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. Moreover, 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.

Please refer to fig. 1, which is a schematic diagram illustrating a connection relationship between cameras in an electronic device. As shown in fig. 1, the application processor is connected to the camera and the modem, respectively. The radio frequency module is respectively connected with the modem and the antenna.

Because the antenna is close to the camera, electromagnetic waves generated when the antenna transmits power can interfere with signals in the camera, and the phenomenon of screen splash appears on the camera interface as shown in fig. 2. The screen-splash phenomenon is the phenomenon that a preview image displayed on a camera interface has stripes, snowflakes and other image loss phenomena.

In order to prevent the transmitting power of the antenna from interfering the normal work of the camera, the application processor can send a power reduction instruction to the modem when detecting that the camera is started. The modem sends the power down command to the radio frequency module. And the radio frequency module reduces the transmitting power of the antenna according to the power reduction instruction.

That is, the electronic device may reduce the transmit power of the antenna in response to activation of the camera. However, the camera of the electronic device is not necessarily interfered by the antenna when operating, and the degree of interference of the camera by the antenna may be different for different electronic devices.

Therefore, for electronic equipment with a camera not subjected to antenna interference or with a camera subjected to less antenna interference, reducing excessive transmission power when the camera is started wastes communication performance of the electronic equipment, and communication experience of a user is affected. For electronic equipment with a camera seriously interfered by an antenna, the problems of screen blooming, screen blockage, screen freezing and the like of a camera interface can not be solved by reducing too little transmitting power when the camera is started.

Exemplarily, the electronic device A1 includes a camera B1 and an antenna ant1, and the electronic device A2 includes a camera B2 and an antenna ant2. The camera B1 during operation can receive the interference of antenna ant1, and the camera B2 during operation can receive the interference of antenna ant2. When the camera B1 is started, the electronic device A1 controls the transmitting power of the antenna ant1 to be reduced by 5dB. When the camera B2 starts, the electronic device A2 controls the transmitting power of the antenna ant2 to be reduced by 5dB.

In a possible scenario, the antenna ant1 only needs to reduce 3dB to eliminate the interference to the camera B1, and the antenna ant2 only needs to reduce 7dB to eliminate the interference to the camera B2.

Before the power of the antenna is reduced, the camera interfaces of the electronic device A1 and the electronic device A2 both have the screen blooming phenomenon as shown in fig. 2. After powering down the antenna, the electronic device A1 eliminates the interference of the antenna to the camera, so that the camera interface can display the complete image as shown in fig. 3, but it reduces the transmission power by 2dB more, wasting part of the communication performance of the antenna. The electronic device A2 still has the problem of screen blooming as shown in fig. 2 because the influence of the antenna on the camera is not completely eliminated.

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.

In order to solve the above problem, an embodiment of the application provides an antenna power adjustment method and an electronic device, after detecting that a camera is started, it is first detected whether the camera is interfered by an antenna. If yes, the power of the antenna is reduced by a first preset value. And then continuously detecting whether the camera is interfered by the antenna. If so, continuously increasing the power of the antenna by taking the second preset value as a step length until the camera is detected to be interfered by the antenna, and reducing the power of the antenna by the second preset value. And if not, continuously reducing the power of the antenna by taking the second preset numerical value as the step length until the camera is detected not to be interfered by the antenna.

That is to say, first, when detecting that the camera is started, the embodiment of the present application does not directly reduce the power of the antenna, but detects whether the camera is interfered by the antenna. The power of the antenna is reduced in case the camera is disturbed by the antenna.

Secondly, when the power of the antenna is reduced, the first preset value is firstly reduced, and the power of the antenna is continuously adjusted by taking the second preset value as the step length until the power of the antenna just does not interfere with the camera.

Therefore, the antenna power adjusting method and the electronic device provided by the embodiment of the application can reduce the influence of the antenna power on the communication capability of the electronic device as much as possible while ensuring the normal work of the camera, and ensure the shooting experience and the communication experience of a user.

