[0026] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0027] With the development of imaging technology, it has become popular to equip electronic devices such as mobile phones and tablet computers with cameras. Even if users do not have professional cameras, they can use the cameras in electronic devices to take pictures at any time.

[0028] However, the shooting quality of the camera in the electronic device is easily affected by many factors, resulting in poor shooting quality. The inventor of the present application has found through a large number of research experiments that in some specific scenarios, when the camera is shooting images or videos, if the electronic device is in a weak signal scenario, the transmission power of the antenna in the electronic device will be relatively large, and if the antenna is close to the camera, the high transmission power of the antenna will cause signal interference to the camera, causing the camera's shooting screen to appear distorted and stuck, resulting in poor camera shooting quality, which may affect the user's normal use of the shooting function of the electronic device.

[0029] For example, see Figure 1 , Figure 1 In the electronic device 100 shown, ANT10 ( Figure 1 The antenna 101 shown is a transmitting antenna for cellular signals. The distance between ANT10 and the camera 102 is relatively close. When the camera 102 is shooting images or videos, if the transmission power of ANT10 is relatively large, it may cause signal interference to the MIPI (Mobile Industry Processor Interface, serial communication interface) communication in the camera 102, thereby causing the screen to be distorted or stuck in the shooting picture of the camera 102, affecting the user's normal shooting.

[0030] In view of this, embodiments of the present application provide a power control method, device, electronic device, storage medium, and program product, which can improve the shooting quality of a camera in an electronic device.

[0031] The power control method provided in the embodiment of the present application can be applied to electronic devices. The electronic devices may be, but are not limited to, various personal computers, laptops, smart phones, tablet computers, Internet of Things devices, and portable wearable devices. The Internet of Things devices may be smart speakers, smart TVs, smart air conditioners, smart car devices, projection devices, etc. The portable wearable devices may be smart watches, smart bracelets, head-mounted devices, etc. The head-mounted devices may be virtual reality (VR) devices, augmented reality (AR) devices, smart glasses, etc.

[0032] In an embodiment of the present application, a camera module and a radio frequency module are configured in the electronic device. The camera module includes a lens, an image sensor, an image signal processor, etc. The radio frequency module includes a radio frequency processor, a power amplifier, a low-noise amplifier, a switch, etc. The radio frequency module is connected to each antenna in the electronic device.

[0033] In an exemplary embodiment, Figure 2 As shown, a power control method is provided, and the method is applied to an electronic device as an example for explanation. The electronic device is equipped with a camera module and a radio frequency module. The power control method includes the following steps 201 to 203:

[0034] Step 201: The camera module is in working mode and detects whether a power limit condition is met.

[0035] The working mode may include a preview mode and a shooting mode. The camera module may have multiple preview modes, and each preview mode corresponds to a shooting mode. Taking the preview mode as an example, such as a photo preview mode, a recording preview mode, a portrait preview mode, etc., after the camera module is started, it may enter a default preview mode, and the user may select the desired preview mode to switch as needed.

[0036] In an embodiment of the present application, when the camera module is in any preview mode or shooting mode, it can detect whether the power limit condition is currently met. The power limit condition is used to indicate that the shooting picture corresponding to the camera module has screen distortion and / or freezes.

[0037] If the camera module detects that the power limit condition is met, it means that the shooting picture corresponding to the camera module has a distorted screen and / or a stuck screen; conversely, if the camera module detects that the power limit condition is not met, it means that the shooting picture corresponding to the camera module does not have a distorted screen and a stuck screen.

[0038] For example, during MIPI communication inside the camera module, the camera module can detect whether the bit error rate of data packet transmission is greater than a preset bit error rate threshold. If the bit error rate is greater than the preset bit error rate threshold, it is determined that the captured image has a distorted screen and / or stuck, thereby determining that the power limit condition is met; conversely, if the bit error rate is less than or equal to the preset bit error rate threshold, it is determined that the captured image does not have a distorted screen and stuck, thereby determining that the power limit condition is not met. The preset bit error rate threshold can be flexibly set during implementation.

[0039] Step 202: If the power limit condition is met, the camera module sends an interference instruction.

[0040] When the camera module detects that the power limit condition is met, the camera module sends an interference instruction, which is used to instruct the RF module to interfere with the signal of the camera module.

