Abstract
A light source mixture control device for controlling a light source emitting different spectrums is provided. A coordination conversion unit receives and converts a hue signal and a luminance signal into a first to a third undecoupled color light component. A first color light component decoupling control unit decouples a first color light component from the first to the third undecoupled color light component. A second color light component decoupling control unit decouples the first undecoupled color light component into a first decoupled color light component. A third color light component decoupling control unit decouples the second undecoupled color light component into a second decoupled color light component. A fourth color light component decoupling control unit decouples the third undecoupled color light component into a third decoupled color light component. The first to the third decoupled color light component respectively control the light source.
