The conversion preferably involves a method of converting the luminance level to color information of three primary colors, red, green, blue, in accordance with a plurality of weights, respectively, a method of converting a luminance level in a predetermined range to color information having a changing rate larger than a changing rate of the luminance level, a method of converting a luminance level out of the predetermined range to color information of a maximum or a minimum level, or the like. Also, the input video signal is preferably displayed together with a converted video image side by side or one on another.
