<p>A copying machine acquires image data in units of a belt-like area by means of a reading unit (10), converts the image data into YMCK data by means of an image processing unit (20) of the next stage, zooms the YMCK data by means of a zooming section (22), and generates binarized YMCK data by means of a pseudo-gradation processing section (24). The output section (30) of the copying machine successively prints the image data in units of a belt-like area based on the binarized data. The output of the image processing unit (20) is divided into data blocks of 64 dots for a reducing process (data blocks of 128 dots for a unity magnification or magnification process). Therefore, the output of the unit (20) is given to a recognizing device (50) and the device (50) recognizes the output based on the data generated after changing the magnification. As a result, even such a copying machine which print image data on each prescribed area while the machine is reading the image data in units of a belt-like area smaller than the whole area of an original detect image data containing a specific image (specific pattern).</p> |
