The accentuation method (20) determines the relative magnitude (Fig. 3 S 1-4) , of each color component. It selects (24) and adjusts (26) the magnitude of one or more of the colors as a function of the determined relative magnitudes (Fig.3, S 1-4) of each color component. The type and amount of the adjustment (26) is a function of the relative magnitude (Fig. 3 S 1-4) differences. One , or more of the magnitudes (Fig. 3 S 1-4) is adjusted (26) to change the relative magnitudes (Fig. 3, S 1-4). Typically the differences in the , subtractive color space is between the lowest and middle magnitude color. Also, typically, the lowest primary color component is reduced.

Why it's free to use
- Filed August 17, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended August 17, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 17, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
