    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.

    摘要: A method for adjusting the characteristics of a display. The method for adjusting the characteristics of the display may include constructing color models as a function of a parameter such as temperature. Furthermore, the color model may be used to determine adjustment values to be applied to a display. The adjustment values may be organized in a table as a function of temperature and color values. The adjustment values may be determined from measurements.

    摘要: The described embodiments provide a system that facilitates a switch from using a first graphics-processing unit (GPU) to using a second GPU to drive a display. During operation, upon generation of a request to switch from using the first GPU to using the second GPU as a signal source for driving the display, the system obtains a transform (such as a lookup table) that enables the displayed color output from the second GPU to substantially match the displayed color output from the first GPU. The system then makes the transform available for use by the second GPU in driving the display.

    摘要: Some embodiments of the invention provide novel methods for converting the color region of images. For instance, the method of some embodiments converts the color of an image from one color region (e.g., from a Rec. 601 color region) to another color region (e.g., to a Rec. 709 color region). In some embodiments, the method receives the image in a first color format that is non-linearly encoded within a first color region. Without performing a linearization operation to linearize the color component values of the image, the method then converts the image into a second color format that is defined with respect to a second color region. In some embodiments, the color-converted image is non-linearly encoded in the second color region.
