Abstract
An image display device includes a first pixel data calculator calculating first pixel data for a pixel of attention based on a first error value for a pixel adjacent thereto in the same error diffusion block; a second pixel data calculator calculating second pixel data for the pixel of attention based on a corrected error value for the adjacent pixel; a first error value calculator calculating the first error value based on the first pixel data; a second error value calculator calculating a second error value based on the second pixel data; and a corrected error value calculator calculating the corrected error value by correcting the second error value in a direction in which the second error value approaches the first error value in accordance with whether the pixel of attention is located within a predetermined range from a border among a plurality of error diffusion blocks.
