ABSTRACT:
A method of attenuating noise contained in an image signal according to the extent of the movement of the image signal based on the amount of noise, and an apparatus therefor are provided. This method includes measuring the amount of noise in an image signal by accumulating an offset between an input image signal and a delayed output image signal for a predetermined time, detecting the extent of the movement of the input signal based on the amount of noise measured, and forming an output image by controlling the specific weight of the input image signal and the delayed output image signal according to the detected movement.
