Background

The application of the camera of the electronic equipment is more and more extensive, and a user can control the camera to shoot images, shoot videos and carry out live video broadcast through the camera application of the electronic equipment. As shown in fig. 1a, the camera 101 of the electronic device 100 is usually located close to the antenna 105 of the electronic device 100, and the camera 101 may be interfered by the transmission power of the antenna 105 of the electronic device 100 when operating, which may cause the user interface of the camera application to be jammed/flashed back/without image/screen splash.

In order to ensure the quality of the image/shot video collected by the camera, the electronic device can reduce the transmitting power of the antenna of the electronic device in the whole process from the start of the camera to the close of the camera. However, reducing the transmission power of the antenna deteriorates the communication capability of the electronic device. Therefore, how to reduce the influence of reducing the antenna power on the communication capability of the electronic device while ensuring the normal operation of the camera becomes a problem to be solved urgently.

Detailed Description

The terms "first", "second", and "third" in the embodiments of the present application are used to distinguish different objects, and are not used to define a specific order. Furthermore, the words "exemplary" or "such as" are used herein to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary" or "e.g.," is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present relevant concepts in a concrete fashion.

To facilitate understanding of the embodiments of the present application, the background of the application of the present application is described below.

Referring initially to FIG. 1b, FIG. 1b shows a hardware schematic of an electronic device 100 including a camera 101. As shown in fig. 1b, the electronic device 100 comprises: a camera 101, an application processor 102, a sar sensor103, and a baseband processor 104 and antenna 105.

The camera 101 is connected to an application processor 102 and a SAR Sensor103 (electromagnetic wave energy Absorption ratio Sensor), the SAR Sensor103 is connected to a baseband processor 104 (Modem), and the baseband processor 104 is connected to an antenna 105.

Wherein, the camera 101 is used for acquiring image data and sending the image data to the application processor 102,

the process of the camera 101 acquiring and transmitting image data may also be periodic. For example: a user takes a video for a period of 10 seconds using the camera 101 of the electronic apparatus 100, and the camera 101 takes 30 frames of images per second, that is, the camera 101 performs an operation of acquiring image data and transmitting the image data to the application processor 102 30 times per second. The process of the camera 101 sending image data to the application Processor 102 may be referred to as MIPI (Mobile Industry Processor Interface) output.

The application processor is used for coding and decoding the image data.

The SAR Sensor is used to send antenna power adjustment commands to the baseband processor.

The baseband processor may reduce or increase the transmit power of the antenna in accordance with the received antenna power adjustment instructions.

When the camera 101 of the electronic device 100 shown in fig. 1b acquires image data and sends the image data to the application processor 102 for processing, electromagnetic waves corresponding to the transmission power used when the antenna 105 transmits signals may interfere with the sending of the image data from the camera 101 to the application processor 102, that is, interfere with the MIPI output of the camera 101, so that the user interface of the camera application may have a screen splash phenomenon as shown in fig. 2. The screen splash phenomenon indicates that a preview image displayed on a user interface of a camera application has the phenomenon of image loss such as stripes and snowflakes.

At this time, in order to avoid the transmission power of the antenna from interfering with data transmission of the camera, the electronic device generally sends an antenna power adjustment instruction to the baseband processor through the SAR Sensor when detecting that the camera is started, and the baseband processor may reduce the transmission power of the antenna in a working process from start to stop of the camera in response to the antenna power adjustment instruction. However, reducing the transmission power of the antenna during the whole operation of the camera from the startup to the shutdown wastes the communication performance of the electronic device, and affects the communication experience of the user. The problem of how to reduce the influence of the transmission power of the antenna on the communication capability of the electronic equipment while ensuring the normal operation of the camera needs to be solved.

In order to solve the above problem, an embodiment of the present application provides an antenna power adjustment method for an electronic device with a shooting function, where the method includes: after the starting of the camera is detected, the starting time point and the required time length of MIPI output are determined according to the operation parameters of the camera, wherein the starting time point and the required time length of the MIPI output refer to the starting time point and the required time length of image data sent to an application processor (image processor) after the camera collects the image data.

And taking a time point which is a first preset time before the starting time point of the MIPI output as a trigger time point of the antenna power adjustment, wherein the trigger time point is earlier than the starting time point of the MIPI output.

When the trigger time point that the time is reached is detected, an antenna power adjustment signal (the antenna power adjustment signal may be referred to as an INT signal) may be controlled to be generated, and the SAR Sensor is controlled to send an antenna power adjustment instruction to the baseband processor, and the baseband processor is controlled to reduce the transmission power of the antenna until after the MIPI output is ended, that is, after the end time point of the MIPI output is reached. And controlling the SAR Sensor to send the antenna power adjusting instruction to the baseband processor again, so that the baseband processor recovers the transmitting power of the antenna.

