Abstract: A method and apparatus for removing noise in a dark area of an image are provided. An edge magnitude in an N×N window image including a plurality of pixels is calculated. It is determined whether an edge area is present in the window image on the basis of the edge magnitude. A mean value of brightness of the window image is calculated when the edge area is not present. It is determined whether the window image corresponds to a bright area or a dark area on the basis of the mean value. The window image is determined as the bright area when the mean value is higher than a preset brightness reference value, and low-pass filtering is performed on the window image. The window image is determined as the dark area when the mean value does not exceed the reference value, and minimum filtering is performed on the window image.
