ABSTRACT:
An image processing device is provided with a scanning means which performs subscanning by a pitch corresponding to a width covering a number of pixels less than the number of detectable pixels by a one dimensional image sensor by two or more pixels so as to overlap two or more line pixels. An edge emphasizing means performs an edge emphasis processing for the pixels from the second pixel to the second last pixel according to the image data obtained in response to the scanning by the scanning means.
