  • Patent number: 11570348
    Abstract: Disclosed are an electromagnetic interference control method and a related product. The method is for an electronic device including an antenna and a camera. The method includes: obtaining a first operating frequency of the camera and a second operating frequency of the antenna; determining the second operating frequency is interfered; in response to the second operating frequency being interfered, obtaining a target frame rate range; determining an operating frequency of the camera corresponding to each frame rate in the target frame rate range; obtaining an operating frequency list; determining at least one third operating frequency from the operating frequency list; and selecting one third operating frequency from the at least one third operating frequency as a first target operating frequency; determining a first target frame rate; operating the camera at the first target operating frequency; and performing the video function based on the first target frame rate.

  • Patent number: 11165937
    Abstract: Disclosed are an electromagnetic interference control method, an electronic device and a non-transitory computer-readable storage medium. The method includes detecting whether a camera of the electronic device is activated, responsive to detecting that the electronic device receives a voice communication service; detecting whether electromagnetic interference occurs between the camera and a radio frequency system of the electronic device, responsive to detecting that the camera is activated; if yes, responsive to determining that the currently activated primary antenna is a first antenna, sending a first preset instruction to a modem by an application processor; and receiving the first preset instruction by the modem for switching the activated antenna from the first antenna to a second antenna and fix. Based on the method, the interference of a radio frequency system on a mobile phone camera is reduced, camera screen crash or jam is reduced, and imaging quality is improved.

  • Publication number: 20210289108
    Abstract: An electromagnetic interference control method and related device are provided. The method includes detecting whether there is an electromagnetic interference between an RF system and a camera in response to detecting that a camera of an electronic device is in a turned-on state; detecting a screen state of the electronic device in response to the detected electromagnetic interference, and determining a dynamic switching policy of the four antennas according to the screen state, wherein the screen state includes a vertical screen state and a horizontal screen state, and the dynamic switching policy includes a detection priority sequence of the four antennas and a switching condition of the four antennas; and detecting a communication quality of at least one antenna not currently-used according to the dynamic switching policy, and performing an antenna switching in response to the communication quality meeting the switching condition.
