DISPLAY DEVICE, METHOD FOR GENERATING FOUR OR MORE PRIMARY COLOR SIGNALS, AND PROGRAM CAUSING COMPUTER TO EXECUTE PROCESSING FOR GENERATING FOUR OR MORE PRIMARY COLOR SIGNALS

摘要

A display device is designed to conduct a display operation using a number n of primary colors (where n is a natural number that is equal to or greater than four). The display device includes a video signal converting section that receives an m-primary-color signal representing a number m of primary colors (where is m is also a natural number that is smaller than n) and that converts the m-primary-color signal into an n-primary-color signal representing the n primary colors. The n primary colors include a color that is complementary to a particular one of the m primary colors. The video signal converting section generates the n-primary-color signal such that if a color component representing the particular primary color of the m-primary-color signal has a negative level, the complementary primary color has an increased luminance and the other non-complementary primary colors have decreased luminances compared to a situation where the color component representing the particular primary color is zero.
