A color signal adjustment module adjusts first through third color signals corresponding to first through third colors expressing a color image. The color signal adjustment device includes: first through fourth RAMs available as lookup tables for adjusting color signal levels; an address selection module that replaceably allocates the first through the third color signals and a predetermined address signal to input address signals of the first through the fourth RAMs, in response to a preset selection signal; and a data selection module that selectively outputs at least three output signals among output signals from the first through the fourth RAMs as first through third output color signals corresponding to the first through the third colors, in response to the preset selection signal. Such arrangement enables lookup tables to be rewritten without causing superimposition of noise in a displayed image or a variation in color tone of the displayed image. |
