PURPOSE:To attain the output of the same size of pictures both for positive and negative pictures by discrminating whether or not each dot of a picture data to be outputted is required to be moved to special position from the state of surrounding dots in outputting a picture inverting white/black level of a stored picture data so as to control the position of each dot. CONSTITUTION:A picture data for several lines' content of an outputted picture is formed into a data where white/black level is inverted and fetched and stored in an area buffer 7 from a terminal A. Then one line's data is stored from the area buffer 7 to a line memory 8-3. Then the data of the memory 8-3 is stored in a line memory 8-2 and a data for the next one line is stored in the memory 8-3. Then the data in the memory 8-2 is stored in the memory 8-1, the data of the memory 8-3 is stored in the memory 8-2 and the data of the next one line is stored in the memory 8-3. A moving quantity calculating section 9 references a data stored in the memories 8-1, 8-3 as to each dot of the negative data stored in the memory 8-2 to output the negative data, then calculates the moving quantity and direction as to the dot required to be outputted from the normal position to the special position and sends the result to an output control section 6. |
