Abstract: PROBLEM TO BE SOLVED: To obtain a smooth correction LUT capable of correcting gradation to make desired display characteristics by using a table for correcting gradation prepared based on the characteristics value, etc., of target gradation. SOLUTION: In order to measure the characteristics of a picture display device to calculate a characteristics curve, a prescribed test pattern is displayed on the device 12, a relation between data and a luminance value is measured by using a luminance meter 16; the value is inputted to the input part 18 of a personal computer 14. The characteristics value and the target setting value of the device 12 are converted to a logarithmic value by a log luminance converting part 20. Since these values are discrete data, an interpolating method for making continuous data is selected by an interpolating method selecting part 22 and an interpolation part 24 takes the logarithm of the luminance value to interpolate data values changed into a brightness value as a sample point.  A target set value is interpolated to obtain a target gradation curve and the characteristics value is interpolated to obtain a specific characteristics curve.
