ABSTRACT:
The present invention is directed to an image processing device that can prevent the occurrence of moire patterns when processing a dot image. An image processing device according to the present invention comprises an image memory for storing multi-gradational image data, an area-deciding portion for deciding an area of pixels PIX (x, y) of a multi-gradational image stored in the memory and outputting a decision signal SEL=0 when the pixel is a character area pixel or a decision signal SEL=1 when the pixel is a halftone area, a binarizing portion for character for binarizing a character image pixel PIX (x, y) of the multi-gradational image data stored in the memory and outputting a binarized image data L, a binarizing portion for photograph for binarizing a halftone image pixel PIX (x, y) of the multi-gradational image data stored in the memory and outputting a binarized image data P, an output selecting portion for selectably outputting binarized image data B which is the binarized image output L from the binarizing portion for character when the output SEL of the area deciding portion is 1 or the binarized image output P from the binarizing portion for photograph when the output SEL is 0, and a memory for storing binarized image data outputted from the output selecting portion.
