Technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application are within the scope of the protection of the present application.
The terms first, second and the like in the description and in the claims, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type and not limited to the number of objects, e.g., the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.
The image display method provided by the embodiment of the application is described in detail below by means of specific embodiments and application scenes thereof with reference to the accompanying drawings.
As shown in fig. 1, an embodiment of the present application provides a shooting method, which may be applied to an electronic device, where the electronic device may be a mobile phone, a tablet computer, a notebook computer, or the like. As shown in FIG. 1, the method may include steps 1100-1400, which are described in detail below.
In step 1100, in the case of displaying the photographing preview interface, the voice information of the first voice signal is acquired.
The shooting preview interface is an interface displayed after entering the shooting application program. Wherein, the shooting preview interface displays the shooting object.
The subject may interact with the electronic device based on a set voice, which may be directional. For example, the voice of the setting may be "see here", "i am here", or the like.
In this embodiment, before performing the step 1100 to obtain the voice information of the first voice signal while displaying the shooting preview interface, the shooting method of the present disclosure may further include: in the case of displaying a photographing preview interface, a configuration entry for performing voice configuration is provided, and a voice input through the configuration entry is acquired as a set voice.
As shown in fig. 2, in the case of displaying the shooting preview interface, the photographer may click "set" to enter the page of the voice entry, click "start recording voice", and then record the set voice, for example, "see here", "i am there", and so on.
The first voice signal may be a sound generated by shooting an object displayed in the preview interface, or may be a sound generated by shooting an object outside the preview interface.
The voice information includes first sound intensity and sound source information.
In this embodiment, the first sound intensity of the first voice signal may be determined by detecting the amplitude of the first voice signal.
In this embodiment, the phase difference of the first voice signals picked up by the two microphones in the electronic device may be obtained first, and the distance and the angle between the two microphones are combined to determine the sound source information of the first voice signals.
Example 1, when the electronic device starts running the photographing application, a photographing preview interface may be displayed on a display screen of the electronic device. In the case of displaying the photographing preview interface, the object displayed in the photographing preview interface may interact with the electronic device through the set voice, as shown in fig. 3 and 4, two objects are displayed in the photographing preview interface, and one of the objects shout "i am at this point".
After shooting one of the objects in the preview interface shouting "i am at this", the electronic device takes "i am at this" as the first speech signal. The sound intensity of the first speech signal "i am at this" is determined as the first sound intensity by the amplitude of the first speech signal "i am at this". The phase difference of the first voice signal 'I am at' picked up by the two microphones is combined with the distance and the angle between the two microphones to determine the sound source information of the first voice signal 'I am at'. The sound source information of the first voice signal corresponding to fig. 3 and fig. 4 indicates that the sound object of the first voice signal is an object displayed in the shooting preview interface.
Under the condition that a shooting preview interface is displayed, after voice information of a first voice signal is acquired, entering:
in step 1200, in a case where the sound source information indicates that the sound object of the first voice signal is an object displayed in the photographing preview interface, the zooming process is performed on the preview image in the photographing preview interface at the first zoom magnification.
The first zoom magnification is associated with a first sound intensity. It is known that in the case where the first voice signal originates from the object displayed in the photographing preview interface, it performs an auto-zoom process on the preview image in the photographing preview interface according to the first zoom magnification associated with the intensity of the first voice signal.
In an embodiment, before performing the zooming process on the preview image in the photographing preview interface according to the first zoom magnification, the first zoom magnification may be determined according to the following steps 2100 to 2200, and further, the automatic zooming process may be performed on the preview image in the photographing preview interface according to the first zoom magnification, where the photographing method may further include the following steps 2100 to 2200:
in step 2100, a first preset magnification corresponding to the first sound intensity is determined as a first zoom magnification in the event that the first sound intensity is less than or equal to a preset intensity threshold.
The preset intensity threshold value can be a numerical value set according to an actual application scene and an actual requirement.
In step 2100, first mapping data reflecting the mapping relationship between different first sound intensities and different first preset magnifications is stored in the electronic device in advance, and after the first sound intensity is obtained, the first preset magnifications corresponding to the first sound intensity can be matched from the first mapping data.
It will be appreciated that, in the case where the first sound intensity is less than or equal to the preset intensity threshold, it is indicated that the object indicated by the sound source information of the first voice signal is far from the image capturing apparatus, zoom magnification is required, that is, the zoom magnification is required to be increased. The smaller the first sound intensity is, the higher the zoom magnification is, so that the actual scene requirement can be met.
