Abstract
A circuit for eliminating a ghost noise of an image processing system in transmitting an image signal, wherein an image data and a noise are separated from each other visually and the ghost noise added during transmitting is changed to a white noise so as to reduce an extent of deterioration of a picture quality because a pattern of a data scrambled at each frame is changed by an initial value being different at each frame.