The window manager can obtain the size of the display screen, judge whether a status bar exists, lock the screen, intercept the screen and the like. The content provider is used to store and retrieve data, which may include video, images, audio, calls made and received, browsing history and bookmarks, phone books, etc., and makes the data accessible to applications. The phone manager is used to provide communication functions of the electronic device 400, such as management of call states (including on, off, etc.). The resource manager provides various resources, such as localized strings, icons, pictures, layout files, video files, etc., to the application. The notification manager enables the application to display notification information in the status bar, can be used to convey notification-type messages, can disappear automatically after a short dwell, and does not require user interaction. For example, a notification manager is used to notify that a download is complete, a message alert, etc. The notification manager may also be a notification that appears in the form of a chart or scrollbar text at the top status bar of the system, such as a notification of a background running application. The notification manager may also be a notification that appears on the screen in the form of a dialog window, such as prompting a text message in a status bar, sounding a prompt tone, vibrating the electronic device, flashing an indicator light, etc.

As an example 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 kernel layer at least comprises a data checking module, a data transmission module, a display driver, a camera driver, an audio driver and a sensor driver.

As an example of the application, the data transmission module is configured to receive image information sent by a camera, package the image information after receiving the image information, obtain a data packet including the image information, and transmit the data packet to the data verification module; after receiving the data packet, the data checking module may acquire checking information from the data packet, determine that dotting information exists in the image information and generate error reporting information under the condition that the checking information does not meet a preset condition, and then transmit the error reporting information to the antenna adjustment module in the application layer through the HAL layer and the application framework layer in sequence. The dotting information is information which affects the image display quality of the image information, and the preset condition is a preset condition.

As an example, the image information is data that satisfies an MIPI (Mobile Industry Processor Interface) protocol. The check information is an error rate of a data packet including the image information. The preset condition is that the preset condition is smaller than a preset threshold value. That is, after the data check module receives a data packet including image information, the data check module may obtain an error rate of the image information from the data packet. And when the error rate is greater than or equal to a preset threshold value, the data verification module determines that dotting information exists in the image information and generates first information for error reporting.

The workflow of the software and hardware of the electronic device is exemplarily described below with reference to a photographing scene.

The sensor module includes a touch sensor therein. When receiving the touch operation, the touch sensor converts the touch operation into an electric signal and sends the electric signal to the inner core layer. The kernel layer processes the electrical signal into an original input event (including touch coordinates, time stamp of touch operation, etc.). The raw input events are stored at the kernel layer. And the application program framework layer acquires the original input event from the kernel layer and identifies the control corresponding to the original input event. Taking the touch operation as a single-click operation, and taking a control corresponding to the single-click operation as a control of a camera application icon as an example, the application framework layer calls a software interface to start the camera application. And the camera application sends a camera opening instruction to the camera hardware management module, wherein the camera opening instruction is used for indicating to start the camera. When the camera hardware management module receives a camera opening instruction, the camera driving of the kernel layer is controlled to start the camera, and image information or video information is captured through the camera.

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 disclosure, and fig. 6 illustrates an example of turning on a camera by a camera application. By way of example and not limitation, the method is applied to a mobile phone equipped with a camera, and the mobile phone is illustrated by being implemented by a plurality of modules interactively as shown in fig. 5, and the method may include some or all of the following:

s601, responding to the operation of opening the camera application, and starting a camera of the mobile phone.

As an example, when a user wants to take a picture or record a video using a mobile phone while using the mobile phone, the user may click on an application icon of a camera application displayed in a screen of the mobile phone. The mobile phone can respond to the starting operation of the user on the application icon of the camera application to open the camera application. 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, a camera starting instruction can be issued to a camera hardware management module of the HAL layer. And after the camera hardware management module receives the camera starting instruction, controlling the camera to drive and start the camera.

