<P>PROBLEM TO BE SOLVED: To improve the accuracy of white balance adjustment and shorten an adjustment time required for the white balance adjustment in an image display device. <P>SOLUTION: A liquid crystal television as an image display device comprises LUTs 35R, 35G, and 35B as tables of correction data for correcting color balance of an image to be displayed and a microcomputer 12. The microcomputer 12 recalculates and rewrites the correction data of the LUTs 35R, 35G, and 35B based on an input value InL of image data of a Low side adjustment image, an input value InH of image data of a High side adjustment image, a gain value GainL to be provided to the input value InL of the image data of the Low side adjustment image so that color balance of the Low side adjustment image becomes predetermined color balance, and a gain value GainH to be provided to the input value InH of the image data of the High side adjustment image so that color balance of the High side adjustment image becomes predetermined color balance. <P>COPYRIGHT: (C)2012,JPO&INPIT |