[0041] Exemplarily, the camera module may send the interference instruction in the form of broadcasting.

[0042] Step 203: The radio frequency module reduces the transmission power of the radio frequency signal currently transmitted by the target antenna in the electronic device in response to the interference instruction.

[0043] After the RF module receives the interference instruction, the RF module responds to the interference instruction and reduces the transmission power of the RF signal currently transmitted by the target antenna in the electronic device, and the distance between the target antenna and the camera module is less than a preset distance threshold. The preset distance threshold can be set by itself during implementation, for example, it can be set to a smaller distance value. If the distance between the target antenna and the camera module is less than the preset distance threshold, it indicates that the target antenna is close to the camera module, thereby reducing or eliminating the signal interference of the RF module to the camera module.

[0044] In a possible implementation of step 203, the RF module can determine one or more antennas in the electronic device that are currently transmitting RF signals, and select a target antenna that is closest to the camera module from the one or more antennas. Next, the RF module determines the frequency band used by the target antenna to currently transmit RF signals, and then reads the maximum transmission power corresponding to the target antenna and the frequency band from a preset storage location, and uses the maximum transmission power to limit the transmission power of the target antenna to reduce the transmission power of the target antenna.

[0045] Among them, the maximum transmission power corresponding to the target antenna and the frequency band can be obtained in advance. The maximum transmission power is the maximum allowable transmission power that will not cause signal interference to the camera module after testing. In this way, while avoiding the RF module from causing signal interference to the camera module, the communication quality can be guaranteed as much as possible.

[0046] Other possible implementations of step 203 will be described in the following embodiments.

[0047] In the above embodiment, the camera module in the electronic device detects whether the power limitation condition is met in the working mode, and the power limitation condition is used to characterize that the shooting picture corresponding to the camera module has a distorted screen and / or a jamming. If the power limitation condition is met, it indicates that the shooting picture has a distorted screen and / or a jamming. The camera module sends an interference instruction, and the radio frequency module in the electronic device responds to the interference instruction to reduce the transmission power of the radio frequency signal currently transmitted by the target antenna in the electronic device. The distance between the target antenna and the camera module is less than a preset distance threshold. In this way, by reducing the transmission power of the target antenna (the target antenna is closer to the camera module), it is possible to avoid excessive transmission power of the target antenna from causing signal interference to the camera module, thereby solving the problem of distorted screen and / or jamming in the shooting picture caused by the signal interference, and improving the shooting quality of the camera.

[0048] In one embodiment, Figure 2 Based on the embodiment shown, see Figure 3 This embodiment introduces another possible implementation method of reducing the transmission power of the radio frequency signal currently transmitted by the target antenna in the electronic device in response to the interference instruction by the radio frequency module.

[0049] See also Figure 3 , step 203 may include Figure 3 Step 301 and step 302 shown:

[0050] Step 301: The radio frequency module obtains at least one mapping relationship.

[0051] The above mapping relationships may be preset in the RF module, and the RF module obtains the preset mapping relationships.

[0052] Each mapping relationship includes a corresponding relationship between an antenna identifier, a frequency band identifier, and a maximum transmit power, and the distance between the antenna corresponding to each antenna identifier and the camera module is less than a preset distance threshold.

[0053] For one antenna, the antenna may support one frequency band or multiple frequency bands. When the antenna supports multiple frequency bands, the antenna corresponds to multiple mapping relationships, and the multiple mapping relationships correspond one-to-one to the multiple frequency bands supported by the antenna.

[0054] For example, antenna 1 supports frequency band 1, frequency band 2 and frequency band 3, then antenna 1 corresponds to mapping relationship 1, mapping relationship 2 and mapping relationship 3, wherein mapping relationship 1 includes the antenna identifier of antenna 1, the frequency band identifier of frequency band 1 and the maximum transmit power allowed when antenna 1 transmits radio frequency signals in frequency band 1, mapping relationship 2 includes the antenna identifier of antenna 1, the frequency band identifier of frequency band 2 and the maximum transmit power allowed when antenna 1 transmits radio frequency signals in frequency band 2, and mapping relationship 3 includes the antenna identifier of antenna 1, the frequency band identifier of frequency band 3 and the maximum transmit power allowed when antenna 1 transmits radio frequency signals in frequency band 3.

