Claim One:
1. A method of using a processor to correct a flash image orb artifact arising from specular reflections from airborne particles, comprising: (a) acquiring an image of a scene using flash illumination; (b) acquiring a reference image of substantially the same scene; (c) subtracting the reference and flash images to generate a difference image; (d) determining an edge feature of an orb artifact within the difference image; (e) determining a feature of an interior region of an orb artifact within the difference image; (f) matching the edge feature with the feature of the interior region; (g) correcting the orb artifact from the flash image based on the matching, thereby generating a corrected image; and (h) displaying, transmitting, communicating or digitally storing or otherwise outputting the corrected image or a further processed version, or combinations thereof.
