Based on the electronic device provided above, the present application further provides a device control method applied to the electronic device, and as shown in fig. 6, a flow of the device control method provided in the embodiment of the present application may be as follows:
in step 210, a target object in a shooting scene of a shooting component is determined.
As described above, the electronic device to which the device control method provided by the present application is applied includes a screen assembly and a photographing assembly, the screen assembly can be extended or retracted, and the photographing assembly can change position as the screen assembly is extended or retracted.
The shooting assembly is configured to collect an image and at least comprises a lens and an image sensor, wherein the lens is used for projecting an external optical signal to the image sensor, and the image sensor is used for performing photoelectric conversion on the optical signal projected by the lens and converting the optical signal into an available electric signal to obtain a digitized image. After the capture component is enabled, the capture scene can be captured in real-time. A shooting scene is understood to be the real area at which the shooting component is aimed after being enabled, i.e. the area where the shooting component is able to convert the light signal into a corresponding image. For example, after the electronic device enables the shooting component according to the user operation, if the user controls the shooting component of the electronic device to be aligned with an area including a certain object, the area including the object is a shooting scene of the shooting component. Further, the screen component is configured to preview an image captured by the capture component.
In this embodiment, the electronic device first determines an object to be tracked from a shooting scene of the shooting component according to the configured object determination policy, and records the object as a target object. The configuration of the object determination policy is not particularly limited, and may be configured by those skilled in the art according to actual needs.
It is understood that for a photographic scene, various objects may be present, such as people, animals, plants, buildings, and the like. When a user is faced with such a shooting scene, it is not always possible to focus on all objects therein, but only on objects of interest therein. For example, when a user takes a portrait shot, the user usually focuses on a person in the shot scene. Thus, the object determination policy may be configured as: and identifying an object in which the user is interested in the shooting scene, and determining the object in which the user is interested as a target object. The method for identifying the object interested by the user is not particularly limited, and a suitable identification mode may be configured by a person skilled in the art according to actual needs, for example, a shot image of a shooting scene shot by a shooting component may be input into a pre-trained salient region detection model to determine a salient region of the shooting scene, and an object in the salient region is correspondingly determined as a target object.
In step 220, motion data of the target object is acquired.
As above, after determining the target object, the electronic device further obtains motion data of the target object, the motion data describing how the target object moves, including but not limited to at least one of a direction of the movement and a speed of the movement. How to acquire the motion data of the target object is not particularly limited and may be configured by those skilled in the art according to actual needs. For example, the electronic device may analyze and calculate a moving object of the target object according to a position difference between two adjacent frames of images of the target object captured by the capturing component.
In step 230, the screen assembly is controlled to extend or retract according to the motion data of the target object, so as to drive the shooting assembly to track the target object.
In this embodiment, the electronic device controls the screen assembly to extend or retract according to the motion data of the target object, so as to drive the shooting assembly to track the target object. For example, referring to fig. 7, assuming that the determined target object is an illustrated person, when it is determined that the person moves to the right according to the movement data of the illustrated person, the electronic device correspondingly controls the screen component to extend, so as to drive the shooting component to move to the right, thereby realizing the tracking of the illustrated person; when the person moves leftwards according to the movement data of the figure, the electronic equipment correspondingly controls the screen assembly to contract, so that the shooting assembly is driven to move leftwards, and the figure is tracked.
From the above, the electronic device includes a screen assembly and a shooting assembly, the screen assembly can be extended or retracted, and the shooting assembly can change position along with the extension or retraction of the screen assembly. The present application utilizes a screen assembly to drive a camera assembly to track a target object. The method comprises the steps of determining a target object in a shooting scene of a shooting assembly, acquiring motion data of the target object, and correspondingly controlling a screen assembly to extend or contract according to the motion data of the target object so as to drive the shooting assembly to track the target object. Therefore, when tracking shooting is needed, a user does not need to manually adjust a shooting component of the electronic equipment to track the target object, the electronic equipment automatically controls the stretching of the screen component, the shooting component is driven to track the target object, and tracking shooting of the target object can be conveniently achieved.
