PURPOSE:To speed up graphic consecutive plotting by unifying graphic data whose attributes are the same and consecutively processible flags are continuously turned on, and executing the consecutive plotting processing with issueing a single plotting command. CONSTITUTION:A graphic processing control processor 3 turns on a consecutively processible flag 5 which can continuously process the graphic data, and stores them to a graphic data memory 2. At the time of plotting, for graphic data 4 successively read from the memory 2, the data 4 whose attributes are the same and flags 5 are continuously turned on are unified, notified to a vector generating processor 6 by issueing a single plotting command, and the consecutive plotting is executed. Consequently, by executing the graphic data whose attributes are the same and the flags 5 are continuously turned on by a single plotting processing, the number of times of the attribute checking of the processor 3 and the number of times of issueing the plotting command are reduced, and a processing load is reduced. |
