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
First Claim
1. A display device for conducting 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 comprising:
- a video signal converting section arranged to receive an m-primary-color signal representing a number m of primary colors, where m is a natural number that is smaller than n, and arranged to convert the m-primary-color signal into an n-primary-color signal representing the n primary colors; and
a pixel including multiple subpixels;
whereineach of the multiple subpixels represents an associated one of the n primary colors;
the n primary colors include a color that is complementary to a particular one of the m primary colors; and
the video signal converting section is arranged to generate 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 and at least four of the subpixels included in the pixel are lit.

Abstract
A display device using a number n of primary colors (where n is a natural number that is equal to or greater than four) 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.

12. A method for generating an n-primary-color signal that represents a number n of primary colors, where n is a natural number that is equal to or greater than four, in order to conduct a display operation using the n primary colors, wherein a pixel includes multiple subpixels, each of the multiple subpixels represents an associated one of the n primary colors, the method comprising:
-
a step of converting an m-primary-color signal received, representing a number m of primary colors, where is m is a natural number that is smaller than n, into the n-primary-color signal;
whereinthe n primary colors include a color that is complementary to a particular one of the m primary colors; and the step of converting includes generating 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 and at least four of the subpixels included in the pixel are lit.

13. A non-transitory computer readable medium storing a computer program with a program code for performing, when the computer program runs on a computer, a method of generating an n-primary-color signal that represents a number n of primary colors, where n is a natural number that is equal to or greater than four, in order to conduct a display operation using the n primary colors, wherein a pixel includes multiple subpixels, each of the multiple subpixels represents an associated one of the n primary colors and the method of generating comprising a step of converting an m-primary-color signal received, representing a number m of primary colors, where is m is also a natural number that is smaller than n, into the n-primary-color signal, wherein the n primary colors include a color that is complementary to a particular one of the m primary colors, and the step of converting includes generating 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 and at least four of the subpixels included in the pixel are lit.
