The electronic device generally comprises a camera and a microphone, and when the electronic device takes images through the camera, audio signals need to be acquired through the microphone, so that video shooting of the electronic device is achieved. However, when the electronic device only shoots an image signal in a certain direction through the camera, the microphone simultaneously captures audio signals in all directions, so that the capturing direction of the image signal is different from that of the audio signal, excessive noise is generated, and the video shooting effect is seriously affected.

When the electronic device performs video shooting, the first state and the second state may include: the first state is an on state and the second state is an on state, the first state is an on state and the second state is an off state, and the first state is an off state and the second state is an on state.

In some implementations, the electronic device, after determining a target audio processing parameter from the plurality of audio processing parameters, may process the plurality of audio signals captured by the microphone based on the target audio processing parameter.

As one mode, when the electronic device determines a first audio processing parameter as a target audio processing parameter from the plurality of audio processing parameters, based on the first audio processing parameter, an audio signal of a sound source located on the front side of the electronic device among the plurality of audio signals collected by the microphone may be subjected to enhancement processing, and audio signals of the sound source located on the back side and the side of the electronic device may be subjected to attenuation processing.

Referring to fig. 7, fig. 7 is a flowchart illustrating step S430 of the video capturing method illustrated in fig. 6 of the present application. As will be explained in detail with respect to the flow shown in fig. 7, the method may specifically include the following steps:

step S431: and acquiring sound source positions corresponding to the plurality of audio signals respectively.

In some embodiments, when the electronic device collects a plurality of audio signals through the microphone, a sound source position corresponding to each of the plurality of audio signals may be acquired. As one way, the electronic device may obtain the sound source positions corresponding to the plurality of audio signals through a sound source localization technique.

Step S432: and acquiring a sound source position located in the visual angle range of the front camera from the plurality of sound source positions as a first target sound source position, and acquiring a sound source position located in the visual angle range of the rear camera from the plurality of sound source positions as a second target sound source position.

In this embodiment, since the front camera is in the open state for video shooting, the viewing angle range of the front camera during video shooting and the position area corresponding to the viewing angle range can be obtained. Based on this, after the sound source positions corresponding to the plurality of audio signals are obtained, the sound source positions of the plurality of audio signals and the position area corresponding to the visual angle range of the front camera may be compared, respectively, to obtain the sound source position located within the visual angle range of the front camera from the plurality of sound source positions as the first sound source position.

In this embodiment, since the rear camera is in the open state for video shooting, the viewing angle range of the rear camera during video shooting and the position area corresponding to the viewing angle range can be obtained. Based on this, after the sound source positions corresponding to the plurality of audio signals are acquired, the sound source positions of the plurality of audio signals and the position area corresponding to the viewing angle range of the rear camera may be compared, respectively, to acquire the sound source position located within the viewing angle range of the rear camera from the plurality of sound source positions as the first sound source position.

Step S433: and acquiring an audio signal corresponding to the first target sound source position as the first audio signal, and acquiring an audio signal corresponding to the second target sound source position as the second audio signal.

In this embodiment, after the second target sound source position is determined, an audio signal corresponding to the second target sound source position may be acquired from among the plurality of audio signals as the second audio signal.

Step S440: and performing enhancement processing on the first audio signal and the second audio signal, and performing attenuation processing on audio signals except the first audio signal and the second audio signal in the plurality of audio signals.

In some embodiments, after determining the first audio signal corresponding to the front camera and the second audio signal corresponding to the rear camera, the first audio signal and the second audio signal may be subjected to enhancement processing, and the audio signals except the first audio signal and the second audio signal of the plurality of audio signals may be subjected to attenuation processing. It can be understood that, by the enhancement processing of the first audio signal and the second audio signal and the attenuation processing of the other audio signals, the source directions of the image signal and the audio signal of the video shooting can be basically consistent, and the video shooting effect can be improved.

As one mode, performing enhancement processing on the first audio signal and the second audio signal, and performing attenuation processing on an audio signal other than the first audio signal and the second audio signal among the plurality of audio signals may include: increasing the volume of the first audio signal and the second audio signal, and decreasing the volume of the audio signals other than the first audio signal and the second audio signal among the plurality of audio signals; increasing the gain of the first audio signal and the second audio signal, and decreasing the gain of the audio signals except the first audio signal and the second audio signal in the plurality of audio signals; the definition of the first audio signal and the second audio signal is improved, and the definition of the audio signals except the first audio signal and the second audio signal in the plurality of audio signals is reduced.

Step S450: when the audio signals corresponding to the front camera and the audio signals corresponding to the rear camera are not included in the audio signals, acquiring an audio signal with the maximum loudness from the audio signals as a third audio signal.

In some embodiments, when it is determined that the front camera of the electronic device is turned on and the rear camera of the electronic device is turned on, it may be detected whether an audio signal corresponding to the front camera is included in the plurality of audio signals collected by the microphone and whether an audio signal corresponding to the rear camera is included. If it is detected that the audio signals do not include the audio signal corresponding to the front camera and the audio signal corresponding to the rear camera, it can be considered that the audio signals having the same direction as the image signals do not exist in the plurality of acquired audio signals in the process of video shooting of the electronic device.

As a practical manner, when the audio signal corresponding to the front camera and the audio signal corresponding to the rear camera are not included in the plurality of audio signals, the audio signal with the highest loudness may be acquired from the plurality of audio signals as the third audio signal, that is, the audio signal with the highest loudness in the plurality of audio signals may be regarded as the audio signal that is most desirably acquired by the electronic device as the audio signal in the video.
