Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or described herein. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
As in the background art, in the related art, when an image in a posture required by a user is desired, the image can be obtained only by adjusting a photographing posture of the user and performing photographing. Not convenient enough and has higher operation difficulty. In order to solve the problem, an imaging method is provided in the embodiments of the present application, and the imaging method provided in the embodiments of the present application is described in detail with reference to the accompanying drawings through specific embodiments and application scenarios thereof. Referring to fig. 1, fig. 1 is a schematic flowchart of an imaging method provided in an embodiment of the present application. The method comprises the following steps:
s110 identifies first feature information of the first photographic subject in the first photographic preview screen.
The first shooting preview screen is a screen displayed in a preview window of the shooting application. The embodiment of the application is applied to scenes when people are shot. The first photographic subject herein refers to a person.
In the case where a plurality of persons are included in the first shooting preview screen because there is a possibility of shooting by a plurality of persons, optionally, a person satisfying a preset condition may be selected as the first shooting target. The preset conditions herein may include: the maximum ratio in the first shooting preview screen indicates that the person is closest to the lens or the person is at the most prominent position (i.e., C position), and therefore the person is the main shooting object and the posture of the person is adjusted as the first shooting object. Alternatively, the preset conditions may include: the face is opposite to the lens; since many characters are included as backgrounds in the first captured preview screen in some scenes, such as tourist spots, the characters mistakenly entering the first captured preview screen are not always aligned with the shot, and therefore only the character aligned with the shot can be selected for posture adjustment. Alternatively, in other embodiments, other preset conditions may also be set. In addition, when there are a plurality of persons satisfying the preset condition, the subsequent processing may be performed on all of the plurality of persons.
The first characteristic information may include at least one of identity characteristic information, posture information, clothing characteristic information, proportion size in the viewfinder frame, and the like, the identity characteristic information may include age information, sex information, and the like, and the posture information may include a deflection angle of the body and a deflection angle of the head, for example, the head is a front face, that is, the deflection angle is 0 °; the head part turns right to the front side, namely the deflection angle is 90 degrees, and the head part is the back side, namely the deflection angle is 180 degrees; the head part turns to the right side to the left, namely the deflection angle is 270 degrees and the like. The posture information may further include body parts included in the first photographic subject, such as a head, a face, a hindbrain, a neck, four limbs, a back, a chest, a belly, a hall, thighs, calves, feet, and the like. The characteristic information of the clothing may include a type of clothing (e.g., dress, pants), a style of clothing (e.g., boshemian), and the like.
And S120, searching the target posture matched with the first characteristic information from the database.
The database is preset, and contains a plurality of posture images and corresponding feature information, and the construction process of the database will be described in detail later.
The target posture here matches the first feature information of the first photographic subject, and may include at least one of:
the deflection angle of the body in the target posture is smaller than or equal to the deflection angle of the body of the first photographic subject. Since the deflection angle is too large, the posture is usually not good, and therefore, for aesthetic reasons, a target posture with a small deflection angle of the body should be selected.
The yaw angle of the head in the target pose is less than or equal to the yaw angle of the head of the first photographic subject. As above, for aesthetic reasons, a target posture with a small deflection angle of the head should be selected.
The body parts included in the second photographic subject corresponding to the target posture are all included in the first photographic subject. When all body parts included in the target posture are included in the first photographic subject, the posture of the first photographic subject can be sufficiently adjusted, so that the first photographic subject can have a natural effect in the target posture. For example, if the first photographic subject does not include a foot, the second photographic subject corresponding to the target posture cannot include a foot.
Furthermore, in order to ensure the naturalness of the posture adjustment, the matching herein may further include: the second photographic subjects corresponding to the target postures have the same identity characteristic information or clothing characteristic information, for example, the second photographic subjects have the same gender and belong to the same age group, or wear the same type of clothing and the like. The present application does not limit the determination criterion when the determination target posture matches the first feature information.
S130, generating a first target image of the first photographic object in the target posture, in a case where the target posture is found from the database;
and S140, displaying the first target image in a preset display mode.
