Abstract
An apparatus for removing a ghost component which disturbs a picture signal by means of a ghost canceling reference signal included therein. The reference signal is extracted from the picture signal and judged as to whether it has a specific level in a reference time interval. The extracted reference siganl is also judged as to whether a color burst signal is canceled. If both judgements are positive, a judgement signal is generated which allows the extracted signal to be examined how it is disturbed by the ghost component. In response to the examination, the ghost component is removed from the picture signal.
