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 will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. 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.
The shooting method provided by the embodiment of the application can be applied to scenes in which a user uses the electronic equipment to shoot.
For example, for a scene shot by a user using an electronic device, in the related art, the user may often manually switch a lens for a scenario, and take a subject currently speaking as a shooting focus. For example, as shown in fig. 1, in order to provide an operation diagram for a user to capture a video using a mobile phone, a capture lens 1 shown in (a) of fig. 1 includes three capture objects (object a, object B, and object c), and when the object a speaks, the user can adjust the field angle of the camera of the mobile phone by manual zooming on a capture interface to set the object a as a capture object, as shown in (B) of fig. 1, in order to highlight a person. However, the above process requires manual operation by the user, and when the number of times of lens switching is large, the operation is cumbersome and inconvenient.
In view of this problem, in the technical solution provided in this embodiment of the application, when a user uses a mobile phone to perform shooting, the mobile phone collects an audio signal in a current shooting environment in real time, and if it is detected that a certain shooting object makes a sound (for example, it is detected that the object a makes a sound), the direction information of the object a making a sound is determined according to the audio information, and then, based on the direction information, the mobile phone automatically adjusts the orientation and the angle of view of the camera, zooms in and takes the object a as a shooting focus, without any operation performed by the user, thereby greatly reducing the operation steps of the user.
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.
As shown in fig. 2, a shooting method provided in an embodiment of the present application may include the following steps 201 to 204:
step 201, the shooting device collects the audio signal in the current shooting environment.
Illustratively, the shooting device collects audio signals in a shooting environment where the shooting device is currently located in real time through a plurality of microphones arranged on the electronic equipment.
Step 202, the shooting device determines the orientation information of the first object according to the audio signal.
Wherein, the first object is: an object that emits a sound indicated by an audio signal.
For example, after the shooting device acquires the audio signal collected by the microphone, the shooting device analyzes and identifies the audio signal, and if the audio signal contains the sound (including the sounds of speaking, laughing, crying and the like) emitted by a person, the shooting device determines the direction of the shooting object emitting the sound. Specifically, the photographing apparatus may determine a specific orientation of a photographing object from which a sound is emitted, according to a time difference in which the plurality of microphones provided on the electronic device receive the audio signal.
And step 203, the shooting device adjusts the orientation of the camera to the direction corresponding to the orientation information based on the orientation information.
In step 204, the imaging device adjusts the field angle of the camera from a first field angle to a second field angle with the first object as the imaging focus.
The first angle of view is, for example, an angle of view before the camera performs the angle of view adjustment.
It should be noted that, as shown in fig. 3, which is a schematic view of the angle of view of the camera, the light collected by the camera passes through the camera center point 31 and is then projected onto the image sensor 32, and the camera completes image collection. Wherein, the angle A is the visual field angle of the camera, and the angle B is the visual field diameter of the camera. The size of the field of view determines the field of view of the camera, and the larger the field of view, the larger the field of view of the camera. Meanwhile, the field angle of the camera can be adjusted by adjusting the focal length of the camera.
For example, in the embodiment of the present application, the orientation of the camera may be adjusted by using a handheld pan/tilt or a camera with a micro pan/tilt, and further, the camera in the embodiment of the present application is a camera with a micro pan/tilt function, and the orientation of the camera may be adjusted by using the rotation of the micro pan/tilt to adjust the shooting content of the camera.
In the shooting method shown in fig. 1, when the user zooms in to zoom in on the video screen of the object a, the essence of the electronic device that cannot change the orientation of the camera is that the image of the object a is zoomed in by means of digital zooming while the focal length of the camera is increased, and thus the image sharpness is degraded. While for an electronic device that can change the orientation of the camera, the way of enlarging the image of the object a is optical zooming, and in the case of taking the same picture as above, the picture is more clear.
For example, the imaging device automatically adjusts the orientation of the camera to be aligned with the first imaging target after acquiring the orientation information of the first imaging target, and then the imaging device adjusts the angle of view of the camera to bring the first imaging target to the imaging focus of the current lens. It is understood that the above-described shooting focus is a shooting picture in which the first photographic subject is the subject of shooting.