In the embodiment of the application, first feature information of a first photographic object in a first photographic preview picture can be recognized, then a target posture matched with the first feature information is searched from a preset database, and subsequently the posture of the first photographic object can be adjusted according to the target posture, so that a first target image of the first photographic object in the target posture is obtained. In this case, since the first photographic subject 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, and the photographic difficulty of the user is reduced; and under the condition that the posture is not accurately placed, the image under the ideal posture can be obtained without repeated adjustment, so that the convenience of the user in obtaining the image under the desired posture is improved.
In some embodiments, the S140 may include: the first target image is displayed in the form of a thumbnail.
After the first target image is obtained, the first target image can be displayed in a thumbnail mode, so that a user can conveniently know the posture effect of the first shooting object after the target posture is adjusted.
Optionally, the matching target gestures obtained in the foregoing embodiments may include one or more. The first target images corresponding to the respective target poses may be displayed in the form of thumbnails, respectively. As shown in fig. 2, fig. 2 is a schematic diagram of a thumbnail provided in an embodiment of the present application. The first target image corresponding to the 3 target gestures is included in fig. 2, so that the user can conveniently select the first target image.
In addition, the thumbnail may be specifically displayed within the preview interface where the first shooting preview screen 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 a first input of a target thumbnail from a user;
and responding to the first input, and saving the first target image corresponding to the target thumbnail.
That is, in this embodiment, a user may autonomously select a desired first target image, and since the first target image in the target posture may not meet the requirement of the user, if the first target image is directly saved, a subsequent user further needs to manually delete the first target image, and the storage space of the electronic device is also occupied, in this embodiment, the first target image selected by the user is saved only after receiving the user input, so that the user can directly save the first target image desired by the user, and the convenience of the user is improved. In addition, the user only needs to select the image after the posture adjustment, and the operation difficulty of the user is reduced.
In some embodiments, a gesture assistance control may be provided, such as a button displaying "gesture assistance" within the shooting application interface, and S110 is performed upon receiving a user trigger input to the gesture assistance button. The trigger input here may be a click input to a "gesture assistance" button, or a preset gesture input, or the like.
Due to different scenes, the applicable gestures are different. Therefore, the scene information may also be one of the conditions for the filtering target gesture, that is, the database may further include the scene information corresponding to the gesture image. Also, in other embodiments of the present application, before S130, the method may further include:
identifying scene information in the first shooting preview picture; e.g. indoors, outdoors, or some special scene information, e.g. great wall, palace, etc.
S120 may include:
and searching a target gesture matched with the scene information and the first characteristic information from the database.
That is, in this embodiment, the scene information of the first shooting preview image is identified, and in the subsequent process of selecting the target pose, the target pose needs to be matched with not only the first feature information but also the identified scene information, so that the found target pose more conforms to the current situation of the user, and a better imaging effect is achieved.
In still other embodiments of the present application, the S120 may include:
searching a reference image comprising the target posture from a database;
after S130 and before S140, the method may further include:
if a first ratio of the first object in the first target image is different from a second ratio of the second object corresponding to the target posture in the reference image, the ratio of the first object in the first target image is adjusted according to the second ratio.
In this embodiment, when the ratio of the person in the first target image is greater than or less than the ratio of the person in the reference image, the ratio of the first photographic subject in the first target image is enlarged or reduced so that the first ratio of the first photographic subject in the first target image after adjustment is the same as the second ratio. This way, the first photographic subject can have the same photographic effect as the second photographic subject.
After the proportion of the first shot object in the first target image is amplified, the image resolution of the first shot image in the corresponding first area in the first target image is reduced, the image resolution refers to the number of pixel points in a unit inch, and after the image resolution is reduced, the definition of the first shot object is reduced.
Based on this, optionally, after adjusting the proportion of the first photographic subject in the first target image, the method may further include:
and under the condition that the first image resolution corresponding to the first shooting object is smaller than the second image resolution, adjusting the first image resolution so that the adjusted first image resolution is the same as the second image resolution.
The first image resolution is the image resolution of a first shooting object in a corresponding first area in a first target image; the second image resolution is an image resolution in a region other than the first region within the first target image.
In this embodiment, after the first photographic subject is enlarged, if the first photographic subject is not clear enough, the resolution of the first image of the first photographic subject may be adjusted to reach the resolution of the second image in the other region of the first target image. The resolution of the first image may be adjusted by using an image super-resolution processing algorithm, which is an algorithm capable of amplifying the resolution of the image.
