摘要： A method for creating a Gamma look-up table (LUT) includes: calculating interpolated display characteristics of a plurality of colors by using a nonlinear interpolation algorithm based on a plurality of display characteristics of the predetermined patterns wherein the number of the display characteristics is smaller than the product of the number of the colors and the number of the interpolated display characteristics of the colors; and correcting the interpolated display characteristics of the colors on the basis of a maximum display characteristic value and a reference gamma value so that the Gamma look-up table is created. The predetermined patterns comprise a plurality of gray level patterns which one-by-one correspond to a plurality of levels, and the interval of a pair of adjacent gray level patterns among the gray level patterns is different from the interval of another pair of adjacent gray level patterns among the gray level patterns.
