ABSTRACT:
An image processing apparatus performs processing to input an original image pattern composed of dots, detect contour dots from the inputted original image pattern, and identify a pattern of dot rows formed by the contour dots detected. Editing is performed with regard to the location of a dot row at which the identified pattern is a pattern to undergo editing, whereby the inputted original image pattern is converted into an image pattern represented by intermediate brightness. The image pattern so edited is outputted as by a printer.
