Abstract:
A system for constructing a display device model that characterizes the calorimetric response of a display device, the system comprising:a color measuring instrument configured and arranged to obtain color values from a set of color patches; anda computer arrangement configured and arranged to construct the display device model as a function of the color values, the display device model havingan analytic mixing model constructed as a function of a type of the display device, the analytic mixing model including one or more mathematical equations that define mixing of multiple colors, anda multi-dimensional lookup table comprising a set of entries, the lookup table being constructed and arranged to compensate for certain colorimetric characteristics of the display device resulting from interaction of different color channels by receiving a set of indices, providing a set of adjusted values, and applying the adjusted values as inputs to the analytic mixing model.
