Background

At present, a high-pass platform CODEC (coder-decoder) has only four paths of ADCs (Analog-to-Digital converters) at most, HDR (high dynamic range) recording needs to connect two paths of ADCs with one path of MIC (microphone), and the two paths of ADCs are respectively configured with high and low gains, so that the dynamic range of recorded audio is expanded, and the definition under the high-sound-pressure environment is improved. However, this solution is not at all problematic if only two-way MIC is used, but there is an increasing market demand for sound recording, and three-way MIC is applied, for example: the functions of remote sound pickup, video zooming, video focus tracking, directional sound pickup and the like are more and more, and at the moment, if three MICs are connected, a hardware circuit has no way of being compatible with related applications which simultaneously use HDR sound recording and the three MICs. If two ADC paths are added, the pressure is large for the cost of hardware.

At present, a mobile phone with two MICs can use the HDR recording function, and a mobile phone with three MICs cannot use the HDR recording function. In terms of the prior art, the related recording extension functions of HDR recording and three-way MIC cannot be compatible on mobile phone applications on the basis of three-way MIC and four-way ADC.

The use of the terms "a," "an," or "the" and similar referents in the context of this application are not to be construed as limiting in number, but rather as indicating the presence of at least one.

The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

The electronic device according to the embodiment of the present application may include a handheld device, a vehicle-mounted device, a wearable device, a computing device, and various User Equipment (UE), a Mobile Station (MS), a terminal device (terminal device), and the like. For convenience of description, the above-mentioned devices are collectively referred to as electronic devices.

Referring to fig. 1 and fig. 2, in the prior art, when the

electronic device

200, 200a includes a three-way microphone 201 and a four-way analog-to-digital conversion module 202, two schemes are provided for connecting the three-way microphone 201 and the four-way analog-to-digital conversion module 202, the first scheme refers to fig. 1, in which one microphone 201 is connected to the two-way analog-to-digital conversion module 202, and the other two microphones 201 are respectively connected to the one-way analog-to-digital conversion module 202, at this time, when the HDR recording function is used for recording, the recorded audio file can only be monaural. Referring to fig. 2, in a second scheme, two microphones 201 of the three microphones 201 are respectively connected to two analog-to-digital conversion modules 202, and the other microphone 201 is not used, so that a stereo effect can be ensured during HDR recording, but functions related to the three microphones 201 cannot be used. Applications that require the three microphones 201 to work simultaneously may include, but are not limited to, applications that apply functions such as remote sound pickup, video zooming, video focus tracking, and directional sound pickup. The video zooming is that when a user zooms a lens during video shooting, sound is focused and amplified simultaneously, the principle of beam forming is mainly utilized, if the sound is realized by utilizing two paths of MICs, the sound can also be realized, but no way is available for distinguishing the sound at the same distance in front and at the same time, the sound in front and at the back after zooming is amplified, the effect is poor, the sound in front and at the back can be distinguished by three paths of MICs, and the signal-to-noise ratio of the three paths of MICs is improved by 3-6 dB compared with that of the two paths of MICs. Video focus tracking refers to video shooting, when a user needs to track and shoot a main body, the user also wants to track sound, face tracking or object tracking is utilized at the moment, angle information is sent to a recording module, after the angle information is received, a beam angle moves to a corresponding angle position to perform directional tracking and identification of the sound, at the moment, if the sound is realized by two paths of MICs, the sound can also be realized, but the sound at the same distance in the front and the back can not be distinguished, if the user runs to a shooting person, the sound can not be distinguished at the position, the effect is poor, three paths of MICs can distinguish the sound in the front and the back, and the signal-to-noise ratio of the three paths of MICs is improved by 3-6 dB compared with 2 MICs.

Obviously, there is no way in the prior art to simultaneously compatible the HDR recording and the related recording extension function of the three-way microphone on the basis of the three-way microphone 201 and the four-way analog-to-digital conversion module 202.