Continuing with example 1 in step 1100, in fig. 3, when "i am in this" is shooting the sound made by the object displayed in the preview interface, the object is regarded as the area where zooming is required, and since "i am in this" is less intense, it indicates that the object is far away from the image capturing apparatus, at this time, zooming is required to be performed on the object, and the first preset zoom magnification 5x corresponding to the first sound intensity of "i am in this" obtained from the above first mapping data is regarded as the first zoom magnification, that is, the current zoom magnification 1x is increased to the first zoom magnification 5x.
Step 2200, determining a second preset magnification corresponding to the first sound intensity as the first zoom magnification in the case that the first sound intensity is greater than the preset intensity threshold.
The first preset multiplying power is larger than the second preset multiplying power.
In step 2100, second mapping data reflecting the mapping relationship between different first sound intensities and different second preset magnifications is stored in the electronic device in advance, and after the first sound intensity is obtained, the second preset magnifications corresponding to the first sound intensity can be matched from the second mapping data.
It can be understood that, in the case where the first sound intensity is greater than the preset intensity threshold, it is indicated that the object indicated by the sound source information of the first voice signal is closer to the image capturing device, zooming is required, that is, the zoom magnification is required to be reduced. The larger the first sound intensity is, the higher the zoom magnification is, so that the actual scene requirement can be met.
Continuing with example 1 in step 1100, in fig. 4, when "i am in this" is the sound made by the object displayed in the shooting preview interface, the object is regarded as the area where zooming is required, and since "i am in this" is stronger, it indicates that the object is closer to the image capturing apparatus, at this time, zooming is required to be performed on the object, and when the second preset zoom factor 1x corresponding to the first sound intensity of "i am in this" obtained from the above second mapping data is regarded as the first zoom factor, the current zoom factor 5x is reduced to the first zoom factor 1x.
In this embodiment, performing the zooming process on the preview image in the photographing preview interface according to the first zoom magnification may further include: and performing zooming processing on the preview image in the shooting preview interface with the object displayed in the shooting preview interface as a center according to the first zooming magnification.
As shown in fig. 3, the preview image in the photographing preview interface may be automatically zoomed to 5X centering on the object which shouts "i am there" displayed in the photographing preview interface.
As shown in fig. 4, the preview image in the photographing preview interface may be automatically zoomed to 1X centering on the object which shouts "i am there" displayed in the photographing preview interface.
According to the method of the present embodiment, in the case of displaying a shooting preview interface, first sound intensity and sound source information of a first voice signal are acquired, and in the case where the sound source information indicates that a sound-producing object of the voice signal is an object displayed in the shooting preview interface, a zooming process is performed on a preview image in the shooting preview interface by a first zoom magnification associated with the first sound intensity. According to the method, automatic zooming is performed on the preview image in the shooting preview interface through the zooming multiplying power related to the sound intensity of the voice signal of the object displayed in the shooting preview interface, manual zooming is not needed by a user, and zooming operation of the user is simplified.
In an embodiment, before performing the zooming process on the preview image in the shooting preview interface according to the first zoom magnification, the first zoom magnification may be determined according to the following steps 3100 to 3400, and further performing the automatic zooming process on the preview image in the shooting preview interface according to the first zoom magnification, where the shooting method may further include the following steps 3100 to 3400:
step 3100, determining a first intermediate magnification according to a first sound intensity of the first speech signal.
In step 3100, first mapping data and second mapping data are stored in the electronic device in advance, wherein the first mapping data reflects a mapping relationship between different first sound intensities and different first preset magnifications, and the second mapping data reflects a mapping relationship between different first sound intensities and different second preset magnifications. Generally, when the first sound intensity is less than or equal to the preset intensity threshold, a first preset magnification corresponding to the first sound intensity is matched from the first mapping data as a first intermediate magnification. When the first sound intensity is greater than the preset intensity threshold, a second preset multiplying power corresponding to the first sound intensity is matched from the second mapping data to serve as a first intermediate multiplying power. The first mapping data and the second mapping data in the embodiments of the present application may be stored in a mapping table or other storage forms of mapping relationships, which are not limited herein specifically.
In step 3100, the first sound intensity may be compared with a preset intensity threshold, so as to match a first preset multiplying factor or a second preset multiplying factor corresponding to the first sound intensity from the first mapping data or the second mapping data of the first voice signal, as a first intermediate multiplying factor.
Continuing with example 1 of step 2100 above, when the first sound intensity is less than or equal to the preset intensity threshold, a first preset magnification 5x may be determined as a first intermediate magnification according to the first sound intensity of the first speech signal and the first mapping data.
