Patent ID: 7636486

Claim:
A digital image acquisition system comprising an apparatus for capturing digital images and a digital processing component for determining a camera motion blur function in a captured digital image based on a comparison of at least two sets of image data, including at least one relatively low resolution reference image, each acquired with a same sensor, such that at least a same portion of said same sensor captures at least a portion of each of said at least two sets of image data, within a temporal range that includes an exposure period of the captured digital image, and times proximately before and after said exposure period, and of nominally the same scene as that of the captured digital image, and wherein said at least two sets of image data comprise said at least one relatively low resolution reference image, or at least one processed version of said at least one reference image taken outside the exposure period of said captured digital image and modified pursuant to processing including aligning or matching pixel resolution of said at least two sets of image data, or both, and wherein said digital processing component is arranged to compare the at least two sets of image data for determining said camera motion blur function in said captured digital image, and to determine to de-blur said captured digital image only when the camera motion blur function indicates that sufficient blur exists within the captured digital image.
