Claim:
1. A method of reducing a color moire using an image processor, the method comprising: calculating, by a local mean calculator, a plurality of local color mean values around a pixel in a selected region of a current image, the plurality of local color mean values comprising a first local color mean value of a first color, a second local color mean value of a second color, and a third local mean value of a third color; calculating, by the local mean calculator, difference values between the plurality of local color mean values, the difference values comprising a first difference value between the first local color mean value and the second local color mean value, a second difference value between the second local color mean value and the third local color mean value, and a third difference value between the first local color mean value and the third local color mean value; calculating, by the local mean calculator, a maximum difference value from among the difference values, the maximum difference value corresponding to a largest value among the first difference value, the second difference value, and the third difference value; and setting, by a weight setter, a moire correction weight to the pixel on the basis of the maximum difference value.