It should be noted that the camera started by the mobile phone may be a front-facing camera or a rear-facing camera.

In a possible implementation manner, if the mobile phone turns off the rear camera used before the camera application last time, the default start of the camera application that is turned on this time may be the rear camera.

In another possible implementation manner, if the front-facing camera is used before the camera application is closed last time by the mobile phone, the front-facing camera may be started by default after the camera application is opened this time.

In yet another possible implementation, no matter which camera was used before the camera was last turned off, after the camera is turned on this time, the rear camera is started by default, or the front camera is started by default.

It should be noted that, here, the camera application is only described as an example of turning on the camera. In another embodiment, in the case that other applications such as shopping, videos, browsers, and the like have the authority to use a camera, the camera of the mobile phone may also be turned on in the process of implementing functions such as object identification, code scanning, and the like, and the specific manner of turning on the camera is the same as the above-mentioned manner, which is not described in detail in this embodiment of the present application.

S602, the camera collects first image information.

In this embodiment, the first image information is image information acquired by a camera before the power of the antenna is adjusted.

As an example, after the camera is started, an optical image may be generated through a lens (lens) and projected onto a surface of a sensor (sensor) of the camera. The sensor of the camera photoelectrically converts an optical image into an analog electrical signal. The analog-to-digital conversion module of the camera converts the analog electric signal into a digital signal to obtain image information in a digital signal format.

After the camera is started, the image information in the digital signal format can be sent to the data transmission module in real time.

S603, the camera sends the collected first image information to the data transmission module.

S604, the data transmission module packs the first image information to obtain a first data packet.

As an example, the data transmission module may package the first image information according to a specified format, and add a header and a trailer to obtain a first data packet. The header of the first data packet may include a data identifier (data identifier), a data packet size (word count), and an Error Checking Code (ECC).

It should be noted that the specific format may be set in advance, for example, the specific format may be YUV422, RAW8, RAW10, or the like.

In some embodiments, the data identifier is used to indicate a data type, a data packet size is used to indicate a size of the first data packet, an error checking code is used to check a data type of the first image information, whether a number of bytes occupied by the first image information changes, an error rate of the first image information, and the like.

S605, the data transmission module sends the first data packet to the data checking module.

S606, the data verification module verifies the first data packet to obtain the error rate of the first image information.

The first data packet is transmitted in the form of a digital signal, and may be affected by the antenna during transmission, which may cause various types of data in the first data packet to change. For example, the data in the header of the first data packet changes, and/or the data in the first image information changes, and/or the data in the trailer changes, etc.

The data checking module can check the first data packet to obtain the error rate of the first image information.

As an example, the data check module may parse the first data packet after receiving the first data packet. Illustratively, the data verification module analyzes a packet header of a data packet to obtain a data identifier, a size of the data packet, and an error check code included in the packet header, and the data verification module verifies first image information in the first data packet according to the error check code to obtain an error rate of the first image information.

In the embodiment of the present application, parsing the first packet may also be referred to as decoding the first packet.

S607, when the error rate of the first image is larger than or equal to the preset threshold value, the data verification module generates first information. The first information is used for indicating that the error rate of the first image information is larger than or equal to a preset threshold value.

In the embodiment of the application, when the error rate of the first image information is greater than or equal to the preset threshold, it may be determined that data in the first image information is interfered by an antenna, and a phenomenon such as screen splash may occur when the mobile phone displays a preview image corresponding to the first image information. When the error rate of the first image information is smaller than the preset threshold value, it can be determined that the data in the first image information is not interfered by the antenna, and the phenomenon of screen splash and the like can not occur when the preview image corresponding to the first image information is displayed by the mobile phone. Wherein, the preset threshold value can be 5%,10%, etc.

In the embodiment of the present application, the error rate of the image information is greater than or equal to the preset threshold value, which may also be referred to as existence of dotting information in the image information, and the error rate of the image information is less than the preset threshold value, which may also be referred to as absence of dotting information in the image information.

