Abstract
An in-vehicle monitoring camera device 100 includes: an obstacle detection unit 3 that detects, as first obstacles, obstacles detected by a millimeter-wave radar 11 which might collide with the host vehicle; a collision risk determination unit 4 that detects the time before the respective first obstacles and the vehicle come into contact with each other; a distortion correction unit 2 that generates image 2 by correcting distortion in image 1 captured using a wide-angle lens; and a camera-viewpoint display control unit 5 that generates image 3 by cutting out, from image 2, an image of the first obstacle having the shortest time to collision. Therein, a radar chart 31 indicating the visual field range or the center direction of the visual field of image 3 is superimposed on image 3.
