  • Magnetometer-based lens cap detection
    Patent number: 11215901
    Abstract: A video system includes a camera, at least one magnet providing a magnetic field, a magnetometer, and a processing system. The magnetometer is configured to measure the magnetic field to generate a magnetometer readout. The magnetic field is altered when a lens cap blocks a view of the camera. The processing system is configured to detect, based on the magnetometer readout of the magnetic field, whether the lens cap is blocking the view of the camera.
    Type: Grant
