1. A machine implemented method of compensating an image of a display panel, the method comprising: measuring luminance and color of a plurality of full pattern images, the full pattern image including a single full grayscale; measuring luminance and color of a multi pattern image, the multi pattern image including a plurality of multi grayscales; generating a first compensating value to displace a position of a multi grayscale region in the multi pattern image to a central portion of the multi pattern image; and compensating luminance and color of the display panel based on the luminance and the color of the full pattern image, the luminance and the color of the multi pattern image and the first compensating value.
