Publication number: 20180319337Abstract: An image acquisition unit acquires an image around a vehicle. A generator generates a bird's-eye image based on the acquired image. A road surface information acquisition unit acquires information on a road surface around the vehicle. A road surface determination unit determines whether a road surface that requires attention is found by referring to the acquired information on the road surface. When it is determined that a road surface that requires attention is found, an image processor superimposes an image showing the road surface that requires attention on the bird's-eye image.Type: ApplicationFiled: July 13, 2018Publication date: November 8, 2018Inventor: Katsuyuki NAGAI
