An aspect of this disclosure is an apparatus for capturing an image. The apparatus comprises an image sensor configured to capture an image of a field of view. The apparatus also comprises a flash component configured to illuminate at least a portion of the field of view at a power level during capture of a first frame by the image sensor. The apparatus further comprises a controller. The controller is configured to determine a flash ramp-up time for the flash component, the flash ramp-up time corresponding to an amount of time between a flash being requested at the power level and the flash component producing the flash at the power level. The controller is also configured to blank the image sensor for a blanking period during the flash ramp-up time.

Methods and apparatus for synchronizing camera flash and sensor blanking

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.
