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.

Claims (42)

1. A system for displaying a primary color system, comprising:

a set of image data;

an image data converter; and

at least one display device;

wherein the set of image data includes primary color data for at least four primary color values;

wherein the at least four primary color values include a first white emitter and a second white emitter, wherein the first white emitter and the second white emitter have different color temperature values;

wherein the at least one display device and the image data converter are in network communication; and

wherein the image data converter is operable to convert the set of image data for display on the at least one display device.

2. The system of claim 1 , wherein the first white emitter and the second white emitter are selected from a group consisting of a D65 white emitter, a D60 white emitter, a D45 white emitter, a D27 white emitter, and a D25 white emitter.

3. The system of claim 1 , wherein the at least four primary color values include a red primary, a green primary, a cyan primary, and a blue primary.

4. The system of claim 1 , wherein the at least four primary color values include a red primary, a first green primary, a second green primary, and a blue primary, wherein the first green primary and the second green primary have different chromaticity values.

5. The system of claim 1 , wherein the at least four primary color values include a red primary, a yellow primary, a green primary, a cyan primary, and a blue primary.

6. The system of claim 1 , wherein the at least four primary color values include a red primary, a green primary, a blue primary, a cyan primary, a magenta primary, and a yellow primary.

7. The system of claim 1 , wherein the set of image data defines a minimum color luminance and a maximum color luminance.

8. The system of claim 1 , wherein the at least four primary color values are operable to be expressed using a tristimulus color vector, a linear display control vector, and a conversion matrix.

9. The system of claim 1 , wherein the image data converter includes a digital interface, wherein the digital interface encodes and decodes the set of image data using at least one color difference component, and wherein the at least one color difference component is operable for up-sampling and/or down-sampling.

10. The system of claim 1 , wherein the at least four primary color values include a third white emitter, wherein the third white emitter has a different color temperature than the first white emitter and the second white emitter.

11. The system of claim 1 , wherein the at least four primary color values include a magenta primary, and wherein the magenta primary is derived from the set of image data.

12. The system of claim 1 , wherein the at least four primary color values include a first red primary, a second red primary, a first green primary, a second green primary, a first blue primary, and a second blue primary.

13. The system of claim 12 , wherein the first red primary, the first green primary, and the first blue primary are narrow band primaries, and wherein the second red primary, the second green primary, and the second blue primary are wide band primaries.

14. A system for displaying a primary color system, comprising:

a set of image data;

an image data converter, wherein the image data converter includes a digital interface, wherein the digital interface is operable to encode and decode the set of image data; and

at least one display device;

wherein the set of image data includes primary color data for at least four primary color values, wherein the at least four primary color values include a cyan primary;

wherein the at least four primary color values further include a first white emitter and a second white emitter, wherein the first white emitter and the second white emitter have different color temperature values;

wherein the at least one display device and the image data converter are in network communication; and

wherein the image data converter is operable to convert the set of image data for display on the at least one display device.

15. The system of claim 14 , wherein the cyan primary is positioned to limit maximum saturation.

16. The system of claim 14 , wherein the cyan primary is positioned by expanding a set of hue angles.

17. A system for displaying a primary color system, comprising:

a set of image data;

an image data converter;

a set of Session Description Protocol (SDP) parameters; and

at least one display device;

wherein the set of image data further includes primary color data for at least four primary color values, wherein the at least four primary color values include at least one white emitter;

wherein the at least one white emitter includes a first white emitter and a second white emitter, wherein the first white emitter and the second white emitter have different color temperature values;

wherein the at least one display device and the image data converter are in network communication; and

wherein the image data converter is operable to convert the set of image data for display on the at least one display device.

18. The system of claim 17 , wherein the at least one white emitter includes a mid-Kelvin white emitter.

19. The system of claim 18 , wherein the mid-Kelvin white emitter is modified to include a green bias.

20. The system of claim 17 , wherein the at least one white emitter includes at least one broadband white emitter.
