Abstract:
An image forming method for duplicating an original image having a size greater than the maximum size to be placed on the original table, comprising the steps of:dividing the original image into a multiple number of partial images having a size equal to or smaller than the maximum placement size; scanning adjoining partial images in a partially overlapped manner to supply multiple sets of partial images of data; converting the, supplied, multiple partial images of data into reduced, partial images of data by reduction at a desired ratio; storing the converted, reduced partial images of data into multiple reduced partial image storage areas; effecting pattern matching by comparing adjoining reduced partial images of data as to the overlapping image data and determining a matching line to be associated with a storage area of the multiple reduced partial image storage areas; setting a joining position address in another storage area of the multiple reduced partial image storage areas that corresponds to the joining position in each storage area of reduced image data, based on the matching line; and reproducing a reduced image of the original on the predetermined recording medium in accordance with the reduced partial images of data sequentially output directly from the reduced partial image storage area based on the address of the matching line and the another reduced partial image storage area based on the joining position address in a joining manner.
