<p>PURPOSE:To attain plotting while observing a hand by displaying plotting information entered by an input pen on a display means and a monitor display screen. CONSTITUTION:When the user uses a digitizer section 501 to plot a drawing with sliding of an input pen 6, an interface circuit 101 of a personal computer main body 1 stores plotting data to a plotting data memory 103. Then a controller 100 reads plotting data stored in the plotting data memory 103 and a part of still image data stored in a still image memory 104 corresponding to the plotting data and uses a synthesis circuit 109 to synthesize them and the synthesized data are transferred to a display data processing section 106 and displayed on a monitor 3. When the controller 100 sends the synthesis data to a digitizer 5, a controller 500 of the digitizer 5 rewrites the data in the display data memory 512 into the synthesis data. New image data plotted date displayed on a liquid crystal display device 510 through the rewrite.</p> |
