Abstract
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.

A method of color accentuation in a color processing system comprising:
- determining the relative magnitude of each color component of a color separation;
- determining, for a subtractive color space, the difference of the magnitude of a middle color component to a lowest color component and, for an additive color space, the difference of the magnitude of a highest color component to a middle color component;
- and
- selecting and adjusting the magnitude of one or more of the color components as a function of the determined difference of the middle color component to the lowest color component for the subtractive color space and as a function of the determined difference of the highest color component to the middle color component for the additive color space.
A color processing system for receiving input signal for an image to be displayed in color, the system including a signal processor and wherein the signal processor:
- receives or derives color separation from the input signals;
- determines for a subtractive or an additive color space the relative magnitude of each color of the color separation;
- determines, for the subtractive color space, the difference of the magnitude of a middle color component to a lowest color component and, for the additive color space, the difference of the magnitude of a highest color component to a middle color component;
- and
- selects and adjusts the magnitude of one or more of the color components as a function of the determined difference of the middle color component to the lowest color component for the subtractive color space and as a function of the determined difference of the highest color component to the middle color component for the additive color space.
A method of color accentuation of a color image made up of areas, encoded in a color space, the method comprising:
- detecting in each area the magnitude of each color component of the color space;
- and
- changing the magnitude of color components in each area in accordance with a pre-determined scaling function applied to the detected color components to increase the difference between a maximum and a minimum color component in each area, the scaling function being based on a difference of a middle color component to the lowest color component for a subtractive color space or on a difference of the highest color component to the middle color component for an additive color space for each area.
