ABSTRACT:
A signal processing unit in a liquid crystal display device, etc., includes a brightness component appearance frequency measuring unit that measures an appearance frequency of each brightness component in a video signal; a parameter outputting unit that outputs a distribution of each brightness component, as a parameter, based on the appearance frequency of each brightness component measured by the brightness component appearance frequency measuring unit; a changing signal outputting unit that alters an input signal recorded in a recording unit, by using the parameter, and that outputs the input signal as a changing signal; and a brightness component changing unit that changes a distribution of each brightness component, by using the changing signal, and that outputs the video signal in which the distribution of each brightness component is changed.
