1. A digital image processing method of eliminating Moiré
- in a pixilated digital image wherein each pixel is associated with at least a first pixel component value and a second pixel component value of different type, the method comprising;
selecting a pixel;
defining a pixel window around the selected pixel;
identifying a set of pixels consisting of pixels within the pixel window having a first pixel component value within a range that is related to the first pixel component value of the selected pixel;
calculating a new second pixel component value for the selected pixel using corresponding second pixel component values of pixels in the set of pixels; and
allocating the calculated new second pixel component value to the selected pixel.

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.
