摘要：
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.
