  • Publication number: 20120182305
    Abstract: Disclosed herein is an image display device, including: a display block displaying thereon an image by using pixels disposed in a two dimensional matrix; and a gradation converting block executing gradation converting processing by using an error diffusion method, wherein the gradation converting block partitions an area in which the pixels are disposed into virtual partitions, and carries out the error diffusion when the gradation converting processing is executed with respect to the pixels within the virtual partition exclusively within the virtual partition, thereby carrying out gradation conversion for the image which is displayed on the display block.
