Based on the electronic device provided above, the present application further provides a viewing angle adjusting method applied to the electronic device.
As shown in fig. 6, fig. 6 is a first flowchart of a method for adjusting an angle of view according to an embodiment of the present application, where the flowchart may include:
101. an initial field angle of the photographing component is acquired.
As described above, the electronic device to which the viewing angle adjustment method provided by the present application is applied includes a retractable display screen and a photographing component.
Wherein the retractable display screen is capable of being extended or retracted. The shooting assembly is configured to collect images 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 a usable electric signal to obtain a digitized image. After the capture component is enabled, the capture scene can be captured in real time at the corresponding field angle. The larger the field angle, and the smaller the field angle, the smaller the field angle. 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, the area is a shooting scene of the shooting component. Further, the retractable display screen is configured to preview images captured by the capture component.
In this embodiment, when the user starts a shooting application such as "camera", the electronic apparatus enters a shooting mode and the electronic apparatus can acquire an initial angle of view of the shooting component.
In the embodiment of the present application, the angle of view of the photographing assembly is positively correlated to the extension degree of the retractable display screen, wherein when the retractable display screen is fully retracted, the angle of view of the photographing assembly is the smallest, and as the retractable display screen is extended, the angle of view of the photographing assembly is larger, and when the retractable display screen is fully extended, the angle of view of the photographing assembly is the largest. Therefore, when the electronic device enters the photographing mode, the electronic device may acquire a current extension degree of the retractable display screen and then determine an initial field angle of the photographing component according to the current extension degree. Subsequently, the electronic device can adjust the field angle of the capture assembly to the initial field angle. The electronic equipment can acquire images of the shooting scene through the shooting assembly adjusted to the initial field angle to obtain preview images. After obtaining the preview image, the electronic device can display the preview image on the retractable display screen. The electronic device may also acquire the initial field of view for subsequent processing.
For example, assuming that the angle of view of the retractable display screen is 20 degrees when fully retracted, then, every 1 mm of extension (calculated as 1 mm less than 1 mm), the angle of view is increased by 10 degrees, and the maximum extension of the retractable display screen is 12 mm, that is, the angle of view of the retractable display screen is 140 degrees when fully extended. Assuming that the retractable display screen is extended by 2 mm when the electronic device enters the photographing mode, the electronic device may determine that the initial angle of view is 40 degrees.
102. And acquiring the telescopic distance of the telescopic display screen.
The telescopic distance refers to a distance which is increased or decreased in a corresponding telescopic direction when the telescopic display screen is extended or contracted. For example, when the retractable display screen extends from the position A1 to the position A2, the retractable distance of the retractable display screen is the distance between the position A1 and the position A2. For another example, when the retractable display screen is retracted from the position A3 to the position A4, the retractable distance of the retractable display screen is the distance between the position A3 and the position A4.
For example, when the user wants to adjust the field angle of the photographing assembly, the user can manually control the retractable display screen to extend or retract, so that the electronic device can obtain the retractable distance of the retractable display screen.
For another example, the user may speak a corresponding voice, and the electronic device may control the retractable display to extend or retract according to the voice, so that the electronic device may obtain the retractable distance of the retractable display. For example, the speech may be "let the computer be in a position close to the center in the preview image", and when the computer is in a position close to the left or right side in the preview image, the electronic device may control the retractable display screen to extend or retract, so that the electronic device may obtain the retractable distance of the retractable display screen.
For another example, the electronic device may automatically control the extension or the contraction of the retractable display screen based on a moving object, so that the electronic device may obtain the telescopic distance of the retractable display screen. For example, when a moving object exists in the shooting scene and the moving direction of the moving object is the same as the extending direction of the retractable display screen, the electronic device may control the retractable display screen to extend. When a moving object exists in the shooting scene and the moving direction of the moving object is the same as the contraction direction of the telescopic display screen, the electronic equipment can control the telescopic display screen to contract.
103. And determining the field angle of the target according to the initial field angle and the telescopic distance.
For example, when the initial angle of view of the shooting component and the telescopic distance of the telescopic display screen are acquired, the electronic device may determine the target angle of view according to the initial angle of view and the telescopic distance.
104. And adjusting the field angle of the shooting assembly from the initial field angle to the target field angle.
For example, after determining the target field angle, the electronic device may adjust the field angle of the capture assembly from the initial field angle to the target field angle.
For example, assuming that the initial field angle is 20 degrees and the target field angle is 120 degrees, the electronic device may increase the field angle of the photographing component from 20 degrees to 120 degrees.
For another example, assuming that the initial field angle is 50 degrees and the target field angle is 20 degrees, the electronic device may decrease the field angle of the photographing component from 50 degrees to 20 degrees.
In the embodiment of the application, the initial field angle of a shooting component is obtained; acquiring the telescopic distance of the telescopic display screen; determining a target field angle according to the initial field angle and the telescopic distance of the shooting assembly; the field angle of the shooting assembly is adjusted to the target field angle from the initial field angle, so that the field angle of the shooting assembly can be adjusted by controlling the telescopic display screen to extend or contract, clicking or sliding on the telescopic display screen by fingers is not needed, and the shielding of the display screen can be avoided.