In order to solve the compatibility problem of the related recording extension functions of the HDR recording and the three-way microphone, the following schemes are proposed in the application. Specifically, please refer to fig. 3, in which fig. 3 is a schematic block diagram of an electronic device according to an embodiment of the present application. The electronic device 100 includes a memory 11, a processor 12, a three-way microphone 13, and a four-way analog-to-digital conversion module 14. The memory 11 stores a computer program for processing by the processor 12, and the processor 12 executes the computer program to perform the following steps:

detecting sound pressure of a current recording environment when the electronic device 100 starts recording, and judging whether the sound pressure exceeds a preset sound pressure threshold according to a detection result so as to confirm whether the electronic device 100 uses HDR recording to obtain a first judgment result;

judging whether the electronic device 100 is running an application requiring the three microphones 13 to work simultaneously to obtain a second judgment result;

and adjusting the connection relationship between the three-way microphone 13 and the four-way analog-to-digital conversion module 14 based on the first determination result and the second determination result.

Therefore, in the present application, the connection relationship between the three-way microphone 13 and the four-way analog-to-digital conversion module 14 may be adjusted based on the first determination result and the second determination result, so that the HDR recording function is implemented by changing the connection relationship between the three-way microphone 13 and the four-way analog-to-digital conversion module 14, and the related functions of running applications that need to work simultaneously with the three-way microphone 13 are implemented, and the HDR recording function is compatible with the functions of running applications that need to work simultaneously with the three-way microphone 13, so as to achieve the purpose of expanding the recording function and reduce the production cost without adding an analog-to-digital conversion module.

Further, please refer to fig. 4, wherein fig. 4 is a circuit diagram of the electronic device according to an embodiment of the present application. In one embodiment, the three-way microphone 13 includes a first microphone 131, a second microphone 133, and a third microphone 135. The first microphone 131 is disposed on the top of the front side of the electronic apparatus 100, i.e., adjacent to the front camera, the second microphone 133 is disposed on the top of the back side of the electronic apparatus 100, i.e., adjacent to the back camera, and the third microphone 135 is disposed on the bottom of the electronic apparatus 100. The four analog-to-digital conversion modules 14 include a first analog-to-digital conversion module 141, a second analog-to-digital conversion module 143, a third analog-to-digital conversion module 145 and a fourth analog-to-digital conversion module 147; the electronic device 100 further includes a first switch group 151, a second switch group 153, a third switch group 155, a fourth switch group 157, and a fifth switch group 159. The first switch set 151 is connected between the first microphone 131 and the first analog-to-digital conversion module 141; the second switch group 153 is connected between the first microphone 131 and the second analog-to-digital conversion module 143; the third switch group 155 is connected between the second microphone 133 and the third analog-to-digital conversion module 145; the fourth switch group 157 is connected between the third microphone 135 and the third analog-to-digital conversion module 145; the fifth switch group 159 is connected between the third microphone 135 and the fourth analog-to-digital conversion module 147. The processor 12 controls the on states of the first switch group 151, the second switch group 153, the third switch group 155, the fourth switch group 157 and the fifth switch group 159 based on the first determination result and the second determination result to adjust the connection relationship between the three-way microphone 13 and the four-way analog-to-digital conversion module 14.

Therefore, based on the first determination result and the second determination result, the connection relationship between the three-way microphone 13 and the four-way analog-to-digital conversion module 14 is adjusted by adjusting the respective conduction conditions of the first switch group 151, the second switch group 153, the third switch group 155, the fourth switch group 157 and the fifth switch group 159, so as to implement both the HDR recording function and the related function of running the application requiring the three-way microphone 13 to work simultaneously, achieve the compatibility between the HDR recording function and the function of running the application requiring the three-way microphone 13 to work simultaneously, and achieve the purpose of expanding the recording function and reducing the production cost without increasing the number of analog-to-digital conversion modules.

