ABSTRACT:
There are provided an image processing method and apparatus for processing an image by digital signals and for reproducing the image with a high picture quality. The apparatus comprises: an input device to input a plurality of color image data; a first processor to perform a dotting process on the color image data input by the input device; and a second processor to digitize the color image data dot-processed by the first processor, wherein the first processor changes the dotting process for each of the color image data. With the apparatus, first and second features of the input image are detected and different dotting processes are executed in accordance with the first and second features, so that the image process can be executed at a high speed and a color image having excellent gradations and resolution can be obtained while suppressing the occurrence of a color moire.
