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.
Claims20
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 an International Commission on Illumination (CIE) Yxy color space, wherein the set of values in the CIE Yxy color space includes a luminance (Y) and two colorimetric coordinates (x and y);
- an image data converter, wherein the image data converter includes a digital interface, and wherein the digital interface is operable to encode and decode the set of values in the CIE Yxy color space;
- and
- at least one viewing device;
- wherein the at least one viewing device and the image data converter are in communication;
- wherein processed Yxy 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 system for displaying the primary color system modifies a performance of the at least one viewing device, wherein the at least one viewing device is operable to utilize a maximum color range of the at least one viewing device.

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 an International Commission on Illumination (CIE) Yxy color space, wherein the set of values in the CIE Yxy color space includes a luminance (Y) and two colorimetric coordinates (x and y);
- encoding the set of image data in the CIE Yxy 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;

- decoding the set of image data in the CIE Yxy color space using the digital interface of 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 encoding and the decoding include transportation of processed Yxy data;
- and
- wherein a performance of the at least one viewing device is modified, wherein the at least one viewing device is operable to utilize a maximum color range of the at least one viewing device.
