Method and system for automatically calibrating a color display
A system for calibrating a display device to improve its perceived image quality includes a calibration module configured to determine, for each of a plurality of white colors associated with a plurality of gray levels, a measured chromaticity point on a chromaticity diagram and a measured luminance level. The calibration module calculates, for each gray level, a differential change in each primary color component that simultaneously moves the measured chromaticity point to a target chromaticity point and adjusts the measured luminance level to a target luminance level on a predetermined luminance curve having a target gamma value, and calculates correction values for each primary color component and each gray level based on the calculated differential changes. The system also includes means for outputting the calculated correction values to the display device, which corrects the primary color components of a color video signal based on the calculated correction values.
