ABSTRACT:
An image processing apparatus includes a process unit for reproducing an image on a document onto a recording medium and a detection circuit for detecting the status of the document image. A control circuit controls the process unit to reproduce the document image at a predetermined magnification. The status of the document may include the area of the image on the document, whether the document image is adjacent an edge of the document, the location of the edge of the document, or the disposition of the document. The magnification of reproduction of the document image is then controlled by the control circuit in accordance with the detection of that particular status. For example, if it is determined that the document image is adjacent the edge of the document, reproduction is controlled to be at reduced magnification. If the document is determined to be away from a reference position, a portion of the reproduced image may be erased so that only the actual document image is reproduced rather than unwanted background adjacent the document.
