The image display 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. 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 through 1400, which are described in detail below.
The shooting preview interface is an interface displayed after the shooting application program is entered. Wherein, the shooting object is displayed in the shooting preview interface.
The photographed person can interact with the electronic device based on the set voice, which may be a voice with directivity. For example, the set voice may be "see here", "i am there", or the like.
In this embodiment, before the step 1100 is executed to acquire the voice information of the first voice signal in the case of displaying the shooting preview interface, the shooting method of the present disclosure may further include: in the case of displaying a shooting 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 where the shooting preview interface is displayed, the photographer can click "setup", enter a page for voice entry, and click "start recording voice", and then record the set voice, for example, "see here", "i am there", and the like.
The first voice signal may be a sound emitted from an object displayed in the shooting preview interface, or may be a sound emitted from an object outside the shooting preview interface.
The voice information includes a first sound intensity and source information.
In this embodiment, the first sound intensity of the first voice signal can be determined by detecting the amplitude of the first voice signal.
In this embodiment, a phase difference between first voice signals picked up by two microphones in the electronic device may be obtained first, and the distance and the angle between the two microphones are combined to determine sound source information of the first voice signal.
Example 1, after the electronic device starts to run the photographing application, a photographing preview interface may be displayed on a display screen of the electronic device. In the case of displaying the shooting preview interface, the object displayed in the shooting 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 shooting preview interface, wherein one object shouts "i am there".
When one of the objects in the shooting preview interface calls "i am at this", the electronic device takes "i am at this" as the first voice signal. The sound intensity of the first voice signal "i am here" is determined as the first sound intensity by the amplitude of the first voice signal "i am here". The sound source information of the first voice signal "i am at this" is determined by the phase difference of the first voice signal "i am at this" picked up by the two microphones and combining the distance and the angle between the two microphones. In both the sound source information of the first voice signal corresponding to fig. 3 and fig. 4, the sound source information of the first voice signal indicates that the sound generating 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, the following steps are carried out:
The first zoom magnification is associated with a first sound intensity. It can be known that, in the case where the first voice signal is derived from an object displayed in the shooting preview interface, the auto zoom processing is performed on the preview image in the shooting preview interface according to the first zoom magnification associated with the intensity of the first voice signal.
In an embodiment, before performing zoom processing on the preview image in the captured preview interface according to the first zoom magnification, the first zoom magnification may be determined according to the following steps 2100 to 2200, and then automatic zoom processing is performed on the preview image in the captured preview interface according to the first zoom magnification, in which the capturing method may further include the following steps 2100 to 2200:
in step 2100, in a case where the first sound intensity is less than or equal to a preset intensity threshold, a first preset magnification corresponding to the first sound intensity is determined as a first zoom magnification.
The preset intensity threshold may be a numerical value set according to an actual application scenario and an actual requirement.
In step 2100, first mapping data reflecting mapping relationships 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 can be understood that, in the case that the first sound intensity is less than or equal to the preset intensity threshold, it indicates that the object indicated by the sound source information of the first voice signal is farther from the image pickup device, zoom magnification needs to be performed, that is, zoom magnification needs to be increased. The smaller the first sound intensity is, the higher the zooming magnification of the amplification is, so that the requirement of an actual scene can be met.
Continuing with example 1 in step 1100, if "i am here" in fig. 3 is a sound made by an object displayed in the shooting preview interface, the object is taken as an area that needs zooming, since the intensity of "i am here" is small, it indicates that the object is far away from the image capturing apparatus, at this time, zooming and magnifying the object is needed, and a first preset magnification 5x corresponding to the first sound intensity obtained from the above first mapping data is taken as a first zoom magnification, that is, the current zoom magnification 1x is adjusted to be the first zoom magnification 5 x.
In step 2200, when the first sound intensity is greater than the preset intensity threshold, determining a second preset magnification corresponding to the first sound intensity as the first zoom magnification.
The first preset multiplying power is larger than the second preset multiplying power.
