Abstract: Systems and methods for characterizing a camera system on a mobile device are disclosed. Characterization of the camera system may be implemented by providing a diffraction pattern of dots at controlled, defined angles to the camera system. Images of the diffraction pattern may be captured during a focus sweep through predetermined focus positions and/or while changing the relative locations between the lens and image sensor at the predetermined focus positions. The captured images may be analyzed to determine calibration data that provides physical measurement of properties of the camera system. The calibration data may then be implemented by the camera system to produce enhanced imaging on the mobile device.

Abstract: Various embodiments include implementing optical image stabilization (OIS) in a camera module. For example, a controller may control an actuator of the camera module to move a lens group and/or an image sensor of the camera module to provide OIS movement. In various embodiments, OIS movement control is implemented according to a region-based blur reduction model that effects a greater reduction in blur associated with a target region of an image sensor, relative to one or more other regions of the image sensor.
