Abstract:
Various techniques for implementing aspects of color control in display devices are disclosed. One exemplary technique includes measuring an input/output profile of a display, then applying a mathematical model to the display's measured profile to generate color control tables. One exemplary technique may include tracking a first color temperature below a high-luminosity transition point and gradually transitioning to tracking a second color temperature above the high-luminosity transition point. One exemplary technique may also include gradually transitioning from tracking a darklight color temperature below a low-luminosity transition point to tracking the first color temperature above the low-luminosity transition point. Another exemplary technique may include tracking a response curve for a specified chromaticity above a low-luminosity transition point.
