In this embodiment, at least a portion of the signal receiving module 30 is electrically connected to the circuit board 11 and is spaced from the image sensing component 12, so that the installation space inside the electronic device can be reasonably utilized, the arrangement between the signal receiving module 30 and the camera module 10 is tighter, the accuracy of the signal strength test of the received radio frequency signal is further improved, and the image quality photographed by the electronic device is further improved.

For example, the receiving antenna 31 and the image sensing element 12 may be provided at a pitch of 0.1 mm to 3 mm on the circuit board 11, and so on.
In some embodiments, the distance between the receiving antenna 31 and the image sensing component 12 on the circuit board 11 is greater than or equal to 0.25 mm and less than or equal to 1 mm.
In this embodiment, the distance between the receiving antenna 31 and the camera module 10 on the circuit board 11 is greater than or equal to 0.25 mm and less than or equal to 1 mm, so that the distance between the receiving antenna 31 and the envisaged module is reasonable, the accuracy of the detected signal intensity can be ensured, and the interference of the receiving antenna 31 on the camera module 10 can be ensured.

Specifically, the distance between the receiving antenna 31 and the camera module 10 on the circuit board 11 may be 0.5 mm.
In the case that at least a portion of the signal receiving module 30 is disposed on the circuit board, the signal receiving module 30 is electrically connected to the processor 40 through the circuit board 11, it may be that the receiving antenna 31 of the signal receiving module 30 is electrically connected to a pin of the circuit board 11, the pin of the circuit board 11 is electrically connected to the processor 40, and the rf signal receiving and amplifying unit 32 may be electrically connected between the pin of the circuit board 11 and the processor 40.