[0055] The maximum transmission power may be obtained in advance through testing, and the maximum transmission power is the maximum allowable transmission power that will not cause signal interference to the camera module after testing.

[0056] Step 302: The radio frequency module determines the maximum target transmit power according to each mapping relationship, and reduces the transmit power of the target antenna according to the maximum target transmit power.

[0057] The following is an exemplary introduction to the process of the RF module determining the maximum target transmit power according to various mapping relationships.

[0058] Optionally, for each mapping relationship, the RF module can detect whether the antenna currently used by the RF module to transmit the RF signal matches the antenna identifier included in the mapping relationship, and detect whether the frequency band currently used by the RF module to transmit the RF signal matches the frequency band identifier included in the mapping relationship. That is, the RF module detects whether the antenna identifier of the antenna currently used to transmit the RF signal is consistent with the antenna identifier included in the mapping relationship, and the RF module also detects whether the frequency band identifier of the frequency band currently used to transmit the RF signal is consistent with the frequency band identifier included in the mapping relationship.

[0059] If the antenna identifier is consistent, it means that the antenna used to transmit the RF signal currently matches the antenna identifier included in the mapping relationship. If the frequency band identifier is consistent, it means that the frequency band used to transmit the RF signal currently matches the frequency band identifier included in the mapping relationship. When both the antenna identifier and the frequency band identifier match, the antenna is determined to be the target antenna, and the maximum transmit power included in the mapping relationship is determined as the maximum target transmit power.

[0060] Optionally, the RF module may first match, based on the antenna identifier of the antenna used to transmit the current RF signal, a candidate mapping relationship including the antenna identifier from the obtained various mapping relationships, and then further match, based on the frequency band identifier of the frequency band used to transmit the current RF signal, a target mapping relationship including the frequency band identifier from the candidate mapping relationships, and determine the maximum transmit power included in the target mapping relationship as the maximum target transmit power; or, the RF module may first match, based on the frequency band identifier of the frequency band used to transmit the current RF signal, a candidate mapping relationship including the frequency band identifier from the obtained various mapping relationships, and then further match, based on the antenna identifier of the antenna used to transmit the current RF signal, a target mapping relationship including the antenna identifier from the candidate mapping relationships, and determine the maximum transmit power included in the target mapping relationship as the maximum target transmit power. In this way, by narrowing the range of the mapping relationships through the first matching process and then performing a secondary matching to obtain the target mapping relationship, the matching efficiency can be improved.

[0061] After determining the maximum target transmit power according to the various mapping relationships through the above-described implementation manner, the RF module then reduces the transmit power of the target antenna according to the maximum target transmit power. Exemplarily, the RF module controls the target antenna to transmit the RF signal at the maximum target transmit power. It can be understood that the maximum target transmit power is the maximum allowable transmit power after being restricted to avoid signal interference from the RF module to the camera module.

[0062] In a possible implementation manner, the above steps 301 and 302 may be implemented by a modem in the RF module. Exemplarily, after the RF processor in the RF module receives the interference instruction broadcast by the camera module, the RF processor issues an instruction to limit the transmit power to the modem. The modem then obtains at least one mapping relationship, writes this information into a temporary storage area, and then the modem compares the antenna and frequency band used to transmit the current RF signal according to the various mapping relationships, determines the maximum target transmit power, and sets a limit on the transmit power of the target antenna according to the maximum target transmit power, so as to achieve the purpose of reducing the transmit power of the target antenna.

[0063] In the above embodiment, by controlling the target antenna to transmit the RF signal at the maximum target transmit power, the communication quality can be ensured as much as possible. By reducing the transmit power of the target antenna, signal interference from the RF module to the camera module can be avoided, the problem of the captured image being distorted or frozen can be solved, and the shooting experience can be improved.

[0064] In one embodiment, on the basis of Figure 3 the embodiment shown, refer to Figure 4 , this embodiment introduces the implementation manner of the RF module for obtaining at least one mapping relationship.

[0065] Refer to Figure 4 , step 301 may include Figure 4 Step 401 and step 402 are shown:

[0066] Step 401: The radio frequency module determines the signal type of the radio frequency signal.

[0067] The signal type includes a cellular signal, a Bluetooth signal, or a WIFI (Wireless Fidelity) signal.

