PROBLEM TO BE SOLVED: To provide a color calibrator of a display device, calibrating a crosstalk between a plurality of colors and improving quality of a display video.SOLUTION: A color calibrator comprises a color estimator for receiving a plurality of data values of original color of a video signal. The color estimator comprises a first operator, a gray level electrical/optical converter, a mixed color electrical/optical converter, an original color electrical/optical converter, a plurality of linear converters, and a weighting calculator. The gray level electrical/optical converter, the mixed color electrical/optical converter, and the original color electrical/optical converter convert a gray level data value, a mixed color data value, and an original color data value, and generate a plurality of converted outputs, on the basis of a plurality of gray level conversion curves, a plurality of mixed color conversion curves, and a plurality of original color conversion curves. The weighting calculator receives conversion output and a plurality of weighting values, and generates an analysis output signal.
