Detailed ways

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

The terms "first", "second" and the like in the description and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It is to be understood that the data so used are interchangeable under appropriate circumstances so that the embodiments of the present application can be practiced in sequences other than those illustrated or described herein, and distinguish between "first", "second", etc. The objects are usually of one type, and the number of objects is not limited. For example, the first object may be one or more than one. In addition, "and/or" in the description and claims indicates at least one of the connected objects, and the character "/" generally indicates that the associated objects are in an "or" relationship.

The shooting methods provided in the embodiments of the present application can be applied to a scene in which a user uses an electronic device to shoot.

Exemplarily, for a scene where a user uses an electronic device to shoot, in the related art, for the needs of the plot, the user often switches the shots manually, and takes the object currently speaking as the focus of the shooting. For example, as shown in FIG. 1, it is a schematic diagram of the operation of the user using a mobile phone to shoot a video. The shooting lens 1 shown in (A) in FIG. 1 includes three shooting objects (object a, object b and object c). When When object a speaks, in order to highlight the subject, as shown in (B) in Figure 1, the user can adjust the field of view of the camera of the mobile phone through manual zooming on the shooting interface, and then use object a as the subject of shooting. However, the above process requires manual operation by the user, and when the number of lens switching times is large, the operation is cumbersome and inconvenient.

In response to this problem, in the technical solutions provided in the embodiments of the present application, when a user uses a mobile phone to shoot, the mobile phone collects audio signals in the current shooting environment in real time. Object a makes a sound), then according to the audio information, determine the orientation information of the object a that emits the sound, and then, based on the orientation information, the mobile phone automatically adjusts the orientation and field of view of the camera, zooms in on the lens, and takes object a as the focus of shooting , without any operation by the user, which greatly reduces the operation steps of the user.

The shooting methods provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

As shown in Figure 2, a shooting method provided by an embodiment of the present application may include the following steps 201 to 204:

Step 201: The photographing device collects audio signals in the current photographing environment.

Exemplarily, the photographing apparatus collects, in real time, audio signals in a photographing environment where the photographing apparatus is currently located by using multiple microphones provided on the electronic device.

Step 202: The photographing device determines the orientation information of the first object according to the audio signal.

Wherein, the above-mentioned first object is: the object that emits the sound indicated by the audio signal.

Exemplarily, after acquiring the audio signal collected by the microphone, the photographing device analyzes and identifies the audio signal, and if the audio signal contains the sound (including voices such as speech, laughter, crying, etc.) made by a character, it is determined that the audio signal is The orientation of the subject making the sound. Specifically, the photographing apparatus may determine the specific orientation of the photographing object that emits the sound according to the time difference between the multiple microphones provided on the electronic device receiving the audio signal.

Step 203: The photographing device adjusts the orientation of the camera to the direction corresponding to the above-mentioned orientation information based on the above-mentioned orientation information.

Step 204: The photographing device adjusts the angle of view of the camera from the first angle of view to the second angle of view with the first object as the photographing focus.

Exemplarily, the above-mentioned first angle of view is the 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 diagram of the field of view of the camera, the light collected by the camera passes through the center point 31 of the camera and is projected onto the image sensor 32 , and then the camera completes image acquisition. Among them, angle A is the field of view angle of the camera, and B is the diameter of the field of view of the camera. The size of the field of view determines the field of view of the camera. The larger the field of view, the larger the field of view of the camera. At the same time, the field of view of the camera can be adjusted by adjusting the focal length of the camera.

Exemplarily, in this embodiment of the present application, the orientation of the camera can be adjusted through a handheld gimbal or a camera with a micro gimbal. Further, the camera in this embodiment of the present application is a camera with a micro gimbal function. The rotation of the gimbal adjusts the orientation of the camera, and then adjusts the content captured by the camera.

It should be noted that, in the shooting method shown in Figure 1, when the user zooms in on the lens to zoom in on the video image of object a, for electronic devices that cannot change the orientation of the camera, the essence is to increase the focal length of the camera while increasing the focal length of the camera. , the image of object a is enlarged, and the picture clarity will be deteriorated in this way. As for the electronic device that can change the orientation of the camera, the way of magnifying the image of the object a is optical zoom. In the case where the shooting picture is the same as the above-mentioned method, the picture definition is higher in this method.

Exemplarily, after acquiring the orientation information of the first photographing object, the photographing device automatically adjusts the orientation of the camera so that it is aimed at the first photographing object, and then the photographing device adjusts the field of view of the camera to make the first object become The focal point of the current shot. It can be understood that, the above-mentioned photographing focus is a photographing picture in which the first photographing object is used as the photographing subject.

