PROBLEM TO BE SOLVED: To solve the problem in the conventional processors that the picture of an area, on which plural objects are superposed by plotting objects successively from the depth of the picture is allowed to flicker because the area is overwritten plural times, when a damage area is generated. SOLUTION: The plotting processor 1 is provided with a plotting area list preparation means 5 for preparing a plotting area list, an object plotting means 9 for plotting an object, while clipping the object when the object is superposed to a plotting area, a plotting area list updating means 10 for deleting the plotting area from the plotting area list, dividing the plotting area and adding an area not to be superposed to the object to the list, and a picture updating means 12 for repeating processing for retrieving objects successively from the front of the picture, allowing the object plotting means 9 to plot respective objects and allowing the updating means 10 to update the list.