Further, in one embodiment, the first analog-to-digital conversion module 141 has a first gain, the second analog-to-digital conversion module 143 has a second gain, the third analog-to-digital conversion module 145 has a third gain, and the fourth analog-to-digital conversion module 147 has a fourth gain. The magnitudes of the first gain, the second gain, the third gain, and the fourth gain may be determined by the conduction conditions of the first switch group 151, the second switch group 153, the third switch group 155, the fourth switch group 157, and the fifth switch group 159, so that the connection relationship between the three-way microphone 13 and the four-way analog-to-digital conversion module 14 may be adjusted in an auxiliary manner, that is, the HDR recording function is implemented, the related function of running the application requiring the simultaneous operation of the three-way microphone 13 is implemented, the HDR recording function is compatible with the function of running the application requiring the simultaneous operation of the three-way microphone 13, and the recording function is extended and the production cost is reduced without adding an additional analog-to-digital conversion module.

Specifically, in one embodiment, the first analog-to-digital conversion module 141 includes a first analog-to-digital converter 1411 and a first gain unit 1413, and the first gain unit 1413 is connected between the first analog-to-digital converter 1411 and the first switch set 151; the second analog-to-digital conversion module 143 includes a second analog-to-digital converter 1431 and a second gain unit 1433, wherein the second gain unit 1433 is connected between the second switch group 153 and the second analog-to-digital converter 1431; the third analog-to-digital conversion module 145 includes a third analog-to-digital converter 1451 and a third gain unit 1453, the third gain unit 1453 is connected between the third switch set 155 and the third analog-to-digital converter 1451, and the third gain unit 1453 is further connected between the fourth switch set 157 and the third analog-to-digital converter 1451; the fourth adc module 147 includes a fourth adc 1471 and a fourth gain unit 1473, and the fourth gain unit 1473 is connected between the fifth switch group 159 and the fourth adc 1471.

Thus, based on the adjustment of the amplification factors of the first 1413, second 1433, third 1453 and fourth 1473 gain units, the magnitudes of the first, second, third and fourth gains may be adjusted.

Further, in one embodiment, the processor 12 executes the computer program to perform the steps of detecting the sound pressure of the current sound recording environment when the electronic device 100 starts sound recording, including:

the first microphone 131 is controlled to be turned on and recording of the environmental volume is performed to detect the sound pressure of the current recording environment, and the second microphone 133 and the third microphone 135 are controlled to be turned off, that is, one of the first switch set 151 and the second switch set 153 is controlled to be turned on, so that the purpose of recording the environmental volume to detect the sound pressure of the current recording environment is achieved.

Further, in one embodiment, after the audio signal recorded by the first microphone 131 is superimposed with the gain of the corresponding analog-to-digital conversion module, the superimposed audio signal may be converted into an electrical signal to obtain a sound pressure, and the sound pressure is compared with a preset sound pressure threshold. When the sound pressure is greater than a preset sound pressure threshold, it is determined that the sound pressure exceeds the preset sound pressure threshold, and at this time, if the first microphone 131 continues to be connected with the single-path analog-to-digital conversion module, the recording of the first microphone 131 will be distorted, and needs to be switched to HDR recording, that is, the first microphone 131 is controlled to be connected with the two-path analog-to-digital conversion module at the same time.

It should be explained that, when the first microphone 131 is connected to the one-way analog-to-digital conversion module, the dynamic range of the first microphone 131 is determined by the current recording bit number, and if the current recording bit number is 16 bits, the dynamic range that the one-way analog-to-digital conversion module can record is 96dB. When the first switch group 151 and the second switch group 153 are both turned on, the first microphone 131 is connected to two analog-to-digital conversion modules, which correspond to a low gain and a high gain, respectively, where the high gain and the low gain are relative concepts, a gain value of the high gain is greater than a gain value of the low gain, and a difference between the high gain and the low gain is greater than a preset threshold. Therefore, the purpose of expanding the dynamic range of the first microphone 131 can be achieved by a method of superimposing two signals.

