    • This invention obtains a high-quality output image in which a jaggy or a disconnection of a thin line hardly stands out. An edge detection unit detects whether the pixel of interest is an edge pixel or a non-edge pixel. A screen processing unit performs screen processing for the pixel of interest to determine the output value of the N-level tone. A calculation unit performs filtering processing having a preset visual sense characteristic for an area including the pixel of interest to calculate the target value of the pixel of interest, and corrects the value of the pixel of interest so as to come close to the target value, thereby determining the output value of the N-level tone. The selector selects, according to the detection result by the edge detection unit, either the result from the calculation unit or that from the screen processing unit.
    • 本发明获得了粗纱或细线的断开几乎不突出的高质量输出图像。 边缘检测单元检测感兴趣的像素是边缘像素还是非边缘像素。 屏幕处理单元对感兴趣的像素执行屏幕处理以确定N级音调的输出值。 计算单元对包括感兴趣像素的区域执行具有预设的视觉特性的滤波处理,以计算感兴趣像素的目标值,并且校正感兴趣像素的值以接近目标值, 从而确定N级音调的输出值。 选择器根据边缘检测单元的检测结果选择来自计算单元的结果或来自屏幕处理单元的结果。
