<p>PURPOSE:To perform a drawing processing with good response and draw data while securely following the locus traced with a pen on a tablet by operator's input operation by providing a specific coordinate point data input process part. CONSTITUTION:From the start to the end of input indication using a pen 11, the coordinate point data input process part 18 reads coordinate point data of pen indication on the tablet 12 at a constant period and registers the data in an interruption coordinate point table 17. A graphic data drawing process part 16 reads the coordinate point data, registered in the interruption coordinate point table 17, at a period longer than the constant period from the start to the end of the input indication by the pen 11, and connects coordinate points in order to generate and display a handwriting image of a continuous line on a display device 14. The process by the coordinate point data input process part 18 is carried out independently of the process by the graphic data drawing process part 16, so pen coordinate point data of input operation is not omitted because of the relation between the response speeds.</p> |