In an optional embodiment, in order to realize more accurate tracking shooting, the motion data comprises the motion direction and the motion speed of the target object, and the target speed of the expansion or contraction of the screen assembly is determined according to the motion speed; and controlling the screen assembly to extend or retract according to the target speed according to the movement direction.
In this embodiment, the screen assembly is controlled to extend or contract according to the moving direction of the target object, and the speed of extending or contracting the screen assembly is controlled according to the moving speed of the target object.
It should be noted that, depending on the way the user holds the electronic device, the direction of the position change of the shooting component driven when the electronic device extends or retracts the screen component may also be different. In this embodiment, when the moving direction of the target object matches the direction of the change in position of the current screen-stretching driving shooting component, it is determined that the screen needs to be stretched, and when the moving direction of the target object matches the direction of the change in position of the current screen-shrinking driving shooting component, it is determined that the screen needs to be shrunk.
In addition, the electronic equipment determines the stretching speed corresponding to the movement speed of the target object as the target speed for stretching or shrinking the screen assembly according to the preset corresponding relation between the movement speed of the target object and the stretching speed of the screen assembly. Accordingly, the electronic device will control the screen assembly to extend or retract according to the determined target speed according to the moving direction of the target object.
In an alternative embodiment, in response to the input object specifying instruction, an object specified in the shooting scene by the object specifying instruction is determined as the target object.
In this embodiment, the electronic device passively determines a target object in a shooting scene. The electronic equipment can preview a scene image of a shooting scene shot by the shooting component in real time through the screen component, and receives an object specifying instruction aiming at the shooting scene through the screen component.
For example, referring to fig. 8, the electronic device previews a scene image of a shooting scene shot by the shooting component through the screen component. As shown in fig. 8, the shooting scene of the shooting component is a street, including the street itself, a vehicle driving on the street, a street tree on one side of the street, and the like, and assuming that the user desires the electronic device to perform tracking shooting on the object "black car" in the shooting scene, the user can directly click on the "black car" displayed by the screen component, so as to input an object specifying instruction to the electronic device, where the object specifying instruction is used to instruct the electronic device to use the "black car" in the shooting scene as a target object. In response to the object specifying instruction, the electronic apparatus determines an object "black car" in the shooting scene specified by the object specifying instruction as a target object.
In an optional embodiment, a watching area of a current user on a screen component is obtained; and determining the object corresponding to the gazing area in the shooting scene as the target object.
In this embodiment, the electronic device automatically determines the target object in the shooting scene.
It should be noted that, when facing any scene, the user usually subconsciously focuses on the object of interest in the scene, and when shooting, the user also usually performs tracking shooting on the object of interest in the shooting scene. Therefore, the target object in the shooting scene is determined using the user's gaze region in the present embodiment.
The electronic equipment firstly acquires a watching area of a current user on a screen component.
For example, the electronic device may track a gaze point of an eyeball of the current user according to a preconfigured eyeball tracking manner, and then determine a gaze area of the current user on the screen component by using the gaze point. It should be noted that, the eye tracking means that when the human eyes look in different directions, the eyes have slight changes, and these changes can generate extractable features, and the electronic device extracts these features through image capturing or scanning, so as to track the changes of the eyes in real time and obtain their fixation points. The method of tracking the eyeball is not particularly limited, and can be selected by one of ordinary skill in the art according to actual needs. After the gaze point of the eyeball of the current user is tracked, the gaze point is a geometric center, and an area with a preset shape is determined as the gaze area of the current user.
After acquiring the gaze area of the current user on the screen component, the electronic device further determines an object corresponding to the gaze area in the shooting scene as a target object.
In an optional embodiment, a gaze point of a current user at a screen component is obtained; acquiring the gazing radius of a current user; and generating a circular watching area of the current user on the screen assembly according to the watching radius by taking the watching point as an origin.
