Abstract

Systems and methods for displaying super saturated color. Image data for display on a display or viewing device with a potential white luminance in a standard system with a maximum luminance is processed such that colors near the white point are reduced to a limited luminance. As the chroma of the displayed color is increased, a luminance attenuation is decreased. The scaling of the reduction is operable to be a linear function, a non-linear function, or any other function.

Claims (45)

1 . 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 two colorimetric coordinates and a luminance;

an image data converter operable to encode and decode the set of values in the color space; and

at least one viewing device;

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

wherein the encode and the decode includes transportation of processed data;

wherein the processed data includes data related to a relative luminance and the two colorimetric coordinates;

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

wherein the at least one viewing device is operable to display the primary color system based on the set of image data; and

wherein the relative luminance increases as a distance of a chroma of the two colorimetric coordinates increases from a neutral point or a white point of the at least one viewing device.

2 . The system of claim 1 , wherein the primary color system displayed on the at least one viewing device is based on the set of image data.

3 . The system of claim 1 , wherein the image data converter is operable to convert the set of primary color signals to the set of values in the color space.

4 . The system of claim 1 , wherein the image data converter is operable to convert the set of values in the color space to a plurality of color gamuts.

5 . The system of claim 1 , wherein the image data converter is operable to fully sample the processed data related to the relative luminance and subsample the processed data related to the two colorimetric coordinates.

6 . The system of claim 1 , wherein the processed data related to the relative luminance and the two colorimetric coordinates are fully sampled.

7 . The system of claim 1 , wherein a white value corresponds to the white point of the at least one viewing device.

8 . The system of claim 1 , wherein the encode includes converting the set of primary color signals to XYZ data and then converting the XYZ data to create the set of values in the color space.

9 . The system of claim 1 , wherein the decode includes converting the processed data to XYZ data and then converting the XYZ data to a format operable to display on the at least one viewing device.

10 . The system of claim 1 , wherein the luminance is converted to the relative luminance using at least one linear function, at least one non-linear function, or at least one lookup table (LUT).

11 . The system of claim 1 , wherein the relative luminance is equal to or lower than the luminance.

12 . The system of claim 1 , wherein the encode includes scaling of the two colorimetric coordinates, thereby creating scaled colorimetric coordinates, and wherein the decode includes rescaling of the scaled colorimetric coordinates.

13 . The system of claim 1 , wherein the encode includes application of a data range reduction function with a value between about 0.25 and about 0.9 and the decode includes application of an inverse data range reduction function with a value between about 1.1 and about 4.

14 . The system of claim 1 , wherein the primary color system is a Red, Green, and Blue (RGB) primary system or a multi-primary system.

15 . The system of claim 1 , wherein the white point of the at least one viewing device has a limited luminance.

16 . The system of claim 1 , wherein the image data converter does not modify primary colors within a specified hue angle range and a specified chroma range.

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

an image data converter operable to encode and decode a set of values corresponding to a set of primary color signals in a color space; and

at least one viewing device;

wherein the set of values in the color space includes two colorimetric coordinates and a luminance;

wherein the at least one viewing device is operable to receive data from the image data converter;

wherein the encode and the decode includes transportation of processed data;

wherein the processed data includes data related to a relative luminance and the two colorimetric coordinates;

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

wherein the at least one viewing device is operable to display the primary color system based on the set of image data; and

wherein the relative luminance increases as a distance of a chroma of the two colorimetric coordinates increases from a neutral point or a white point of the at least one viewing device.

18 . The system of claim 17 , wherein the luminance is converted to the relative luminance using at least one linear function, at least one non-linear function, or at least one lookup table.

19 . 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, wherein the set of values in the color space includes two colorimetric coordinates and a luminance;

encoding the set of image data in the color space;

decoding the set of image data in the color space; 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 data, wherein the processed data includes data related to a relative luminance and the two colorimetric coordinates;

wherein the at least one viewing device is operable to display the primary color system based on the set of image data; and

wherein the relative luminance increases as a distance of a chroma of the two colorimetric coordinates increases from a neutral point or a white point of the at least one viewing device.

20 . The method of claim 19 , wherein the luminance is converted to the relative luminance using at least one linear function, at least one non-linear function, or at least one lookup table (LUT).
