    摘要: 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.

    摘要翻译: 当原始图像的灰度值被转换时,像素数据读取单元读出一个像素数据,并且像素数据转换单元转换该像素数据的灰度值。 条件判断单元判定与该像素数据对应的像素是否满足预定条件,并且数据转换校正单元在状态判断单元判定为一个 像素数据满足预定条件。
