Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to fig. 1, a flowchart of an implementation of a communication control method provided in an embodiment of the present application is shown, where the method may be applied to an electronic device capable of performing data communication and image acquisition, such as a mobile phone and a pad. The technical scheme in the embodiment is mainly used for improving the image quality of the image acquired by the electronic equipment.

Specifically, the method in this embodiment may include the following steps:

step 101: the state of a communication module in the electronic device and the state of a target component in the electronic device are monitored.

Step 102: and judging whether the communication module is in the first operation state and whether the target component is in the started state, if so, executing the step 103, otherwise, continuously executing the step 101, namely, continuously monitoring the state of the communication module and the state of the target component.

The communication module may be a module capable of performing data communication in an electronic device, such as a modem that performs signal transmission using an antenna in a mobile phone. The target component may be a component capable of acquiring an image in the electronic device, such as an image acquisition device like a front camera or a rear camera of a mobile phone.

Specifically, the state of the monitoring communication module in this embodiment may be: whether the communication module is in a first operation state is monitored, wherein the first operation state refers to a state that the communication module carries out signal transmission according to corresponding communication parameters. For example, the first operation state may be a state in which the communication module continuously transmits a signal on the uplink channel through an antenna in the electronic device, such as a state in which the mobile phone continuously maintains a voice call with another terminal, such as a state in which the mobile phone continuously maintains a voice or video call with another terminal through an application program, and such as a state in which the mobile phone continuously establishes a data connection with another terminal and continuously uploads data to another terminal through the data connection, and waits. In this embodiment, the state of the monitoring target component may be: and monitoring whether the target component is in an enabled state, wherein the enabled state refers to a state in which the target component can perform image acquisition after being enabled.

Step 103: and adjusting the communication parameters of the communication module in the first operation state so that the image data acquired by the target component meets the output condition.

In one implementation, in the case that the target component is an image capture device in an electronic device, the output condition may be: the image quality parameter value of the image acquired by the image acquisition device is larger than a preset value. Therefore, in the embodiment, the communication parameter of the communication module in the first operation state is adjusted, so that the image quality parameter value of the image acquired by the image acquisition device is greater than the preset value, and the purpose of improving the image quality of the image output by the image acquisition device is achieved by adjusting the communication parameter of the communication module.

In another implementation, the output condition may be: the image acquired by the image acquisition device does not have a pixel region of the target type. The object type here refers to an area of a single pixel, such as a pixel area of a vertical stripe or horizontal stripe type. Therefore, in the embodiment, the communication parameters of the communication module in the first operating state are adjusted to prevent the image acquired by the image acquisition device from not including the pixel region of the target type, for example, the image does not have vertical stripes, so that the purpose of improving the image quality of the image output by the image acquisition device is achieved by adjusting the communication parameters of the communication module.

Specifically, in this embodiment, the value of the communication parameter of the communication module in the first operation state may be adjusted to be higher or lower, so that the image data acquired by the target component can satisfy the output condition. The specific adjustment mode corresponds to the value of the communication parameter and the output condition.

It can be seen from the foregoing technical solutions that, in the communication control method provided in the first embodiment of the present application, by monitoring the states of the communication module and the target component in the electronic device, when the communication module is in the first operating state and the target component is in the enabled state, the communication parameter of the communication module in the first operating state is adjusted, so that the image data acquired by the target component meets the output condition. Therefore, in the embodiment, the situation that the image acquired by the target component does not meet the output condition, such as vertical stripes, is avoided by adjusting the communication parameters of the communication module in the operation, so that the image quality of the image acquired by the target component is improved.

In a specific implementation, the communication module is in the first operating state, and the target component is in the enabled state, which may be in various manners, as follows:

in one case, the communication module first enters a first operational state, such as a state in which the communication module continuously transmits signals on an uplink channel via an antenna in the electronic device, and the target component switches from an unregulated state to a regulated state while the communication module is in the first operational state. For example, in a state where the modem in the mobile phone is talking through the antenna, the state of the front camera in the mobile phone is turned on, as shown in fig. 2.

In another case, the target component is first switched from an unregulated state to a regulated state, and in the case that the target component is in the regulated state, the communication module enters the first operating state from other operating states, where the communication parameters in the other operating states are different from the communication parameters in the first operating state. For example, in the process of opening a rear camera in a mobile phone to record a video, the mobile phone receives an incoming call, and after the incoming call is connected, a modem in the mobile phone communicates with other mobile phones through an antenna, as shown in fig. 3.

