A weighted gain generator sets a high frequency information detecting frame in an imaging screen of an image sensor, after that, sets a reference point in the high frequency information detecting frame, and sets such a weighting that has correspondence to a distance between a position of a targeted pixel in the imaging video signal and the reference point to a gain of the targeted pixel. A gain adjuster makes the gain weighted by the weighted gain generator act on the high frequency component of the imaging video signal.
