The method for adjusting the beauty parameters provided by the embodiment of the application is described in detail below by means of specific embodiments and application scenes thereof with reference to the accompanying drawings.

Fig. 1 is a schematic flow chart of a method for adjusting a beauty parameter according to an embodiment of the present application, and an execution body of the method for adjusting a beauty parameter may be an electronic device.

In embodiments of the present application, the electronic device may be, but is not limited to, a personal computer (Personal Computer, PC), a smart phone, a tablet computer, or a personal digital assistant (Personal Digital Assistant, PDA), etc.

In an embodiment of the present application, the electronic device may have a beautifying function.

As shown in fig. 1, the method for adjusting the beauty parameters provided in the embodiment of the present application may include steps 110 to 130.

Step 110, acquiring first pose information of a target object at a first moment and second pose information of the target object at a second moment when the electronic device is in a photographing preview mode.

The first time may be any time.

The second moment in time may be any moment in time after the first moment in time, i.e. the first moment in time is earlier than the second moment in time.

The target object may be a face or an electronic device of a photographic person object in the photographic preview image. Specific implementations are described in detail in the examples that follow for both cases of the target object.

The first pose information may be pose information of the target object at a first time.

The second pose information may be pose information of the target object at a second moment in time.

In some embodiments of the present application, the first pose information and the second pose information may be obtained based on a pose detection algorithm in the electronic device, and specifically how to obtain the first pose information and the second pose information may be obtained according to a user requirement by using an existing obtaining means, which is not limited herein.

Step 120, determining pose change information of the target object based on the first pose information and the second pose information.

The pose change information may be change information of the target object from the first pose information to the second pose information. Specifically, the first pose information is subtracted from the second pose information, and the obtained difference value is pose change information.

And 130, adjusting the first beauty parameters corresponding to the first pose information based on the pose change information to obtain target beauty parameters corresponding to the second pose information.

The first beauty parameters may be beauty parameters obtained under the first pose information, and specifically may be beauty parameters preset under the first pose information.

The target beauty parameters may be the beauty parameters under the second pose information obtained after the first beauty parameters are adjusted.

In some embodiments of the present application, in order to more clearly understand how to adjust the beauty parameters when the target object is the face of the photographed person object or the electronic device in the photographed preview image, the following two cases are described in detail:

(1) The target object is the face of the shooting person object in the shooting preview image

In some embodiments of the present application, in a case where the target object is a face of a photographed person object in the photographed preview image, in order to further enhance the user experience, step 120 may specifically include:

determining a first posture change type and a first change angle of the face based on the first posture information and the second posture information;

step 130 may specifically include:

and adjusting the first beauty parameters corresponding to the first pose information based on the first pose change type and the first change angle to obtain target beauty parameters corresponding to the second pose information.

The first gesture change type may be a change type of a gesture of the face after the face is changed from the first gesture information to the second gesture information. The first posture change type here may be head up, head down, or face side.

In one example, referring to fig. 3, if the first pose information is pose information of the face in a head-up state and the second pose information is pose information in a top-down state, the face is changed from the head-up state to the top-down state, and the user is low, the first pose change type is low. If the second pose information is pose information in the looking-up state, the face is changed from the looking-up state to the looking-up state, and the user heads up, and the first pose change type is head up. If the second pose information is pose information in a side face state, the face is changed from a head-up state to a side face state, and the user heads up, the first pose change type is a side face (i.e., left side of the face or right side of the face in fig. 3).

The first change angle may be a change angle of the posture of the face after the face is changed from the first posture information to the second posture information.

In some embodiments of the present application, face pose changes and angles of change may be acquired based on face detection software development kits (Software Development Kit, SDK) in the electronic device.

In the embodiment of the application, the first gesture change type and the first change angle of the face can be accurately determined through the first gesture information and the second gesture information, then the first beauty parameters corresponding to the first gesture information are accurately adjusted based on the first gesture change type and the first change angle, and the accurate target beauty parameters corresponding to the second gesture information are obtained.

(2) The target object being an electronic device

In some embodiments of the present application, in the case where the target object is an electronic device, in order to further enhance the user experience, step 120 may specifically include:

determining a second gesture change type and a second change angle of the electronic equipment based on the first gesture information and the second gesture information;

Step 130 may specifically include:

and adjusting the first beauty parameters corresponding to the first pose information based on the second pose change type and the second change angle to obtain target beauty parameters corresponding to the second pose information.

