PROBLEM TO BE SOLVED: To quantitatively evaluate visibility using a data of a body, without depending on the actual body or sensation of a human being. SOLUTION: An inspection object formed into a CAD data is mesh-divided into models by an inspection-object model generation part 2, and an eye model simplified by a disk shape, a contact-lens shape or the like is set at a position of a subject by an eye model generating part 3. The shape of the inspection object observed by an eye is calculated by a shape factor calculating part 5, a heat-radiation energy amount reaching to the eye is calculated by a heat- radiation calculating part 6, using the shape coefficient, and a correlation between the heat-radiation energy amount, and the visibility is found by a neural network 7 based on a subject experiment. That is, the body required to confirm the visibility and the eye are assumed to be as a heat source having a temperature difference, radiation heat transfer is simulated to calculate the radiated heat energy amount input into the eye, and the visibility is evaluated quantitatively thereby, using the data of the body, without having to depend on the actual body or the sensation of the human being.
