    • 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.
    • 图像处理装置包括用于将文档上的图像再现到记录介质上的处理单元和用于检测文档图像的状态的检测电路。 控制电路控制处理单元以预定的倍率再现原稿图像。 文档的状态可以包括文档上的图像的区域,文档图像是否与文档的边缘相邻,文档边缘的位置或文档的布置。 然后根据该特定状态的检测由控制电路控制文件图像的再现的放大率。 例如,如果确定文档图像与文档的边缘相邻,则将再现控制为缩小倍率。 如果文档被确定为远离参考位置,则可以擦除再现图像的一部分,使得仅重现实际文档图像而不是与文档相邻的不需要的背景。
