1. A method to compensate for eye tracking characteristics, comprising: generating a motion vector according to a first frame image signal Si and a second frame image signal, the first frame image signal Si and the second frame image signal received as an input image signal, the second frame image signal displayed before the first frame image signal Si; adjusting the pixel values of the first frame input image signal Si according to the direction and magnitude of the motion vector, wherein pixel values are adjusted, at least in part, based on the average of the first frame image signal Si and one or more resultant image signals that result from the incremental displacement of the first frame image signal Si in the same direction as the motion vector; and displaying a third image signal So according to the adjusted pixel values.