In addition, the data checking module can also determine whether the image information comprises dotting information in other modes. Illustratively, if a data packet is affected by the transmit power of the antenna, it may happen that the data verification module cannot parse the data packet. When the data check module cannot analyze the data packet, the data check module can also directly determine that dotting information exists in the image information.

It can be understood that the data verification module does not generate the first information in the case that the dotting information does not exist in the first image information.

S608, the data checking module sends the first information to the antenna adjusting module.

As an example, the data checking module may pass the first information to the antenna adjustment module of the application layer via the HAL layer and the application framework layer in sequence.

In an embodiment, when the data checking module does not successfully parse the first data packet, it indicates that the first image information is interfered by the antenna in the transmission process, and the data checking module may send the first information.

And S609, responding to the received first information, and sending a first instruction to the modem by the antenna adjusting module. The first instruction is used for instructing the modem to reduce the transmitting power of the target antenna by a first preset value.

Wherein the target antenna may also be referred to as the first antenna.

In a possible implementation manner, after receiving the first information, the antenna adjusting module may directly send a first instruction to a modem of the mobile phone, where the first instruction carries a first preset value; and after receiving the first instruction, the modem reduces the transmitting power of the target antenna by a first preset value.

It should be noted that the first preset value is a value preset according to requirements. Illustratively, the first preset value may be 5db, 6db, 7db, and so on. The target antenna includes at least one antenna that is predetermined to have an effect on the camera in the handset.

S610, in response to receiving the first instruction, the modem reduces the transmitting power of the target antenna by a first preset value.

For some electronic devices, after the transmitting power of the target antenna is reduced by the first preset value, the camera is no longer interfered by the target antenna. For other electronic devices, after the transmitting power of the target antenna is reduced by the first preset value, the camera still suffers interference from the target antenna. Therefore, in the embodiment of the present application, after the power of the target antenna is reduced, the data check module may determine whether the error rate of the image information in the new first data packet is smaller than a preset threshold, and execute different steps according to different determination results.

In the embodiment of the application, after the modem adjusts the power of the target antenna, a receipt of successful adjustment can be sent to the data verification module, so that the data verification module can judge whether the error rate of subsequent image information acquired by the camera meets the requirement or not.

S611, the data checking module judges whether the error rate of the second image information is smaller than a preset threshold value. If so, the following step S612a is performed. If not, the following S612b is executed. The second image information is image information currently acquired by the camera.

The second image information refers to the image information currently acquired by the camera after the transmitting power of the target antenna is reduced by the first preset value.

And S612a, the data checking module sends second information to the antenna adjusting module. The second information is used for indicating that the error rate of the second image information is smaller than a preset threshold value.

S613a, in response to receiving the second information, the antenna adjusting module sends a second instruction to the modem. The second instruction is used for instructing the modem to increase the transmitting power of the target antenna by a second preset value.

It should be noted that the second preset value is a value preset according to requirements. Illustratively, the second preset value may be 1db, 2db, 3db, and so on.

In the embodiment of the present application, the second predetermined value is smaller than the first predetermined value.

And S614a, in response to the second instruction, the modem increases the transmitting power of the target antenna by a second preset value.

S615a, the data checking module judges whether the error rate of the second image information is smaller than a preset threshold value. If yes, go to S612a. If not, jumping to S612b.

That is, the modem will continuously increase the transmitting power of the target antenna by the second preset value until the power of the target antenna is greater than or equal to the preset threshold, and then S612b is executed. S612b and subsequent steps are explained below.

And S612b, the data checking module sends third information to the antenna adjusting module. The third information is used for indicating that the error rate of the second image information is greater than or equal to a preset threshold value.

S613b, in response to receiving the third information, the antenna adjusting module sends a third instruction to the modem. The third instruction is for instructing the modem to decrease the transmit power of the target antenna by a second predetermined amount.

