Patent ID: 7697778

Claim:
A digital image acquisition system, comprising an apparatus for capturing digital images and a digital processing component for notifying a photographer upon determining that a threshold camera motion blur has occurred in a captured digital image based on a real time analysis of the captured digital image and at least one further 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 captured digital image and said at least one further image, 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 captured digital image and said at least one further image are compared, the at least one further image comprising a lower pixel resolution than the captured digital image; and wherein said digital processing component is arranged to match the pixel resolutions of the captured digital image and the at least one further image by at least one of up-sampling the at least one further image and sub-sampling the captured digital image; and wherein the digital processing component is further arranged to determine whether to de-blur said captured digital image depending on whether the threshold camera motion blur has occurred in the captured digital image.