Since a partial blank area, that is, an area originally occupied by the first photographic subject, may appear in the first target image after the ratio of the first photographic subject in the first target image is reduced, in order to ensure the naturalness of the first target image, the partial blank area needs to be filled.
Based on this, optionally, after the ratio of the first photographic subject in the first target image is adjusted, the method may further include:
and in the case that the first target image comprises a blank area, filling the blank area in the first target image with the pre-acquired scene information. The scene information here is the scene information in the recognized first captured 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 natural background effect, and the occurrence of background faults is avoided.
Since the scene information recognized from the first shot preview picture may be recognized when the scene information is occluded by the first shot object, the scene information is not comprehensive enough, and the blank area cannot be completely filled. Based on this, optionally, after the ratio of the first photographic subject in the first target image is adjusted, the method may further include:
under the condition that the scene information does not include background information corresponding to a blank area in the first target image, outputting first prompt information, wherein the first prompt information is used for prompting a user to shoot a background image which does not include a first shooting object;
and filling a blank area in the first target image according to the information in the background image under the condition of acquiring the background image.
In this embodiment, when the blank area cannot be completely filled with the previously acquired scene information, a prompt is given to the user to prompt the user to take a back shot of a pure background image that does not include the first photographic object. Since the pure background image can cover the whole first shooting preview picture, the blank area can be filled based on the background image, and the integrity of the first target image is ensured.
In further embodiments of the present application, the method may further comprise:
under the condition that the target posture is not found from the database, determining a target part which does not accord with preset posture information in each body part of the first shooting object according to the first characteristic information;
and adjusting the posture parameters of the target part according to the preset posture information to obtain a second target image.
In this embodiment, when the matched target pose cannot be found, the target portion that is not enough in the first photographic object is adjusted by using the preset pose information, so that the target portion meets the preset pose information. This makes it possible to adjust the posture of the first subject to have a more elegant posture even if no suitable target posture is found in the database. Here, the preset posture information may include standard posture information of various body parts, such as shoulder, neck, leg, waist, and the like. The adjustment herein refers to optimization of the posture parameters of the target portion based on the preset posture information, for example, adjustment of the shoulder and neck portion from humpback to straight, stretching of the leg portion, and the like.
In order to implement the above embodiment, a database is constructed in advance, and the posture image of the person and the feature information corresponding to the posture image are stored in the database. The database building process may include:
acquiring a figure image;
identifying third characteristic information of the photographic subject in the person image;
and saving the third characteristic information and the person image to a database.
That is, in this embodiment, a person image, such as a star photo or a model photo on the internet, may be selected in advance, and the person image may be acquired by receiving a gesture saving input of the user for the person image, and then acquiring the person image corresponding to the gesture saving input. The gesture save input here may be a trigger input to a "save gesture" key. The person image and the feature information thereof are stored in the database as a posture image. The database is built through the acquired person image, so that the posture can be adjusted subsequently according to the posture image stored in the database, and the convenience of obtaining the image in the desired posture by the user is improved. Alternatively, the person image that has been browsed recently from the internet, for example, the person image that has been browsed in the week, may be automatically downloaded. The user may view in the database.
Optionally, the database may be updated periodically automatically, or may be updated manually by the user, that is, receiving a trigger input of the user to the gesture addition control in the shooting application, for example, a click input to a "+" button, displaying a picture library stored in the electronic device, and then taking the person image selected by the user as the obtained person image and adding the person image to the database.
Further, optionally, after obtaining the second target image, the method may further include:
identifying second characteristic information of the first photographic object in the second target image;
and saving the second characteristic information and the second target image to a database.
That is, in the present embodiment, after the first photographic subject is adjusted according to the standard posture information to obtain the second target image, since the target posture matching the first photographic subject is not included in the database, the posture image included in the database can be perfected by adding the second target image to the database.
In addition, in order to facilitate the user to view the database, the gesture images stored in the database may be classified, for example, according to identity feature information, such as sex, age, and the like, or according to scenes, or according to body parts and clothes features included in the buttons. The application does not define specific sorting criteria.
It should be noted that, in the imaging method provided in the embodiment of the present application, the execution subject may be an imaging apparatus, or a control module in the imaging apparatus for executing a loading imaging method. In the embodiment of the present application, an imaging apparatus executes a loading imaging method as an example, and the imaging method provided in the embodiment of the present application is described.
