摘要： A user designates a two-sided copying mode, a reduced-scale copying mode, a vertical or horizontal binding direction, and the like from a control panel. An original image is magnification-varied at a designated reduction magnification, and the reduced image is stored in a page memory. In the case of an odd page (front surface) in a single-sided or two-sided copying mode, a &ggr; conversion circuit reads out and outputs stored image data in the normal order, thus forming images. On the other hand, in the case of an even page (back page) in the two-sided copying mode, whether the horizontal or vertical binding direction is designated is checked. If the binding direction agrees with the reversing axis direction of a paper sheet upon copying, images are read out in the normal order. When the vertical binding direction is designated, images are read out in an order opposite to the normal order, so that each page is rotated through 180°. Images are copied in the designated layout.
摘要翻译： 用户从控制面板指定双面复印模式，缩小尺寸复印模式，垂直或水平装订方向等。 原始图像以指定的缩小倍率进行放大变化，并且缩小图像被存储在页面存储器中。 在单面或双面复印模式下为奇数页（正面）的情况下，伽马转换电路以正常顺序读出并输出存储的图像数据，从而形成图像。 另一方面，在双面复印模式下的偶数页（背页）的情况下，是否指定了水平或垂直装订方向。 如果装订方向与纸张的反转轴方向一致，则以正常顺序读出图像。 当指定垂直装订方向时，以与正常顺序相反的顺序读出图像，使得每页旋转180°。 图像在指定的布局中复制。

摘要： A PDL interpreter rasterizes image data, which are described in page description language, entered from a host computer, and stores the rasterized image data in an image memory. A CPU discriminates the type of image, pixel by pixel, by referring to the image data stored in the image memory, and stores a discrimination code, which indicates the result of discrimination, in a code memory. The CPU reads out image data that have been stored in the image memory and reads the discrimination code corresponding to these image data out of the code memory. The image data read out of the image memory are subjected to different binarizing processing by two binarizing circuits. Depending upon the discrimination code read out of the code memory, a selector selects the output of one of the two binarizing circuits and sends the selected image data to a printer. Accordingly, it is possible to obtain a high-quality image which is a mixture of images having different characteristics, such as an image containing character or line drawings, continuous grayscale images, etc.