In a specific implementation, the communication parameter may be a maximum transmission power of the communication module for signal transmission through the antenna. Based on this, there are several ways to implement the adjustment of the communication parameters:

in one implementation, in step 103, when adjusting the communication parameters of the communication module, the communication module in the first operation state may be controlled to enter the second communication mode from the first communication mode. The communication module under the first communication module controls the antenna to upload signals by using the first transmission power, the communication module controls the antenna to upload signals by using the second transmission power in the second communication mode, the first transmission power and the second transmission power both have maximum transmission power, and the power value of the maximum transmission power of the second transmission power is smaller than that of the maximum transmission power of the first transmission power, that is, the power value of the maximum transmission power in the second communication mode is smaller than that in the first communication mode.

Based on this, in this embodiment, by switching the communication mode of the communication module in the first operation state, the communication module controls the antenna to upload the signal with the lower maximum transmission power, so as to avoid a situation that the image data collected by the target component does not satisfy the output condition when the transmission power exceeds the power value of the maximum transmission power in the second communication mode. For example, taking fig. 2 as an example, in a state that a modem in a mobile phone is in a call through an antenna, if a state of a front camera in the mobile phone is turned on, the modem may cause a preview picture of the front camera output by a screen of the mobile phone to appear in a stripe region by uploading a signal through the antenna, so that the modem limits transmit power of the antenna to upload the signal under a lower maximum transmit power by switching a communication mode of the modem, thereby avoiding a picture stripe situation caused by an excessively high transmit power.

In one implementation, when adjusting the communication parameters of the communication module, step 103 may control the communication module in the first operation state to perform backoff based on a preset power backoff value, so that the maximum transmission power of the communication module is below a preset power interference value. The power back-off value refers to a back-off value of transmission power for controlling an antenna in the electronic device to upload a signal, the power back-off value is related to a power interference value, the power interference value is a maximum power value which can cause image data collected by a target component to be not satisfied with an output condition when the communication module controls the antenna to transmit an uplink signal, and if the maximum transmission power for controlling the antenna to transmit the uplink signal by the communication module exceeds the power interference value, the antenna can generate interference on an image collected by the target component, so that the image is not satisfied with the output condition. Based on this, in this embodiment, the transmission power of the communication module is backed according to the power back-off value, so that the maximum transmission power that can be realized by the communication module is below the power interference value, and the situation that the excessively high transmission power of the communication module interferes with the acquisition of the image data by the target component is avoided. For example, taking fig. 2 as an example, in a state that a modem in a mobile phone is in a call through an antenna, if a state of a front camera in the mobile phone is turned on, the modem uploads a signal through the antenna, which may cause a preview picture of the front camera output by a screen of the mobile phone to appear in a stripe region, so that the modem limits the transmit power of the antenna to upload a signal under a lower maximum transmit power by backing up the transmit power of the modem to limit the maximum transmit power of the modem to be below a power interference value, thereby avoiding a picture stripe condition caused by an excessively high transmit power.

Specifically, the power interference value may be set to 18dBm, and the back-off value may be determined based on pre-factory test data of the electronic device, or the back-off value may be determined according to operation data of the user on the transmission power received after the electronic device is shipped.

In an implementation manner, after step 103, the following steps may also be included in this embodiment, as shown in fig. 4:

step 104: and monitoring whether the target component is recovered to an unregulated state from a regulated starting state, if so, executing the step 105, and if not, returning to executing the step 104, namely, continuously monitoring whether the target component is recovered to the unregulated state.

Specifically, in this embodiment, whether the target component is restored to the unregulated state may be determined by monitoring whether the process corresponding to the target component is ended. For example, it is monitored whether the front camera or the rear camera of the mobile phone is turned off.

Step 105: and recovering the communication parameters of the communication module.

For example, switching the communication module back to the first communication mode or controlling the communication module to resume the transmit power before the backoff.

In one implementation manner, before step 103, the following steps may be further included in this embodiment, as shown in fig. 5:

step 106: the current transmit power of the communication module in the first operational state is obtained.

Specifically, in this embodiment, the current transmission power can be obtained by collecting the transmission power of the communication module in the uplink signal transmission process through the antenna.

Step 107: and judging whether the current transmission power is increased to a preset target power value, if so, executing the step 103, and if not, returning to the step 107, namely, continuously judging whether the current transmission power is increased to the target power value.

