ABSTRACT:
A color display device includes a shutter type color display and signal processing means. The signal processing means has color conversion processing means for increasing a gradation level of a color signal having the highest gradation level while decreasing a gradation level of a color signal having the lowest gradation level when the gradation levels of the plural color signals are not equal one another, and for outputting a color signal has been processed to the shutter type color display. Further, a color display having a reflective member or a diffuse transmission member provided on a display screen or in the vicinity of the display screen, a color plasma display, or a color field emission display can also be used instead of the shutter type color display. Thus, even when chroma of the color display is low, a display in high chroma can be ensured.