In step 2100, second mapping data reflecting a 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, when the first sound intensity is greater than the preset intensity threshold, indicating that the object indicated by the sound source information of the first voice signal is closer to the image capturing device, zooming-out needs to be performed, that is, zooming-out magnification needs to be adjusted. The zooming magnification of the zooming is higher as the first sound intensity is higher, so that the actual scene requirement can be met.
Continuing with example 1 in step 1100, if "i am here" in fig. 4 is a sound emitted by an object displayed in the shooting preview interface, the object is taken as an area that needs zooming, since the intensity of "i am here" is large, it indicates that the object is closer to the imaging apparatus, at this time, zooming and zooming out of the object are needed, and if a second preset magnification 1x corresponding to the first sound intensity obtained from the above second mapping data is taken as a first zoom magnification, the current zoom magnification 5x is adjusted to be the first zoom magnification 1 x.
In this embodiment, the above performing zoom processing on the preview image in the shooting preview interface according to the first zoom magnification may further include: and executing zooming processing on the preview image in the shooting preview interface by taking 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 shooting preview interface may be automatically zoomed to 5X centering on the object that shouts "i am there" displayed in the shooting preview interface.
As shown in fig. 4, the preview image in the shooting preview interface can be automatically zoomed to 1X centering on the object that shouts "i am there" displayed in the shooting preview interface.
According to the method of the embodiment, when the shooting preview interface is displayed, the first sound intensity and the sound source information of the first voice signal are acquired, and when the sound source information indicates that the sound emitting object of the voice signal is the object displayed in the shooting preview interface, the zooming processing is executed on the preview image in the shooting preview interface through the first zooming magnification associated with the first sound intensity. The method is used for automatically zooming the preview image in the shooting preview interface through the zooming magnification ratio related to the sound intensity of the voice signal of the object displayed in the shooting preview interface, and does not need the user to manually zoom, so that the zooming operation of the user is simplified.
In an embodiment, before performing zoom processing on the preview image in the captured preview interface according to the first zoom magnification, the first zoom magnification may be determined according to the following steps 3100 to 3400, and then automatic zoom processing may be performed on the preview image in the captured preview interface according to the first zoom magnification, in which the capturing method may further include the following steps 3100 to 3400:
step 3100, determining a first intermediate magnification based on a first sound intensity of the first speech signal.
In step 3100, first mapping data and second mapping data are pre-stored in the electronic device, where 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. In general, when the first sound intensity is less than or equal to the preset intensity threshold, a first preset multiplying factor corresponding to the first sound intensity is matched from the first mapping data as a first intermediate multiplying factor. When the first sound intensity is larger than the preset intensity threshold, a second preset multiplying factor corresponding to the first sound intensity is matched from the second mapping data to serve as a first intermediate multiplying factor. The first mapping data and the second mapping data in the embodiment of the present application may be stored in a storage form of a mapping table or other mapping relationships, which is not specifically limited herein.
In step 3100, the first sound intensity may be compared with a preset intensity threshold 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, and the first preset multiplying factor or the second preset multiplying factor is used 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, obtain a second sound intensity of the interference signal in the first voice signal.
It can be understood that in an actual shooting scene, sound sources are often interfered by the outside world. The disturbing signal may be various noise signals such as a whistling sound of a car, a train, etc.
In this step 3200, third mapping data reflecting mapping relationships between different interference signals and 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 obtained first, so as to determine a second sound intensity corresponding to the interference signal according to the amplitude of the interference signal and the third mapping data.
And 3300, determining a second intermediate magnification according to the second sound intensity and the first intermediate magnification. And performs step 3400 or step 3500 as follows.
It will be appreciated that in the presence of interfering signals, the first intermediate magnification will typically be adjusted down. Wherein, the larger the second sound intensity is, the more the first intermediate multiplying power is turned down, and the smaller the obtained second intermediate multiplying power is.
In this step 3300, when it is received that an interfering signal is present in the first audio signal of the object displayed in the shooting preview interface, the first intermediate magnification obtained in the above step 3100 is adjusted to obtain the second intermediate magnification according to the second audio intensity of the interfering signal. Meanwhile, a prompt message 'no zooming operation is performed and voice feedback of a photographer' is displayed on a shooting preview interface.
