Abstract

PURPOSE: To delete the noise completely from the video signal regardless of the types of the monochrome video signal, color video signal and the Tv system through the simple circuit of the digital structure.
CONSTITUTION: The 1st noise deleting circuit NR1 which deletes the noise through process of the video signal sent from input terminal P1 based on the 1- or 2-dimensional interrelation is provided, along with 2nd noise deleting circuit NR2 which supplies output signal P22 sent from circuit NR1 and deletes the noise through process of the video signals based on the frame interrelation. Thus, output signal P21 from circuit NR1 is applied to compound circuit PC via delay circuit DC to be added to the output of circuit NR2. And the output picture signal with the noise deleted is delivered through output terminal P3.
