Abstract
The image display device disclosed detects areas including grayscales with gradients and motions in an image signal and compensates the prescribed grayscales of the image signals to the other grayscales according to the motion amplitude and direction of the area, and the gradient amplitude and direction of the grayscale. Consequently, intermediate non-lit sub-fields causing the dynamic false contour are distributed to display image suppressing the dynamic false contour.
