COLOR ADJUSTMENT DEVICE AND COLOR ADJUSTMENT PROGRAM

摘要

PROBLEM TO BE SOLVED: To adjust a degree of accuracy of a three-dimensional LUT for color conversion to target accuracy.SOLUTION: A color adjustment device 1 comprises: a distance computation unit 17 for computing a difference between a tristimulus value of an optical sensor 3 measured when an image of an adjustment color is displayed in a display device 2, and a target tristimulus value stored in a storage unit 19; a control unit 16 for determining whether or not the difference satisfies a predetermined condition and, if it is determined that the difference satisfies the predetermined condition, setting a next adjustment color in an adjustment color generation unit 10; a repeated coefficient computation unit 15 for computing a repeated coefficient which is a correction coefficient of the target tristimulus value every time the predetermined condition is not satisfied; a temporary target value computation unit 14 for computing a temporary target value which is a value obtained by multiplying the repeated coefficient by the target tristimulus value; and a conversion unit for computing a set value by subjecting the temporary target value to predetermined conversion processing, and setting the set value in a three-dimensional LUT 20.SELECTED DRAWING: Figure 1
