Abstract

The invention discloses an electromagnetic interference control method and a related product. The method comprises the following steps: enabling a Video function of a camera, obtaining a first workingfrequency of the camera, obtaining a second working frequency of the antenna; if the second working frequency is interfered, Obtaining a target frame rate range; according to a preset mapping relation between the working frequency of the camera and the frame rate of the camera, determining the working frequency of a camera corresponding to each frame rate in the target frame rate range; enablingthe working frequencies of the cameras corresponding to all the frame rates to form a working frequency list; determining at least one third working frequency of which the interference on the second working frequency is smaller than the first working frequency from the working frequency list, and selecting one third working frequency from the at least one third working frequency as a first targetworking frequency, determining a target frame rate, and realizing a video function by using the first target working frequency and the first target frame rate, so that when the video function is realized, the interference of the frame rate on the antenna is reduced.

Description

technical field

[0001] This application relates to the field of electronic technology, in particular to an electromagnetic interference control method and related products. Background technique

[0002] With the development of mobile communication technology, users have an increasing demand for communication with mobile phones and other electronic devices. At present, when electronic devices on the market transmit data, they generally transmit data through cellular mobile network communication or Wi-Fi communication. , All full-screen mobile phones are facing radio frequency interference problems. For example, when electronic devices are shooting video or video chatting, the frame rate of the camera is required to be high, and the realization of the frame rate of the camera will interfere with the radio frequency signal of the antenna to a certain extent.

[0003] At present, the interference to each module can be improved through hardware upgrades, but the cost will be incr...
