1. 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 and a captured digital image, each acquired with a same sensor, such that at least each pixel of a same portion of said same sensor captures at least a pixel of each of said at least two sets of image data, wherein said apparatus is configured to capture each said at least one relatively low resolution reference image within a temporal range that includes times proximately before or after said exposure period, and such that the captured digital image and each said at least one relatively low resolution reference image comprise approximately the same scene, and wherein said digital processing component is arranged to: align at least portions of the at least two sets of image data; and compare the at least two sets of image data for determining said camera motion blur function in said captured digital image including calculating a point spread function (PSF) to points within an object captured within the captured digital image, and determine to de-blur said captured digital image when the camera motion blur function indicates that sufficient blur exists within the captured digital image, and deblur the captured digital image by de-convolving the captured digital image using the point spread function (PSF).
