摘要： This disclosure provides systems, methods, and apparatus for generating images on a display. A multi-primary display can include control logic that converts input image data into the multi-primary color space employed by the display by mapping the input pixel values into the XYZ color space according to a gamut mapping function and then decomposing the XYZ tristimulus values into color subfields associated with the display's primary colors. For example, such a process can be used to covert image frames encoded in an RGB color space into a RGBW color space. In some implementations, the control logic can adapt the gamut mapping and/or the decomposition processes based on a saturation level of the image being processed.
