Abstract
An image processing apparatus is provided for reducing noise from an original image consisting of digital image data. The apparatus has an information calculator, smoothed image producer, weighting-factor calculator, and weighting adder. The information calculator calculates information in relation to a pixel-value change representing a degree that becomes larger with a spatial change in a pixel value averaged each predetermined area on the original image. The smoothed image producer produces a smoothed image by smoothing the original image. The weighting-factor calculator calculates a weighting factor depending on the calculated information in relation to the pixel-value change. The weighting adder mutually performing, using the weighting factor, weighting addition with either the original image or an image modulated from the original image and the produced smoothed image.
