Abstract
Systems and methods for a multi-primary color system for display. A multi-primary color system increases the number of primary colors available in a color system and color system equipment. Increasing the number of primary colors reduces metameric errors from viewer to viewer. One embodiment of the multi-primary color system includes Red, Green, Blue, Cyan, Yellow, and Magenta primaries. The systems of the present invention maintain compatibility with existing color systems and equipment and provide systems for backwards compatibility with older color systems.

A system for displaying a primary color system, comprising:
- a set of image data including a set of primary color signals, wherein the set of primary color signals corresponds to a set of values in a color space, wherein the set of values in the color space includes at least two colorimetric coordinates;
- an image data converter operable to encode and decode the set of values in the color space, wherein the image data converter includes a digital interface;
- at least one non-linear function for processing the set of values in the color space, wherein the at least one non-linear function is applied to data related to a luminance and data related to the at least two colorimetric coordinates;
- and
- at least one viewing device;
- wherein the at least one viewing device and the image data converter are in communication;
- wherein processed data is transported between the encode and the decode;
- wherein the image data converter is operable to convert the set of image data for display on the at least one viewing device;
- and
- wherein the image data converter includes a three-dimensional (3D) look-up table (LUT) and/or a two-dimensional (2D) look-up table (LUT).
A system for displaying a primary color system, comprising:
- a set of image data including a set of primary color signals, wherein the set of primary color signals corresponds to a set of values in a color space;
- an image data converter operable to encode and decode the set of values in the color space, wherein the image data converter includes a digital interface;
- at least one non-linear function for processing the set of values in the color space, wherein the at least one non-linear function is applied to data related to at least two colorimetric coordinates;
- and
- at least one viewing device;
- wherein the at least one viewing device and the image data converter are in communication;
- wherein the encode and the decode include transportation of processed data;
- wherein the image data converter is operable to convert the set of image data for display on the at least one viewing device;
- and
- wherein the image data converter includes a three-dimensional (3D) look-up table (LUT) and/or a two-dimensional (2D) look-up table (LUT).
A method for displaying a primary color system, comprising:
- providing a set of image data including a set of primary color signals, wherein the set of primary color signals corresponds to a set of values in a color space;
- encoding the set of image data in the color space using a digital interface of an image data converter, wherein the image data converter is in communication with at least one viewing device;
- processing the set of image data in the color space by scaling at least two colorimetric coordinates and applying at least one non-linear function to the scaled at least two colorimetric coordinates;
- decoding the set of image data in the color space using the image data converter;
- and
- the image data converter converting the set of image data for display on the at least one viewing device;
- wherein the image data converter includes a three-dimensional (3D) look-up table (LUT) and/or a two-dimensional (2D) look-up table (LUT);
- and
- wherein the encoding and the decoding include transportation of processed data.
