Abstract:
At a processor of a camera-equipped electronic device, a first data set generated at a sensor incorporated within a camera module is obtained, and a second data set generated at one or more sensors external to the camera module is obtained. Based on the first set and second data sets, a first set of control signals is transmitted to the camera module. At a disturbance rejection controller integrated within the camera module, a second set of control signals is generated, based on the first set of control signals and on a third set of data obtained from the sensor incorporated within the camera module. The second set of control signals is transmitted to an actuator, which causes a displacement of a camera lens.
