Detailed ways

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

The terms "first", "second" and the like in the description and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It is to be understood that data so used may be interchanged under appropriate circumstances so that embodiments of the application can be practiced in sequences other than those illustrated or described herein. In addition, "and/or" in the description and claims indicates at least one of the connected objects, and the character "/" generally indicates that the associated objects are in an "or" relationship.

As in the background art, in the related art, if you want to obtain an image in a posture required by a user, it can only be obtained by adjusting the photographing posture of the user and taking a photograph. Inconvenient and difficult to operate. In order to solve this problem, an embodiment of the present application provides an imaging method. The following describes the imaging method provided by the embodiment of the present application in detail through specific embodiments and application scenarios with reference to the accompanying drawings. Referring to FIG. 1 , FIG. 1 is a schematic flowchart of an imaging method provided by an embodiment of the present application. The method includes:

S110: Identify the first feature information of the first shooting object in the first shooting preview screen.

The first shooting preview screen is a screen displayed in the preview window of the shooting application. The embodiments of the present application are applied to a scene when a person is photographed. The first subject here refers to a person.

Wherein, since there is a possibility of multiple people shooting, in the case that the first shooting preview screen includes multiple people, optionally, a person who satisfies a preset condition may be selected as the first shooting object. The preset conditions here may include: the largest proportion in the first shooting preview screen, the largest proportion indicates that the person is closest to the lens or the person occupies the most important position (ie, the C position), so the person is the main shooting object , so it is used as the first subject for posture adjustment. Alternatively, the preset conditions may include: the human face is facing the camera; because in some scenes, such as tourist attractions, the first shot preview image will include many characters as backgrounds, and these characters who enter the first shot preview image by mistake are usually not It will face the camera, so you can select only the person facing the camera for pose adjustment. Or, in other embodiments, other preset conditions may also be set. In addition, in the case where there are multiple characters satisfying the preset condition, subsequent processing may also be performed on all the multiple characters.

Wherein, the first feature information here may include at least one of identity feature information, posture information, clothing feature information, and proportion in the viewfinder frame, etc., and the identity feature information here may include age information, gender information, etc., The posture information can include the deflection angle of the body and the deflection angle of the head. For example, if the head is in the front, the deflection angle is 0°; if the head is turned to the right side, the deflection angle is 90°, and the head is the back, that is, the deflection angle is 90°. 180°; the head is turned to the left side, that is, the deflection angle is 270°, etc. The posture information may also include body parts included in the first photographed object, such as head, face, back of the head, neck, limbs, back, chest, stomach, temple, thigh, calf, foot, and the like. The clothing feature information may include clothing type (eg, dress, trousers) or clothing style (eg, bohemian style).

S120: Search the database for a target pose that matches the first feature information.

The database here is preset, which contains multiple pose images and their corresponding feature information. The construction process of the database will be described in detail later.

The target pose here matches the first feature information of the first photographed object, and may include at least one of the following:

The deflection angle of the body in the target pose is less than or equal to the deflection angle of the body of the first photographing subject. Because the deflection angle is too large, the posture is usually not good-looking, so for aesthetic reasons, a target posture with a small deflection angle of the body should be selected.

The deflection angle of the head in the target pose is less than or equal to the deflection angle of the head of the first photographic subject. As above, for aesthetic reasons, a target pose with a small deflection angle of the head should be chosen.

The body parts included in the second photographing object corresponding to the target pose are all included in the first photographing object. Since the body parts included in the target posture are all included in the first photographing object, sufficient posture adjustment can be performed on the first photographing object, ensuring that the first photographing object can have a relatively natural effect in the target posture. For example, if the first photographed object does not include feet, the second photographed object corresponding to the target pose also cannot include feet.

In addition, in order to ensure the natural degree of posture adjustment, the matching here may also include: the second photographing subject corresponding to the target posture has the same identity feature information or clothing feature information, such as the same gender and belonging to the same age group, or wearing the same types of clothing, etc. The present application does not limit the judgment criteria for judging that the target posture matches the first feature information.

S130, when the target posture is found from the database, generate a first target image of the first photographed subject in the target posture;

S140, displaying the first target image in a preset display mode.

