ABSTRACT:
In a CRT calibration device, gradation signals of plural colors displayed on a CRT are determined in a gradation signal calculator based on a .gamma. value input from a keyboard and data from a luminance value storage unit storing a plurality of relative luminance values on the CRT. If a user wants to correct the .gamma. value while seeing the plural colors displayed on the CRT, he inputs a correct .gamma. value through the keyboard.
