Image processing device performing the conversion of gradation values by means of error diffusion method
摘要
<p>When gradation values of an original image are converted, a pixel data read unit reads out a piece of pixel data, and a pixel data conversion unit converts the gradation value of the piece of pixel data. A condition judging unit decides whether a pixel corresponding to the piece of pixel data satisfies a predetermined condition, and a data conversion correction unit corrects by a stochastic process the conversion performed by the pixel data conversion unit when the condition judging unit decides that the piece of pixel data satisfies the predetermined condition.</p>
