US Patent 10930126 Motion sensing for electronic devices

This application is directed to an electronic device that uses at least a low-power computer vision component to determine whether to activate a camera. For instance, the electronic device may cause the camera to operate in a low-power mode, such as by turning the camera off. The electronic device may then detect motion of an object using a motion sensor. Additionally, the electronic device may generate first image data using the computer vision component, where the first image data represents the object. After generating the first image data, the electronic device may use the computer vision component to analyze the first the image data in order to determine that the object includes a type of object, such as a person. Based at least in part on the determination, the electronic device may activate the camera and generate second image data using the camera.