Therefore, compared with a mode of adding two analog-to-digital conversion modules, the mode of adding the switch group in the application saves cost, and can intelligently switch the connection relation between the three-way microphone 13 and the four-way analog-to-digital conversion module 14 according to the detection of environmental sound pressure and user behavior, thereby solving the technical problem that only the four-way analog-to-digital conversion module 14 is available at present, and three-way microphones cannot be compatible to realize HDR recording function and video focus-following zoom recording function.

Further, in one embodiment, the step executed by the processor 12 executing the computer program to determine whether the sound pressure exceeds a preset sound pressure threshold to confirm whether the electronic device 100 uses HDR recording includes:

determining that the electronic device 100 is using an HDR recording when the sound pressure exceeds the preset sound pressure threshold;

determining that the electronic device 100 is not using HDR recording when the sound pressure does not exceed the preset sound pressure threshold.

Further, in one embodiment, the step executed by the processor 12 running the computer program adjusts the connection relationship between the three-way microphone 13 and the four-way analog-to-digital conversion module 14 based on the first determination result and the second determination result, which includes the following three cases, as described in detail below.

Wherein, the first condition is:

when the first determination result indicates that the electronic device 100 currently uses an HDR recording and the second determination result indicates that the electronic device 100 does not run an application that requires the three microphones 13 to operate simultaneously, the first switch group 151, the second switch group 153, the fourth switch group 157, and the fifth switch group 159 are controlled to be turned on, and the third switch group 155 is controlled to be turned off.

At this time, the first microphone 131 is simultaneously connected to the first analog-to-digital conversion module 141 and the second analog-to-digital conversion module 143, the second microphone 133 does not operate, and the third microphone 135 is simultaneously connected to the third analog-to-digital conversion module 145 and the fourth analog-to-digital conversion module 147. At this time, the first gain is different from the second gain, and the third gain is different from the fourth gain, for example, as shown in fig. 5, the first analog-to-digital conversion module 141 corresponds to a low gain, and the second analog-to-digital conversion module 143 corresponds to a high gain, and the signal of the first analog-to-digital conversion module 141 and the signal of the second analog-to-digital conversion module 143 are superimposed by an algorithm, so as to achieve the purpose of extending the dynamic range of the first microphone 131 by 30 dB. Similarly, the third analog-to-digital conversion module 145 corresponds to a low gain, and the fourth analog-to-digital conversion module 147 corresponds to a high gain, and the purpose of expanding the dynamic range of the third microphone 135 is also achieved by superimposing the signal of the third analog-to-digital conversion module 145 and the signal of the fourth analog-to-digital conversion module 147. Therefore, the first microphone 131 and the third microphone 135 are respectively connected to two analog-to-digital conversion modules, so that a dual dynamic stereo recording effect of HDR recording can be achieved.

Wherein the second case is:

when the first determination result is that the electronic device 100 does not currently use the HDR recording, the first switch group 151, the third switch group 155, and the fifth switch group 159 are controlled to be turned on, and the second switch group 153 and the fourth switch group 157 are controlled to be turned off.

Alternatively, in one embodiment, when the first determination result indicates that the electronic device 100 does not currently use an HDR recording and the second determination result indicates that the electronic device 100 does not run an application that requires the three-way microphone 13 to operate simultaneously, the first switch set 151, the third switch set 155, and the fifth switch set 159 are controlled to be turned on, and the second switch set 153 and the fourth switch set 157 are controlled to be turned off.

Optionally, in another embodiment, when the first determination result is that the electronic device 100 does not currently use an HDR recording, it is not necessary to determine whether the electronic device 100 is running an application that requires the three microphones to operate simultaneously to obtain a second determination result, and at this time, the first microphone 131, the second microphone 133, and the third microphone 135 are respectively connected to one analog-to-digital conversion module, so as to implement normal sound reception.

At this time, the first microphone 131, the second microphone 133 and the third microphone 135 are respectively connected to one analog-to-digital conversion module, so as to realize normal sound reception.