In some embodiments, the sum of the time consumed by generating the antenna power adjustment signal and transmitting the antenna power adjustment instruction in response to the antenna power adjustment signal and the time consumed by the baseband processor to reduce the transmission power of the antenna may be taken as the first preset duration;

it is understood that the baseband processor may restore the transmission power of the antenna after a second preset time period of the end time point of the MIPI output. The second duration includes time consumed by changing the antenna power adjustment signal and transmitting the antenna power adjustment command in response to the antenna power adjustment signal and time consumed by the baseband processor to restore transmit power of the antenna.

That is, as shown in fig. 3, when detecting that the camera 101 is started, the embodiment of the present application does not directly reduce the transmission power of the antenna 105, but determines the duration of MIPI output of the camera according to the operating parameters of the camera 101, that is, determines the duration consumed by the camera 101 to transmit image data to the application processor 102.

In the embodiment of the application, before the transmission power of the antenna is reduced, a request response time period of an instruction is preset, sufficient response time is reserved for the SAR Sensor103 and the baseband processor 104 of the electronic device, the SAR Sensor103 can respond to an antenna power adjusting signal generated by the camera 101 in the request response time period and send an antenna power adjusting instruction to the baseband processor 104, and the baseband processor 104 reduces the transmission power of the antenna 105 according to the antenna power adjusting instruction, so that the electronic device can timely complete the operation of reducing the transmission power of the antenna in the MIPI output time period. After the camera 101 sends the image data to the application processor 102, that is, after the MIPI output duration is over, the camera 101 may change the antenna power adjustment signal, so that the SAR Sensor103 sends the antenna power adjustment instruction to the baseband processor 104 again, and the transmission power of the antenna 105 is recovered.

It can be understood that the electronic device is not always interfered by the transmitting power of the antenna, and the transmitting power of the antenna only interferes with the MIPI output of the camera. According to the antenna power adjusting method, the electronic equipment can reduce the transmitting power of the antenna in the time period when the camera sends the image data to the processor, and the transmitting power of the antenna is recovered in time after the image data is sent, so that the working process of the camera cannot be interfered by the transmitting power of the antenna, the time for reducing the transmitting power of the antenna can be shortened, and the influence on the communication capacity of the electronic equipment is reduced.

The hardware structure of the electronic device in the embodiment of the present application is described above with reference to fig. 4. The following describes a software architecture of an electronic device in an embodiment of the present application.

The software architecture of the electronic device may be a layered architecture, an event-driven architecture, a micro-core architecture, a micro-service architecture, or a cloud architecture. The following embodiments take an Android (Android) system with a layered architecture as an example to exemplarily illustrate a software system of an electronic device.

Please refer to fig. 5, which is a schematic diagram of a software architecture of an electronic device according to an embodiment of the present application. As shown in fig. 5. The layered architecture divides the software into several layers, each layer having a clear role and division of labor. The layers communicate with each other through a software interface. In some embodiments, the Android system is divided into four layers, an application layer, an application framework layer, a Hardware Abstraction Layer (HAL), and a kernel layer from top to bottom.

The application layer may include a series of application packages. As shown in fig. 5, the application packages may include camera, gallery, calendar, phone call, map, shopping, WLAN, music, video, short message, etc. applications.

After the camera application runs, the camera can be called to acquire image data through the camera. In one embodiment of the present application, the camera application may provide, but is not limited to, a photographing mode, a recording mode, a portrait mode, and the like, in any one of which the camera head may capture image data.

In an embodiment of the present application, if a video application, a shopping application, and the like have a right to use a camera, the application may also implement functions such as object recognition, code scanning, and the like through the camera. In the process of realizing any one of the functions, the camera can also collect image data.

The Application framework layer provides an Application Programming Interface (API) and a Programming framework for the Application program of the Application layer. The application framework layer includes a number of predefined functions. As shown in FIG. 5, the application framework layer may include a view system, a window manager, a content provider, a phone manager, a resource manager, a notification manager, and the like.

In an embodiment of the present application, the HAL layer at least includes a camera hardware management module, and the camera hardware management module is configured to control a camera driver of the kernel layer to start a camera when a camera opening instruction for requesting to open the camera is received by the application layer, so as to acquire image information through the camera. Therefore, the camera hardware management module can acquire the image information acquired by the camera. For example, after the camera is started, a camera opening instruction is sent to the camera hardware management module, after the camera hardware management module receives the camera opening instruction, the camera is controlled to drive and start the camera, after the camera is started, image information starts to be acquired, and the camera hardware management module acquires the image information.

