<P>PROBLEM TO BE SOLVED: To improve precision in an output signal value (parameter) of a three-dimension lookup table. <P>SOLUTION: The three-dimension lookup table for color conversion which is provided to a display device acquires an output signal value of a target point by three-dimension interpolation by using an actually measured characteristic value of each lattice point of the three-dimension actually-measured characteristic that surrounds the target point if an ideal characteristic value related to the target point is surrounded with the actually measured characteristic value related to the three-dimension actually-measured characteristic, and then stores an output signal value corresponding to a input signal value. Since the noise component captured during an actual measuring process is removed at that time, the precision of an output signal value of the three-dimension lookup table is improved. <P>COPYRIGHT: (C)2012,JPO&INPIT |
