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 should be understood that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be implemented 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.
It should be appreciated that reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, the appearances of the phrases "in one embodiment" or "in an embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
In the embodiments of the present application, the term "plurality" means two or more, and other terms are similar thereto.
The shooting method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof. According to the shooting method provided by the embodiment of the application, an execution subject is electronic equipment, and the electronic equipment provided by the embodiment of the application can be terminal equipment with a shooting function, such as a smart phone, a tablet computer, a camera and the like, and can also be other equipment with the shooting function. The following description will be made taking a terminal device as an example.
Fig. 1 is a schematic flowchart of a shooting method provided in an embodiment of the present application, and as shown in fig. 1, the shooting method includes:
when a user opens a photographing function of a camera or other third-party applications on the terminal device, the terminal device enters a photographing mode, and a photographing preview picture can be displayed on a display screen of the terminal device. It can be understood that the shooting preview picture is a preview picture formed by displaying an image collected by the camera on a display screen of the terminal device before the shooting operation is triggered.
The target object is a subject of the photographing operation, and the subject of the photographing operation in the present application is a person, that is, a subject.
And under the condition that a plurality of target objects are included in the shooting preview picture, namely when the current shooting scene is a multi-person group photo scene, the terminal equipment enters an automatic capturing mode.
In an embodiment, the terminal device may perform face detection on the shooting preview picture to obtain the number of faces included in the shooting preview picture, where the number of faces is greater than 1 to indicate that the shooting preview picture includes multiple target objects.
Fig. 2 is a schematic diagram illustrating a terminal device entering an automatic capture mode according to an embodiment of the present disclosure. As shown in fig. 2, a prompt icon for prompting the user that the automatic capture mode is turned on may appear in the photographing preview screen.
And after the terminal equipment enters an automatic capturing mode, acquiring the face characteristics of all target objects. Because the expression of the face is usually dynamically changed, acquiring the face features of all the target objects is also a dynamic operation, and the face features of all the target objects can be obtained by performing face feature recognition on all the target objects uninterruptedly, or by performing face feature recognition on all the target objects at preset intervals, so as to obtain the face features of all the target objects.
The face detection and the face feature recognition belong to image-based face recognition technologies, and the face detection method and the face feature recognition method are not specifically limited in the application.
The facial features include key information of the face, which may also be referred to as facial features or facial features, including position information of the face on the image, key point information of five sense organs, and facial expression information (e.g., whether the eyes are open, smile, whether the eyes are looking at the camera).
It should be noted that the result output by the face feature recognition also includes that the face feature cannot be recognized and/or that the face is incomplete. For example, when the image sharpness is insufficient, the face features cannot be recognized, or the face of the target object does not completely enter the shooting preview screen, the face may be recognized as incomplete.
And the terminal equipment judges whether the face features of each target object meet the shooting triggering conditions or not.
Wherein the shooting trigger conditions include at least two of:
the face is completely recognized;
the face has smile;
the eyes are opened
Binocular emmetropia/focus cameras.
For example, when a certain target subject has a smile on its face and both eyes are open, the terminal apparatus determines that the target subject satisfies the shooting trigger condition.
In the method, if the face features of at least one target object meet shooting triggering conditions, shooting operation is triggered to obtain at least one image.
The method for enabling the face features of at least one target object to meet the shooting triggering conditions comprises the following steps:
the face features of all target objects meet the shooting triggering condition; alternatively, the first and second liquid crystal display panels may be,
the face features of part of the target objects meet the shooting trigger condition.
It is understood that the photographing operation is triggered once whenever the face feature of at least one target object satisfies the photographing trigger condition.
Here, the photographing operation may be an operation in which the terminal device automatically photographs all target objects, may be an operation in which the terminal device automatically photographs the at least one target object, or may be an operation in which the terminal device automatically photographs a plurality of adjacent target objects including the at least one target object. Fig. 3 is a schematic diagram of triggering a shooting operation according to an embodiment of the present application.
102, obtaining a target image according to the at least one image;
the target image comprises a plurality of target objects, and the human face features of the target objects in the target image all meet the shooting trigger condition.
The target image may be an image obtained by one shooting operation, or may be an image obtained by processing images obtained by multiple shooting operations.
It can be understood that, in the case that the face features of all the target objects satisfy the shooting trigger condition, the target image can be obtained by performing one shooting operation. In some embodiments, multiple frames of images may be obtained through multiple shooting operations, and one image with the best imaging effect may be selected from the multiple frames of images as the target image.
