<p>PURPOSE: To process multiple originals at high speed by inserting picture elements and scanning lines at prescribed intervals in the case of enlargement and verification with function information and removing them in reduction verification. CONSTITUTION: A buffer selector 43 enables buffers 44 and 52 so that it frequency-divides L-CNT by two and data is scanned and stored in a buffer memory 49 when L-CNT is an odd-numbered one. Then, buffers 47 and 53 are enabled so that a magnification processing is realized and a memory 50 is controlled so that data can be read from the buffer memory 50. When it is an even-numbered one, the storage operation of new data and a data read operation for a magnification processing are simultaneously executed so that opposite control can be executed. In the case of enlargement magnification by function information, a processing for inserting the picture elements and the scanning lines are inserted at the prescribed intervals is executed. In reduction verification, the picture elements and the scanning lines are removed at the prescribed intervals. The originals of multiple states can independently be processed at high speed.</p> |
