Problems solved by technology

[0002] In daily life, when the camera of the electronic device and the radio frequency system work at the same time, the operating frequency of certain frequency bands of the radio frequency system may cause electromagnetic interference to the camera, resulting in blurred screen or freeze phenomenon when the camera previews and takes pictures.
In the prior art, the shielding protection is added to the camera signal transmission line to reduce the electromagnetic interference of the radio frequency system to the camera. However, this method of improving the hardware will increase the cost of the electronic equipment and increase the volume of the electronic equipment, which is not enough flexible and intelligent

Abstract

The embodiment of the invention discloses an electromagnetic interference control method and a related apparatus. The method comprises the following steps: when it is detected that a camera of an electronic device is opened, detecting whether the camera generates electromagnetic interference with a radio frequency system of the electronic device; if so, determining a currently enabled first antenna, and detecting whether the first antenna is an antenna farthest from the camera; if not, sending a first preset instruction to a Modem through an AP; and receiving the first preset instruction through the Modem, performing an antenna switching operation to reduce or avoid the electromagnetic interference between the camera and the radio frequency system. The electromagnetic interference controlmethod disclosed by the embodiment of the invention is advantageous for reducing or avoiding the electromagnetic interference.

Description

technical field [0001] The present application relates to the technical field of electronic equipment, and in particular to an electromagnetic interference control method and a related device. Background technique [0002] In daily life, when the camera of the electronic device and the radio frequency system work at the same time, the operating frequency of certain frequency bands of the radio frequency system may cause electromagnetic interference to the camera, resulting in blurred screen or freeze phenomenon when the camera previews and takes pictures. In the prior art, the shielding protection is added to the camera signal transmission line to reduce the electromagnetic interference of the radio frequency system to the camera. However, this method of improving the hardware will increase the cost of the electronic equipment and increase the volume of the electronic equipment, which is not enough Flexible and smart.
