PURPOSE:To attain the real time edition processing of data read by an image scanner by setting a write address and a read address independently to a storage means. CONSTITUTION:An operation table 730 stores plural sets of 3-kind of information DT1, DT2 and DT3. the count of a counter 707 is incremented by 1 every appearance of a coincidence signal, the result is fed to an address terminal of the table 730, all data sets DT1, ST2, ST3 referenced at arrival of a changeover address are switched and the other edition information DT2 and DT3 are updated into others at the same time when a switching address DT1 is updated. thus, in giving the same value as the main scanning address of an image scanner 400 as an address of the read memory 720, the picture data outputted by the image scanner 400 is outputted to a signal line S71 in the same form as an original with a delay by one line of the main scanning. |
