Color signal converter, display unit, color signal conversion program, computer-readable storage medium storing color signal conversion program, and color signal conversion method
First Claim
1. A color signal converter that converts a three-primary-color signal to an n-color signal (n≧
- 4), the color signal converter comprising;
a first color signal generation module for generating, by subjecting the three-primary-color signal to isochromatic conversion, an m-color signal made up of m color components (m≧
n) including respective color components that are equivalent in terms of color to color components of the n-color signal; and
a second color signal generation module for generating the color components of the n-color signal, by performing linear combination of the color components of the m-color signal.

Abstract
A color conversion circuit converts a three-primary-color signal PS0 to a 5-color signal PS5, and includes (i) a color component extraction module that generates, by performing isochromatic conversion, a 7-color signal PS2 made up of 7 color components equivalent in terms of color to color components d1 through d5 of the 5-color signal PS5, and (ii) a matrix operation module that generates color components of the 5-color signal by performing linear combination of the color components of the 7-color signal. With this, it is possible to realize a color conversion circuit by which colors represented by a signal after conversion can be adjusted using intuitively-understandable parameters.
