PURPOSE:To transfer simultaneously processed data to plural output systems by connecting a double-port picture memory having two input/output ports and a picture processing part having three input/output ports to a bus line of a CPU. CONSTITUTION:Picture data supplied from a picture input part 2 are stored temporarily in a double-port picture memory 3. Then these picture data are read out and sent to a picture processing part 4 through a bus line A to undergo necessary picture processing such as the reproduction of these data, the magnification or rotation of pictures, etc. The processed picture data are given to a printer output part 5 via the memory 3 or to a CRT 8 via a picture memory 7 respectively. In this case, the processed picture data are transferred directly and in parallel to both memories 3 and 7 from the part 4 through bus lines B and C independent of each other. |
