<p>PURPOSE:To shorten the processing time for restoration and display of graphics within a range where a graphic to be moved, deleted, etc., does not affect all graphics by providing a graphic display/restoration table which is controlled by a display order processing part and a chaining table which is controlled by a chaining processing part. CONSTITUTION:A display order processing part 4 inputs the grouping information on the displayed graphics from a chaining table 3 via a chaining processing part 2 and controls a graphic display/restoration table 5 to output the contents of the table 5, i.e., the graphic information on the restoring/display order to an input/output control part 1. The table 5 is controlled by the part 4 so as to rearrange the restoring/displaying order of the graphic information which are restored and displayed on the display screen of a display device to store these graphic information in each partial area. Thus it is possible to shorten the processing time for restoration and display of all graphics on the screen even if the graphic displayed on the screen is partly moved, deleted, etc.</p> |
