Abstract
A digital image processing method for eliminating Moiré in a digital image divided into pixels holding pixel component values includes selecting a first pixel and defining a pixel window around the selected first pixel. Then, a set of pixels are identified which consist of pixels within the window that have pixel component values within a pixel component value range that is related to the selected first pixel. A pixel component value is calculated based on corresponding pixel component values of pixels in the set of pixels and then this calculated pixel component value is allocated to the selected first pixel.