The kernel layer is a layer between hardware and software. The inner core layer at least comprises a display driver, a camera driver, an audio driver, a sensor driver and an antenna power adjusting module. In the embodiment of the application, the antenna power adjusting module is used for acquiring the operating parameters of the camera through the camera drive and determining the MIPI output time of the camera according to the operating parameters; before the starting time point of the MIPI output time length, the antenna power adjusting module also determines a first time length before the camera sends image data to the application processor, and after the starting time point of the first time length is reached, the antenna power adjusting module generates an antenna power adjusting signal (the antenna power adjusting signal can be called an INT signal); and after the MIPI output time length is finished, the antenna power adjusting module changes the antenna power adjusting signal again, so that the SAR Sensor can control the baseband processor to reduce the transmitting power of the antenna within the MIPI output time length.

The antenna power adjustment method provided by the embodiment of the present application is described below with reference to the above description of the hardware structure and the software architecture of the electronic device. Please refer to fig. 6, which is a flowchart illustrating an antenna power adjustment method according to an embodiment of the present application, and fig. 6 illustrates an example in which a user opens a camera through a camera application of the electronic device 100 to perform video shooting. Taking the method applied to an electronic device equipped with a camera as an example, as a mobile phone, the mobile phone 100 may implement the antenna power adjusting method through interaction between the antenna power adjusting module shown in fig. 6 and multiple pieces of hardware, where the method may include some or all of the following:

s601: in response to an operation of opening the camera application 106, the cellular phone 100 starts the camera 101.

In the embodiment of the present application, when a user wants to take a picture or a video using the mobile phone 100 while using the mobile phone 100, the user may click an application icon of the camera application 106 displayed in the screen of the mobile phone 100. The cell phone 100 may open the camera application 106 in response to a user's launch operation of an application icon of the camera application 106. The starting operation may be a click operation, a long-time press operation, and the like, and is not limited specifically herein.

In the process loading process of the camera application 106, a camera start instruction may be issued to a camera hardware management module of the HAL layer. After receiving the camera start instruction, the camera hardware management module controls the camera to drive and start the camera 101.

It is understood that the camera 101 activated by the mobile phone 100 may be a front camera of the mobile phone, or may be a rear camera.

S602: the antenna power adjusting module 107 determines the duration of MIPI output according to the operating parameters of the camera.

In the embodiment of the present application, the duration of the MIPI output is the duration consumed by the camera 101 of the mobile phone 100 to transmit image data to the application processor 102. As shown in fig. 7, the duration of the MIPI output (which may be denoted by T3) may correspond to an operating parameter of the camera 101. The operating parameters of the camera 101 here may include: code stream, sampling rate, resolution, etc. Taking the code stream as an example, the unit of the code stream may be Mbps (Megabits Per Second, number of bits transmitted Per Second), the larger the code stream is, the larger the sampling rate in unit time is, the higher the precision of the data stream is, and the better the image quality is. For example: the duration of MIPI output corresponding to a code stream of 2Mbps may be 10 milliseconds, and the duration of MIPI output corresponding to a code stream of 20Mbps may be 20 milliseconds.

It can be understood that the correspondence between the operation parameter of the camera 101 and the MIPI output duration may be one-to-one, or many-to-one, that is, multiple operation parameters of the camera 101 may correspond to the same MIPI output duration. The above numerical values are given by way of example and are not limiting, and are not particularly limited herein.

S603: the camera 101 collects image data.

In the embodiment of the present application, the image data is image information collected by the camera before the transmission power of the antenna 105 is adjusted.

It is understood that after the camera 101 is started up, an optical image may be generated by the lens of the camera 101 and projected onto the surface of the optical sensor of the camera 101. The optical sensor of the camera 101 photoelectrically converts an optical image into an analog electric signal. The analog-to-digital conversion module of the camera 101 converts the analog electrical signal into a digital signal, and obtains image data in a digital signal format. After the camera 101 is started, image data in a digital signal format can be transmitted to the data transmission module in real time.

S604: the antenna power adjustment module 107 determines a first time period before the camera 101 sends image data to the application processor.

In this embodiment, the first duration may be a time period set before a start time point of sending the image data to the application processor by the camera of the mobile phone, that is, a time period set before a start time point of the duration of the MIPI output, where the first duration is used to reserve sufficient response time for the SAR Sensor and the baseband processor of the mobile phone. Referring to fig. 7, the first time period may be composed of two parts, where one part (T1) of the first time period is a time period required for the camera to generate the antenna power adjustment signal (INT signal), and the SAR Sensor sends an antenna power adjustment command to the baseband processor in response to the antenna power adjustment signal; another part (T2) of the first duration is the duration required for the baseband processor to control the antenna of the handset to reduce the transmit power of the antenna.

