Abstract:
Various methods, systems, and apparatus for implementing aspects of color control in display devices are disclosed. One such method 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 such method 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 such method 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 such method may include tracking a response curve for a specified chromaticity above a low-luminosity transition point. One apparatus according to aspects of the present invention includes means for measuring an input/output profile of a display, and means for applying a mathematical model to the display's measured profile to generate color control tables. One such apparatus may include means for tracking a first color temperature below a high-luminosity transition point and for gradually transitioning to tracking a second color temperature above the high-luminosity transition point. One such apparatus may also include means for 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 such apparatus may include means for tracking a response curve for a specified chromaticity above a low-luminosity transition point.