Continuing with example 1 of step 2200 above, when the first sound intensity is greater than the preset intensity threshold, a second preset magnification 1x may be determined as the first intermediate magnification according to the first sound intensity of the first speech signal and the second mapping data.
Step 3200, a second sound intensity of an interfering signal in the first speech signal is obtained.
It will be appreciated that in an actual shooting scene, the sound source tends to be disturbed by the outside world. The interference signal may be various noise signals such as a whistle of an automobile, a train, etc.
In this step 3200, third mapping data reflecting the mapping relationship between the different interference signals and the different second sound intensities is stored in the electronic device in advance. In this step 3200, the amplitude of the interference signal in the first speech signal may be first obtained, so as to determine the second sound intensity corresponding to the interference signal according to the amplitude of the interference signal and the third mapping data.
In step 3300, a second intermediate magnification is determined based on the second sound intensity and the first intermediate magnification. And performs the following step 3400 or step 3500.
It will be appreciated that in the presence of an interfering signal, the first intermediate multiplying power will typically be reduced. The larger the second sound intensity is, the more the first intermediate multiplying power is reduced, and the smaller the second intermediate multiplying power is.
In this step 3300, when an interference signal exists in the first voice signal of the object displayed in the shooting preview interface, the first intermediate magnification obtained in the above step 3100 is adjusted according to the second sound intensity of the interference signal to obtain a second intermediate magnification. Meanwhile, prompt information 'do not zoom operation' is displayed on a shooting preview interface, and voice feedback of a photographer is waited.
In step 3400, in the case that the second voice signal of the photographer is not received within the preset time, the second intermediate magnification is determined as the first zoom magnification.
In step 3400, if the voice signal of the photographer is not received within the preset time, the second intermediate magnification is used as the first zoom magnification, and then the zooming process is performed on the preview image in the shooting preview interface according to the target zoom magnification.
Continuing with example 1 of step 3100, when it is determined that 5x is the first intermediate multiplying power, the first intermediate multiplying power may be reduced to 3x as the second intermediate multiplying power according to the strength of the interference signal at this time because the interference signal is interfered. Meanwhile, if the voice signal of the photographer is not received within the preset time, the second intermediate magnification 3x is used as a first zoom magnification, and then the zooming process is performed on the preview image in the shooting preview interface according to the first zoom magnification.
Continuing with example 1 of step 3100, when it is determined that 1x is the first intermediate multiplying power, the first intermediate multiplying power may be reduced to 0.8x as the second intermediate multiplying power according to the strength of the interference signal at this time because the interference signal is interfered. Meanwhile, if the voice signal of the photographer is not received within the preset time, the second intermediate multiplying power of 0.8x is used as a first zooming multiplying power, and then zooming processing is carried out on the preview image in the shooting preview interface according to the first zooming multiplying power.
Step 3500, obtaining target information when the second voice signal of the photographer is received within the preset time.
The target information includes at least one of: third sound intensity of the second voice signal, keywords in the second voice signal.
In step 3500, if the second voice signal of the photographer is received within the preset time, the second voice signal of the photographer is identified to obtain the third sound intensity of the second voice signal and the keywords in the second voice signal, and further the second intermediate magnification is adjusted according to the second sound intensity of the second voice signal and/or the keywords in the second voice signal to obtain the first zoom magnification, and the zooming process is performed on the preview image in the shooting preview interface based on the first zoom magnification.
Continuing with example 1 of step 3400, if the electronic device receives the second voice signal "big one point" of the photographer within the preset time, the electronic device will increase the second intermediate magnification according to the second voice signal "big one point" and/or the keyword "big", for example, increase the second intermediate magnification 3x to 5x as the first zoom magnification, and then execute the zoom process on the preview image in the shooting preview interface according to the first zoom magnification.
According to the embodiment, under the condition that the sound emitted by the shooting object is interfered, the expected zoom magnification is provided for carrying out zooming processing on the preview image in the shooting preview interface in combination with the intensity of the interference signal, the user is not required to manually carry out zooming, and the zooming operation of the user is simplified. Simultaneously, the expected zoom magnification is adjusted by supporting user voice feedback, so that the obtained zoom magnification meets the user requirement.
In one embodiment, after the above step 1100 is performed to obtain the voice information of the first voice signal, the photographing method of the embodiment of the disclosure may further include the following steps 4100 to 4200:
in step 4100, if the sound source information indicates that the sound emission object of the first speech signal is an object outside the shooting preview interface, azimuth information of the sound emission object is determined based on the sound source information.
