Device, system and method of data conversion for wide gamut displays
First Claim
1. A method of converting color image data to a format usable by a wide gamut color display capable of reproducing images out of a gamut described by color display standards, the method comprising:
- receiving an input signal, in a three-dimensional color space, representing three-dimensional color image pixel data including out-of-range pixel data, said out-of-range pixel data being outside a color gamut reproducible by a three-primary additive display compliant with a color display standard;
converting said three-dimensional color space input data into wide color gamut image pixel data comprising display data for each of the primary colors of the wide color gamut display, at least a portion of which corresponds to at least some of said out-of-range pixel data; and
based on said wide color gamut image pixel data, generating a wide color gamut input signal suitable for driving said wide gamut color display.

Abstract
A method and system for converting color image data (data outputting from element 202) 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 (converter 204) 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 display 206). 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.
