ABSTRACT:
A noise reduction system for reducing noise in a video signal comprises a pre-emphasis circuit for subjecting the video signal which is supplied to a transmission system to a pre-emphasis in a vertical direction of a picture and in a direction oblique to the vertical direction, and a de-emphasis circuit for subjecting the pre-emphasized video signal obtained through the transmission system to a de-emphasis complementary to the pre-emphasis.
