Patent ID: 7190372

Claim:
A display characterization method comprising: receiving color characteristic adjustment variable values of a display set by a user; finding color characterization variable values corresponding to the received color characterization adjustment variable values from a lookup table storing combinations of color characterization adjustment variable values within a predetermined variation range and color characterization variable values corresponding to each combination of color characterization adjustment variable values, wherein the color characterization adjustment variable include brightness, contrast and white color temperature, and the color characterization variables include gamma with respect to R, G, and B channel and white points, and the gamma γ is obtained from the following equation: Y n =D n γ , D n represents the input signal of R, G, B channels divided by the maximum value of the input signal and Y n represents the output light intensity of the display divided by the maximum output light intensity of the display, the output light intensity of the display reflecting the color characteristic adjustment variable values of the display set by the user, and wherein the lookup table is populated in accordance with the gamma equation and white points measured at predetermined intervals of color temperature within the entire range of color temperature variations; and rewriting a display device's profile using the found color characterization variable values.
