Abstract
PURPOSE:To decrease the number of addresses required for the readout in case of DMA transfer and to quicken transfer speed, by splitting the picture elements of picture information inputted to a picture processor into picture element group at every prescribed picture element number and storing the picture element group given with skip address to a storage device. CONSTITUTION:The picture information of a prescribed bit for the 1st line's share of the main scanning inputted serially from a reader section 1 is inputted to a shift register in serial-in/parallel-out in the image memory 2, and split picture element group is stored at each prescribed address. The picture information of a prescribed bit for each line's share is split at each picture element group sequentially to store to the memory 2 and the picture information of the original for one page's share is stored. When the transfer of the picture information between the memory 2 and the buffer memory 7 is DMA-transferred, a DMA request signal is transmitted from a control section 5 to a DMA controller 8, and the information is transferred without using the control section 5 according to the head and final address on the memory set to the control section 5 based on the processing information of the input section 4 by the controller 8.
