ABSTRACT:
A method and system for converting color image data (data outputting from element202) from a, for example, three-dimensional color space format to a format usable by an n-primary display (206), wherein n is greater than or equal to 3. The system (converter204) may define a two-dimensional sub-space having a plurality of two-dimensional positions, each position representing a set of n primary color values and a third, scaleable coordinate value for generating an n-primary display input signal (signal inputting toi display206). Furthermore, the system may receive a three-dimensional color space input signal including out-of range pixel data not reproducible by a three-primary additive display, and may convert the data to side gamut color image pixel data suitable for driving the wide gamut color display.
