In this way, different PCLK frequencies can be implemented to realize imaging in different photographing modes. The above-mentioned target photographing mode may be the current photographing mode.

Optionally, N MCLK frequencies are pre-stored in the electronic device, and N is a positive integer greater than 1; in the above step 102, switching the first MCLK frequency to the second MCLK frequency may include the following steps:

21. Determine an interfering radio frequency channel, where the radio frequency band includes the interfering radio frequency channel;

22. Screening MCLK frequencies with an interference degree less than a preset interference threshold from the N MCLK frequencies according to the interfering radio frequency channel, to obtain M MCLK frequencies, where M is a positive integer less than or equal to the N;

23. Use one MCLK frequency among the M MCLK frequencies as the second MCLK frequency, and switch the first MCLK frequency to the second MCLK frequency.

The above-mentioned interference radio frequency channel may be a radio frequency channel corresponding to the interference signal, and the above-mentioned preset interference threshold may be set by the user or the system defaults. The electronic device can store N MCLK frequencies in advance, where N is an integer greater than 1. Each of the N MCLK frequencies can correspond to an interference degree of the interfering radio frequency channel, and further, the interference degree can be selected from the N MCLK frequencies less than the preset interference. The MCLK frequency of the threshold is obtained to obtain M MCLK frequencies, where M is a positive integer not greater than N, and then, one MCLK frequency can be selected from the M MCLK frequencies as the second MCLK frequency, and then the first MCLK frequency is switched to the second MCLK frequency MCLK frequency. Optionally, the second MCLK frequency may be the one closest to the first MCLK frequency among the M MCLK frequencies.

The strength of the interference corresponding to the interfering radio frequency channel is determined by the working power of the corresponding hardware. Further, if the working power is large, the interference is large, and if the working power is small, the interference is small. Furthermore, a preset working power threshold can be preset. , when the working power is greater than the preset working power threshold, execute the step of switching the first MCLK frequency to the second MCLK frequency, and when the working power is less than or equal to the preset working power threshold, do not execute the step of switching the first MCLK frequency to the second MCLK frequency The step of switching the first MCLK frequency to the second MCLK frequency is described.

103. When there is no intersection between the radio frequency band and the first preset interference frequency point set, maintain the first MCLK frequency.

Wherein, if there is no intersection between the radio frequency band and the first preset interference frequency point set, it means that there is no interference between the first MCLK frequency and the RF radio frequency, and the first MCLK frequency can be maintained.

As an example, an anti-interference method is proposed based on the above-mentioned application, that is, the MCLK frequencies of two groups of cameras are preset in the electronic device, that is, the first MCLK frequency A and the second MCLK frequency B. Calculate the RF frequency band and the corresponding channel that may be interfered. For example, it can expand the existing 6 cellular mobile systems: GSM, WCDMA, TDSCDMA, TDD-LTE, FDD-LTE, CDMA, and preset it as a switching condition to In electronic equipment, if frequency A interferes with RF frequency band 1 and does not interfere with other RF frequency bands, and frequency B interferes with RF frequency band 2 and does not interfere with other RF frequency bands, when the registered channel reported by the adjustment and demodulator MODEM of the electronic equipment is the interference of frequency A When the camera is operating at frequency A and the RF frequency is at frequency 1, the frequency A is changed to frequency B. When the RF frequency is not at frequency 1, the MCLK frequency remains at frequency A, which can save costs and improve user experience.

Optionally, in the above step 102, switching the first MCLK frequency to the second MCLK frequency may further include the following steps:

Obtain the first working power corresponding to the first MCLK frequency; obtain the second working power corresponding to the radio frequency band; when the first working power is greater than the first preset threshold and the second working power is greater than the second preset When the threshold is set, the step of switching the first MCLK frequency to the second MCLK frequency is performed.

The first preset threshold and the second preset threshold can be set by the user, or the system defaults. Of course, when the first working power is greater than the first preset threshold, it means that the MCLK signal is strong, and the second preset threshold is strong. When the working power is greater than the second preset threshold, it means that the signal corresponding to the radio frequency band is strong, and further, certain interference will be caused between the MCLK of the camera and the RF signal.

It can be seen that, according to the embodiment of the present application, when the camera of the electronic device operates at the first MCLK frequency, the radio frequency frequency band of the registered channel is obtained, which is between the radio frequency frequency band and the first preset interference frequency point set corresponding to the first MCLK frequency. When there is an intersection, switch the first MCLK frequency to the second MCLK frequency, there is no intersection between the second preset interference frequency point set corresponding to the second MCLK frequency and the radio frequency band, and the radio frequency band and the first preset interference frequency point When there is no intersection between sets, the first MCLK frequency is maintained. In this way, if the MCLK of the camera of the electronic device is working, if it is interfered by RF, the MCLK frequency of the camera can be switched, which can reduce the MCLK of the camera and the RF radio frequency. interference, improve the communication quality of users, and have the advantage of high user experience.

Consistent with the above, please refer to FIG. 2 , which is a schematic flowchart of an embodiment of an anti-interference method for an electronic device provided by an embodiment of the present application.

201. When the camera of the electronic device operates at the first MCLK frequency, acquire the radio frequency band of the registered channel.

202. When there is an intersection between the radio frequency band and the first preset interference frequency point set corresponding to the first MCLK frequency, switch the first MCLK frequency to a second MCLK frequency, and the second MCLK frequency There is no intersection between the corresponding second preset interference frequency point set and the radio frequency band.

203. When there is no intersection between the radio frequency band and the first preset interference frequency point set, maintain the first MCLK frequency.

For the specific description of the above steps 201 to 203, reference may be made to the anti-interference method of the electronic device described in FIG. 1 , and details are not repeated here.

204. When the interference signal corresponding to the radio frequency band does not exist, switch the second MCLK frequency to the first MCLK frequency.

Wherein, if the interference signal corresponding to the radio frequency band does not exist, it means that the original interference disappears and will not interfere with the communication, and further, the second MCLK frequency can be switched to the first MCLK frequency.

It can be seen that, through the embodiment of the present application, when the camera of the electronic device operates at the first MCLK frequency, the radio frequency frequency band of the registered channel is obtained, which is between the radio frequency frequency band and the first preset interference frequency point set corresponding to the first MCLK frequency.