The second gesture change type may be a change type of gesture of the electronic device after the electronic device is changed from the first gesture information to the second gesture information. The second gesture change type here may be an electronic device up, down, or translation.

In one example, referring to fig. 4, if the first pose information is pose information of the electronic device in a vertical horizontal state, and the second pose information is pose information of the electronic device rotated by one angle, the electronic device is changed from the first pose information to the second pose information, and the electronic device is translated from a front face of a photographing user to a side face of the photographing user.

The second change angle may be a change angle of the posture of the electronic device after the electronic device is changed from the first posture information to the second posture information.

In some embodiments of the present application, the first pose information and the second pose information may be calculated based on gyroscope data in the electronic device.

In the embodiment of the application, the second gesture change type and the second change angle of the electronic equipment can be accurately determined through the first gesture information and the second gesture information, then the first beauty parameters corresponding to the first gesture information are accurately adjusted based on the second gesture change type and the second change angle, and the accurate target beauty parameters corresponding to the second gesture information are obtained.

In some embodiments of the present application, in order to further improve user experience, when determining the second change angle of the electronic device according to the first pose information and the second pose information, the method may specifically be:

and determining a second change angle of the electronic equipment in each direction based on the first pose information and the second pose information.

The second change angle of the electronic device in each direction may be a change angle of the electronic device in each direction in a state corresponding to the second pose information.

In the embodiment of the application, the second change angle of the electronic equipment in each direction can be accurately determined through the first pose information and the second pose information, so that the target beautifying parameters under the second pose information can be further determined, the beautifying effect can be different from person to person, the personalized requirements of a user are met, and the user experience is further improved.

In some embodiments of the present application, in order to further obtain accurate target beauty parameters, adjusting the first beauty parameters corresponding to the first pose information based on the target pose change type and the target change angle to obtain target beauty parameters corresponding to the second pose information may include:

based on the target attitude change type, the target change angle and the beauty parameter adjustment coefficient, adjusting a first beauty parameter corresponding to the first pose information to obtain a target beauty parameter corresponding to the second pose information;

wherein the target gesture change type may be a first gesture change type or a second gesture change type.

The target variation angle may be the first variation angle or the second variation angle. Specifically, when the target posture change type is the first posture change type, the target change angle is the first change angle; when the target posture change type is the second posture change type, the target change angle is the second change angle.

The beauty parameter adjustment coefficient may be a coefficient related to at least one of the posture change type and the beauty parameter type.

In the embodiment of the application, the first beauty parameter corresponding to the first pose information is adjusted based on the target pose change type, the target change angle and the beauty parameter adjustment coefficient to obtain the target beauty parameter corresponding to the second pose information, and the beauty parameter adjustment coefficient is related to at least one of the pose change type and the beauty parameter type, so that the corresponding beauty parameter adjustment coefficient can be selected based on the pose change type and the beauty parameter type, further the accurate target beauty parameter is obtained, and the accuracy of the target beauty parameter is improved.

In some embodiments of the present application, in order to further obtain accurate target beauty parameters, the adjusting the first beauty parameters corresponding to the first pose information based on the target pose change type, the target change angle, and the beauty parameter adjustment coefficient to obtain target beauty parameters corresponding to the second pose information may specifically include:

selecting a first target beauty parameter adjustment coefficient corresponding to the target attitude change type from the beauty parameter adjustment coefficient group based on the target attitude change type;

and adjusting the first beauty parameters corresponding to the first pose information based on the target pose change type, the target change angle and the first target beauty parameter adjustment coefficient to obtain target beauty parameters corresponding to the second pose information.

Wherein, the liquid crystal display device comprises a liquid crystal display device,

the set of parameters for the adjustment of the beauty parameters may be a set of coefficients for the adjustment of the beauty parameters. The beauty parameter adjustment coefficient group may include beauty parameter adjustment coefficients corresponding to different gesture change types and different beauty parameter types.

The first target beauty parameter adjustment coefficient may be a beauty parameter adjustment coefficient corresponding to the target attitude change type selected from the beauty parameter adjustment coefficient group based on the target attitude change type.