And step 3400, determining the second intermediate magnification as the first zoom magnification under the condition that the second voice signal of the photographer is not received within the preset time.
In this 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 zoom processing is performed on the preview image in the shooting preview interface according to the target zoom magnification.
Continuing with example 1 of step 3100 above, where 5x is determined as the first intermediate magnification, since the interfering signal is interfering, the first intermediate magnification may be adjusted down to 3x as the second intermediate magnification according to the strength of the interfering signal. Meanwhile, if the voice signal of the photographer is not received within the preset time, the second intermediate magnification ratio 3x is taken as a first zoom magnification ratio, and then the zoom processing is executed on the preview image in the shooting preview interface according to the first zoom magnification ratio.
Continuing with example 1 of step 3100 above, where 1x is determined as the first intermediate magnification, since the interfering signal is interfered, the first intermediate magnification may be adjusted down to 0.8x as the second intermediate magnification according to the strength of the interfering signal. Meanwhile, if the voice signal of the photographer is not received within the preset time, the second intermediate magnification of 0.8x is used as a first zoom magnification, and then the zoom processing is executed on the preview image in the shooting preview interface according to the first zoom magnification.
And 3500, acquiring the target information under the condition of receiving the second voice signal of the photographer within the preset time.
The target information includes at least one of: a third sound intensity of the second speech signal, a keyword in the second speech signal.
In this step 3500, if the second voice signal of the photographer is received within the preset time, the second voice signal of the photographer is recognized to obtain a third sound intensity of the second voice signal and a keyword in the second voice signal, and then a second intermediate magnification is adjusted according to the second sound intensity of the second voice signal and/or the keyword in the second voice signal to obtain a first zoom magnification, and zoom processing 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 "a little bit larger" of the photographer within the preset time, the electronic device increases the second intermediate magnification, for example, increases the second intermediate magnification by 3x to 5x as the first zoom magnification, according to the second voice intensity and/or the keyword "a little bit larger" of the second voice signal, and then performs zoom processing on the preview image in the shooting preview interface according to the first zoom magnification.
According to the embodiment, when the sound emitted by the shooting object is interfered, the expected zoom magnification is provided to execute the zoom processing on the preview image in the shooting preview interface according to the strength of the interference signal, the user does not need to manually execute the zoom, and the zoom operation of the user is simplified. Meanwhile, the expected zooming magnification is adjusted by supporting voice feedback of a user, so that the obtained zooming magnification is more in line with the requirements of the user.
In one embodiment, after the above step 1100 is performed to acquire the voice information of the first voice signal, the photographing method of the embodiment of the present disclosure may further include the following steps 4100 to 4200:
step 4100, when the sound source information indicates that the sound source of the first speech signal is an object outside the imaging preview interface, specifies azimuth information of the sound source based on the sound source information.
In the present embodiment, when the sound source information of the first audio signal indicates that the sound source of the first audio signal is an object outside the imaging preview interface, the direction information of the sound source is determined based on the sound source information of the first audio signal.
Example 2, after the electronic device starts to run the photographing application, a photographing preview interface may be displayed on the display screen of the electronic device. In the case of displaying the shooting preview interface, the photographer may interact with the captured sound by the set voice, as shown in fig. 5, although the object is not displayed in the shooting preview interface, a voice source "i am here" exists outside the shooting preview interface, and at this time, the electronic device may determine the direction information of the sound-emitting object based on the sound source information of "i am here".
Step 4200, outputting a prompt message based on the orientation information.
The prompt message is used for indicating the direction of the shooting device rotated by the photographer so as to enable the sound-producing object to be displayed in the shooting preview interface.
In this embodiment, when the direction information of the sound-generating object is determined, prompt information for instructing a photographer to rotate the direction of the image capturing device is displayed on the display interface of the electronic device, so that the photographer rotates the direction of the image capturing device based on the prompt information, and the sound-generating object is displayed on the shooting preview interface.
