Abstract
An image processing apparatus, an image processing method, and a computer program, visually remove low-frequency noise contained in image data. Image data containing low-frequency noise is input from an input terminal. A window unit designates a window made up of a pixel of interest, and its surrounding pixels. A pixel selector selects a selected pixel to be compared with the pixel of interest from the window, and a pixel value determination unit determines a new pixel value of the pixel of interest on the basis of the pixel values of the selected pixel and pixel of interest. New image data is generated by substituting the pixel value of the pixel of interest by the new pixel value.
