摘要： Various embodiments disclosed herein include techniques for maintaining multiple cameras in focus on same objects and/or at same distances. In some examples, a subordinate camera may be configured to focus based on the focus of a primary camera. For instance, a focus relationship between the primary camera and the subordinate camera may be determined. The focus relationship may characterize the trajectory of the lens position of the subordinate camera with respect to the lens position of the primary camera. In various examples, the focus relationship may be updated.

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： A camera system may include one or more controllers to perform in-field monitoring of autofocus performance and instability mitigation. The controllers may monitor one or more parameters associated with adjustment of a relative position between a lens group and an image sensor and/or one or more images. The controllers may analyze the parameters and/or images to calculate various metrics. The controllers may evaluate the metrics with respect to corresponding thresholds. The controllers may detect, based at least in part of the evaluation the metrics, one or more instability events associated with controller performance degradation. In response to detecting the instability events, the controllers may perform one or more remedial actions to mitigate the controller performance degradation.
