<p>PURPOSE:To display a cursor as if the cursor moves smoothly by plotting and displaying the cursor only when the moving quantity at every cursor plotting timing is below the threshold value. CONSTITUTION:The inputted coordinates of the cursor are stored into an interface region 3-1 in the correspondence to operator's inputting of the coordinates of the cursor from a coordinate input device 1. A graphic processing processor 4 determines a distance from the fresh coordinates taken out of this interface region 3-1 and the old coordinates of the previous time at every cursor plotting timing and plots and displays the cursor in the position of the fresh coordinates when the distance is smaller than the threshold. On the other hand, the processor stops plotting the cursor and does not display the cursor when the distance is larger than the threshold. Further, the refreshing of the fresh coordinates to the old coordinates is repeated.</p> |