In one example, the set of beauty parameter adjustment coefficients may be an array, such as [ a1, a2, a3], and if the target object is a face of a photographed person object in the photographed preview image, the first change type may include a head up, a low head, and a side face, a1 may be a beauty parameter adjustment coefficient corresponding to the head up type, a2 may be a beauty parameter adjustment coefficient corresponding to the low head type, and a3 may be a beauty parameter adjustment coefficient corresponding to the side face type.

When the beauty parameter adjustment coefficient is 0, the face is not dynamically adjusted, and the larger the beauty parameter adjustment coefficient is, the more obvious the final adjustment effect is. The dynamic adjustment coefficients are related to specific beauty terms, and the dynamic adjustment coefficient groups (i.e., the beauty parameter adjustment coefficient groups) corresponding to the beauty terms can be determined after the best effect is achieved, that is, the beauty parameter adjustment coefficient groups are obtained through experiments in advance.

In the embodiment of the application, through the target attitude change type, a first target beauty parameter adjustment coefficient corresponding to the target attitude change type is selected from the beauty parameter adjustment coefficient group, and then the first beauty parameter corresponding to the first pose information is adjusted based on the target attitude change type, the target change angle and the first target beauty parameter adjustment coefficient, so that the accurate target beauty parameter corresponding to the second pose information can be obtained.

In some embodiments of the present application, the selecting, based on the target attitude change type, the first target beauty parameter adjustment coefficient corresponding to the target attitude change type from the group of beauty parameter adjustment coefficients may specifically include:

dividing the face of a shooting person object in a shooting preview image according to a preset dividing mode to obtain at least one face area;

selecting a second target face parameter adjustment coefficient set corresponding to the target face region from at least one set of face parameter adjustment coefficient sets based on the target face region;

and selecting a first target beauty parameter adjustment coefficient corresponding to the target attitude change type from the second target beauty parameter adjustment coefficient group based on the target attitude change type.

The preset division method may be a preset division method, and is not limited herein, as long as the face of the photographed person object in the photographed preview image can be divided.

A face region corresponds to a type of beauty parameter. For example, the nose corresponds to one type of beauty parameter and the forehead corresponds to another type of beauty parameter.

The target face region may be any one of the at least one face region.

The second target face parameter adjustment coefficient set may be a face parameter adjustment coefficient set corresponding to the target face region selected from at least one set of face parameter adjustment coefficient sets based on the target face region.

In one example, the first pose information is pose information in a head-up state, the first beauty parameters are a forehead (30), a chin (45), a reaming distance (40), a face (50) and a nose (35), and the first beauty parameter adjustment coefficient groups corresponding to the first beauty parameters of the face areas are [ -0.1,0.1,0], [0.1, -0.05,0], [ -0.1,0.2, -0.2], [ -0.1,0.1, -0.1], [0.2,0,0.2]; in each of the beauty parameter adjustment coefficient groups, the first coefficient corresponds to a head-up type, the second coefficient corresponds to a low head type, and the third coefficient corresponds to a side face type.

When the face posture angle is detected to be 30 degrees, namely, the head-up angle of the user is indicated to be 30 degrees, firstly, according to the face area of the user, selecting a coefficient group corresponding to each face area (namely, a second target face-beautifying parameter adjustment coefficient group) from face parameter adjustment coefficient groups, then selecting a first coefficient from the coefficient groups corresponding to each face area according to the head-up of the user, and calculating an adjusted face-beautifying Yan Canshu (namely, target face-beautifying parameter):

Contraction forehead: 30+ (-0.1 x 30) =27;

chin shrinking: 45+0.1×30=48;

eye distance expansion: 40+ (-0.1 x 30) =37;

face thinning: 50+ (-0.1 x 30) =47;

augmentation of nose: 35+0.2x30=41.

Therefore, when the human face is raised, the chin becomes larger and the forehead becomes smaller, at this time, the parameters of the forehead and the eye part can be properly reduced if the forehead and the eyes become smaller by properly adjusting the angle of the human face (specifically, increasing the parameter enhancing effects of the chin, the small mouth and the like). The target beauty parameters after the adjustment are finished, and the coordination of all the beauty effects is increased.

In the embodiment of the application, the face of the shooting person object in the shooting preview image can be divided according to the preset division mode to obtain at least one face area, then a second target face parameter adjustment coefficient group corresponding to the target face area is selected from at least one group of face parameter adjustment coefficient groups based on the target face area, a first target face parameter adjustment coefficient corresponding to the target attitude change type is selected from the second target face parameter adjustment coefficient group based on the target attitude change type, and therefore the first target face parameter adjustment coefficient can be accurately determined, so that the target face parameters corresponding to the face areas under the adjusted second pose information are mutually matched, the requirement of a user on the face effect is met, and the user experience is improved.