In the embodiment of the present application, the first feature information of the first shooting object in the first shooting preview screen can be identified, and then the target pose matching the first feature information can be searched from a preset database, and then the target pose can be found according to the target The posture of the first photographing subject is adjusted by the posture, so as to obtain a first target image of the first photographing subject in the target posture. In this case, since the first photographed object in the obtained first target image can have the same posture as the target posture, the user does not need to take a specific posture, which reduces the difficulty of photographing for the user; If the positioning is not accurate enough, the image in the ideal posture can be obtained without repeated adjustment, which improves the convenience for the user to obtain the image in the desired posture.

In some embodiments, the above S140 may include: displaying the first target image in the form of a thumbnail.

In this embodiment, after the first target image is obtained, it can be displayed in the form of a thumbnail, which is convenient for the user to understand the posture effect of the first photographed object after the target posture is adjusted.

Optionally, the matched target postures obtained in the foregoing embodiments may include one or more. The first target images corresponding to each target posture may be displayed in the form of thumbnails. As shown in FIG. 2 , FIG. 2 is a schematic diagram of a thumbnail image provided by an embodiment of the present application. FIG. 2 includes the first target images corresponding to the three target poses, so as to facilitate the user's selection.

In addition, the thumbnail image may be specifically displayed in the preview interface where the first shooting preview image is located, as shown in FIG. 2 .

Based on the above embodiment, after displaying the first target image in the form of a thumbnail, the method may further include:

receiving the user's first input on the target thumbnail;

In response to the first input, the first target image corresponding to the target thumbnail is saved.

That is, in this embodiment, the user can independently select a desired first target image. Since the first target image in the target posture may not meet the user's needs, if it is directly saved, the subsequent user needs to manually It will also occupy the storage space of the electronic device. Therefore, in this embodiment, the first target image selected by the user is saved only after the user input is received, so that the user can directly save the first target image he wants. target image to improve user convenience. Moreover, the user only needs to select the image whose posture has been adjusted, which reduces the difficulty of the user's operation.

In some embodiments, a gesture assistance control may be set, for example, a button of "posture assistance" is displayed in the photographing application interface, and S110 is performed again when a trigger input of the gesture assistance button is received from the user. The trigger input here may be a click input on the "posture assist" button, or a preset gesture input, or the like.

Due to different scenarios, the applicable poses are different. Therefore, the scene information can also be used as one of the conditions for screening the target gesture, that is, the database also includes scene information corresponding to the gesture image. Moreover, in other embodiments of the present application, before S130, the method may further include:

Identify scene information in the first shooting preview image; for example, indoors, outdoors, or some special scene information, such as the Great Wall, the Forbidden City, and so on.

S120 can include:

The target pose matching the scene information and the first feature information is searched from the database.

That is, in this embodiment, the scene information of the first shooting preview screen is identified, and in the subsequent process of selecting the target posture, the target posture not only needs to match the first feature information, but also needs to match the identified scene information. , so that the found target pose is more in line with the user's current situation and has better imaging effects.

In still other embodiments of the present application, the foregoing S120 may include:

Find a reference image including the target pose from the database;

After S130 and before S140, the method may further include:

If the first proportion of the first photographed object in the first target image is different from the second proportion of the second photographed object corresponding to the target pose in the reference image, then according to the second proportion, The proportion in the first target image is adjusted.

In this embodiment, when the proportion of people in the first target image is larger or smaller than the proportion of people in the reference image, the proportion of the first shooting object in the first target image is enlarged or reduced, so as to The adjusted first proportion of the first photographed object in the first target image is made the same as the second proportion. In this way, the first photographing subject can have the same photographing effect as the second photographing subject.

Since the proportion of the first photographed object in the first target image is enlarged, the image resolution of the first photographed image in the first area corresponding to the first target image is reduced. The image resolution refers to The number of pixels in a unit inch, after the image resolution is reduced, the clarity of the first object will be reduced.

Based on this, optionally, after adjusting the proportion of the first shooting object in the first target image, the method may further include:

When the resolution of the first image corresponding to the first photographed object is smaller than the resolution of the second image, the resolution of the first image is adjusted so that the adjusted resolution of the first image is the same as the resolution of the second image.

Wherein, the first image resolution is the image resolution of the first shooting object in the first area corresponding to the first target image; the second image resolution is the image resolution in other areas except the first area in the first target image image resolution.

In this embodiment, after zooming in on the first photographed object, if the first photographed object is not clear enough, the first image resolution of the first photographed object can be adjusted so that the first image resolution can reach the first target image The resolution of the second image in other areas in the middle is higher, because the other areas are not enlarged, so the resolution of the second image has a higher resolution. Through this adjustment operation, the clarity of the first photographed object can be guaranteed. The resolution of the first image may be adjusted by using an image super-resolution processing algorithm, which is an algorithm capable of enlarging the image resolution.

