<p>An image processing apparatus including an input circuit (12) for receiving image data, a binarizing unit (14) for binarizing a subject pixel of the image data supplied from the input circuit (12), an error detector (16) for detecting an error between a binarized image data obtained by the binarizing unit (14) and the image data, an error diffusing circuit (20, 22, 24) for diffusing the error on other image data associated with other pixels around the subject pixel, a compensating unit (10) for compensating the image data of the subject pixel by using a compensation data which is caused by a previous error diffusion of the diffusing circuit (20, 22, 24), a circuit (26, 32, 34) for detecting an image density of the image data for a prescribed image area surrounding the subject pixel and a controller (30) for controlling the compensating unit (10) in response to the image density detected by the detecting circuit (26, 32, 34).</p> |
