Abstract
The present invention includes 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 an image signal, comprising:
- at least one processor coupled to at least one memory;
- a graphics processing unit (GPU);
- and
- a display engine;
- wherein the GPU and the display engine are in communication;
- wherein image data related to the image signal is input into the GPU;
- wherein the GPU is operable to process the image data, thereby creating rendered image data;
- wherein the image data corresponds to a set of values in an International Commission on Illumination (CIE) xyY color space, and wherein the set of values in the CIE xyY color space includes two colorimetric coordinates (x and y);
- wherein the rendered image data is transmitted to the display engine;
- wherein the transmitted rendered data includes processed xyY data, wherein the processed xyY data includes a first channel related to a first colorimetric coordinate (x) of the two colorimetric coordinates (x and y), and a second channel related to a second colorimetric coordinate (y) of the two colorimetric coordinates (x and y);
- wherein the display engine is operable to process the rendered image data, thereby creating formatted image data;
- and
- wherein the formatted image data is operable to be transmitted to at least one viewing device.
A system for displaying an image signal, comprising:
- at least one processor coupled to at least one memory;
- a graphics processing unit (GPU);
- and
- a display engine;
- wherein the GPU and the display engine are in communication;
- wherein the display engine includes a raster scaler, at least one video display controller, at least one image data converter, a scaler and/or limiter, a multi-column three-dimensional (3D) look-up table (LUT), a non-linear function and/or tone curve applicator, a sampling selector, a video bus, and/or at least one output formatter and/or encoder;
- wherein image data related to the image signal is input into the GPU;
- wherein the GPU is operable to process the image data, thereby creating rendered image data;
- wherein the image data corresponds to a set of values in an International Commission on Illumination (CIE) xyY color space;
- wherein the rendered image data is transmitted to the display engine;
- wherein the display engine is operable to process the rendered image data, thereby creating formatted image data;
- and
- wherein the formatted image data is operable to be transmitted to at least one viewing device.
