ABSTRACT:
The present invention discloses a method and an apparatus for correcting color mixing errors, which lets a color display device adopt a virtual material quantity concept and use at least one set of predetermined virtual primary colors to analyze mixed color signal values displayed on the color display device and establish a corresponding material characteristic functions between color control signal values and corresponding virtual control signal values, and eventually establish nonlinear color correction functions between a series of known control signal values corresponding to desired color signal values of the color display device, in such a way that when the color display device performs a video color conversion, the control signal values actually entered into the color display device are corrected to the corresponding target control signal values for allowing the color display device to display desired color signal values.