In this embodiment, when the sound source information of the first voice signal indicates that the sound generating object of the first voice signal is an object outside the shooting preview interface, the azimuth information of the sound generating object is determined first based on the sound source information of the first voice signal.
Example 2, after the electronic device begins running the photographing application, the photographing preview interface may be displayed on the electronic device display screen. In the case of displaying the shooting preview interface, the shot person may interact through the set voice, as shown in fig. 5, although the object is not displayed in the shooting preview interface, a voice source "i am in this" exists outside the shooting preview interface, and at this time, the electronic device determines the azimuth information of the sounding object based on the sound source information of "i am in this".
Step 4200, outputting a prompt based on the orientation information.
The prompt information is used for indicating the photographer to rotate the direction of the photographing device so that the sounding object is displayed in the photographing preview interface.
In this embodiment, when the azimuth information of the sound object is determined, prompt information for indicating the direction in which the photographer rotates the photographing device is displayed on the display interface of the electronic device, so that the photographer rotates the direction of the photographing device based on the prompt information, and the sound object is displayed on the photographing preview interface.
Continuing with example 2 of step 4100 above, as shown in fig. 5, the display interface of the electronic device outputs a prompt message that includes not only the text message "please turn the mobile phone" but also the pointing message to the voice source "i am there", which is an arrow in fig. 5.
According to the embodiment, the prompt and interaction of the voice source outside the shooting preview picture are realized, so that the photographer can be helped to find the object to be shot more quickly under the condition that the shot object is lost.
In one embodiment, before performing the above step 1100 to obtain the voice information of the first voice signal, the photographing method of the embodiment of the disclosure may further include the following steps 5100 to 5200:
In step 5100, a fourth speech signal is acquired.
The fourth speech signal comprises sub-speech signals of at least one sound object.
In example 3, as shown in fig. 6, in the case of displaying the photographing preview interface, if three objects displayed in the photographing preview interface are simultaneously uttered, the electronic device may acquire three sub-voice signals, namely, sub-voice signal 1 of object 1, sub-voice signal 2 of object 2, and sub-voice signal 3 of object 3.
In step 5200, a sub-speech signal of the target sound object in the fourth speech signal is obtained.
The target sound object may be an object satisfying preset conditions including: the target sound object is located in a preset area in the shooting preview interface, or object characteristics of the target sound object are matched with the preset object characteristics. That is, in the case where there is a sound of a sound emission object satisfying the preset condition in the fourth voice signal, the sound of the sound emission object satisfying the preset condition may be determined as a sub-voice signal of the target sound emission object.
In one example, the preset condition includes that the object features of the target sound object match the preset object features.
The above preset object features may be pre-stored face information, and attribute information corresponding to each of the noted face information, which may include a name and a relationship with a photographer. Here, the photographing method of the present disclosure may further include: and receiving a first input, and responding to the first input to acquire the preset object characteristics.
In this example, in the case of displaying the shooting preview interface, the electronic device may acquire the sub-voice signal of at least one sound object, and at the same time, the electronic device further identifies whether the sub-voice information of the target sound object exists in the sub-voice signal of the at least one sound object. For example, whether the object features of the sound generating object are matched with the preset object features is firstly identified, and when the object features are matched, the corresponding sound generating object is used as a target sound generating object, and a sub-voice signal of the target sound generating object is acquired.
Continuing with example 3 of step 5100, after the electronic device obtains the three sub-voice signals, the object features of the three sound generating objects are matched with the preset object features, and if the object features of the object 1 in the three sound generating objects are successfully matched with the preset object features, the object 1 is taken as the target sound generating object, and the sub-voice signals of the object 1 are obtained.
In one example, the preset condition includes a preset area in the shooting preview interface where the target sound object is located. The preset area may be a center area of the photographing preview interface.
In this example, when the shooting preview interface is displayed, the electronic device may acquire a sub-voice signal of at least one sound generating object, and at the same time, the electronic device further determines whether an object located in a center area of the shooting preview interface exists in the at least one sound generating object, and if the object located in the shooting preview interface exists, the object is taken as a main object, that is, a target sound generating object.
It is understood that the closer to the face of the center area of the photographing preview interface, the greater the likelihood of being the subject.
Continuing with example 3 of step 5100, in the case of displaying the shooting preview interface, the electronic device may acquire a sub-speech signal of at least one sound object, and at the same time, the electronic device further identifies whether there is an object located in a central region of the shooting preview interface among the three sound objects, and in the case that object 1 of the three sound objects is located in a central region of the shooting preview interface, takes object 1 as a target sound object, and acquires a sub-speech signal of the target sound object.