In this way, the arrangement of the receiving antenna 31 can be made more flexible.
In the embodiment of the present application, in the case that the electronic device further includes the rf module 20, the signal receiving module 30 may receive the rf signal at a partial frequency division point of the operating frequency band of the rf module 20.
In some embodiments, the operating frequency band of the signal receiving module 30 covers the operating frequency band of the rf module 20. In this way, the signal receiving module 30 can receive all the rf signals on the operating frequency band of the rf module 20, so as to improve the shooting quality of the camera module 10 when the rf signals generated by the rf module 20 at any frequency point interfere with the camera module 10.
In the embodiment of the present application, the processor 40 may be configured to obtain the signal strength of the radio frequency signal received by the signal receiving module 30, determine whether the image capturing module 10 is interfered by the radio frequency signal based on the signal strength, and adjust the target parameter under the condition that the image capturing module 10 is interfered by the radio frequency signal, so as to improve the image quality of the image data.
The processor 40 may be a central processor of an electronic device, or may be other control devices other than the central processor 40, which is not limited herein.
The signal strength of the rf signal received by the signal receiving module 30 may be obtained by analyzing the received rf signal to obtain information such as a frequency point and a signal strength of the rf signal when the processor 40 receives the rf signal transmitted by the signal receiving module 30.
The above-mentioned determining whether the image capturing module 10 is interfered by the radio frequency signal based on the signal strength, after the above-mentioned processor 40 obtains the signal strength, the processor 40 may compare the signal strength with a preset signal threshold to determine whether the signal strength is greater than or equal to the preset signal threshold, further determine whether the image quality of the image data of the image capturing module 10 meets the image quality requirement if the signal strength is greater than or equal to the preset signal threshold, and determine that the image capturing module 10 is interfered by the radio frequency signal if the image quality of the image data does not meet the image quality requirement; and the signal intensity is smaller than the preset signal threshold, or the signal intensity is larger than or equal to the preset signal threshold, and the image quality of the image data meets the image quality requirement, it is determined that the camera module 10 is not interfered by the radio frequency signal.
It should be noted that, in the case that the signal receiving module may simultaneously receive a plurality of radio frequency signals with different frequency points, the preset signal thresholds compared with the signal strengths of the different radio frequency signals may be the same or different, which is not limited herein.
The preset signal threshold may be a value set in advance in the electronic device according to actual needs, and for example, it may be a signal strength set empirically by a user.
Or may receive the radio frequency signal input by the signal receiving module 30 of the electronic device when the camera module 10 is in an operating state; if the image quality of the image data of the camera module 10 is detected to be not meeting the image quality requirement under the condition that the radio frequency signal is in the adjusted state, determining the signal strength of the radio frequency signal as the preset signal threshold. In this way, by determining the signal strength of the radio frequency signal as the preset signal threshold when the image quality of the image data of the image capturing module 10 does not meet the image quality requirement in the adjusted state, the preset signal threshold is set more reasonably.
The above determination of whether the image quality of the image data of the image capturing module 10 meets the image quality requirement may be that the processor 40 obtains an image quality evaluation parameter of the image data, compares the image quality evaluation parameter with a preset quality evaluation parameter, and determines whether the image quality of the image data meets the image quality requirement according to the comparison result.
The image quality evaluation parameter may be any parameter value of an evaluation index that can be used to evaluate the image quality of the image data. For example, the image quality evaluation parameter may include at least one of resolution, packet loss rate, and bit error rate.
Specifically, the comparing the image quality evaluation parameter with the preset quality evaluation parameter, and determining whether the image quality of the image data meets the image quality requirement according to the comparison result may be obtaining the error rate of the image data of the camera module 10; under the condition that the obtained error rate is greater than or equal to the preset error rate, it is determined that the image quality of the image data of the camera module 10 does not meet the image quality requirement, so that whether the image quality of the image data of the camera module 10 meets the image quality requirement can be determined according to a comparison result of the error rate and the preset error rate, and the determination mode is simpler and more accurate.
And in the case that the obtained error rate is smaller than the preset error rate, the processor 40 may determine that the image quality of the image data satisfies the image quality requirement.
Whether the image quality of the image data of the camera module 10 meets the image quality requirement or not can be obtained by comparing the resolution or the packet loss rate with the corresponding preset threshold, which is not described herein.
In the embodiment of the present application, the processor 40 may adjust at least one of the data transmission rate of the camera module 10 and the transmitting power of the rf signal to improve the image quality of the image data when determining that the camera module is interfered by the rf signal.
Specifically, the processor 40 may adjust only the data transmission rate increase in the image data transmitted by the image capturing module 10; alternatively, the processor 40 may only adjust the signal power of the rf signal generated by the rf module 20 to decrease, so as to decrease the signal strength of the rf signal; alternatively, the processor 40 may adjust both the reduction of the signal power of the rf signal generated by the rf module 20 and the increase of the data transmission rate of the image capturing module 10 for transmitting the image data.
In some embodiments, the adjusting the target parameter by the processor 40 may include: in the case that the camera module 10 is determined to be interfered by the radio frequency signal based on the signal strength, the processor 40 adjusts the data transmission rate of the camera module 10; in the case that the image quality of the image data satisfies the image quality requirement during the adjustment process and the adjusted data transmission rate does not reach the maximum data transmission rate, the processor 40 stops adjusting the data transmission rate of the camera module 10; or in the case that the data transmission rate of the camera module 10 is adjusted to the maximum data transmission rate and the image quality of the image data of the camera module 10 does not meet the image quality requirement, the processor 40 stops adjusting the data transmission rate of the camera module 10 and continues to adjust the signal strength of the radio frequency signal.
Therefore, the electronic device can adjust the data transmission rate of the camera module 10 first, and adjust the signal strength of the radio frequency signal under the condition that the data transmission rate of the camera module 10 is adjusted to the maximum data transmission rate, so that the communication quality of the electronic device can be prevented from being reduced.
In the case where the radio frequency signal is transmitted by another electronic device, the adjusting the transmission power of the radio frequency signal may be that the electronic device transmits a signal adjustment request to the other electronic device, and the other electronic device adjusts the transmission power of the radio frequency signal based on the signal adjustment request.
The processor 40 adjusts the signal strength of the rf signal, and may include: the processor 40 successively adjusts the signal intensity of the radio frequency signal to be reduced according to a preset adjustment range until the image quality of the image data of the camera module 10 meets the image quality requirement; or reducing the transmitting power of the radio frequency signal to a target transmitting power, wherein the image quality of the image data of the camera module 10 meets the image quality requirement, and the signal strength of the radio frequency signal is a preset signal strength threshold value under the target transmitting power, so that the adjustment modes are flexible and various.
Fig. 4 is a flowchart of a control method of an electronic device according to an embodiment of the present application. The control method of the electronic device is applied to the electronic device shown in fig. 1 to 3. As described above with reference to fig. 4, the control method of the electronic device at least includes the following steps 401 and 402.
Step 401, acquiring the signal intensity of a radio frequency signal received by a signal receiving module of the electronic equipment under the condition that a camera module of the electronic equipment is in a working state;
step 402, adjusting a target parameter to improve the image quality of the image data under the condition that the camera module is interfered by the radio frequency signal based on the signal strength, wherein the target parameter includes the data transmission rate of the camera module and/or the transmitting power of the radio frequency signal.
In some embodiments, the adjusting the target parameter when the camera module is determined to be interfered by the radio frequency signal based on the signal strength includes:
