    • In an image conversion method, a value which reflects the mutual relationship between the classes of pixel patterns each formed from a pixel classified as one of a plurality of classes and peripheral pixels is set as a converted value corresponding to each of the plurality of classes, a pixel of interest is sequentially selected from the input image, and a pixel pattern formed from the selected pixel of interest and a predetermined number of pixels around it is classified as one of the plurality of classes in accordance with a neighboring pattern obtained based on the relationship between the value of the pixel of interest and the values of peripheral pixels located at predetermined relative positions with respect to the pixel of interest. The value of the pixel of interest is converted into a converted value set for a class to which the pixel of interest has been classified.
    • 在图像转换方法中,反映从分类为多个类别和周边像素之一的像素形成的像素图案的类别之间的相互关系的值被设置为与多个类别中的每一个对应的转换值, 从输入图像顺序选择感兴趣的像素,并且根据所选择的感兴趣像素形成的像素图案和其周围的预定数量的像素被分类为根据基于 感兴趣像素的值与位于相对于感兴趣像素的预定相对位置的周边像素的值之间的关系。 感兴趣像素的值被转换为对感兴趣的像素已被分类的类的转换值集合。