In step 5300, a sub-speech signal of the target speech object is determined as a first speech signal.
Continuing with example 3 of step 5200, after determining the sub-speech signal of the target sound object, i.e., object 1, the sub-speech signal of object 1 may be determined as the first speech signal, and further, the zooming process may be performed on the preview image in the photographing preview interface with respect to the object 1 in the photographing preview interface as a center according to the first zoom magnification associated with the first sound intensity of the first speech signal.
According to the embodiment, when a plurality of objects in the shooting preview screen emit sound at the same time, the sound emitted by the main object, namely the target sound emitting object, in the shooting preview screen is determined, so that the preview image in the shooting preview interface can be zoomed by taking the target sound emitting object as the center.
In one embodiment, after the above step 1100 is performed to obtain the voice information of the first voice signal, the photographing method of the embodiment of the disclosure may further include the following steps 6100 to 6200:
in step 6100, a third voice signal is acquired.
The third speech signal includes M sub-speech signals of M sound objects. M is a positive integer greater than or equal to 2.
Example 4, in the case of displaying the photographing preview interface, if two objects displayed in the photographing preview interface and one object outside the photographing preview interface are simultaneously uttered, wherein object 1 and object 2 are displayed in the photographing preview interface, object 2 is located outside the photographing preview screen. The electronic device will acquire three sub-speech signals, namely sub-speech signal 1 of object 1, sub-speech signal 2 of object 2, and sub-speech signal 3 of object 3.
In step 6200, at least one of the M sub-voice signals is determined as the first voice signal according to the priority of each sub-voice signal.
In step 6200, at least one sub-speech signal may be obtained from the M sub-speech signals according to the descending order of priority of each sub-speech signal and determined as the first speech signal.
In step 6200, when M sub-voice signals are acquired, the priority of the M sub-voice signals may be first sorted from big to small to obtain a descending sorting order of each sub-voice signal, where the sorting principle is as follows: the priority of the sub-voice signals of the object in the shooting preview interface is higher than the priority of the sub-voice signals outside the shooting preview interface. The priority of the sub-speech signal with large sound intensity is higher than the priority of the sub-speech signal with small sound intensity. The priority of the sub-voice signal closer to the preset area in the shooting preview screen interface is greater than the priority of the sub-voice signal farther from the preset area in the shooting preview interface. The preset area may be a center area of the photographing preview interface.
In one example, the highest priority sub-speech signal may be selected directly to be determined as the first speech signal based on the descending order of priority of each sub-speech signal.
Continuing with example 4 of step 6100, the electronic device obtains three sub-voice signals, where sub-voice signal 1 and sub-voice signal 2 are voice signals sent by an object displayed in the shooting preview interface, and sub-voice signal 3 is a voice signal sent by an object outside the shooting preview interface. The priority of sub-speech signal 1 and the priority of sub-speech signal 2 are both higher than the priority of sub-speech signal 3. Meanwhile, since the sound intensity of the sub-voice signal 1 is greater than that of the sub-voice signal 2, the priority of the sub-voice signal 1 is greater than that of the sub-voice signal 2.

Then the priority of sub-speech signal 1 and the priority of sub-speech signal 2 are both higher than the priority of sub-speech signal 3, and sub-speech signal 1 and sub-speech signal 2 are selected as the first speech signal.
It will be appreciated that in the case where the sub-speech signal 1 and the sub-speech signal 2 can be selected as the first speech signal at the same time, it may be that the zoom magnification 1 associated with the sound intensity of the sub-speech signal 1 is acquired, and the zoom magnification 2 associated with the sound intensity of the sub-speech signal 2 is acquired. Meanwhile, the zoom magnification 1 and the zoom magnification 2 are compared, if the zoom magnification 1 and the zoom magnification 2 are close, the zoom magnification 1 and the zoom magnification 2 are fused to obtain a fused magnification, the fused magnification is used as a first zoom magnification, and further, a zooming operation is performed on the preview image in the shooting preview interface according to the first zoom magnification, for example, the zooming process is performed on the preview image in the shooting preview interface by taking the object 1 and the object 2 as the center.
If the zoom magnification 1 and the zoom magnification 2 are not close, at this time, as is known from the above analysis, the priority of the sub-voice signal 1 of the object 1 is higher than the priority of the sub-voice signal 2 of the object 2, the zoom magnification 1 associated with the sub-voice signal 1 is taken as the first zoom magnification, and the zooming operation is performed on the preview image in the photographing preview interface at the first zoom magnification, for example, the zooming process is performed on the preview image in the photographing preview interface centering on the object 1.
