Abstract

The color accentuation method determines the relative magnitude of each color component in each (34a, 34b). It selects and adjusts the magnitude of one or more of the colors as a function of the determined relative magnitudes of each color component. The type and amount of the adjustment is a function of the relative magnitude differences (40a, 40b). One or more of the magnitudes is adjusted to change the relative magnitudes. Typically, the difference in a subtractive color space is between the lowest and middle magnitude color (36b) and in an additive color space is between the highest and the middle magnitude color (36a). Also, typically, the lowest color component is reduced in the subtractive color space and the highest is increased in the additive color space. Various scaling functions (38a, 38b) and compensations or adjustments (42a, 42b) of the color accentuation may be used.
