摘要
A point data acquisition unit (21) acquires point data indicating a reflection point obtained by an optical sensor (41) that receives reflected light of an emitted light beam reflected at the reflection point. An image data acquisition unit (22) acquires image data of an area surrounding the reflection point indicated by the point data. A luminance calculation unit (23) calculates the smoothness of luminance of the image data. A fog determining unit (24) determines the density of fog based on a distance determined from the point data from the optical sensor (41) to the reflection point and the smoothness of luminance.