In some embodiments, adjusting the field of view of the capture assembly from the initial field of view to the target field of view may include:
when the telescopic distance is the extension distance, increasing the field angle of the shooting assembly from the initial field angle to the target field angle;
and when the telescopic distance is the contraction distance, reducing the field angle of the shooting assembly from the initial field angle to the target field angle.
The telescopic distance may include an extension distance and a contraction distance, where when the telescopic display screen extends from the position A1 to the position A2, a distance between the position A1 and the position A2 is the extension distance, and when the telescopic display screen contracts from the position A3 to the position A4, a distance between the position A3 and the position A4 is the contraction distance.
It is understood that the field angle of the photographing component increases with the extension of the retractable display screen and decreases with the contraction of the retractable display screen, and therefore, when the retractable distance is the extended distance, the target field angle determined by the electronic device is greater than the initial field angle, and therefore, when the retractable distance is the extended distance, the electronic device needs to increase the field angle of the photographing component from the initial field angle to the target field angle. When the telescopic distance is the contraction distance, the target angle of view determined by the electronic device is smaller than the initial angle of view, and therefore, when the telescopic distance is the contraction distance, the electronic device needs to narrow the angle of view of the shooting assembly from the initial angle of view to the target angle of view.
In some embodiments, determining a target field of view from the initial field of view and the telescopic distance may include:
(1) Determining an adjusting field angle according to the telescopic distance;
(2) And determining a target field angle according to the initial field angle and the adjusted field angle.
For example, a preset mapping relationship between the distance and the adjustment field angle may be preset. When the telescopic distance is the extension distance, the electronic equipment can determine and adjust the angle of view according to the telescopic distance. And then calculating the sum of the initial field angle and the adjusted field angle of the shooting assembly to obtain the target field angle. When the telescopic distance is the contraction distance, the electronic equipment can determine and adjust the angle of view according to the telescopic distance. And then calculating the difference between the initial field angle and the adjusted field angle of the shooting assembly to obtain the target field angle.
For example, assume that the preset mapping relationship between the distance and the adjusted field angle includes: the target angle of view is determined to be 50 degrees when the initial angle of view is 40 degrees when the extension distance is 1 mm (1 mm is 1 mm in terms of 1 mm both larger than 0 mm and 2 mm or smaller), and the target angle of view is determined to be 30 degrees when the initial angle of view is 50 degrees when the contraction distance is 2 mm (2 mm is 2 mm both larger than 1 mm and 2 mm smaller than or equal to 2 mm).
In some embodiments, after adjusting the field angle of the photographing component from the initial field angle to the target field angle, may further include:
(1) Acquiring an image of a shooting scene through a shooting component adjusted to a target field angle to obtain a preview image;
(2) Displaying the preview image on the scalable display screen.
For example, after adjusting the field angle of the camera module from the initial field angle to the target field angle, the electronic device may perform image acquisition on the captured scene through the camera module adjusted to the target field angle to obtain a preview image. After obtaining the preview image, the electronic device may display the preview image on the retractable display screen, so that the user may determine whether the angle of view of the photographing component is appropriate through the preview image.
For example, as shown in fig. 7, assuming that the retractable display screen of the electronic device with the retractable display screen in the A1 state is retracted from the A1 state to the A2 state, the electronic device may obtain the angle of view of the shooting component when the retractable display screen is in the A1 state, and obtain an initial angle of view; then, the electronic device can obtain the contraction distance of the telescopic display screen from the A1 state to the A2 state; then, the electronic equipment can determine and adjust the field angle according to the contraction distance; then, the electronic equipment can calculate the difference between the initial field angle and the adjusted field angle to obtain a target field angle; then, the electronic device may decrease the field angle of the photographing component from the initial field angle to the target field angle; then, the electronic equipment can acquire images of the shooting scene through the shooting assembly which increases the field angle of the target view to obtain a preview image; finally, the electronic device may display the preview image on the retractable display screen. As can be seen from the figure, the viewing range of the preview image displayed on the retractable display screen in the A1 state is larger than the viewing range of the preview image displayed on the retractable display screen in the A2 state, because the viewing range becomes smaller as the angle of view becomes smaller after the retractable display screen is retracted from the A1 state to the A2 state, that is, the viewing range can be reduced by controlling the retraction of the display screen.
For another example, please continue to refer to fig. 7, assuming that the retractable display screen of the electronic device with the retractable display screen in the A1 state is extended from the A1 state to the A3 state, the electronic device can obtain the angle of view of the camera module when the retractable display screen is in the A1 state, and obtain the initial angle of view; then, the electronic device can acquire the extending distance of the telescopic display screen from the state A1 to the state A3; then, the electronic equipment can determine and adjust the field angle according to the stretching distance; then, the electronic equipment can calculate the sum of the initial field angle and the adjusted field angle to obtain a target field angle; then, the electronic device can increase the field angle of the shooting component from the initial field angle to the target field angle; then, the electronic equipment can acquire images of the shooting scene through the shooting assembly which increases the field angle of the target view to obtain a preview image; finally, the electronic device may display the preview image on the retractable display screen. As can be seen from the figure, the viewing range of the preview image displayed on the retractable display screen in the A1 state is smaller than that of the preview image displayed on the retractable display screen in the A3 state, because the viewing range becomes large as the angle of view becomes large after the retractable display screen is extended from the A1 state to the A3 state, that is, the viewing range can be increased by controlling the display screen extension.
