<P>PROBLEM TO BE SOLVED: To drastically reduce the number of correction data stored for three-dimensional correction. <P>SOLUTION: The image display device includes: a horizontal direction correction factor LUT (12) for storing and outputting a horizontal direction correction factor Kx corresponding to a horizontal position x; a vertical direction correction factor LUT (22) for storing and outputting a vertical direction correction factor Ky corresponding to a vertical position y; a gray level direction correction factor LUT (32) for storing and outputting a gray level direction correction factor Kp corresponding to a gamma-corrected gray level value P(z); a correction arithmetic operation unit (40) for performing correction to satisfy a three-dimensionally-corrected gray level value Q(x, y, z)=äKx(x)×Ky(y)×Kp(P(z))+1-Kp(P(z))}×(P(z)); and an image display unit (2) for displaying an image based on the three-dimensionally-corrected gray level value Q. Thus, circuit scale is reduced and adjustment man-hour for setting the correction data is drastically reduced. <P>COPYRIGHT: (C)2011,JPO&INPIT |