In some embodiments of the present application, in order to further coordinate and match the face beautifying parameters of each face area, the dividing the face of the photographed person object in the photographed preview image according to a preset dividing manner to obtain at least one face area may include:

the face is divided in the horizontal direction and the vertical direction with the nose of the face of the photographed person object in the photographed preview image as the center, and at least one face region is obtained.

In one example, referring to fig. 2, a nose 211 of a face 210 of a photographed person object in a preview image may be taken as a center, and the face may be divided in a horizontal direction (i.e., an x-direction in fig. 2) and a vertical direction (i.e., a y-direction in fig. 2) to obtain at least one face region.

Correspondingly, the first beauty parameters can be beauty parameters corresponding to each face area, and specifically can be parameters related to forehead, eye distance, nose augmentation, chin, face thinning and the like.

In the embodiment of the application, the nose of the face of the shot person object in the shot preview image is taken as the center, the face is divided along the horizontal direction and the vertical direction, so that at least one face area can be accurately obtained, and further when the face beautifying parameters of the face are adjusted, the face beautifying parameters of the face areas can be synchronously coordinated according to the areas, so that the face beautifying parameters of the face areas are coordinated and matched, the requirement of a user on the face beautifying effect is met, and the user experience is improved.

In some embodiments of the present application, for a clearer understanding of the technical solutions of the present application, how to adjust the beauty parameters is described in detail below by specific examples for two different situations of the target object:

In the case that the target object is the face of the photographed person object in the photographed preview image, referring to fig. 5, fig. 5 is another implementation manner of the method for adjusting the beauty parameters according to the embodiment of the present application, as shown in fig. 5, the method for adjusting the beauty parameters may include steps 510 to 540.

Step 510, obtaining a first beauty parameter of the face of the photographed person object under the first gesture information.

In some embodiments of the present application, the acquiring a first face-beautifying parameter of the face of the photographed person object under the first pose information may be acquiring a face-beautifying parameter of the face of the photographed person object under the head-up state.

Step 520, second pose information of the face of the photographed person object is detected.

In some embodiments of the present application, the pitch pose of the face and the corresponding pitch angle are obtained by face detection when the camera is in the photographing preview mode, as shown in fig. 3 above.

Step 530, dividing the face into at least one face region with the nose of the face as the center.

Specifically, the face may be divided by referring to the division manner shown in fig. 2 in the above embodiment to obtain at least one face area.

And step 540, adjusting the first beauty parameters according to the first posture information and the second posture information to obtain target beauty parameters corresponding to the second posture information.

In some embodiments of the present application, the first face-beautifying parameters may include a face-positive parameter, a face-side parameter, a face-upper parameter, and a face-lower parameter. The forehead shrinkage in the specific first beauty parameters can belong to the upper parameters of the face, and the chin shrinkage belongs to the lower parameters of the face. The thin face and the eye distance belong to the positive face parameter, and the hump nose belongs to the lateral face parameter.

Specifically, when the head is lifted, the distance between the forehead and the mobile phone camera is increased, the forehead can be reduced in imaging, the distance between the chin and the mobile phone camera is reduced, if the parameters of the forehead contraction and the chin contraction are unchanged, the forehead can be very small, the chin can be very large, and the proportion is easy to be out of order, so that the parameters of the forehead contraction and the chin contraction are required to be reduced, and the proportion coordination is ensured; similarly, when the head is low, the parameters of the forehead contraction and the chin contraction are required to be increased; when the user faces sideways, the forehead and the chin are changed consistently, so that adjustment is not needed.

When the face is sideways, the imaging area of the face is reduced, the area of the face is increased, the interference of the face parameter, such as the reduction of the face thinning parameter, is required to be reduced in order to ensure the proportion coordination, the outline of the face is prevented from being narrowed due to the fact that the face is acted on the face, and the eye distance is also reduced when the face is sideways, so that the parameter of the eye distance is required to be reduced; the nose is of increasing importance when facing sideways, and the nose augmentation parameters need to be increased so that the nose is more stereoscopic.