For example, referring to fig. 1, as shown in (a) and (B) of fig. 4, when a user uses a mobile phone to capture a video, if the mobile phone detects that a subject a is speaking, the orientation of the camera is adjusted by the micro-cloud platform, so that the camera is directed to the subject a, and then the angle of view of the camera is adjusted, so that the subject a is the current capture focus.
Therefore, when the electronic equipment shoots, the audio signals in the current shooting environment are collected in real time, if a certain shooting object is detected to make a sound, the azimuth information of the first object is determined according to the audio information, wherein the first object is as follows: an object that emits a sound indicated by an audio signal. Then, based on the orientation information, the orientation of the camera is adjusted to a direction corresponding to the orientation information, and the angle of view of the camera is adjusted from a first angle of view to a second angle of view with the first object as a shooting focus. The electronic equipment can automatically adjust the shooting lens through sound, and the operation steps of manually adjusting the lens by a user are reduced.
Optionally, in this embodiment of the application, after the electronic device automatically adjusts the current shooting lens, a picture shot by the wide-angle lens may be displayed on the shooting preview interface, and a user may click a certain shooting object in the picture, so that the electronic device uses the object as a shooting focus.
After the step 204, the shooting method provided in the embodiment of the present application may further include the following steps 205a1 to 205a 3:
in step 205a1, the image pickup apparatus displays the pickup content at the second field angle in the pickup preview interface, and displays the target window.
The target window and the shooting preview interface are at least partially overlapped, the shooting content displayed in the target window comprises N shooting objects, and N is larger than or equal to 1.
Illustratively, the shooting picture displayed in the target window may be: the wide-angle lens of the electronic equipment shoots pictures.
Step 205a2, the camera receives a first input from a user to a second object in the target window.
Wherein the second object is at least one of the N photographic objects.
In step 205a3, the image capture device switches the content displayed on the capture preview interface to capture content at the third field angle in response to the first input.
And under the third angle of view, the shooting focus of the camera is a second object.
In the embodiment of the present application, before the imaging device changes the imaging target, the orientation of the camera needs to be adjusted so as to be aligned with a new imaging target.
For example, the first input may be: the input of the user on the screen of the electronic device, or the voice instruction input by the user, or the specific gesture input by the user may be determined according to the actual use requirement, and the embodiment of the present invention is not limited. Illustratively, the first input may be a click input of the second object displayed in the target window by the user.
For example, after receiving the second input from the user, the camera identifies the shooting object within the user's click range through image recognition, and then controls the camera to face the shooting object (i.e., the second object) and takes the shooting object as the current shooting focus by adjusting the angle of view.
For example, referring to fig. 4, as shown in fig. 5 (a), a window 51 is displayed in the shooting preview interface of the mobile phone, the window 51 is a shooting preview screen of the wide-angle lens of the mobile phone, and after the user clicks an object c displayed in the window 51, as shown in fig. 5 (B), the mobile phone switches the shooting preview screen in the shooting preview interface to a screen with the object c as a shooting focus.
In this way, the user can switch the shooting focus of the electronic device by clicking any one of the shooting objects in the window displayed in the shooting preview interface.
Optionally, in this embodiment of the application, since the adjustment range of the micro-pan-tilt is limited, when the object emitting sound is not within the adjustment range of the camera, the electronic device may prompt the user to adjust the orientation of the camera by rotating the body.
For example, before the step 203, the shooting method provided in the embodiment of the present application may further include the following steps 203a1 to 203a 3:
in step 203a1, when the first object is not included in the range of the camera, the camera displays a prompt message.
The prompt information is used for indicating a user to adjust the orientation of the camera.
It can be understood that the shooting range of the camera is as follows: in the case where the electronic device remains stationary, the camera can be adjusted toward the maximum range of the shot by the micro-cloud stage.
Illustratively, when the camera is adjusted to the direction through the micro cloud platform and the first object can not be shot, the shooting device displays the prompt message.
In step 203a2, the camera receives a second input from the user to adjust the orientation of the camera.
For example, the second input may be an input for adjusting the orientation of the camera by a user by rotating a body or adjusting the orientation of the electronic device.
In step 203a3, the image capture device adjusts the orientation of the camera from a first orientation to a second orientation in response to the second input.
When the orientation of the camera is a second orientation, the first object is included in the shooting range of the camera.
