Patent ID: 7495679

Claim:
A system for calibrating a display device to improve its perceived image quality, the system comprising: a calibration module that is configured to: determine, for each of a plurality of white colors associated with a plurality of gray levels displayed sequentially by the display device, a measured chromaticity point on a chromaticity diagram and a measured luminance level; calculate, for each gray level, a differential change in each primary color component value 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 calculate correction values for each primary color component and each gray level based on the calculated differential changes; and means for outputting to the display device the calculated correction values, wherein the primary color components of a color video signal received by the display device are corrected based on the calculated correction values such that the display device accurately reproduces luminance and color properties of the color video signal.
