1. A digital image acquisition device, comprising: an image capture component for capturing digital images; a digital processing component, including: a processor; and embedded code for programming the processor to initiate notifying a photographer, de-blurring a digital image, or delaying or initiating a subsequent image capture, or combinations thereof, 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 said digital image acquisition device, such that said same digital image acquisition device captures 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 the threshold camera motion blur comprises a qualitative non-zero distortion amount around one or more points or lines or both in the image compared to one or more relatively sharp matched points or lines, or both, in the at least one further 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 the digital processing component is further arranged to determine whether to notify the photographer, de-blur said captured digital image or delay or initiate a subsequent image capture depending on whether the threshold camera motion blur has occurred in the captured digital image.
