Abstract
A Gaussian filterhaving a first cutoff frequency extracts a low frequency component signal of a video signal. A subtracterextracts a high frequency component signal by subtracting the low frequency component signal from the video signal. A low pass filterhaving a second cutoff frequency higher than the first cutoff frequency extracts a lower high frequency component signal, which is a low-frequency-side signal of the high frequency component signal. A multipliergenerates a corrected component signal by multiplying the lower high frequency component signal by a predetermined gain G. An adderadds the corrected component signal to the video signal.
