Abstract
An image display device such as an LCD television comprises a microcomputer and LUTs (look-up tables) which are tables of correction data for correcting color balance of an image to be displayed. The microcomputer recalculates correction data in the LUTs and updates the correction data to the recalculated correction data based on: an input value InL of image data of a Low side white balance adjustment image; an input value InH of image data of a High side white balance adjustment image; and a gain value GainL and a gain value GainH which are provided to the input value InL and the input value InH, respectively, to bring color balance of the Low side white balance adjustment image and the High side white balance adjustment image to a predetermined color balance, respectively.