In this embodiment, the electronic device tracks the gaze point of the eyeball of the current user according to a preconfigured eyeball tracking manner, and accordingly obtains the gaze point of the current user on the screen component. The method of tracking the eyeball is not particularly limited, and can be selected by one of ordinary skill in the art according to actual needs.
It should be noted that the clear range perceived by different users during the gazing process is different, and the gazing radius is used in the embodiment of the present application to represent the clear range perceived by the users during the gazing process. Based on this, for each authorized user of the electronic device (for example, the owner of the electronic device, the owner authorized to use other users of the electronic device), the gaze radius corresponding to the authorized user is calibrated in advance in the embodiment of the present application, and the gaze radius is used to describe the range of clear perception during the gaze of the user. The calibration method of the fixation radius is not specifically limited herein, and a person skilled in the art can select a suitable calibration method according to actual needs. Accordingly, in addition to obtaining the gaze point of the current user, the electronic device also obtains the gaze radius of the current user. For example, the electronic device may perform identity recognition on the current user to obtain identity information of the current user, and then obtain a gazing radius of the current user according to the identity information of the current user.
For example, the electronic device collects face information of authorized users (including owner and other users authorized by owner to use the electronic device) in advance, associates the collected face information with identity information of corresponding authorized users, and stores the face information in a face library. When the watching radius of the current user is obtained, the electronic equipment firstly carries out image shooting through the front camera to obtain a shot image. And then, carrying out face recognition on the obtained shot image to obtain face information of the shot image. And matching the face information obtained by recognition with the face information in the face library, and when the matching is successful, taking the identity information associated with the matched face information in the face library as the identity information of the current user. And finally, the corresponding watching radius can be found according to the identity information of the current user.
After the gaze point of the current user is identified and the gaze radius of the current user is acquired, the electronic device generates a circular area as the gaze area of the current user by taking the gaze point as an origin according to the gaze radius.
In an optional embodiment, the object with the largest overlapping area of the imaging region and the circular gaze region in the shooting scene is determined as the target object.
In this embodiment, the electronic device calculates an overlapping area of an object in which an imaging region overlaps with a circular gaze region of a current user in a shooting scene, and determines an object in which the overlapping area of the imaging region and the circular gaze region is the largest as a target object.
In an optional embodiment, after the screen assembly is controlled to extend or retract according to the motion data so as to drive the shooting assembly to track the target object, the target imaging resolution of the shooting assembly is determined according to the area of the visible area of the screen assembly; adjusting the imaging resolution of the shooting assembly to the target imaging resolution; and previewing an image of the target object captured by the capture component at the target imaging resolution through the viewable area of the screen component.
It should be noted that, in the embodiment, the area of the visible region of the screen assembly changes when the screen assembly is extended or retracted, wherein the area of the visible region of the screen assembly increases when the screen assembly is extended, and the area of the visible region of the screen assembly decreases when the screen assembly is retracted. When the area of the visible region of the screen assembly is changed, the physical resolution that the screen assembly can display is changed. In this embodiment, for promoting the preview effect, carry out dynamic adjustment to the formation of image resolution ratio of shooting the subassembly according to screen pack's flexible to the image that makes the shooting subassembly shoot can be suitable for the preview of screen pack.
The electronic device first obtains the area of the visible area of the screen assembly, determines the display resolution corresponding to the visible area of the screen assembly according to the corresponding relationship between the area of the visible area and the display resolution (which may be configured by those skilled in the art according to actual needs, and is not specifically limited here), and then determines the imaging resolution of the shooting assembly corresponding to the display resolution of the screen assembly as the target imaging resolution of the shooting assembly according to the object relationship between the display resolution and the imaging resolution (which may be configured by those skilled in the art according to actual needs, and is not specifically limited here).
As described above, after the target imaging resolution of the photographing component is determined, the imaging resolution of the photographing component is correspondingly adjusted to the target imaging resolution, and the image of the target object photographed by the photographing component according to the target imaging resolution is previewed through the visible area of the screen component, so that the preview effect of the screen component is improved.
