<p>PURPOSE:To speed up an on-screen tablet display processing time, to clearly grasp the whole original picture even when a tablet is displayed and to improve the operability and working efficiency of a CAD system by shortening a switching time from a tablet display screen to a screen displayed before the tablet display. CONSTITUTION:A display picture storing means 7, a display picture switching means 8 and an on-screen tablet display means 9 are connected to a CPU 1 in the CAD system. The means 7 temporarily stores data displayed on a CRT display 2 in a display picture storing part 6. The means 8 accesses the data stored in the storing part 6 and displays a picture displaying the data on the display 2. The means 9 skips the contents of a board part 14 every other line and displays a tablet 12 on the display 2.</p> |