[0068] In the embodiment of the present application, the RF signal currently transmitted by the RF module may be a cellular signal, a Bluetooth signal or a WIFI signal. For RF signals of different signal types, there are certain differences in the frequency bands and antennas used.

[0069] In view of this, in the embodiments of the present application, for different signal types, the mapping relationship corresponding to the signal type is preset respectively. For example, for cellular signals, the transmission of cellular signals may use antenna 1, antenna 2 and antenna 3 in the electronic device, wherein the distance between antenna 1 and antenna 2 and the camera module is less than the preset distance threshold, then the mapping relationship between antenna 1 and its corresponding cellular frequency bands and maximum transmission powers is preset, and the mapping relationship between antenna 2 and its corresponding cellular frequency bands and maximum transmission powers is preset.

[0070] Step 402: The radio frequency module obtains mapping relationships corresponding to the signal type according to the signal type.

[0071] In this way, when the RF module obtains at least one mapping relationship, it can first determine the signal type of the currently transmitted RF signal, such as whether the currently transmitted signal is a cellular signal, a Bluetooth signal or a WIFI signal, and then obtain the various mapping relationships corresponding to the signal type based on the signal type.

[0072] In a possible implementation of step 402, the RF module may obtain each mapping relationship from NV (Non-Volatile) data according to the signal type, that is, each mapping relationship is stored in the NV partition in the form of NV data, and the RF module obtains each mapping relationship from the NV partition, and then determines the maximum target transmission power based on each mapping relationship, and then limits the transmission power of the target antenna by means of an interface according to the maximum target transmission power.

[0073] In another possible implementation of step 402, the SAR (Specific Absorption Rate) solution can also be used to limit the maximum transmission power. However, this method cannot limit the transmission power of the SRS (Sounding Reference Signal) signal. Therefore, the SRS signal needs to be limited separately.

[0074] Exemplarily, the RF module can identify whether the currently transmitted RF signal is an SRS signal. When the RF signal is not an SRS signal, the RF module obtains each mapping relationship from the EFS (Extended File System) file according to the signal type, that is, each mapping relationship is stored in the EFS partition in the form of EFS data. The RF module obtains each mapping relationship from the EFS partition, and then determines the maximum target transmission power based on each mapping relationship; when the RF signal is an SRS signal, the RF module still obtains each mapping relationship from the NV data according to the signal type.

[0075] After the RF module obtains the mapping relationships corresponding to the signal type according to the signal type, it can determine the maximum target transmit power according to the mapping relationships, and then reduce the transmit power of the target antenna according to the maximum target transmit power. The implementation method of obtaining the mapping relationship in this embodiment is flexible and diverse, and can be flexibly selected during implementation, which is conducive to improving the implementation flexibility of the embodiment of this application.

[0076] In one embodiment, if the camera module detects a camera exit command, it sends a power recovery command and then exits the working mode. The RF module responds to the power recovery command and increases the transmission power of the target antenna.

[0077] Assuming that the frequency band used by the target antenna when the RF module reduces the transmission power of the target antenna in step 203 is called the target frequency band, after the RF module receives the power recovery instruction, the RF module can read (for example, read from the NV partition) the maximum transmission power corresponding to the target antenna and the target frequency band. It can be understood that the maximum transmission power is the maximum transmission power of the target frequency band supported by the RF module, and the maximum transmission power is greater than the maximum target transmission power after the above power limit. If the target antenna is still transmitting RF signals on the target frequency band at this time, the RF module restores the transmission power of the target antenna according to the maximum transmission power, and if the target antenna is not transmitting RF signals on the target frequency band at this time, the RF module writes the maximum transmission power corresponding to the target antenna and the target frequency band into the temporary storage area, and the next time the target antenna transmits RF signals on the target frequency band, the transmission power of the target antenna is restored according to the maximum transmission power, thereby releasing the transmission power limit corresponding to the target antenna and the target frequency band.

[0078] In this way, the embodiment of the present application promptly restores the transmission power of the target antenna when the camera module exits, thereby ensuring the communication quality.

