Abstract: Devices, methods, and non-transitory computer readable media are disclosed herein to correct for unwanted rotation in an embedded camera module of an electronic device during field use. Various rotation calibration techniques are disclosed herein, including: a reference pixel pattern-based rotation calibration process; a magnetic field sensor-based rotation calibration process; and a gimbal lock-based rotation calibration process. In some embodiments, an initial rotation calibration angle for the camera module may be obtained during factory calibration and used by the electronic device's image signal processing (ISP) pipeline, so that all captured images are automatically rotation-corrected to compensate for any such rotation measured during factory calibration. In some embodiments, a rotation correction operation may be triggered in response to the electronic device detecting a reliability event (e.g., shock, fall, repair) during field use, which rotation correction operation may be used to update or overwrite the initial rotation calibration angle for the camera module.

Abstract: Various embodiments disclosed herein include techniques for adjusting the lateral position of a default field of view of a camera. The camera may change the lateral position of its field of view by creating relative movement between an image sensor and a lens of the camera, and may maintain the camera's field of view to the default field of view when the camera is stationary. In some embodiments, the lateral position may be set using orientation information associated with the camera. In other embodiments, the lateral position may be set using position information associated with a target object.
