摘要： Various embodiments disclosed herein include techniques for determining autofocus for a camera on a mobile device. In some instances, depth imaging is used to assist in determining a focus position for the camera through an autofocus process. For example, a determination of depth may be used to determine a focus position for the camera. In another example, the determination of depth may be used to assist another autofocus process.

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.

摘要： Methods and apparatus for detecting and correcting for lens tilt in cameras. The common mode signal may be derived from autofocus position (AP) sensors and used as a measure of the autofocus position of the lens on the Z axis. The differential mode signal may also be derived from the AP sensor signals. The differential mode signal may indicate that the lens is or is not tilted, and if tilted may indicate the direction and magnitude of the tilt. The differential mode signal may be used to apply a tilt correction transform to image data based on the strength and direction of the signal. The differential mode signal may also be used to translate the lens on an axis orthogonal to the Z axis to partially correct for lens tilt to align the image plane with the photosensor.