Wherein the third case is:

when the first determination result is that the electronic device 100 currently uses an HDR recording and the second determination result is that the electronic device 100 runs an application that requires the three microphones 13 to operate simultaneously, the first switch group 151, the second switch group 153, the third switch group 155, and the fifth switch group 159 are controlled to be turned on, and the second switch group 153 is controlled to be turned off.

At this time, the first microphone 131 is connected to two analog-to-digital conversion modules, and the second microphone 133 and the third microphone 135 are respectively connected to one analog-to-digital conversion module, so that compatibility between HDR recording and running of applications requiring simultaneous operation of the three microphones 13 can be simultaneously achieved, the recording effect of the three microphones 13 is ensured, and the recording definition and dynamic range are improved.

Further, in an embodiment, when the first determination result is that the electronic device 100 is currently using an HDR recording and the second determination result is that the electronic device 100 is running an application that requires the three-way microphone 13 to operate simultaneously, the first gain and the second gain are different, and the third gain and the fourth gain are the same as a lower gain of the first gain and the second gain.

Therefore, when the sound pressure exceeds a preset sound pressure threshold, the second microphone 133 and the third microphone 135 have the same low gain as the first microphone 131, so as to avoid sound break, and the dynamic range of the first microphone 131, the second microphone 133 and the third microphone 135 can be increased when they are operated simultaneously.

Referring to fig. 6, fig. 6 is a flowchart illustrating a method compatible with video and audio recording according to an embodiment of the present application. The method compatible with video and audio recording is applied to the electronic device 100. The electronic device 100 includes a three-way microphone 13 and a four-way analog-to-digital conversion module 14. The method for compatible video and audio recording comprises the following steps:

step 611: detecting sound pressure of a current recording environment when the electronic device 100 starts recording, and judging whether the sound pressure exceeds a preset sound pressure threshold according to a detection result so as to confirm whether the electronic device 100 uses HDR recording to obtain a first judgment result;

step 613: judging whether the electronic device 100 is running an application requiring the three microphones 13 to work simultaneously to obtain a second judgment result;

step 615: and adjusting the connection relationship between the three-way microphone 13 and the four-way analog-to-digital conversion module 14 based on the first determination result and the second determination result.

Therefore, in the present application, the connection relationship between the three-way microphone 13 and the four-way analog-to-digital conversion module 14 may be adjusted based on the first determination result and the second determination result, so that the HDR recording function is realized by changing the connection relationship between the three-way microphone 13 and the four-way analog-to-digital conversion module 14, the related functions of running applications that need the three-way microphone 13 to work simultaneously are also realized, the HDR recording function is compatible with the functions of running applications that need the three-way microphone 13 to work simultaneously, and the purpose of expanding the recording function and reducing the production cost are achieved without increasing an additional analog-to-digital conversion module.

Step 415 specifically includes:

and controlling the conduction conditions of the first switch group 151, the second switch group 153, the third switch group 155, the fourth switch group 157 and the fifth switch group 159 based on the first judgment result and the second judgment result to adjust the connection relationship between the three-way microphone 13 and the four-way analog-to-digital conversion module 14.

Further, in one embodiment, the method for compatible video and audio recording includes the steps of:

controlling the first analog-to-digital conversion module 141 to have a first gain;

controlling the second analog-to-digital conversion module 143 to have a second gain;

controlling the third analog-to-digital conversion module 145 to have a third gain;

the fourth analog-to-digital conversion module 147 is controlled to have a fourth gain.

The magnitudes of the first gain, the second gain, the third gain, and the fourth gain may be determined by the conduction conditions of the first switch group 151, the second switch group 153, the third switch group 155, the fourth switch group 157, and the fifth switch group 159, so that the connection relationship between the three-way microphone 13 and the four-way analog-to-digital conversion module 14 may be adjusted in an auxiliary manner, that is, the HDR recording function is implemented, the related function of running the application requiring the three-way microphone 13 to work simultaneously is implemented, the HDR recording function is compatible with the function of running the application requiring the three-way microphone 13 to work simultaneously, and the purpose of expanding the recording function and reducing the production cost are achieved without adding an additional analog-to-digital conversion module.
