ABSTRACT:
An image processing apparatus determines an image data of a selected area to be an image such as of characters having no halftone or an image such as of a photograph having halftones. An image processing mode optimal to the image data of the selected area is assigned to this area as attribute data. Based on the attribute data, the image data of the selected area is processed in the optimal mode. Each of such area includes at least one pixel, and an overall result of image processing carried out in respective optimal modes is output.