The beauty parameters such as eye-distance can be adjusted for low head, head lifting and side face. When the head is lifted, eyes are far away from the camera, and the eye-expanding distance needs to be reduced; the lower head is close to the camera, and the eye-expanding distance needs to be increased. For example, if the face is thin, the head is lifted away from the camera, and the face thinning parameters need to be reduced; the low head face is close to the camera, and the face thinning parameter needs to be increased.

In addition to the adjustment of the side face, some side face beautifying items also need to be adjusted when the head is lifted, such as nose augmentation. After head-up, the nose height is more important, and nose augmentation parameters need to be increased, so that the nose is more stereoscopic.

In this way, for different gesture change types and change angles, different beauty treatment Yan Canshu (i.e. front face parameter, side face parameter, face upper parameter or face lower parameter) can be adjusted, as shown in fig. 6 and 7, wherein fig. 6 is a horizontal direction adjustment of the beauty treatment parameter, fig. 7 is a vertical direction adjustment of the beauty treatment parameter, and the pitch angle in fig. 6 and 7 is 3 ° only one example of the present application, and does not represent that only 3 ° is used as an adjustment basis in the present application.

In some embodiments of the present application, after the adjustment is completed, the final beauty Yan Canshu (target beauty parameter) is transferred to the beauty Yan Suanfa, and the face angle continues to be detected.

Therefore, the beauty Yan Canshu (first beauty parameter) is dynamically adjusted by judging the current face pitching angle of the user, and the purpose of quickly adjusting the beauty parameters to the optimal effect is achieved. According to the pitching angle, the side face degree and the like of the face of the user and the mobile phone screen, various parameter values (namely first beautifying parameters of various face areas) of the beauty are changed in real time, the purpose of dynamic adjustment is achieved, and the defect that the beauty effect is quite different due to the rotation of the head of the user is overcome.

(2) The target object being an electronic device

In the case that the target object is an electronic device, referring to fig. 8, fig. 8 is another implementation manner of the method for adjusting a beauty parameter according to the embodiment of the present application, as shown in fig. 8, the method for adjusting a beauty parameter may include steps 810-840.

Step 810, acquiring first gesture information of the electronic device entering the camera for the first time and first beauty parameters under the first gesture information.

In some embodiments of the present application, the first pose information of the electronic device entering the camera for the first time and the first face-beautifying parameter under the first pose information may be data of a gyroscope when the electronic device enters the camera for the first time and face-beautifying parameters under the camera for the first time are obtained.

Step 820, detecting second gesture information of the electronic device.

In some embodiments of the present application, by comparing the current gyroscope data with the gyroscope data in step 810, the position change of the electronic device relative to the face (as shown in fig. 4 above) and the change angle and change type of the electronic device can be calculated when the camera is in the shooting preview mode.

Step 830, dividing the face into at least one face region centered on the nose of the face.

And 840, adjusting the first beauty parameters according to the first posture information and the second posture information to obtain target beauty parameters corresponding to the second posture information.

In some embodiments of the present application, for the case that the target object is an electronic device, the set of beauty parameter adjustment coefficients may be an array, for example [ a1, a2, a3], the second variation type may include upward movement, downward movement and translation of the electronic device, then a1 may be a beauty parameter adjustment coefficient corresponding to the upward movement type of the electronic device, a2 may be a beauty parameter adjustment coefficient corresponding to the downward movement type of the electronic device, and a3 may be a beauty parameter adjustment coefficient corresponding to the translation type of the electronic device.

In some embodiments of the present application, the downward movement of the mobile phone is equivalent to the head raising of a person, the upward movement of the mobile phone is equivalent to the head lowering of a person, and the translation of the mobile phone is equivalent to the side face, so that the specific implementation manner of the embodiments of the present application is consistent with the dynamic adjustment manner of the head raising, the head lowering, and the side face of the person in the shooting preview image for the target object, which is not described here again.

In this way, for different gesture change types and change angles of the electronic device, different adjustments may be performed on the first beauty parameter, as shown in fig. 9 and fig. 10, where fig. 9 is a horizontal direction adjustment of the beauty parameter, fig. 10 is a vertical direction adjustment of the beauty parameter, and the movement angle of the electronic device in fig. 9 and fig. 10 is 3 ° only one example of the present application, and does not represent that only 3 ° is used as an adjustment basis in the present application.