Since the proportion of the first object in the first target image is reduced, some blank areas will appear in the first object image, that is, the area originally occupied by the first object. In order to ensure the naturalness of the first object image, This blank area needs to be filled.

Based on this, optionally, after adjusting the proportion of the first shooting object in the first target image, the method may further include:

In the case that the first target image includes a blank area, the blank area in the first target image is filled with the scene information acquired in advance. The scene information here is the identified scene information in the first shooting preview screen.

In this embodiment, the blank area is filled with the scene information in the first shooting preview screen, so that the filled image has a transitional and natural background effect and avoids the occurrence of background faults.

Since the scene information identified in the first shooting preview image may be identified when it is blocked by the first shooting object, this part of the scene information is not comprehensive enough to completely fill the blank area. Based on this, optionally, after adjusting the proportion of the first shooting object in the first target image, the method may further include:

In the case that the scene information does not include the background information corresponding to the blank area in the first target image, output first prompt information, where the first prompt information is used to prompt the user to shoot the background image that does not include the first shooting object;

When the background image is acquired, fill the blank area in the first target image according to the information in the background image.

In this embodiment, when the previously acquired scene information cannot completely fill the blank area, the user will be prompted to take another pure background image that does not include the first shooting object. Of course, the background image needs to be the same as the previous A shot preview image is in the same background, except that the first shot object is not included. Since the pure background image can cover the entire first shooting preview image, the blank area can be filled based on the background image, thereby ensuring the integrity of the first target image.

In still other embodiments of the present application, the method may further include:

In the case where the target posture is not found in the database, according to the first feature information, determine the target body parts that do not conform to the preset posture information among the body parts of the first shooting subject;

According to the preset posture information, the posture parameters of the target part are adjusted to obtain a second target image.

In this embodiment, when a matching target posture cannot be found, the pre-set posture information is used to adjust the substandard target parts in the first photographing object so as to satisfy the pre-set posture information. In this way, even if no suitable target posture is found in the database, the posture of the first photographed subject can be adjusted so that it has a more elegant posture. Wherein, the preset posture information here may include standard posture information of various body parts, such as shoulders, necks, legs, waist and so on. The adjustment here refers to optimizing the posture parameters of the target part according to the preset posture information, for example, adjusting the shoulder and neck position from a hunchback to a straight one, and lengthening the legs.

In order to implement the above embodiment, a database needs to be constructed in advance, and the database stores the pose images of the characters and their corresponding feature information. The database construction process can include:

Get the image of the person;

Recognizing third feature information of the photographed object in the person image;

The third feature information and the person image are saved to the database.

That is, in this embodiment, a person image can be preselected, such as a star photo, a model photo, etc. on the Internet. Here, the way to obtain the person image can be by receiving the user's input for saving the posture of the person image, and then obtaining the corresponding input of the posture saving input. images of people. The gesture saving input here may be a trigger input to the "Save gesture" button. Subsequently, the person image and its characteristic information will be saved in the database as a pose image. The construction of the database is completed by the acquired person images, so that the posture adjustment can be performed subsequently by relying on the posture images saved in the database, and the convenience of obtaining the images in the desired postures by the user is improved. Alternatively, it can also automatically download person images that have been browsed on the Internet recently, for example, person images that have been browsed within a week. Users can view it in the database.

Optionally, the database may be automatically updated periodically, or may be manually updated by the user, that is, receiving a trigger input from the user on the gesture adding control in the shooting application, such as a click input on the "+" button, the electronic device will be displayed. The stored picture library, and then use the character image selected by the user as the obtained character image, and add it to the database.

In addition, optionally, after obtaining the second target image, the method may further include:

identifying the second characteristic information of the first photographed object in the second target image;

The second feature information and the second target image are saved to the database.

That is, in this embodiment, after the first object is adjusted according to the standard posture information and the second target image is obtained, since the database does not contain the target pose matching the first object, the second object image is added to the In the database, the pose images included in the database can be improved.

In addition, in order to facilitate the user to view the database, the posture images saved in the database can be classified, for example, they can be classified according to identity feature information, such as gender, age, etc., or they can also be classified according to the scene, or the body contained in the button.
