Color signal converter, display unit, color signal conversion program, computer-readable storage medium storing color signal conversion program, and color signal conversion method

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.

1. A color display apparatus for displaying a color image, comprising:
a color conversion circuit configured to convert a three-color video signal into a n-color video signal (n≧4), the three-color video signal representing at least a first color component, a second color component and a third color component, and the n-color video signal representing at least the first color component, the second color component and the third color component; and a display panel including n-color pixels corresponding to n colors of the n-color video signal, the color image being made up of the n colors; wherein
the three-color video signal includes three pixel color values,the first color component and the second color component of the three-color video signal are represented by at least one of the three pixel color values, and the third color component of the three-color video signal is represented by at least two of the three pixel color values,the n-color video signal includes n pixel color values,the first color component, the second color component and the third color component of the n-color video signal are represented by at least one of the n pixel color values, andin a case where the third color component is reproduced by the display panel, an output luminance of the third color component represented by the n-color video signal is higher than an input luminance of the third color component represented by the three-color video signal.
