    Abstract: An image processing apparatus obtains image data with a low resolution by processing a plurality of pixel values read in with a high resolution into one pixel value, for the low resolution mode. Thereby, the image processing apparatus is able to transmit unfailingly image data needed for reproduction of a narrow line in a document even during a low-resolution mode. Further, in accordance with a resolution mode that is currently selected, an image processing apparatus adjusts the ratio between the amount of edge enhancement with respect to the main scanning direction and the amount of edge enhancement with respect to the sub-scanning direction, thus unfailingly including the image data needed for reproduction of a narrow line extending in the main and/or sub-scanning direction.

    Abstract: An image processing machine processes image data of a letter document into binary data which are then put through smoothing-out processing, and image data of a photograph document into binary data by a method in which the optical density of a document is retained, in order to provide high-quality, smooth binary images of both letter documents and photograph documents. One memory stores data both for smoothing-out processing in the case of a letter document and for binary-processing in the case of a photograph document. The memory is used selectively for either type of processing. Thus, circuitry for the processing is simplified.