For example, in conjunction with Figure 1, as shown in Figure 4 (A) and (B), when the user uses a mobile phone to shoot a video, if the mobile phone detects that the object a is speaking, the orientation of the camera is adjusted through the micro-cloud platform so that the camera Target object a, and then adjust the field of view of the camera so that object a becomes the current shooting focus.

In this way, when the electronic device is shooting, the audio signal in the current shooting environment is collected in real time, and if it is detected that a certain shooting object emits a sound, the orientation information of the first object is determined according to the audio information, wherein the first object is: An object that emits the sound indicated by the audio signal. Then, based on the azimuth information, the orientation of the camera is adjusted to the direction corresponding to the azimuth information, and the field of view of the camera is adjusted from the first field of view to the second field of view with the first object as the shooting focus. The electronic device can automatically adjust the shooting lens through the sound, thereby reducing the operation steps for the user to manually adjust the lens.

Optionally, in this embodiment of the present application, after the electronic device automatically adjusts the current shooting lens, the screen shot by the wide-angle lens can also be displayed on the shooting preview interface. Make that object the focus of the shot.

Exemplarily, after the above step 204, the photographing method provided by this embodiment of the present application may further include the following steps 205a1 to 205a3:

Step 205a1, the photographing device displays the photographing content under the second angle of view in the photographing preview interface, and displays the target window.

Wherein, the above-mentioned target window and the shooting preview interface at least partially overlap, and the shooting content displayed in the target window includes N shooting objects, and N≥1.

Exemplarily, the shooting picture displayed in the above-mentioned target window may be: a picture taken by a wide-angle lens of an electronic device.

Step 205a2: The photographing apparatus receives a first input from the user to the second object in the target window.

Wherein, the above-mentioned second object is at least one of the N shooting objects.

Step 205a3: In response to the above-mentioned first input, the photographing device switches the content displayed on the photographing preview interface to the photographing content at the third angle of view.

Wherein, under the above-mentioned third angle of view, the shooting focus of the camera is the second object.

It should be noted that, in the embodiment of the present application, before changing the photographing object, the photographing device needs to adjust the orientation of the camera so that it is aimed at the new photographing object.

Exemplarily, the above-mentioned first input may be: the user's input on the screen of the electronic device, or the voice command input by the user, or the specific gesture input by the user, which can be specifically determined according to actual use requirements. Not limited. Exemplarily, the above-mentioned first input may be a user's click input on the second object displayed in the target window.

Exemplarily, after receiving the second input from the user, the photographing device identifies the photographing object within the range of the user's click through image recognition, and then the photographing device controls the camera to face the photographing object (that is, the above-mentioned second object), and adjusts The field of view method takes the subject as the current shooting focus.

For example, in conjunction with 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 the shooting preview screen of the wide-angle lens of the mobile phone. The user clicks the object c displayed in the window 51. Afterwards, as shown in (B) of FIG. 5 , the mobile phone switches the shooting preview screen in the shooting preview interface to a screen with the object c as the shooting focus.

In this way, the user can switch the shooting focus of the electronic device by clicking on any shooting object in the window displayed in the shooting preview interface.

Optionally, in this embodiment of the present application, since the adjustment range of the micro-cloud platform is limited, when the object emitting the 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 turning the body.

Exemplarily, before the above step 203, the photographing method provided in this embodiment of the present application may further include the following steps 203a1 to 203a3:

Step 203a1: In the case that the first object is not included in the photographable range of the camera, the photographing device displays prompt information.

The above prompt information is used to instruct the user to adjust the orientation of the camera.

It can be understood that, the shooting range of the above-mentioned camera is the maximum shooting range that the camera can adjust the orientation of through the micro-cloud platform when the electronic device remains stationary.

Exemplarily, when the above-mentioned camera cannot capture the first object even by adjusting the orientation of the micro-cloud platform, the photographing device displays the above-mentioned prompt information.

Step 203a2: The photographing device receives a second input from the user to adjust the orientation of the camera.

Exemplarily, the second input may be an input for the user to adjust the orientation of the camera by rotating the body or adjusting the orientation of the electronic device.

Step 203a3: In response to the second input, the photographing device adjusts the orientation of the camera from the first orientation to the second orientation.

Wherein, when the orientation of the camera is the second orientation, the photographable range of the camera includes the first object.

Exemplarily, after the user adjusts the orientation of the camera, the camera can capture the above-mentioned first object. Afterwards, the photographing device recognizes the orientation of the first object according to the sound according to the methods of

steps

203 and 204, and further adjusts the orientation and field of view of the second camera, so that the first object becomes the current camera's shooting focus.

