Abstract (en)

[origin: WO2004017261A2] The color accentuation method determines the relative magnitude of each color component in each pixel or area. T 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 may be a function of the relative magnitude differences. One or more of the magnitudes is adjusted to change the relative magnitudes. Typically, the difference in a subtractive color space s between the lowest and middle magnitude color and n an additive color space is between the highest and the middle magnitude color. Also, typically, the lowest color component s reduced in the subtractive color space and the highest is increased in the additive color space. Various scaling functions and compensations or adjustments of the color accentuation may be used.
