Abstract: A mobile device uses data from one or more sensors to determine a user context, such as a motion state of the user, and adjusts at least one camera feature selected form a group consisting of continuous auto-focus, auto-white balance, video encode quality, frame rate, search range used for focusing, and exposure mode based on the user context. The user context may include, e.g., at least one of panning, walking, standing, sitting, and traveling in a moving vehicle.

Abstract: Described herein are methods, apparatus, and computer readable medium to autofocus a lens of an imaging device. Parameters are received indicating a lens position. Lens actuator characteristics are determined. Lens damping parameters may be determined based, at least in part, on the input parameters and the lens actuator characteristics. In some aspects, lens damping parameters include a lens movement step size and a time delay between each step. In some aspects, the lens damping parameters include damping parameters for a plurality of regions of lens movement. Lens movement parameters are determined based, at least in part, on the input parameters and the lens damping parameters. The lens is then autofocused by moving it according to the lens movement parameters.
