A method of automatically correcting dust artifact within images acquired
by a system including a digital camera includes determining probabilities
of dust artifact regions corresponding to pixels within a
digitally-acquired image based at least in part on a pixel analysis of
the region in view of predetermined characteristics indicative of the
presence of a dust artifact region. The dust artifact regions are
associated with one or more extracted parameters relating to the optical
system when the image was acquired. A statistical dust map is formed
including mapped dust regions based on the dust artifact determining and
associating operations. Digital data is corrected corresponding to
correlated dust artifact regions within the acquired image based on the
associated statistical dust map.