[0079] In one embodiment, based on Figure 2 The embodiment shown, see Figure 5 , the camera module can be Figure 5Steps 2011 and 2012 shown in the figure implement the process of the camera module detecting whether the power limit condition is met in the working mode. Figure 5 As shown, step 201 includes the following steps:

[0080] Step 2011: The camera module detects whether an interference mark is stored in a preset storage location in the working mode.

[0081] The interference flag is generated when the camera module determines that the RF module has signal interference with the camera module.

[0082] In an embodiment of the present application, the camera module can also detect whether the power limit condition is met during the last preview or shooting process. If the power limit condition is met, the camera module sends an interference command. After the camera module sends the interference command, the RF module reduces the transmission power of the target antenna. The camera module can also detect whether the degree of screen distortion and / or freeze in the captured image is reduced.

[0083] Exemplarily, the camera module can be realized by detecting the bit error rate of the current MIPI communication inside the camera module. If the bit error rate is reduced, that is, the degree of screen distortion and / or jamming is reduced, then it is determined that the screen distortion and / or jamming of the captured picture is caused by the signal interference of the RF module to the camera module. The camera module then generates an interference flag and stores the interference flag in a preset storage location.

[0084] On the contrary, if the degree of screen distortion and / or freezing does not decrease, it means that the screen distortion and / or freezing of the captured image may not be caused by the signal interference of the RF module to the camera module, and the camera module will not generate the interference flag.

[0085] In this way, after the camera module is in the working mode, it can first detect whether the above-mentioned interference mark is stored in the preset storage location.

[0086] Step 2012: If the interference flag is not stored in the preset storage location, the camera module detects whether the power limit condition is met.

[0087] If the interference flag is not stored in the preset storage location, it may be that during the last power control process, the camera module determined that the screen distortion and / or freeze of the shooting picture was not caused by the signal interference of the RF module to the camera module, so the camera module re-detects whether the power limit condition is met. Of course, if the interference flag is not stored in the preset storage location, it may also be that the current power control process is the first power control process.

[0088] Regarding the implementation method of the camera module detecting whether the power limitation condition is met, reference may be made to the relevant description in the above embodiments, which will not be repeated here.

[0089] When the camera module detects that the power limit condition is met, the camera module sends an interference instruction, and the radio frequency module responds to the interference instruction to reduce the transmission power of the radio frequency signal currently transmitted by the target antenna in the electronic device.

[0090] Please continue to see Figure 5 The power control method of the embodiment of the present application also includes Figure 5 Step 501 shown:

[0091] Step 501: If an interference flag is stored in the preset storage location, the camera module sends an interference instruction.

[0092] If the interference flag is stored in the preset storage location, the camera module no longer needs to detect whether the power limit condition is met, but directly sends an interference instruction. The frequency module responds to the interference instruction and directly reduces the transmission power of the RF signal currently transmitted by the target antenna in the electronic device.

[0093] In this way, after the camera module reads the interference flag from the preset storage location, it directly sends an interference instruction, which can avoid screen distortion and / or freezes in the shooting picture during the process of the camera module detecting whether the power limit conditions are met, further improving the shooting quality of the camera module.

[0094] In one embodiment, if the interference flag is not stored in the above preset storage location, please continue to refer to Figure 5 In the embodiment of the present application, after step 202, the following steps are also included: Figure 5 Step 502 and step 503 shown:

[0095] Step 502: The camera module detects whether the degree of screen distortion and / or freeze of the captured image is reduced.

[0096] As described above, the camera module can determine whether the degree of screen distortion and / or freeze of the captured image is reduced by detecting the bit error rate of the current MIPI communication within the camera module.

[0097] Step 503: If the degree of screen distortion and / or freeze is reduced, the camera module generates an interference flag and stores the interference flag in a preset storage location.

[0098] If the degree of screen distortion and / or jamming is reduced, it is determined that the screen distortion and / or jamming of the captured image is caused by the signal interference of the RF module to the camera module. The camera module generates an interference flag and stores the interference flag in a preset storage location. The next time the camera module is working, it can directly send an interference instruction according to the interference flag. The frequency module responds to the interference instruction and directly reduces the transmission power of the RF signal currently transmitted by the target antenna in the electronic device, thereby avoiding screen distortion and / or jamming in the captured image during the process of the camera module detecting whether the power limit condition is met, and further improving the shooting quality of the camera module.

