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.

An embodiment of the disclosure provides a method and a system to sense a light source based on a viewer position in relation to display device. The system receives sensor data from one or more light sensors mounted on a wearable device worn by a viewer of a display device in a room, where a field of view for the light sensors covers at least a field of view of the viewer. The system identifies a light source perceived in a field of view of the viewer based on the sensor data. The system transmits data for one or more operations to be performed by the display device displaying content to the viewer to compensate for a change in brightness or color of the content caused by the light source based at least in part on light source information of the light source.

A method and system for color mapping digital visual content for improved viewing by a color vision deficient observer includes receiving the digital visual content to be color mapped, clustering color values of the digital visual content into a plurality of color clusters, assigning each color cluster to a respective one of a set of target color values in which the set of target color values have increased visual distinguishability for the color vision deficient observer; and for each color cluster, mapping the color values of the color cluster to the target color value, thereby generating a color-mapped digital visual content. One or more regions of interest of the content can be identified and the color mapping may be applied onto to those regions of interest.

A display device according to an embodiment of the present application comprises a storage configured to store gamut mapping data, a controller configured to, when an image signal is input, convert the input image signal into an output signal based on the gamut mapping data, and a display configured to display an image based on the output signal, wherein the controller changes the gamut mapping data according to the input image signal.

A handheld imaging device has a data receiver that is configured to receive reference encoded image data. The data includes reference code values, which are encoded by an external coding system. The reference code values represent reference gray levels, which are being selected using a reference grayscale display function that is based on perceptual non-linearity of human vision adapted at different light levels to spatial frequencies. The imaging device also has a data converter that is configured to access a code mapping between the reference code values and device-specific code values of the imaging device. The device-specific code values are configured to produce gray levels that are specific to the imaging device. Based on the code mapping, the data converter is configured to transcode the reference encoded image data into device-specific image data, which is encoded with the device-specific code values.
