Abstract: Techniques are disclosed relating to additive color systems. In one embodiment, an apparatus is disclosed that includes a device configured to operate on pixel data having color component values falling within an extended range outside of 0.0 to 1.0 corresponding to an extended range color space. In one embodiment, a gamma correction function is disclosed that can be applied to the pixel data, where the gamma correction function is applicable to both negative and positive values. Various embodiments of formats for arranging pixel data are also disclosed.

Abstract: A method of adjusting the color characteristics of a display. The method 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 of luminance and chrominance taken at specific temperatures. The RGB value (515) may be taken at a particular temperature (T1). This measured temperature (510) may be used to determine the corresponding adjustment value in the RGB table (520) or a new adjustment value may be calculated for the temperature (T 1) by interpolating the data provided in the RGB table (520).