Continuing with example 2 of step 4100, as shown in fig. 5, the display interface of the electronic device outputs a prompt message, which includes not only text information of "please turn the mobile phone", but also pointing information pointing to the source "i am there", which is an arrow in fig. 5.
According to the embodiment, prompting and interaction of voice sources other than the shooting preview picture are realized, so that a photographer can be helped to find the object needing to be shot faster in the case that the shooting object is lost.
In one embodiment, before the above step 1100 is performed to acquire the voice information of the first voice signal, the shooting method of the embodiment of the present disclosure may further include the following steps 5100 to 5200:
in step 5100, a fourth speech signal is obtained.
The fourth speech signal comprises sub-speech signals of at least one sound-emitting object.
Example 3, as shown in fig. 6, in the case where the photographing preview interface is displayed, if three objects displayed in the photographing preview interface are simultaneously uttered, the electronic device acquires three sub voice signals, i.e., a sub voice signal 1 of an object 1, a sub voice signal 2 of an object 2, and a sub voice signal 3 of an object 3.
In step 5200, a sub-speech signal of the target utterance object in the fourth speech signal is obtained.
The target sound-emitting object may be an object satisfying a preset condition, and the preset condition includes: the target sound-emitting object is located in a preset area in the shooting preview interface, or the object characteristics of the target sound-emitting object are matched with the preset object characteristics. That is, in the case where the sound of the sound-generating object satisfying the preset condition exists in the fourth speech signal, the sound of the sound-generating object satisfying the preset condition may be determined as the sub-speech signal of the target sound-generating object.
In one example, the preset condition includes that the object feature of the target sound emission object matches with the preset object feature.
The preset object features may be pre-stored face information and attribute information corresponding to each of the remarked face information, and the attribute information 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 the at least one sound-generating object, and at the same time, the electronic device further identifies whether the sub voice information of the target sound-generating object exists in the sub voice signal of the at least one sound-generating object. For example, whether the object features of the sound-generating object are matched with preset object features is firstly identified, and if the object features are matched with the preset object features, the corresponding sound-generating object is taken as a target sound-generating object, and a sub-voice signal of the target sound-generating object is acquired.
Continuing with example 3 of the above step 5100, after the electronic device acquires the three sub-voice signals, the object features of the three sound-emitting objects are matched with the preset object features, and if the object feature of the object 1 in the three sound-emitting objects is successfully matched with the preset object features, the object 1 is taken as the target sound-emitting object, and the sub-voice signal of the object 1 is acquired.
In one example, the preset condition includes that the target sound-emitting object is located in a preset area in the shooting preview interface. The preset area may be a center area of the photographing preview interface.
In this example, in the case of displaying the shooting preview interface, the electronic device acquires a sub voice signal of at least one sound emission object, and at the same time, the electronic device further determines whether there is an object located in a central area of the shooting preview interface in the at least one sound emission object, and if there is an object located in the shooting preview interface, the object is taken as a subject object, i.e., a target sound emission object.
It is understood that the closer the face of the person is to the center area of the photographing preview interface, the greater the possibility of being the subject.
Continuing with example 3 of the above-mentioned step 5100, in the case where the capture preview interface is displayed, the electronic device acquires sub voice signals of at least one sound-emitting object, and at the same time, the electronic device further recognizes whether there is an object located in the center area of the capture preview interface among the three sound-emitting objects, and in the case where the object 1 among the three sound-emitting objects is located in the center area of the capture preview interface, takes the object 1 as a target sound-emitting object, and acquires sub voice signals of the target sound-emitting object.
In step 5300, a sub-speech signal of the target sound emission object is determined as the first speech signal.
Continuing with example 3 of step 5200, after the sub-voice signal of object 1, which is the target sound generation object, is determined, the sub-voice signal of object 1 may be determined as the first voice signal, and then the zoom process may be performed on the preview image in the captured preview interface with object 1 in the captured preview interface as the center according to the first zoom magnification associated with the first sound intensity of the first voice signal.
