Abstract
A technique of achieving optimal noise suppression with respect to a video signal whose noise amount differs according to brightness is disclosed, and according to the technique, a low-luminance detecting sectiondetects a video signal of a relatively low luminance, a suppression amount setting sectiongenerates a noise suppression amount which becomes larger as the luminance of the video signal becomes lower, and a noise suppressing circuitsuppresses noise with the noise suppression amount generated by the suppression amount setting section with respect to the video signal of a relatively low luminance detected by the low-luminance detecting section.
