Abstract: 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.

Abstract: A camera module with sticky epoxy and method for dislodging particles from a corresponding IR filter. Particles, formed during manufacture or use of the camera, may accumulate in the camera (e.g., on an infrared filter) causing blemishes in camera images. A sticky epoxy with characteristics for attracting and capturing particles is located in the camera. The epoxy may be located in a gap between a substrate and an outside edge of an infrared filter coupled to the substrate. The epoxy and the gap may surround the infrared filter and the epoxy may also be located on other surfaces of the camera. A process for loosening particles from the infrared filter includes driving an actuator that moves the substrate/infrared filter assembly (perhaps striking a base assembly) to loosen the particles from the infrared filter such that the particles are moved to, and trapped by, the epoxy.