And S614b, in response to the third instruction, the modem reduces the transmitting power of the target antenna by a second preset value.

S615b, the data checking module judges whether the error rate of the second image information is smaller than a preset threshold value. If not, jumping to S612b. If yes, the process is ended.

That is, the modem will continuously adjust the transmitting power of the target antenna by using the second preset value as a step length until the error rate of the image information is just smaller than the preset threshold, that is, the transmitting power of the target antenna just does not cause interference to the camera. Therefore, the normal work of the camera is ensured, the amplitude of reducing the power of the antenna is reduced as much as possible, and the shooting experience and the communication experience of a user are ensured.

Taking the first preset value as 5dB and the second preset value as 1dB as an example, a specific process of applying the antenna power adjusting method provided by the embodiment of the present application to the electronic device A1 and the electronic device A2 in the foregoing example is described below.

For the electronic device A1, the transmitting power of the antenna ant1 is 26dB. When the transmitting power of the antenna ant1 is 23dB, the interference to the camera B1 can not be caused.

Before the antenna power adjustment method provided by the embodiment of the application is applied to the electronic device A1, the camera interface of the electronic device A1 has a screen splash phenomenon as shown in fig. 2.

When the camera application of the electronic device A1 is opened, the camera B1 is synchronously started. The camera can collect first image information and send the first image information to the data transmission module in real time. The data transmission module packs the first image information to obtain a first data packet, and sends the first data packet to the data verification module. The data verification module can verify the data to obtain the error rate of the first image information. As described above, the camera interface of the electronic device A1 may have a screen splash phenomenon as shown in fig. 2, that is, if the error rate of the first image information is greater than or equal to the preset threshold, the data verification module generates the first information, and sends the first information to the antenna adjustment module. In response to receiving the first information, the antenna adjustment module sends a first instruction to the modem. In response to receiving the first instruction, the modem reduces the transmit power of antenna ant1 by 5dB.

It can be understood that after the electronic device A1 reduces the transmission power of the antenna ant1 by 5dB, the transmission power of the antenna ant1 is 21dB, which is less than 23dB. Therefore, the camera interface of the electronic device A1 does not generate the screen splash phenomenon as shown in fig. 2.

However, for the electronic device A1, the interference of the antenna ant1 to the camera B1 can be avoided only by reducing the transmitting power of the antenna ant1 to 23dB, and reducing 2dB more can waste part of the communication performance of the antenna ant 1.

Therefore, please refer to fig. 7, which is a schematic diagram of an antenna power adjustment process according to an embodiment of the present application. As shown in fig. 7, in the embodiment of the present application, after the transmission power of the antenna ant1 is reduced by 5dB, the electronic device A1 continuously increases the transmission power of the antenna ant1 by using 1dB as a step length until the second image information includes dotting information, where the transmission power of the antenna ant1 is 24dB.

When the transmission power of the antenna ant1 is 24dB, the error rate of the second image information is greater than or equal to the first threshold. The electronic device then reduces the transmitting power of the antenna ant1 by 1dB to 23dB, so as to obtain the final transmitting power of the antenna ant 1. At this time, the camera interface of the electronic device A1 does not generate the screen splash phenomenon as shown in fig. 2.

It can be seen that, when the antenna power adjusting method provided by the embodiment of the application is applied to the electronic device A1, the normal operation of the camera B1 is ensured, the amplitude of reducing the antenna power is reduced as much as possible, and the shooting experience and the communication experience of a user are ensured.

For the electronic device A2, the transmission power of the antenna ant2 is 26dB. The transmitting power of the antenna ant2 is 19dB, and the interference to the camera B2 is avoided.

Before the antenna power adjusting method provided by the embodiment of the application is applied to the electronic device A2, a screen splash phenomenon may occur on a camera interface of the electronic device A2 as shown in fig. 2.

