Abstract
Exemplary embodiments of the invention provide an eye-flow guiding level calculating system which can plan miniaturization and low cost of a device and surely obtain a suitable eye flow. A layout device, first, detects each vertex of an image object as guiding reference points, based on vector image data. And then, for every guiding reference point, two auxiliary lines are virtually formed to intersect the guiding reference point along an outline of the image object. Subsequently, the direction in which a bisector line of an obtuse angle among angles, made by the virtual auxiliary lines, extends outward from the guiding reference point is calculated as an eye-flow guiding direction. Further, for every guiding reference point, the distance from the center G of the image object up to the guiding reference point is calculated as an eye-flow guiding intensity. According to this construction, it is possible to quantitatively calculate in which direction the image object tends to guide the eye-flow.