For example, in conjunction with Figure 4, as shown in Figure 6 (A), when the mobile phone detects that the object c that emits sound is outside the camera's shooting range (located on the right side of the shooting range), the mobile phone prompts the user "Please right Adjust the lens", the user turns the phone to the right by turning the body, etc., as shown in (B) in Figure 6, so that the object c enters the shooting range of the phone's camera. After that, as shown in (C) of FIG. 6 , the mobile phone uses the object c as the shooting focus of the current lens according to the method shown in FIG. 4 .

In this way, when the sounding object is outside the shooting range of the camera, the electronic device can display prompt information, and the user can adjust the orientation of the camera according to the prompt information, thereby allowing the first object to enter the shooting range of the camera.

Optionally, in this embodiment of the present application, in order to have a richer shooting story, the electronic device may also display the speaking object of the speaking subject and the shooting subject as the shooting focus simultaneously on the shooting screen.

Exemplarily, after the above step 204, the photographing method provided by this embodiment of the present application may further include the following steps 205b1 to 205b3:

Step 205b1, the photographing device determines the focus of the field of view of the first object.

Wherein, the above-mentioned focus of the field of view is used to indicate the object that the first object is looking at. For example, when the first object is talking with other objects, it is necessary to keep an eye on the other object, and at this time, the focus of the first object's field of vision is the talking object.

Step 205b2: The photographing device determines, according to the focus of the field of view, a third object that the first object is looking at.

Step 205b3: The photographing device adjusts the angle of view of the camera from the second angle of view to a fourth angle of view that includes the first object and the third object.

Exemplarily, the photographing device determines the third object that the first object is looking at according to the focus of the field of view of the first object, and generally, the third object is the speaking object of the first object. Afterwards, the field of view of the camera expands the shooting range of the camera, so that the third object enters the shooting range of the camera. At the same time, the photographing device can also adjust the orientation of the camera so that the first object and the third object are located in the center of the photographed picture.

In this way, the electronic device can intelligently incorporate the speaker and the speaking object into the shooting picture at the same time, increasing the sense of presence.

Optionally, in this embodiment of the present application, when the electronic device detects that the user intends to zoom in or zoom out the lens first, it can automatically realize the zooming in and out of the lens by adjusting the focal length.

Exemplarily, after the above step 204, the photographing method provided by this embodiment of the present application may further include the following step 205c1, and step 205c2 or step 205c3:

Step 205c1, the photographing device obtains the distance information of the relative distance between the above-mentioned camera and the above-mentioned first object;

Step 205c2, in the case that the above-mentioned distance information indicates that the relative distance is reduced, the photographing device increases the focal length of the above-mentioned camera;

or,

Step 205c3: In the case that the above-mentioned distance information indicates that the relative distance increases, the photographing device reduces the focal length of the above-mentioned camera.

Exemplarily, when the photographing apparatus moves, the photographing apparatus determines the relative positional relationship between the current displacement direction of the photographing apparatus and the first object through a position sensor provided on the electronic device. If the current shooting device is far away from the first shooting object, it is determined that the user wants a larger field of view to make the shooting range of the camera larger. At this time, the shooting device can automatically reduce the focal length of the camera to increase the viewing angle of the camera. The field angle, which in turn makes the camera's shooting range larger. On the other hand, if the current shooting device is approaching the first object, it is determined that the user wants a smaller field of view, so that the shooting range of the camera is narrowed and the subject is highlighted. At this time, the shooting device can automatically increase the focal length of the camera to Reduce the field of view of the camera, thereby making the shooting range of the camera smaller.

For example, if the above solution is not adopted, to achieve the same shooting effect, the user needs to move 5 steps. According to the method in the above solution, the user only needs to move 2-3 steps to achieve the same shooting effect, reducing the number of users operation.

In this way, after recognizing the user's intention to expand or reduce the shooting range, the electronic device can automatically adjust the focal length of the camera to expand or reduce the shooting range of the camera, thereby reducing the user's operation steps.

In the shooting method provided by the embodiment of the present application, when a user uses an electronic device to shoot, the electronic device collects the audio signal in the current shooting environment in real time, and if it is detected that a certain shooting object emits a sound, it is determined according to the audio information. The orientation information of the object, and then, based on the orientation information, the electronic device automatically adjusts the orientation and field of view of the camera, and uses the object as the focus of shooting, without requiring any operation by the user, which greatly reduces the user's operation steps.