When the camera application of the electronic device A2 is opened, the camera B2 is synchronously started. The camera can collect first image information and send the first image information to the data transmission module in real time. The data transmission module packs the first image information to obtain a first data packet, and sends the first data packet to the data verification module. The data verification module can verify the data to obtain the error rate of the first image information. As described above, the camera interface of the electronic device A2 may have the screen splash phenomenon shown in fig. 2, that is, the error rate of the image information is greater than or equal to the preset threshold, the data verification module generates the first information, and sends the first information to the antenna adjustment module. In response to receiving the first information, the antenna adjustment module sends a first instruction to the modem. In response to receiving the first instruction, the modem reduces the transmit power of antenna ant2 by 5dB.

Therefore, after the electronic device A2 reduces the transmission power of the antenna ant2 by 5dB, the transmission power of the antenna ant2 is 21dB, which is greater than 19dB. The camera interface of the electronic device A2 still has the phenomenon of screen blooming as shown in fig. 2.

Therefore, in the embodiment of the present application, please refer to fig. 8, which is a schematic diagram of another antenna power adjustment process provided in the embodiment of the present application. As shown in fig. 8, after the transmission power of the antenna ant2 is reduced by 5dB, the electronic device A2 continuously reduces the transmission power of the antenna ant2 with 1dB as a step length until the second image information does not include dotting information. At this time, the transmitting power of the antenna ant2 is 19dB, and the screen splash phenomenon shown in fig. 2 does not occur on the camera interface of the electronic device A2.

It can be seen that, when the antenna power adjusting method provided by the embodiment of the application is applied to the electronic device A2, the normal operation of the camera B2 is ensured, the amplitude of reducing the antenna power is reduced as much as possible, and the shooting experience and the communication experience of a user are ensured.

The above-mentioned S601-S615 (including S615a and S615 b) describe the antenna power adjustment method provided by the embodiment of the present application in terms of interaction of the modules of the electronic device. The above process is described below in the context of an electronic device in conjunction with fig. 9.

And S901, responding to the operation of opening the camera application, and starting the camera.

And S902, acquiring first image information through a camera.

And S903, when the first image information comprises dotting information, reducing the transmitting power of the target antenna by a first preset value.

And S904, judging whether the second image information comprises dotting information. If so, the following S905a is performed. If not, the following S905b is executed.

And S905a, reducing the transmitting power of the target antenna by a second preset value. Wherein the second predetermined value is less than the first predetermined value.

S906a, judging whether the second image information comprises dotting information or not. If yes, jumping to S905a; if not, the process is ended.

And S905b, increasing the transmitting power of the target antenna by a second preset value.

S906b, judging whether the second image information comprises dotting information or not. If yes, jumping to S905a; if not, jumping to S905b.

It should be noted that all relevant contents of the steps related to the above method embodiment may be cited in the relevant description in fig. 6, and are not repeated herein.

In this embodiment of the application, the data verification module may further process the image information, so that a preview image corresponding to the image information is displayed in the electronic device. Please refer to fig. 10, which is a flowchart illustrating a preview image displaying image information according to an embodiment of the present application. The process mainly comprises the following substeps: 1. and the data checking module sends the image information to the camera hardware management module. 2. The camera hardware management module sends the image information to the view system. 3. The view system generates a corresponding preview image based on the image information. 4. The viewing system displays a preview image of the image information in a display screen.

As an example of the present application, when the dotting information is included in the image information, the mobile phone may not display a preview image of the image information, and automatically reduce the transmission power of the target antenna. And when the image information does not include dotting information, the mobile phone displays a preview image of the image information.

As an example of the application, when the image information includes dotting information, after the mobile phone displays a preview image corresponding to the image information, the user may autonomously select whether to reduce the transmission power of the target antenna, and if the user selects to reduce the transmission power of the target antenna, the user may double-click the mobile phone screen. In response to the trigger operation of the user on the mobile phone screen, the mobile phone can reduce the transmitting power of the target antenna.

