Abstract: A ringing noise removing apparatus and a noise removing apparatus are provided to improve the quality of a digital image by removing blocking discontinuity noise and ringing noise. A ringing noise removing apparatus(200) includes a representative value set unit, a parameter generator, and a compensator. The representative value set unit performs a corrected K-means algorithm for pixel data included in a block with a plurality of pixel data to divide it into two groups, and determines each representative value in each of the groups. The parameter generator obtains interval and approach between all the pixel data in the block and the two representative values. The compensator compensates input pixel data using the interval and the approach. The interval is a distance between the input pixel data and a representative value in a group to which the input pixel data belongs. The approach is a ratio between the distance between the input pixel data and a representative value in a group to which the input pixel data belongs, and a distance between the input pixel data and a representative value in a group to which the input pixel data does not belong.
