摘要： In some embodiments, a plurality of images is captured through an image sensor of a camera during a period of time. The plurality of images is registered to calculate an image-sensor-based measure of movement of the camera during the period of time. The image-sensor-based measure of movement is compared to a motion-sensor-based measure of movement of the camera during the period of time, and a systematic offset between the motion-sensor-based measure of movement and the image-sensor-based measure of movement is calculated.

摘要： Methods and apparatus are disclosed for selecting a lens control mode for a camera in external magnetic fields or other types of non-magnetic interference. In embodiments, when the camera is activated, a test of a position sensor for the camera lens is performed by moving the camera lens through a range of positions and collecting values from the sensor. In embodiments, the sensor readings are analyzed to determine conditions such as (a) whether the sensor is saturated by an external magnetic field or non-magnetic interference, (b) whether the sensor's readings are within an error margin, and (c) whether a computed position offset for the sensor is valid. Based on the analysis, the camera is placed into a first control mode where movement of the lens is controlled using the position sensor, or a second control mode where lens movement is controlled without the position sensor.

摘要： An actuator module which includes a Hall sensor, configured to generate output signals indicating a displacement of a mobile component by a Lorentz actuator mechanism, can be calibrated to remove corruption of the output signals due to magnetic fields generated by a coil assembly of the actuator mechanism. Such calibration can include tracking and manipulating one or more of current strength, output signal voltage strength, and mobile component displacement to establish a relationship between output signal voltage and current applied to the coil assembly. The relationship can be used to generate, for a given generated output signal voltage and applied current strength, an offset signal voltage which can be subtracted from the voltage strength of the output signal to determine a corrected output signal, independent of coil assembly corruption, which indicates a displacement of the mobile component.
