1. A line symmetrical graphic arrangement device for arranging an input graphic into a line symmetrical figure with respect to a symmetry axis, comprising:

  • a characteristic quantity computing means for computing characteristic quantity depending on the input graphic and selecting characteristic points used for the graphic arrangement;

    a proposed symmetry axis detecting means for requiring proposed symmetry axes of the input graphic based on the characteristic of the shape and the quality of the symmetry axes in the input graphic, which are specified by the characteristic quantity computed by said characteristic quantity computing means;

    a symmetry axis modifying means for modifying the proposed symmetry axes detected by said proposed symmetry axis detecting means according to the quality of the symmetry axes, to obtain the symmetry axes of the input graphic; and

    a characteristic point relocating means for relocating the characteristic points selected by said characteristic quantity computing means with the respective symmetry axes obtained by said symmetry axis modifying means as reference, so to create a symmetrical graphic with respect to the symmetry axes, and whereinsaid proposed symmetry axis detecting means comprisesa first proposed symmetry axis detecting means for detecting first proposed symmetry axes based on the characteristic of the shape and the quality of the symmetry axes in the input graphic which are specified by the characteristic quantity, anda symmetry judging means for judging whether the input graphic is approximately symmetrical with the respective first proposed symmetry axes detected by said first proposed symmetry axis detecting means as reference, and fixing the first proposed symmetry axes as second proposed symmetry axes to be processed by said symmetry axis modifying means when judging that the input graphic is approximately symmetrical.
