摘要
The normal vector information generating device generates normal vector information on the surface of an object, and includes: an image information obtaining unit obtaining information about an image of the object, the information including luminance information about luminance of light from the object and polarization information about polarization of the light; a shadow area extracting unit extracting an attached shadow area and a cast shadow area from the image based on the luminance information and the polarization information, the attached shadow area appearing on the surface of the object depending on an angle of incidence light, and the cast shadow area appearing on the surface of a material body when the light is blocked by the object; and a normal vector information generating unit generating normal vector information identifying a normal vector on the surface of the object in the attached shadow area using the polarization information.
