shooting speed of the user is improved, and further, system resources such as electric quantity, residual available pressing times, system progress number and the like are saved.

Further optionally, the method for obtaining the beauty parameters provided by the embodiment of the application further includes: the electronic equipment sends out beauty prompt information which is used for prompting the second image to be an image obtained by processing the first image according to the custom beauty parameters.

The beautifying prompt information can be text prompt information, image prompt information or voice prompt information. It should be understood that, similar to other prompt information, the beauty prompt information may be text information, graphic information or sound information, and sent by using a display screen or a sound tube as a carrier, for example, the beauty prompt information is displayed or played.

For example, as shown in fig. 20, while the second image is displayed on the photographed preview interface, the "beautified" beautification prompt information is displayed on the top of the second image.

Further optionally, in an embodiment of the present application, after displaying the second image, a method for obtaining a beauty parameter provided in the embodiment of the present application further includes: the electronic device displays an image editing interface in response to a fifth operation on the second image, the image editing interface including one or more controls for editing the second image. And the second image can be reprocessed through one or more controls in the image editing interface so as to meet the diversified editing requirements of users on the image.

In the embodiment of the application, one or more controls can be used for adjusting the tone, the environment enhancement, the blurring, the rotation, the clipping, the shooting parameters, the filter, the picture matting, the scrawling, the mosaic addition, the special effect and the text addition and the like of the fourth image.

Wherein the fifth operation is for editing the second image. In the embodiment of the application, the fifth operation may be a key triggering operation (for example, a key for simultaneously pressing an up volume key and a down volume key) input through a mechanical key, a preset operation or a screen triggering operation of a preset gesture input through a touch screen, an image recognition triggering operation of a specific image acquired through a camera, a voice triggering operation of preset voice received through an audio module, or a wireless triggering operation sent by other electronic devices.

In some embodiments, as shown in fig. 21 (a), the image editing interface may be configured to display one or more controls on the basis of a photographed preview interface. The one or more controls include a hue control, an environment enhancement control, a blurring control, and the like.

In other embodiments, as shown in fig. 21 (b), the image editing interface is configured to display the second image and one or more controls after the second image is acquired. The one or more controls include a hue control, an environment enhancement control, a blurring control, and the like.

It should be noted that, the one or more controls include a beauty degree control bar, where the beauty degree control bar is used to adjust a strength of performing a beauty treatment on the second image by using custom beauty Yan Canshu, and after displaying the image editing interface, the method for obtaining the beauty parameters provided by the embodiment of the present application further includes: the electronic equipment responds to the adjustment operation of the user on the beauty degree control bar, and a third image is displayed; the third image is an image obtained by processing the second image according to the strength of the beauty treatment corresponding to the adjusted beauty degree control bar and the custom beauty parameters.

Illustratively, the beauty treatment force can be changed by changing the mark position of the beauty degree control bar as shown in fig. 22 through a drag operation or a click operation. Taking the lip color as an example, the lip color in the plain face image is light pink, the lip color in the makeup face image is bright red, namely the lip color in the collected first image is light pink, and the lip color in the second image is bright red. Because the color of the reddish shade is more prominent and may not match with the hair color in the second image, the adjustment operation of the beauty degree control bar by the user may be received, and the mark position is adjusted to the middle position, that is, the strength of the beauty treatment corresponding to the beauty degree control bar is 50%. Assuming that RGB of the pixel corresponding to the lip in the first image is (255,192,203), RGB of the pixel corresponding to the lip in the second image is (255, 0), RGB of the pixel corresponding to the lip in the third image is (255,96,101).

In one example, if the second image is an image displayed at the photographed preview interface, the electronic device may display the third image at the photographed preview interface or obtain the third image after the image editing interface displays the third image in response to the user's operation.

In another example, if the second image is a captured image, the electronic device may capture the third image after the image editing interface displays the third image in response to a user operation.

Therefore, the second image can be reprocessed through the editing effect control in the image editing interface so as to meet the diversified editing requirements of users on the image effect.

Further optionally, in an embodiment of the present application, the electronic device may set the first image as an image acquired by the front camera. Under the condition that a user starts the front camera, the electronic equipment sets the automatic application custom beauty parameters to carry out beauty treatment on the captured preview image. The preview image includes a face image in the first type image or the second type image.

Further optionally, in an embodiment of the present application, the electronic device may further set the first image as an image acquired by the rear camera. Because the rear camera is generally used for shooting scenes or group images, in the case that a user starts the rear camera, the electronic device sets whether to apply custom beauty parameters to perform beauty treatment on the captured preview image according to user operation, wherein the preview image comprises a face image. It can be understood that, in order to ensure the adaptability of the custom beauty parameters and the face image, the electronic device may further set to acquire a target partial image in the preview image, and perform the beauty treatment on the target partial image according to the custom beauty parameters, where the target partial image is a partial image of the face image in the preview image including the first type image or the second type image.

Alternatively, in the embodiment of the present application, as shown in fig. 23, the above step 404 may also be implemented by the following steps 2301 and 2302.

In step 2301, when it is detected that the first type image and the second type image need to be subjected to a concealing process, the electronic device performs the concealing process on the first type image and the second type image according to a preset concealing algorithm, and updates the first type image and the second type image.

And 2302, the electronic device compares the pixel difference between the updated first type image and the updated second type image to obtain the custom beauty parameters.

Taking the first type image as an example, the electronic device may divide the first type image into a skin area and a five sense organs area, then determine whether a flaw exists in the skin area of the first type image and a flaw location, and finally perform a flaw removal process according to the flaw location.

It should be noted that, similar to the method of performing the concealing treatment on the second type image, the electronic device may use dividing the skin area to determine whether there is a flaw and a flaw position in the skin area of the second type image, and finally perform the concealing treatment according to the flaw position.

It can be understood that, in the method for performing the flaw removal processing on the second type image, the electronic device may determine whether a flaw exists in the skin area of the first type image and the flaw position according to the flaw position of the skin area of the first type image, and if so, perform the flaw removal processing.

Further alternatively, in the embodiment of the present application, the blemish that can be detected by the electronic device may be a blemish skin, such as a acne mark, a nevus, a wrinkle, or an effect that may be represented by makeup, so, in order to obtain the actual concealer removal intention of the user, it may be set after the first type image and the second type image are obtained, in response to the concealer removal selection operation input by the user, it is determined whether concealer removal is performed, and then it is detected whether concealer removal is required for the first type image and the second type image.

It can be understood that, for selecting whether to perform the concealing process, the electronic device may further set and record the concealing selection operation instruction input by the user, which is used as a default processing manner, so as to reduce the necessary steps required for obtaining the custom beauty parameters and obtain the efficiency of the custom beauty parameters. Alternatively, a default processing method (may be performed for performing the concealer or not) may be set as to whether or not the concealer is selected, and if the concealer selection operation by the user is subsequently received, the concealer selection operation by the user is recorded as the default processing method.