As an example of the application, when the image information includes dotting information, referring to fig. 11, the mobile phone displays a preview image corresponding to the image information in a display interface of the camera application, and a first preset numerical value selection control and a second preset numerical value selection control are also displayed in the display interface of the camera application.

The user can trigger the first preset numerical value selection control through the first specified operation. In response to the user clicking the first preset value selection control, the mobile phone displays a power list as shown in fig. 12 in the display interface of the camera application, and the user selects a value from the power list. In response to a selection operation of the user in the power list, the handset may set the first preset value to the selected value.

Similarly, the user can trigger the second preset numerical value selection control through the first specified operation. And responding to the clicking operation of the user on the second preset numerical value selection control, displaying a power list in a display interface of the camera application by the mobile phone, and selecting a numerical value from the power list by the user. In response to a selection operation of the user in the power list, the handset may set the first preset value to the selected value.

After the user selects the first preset value, the power which is greater than or equal to the first preset value selected by the user in the power list of the second preset value is changed into an unselected state. After the user selects the second preset value, the power which is less than or equal to the second preset value selected by the user in the power list of the first preset value is changed into an unselected state.

As an example of the application, when the image information includes dotting information, after the mobile phone displays a preview image of the image information, a prompt message may be displayed in a pop-up window form, where the prompt message may prompt a user to reduce the transmission power of a target antenna due to the fact that a camera is interfered by the antenna.

The prompt information may be displayed not only in the form of a pop-up window, but also in other forms, for example, in the form of a bubble, a prompt box, or the like. The content of the prompt message may also be set in advance, for example, the prompt message may be "interfered by the antenna, the transmission power of the antenna has been reduced", "the camera is interfered by the antenna, the transmission power of the antenna needs to be reduced", and the like.

In addition, the prompt message may be displayed before the mobile phone adjusts the transmission power of the target antenna, as shown in fig. 13, before the mobile phone adjusts the transmission power of the target antenna, the mobile phone may display a prompt message 1301 on an interface displaying a preview image. The content of the prompt message 1301 may be "the transmission power of the antenna needs to be reduced due to the interference of the antenna on the camera", so as to prompt the user that the transmission power of the antenna needs to be reduced.

The prompt message may also be displayed after the mobile phone adjusts the transmission power of the target antenna, as shown in fig. 14, after the mobile phone adjusts the transmission power of the target antenna, the mobile phone may display a prompt message 1401 on the interface displaying the preview image. The content of the hint 1401 may be "interfered by the antenna, the transmission power of the antenna has been reduced" to hint the user that the handset has reduced the transmission power of the antenna.

As an example of the present application, when the image information includes dotting information, after the mobile phone displays a preview image of the image information, a query window 1501 as shown in fig. 15 may be displayed, if the user agrees to reduce the transmission power of the target antenna, a yes touch control may be triggered, and in response to a triggering operation of the yes touch control by the user, the mobile phone executes the antenna power adjustment method provided in the embodiment of the present application to adjust the power of the target antenna. If the user does not agree to reduce the transmitting power of the target antenna, the no touch control can be triggered, and the mobile phone does not adjust the transmitting power of the target antenna in response to the triggering operation of the no touch control by the user.

As an example of the present application, in response to a user's trigger operation of the "yes" touch control in the query window 1501, the mobile phone may display a first preset value selection control and a second preset value selection control in the display interface of the camera application, as in fig. 11.

In response to a first specified operation of the first preset value selection control by the user, the mobile phone displays a power list as shown in fig. 12 in a display interface of the camera application, and the user selects a value from the power list. In response to a selection operation of the user in the power list, the handset may set the first preset value to the selected value.

Based on the above description, it can be seen that the antenna power adjusting method provided by the embodiment of the application can reduce the influence of the antenna power on the communication capability of the electronic device as much as possible while ensuring the normal operation of the camera, and ensure the shooting experience and the communication experience of the user.
