1. A display device comprising:
a display configured to output image data; and
a controller configured to:
extract a contour noise removal region from the image data;
acquire motion information of the image data; and
remove contour noise based on a de-contour gain value corresponding to the motion information,
wherein the controller is further configured to remove the contour noise based on a de-contour gain table to which the de-contour gain value corresponding to the motion information is mapped,
wherein the de-contour gain table includes a plurality of mapping coordinates,
wherein first coordinates among the plurality of mapping coordinates have a first de-contour gain value corresponding to a first motion information value,
wherein second coordinates among the plurality of mapping coordinates have a second de-contour gain value corresponding to a second motion information value, and
wherein when the first motion information value is greater than the second motion information value, the first de-contour gain value is smaller than the second de-contour gain value.
