PURPOSE:To process sequentially inputted data such as picture data on real-time basis by accessing all tracks successively when data on plural pictures to be processed are processed. CONSTITUTION:A CPU114 supplies a disk control system 150 with such as indication that the 1st picture data D1n stored in a track (n) of a disk file 202a is read. A CPU152 controls a disk circuit 204 and moves a read/write head to seek the track (n), transferring and storing the data D1n to and in one bank, e.g. 106A of a buffer memory 106. Then when data D2n on scanning lines of the 2nd picture to be processed corresponding to the track (n) are inputted to a port 102, a CPU114 superposes the data D1n in the bank 106A upon the input data D2n and then stores the resulting data in the bank 106A through the disk control system 150. |
