Claim 3:
4. The color modulation method according to claim 1, wherein calculating the group of RGB mapped data corresponding to the group of original RGB data using the group of original RGB data, the plurality of groups of selected RGB data and the group of RGB mapped data corresponding to each group of selected RGB data, in combination with the predetermined interpolation algorithm includes:
determining a segment that the R value included in the group of original RGB data is in in the M selected R values, a segment that the G value included in the group of original RGB data is in in the O selected G values, and a segment that the B value included in the group of original RGB data is in in the P selected B values according to the group of original RGB data and the plurality of groups of selected RGB data;
determining a group of first target RGB data according to small endpoint values of segments that the R value, the G value and the B value in the group of original RGB data are respectively in;
determining a group of second target RGB data according to large endpoint values of the segments that the R value, the G value and the B value in the group of original RGB data are respectively in; and
calculating the group of RGB mapped data corresponding to the group of original RGB data using the predetermined interpolation algorithm in combination with the group of original RGB data, a group of RGB mapped data corresponding to the group of first target RGB data and a group of RGB mapped data corresponding to the group of second target RGB data.
