Abstract:
1. A method for generating a gamma table, applied to a display, the display obtaining n-bit corrected gray levels [y(1), . . ., y(2 m )] from m-bit original gray levels [x(1), . . . , x(2 m )] by using the gamma table, m and n being positive integers, the method comprising: (a) calculating the corrected gray levels [y(1), . . . , y(2 (b) successively calculating differences of two adjacent corrected gray levels (y(i+1)−y(i)) and recording the differences as a plurality of gamma reference values z(i+1) (i=1˜(2m−1)) corresponding to the original gray levels x(i+1), in which the value z(1) corresponding to x(1) is y(1), in order to generate the gamma table.