Based on the above imaging method, an embodiment of the present application further provides an imaging device, as shown in fig. 3, and fig. 3 is a schematic structural diagram of an imaging device provided in an embodiment of the present application. The device includes:

the display module 240 is configured to display the first target image in a preset display manner.
In the embodiment of the application, first feature information of a first photographic object in a first photographic preview picture can be recognized, then a target posture matched with the first feature information is searched from a preset database, and subsequently the posture of the first photographic object can be adjusted according to the target posture, so that a first target image of the first photographic object in the target posture is obtained. In this case, since the first photographic subject 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, and the photographic difficulty of the user is reduced; and under the condition that the posture placement is not accurate enough, the image under the ideal posture can be obtained without repeated adjustment, so that the convenience of the user in obtaining the image under the desired posture is improved.
In some embodiments, the display module 240 is specifically configured to:
the first target image is displayed in the form of a thumbnail.
After the first target image is obtained, the first target image can be displayed in a thumbnail mode, so that a user can conveniently know the posture effect of the first shooting object after the target posture is adjusted.
Optionally, the apparatus may further include:
the first receiving module is used for receiving a first input of a target thumbnail from a user;
and the saving module is used for responding to the first input and saving the first target image corresponding to the target thumbnail.
In the embodiment, the first target image selected by the user is stored only after the user input is received, so that the user can directly store the first target image which the user wants, and the convenience of the user is improved. In addition, the user only needs to select the image after the posture adjustment, and the operation difficulty of the user is reduced.
In another embodiment, gesture lookup module 220 is specifically configured to: a reference image including the target pose is looked up from a database.
The device also includes:
and the proportion adjusting module is used for adjusting the proportion of the first shooting object in the first target image according to the second proportion if the first proportion of the first shooting object in the first target image is different from the second proportion of the second shooting object corresponding to the target posture in the reference image.
In this embodiment, when the ratio of the person in the first target image is greater than or less than the ratio of the person in the reference image, the ratio of the first subject in the first target image is enlarged or reduced so that the first ratio of the adjusted first subject in the first target image is the same as the second ratio. This way, the first photographic subject can have the same photographic effect as the second photographic subject.
Optionally, the apparatus further comprises:
the resolution adjusting module is used for adjusting the resolution of the first image through an image super-resolution processing algorithm under the condition that the resolution of the first image corresponding to the first shooting object is smaller than the resolution of the second image, so that the adjusted resolution of the first image is the same as the resolution of the second image; the first image resolution is the image resolution of a first shooting object in a corresponding first area in a first target image; the second image resolution is an image resolution in a region other than the first region within the first target image.
In this embodiment, after the first photographic subject is enlarged, if the first photographic subject is not clear enough, an image super-resolution processing algorithm may be called to adjust a first image resolution of the first photographic subject, so that the first image resolution may reach a second image resolution of another region in the first target image.
In still other embodiments, the apparatus further comprises:
the scene recognition module is used for recognizing scene information in the first shooting preview picture;
In this embodiment, the scene information of the first shooting preview picture is identified, and in the subsequent process of selecting the target pose, the target pose needs to be matched with not only the first feature information but also the identified scene information, so that the found target pose more conforms to the current situation of the user, and a better imaging effect is achieved.
Optionally, the apparatus further comprises:
the first filling module is used for filling the blank area in the first target image by using the scene information under the condition that the first target image comprises the blank area.
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 natural background effect, and the occurrence of background faults is avoided.
Optionally, the apparatus further comprises:
the prompting module is used for outputting first prompting information under the condition that the scene information does not include background information corresponding to a blank area in the first target image, wherein the first prompting information is used for prompting a user to shoot a background image which does not include a first shooting object;
and the second filling module is used for filling the blank area in the first target image according to the information in the background image under the condition of acquiring the background image.
In this embodiment, when the previously acquired scene information cannot completely fill the blank area, a prompt is given to the user to prompt the user to take a pure background image without the first photographic object, and the background image needs to be in the same background as the previous first photographic preview image, but does not include the first photographic object. Since the pure background image can cover the whole first shooting preview picture, the filling of the blank area can be completed based on the background image, thereby ensuring the integrity of the first target image.
