Abstract

PURPOSE: The noise is detected which surpasses the peak-to-peak value of the synchronous signal mixed in video signals, and the video signal in the noise period is fixed to a gray level to display the noise elongated to a black-level side in gray, thereby making the noise part inconspicuous.
