Abstract:
An image processing device includes an isolated point noise detection section, and an isolated point noise correction section. The isolated point noise detection section determines whether or not isolated point noise is included within a given area based on a first index value that represents the range of first to nth pixel values being obtained by arranging the pixel values of pixels within the given area including an attention pixel in ascending or descending order, and a second index value that represents the range of a pixel value group being obtained by excluding at least one of the first pixel value and the nth pixel value from the first to nth pixel values. The isolated point noise detection section determines whether or not the attention pixel is a pixel that corresponds to isolated point noise when it has been determined that isolated point noise is included within the given area.