Wherein, the target power value can be the minimum transmitting power which can enable the image data collected by the target component not to satisfy the output condition when the communication module carries out uplink signal transmission through the antenna, based on that, when it is monitored that the current transmission power of the communication module reaches the minimum transmission power that makes the image data collected by the target component not satisfy the output condition, i.e. the communication parameters of the communication module, such as switching the communication mode of the communication module or backing off the transmission power of the communication module, etc., and then the transmitting power of the communication module when the uplink signal transmission is carried out through the antenna does not exceed the minimum transmitting power which can enable the image data collected by the target component not to meet the output condition, so that the aim that the image data collected by the target component meets the output condition is fulfilled. For example, in addition to determining whether to adjust the transmit power of the modem by monitoring the state of the modem and the state of the front camera in this embodiment, it may also determine whether to adjust the transmit power of the modem by monitoring whether the current transmit power of the modem reaches a target power value affecting the front camera. Specifically, the transmitting power of the modem in the mobile phone may change due to different network signal coverage states where the mobile phone is located, for example, when the current network signal coverage is good, such as the receiving intensity is higher than-100 dBm, the transmission of the uplink signal of the mobile phone does not need high power, and at this time, the transmitting power of the modem is in a lower state, so that good uplink signal quality can be maintained, and the transmitting power of the modem cannot be automatically raised; under the condition that the current network signal coverage is poor, such as the reception intensity is lower than-100 dBm, in order to maintain good uplink signal quality, the transmission power of the modem is increased in a stepped manner, and when the transmission power of the modem is increased to 18dBm, the uplink signal transmission of the modem through an antenna interferes with an image acquired by a front-facing camera, and stripes and the like occur.

Referring to fig. 6, a schematic structural diagram of a communication control apparatus according to a second embodiment of the present disclosure is provided, where the apparatus may be configured in an electronic device capable of performing data communication and image acquisition, such as a mobile phone and a pad. The technical scheme in the embodiment is mainly used for improving the image quality of the image acquired by the electronic equipment.

Specifically, the apparatus in this embodiment may include the following units:

a state monitoring unit 601, configured to monitor a state of a communication module in an electronic device and a state of a target component in the electronic device, and trigger a parameter adjusting unit if the communication module is in a first operating state and the target component is in a started state;

a parameter adjusting unit 602, configured to adjust a communication parameter of the communication module in the first operating state, so that the image data acquired by the target component satisfies an output condition.

It can be seen from the foregoing technical solutions that, in the communication control apparatus provided in the second embodiment of the present application, by monitoring the states of the communication module and the target component in the electronic device, and then under the condition that the communication module is in the first operating state and the target component is in the enabled state, the communication parameter of the communication module in the first operating state is adjusted, so that the image data acquired by the target component meets the output condition. Therefore, in the embodiment, the situation that the image acquired by the target component does not meet the output condition, such as vertical stripes, is avoided by adjusting the communication parameters of the communication module in the operation, so that the image quality of the image acquired by the target component is improved.

In one implementation, the first operation state is a state in which the communication module continuously transmits a signal on an uplink channel through an antenna in the electronic device.

In one implementation, the communication module is in a first operational state and the target component is in a booted state, including: switching the target component from an unregulated state to a regulated state with the communication module in the first operational state; or, in the case that the target component is in the enabled state, the communication module enters the first operating state from the other operating state; the communication parameters in the other operating states are different from the communication parameters in the first operating state.

In an implementation manner, the parameter adjusting unit 602 is specifically configured to: and controlling the communication module in the first running state to enter a second communication mode from a first communication mode, wherein the power value of the maximum transmitting power in the second communication mode is smaller than that in the first communication mode.

In an implementation manner, the parameter adjusting unit 602 is specifically configured to: controlling the communication module in the first operation state to execute backoff based on a preset power backoff value so that the maximum transmission power of the communication module is below a preset power interference value.

In one implementation, the parameter adjusting unit 602 is further configured to: and if the target component is restored from the enabled state to the non-enabled state, restoring the communication parameters of the communication module.

In one implementation, the apparatus in this embodiment may further include the following units, as shown in fig. 7:

a power obtaining unit 603 configured to: if the communication module is in the first operating state and the target component is in the enabled state, obtaining the current transmission power of the communication module in the first operating state before the parameter adjusting unit 602 adjusts the communication parameters of the communication module in the first operating state; if the current transmission power of the communication module in the first operation state is increased to a preset target power value, triggering a parameter adjustment unit 602 to adjust the communication parameters of the communication module in the first operation state; the target power value is smaller than or equal to a preset power interference value.

In one implementation, the target component is an image capture device; wherein the output condition includes: the image quality parameter of the image acquired by the image acquisition device is greater than a preset value; or, the image acquired by the image acquisition device does not have a pixel region of the target type.

It should be noted that, for the specific implementation of each unit in the present embodiment, reference may be made to the corresponding content in the foregoing, and details are not described here.

