Claim One:
1. A high-speed image acquisition system comprising: a sensor movable relative to a target; an illuminator adapted to direct illumination upon the target at a plurality of illumination levels; wherein the sensor obtains a first set of at least one image at a first illumination level during relative motion between the sensor and the target, and the sensor obtains a second set of at least one image at a second illumination level of the plurality of illumination levels during relative motion between the sensor and the target; wherein the first and second illumination levels differ from each other by a known ratio, and wherein an unusable portion from one set of at least one image is replaced based upon the other set of at least one image and the known ratio; and an image processor coupled to the sensor and adapted to create an extended dynamic range image based at least in part upon cositing the first set of at least one image with the second set of at least one image.
