Abstract
A video signal processor comprises a first filtering circuit, a first and a second emphasis circuits, a noise removing circuit, and a converter. The first filtering circuit filters an input video signal, and extracts a low frequency component. The first emphasis circuit emphasizes the low frequency component, and outputs a first emphasized signal. The second emphasis circuit emphasizes the first emphasized signal, and outputs a second emphasized signal. The noise removing circuit removes a noise component from either the first emphasized signal or the second emphasized signal, and outputs the noise-removed signal. The converter converts the noise-removed signal into a frequency-modulated signal.
