Of course, if the first working power is greater than the first preset threshold, it means that the MIPI signal is stronger. 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 furthermore, a certain amount of interference will be caused between the MIPI of the camera and the RF signal.

It can be seen that through the embodiment of the present application, when the camera of the electronic device works at the first MIPI frequency, the radio frequency band of the registered channel is obtained, and the radio frequency band and the first preset interference frequency point set corresponding to the first MIPI frequency When there is an intersection, the first MIPI frequency is switched to the second MIPI frequency, and there is no intersection between the second preset interference frequency point set corresponding to the second MIPI frequency and the radio frequency band, and the radio frequency band and the first preset interference frequency point When there is no intersection between the sets, keep the first MIPI frequency.

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

Wherein, if the interference signal corresponding to the radio frequency band does not exist, it means that the original interference has disappeared and will not cause interference to communication, and furthermore, the second MIPI frequency may be switched to the first MIPI frequency.

It can be seen that through the embodiment of the present application, when the camera of the electronic device works at the first MIPI frequency, the radio frequency band of the registered channel is obtained, and the radio frequency band and the first preset interference frequency point set corresponding to the first MIPI frequency When there is an intersection, the first MIPI frequency is switched to the second MIPI frequency, and there is no intersection between the second preset interference frequency point set corresponding to the second MIPI frequency and the radio frequency band, and the radio frequency band and the first preset interference frequency point When there is no intersection between the sets, the first MIPI frequency is maintained, and when the interference signal corresponding to the radio frequency band does not exist, the second MIPI frequency is switched to the first MIPI frequency.
