Video signal processor processing color signals whose bands are limited

A video signal processor to which a luminance signal and a color signal are supplied, comprising:

• a first low-frequency component calculating circuit for calculating a low-frequency component of the luminance signal;
• a second low-frequency component calculating circuit for calculating a low-frequency component of a color-difference signal derived from both of the luminance signal and the color signal;
• a high-frequency component extracting circuit for extracting a high-frequency component of the luminance signal;
• a division circuit for dividing the low-frequency component of the color-difference signal by the low-frequency component of the luminance signal;
• a multiplication circuit for multiplying an output signal from the division circuit by the high-frequency component of the signal extracted from the high-frequency component extracting circuit, a multiplied signal being outputted as a correction signal for the color signal;
• and
• an addition circuit for adding the correction signal to the color signal.
