A method of automatically correcting dust artifact regions within images
acquired by a digital image acquisition system including a digital camera
with a lens assembly includes determining probabilities that certain
pixels within multiple digitally-acquired images correspond to one or
more dust artifact regions. A statistical dust map is formed including
mapped dust artifact regions based on the dust artifact determining. The
mapped dust artifact regions are separated into aura regions partially
obscured by dust and shadow regions substantially obscured by dust inside
the aura regions. Digital data are corrected corresponding to pixels
within one or more digitally-acquired images including dust artifact
regions separated into aura regions and shadow regions correlated with
mapped aura and shadow regions of the statistical dust map.
