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.

Abstract: 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.

Abstract: Various embodiments disclosed herein include techniques for operating a multiple camera system. In some embodiments, a primary camera may be selected from a plurality of cameras using object distance estimates, distance error information, and minimum object distances for some or all of the plurality of cameras. In other embodiments, a camera may be configured to use defocus information to obtain an object distance estimate to a target object closer than a minimum object distance of the camera. This object distance estimate may be used to assist in focusing another camera of the multi-camera system.

Abstract: Various embodiments include camera movement control for reduced power consumption. Some embodiments, for example, may include operating a camera module in a power saving mode, in which focus movement control may be synchronized with frame capture. According to some examples, such synchronization may include holding a position (e.g., a focus position) of a lens group and/or an image sensor of the camera module during some integration time periods. Furthermore, such synchronization may include enabling power saving movement (e.g., between a focus position and a neutral position) of the lens group and/or the image sensor during some other time periods, such as during intervals (e.g., blanking intervals) between integration time periods, and/or during integration time periods for image frames that are expendable.