[0099] In one embodiment, a power control method is provided for an electronic device, the electronic device including a camera module and a radio frequency module, the method comprising:

[0100] Step A1: The camera module is in working mode and detects whether an interference mark is stored in a preset storage location.

[0101] The interference flag is generated when the camera module determines that the RF module has signal interference with the camera module.

[0102] Step A2: If the interference flag is not stored in the preset storage location, the camera module detects whether the power limit condition is met.

[0103] The power limit condition is used to indicate that the captured image of the camera module has screen distortion and / or freeze.

[0104] Step A3: If the power limit condition is met, the camera module sends an interference instruction.

[0105] In step A4, if an interference flag is stored in the preset storage location, the camera module sends an interference instruction.

[0106] Step A5: The RF module receives the interference instruction, and determines the signal type of the currently transmitted RF signal.

[0107] The signal type includes a cellular signal, a Bluetooth signal or a WIFI signal.

[0108] In step A6, the RF module obtains each mapping relationship from the NV data according to the signal type; or, when the RF signal is not an SRS signal, the RF module obtains each mapping relationship from the EFS file according to the signal type; when the RF signal is an SRS signal, the RF module obtains each mapping relationship from the NV data according to the signal type.

[0109] The mapping relationship includes a correspondence between an antenna identifier, a frequency band identifier, and a maximum transmit power, and the distance between the antenna corresponding to the antenna identifier and the camera module is less than a preset distance threshold.

[0110] Step A7, for each mapping relationship, the RF module detects whether the antenna currently used to transmit the RF signal matches the antenna identifier included in the mapping relationship, and whether the frequency band currently used to transmit the RF signal matches the frequency band identifier included in the mapping relationship.

[0111] Step A8: If the antenna currently used to transmit the RF signal matches the antenna identifier, and the frequency band currently used to transmit the RF signal matches the frequency band identifier, the antenna is determined to be the target antenna, and the maximum transmit power included in the mapping relationship is determined as the maximum target transmit power.

[0112] Step A9: The RF module reduces the transmit power of the target antenna according to the maximum target transmit power.

[0113] Step A10: If the camera module detects a camera exit command, it sends a power recovery command.

[0114] Step A11: The RF module increases the transmission power of the target antenna in response to the power recovery instruction.

[0115] Among them, after step A3, the camera module can also detect whether the degree of screen distortion and / or jamming of the captured image is reduced. If the degree of screen distortion and / or jamming is reduced, the camera module generates an interference flag and stores the interference flag in a preset storage location.

[0116] The following is an example to illustrate the effect of the embodiment of the present application on improving the shooting quality of the camera module.

[0117] See also Figure 1 and Figure 6 , taking the electronic device as a smartphone as an example, the ANT10 in the smartphone (such as Figure 1 The antenna 101 shown is currently registered in the N78 frequency band, and the transmission power of ANT10 is 27dbm.

[0118] The camera module of the smartphone detects that the picture taken by the camera module has a distorted screen (see Figure 6 The camera module sends an interference command. After receiving the interference command, the RF module of the smartphone obtains the mapping relationships from the NV data and finally determines that the maximum target transmission power corresponding to the ANT10 and N78 frequency bands is 20dbm based on the mapping relationships. The RF module limits the transmission power of ANT10 to 20dbm.

[0119] After the transmission power of ANT10 is reduced, the signal interference of the RF module to the camera module is eliminated, so that the camera module can shoot normally, and the screen noise phenomenon of the shooting picture is significantly improved (see Figure 6 (Example of shooting screen on the right in center).

[0120] When the camera module detects a camera exit command (such as a user trigger), the camera module sends a power recovery command. After the RF module receives the power recovery command, the RF module reads the maximum transmit power of 33dbm corresponding to the ANT10 and N78 bands from the NV partition, and the RF module takes effect on the 33dbm value, thereby restoring the transmit power corresponding to the ANT10 and N78 bands to 27dbm before the power reduction (of course, it can also be greater than 27dbm, but it needs to be less than or equal to 33dbm).

[0121] The embodiment of the present application can avoid the problem of the camera module being interfered with by the signal of the RF module. After the camera module is exited, the power limit of the target antenna is promptly released, thereby effectively ensuring the normal communication function of the target antenna and improving the shooting and communication experience of the electronic device.
