Abstract
An error diffusion unit generates difference error addition data by adding, to pixel data of a target pixel among pixels in a display element, neighboring error data and difference error data of a pixel processed immediately before, and generates error diffusion data using data on a high-order bit amide of the difference error addition data. The error diffusion unit calculates error data of the target pixel using data on a low-order bit side of the difference error addition data, and calculates difference error data to be added to pixel data of a pixel to be processed subsequently, using a difference between the error data of the target pixel and the error data of the neighboring pixels.
