摘要： At least certain embodiments of the disclosures relate to methods for performing color correction on systems having at least application that is not color managed. In one embodiment, a method to perform color correction on a system includes determining a threshold gamut. Then, the system determines whether a real gamut exceeds the threshold gamut. The system color corrects input color if the real gamut exceeds the threshold gamut. Color correcting may include adjusting input color in the system. In another embodiment, a system includes memory to store color data for at least one non-color managed application and to store color data for at least one color managed application. The system includes a display device to display the color data. The system includes one or more graphics processing unit that are configured to execute instructions to color correct input color when a real gamut value exceeds a threshold gamut value.

摘要： An automated RAW image processing method and system are disclosed. A RAW image and metadata related to the RAW image are obtained from a digital camera or other source. The RAW image and the related metadata are automatically processed using an Operating System service of a processing device to produce a resulting image in an absolute color space. When automatically processing, a predetermined tone reproduction curve is applied to the interpolate RAW image to produce the resulting image. The predetermined tone reproduction curve is derived from a plurality of reference images and is selected based on the metadata associated with the RAW image. The resulting image is then made available to an application program executing on the processing device through an application program interface with the Operating System service.

摘要： A display color-correcting system is provided. Color response values are measured that go into the vertices of polyhedra in a cubic color output space of the display. A set of corresponding values for the display is built from intermediate values determined between the measured color response values. The intermediate values are determined by decomposition and interpolation of interpolation volumes in the cubic color output space. Each of the interpolation volumes is the combined volume of a selected polyhedron within the cubic color output space and a predetermined volume of space between the selected polyhedron and the next polyhedron within the cubic color output space. The set of corresponding values is converted into decoupled RGB adjustment values that specify the RGB signals independently for the display to produce corrected colors. The RGB adjustment values are saved into one or more look-up tables.

摘要： White point is corrected without degrading luminance on a display device. A white point manager modifies the balance between red, green and blue according to a target white point up to a threshold gray value. As the gray scale approaches white from the threshold gray value, the white point manager blends the balance between red, green and blue from the target white point substantially towards the native white point for the display device, so as not to degrade luminance as the gray scale approaches white.

摘要： Methods and apparatuses for performing gamma corrections to maintain a plurality of colors substantially consistent with a color point. In one aspect of the present invention, a method to generate correction functions for performing color correction for a device for signals of different color components in a color space includes: generating a first correction function for a first color component in the color space; and generating second correction functions for second color components in the color space by reducing first color differences between a target white point and white points of a plurality of grays corrected by the first and second correction functions. The second color components are the color components in the color space other than the first color component. The first color differences are minimized relative to a chromaticity diagram.

摘要： Methods and data processing systems are disclosed for color management in a multiple display system. In one embodiment, a computer-implemented method includes color managing media based on a color gamut of a first display. Then, the method mirrors the media in a mirrored mode onto the first display and a second display. Then, the method processes the media for the second display through a gamma information for the second display. The gamma information is for a non-mirrored mode for the second display. The first and second displays may have different color gamuts. These color gamuts can be used for generating or modifying the gamma information for the second display. The gamma information may provide a color management for the second display that is based on the second display and is independent of the first display.
