摘要
Disclosed is a pattern noise removal device for removing background pattern noise having periodicity from a digital image, which includes a candidate pixel extracting module for extracting candidate pixels that constitute the background pattern noise from the pixels in the image on the bases of the concentration of each of the pixels, a dot pattern feature extracting module for extracting the feature of a dot pattern formed by each of the candidate pixels and the peripheral neighborhood pixels among the extracted candidate pixels, a dot pattern area extracting module for extracting a dot pattern area including the candidate pixels of the periodicity and the neighborhood pixels, which have the feature of the dot pattern, and a periodic pattern noise removal module for removing the candidate pixels of the periodicity and the neighborhood pixels, which are included in the dot pattern area, as the background pattern noise.