For example, when the terminal device starts the automatic capture mode, the camera starts capturing the facial features of all target objects, the key points include that the faces of all target objects can be completely recognized, the eyes of all target objects are opened, the faces of all target objects have smiles, and the eyes of all target objects are looking at the camera, and when the above conditions are met, the shooting operation is automatically triggered. By analogy, as long as the above conditions are met, the terminal equipment performs automatic capturing and snapshot to obtain a multi-frame image, and selects an optimal image as a target image to output. Optionally, the criteria for the best image include the best image parameters, such as proper brightness, best focal length, etc., in addition to the requirement of satisfying the shooting trigger condition.
Optionally, under the condition that the facial features of part of the target objects meet the shooting trigger condition, the target image needs to be obtained through multiple automatic shooting operations, for example, one frame of image is obtained every time of automatic shooting, multiple frames of images are obtained through multiple automatic shooting, the target object images meeting the shooting trigger condition in each frame of image are extracted and synthesized, and the target image is obtained.
In the embodiment of the application, by acquiring the face characteristics of all target objects in the shooting preview picture, the terminal device automatically shoots to obtain at least one image under the condition that the face characteristics of at least one target object meet the shooting trigger condition, and the target image is obtained according to the at least one image, so that each target object can have at least one optimal piece, the picture which is difficult to shoot manually can be captured for a user, the user is not required to obtain the target image by manually shooting modes such as clicking a shooting key on a display screen of the terminal device or other preset shooting keys, and the piece forming efficiency and quality in a multi-person group-photo scene are improved.

it can be understood that when the face features of some target objects satisfy the shooting trigger condition, that is, when there is at least one face feature of a target object that does not satisfy the shooting trigger condition, the target image needs to be obtained through multiple automatic shooting operations.
Optionally, when the terminal device determines that the face features of part of the target objects meet the shooting trigger condition based on the face features of all the target objects, the terminal device triggers shooting operations on all the target objects to obtain an initial shot image, that is, first, a frame of image including the target objects meeting the shooting trigger condition is obtained; and then, starting to capture the face characteristics of the target object of which the face characteristics do not meet the shooting trigger condition in the current shooting preview picture, and triggering the shooting operation to obtain a frame of supplementary shooting image when the face characteristics capturing at least one target object meet the shooting trigger condition.

Optionally, on the basis of the foregoing embodiment, the meeting of the facial features of the partial target objects with the shooting trigger condition includes:
the proportion of the number of the target objects with the face characteristics meeting the shooting trigger condition to the total number of the target objects exceeds a preset threshold value;
alternatively, the first and second electrodes may be,
at least one sub-picture of the shooting preview picture meets the shooting trigger condition, wherein the shooting preview picture is divided into a plurality of sub-pictures, and each sub-picture comprises at least one target object.
In one embodiment, the terminal device counts the face features of all the target objects, and if it is determined that the ratio of the number of the target objects with the face features meeting the shooting trigger condition to the total number of the target objects exceeds a preset threshold, for example, more than half of the face features of the target objects meet the shooting trigger condition, the shooting operation is triggered.
Further, the capturing the human face features of the target object whose human face features do not satisfy the shooting trigger condition, and triggering the shooting operation to obtain the supplementary shot image when the captured human face features satisfy the shooting trigger condition, includes:
carrying out face feature capture on target objects which do not meet shooting trigger conditions, and triggering shooting operation under the condition that the face features of at least one target object captured meet the shooting trigger conditions;
and under the condition that the face characteristics of all the target objects meet the shooting triggering condition at least once, finishing the shooting operation to obtain a supplementary shot image.
Fig. 4 is one of schematic diagrams of an initial captured image provided in the embodiment of the present application, and fig. 5 is one of schematic diagrams of a supplementary captured image provided in the embodiment of the present application. As shown in fig. 4, all target objects are automatically photographed first, and a frame of images including the target objects satisfying the photographing trigger condition is obtained; then, as shown in fig. 5, face feature capturing is performed on the remaining target objects that do not satisfy the shooting trigger condition, and in a case where the face feature capturing at least one target object satisfies the shooting trigger condition, a shooting operation is triggered. And by analogy, finishing face feature capture to obtain a supplementary shot image under the condition that the face features of all the target objects meet the shooting triggering condition at least once.
