Abstract
Flash image orb artifacts arising from specular reflections from airborne particles are corrected. A specific location is detected within a digital image of a flash image airborne particle artifact (orb). A defined curved plane shape is electronically identified within the image. Luminances are analyzed of pixels within the identified shape to assess whether the shape in fact corresponds to an orb. The digital image is corrected by removing the orb. One or more pixel values are adjusted inside the orb, and one or more edge pixel values of the orb are also adjusted.
