<P>PROBLEM TO BE SOLVED: To enable display of a series of orderly circular arcs (or true circle) intended by a user. <P>SOLUTION: The display device includes a tool information detecting part 32 which detects positional information of a drawing fulcrum and drawing variable points of a compass tool 3d, a drawing operation detecting part 34 which detects the drawing operation on the basis of each positional information, drawing line display parts 33 and 34 which display a compass drawing line 64 on the basis of the drawing operation, and a positional deviation detecting part 34 which detects a positional deviation amount ΔC of the drawing fulcrum in a series of the drawing operation. The drawing line display parts 33 and 34 correct either one of the compass drawing line 64 before the positional deviation and the compass drawing line 64 after the positional deviation matching to the drawing fulcrum of the other compass drawing line 64 on the basis of the positional deviation amount ΔC when the positional deviation amount ΔC is larger than 0 and smaller than a first predetermined deviation amount ΔA (ΔA>0). <P>COPYRIGHT: (C)2013,JPO&INPIT |