The value corresponding to the first time period may be determined by an empirical value or after the SAR Sensor and the baseband processor of the mobile phone are actually measured and distributed when the mobile phone leaves a factory, for example: the camera generates an antenna power adjusting signal, the time length required for the SAR Sensor to respond to the antenna power adjusting signal and send an antenna power adjusting instruction to the baseband processor can be 10 milliseconds, the baseband processor controls the antenna of the mobile phone, the time length required for reducing the transmitting power of the antenna can be 5 milliseconds, and then the value of the first time length is determined to be 15 milliseconds. It can be understood that the value of the first duration may also be slightly greater than the empirical value or a value determined after actual measurement distribution, so that it can be ensured that the SAR Sensor and the baseband processor of the mobile phone can have sufficient response time, and it is avoided that the baseband processor does not adjust the transmission power of the antenna of the mobile phone when the camera of the mobile phone starts to send image data to the application processor.

S605: at the beginning time point of the first duration, the antenna power adjustment module 107 generates a first antenna power adjustment signal.

In this embodiment, when the first duration begins, a time point before the camera of the mobile phone sends the image data to the application processor after acquiring the image data falls within a time period corresponding to the first duration.

The first antenna power adjustment signal may be a level signal, a value range of the level signal may be 0 and 1, a memory of the level signal may be set in a hardware structure of the mobile phone, and a camera of the mobile phone may modify the level signal in the memory by generating the first antenna power adjustment signal, for example: the initial value of the level signal in the memory may be 0, and the value of the level signal in the memory may become 1 after the camera of the mobile phone generates the first antenna power adjustment signal.

S606: in response to the first antenna power adjustment signal, after a first time period has elapsed, SAR Sensor103 controls baseband processor 104 to reduce the transmit power of antenna 105.

In this embodiment of the application, the SAR Sensor of the mobile phone may detect the value of the level signal in the memory described in step S605 in real time, as shown in fig. 7, after the SAR Sensor detects that the value of the level signal in the memory changes from 0 to 1, the SAR Sensor may send an antenna power adjustment instruction to the baseband processor, and the baseband processor reduces the transmission power of the antenna in response to the antenna power adjustment instruction.

It is understood that the procedure of reducing the transmission power of the antenna may be that the baseband processor reduces the transmission power of the antenna according to a preset value, for example: the preset value can be 5db, 6db, 7db, etc., and the transmitting power of the antenna of the mobile phone is reduced, wherein the antenna of the mobile phone can be at least one antenna which is preset to have an influence on the camera in the mobile phone. For example: as shown in fig. 7, the transmit power of the antenna of the handset is reduced from 26db to 23db.

S607: the camera 101 transmits image data to the application processor 102.

In this embodiment of the application, after a first time period elapses, that is, a camera of the mobile phone generates a first antenna power adjustment signal, the SAR Sensor detects that the first antenna power adjustment signal sends an antenna power adjustment instruction to the baseband processor, the baseband processor responds to the antenna power adjustment instruction, and after the transmission power of the antenna is reduced, the camera of the mobile phone can send acquired image data to the application processor, and the application processor can encode and decode the image data to convert the image data into an image or a video.

S608: after the duration of the MIPI output, the antenna power adjustment module 107 generates a second antenna power adjustment signal.

In the embodiment of the present application, the duration of the MIPI output may be that the camera of the mobile phone completes sending the image data to the application processor. In this case, the camera of the mobile phone may modify the level signal in the memory by generating a second antenna power adjustment signal, for example: the value of the level signal in the memory may be 1, and after the camera of the mobile phone generates the second antenna power adjustment signal, the value of the level signal in the memory may become 0.

S609: in response to the second antenna power adjustment signal, after a second duration has elapsed, the SAR Sensor103 controls the baseband processor 104 to restore the transmit power of the antenna.

In this embodiment of the application, the second time duration may be a time period set after a time point when the camera of the mobile phone finishes sending the image data to the application processor, and with reference to fig. 7, the second time duration may also be composed of two parts, where one part (T4) of the second time duration is a time duration required for the camera to generate the antenna power adjustment signal, and the SAR Sensor sends the antenna power adjustment instruction to the baseband processor in response to the antenna power adjustment signal; another portion (T5) of the second duration is the duration required for the baseband processor to control the antenna of the handset to recover the transmit power of the antenna.

The SAR Sensor of the mobile phone can detect the value of the level signal in the memory in real time, after the SAR Sensor detects that the value of the level signal in the memory is changed from 1 to 0, the SAR Sensor can send an antenna power adjusting instruction to the baseband processor, and the baseband processor responds to the antenna power adjusting instruction to recover the transmitting power of the antenna.
