ABSTRACT:
In a method and apparatus for converting digitized luminance-chrominance color space signals to digitized RGB color space signals, starting chrominance-in-color terms of a standard set of conversion equations are expanded into linear combinations of expanded chrominance-in-color terms that involve only predictive and compensative coefficients. Predictive and compensative code generators respectively generate predictive and compensative transformation codes that correspond to a first one of the chrominance color space signals during a first timing phase and that correspond to a second one of the chrominance color space signals during a second timing phase. The predictive and compensative transformation codes from the predictive and compensative code generators are transformation values for the expanded chrominance-in-color terms and are linearly combined to obtain transformation values for the starting chrominance-in-color terms. Finally, the transformation values for the starting chrominance-in-color terms are combined with the luminance color space signal according to the standard set of conversion equations to obtain the RGB color space signals.