In still other embodiments of the present application, the apparatus further comprises:
the part determining module is used for determining a target part which does not accord with preset posture information in each body part of the first shooting object according to the first characteristic information of the first shooting object under the condition that the target posture is not found in the database;
and the posture adjusting module is used for adjusting the posture parameters of the target part according to the preset posture information to obtain a second target image.

the display unit 306 is configured to display the first target image in a preset display manner.
In the embodiment of the application, first feature information of a first photographic object in a first photographic preview picture can be recognized, then a target posture matched with the first feature information is searched from a preset database, and subsequently the posture of the first photographic object can be adjusted according to the target posture, so that a first target image of the first photographic object in the target posture is obtained. In this case, since the first photographic subject 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, and the photographic difficulty of the user is reduced; and under the condition that the posture is not accurately placed, the image under the ideal posture can be obtained without repeated adjustment, so that the convenience of the user in obtaining the image under the desired posture is improved.
Optionally, the display unit 306 is specifically configured to display the first target image in a thumbnail form.
After the first target image is obtained, the first target image can be displayed in a thumbnail form, so that a user can know how the posture effect of the first shooting object is after the target posture is adjusted.
Optionally, the processor 310 is specifically configured to search a database for a reference image including the target pose;
the processor 310 is further configured to adjust the ratio of the first object in the first target image according to a second ratio if the first ratio of the first object in the first target image is different from the second ratio of the second object corresponding to the target posture in the reference image.
In this embodiment, when the ratio of the person in the first target image is greater than or less than the ratio of the person in the reference image, the ratio of the first photographic subject in the first target image is enlarged or reduced so that the first ratio of the first photographic subject in the first target image after adjustment is the same as the second ratio. This way, the first photographic subject can have approximately the same photographic effect as the second photographic subject.
Optionally, the processor 310 is further configured to, when a first image resolution corresponding to the first shooting object is smaller than the second image resolution, adjust the first image resolution so that the adjusted first image resolution is the same as the second image resolution.
The first image resolution is the image resolution of a first shooting object in a corresponding first area in a first target image; the second image resolution is an image resolution in a region other than the first region within the first target image.
In this embodiment, after the first photographic subject is enlarged, if the first photographic subject is not clear enough, an image super-resolution processing algorithm may be called to adjust the first image resolution of the first photographic subject, so that the first image resolution may reach the second image resolution of other areas in the first target image.
Optionally, the processor 310 is further configured to: identifying scene information in the first shooting preview picture;
the processor 310 is specifically configured to: and searching a target posture matched with the scene information and the first characteristic information of the first shooting object from the database.

the processor 310 is further configured to: and filling a blank area in the first target image according to the information in the background image under the condition of acquiring the background image.
In this embodiment, when the previously acquired scene information cannot completely fill the blank area, a prompt is given to the user to prompt the user to take a pure background image without the first photographic object, and the background image needs to be in the same background as the previous first photographic preview image, but does not include the first photographic object. Since the pure background image can cover the whole first shooting preview picture, the filling of the blank area can be completed based on the background image, thereby ensuring the integrity of the first target image.
Optionally, the processor 310 is further configured to: under the condition that the target posture is not found from the database, determining target parts which do not accord with preset posture information in all body parts of the first shooting object according to the first characteristic information of the first shooting object; and adjusting the posture parameters of the target part according to the preset posture information to obtain a second target image.
In this embodiment, when the matched target pose cannot be found, the target portion that is not enough in the first photographic object is adjusted by using the preset pose information, so that the target portion meets the preset pose information. This makes it possible to adjust the first subject to have a more elegant posture even if no suitable posture is found in the database.
Optionally, the processor 310 is further configured to: identifying second characteristic information of the first photographic object in the second target image; and saving the second characteristic information and the second target image to a database.
In this embodiment, after the first photographic subject is adjusted according to the standard posture information to obtain the second target image, since the database does not include the target posture matching the first photographic subject, the posture image included in the database can be perfected by adding the second target image to the database.
Optionally, the processor 310 is further configured to: acquiring a figure image; identifying third characteristic information of a photographic subject in the person image; and saving the third characteristic information and the person image to a database.
In this embodiment, the database is constructed by the acquired person image, so that the posture can be adjusted subsequently by the posture image stored in the database, and convenience of the user in obtaining the image in the desired posture is improved.