In some embodiments, before obtaining the telescopic distance of the telescopic display screen, the method may further include:
(1) Determining a target object in a shooting scene of a shooting component;
(2) Acquiring motion data of a target object;
(3) And controlling the display screen to extend or contract according to the motion data.
In this embodiment, the electronic device first determines a target object from a shooting scene of the shooting component according to the configured object determination policy. 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 performs portrait shooting, the user usually focuses on a person in a shooting scene. Thus, the object determination policy may be configured to be: and identifying an object of interest to the user in the shooting scene, and determining the object of interest to the user as a target object. The method for recognizing the object of interest of the user is not particularly limited, and a person skilled in the art may configure a suitable recognition mode 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 accordingly, an object in the salient region is determined as a target object.
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 motion direction and a motion speed. The method for acquiring 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 this embodiment, the electronic device controls the retractable display screen to extend or retract according to the motion data of the target object, so as to drive the shooting component to track the target object. For example, referring to fig. 8, assuming that the determined target object is an illustration person, when it is determined that the person moves to the right according to the movement data of the illustration person, the electronic device correspondingly controls the retractable display screen to extend, so as to increase the field angle of the photographing component, so that the photographing component can photograph the illustration person; when the person moves leftwards according to the movement data of the figure, the electronic device correspondingly controls the telescopic display screen to contract, so that the angle of view of the shooting component is reduced, and the processing load of the processor is reduced on the premise that the shooting component shoots the figure.
In some embodiments, the motion data includes a motion direction and a motion speed of the target object, and controlling the display screen to expand or contract according to the motion data may include:
(1) Determining the target speed of the extension or contraction of the telescopic display screen according to the movement speed;
(2) And controlling the extension or contraction of the telescopic display screen according to the target speed according to the movement direction.
In this embodiment, the extension or contraction of the retractable display screen is controlled according to the moving direction of the target object, and the extension or contraction speed of the retractable display screen is controlled according to the moving speed of the target object.
It should be noted that the orientation of the electronic device when extending or retracting the retractable display screen may vary depending on how the user holds the electronic device. In this embodiment, when the moving direction of the target object matches the direction of the current retractable display screen, it is determined that the screen needs to be extended, and when the moving direction of the target object matches the direction of the position change of the current retractable screen driving shooting component, it is determined that the screen needs to be retracted.
In addition, the electronic equipment determines the expansion and contraction speed corresponding to the movement speed of the target object as the target speed for expanding or contracting the telescopic display screen according to the preset corresponding relation between the movement speed of the target object and the expansion and contraction speed of the telescopic display screen. Accordingly, the electronic device controls the telescopic display screen to extend or retract according to the determined target speed according to the moving direction of the target object.
In some embodiments, determining a target object in a shooting scene of a shooting assembly may include:
in response to the input object specifying instruction, an object specified in the shooting scene by the object specifying instruction is determined as a target object.
In this embodiment, the electronic device passively determines a target object in a shooting scene. The electronic equipment can preview scene images of shooting scenes shot by the shooting assembly in real time through the telescopic display screen, and receives an object designation instruction aiming at the shooting scenes through the telescopic display screen.
For example, the electronic device previews a scene image of a shooting scene shot by the shooting component through the retractable display screen. The shooting scene of the shooting component is a street, including the street itself, a plurality of vehicles (including black cars and blue cars and the like) running on the street, a street tree on one side of the street, and the like. 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 alternative embodiment, determining the target object in the shooting scene of the shooting assembly may include:
(1) Acquiring a gazing area of a current user on a telescopic display screen;
(2) 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 gazes the object of interest in the scene, and therefore, the target object in the shooting scene is determined by using the gazing area of the user in the present embodiment.
The electronic equipment firstly acquires the watching area of the current user on the telescopic display screen.
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 retractable display screen 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.
As above, after acquiring the gazing area of the current user on the scalable display screen, the electronic device further determines an object corresponding to the gazing area in the shooting scene as a target object.
In an optional embodiment, acquiring the current user's gaze area on the retractable display screen may include:
(1) Acquiring a fixation point of a current user on a telescopic display screen;
(2) Acquiring the watching radius of a current user;
(3) And generating a circular watching area of the current user on the telescopic display screen 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 retractable display screen. 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 at the time of gazing is different, and the gazing radius is used in the embodiment of the present application to represent the clear range perceived by the users at the time of gazing. Based on this, for each authorized user of the electronic device (for example, the owner of the electronic device, who authorizes another user who can use the electronic device), in the embodiment of the present application, a gaze radius corresponding to the authorized user is calibrated in advance, and the gaze radius is used to describe a range that can be clearly perceived when the user looks at the gaze. 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 shooting component to obtain a shot image. And then, carrying out face recognition on the obtained shot image to obtain face information of the shot image.
