PROBLEM TO BE SOLVED: To provide an imaging system capable of generating an appropriate correction image depending on variation in a state of fog.SOLUTION: According to the present invention, there is provided an imaging system including: an imaging device for acquiring a visual light image of a subject; a radar device that transmits an electromagnetic wave to the subject and receives its reflected wave with two-dimensional space resolution; and an image correction device for correcting the visual light image. The image correction device includes: a distance derivation unit for deriving a distance from the subject in the depth direction on the basis of transmission/reception signals of the radar device; a strength derivation unit for deriving strength of aerosol on the basis of a strength ratio of the transmission/reception signals of the radar device; a brightness derivation unit for deriving brightness of sunlight on the basis of a pixel value of the visual light image and the strength of aerosol; and a pixel value correction unit for deriving a pixel value after correcting the visual light image on the basis of a predetermined function that takes the distance from the subject in the depth direction, the strength of aerosol, and the brightness of sunlight, as its variables.SELECTED DRAWING: Figure 1 |
