ABSTRACT:
An image processing apparatus can obtain a copy image having excellent reproducibility with a relatively simple structure of a processing unit that processes image data. The image processing apparatus generates image formation data by processing image data. A gradation processing unit binarizes the image data according to an error diffusion process so as to convert the image data into binary image data. A character/line drawing detection unit determines whether a part of the binary image data corresponds to a character/line drawing portion that consists of characters or line drawings so as to detect the character/line drawing portion. An image processing unit applies an image processing to the part of the binary image data by using an image processing method according to a result of determination of the character/line drawing detection unit.
