Abstract

A video-signal-processing device has luminance conversion section that performs level compression on three input primary-color signals of a color video signal at a same luminance adjustment compression ratio with a hue and a saturation of the color video signal being kept constant, thereby generating three compressed primary-color signals. The device also has saturation conversion section that performs level conversion on the three compressed primary-color signals by using a saturation compression ratio if a maximum level of at least one of the three compressed primary-color signals exceeds a first level. The saturation conversion section sets the saturation compression ratio by using a minimum level one of the three compressed primary-color signals.
