<P>PROBLEM TO BE SOLVED: To provide a system for calculating the induction degree of a line of sight by which miniaturization and a low cost for an apparatus are achieved; and an appropriate eye flow is positively obtained. <P>SOLUTION: A layout device 100: firstly detects each vertex of a picture object 10 as an induction reference point on the basis of vector picture data; then, virtually forms two auxiliary lines intersecting the induction reference point along the contour of the picture object 10 on a each induction reference point basis; calculates the direction outward extending the bisector of an obtuse angle out of the angles formed by the virtual auxiliary lines from the induction reference point as a direction for inducing the line of sight; finally, calculates the distance between the center of gravity G of the picture object 10 and the induction reference point as strength for inducing the line of sight on the each induction reference point basis. Consequently, quantitative and appropriate calculation is applied to see which direction easily induces the line of sight by the picture object 10. <P>COPYRIGHT: (C)2005,JPO&NCIPI