For example, after the user adjusts the orientation of the camera, the camera may capture the first object. Then, the imaging apparatus recognizes the direction of the first object from the voice according to the methods of step 203 and step 204, and further adjusts the orientation and the angle of view of the second camera so that the first object is the current imaging focus of the first camera.
For example, referring to fig. 4, as shown in fig. 6 (a), when the mobile phone detects that the shooting object c emitting sound is located outside the shooting range of the camera (located on the right side of the shooting range), the user is prompted to "please adjust the lens to the right", and the user turns the mobile phone to the right by turning his body, etc., as shown in fig. 6 (B), so that the object c enters the shooting range of the camera of the mobile phone. Thereafter, as shown in fig. 6 (C), the mobile phone takes the object C as the shooting focus of the current lens in the method shown in fig. 4.
Therefore, when the shooting object which makes sound is located outside the shooting range of the camera, the electronic equipment can display prompt information, and a user can adjust the direction of the camera according to the prompt information, so that the first object enters the shooting range of the camera.
Optionally, in this embodiment of the application, in order to capture a richer scenario, the electronic device may further display a speaking object of a speaking capture object in the capture picture as a capture focus together with the capture object.
After the step 204, the shooting method provided in the embodiment of the present application may further include the following steps 205b1 to 205b 3:
step 205b1, the camera determines the focus of the field of view of the first object.
Wherein the view focus is used to indicate an object at which the first object is gazing. For example, when a first object talks to another object, it is necessary to gaze the other object with eyes, and at this time, the visual field of the first object is focused on the talking object.
Step 205b2, the camera determines the third object the first object gazes at based on the focus of the field of view.
In step 205b3, the camera adjusts the angle of view of the camera from the second angle of view to a fourth angle of view including the first object and the third object.
Illustratively, the camera determines a third object, which is usually a speaking object of the first object, the first object gazes according to the visual field focus of the first object. And then, the field angle of the camera is enlarged, the shooting range of the camera is enlarged, and the third object is made to enter the shooting range of the camera. Meanwhile, the shooting device can also adjust the orientation of the camera so that the first object and the third object are positioned at the center of the shot picture.
Therefore, the electronic equipment can intelligently bring the speaker and the speaking object into the shooting picture at the same time, and the scene sense is increased.
Optionally, in this embodiment of the present application, when the electronic device detects an intention of a user to zoom in or zoom out first, the zoom-in and zoom-out of the lens may be automatically achieved by adjusting the focal length.
After the step 204, the shooting method provided in the embodiment of the present application may further include the following step 205c1, and step 205c2 or step 205c 3:
step 205c1, the shooting device acquires distance information of the relative distance between the camera and the first object;
step 205c2, in the case that the distance information indicates that the relative distance is decreased, the shooting device increases the focal length of the camera;
alternatively, the first and second electrodes may be,
in step 205c3, the camera decreases the focal length of the camera if the distance information indicates that the relative distance is increased.
Illustratively, when the shooting device moves, the shooting device judges the relative position relationship between the current displacement direction of the shooting device and the first object through a position sensor arranged on the electronic equipment. If the current shooting device is far away from the first shooting object, it is determined that the user wants a larger angle of view, so that the shooting range of the camera is larger. On the contrary, when the current shooting device is approaching to the first shooting object, it is determined that the user wants a smaller angle of view, so that the shooting range of the camera becomes smaller, and the shooting main body is highlighted.
For example, under the condition that the scheme is not adopted, the same shooting effect is achieved, the user needs to move 5 steps, according to the method in the scheme, the user only needs to move 2-3 steps to achieve the same shooting effect, and the operation of the user is reduced.
Therefore, after the electronic equipment recognizes the intention of the user to enlarge or reduce the shooting range, the operation steps of the user can be reduced by automatically adjusting the focal length of the camera to enlarge or reduce the shooting range of the camera.
According to the shooting method provided by the embodiment of the application, when a user uses the electronic equipment to shoot, the electronic equipment collects the audio signals in the current shooting environment in real time, if a certain shooting object is detected to make a sound, the direction information of the object making the sound is determined according to the audio information, then based on the direction information, the electronic equipment automatically adjusts the orientation and the angle of view of the camera, the object is used as a shooting focus, the user does not need to perform any operation, and the operation steps of the user are greatly reduced.
