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. 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.

First claim

1 . A system for displaying a multi-primary color system, comprising:
a set of image data, wherein the set of image data includes a first set of color channel data and a second set of color channel data; an image data converter; a set of saturation data corresponding to the set of image data, wherein the set of saturation data is used to extend a set of hue angles for the first set of color channel data and the second set of color channel data; a set of Session Description Protocol (SDP) parameters, wherein the set of SDP parameters is modifiable; and at least one display device; 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 image data converter further includes a cyan primary position, and wherein the cyan primary position is positioned to limit saturation.

3 . The system of claim 1 , wherein the image data converter further includes a cyan primary position, and wherein the cyan primary position is determined by expanding the set of hue angles.

4 . The system of claim 1 , wherein the set of image data includes a bit level, wherein the image data converter is operable to convert the bit level of the set of image data, thereby creating an updated bit level.

5 . The system of claim 1 , wherein once the set of image data has been converted by the image data converter for the at least one display device, the set of SDP parameters is modified based on the conversion.

6 . The system of claim 1 , wherein the at least one display device is operable to display the multi-primary color system based on the set of image data.

7 . The system of claim 1 , further including at least one electronic luminance component, wherein the at least one electronic luminance component is not calculated within the at least one display.

8 . The system of claim 1 , wherein the first set of color channel data includes a first bit value defining black and a second bit value defining white, wherein the second set of color channel data includes a third bit value defining black and a fourth bit value defining white.

9 . The system of claim 1 , further including at least one transfer function (TF) for processing the set of image data.

10 . The system of claim 1 , further including a magenta primary value, wherein the magenta primary value is derived from the set of image data, and wherein the magenta primary value is not defined as a wavelength.

11 . A system for displaying a multi-primary color system, comprising:
a set of image data, wherein the set of image data includes a first set of color channel data and a second set of color channel data, wherein the set of image data further includes a bit level; an image data converter; at least one transfer function (TF) for processing the set of image data; a set of saturation data corresponding to the set of image data, wherein the set of saturation data is used to extend a set of hue angles for the first set of color channel data and the second set of color channel data; a set of Session Description Protocol (SDP) parameters, wherein the set of SDP parameters is modifiable; and at least one display device; wherein the at least one display device and the image data converter are in network communication; wherein the image data converter further includes a cyan primary position; and wherein the image data converter is operable to convert the set of image data for display on the at least one display device.

12 . The system of claim 11 , wherein the cyan primary position is positioned to limit saturation.

13 . The system of claim 11 , wherein the cyan primary position is determined by expanding the set of hue angles.

14 . The system of claim 11 , wherein once the set of image data has been converted by the image data converter for the at least one display device, the set of SDP parameters is modified based on the conversion.

15 . The system of claim 11 , wherein the at least one display device is operable to display the multi-primary color system based on the set of image data.

16 . A system for displaying a multi-primary color system, comprising:
a set of image data, wherein the set of image data includes a first set of color channel data and a second set of color channel data, wherein the set of image data further includes a bit level; 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; a set of saturation data corresponding to the set of image data, wherein the set of saturation data is used to extend a set of hue angles for the first set of color channel data and the second set of color channel data; a set of Session Description Protocol (SDP) parameters, wherein the set of SDP parameters is modifiable; and at least one display device; wherein the at least one display device and the image data converter are in network communication; wherein the image data converter is operable to convert the set of image data for display on the at least one display device.

17 . The system of claim 16 , wherein the image data converter further includes a cyan primary position, and wherein the cyan primary position is positioned to limit saturation.

18 . The system of claim 16 , wherein the image data converter further includes a cyan primary position, and wherein the cyan primary position is determined by expanding the set of hue angles.

19 . The system of claim 16 , wherein once the set of image data has been converted by the image data converter for the at least one display device, the set of SDP parameters is modified based on the conversion.

20 . The system of claim 16 , wherein the at least one display device is operable to display the multi-primary color system based on the set of image data.