According to the embodiment, when a plurality of objects in the shooting preview screen simultaneously make sounds, the sounds made by the target sound-making object, which is the main object in the shooting preview screen, are determined, so that the preview image in the shooting preview interface can be zoomed by taking the target sound-making object as the center.
In one embodiment, after the above step 1100 is executed to acquire the voice information of the first voice signal, the shooting method of the embodiment of the present disclosure may further include the following steps 6100 to 6200:
step 6100, obtain a third speech signal.
The third speech signal comprises M sub-speech signals of M sound-emitting 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 sounded, wherein object 1 and object 2 are displayed in the photographing preview interface and object 2 is located outside the photographing preview screen. The electronic device acquires three sub-voice signals, i.e., sub-voice signal 1 of object 1, sub-voice signal 2 of object 2, and sub-voice signal 3 of object 3.
In step 6200, at least one sub voice signal of the M sub voice signals is determined as a first voice signal according to the priority of each sub voice signal.
In this step 6200, at least one sub-voice signal may be obtained from the M sub-voice signals according to the descending order of the priority of each sub-voice signal, and determined as the first voice signal.
In this step 6200, in the case of obtaining M sub-voice signals, the priorities of the M sub-voice signals may be sorted from large to small to obtain a descending sort order of each sub-voice signal, where the sort principle is as follows: the priority of photographing the sub voice signal of the object in the preview interface is greater than the priority of photographing the sub voice signal outside the preview interface. The priority of the sub voice signal having a large sound intensity is higher than that of the sub voice signal having a small sound intensity. The priority of the sub voice signal closer to the preset area in the shooting preview picture interface is greater than the priority of the sub voice signal farther from the preset area in the shooting preview picture interface. The preset area may be a central area of the photographing preview interface.
In one example, the sub-voice signal with the highest priority may be directly selected to be determined as the first voice signal based on the descending order of the priority of each sub-voice 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 objects displayed in the shooting preview interface, and sub-voice signal 3 is a voice signal sent by objects other than the shooting preview interface. The priority of the sub voice signal 1 and the priority of the sub voice signal 2 are higher than the priority of the sub voice 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. Here, the sub voice signal 1 may be directly selected as the first voice signal.
In one example, the sub-voice signals having the priorities of the first and second may be selected as the first voice signal based on the descending order of the priorities of each of the sub-voice signals.
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 objects displayed in the shooting preview interface, and sub-voice signal 3 is a voice signal sent by objects other than the shooting preview interface. The priority of the sub voice signal 1 and the priority of the sub voice signal 2 are higher than the priority of the sub voice signal 3, the sub voice signal 1 and the sub voice signal 2 are selected as the first voice signal.
It is understood that, in the case where the sub voice signal 1 and the sub voice signal 2 can be selected as the first voice signal at the same time, it may be that the zoom magnification 1 associated with the sound intensity of the sub voice signal 1 is acquired, and the zoom magnification 2 associated with the sound intensity of the sub voice signal 2 is acquired. Meanwhile, the zoom magnification ratio 1 and the zoom magnification ratio 2 are compared, if the zoom magnification ratio 1 and the zoom magnification ratio 2 are close, the zoom magnification ratio 1 and the zoom magnification ratio 2 are fused to obtain a fusion magnification ratio, the fusion magnification ratio is used as a first zoom magnification ratio, and then a zoom operation is performed on the preview image in the shooting preview interface according to the first zoom magnification ratio, for example, a zoom process is performed on the preview image in the shooting preview interface with the object 1 and the object 2 as centers.
If the zoom magnification ratio 1 and the zoom magnification ratio 2 are not close, and at this time, as can be seen 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 ratio 1 associated with the sub voice signal 1 is taken as the first zoom magnification ratio, and a zoom operation is performed on the preview image in the shooting preview interface at the first zoom magnification ratio, for example, zoom processing is performed on the preview image in the shooting preview interface with the object 1 as the center.
According to the present embodiment, when a plurality of objects in the shooting preview screen simultaneously make sounds, the object corresponding to the sound with a high priority is zoomed based on the priority ranking of the sounds.
