Abstract: An image signal processor (ISP) processes received image frame data. In order to reduce power consumption caused by the processing of substantially similar image tiles of received image frames, differential processing may be used to determine which image tiles of a received image frame should be processed by the ISP, based upon a comparison between the received image tiles and previously received image tile data. In addition, differential processing may be automatically disabled in response to a determination that the image frames are too different from each other to realize any savings in processing resources or memory usage, and reenabled in response to a determination the received image frames are similar enough such that power savings can be realized through differential processing.

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.