Referring to fig. 8, a schematic structural diagram of an electronic device according to a third embodiment of the present disclosure is shown, where the electronic device may be an electronic device capable of performing data communication and image acquisition, such as a mobile phone and a pad. The technical scheme in the embodiment is mainly used for improving the image quality of the image acquired by the electronic equipment.

Specifically, the electronic device in this embodiment may include the following structure:

a communication module 801 such as modem;

a target component 802, such as a front camera or a rear camera;

the processor 803, such as a central processing unit (cpu), is mainly configured to: monitoring the state of the communication module and the state of the target component, and if the communication module is in a first operation state and the target component is in a started state, adjusting the communication parameters of the communication module in the first operation state so that the image data acquired by the target component meets the output condition.

Of course, other components, such as a memory, a touch screen, etc., may also be included in the electronic device.

It can be seen from the foregoing technical solutions that, in the electronic device provided in the third embodiment of the present application, by monitoring the states of the communication module and the target component in the electronic device, when the communication module is in the first operating state and the target component is in the started state, the communication parameter of the communication module in the first operating state is adjusted, so that the image data acquired by the target component meets the output condition. Therefore, in the embodiment, the situation that the image acquired by the target component does not meet the output condition, such as vertical stripes, is avoided by adjusting the communication parameters of the communication module in the operation, so that the image quality of the image acquired by the target component is improved.

Taking a scene that the technical scheme in the application is applicable to a mobile phone as an example, the implementation scheme is explained in detail as follows:

firstly, the problems existing in the current mobile phone are as follows: the distance between the top antenna of the mobile phone and the front camera (referred to as a front camera) is short, for example, the distance between the top antenna of the mobile phone of the Saipan system and the front camera is 0.7mm, so that when the top antenna continuously transmits signals and the front camera is working, vertical stripes appear due to interference of the signals transmitted by the front camera antenna, as shown in fig. 9. Specifically, in the continuous transmission process of the top antenna, the service corresponding to the upper layer of the mobile phone generally includes: services needing continuous data uploading, such as ordinary voice call, VoNR, VoLTE, WeChat video telephony, live broadcast and the like. In any traffic situation, as long as the top antenna continues to transmit, interference may be caused to the operation of the front camera, so that the front camera has vertical stripes.

In order to solve the above problems, according to the technical solution in the present application, there are the following solutions:

during the process of continuously transmitting signals by the top antenna of the mobile phone, the processor recognizes that the front camera is working, and informs the modem accordingly, so that the modem can dynamically control the maximum transmission power limit MTPL (Max Transmit power limit). Based on this, the modem enters a specific power down scenario, namely: the MTPL is reduced to a value that does not interfere with the proactive, i.e., power interference in the context of, for example, 18 dBm. Wherein values that do not interfere with the proactive may be determined from experimental data. For example, experimental data indicate that at a top antenna transmit power of 18dBm, the proactive operation is normal, and at this time the MTPL is reduced to 18 dBm.

If the current network signal is covered well (for example, the receiving intensity is better than-100 dBm), the uplink of the mobile phone does not need high power, namely, the transmitting power cannot be raised to 18dBm, so that the good uplink signal quality can be maintained, and the user service is not influenced completely; if the current network signal coverage is not good (for example, the receiving intensity is worse than-100 dBm), the uplink transmitting power of the mobile phone is gradually increased, but the maximum value can only reach 18dBm, although the tone quality is affected (noise, inaudible and the like) in the voice call process or when data is used, the bit error rate is increased, the uplink rate is affected to a certain extent, but the vertical stripes do not appear on the pre-shot image, as shown in fig. 9, and after the pre-shot is closed, the uplink transmitting power of the mobile phone is recovered, that is, the influence is avoided.

In another specific implementation manner, a condition of proactive state identification may be added in combination with a design logic of a specific Absorption rate SAR (specific Absorption rate), based ON which, the SAR Service in the handset may monitor whether the proactive is in a state of ON-regulated or Off-regulated. When the front camera is turned on, the mobile phone enters a specified SAR scene, for example, a DSI2 scene, and parameters of a radio frequency parameter SAR scene DSI2 are preset in the mobile phone, for example, a backoff value V of the DSI2 scene is set to max. For example, the backoff value required for SAR authentication is denoted by V1, and the backoff value V2 required to solve the proactive interference problem in the present case. Based on this, after the modem switches to the DSI2 scenario, the modem performs a power backoff V, at which time the antenna uplink transmit power does not interfere with the forward shot any more. And when the front camera is closed, the mobile phone exits the DSI2 scene, and then normal SAR design other logics are recovered.
