In one embodiment, a computing system may receive a target color and a propagated error for a pixel location. The system may determine an error-modified target color for the pixel location based on the received target color and the propagated error. The system may identify, based on a location of the error-modified target color in a three-dimensional color space, a subset of pre-determined colors in the three-dimensional color space. The error-modified target color may correspond to a weighted combination of the subset of pre-determined colors. The system may determine a pixel color for the pixel location based on the subset of pre-determined colors and respective weights associated with the subset of pre-determined colors. The system may determine, based on the pixel color, driving signals for light-emitting elements associated with the pixel location. The system may output the driving signals to control the light-emitting elements associated with the pixel location.

An object of the present invention is to reduce computation for color conversion processing on input RGB color signals with maintaining the hue of a picture expressed by the input RGB color signals. A color conversion processor of the present invention includes: a conversion unit that converts color data including multiple color components, which can be displayed in a first color gamut, to corresponding color data in a second color gamut, which is narrower than the first color gamut; a first color correction unit that corrects the converted color data by using a first color correction value; a first derivation unit that derives a first luminance correction value by multiplication using the first color correction value; and a first luminance correction unit that corrects the color data, corrected by the first color correction unit, by using the first luminance correction value.

The present disclosure provides a data driving circuit and a driving method thereof, a data driving system and a display device. In an embodiment of a data driving circuit, each digital to analog conversion unit is only used for driving sub-pixels of one color, and by controlling on-off of the switch unit, one data line interface unit is enabled to be connected to different digital to analog conversion units when driving sub-pixels of different colors. In this way, a reference voltage can be provided to the digital to analog conversion unit for driving different color display by a single physical Gamma circuit, without having to use a digital Gamma circuit. Therefore, gray scale loss caused by adjustment using the digital Gamma circuit can be avoided fundamentally.

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. A six-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.

A system for image enhancement on digital display device is disclosed. The system includes an image processing subsystem including a digital art metadata collection module to measure the ambient condition on a digital art piece using sensors. The digital art metadata collection module collects a set of metadata corresponding to the digital art piece by analysing the ambient condition. The image processing subsystem includes an image adjustment module to modify parameters on digital display device based on the set of metadata using one or more image processing techniques. The image adjustment module generates a target digital image representative of a printed image quality based on the modified parameters.
