12. An image compensation method for a display device, the image compensation method comprising:
generating captured luminance data including luminances of a plurality of pixels of a display panel corresponding to one of captured grayscales included in a plurality of grayscales;
generating measured luminance data including luminances of a plurality of areas of the display panel corresponding to a measured grayscale other than the captured grayscales among the grayscales;
calculating compensation grayscale data for the measured grayscale based on the captured luminance data, the measured luminance data, and input grayscale data for the measured grayscale;
generating output grayscale data based on the input grayscale data and the compensation grayscale data; and
providing a data voltage generated based on the output grayscale data to the display panel.
