Abstract:
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.
