METHOD AND APPARATUS FOR VIDEO IMAGE NOISE REMOVAL

摘要

PROBLEM TO BE SOLVED: To provide a method and apparatus for effectively removing noise in a frequency domain by converting video or still image data distorted by noise in the frequency domain.

SOLUTION: The noise removal method includes: classifying a received original signal into predetermined size blocks (a); generating at least one signal rebuilding a block by removing the classified signals as many as the predetermined number of pixels within the range for the number of pixels in the above block; and removing noise in the frequency domain by converting the original signal and the rebuilt signal into signals in the frequency domain. As a result, noise in still image and video signals is effectively removed.
